Correspondence of environmental tolerances with leaf and branch attributes for six co-occurring species of broadleaf evergreen trees in northern California

 For the angiosperm dominants of northern California’s mixed evergreen forests, this study compares the display of photosynthetic tissue within leaves and along branches, and examines the correspondence between these morphological attributes and the known environmental tolerances of these species. Measurements were made on both sun and shade saplings of six species: Arbutus m e n z i e s i i (Ericaceae), C h r y s o l e p i s c h r y s o p h y l l a (Fagaceae), L i t h o c a r p u s d e n s i f l o r u s (Fagaceae), Quercus c h r y s o l e p i s (Fagaceae), Quercus w i s l i z e n i i (Fagaceae), and Umbellularia c a l i f o r n i c a (Lauraceae). All species had sclerophyllous leaves with thick epidermal walls, but species differed in leaf specific weight, thickness of mesophyll tissues and in the presence of a hypodermis, crystals, secretory idioblasts, epicuticular deposits, and trichomes. The leaves of Arbutus were 2 – 5 times larger than those of C h r y s o l e p i s, L i t h o c a r p u s and Umbellularia and 4 – 10 times larger than those of both Quercus species. Together with differences in branch architecture, these leaf traits divide the species into groups corresponding to environmental tolerances. Shade-tolerant C h r y s o l e p i s, L i t h o c a r p u s, and Umbellularia had longer leaf lifespans and less palisade tissue, leaf area, and crown mass per volume than the intermediate to intolerant Arbutus and Quercus. Having smaller leaves, Quercus branches had more branch mass per leaf area and per palisade volume than other species, whereas Arbutus had less than other species. These differences in display of photosynthetic tissue should contribute to greater growth for Quercus relative to the other species under high light and limited water, for Arbutus under high light and water availability, and for C h r y s o l e p i s, L i t h o c a r p u s, and Umbellularia under limiting light levels.

Phylogenetic systematics of the Empis (Coptophlebia) hyalea-group (Insecta: Diptera: Empididae)

Six clades are inferred from a phylogenetic analysis including 42 species belonging to the Empis (Coptophlebia) hyalea‐group. These clades are named as follows: E. (C.) acris, E. (C.) aspina, E. (C.) atratata, E. (C.) hyalea, E. (C.) jacobsoni and E. (C.) nahaeoensis. The presence of two dorsal more or less developed epandrial projections is considered autapomorphic for the E. (C.) hyalea‐group in addition to two characters previously found to support the monophyly of this group (presence of an unsclerotized zone in the middle of labella and epandrium unpaired). Amongst the cladistically analysed species, 24 are newly described [ E. ( C. ) acris , E. ( C. ) aspina , E. ( C. ) cameronensis , E. ( C. ) duplex , E. ( C. ) incurva , E. ( C. ) inferiseta , E. ( C. ) kuaensis , E. ( C. ) lachaisei , E. ( C. ) lamellalta , E. ( C. ) lata , E. ( C. ) loici , E. ( C. ) longiseta , E. ( C. ) mengyangensis , E. ( C. ) menglunensis , E. ( C. ) missai , E. ( C. ) nimbaensis , E. ( C. ) padangensis , E. ( C. ) parvula , E. ( C. ) projecta , E. ( C. ) pseudonahaeoensis , E. ( C. ) submetallica , E. ( C. ) urumae , E. ( C. ) vitisalutatoris and E. ( C. ) woitapensis ], five are reviewed [E. (C.) hyalea Melander, E. (C.) jacobsoni De Meijere, E. (C.) ostentator Melander, E. (C.) sinensis Melander and E. (C.) thiasotes Melander] and 13 were recently described in two previous papers. Two additional species, E. (C.) abbrevinervis De Meijere and E. (C.) multipennata Melander, are also reviewed but not included in the cladistic analysis since they are only known from the female. A lectotype is designated for E. (C.) jacobsoni. A key is provided to the six clades of the E. (C.) hyalea‐group as well as to species of each clade. A catalogue of the E. (C.) hyalea‐group, including 72 species, is given. The taxonomic status of 25 additional species mainly described by Bezzi and Brunetti, from the Oriental and Australasian regions, is discussed. The E. (C.) hyalea‐group is firstly recorded from the Palaearctic Region and Australia. Finally, the distribution and the habitats of the species compared with their phylogeny suggest a possible relationship between the diversification of the group and forest fragmentations during the Quaternary. © 2005 The Linnean Society of London, Zoological Journal of the Linnean Society, 2005, 145 , 339–391.     

Taxonomic review of the genus Lymantria (Lepidoptera: Erebidae: Lymantriinae) in Korea

A taxonomic review of the Korean Lymantria Hübner, 1819 was conducted. A total of nine species of five subgenera with two unrecorded species are listed: Lymantria (Porthetria) dispar Linnaeus 1758, L. (P.) xylina Swinhoe 1903, L. (Lymantria) monacha (Linnaeus 1758), L. (L.) minomonis Matsumura 1933 (new to Korea), L. (L.) similis monachoides Schintlimeister 2004 (new to Korea), L. (L.) lucescens (Butler 1881), L. (Nyctria) mathura Moore 1865, L. (Collentria) fumida Butler 1877, and L. (Spinotria) bantaizana Matsumura 1933. Lymantria (Lymantria) minomonis and L. (L.) similis monachoides are newly added to the Korean fauna. Lymantria (L.) minomonis was found only on Bogildo Island of Jeollanam‐do in the southern part of Korea, and L. (L.) similis monachoides was collected in central Korea. Lymantria (Porthetria) xylina and L. (Collentria) fumida were not examined in this study, and it is considered that the previous records were due to misidentification or they are only distributed in the northern part of the Korean Peninsula. We provide diagnoses of two unrecorded species and adult habitus and genitalia photos of the Korean Lymantria species.     

Community based natural resource management in Zimbabwe: the experience of CAMPFIRE

Communal Areas Management Programme for Indigenous Resources (CAMPFIRE) is a long-term programmatic approach to rural development that uses wildlife and other natural resources as a mechanism for promoting devolved rural institutions and improved governance and livelihoods. The cornerstone of CAMPFIRE is the right to manage, use, dispose of, and benefit from these resources. Between 1989 and 2006, CAMPFIRE income, mostly from high valued safari hunting, totalled nearly USD 30 million, of which 52 allocated to sub-district wards and villages for community projects and household benefits. Whilst a number of assumptions underlying the success of CAMPFIRE as an innovative model for CBNRM have yet to be met, CAMPFIRE confirms the concept that devolving responsibility and accountability for natural resource management can be highly effective for the collective and participatory management of such resources. Elephant numbers in CAMPFIRE areas have increased and buffalo numbers are either stable or decreased slightly during the life of the programme. However, offtake quotas for these two species have increased with a concomitant decline in trophy quality. Although the amount of wildlife habitat diminished after 1980, following the commencement of CAMPFIRE the rate of habitat loss slowed down and in some specific instances was even reversed. More recently there has been increased pressure on habitats and other natural resources as a consequence of deteriora

Although the amount of wildlife habitat diminished after 1980, following the commencement of CAMPFIRE the rate of habitat loss slowed down and in some specific instances was even reversed. More recently there has been increased pressure on habitats and other natural resources as a consequence of deteriorating socio-economic conditions in the country. Where devolution has been successful, promising results have been achieved and the recent acceptance and implementation of direct payments to communities is probably the most significant development since 2000. That this has happened can be attributed to CAMPFIRE enabling communities to maximize their roles within the existing set of rules, and by so doing, allowing these rules to be challenged. Donor (73%) and government (27%) investments into the programme amounted to 35 million during the period 1989 to 2003. Since 2003 however, donor funding has been reduced to <$600,000 over the past 5 years.     

Phylogenetic position of Madagascan species of Acacia s.l. and new combinations in Senegalia and Vachellia (Fabaceae,Mimosoideae, Acacieae)

The recent worldwide effort to transfer all non‐Australian taxa of Acacia s.l. mostly to the genera Senegalia and Vachellia follows the acceptance of the proposed re‐typification of the genus with an Australian species. The Madagascan species have, as yet, not been included in phylogenetic studies of Acacia s.l. and their position in the new generic classification of Acacia s.l. is therefore still unclear. In this study, plastid DNA sequence data were generated for seven Madagascan species, included in existing matrices for Acacia s.l. and analysed to assess the placement of these species. The results indicate that the Madagascan species are placed either in Senegalia or Vachellia and conform to the morphological characters used to distinguish these genera, despite some taxa having unusual red flowers. New combinations are formalized for Senegalia baronii , S . hildebrandtii , S . kraussiana ssp. madagascariensis , S . menabeensis , S . meridionalis , S . pervillei , S . pervillei ssp. pubescens , S . polhillii , S . sakalava , S . sakalava ssp. hispida , V achellia bellula , V . myrmecophila and V . vigueri . Nomenclatural errors are also corrected for three African taxa and, as such, new combinations are provided for Senegalia fleckii , S . hamulosa and V achellia theronii . © 2015 The Linnean Society of London, Botanical Journal of the Linnean Society, 2015, 179 , 288–294.     

A review of oribatid mites of the family Suctobelbidae (Acariformes,Oribatida) from the caucasus

This paper summarizes the data on the oribatid mite fauna of the family Suctobelbidae Grandjean, 1954, recorded from the Caucasus. The distribution of 47 species of the genera Suctobelba Paoli, 1908, Suctobelbella Jacot, 1937, and Suctobelbila Jacot, 1937 in the territory of the Caucasus is shown. The following five new species and four new subspecies are described: Suctobelba cornigera sp. n., S. flagelliseta sp. n., S. scalpellata caucasica ssp. n., Suctobelbella (Suctobelbella) liacariformis sp. n., S. (S.) acutidens pilososetosa ssp. n., S. (S.) subcornigera maculata ssp. n., S. (Flagrosuctobelba) diversosetosa arilloi ssp. n., S. (F.) nana sp. n., and S. (F.) sensillinuda sp. n. Four species belonging to the genus Suctobelbella changed their status: S. (S.) acutidens duplex (Strenzke, 1950) stat. n., S. (S.) acutidens sarekensis (Forsslund, 1941) stat. n., S. (S.) subcornigera vera (Moritz, 1964) stat. n. and S. (Flagrosuctobelba) forsslundi moritzi Mahunka, 1987 stat. n. S. (S.) hammerae (Krivolutsky, 1965) was synonymized to S. (S.) acutidens duplex. The genus Suctobelbila and the species Suctobelbila dentata europaea Moritz, 1974, Suctobelba altvateri Moritz, 1970, S. atomaria Moritz, 1970, S. secta Moritz, 1970, Suctobelbella (S.) acutidens sarekensis, S. (S.) hastata Pankow, 1986, S. (S.) subcornigera vera stat. n., S. (Flagrosuctobelba) ancorhina Chinone, 2003, S.

(F.) multiplumosa (Hammer, 1979) are recorded from the Caucasus for the first time. A key to the species is given.     

Phylogeny and classification of Aedini (Diptera: Culicidae), based on morphological characters of all life stages

Higher‐level relationships within Aedini, the largest tribe of Culicidae, are explored using morphological characters of eggs, fourth‐instar larvae, pupae, and adult females and males. In total, 172 characters were examined for 119 exemplar species representing the existing 12 genera and 56 subgenera recognized within the tribe. The data for immature and adult stages were analysed separately and in combination using equal (EW) and implied weighting (IW). Since the classification of Aedini is based mainly on adult morphology, we first tested whether adult data alone would support the existing classification. Overall, the results of these analyses did not reflect the generic classification of the tribe. The tribe as a whole was portrayed as a polyphyletic assemblage of Aedes and Ochlerotatus within which eight (EW) or seven (IW) other genera were embedded. Strict consensus trees (SCTs) derived from analyses of the immature stages data were almost completely unresolved. Combining the adult and immature stages data resulted in fewer most parsimonious cladograms (MPCs) and a more resolved SCT than was found when either of the two data subsets was analysed separately. However, the recovered relationships were still unsatisfactory. Except for the additional recovery of Armigeres as a monophyletic genus, the groups recovered in the EW analysis of the combined data were those found in the EW analysis of adult data. The IW analysis of the total data yielded eight MPCs consisting of three sets of two mutually exclusive topologies that occurred in all possible combinations. We carefully studied the different hypotheses of character transformation responsible for each of the alternative patterns of relationship but were unable to select one of the eight MPCs as a preferred cladogram. Overall, the relationships within the SCT of the eight MPCs were a significant improvement over those found by equal weighting. Aedini and all existing genera except Ochlerotatus and Aedes were recovered as monophyletic. Ochlerotatus formed a polyphyletic assemblage basal to Aedes. This group included Haemagogus and Psorophora, and also Opifex in a sister‐group relationship with Oc. (Not.) chathamicus. Aedes was polyphyletic relative to seven other genera, Armigeres, Ayurakitia, Eretmapodites, Heizmannia, Udaya, Verrallina and Zeugnomyia. With the exception of Ae. (Aedimorphus), Oc. (Finlaya), Oc. (Ochlerotatus) and Oc. (Protomacleaya), all subgenera with two or more species included in the analysis were recovered as monophyletic. Rather than leave the generic classification of Aedini in its current chaotic state, we decided a reasonable and conservative compromise classification would be to recognize as genera those groups that are ‘weighting independent’, i.e. those that are common to the results of both the EW and IW analyses of the total data. The SCT of these combined analyses resulted in a topology of 29 clades, each comprising between two and nine taxa, and 30 taxa (including Mansonia) in an unresolved basal polytomy. In addition to ten genera (Armigeres, Ayurakitia, Eretmapodites, Haemagogus, Heizmannia, Opifex, Psorophora, Udaya, Verrallina and Zeugnomyia), generic status is proposed for the following: (i) 32 existing subgenera of Aedes and Ochlerotatus, including nine monobasic subgenera within the basal polytomy, i.e. Ae. (Belkinius), Ae. (Fredwardsius), Ae. (Indusius), Ae. (Isoaedes), Ae. (Leptosomatomyia), Oc. (Abraedes), Oc. (Aztecaedes), Oc. (Gymnometopa) and Oc. (Kompia); (ii) three small subgenera within the basal polytomy that are undoubtedly monophyletic, i.e. Ae. (Huaedes), Ae. (Skusea) and Oc. (Levua), and (iii) another 20 subgenera that fall within the resolved part of the SCT, i.e. Ae. (Aedes), Ae. (Alanstonea), Ae. (Albuginosus), Ae. (Bothaella), Ae. (Christophersiomyia), Ae. (Diceromyia), Ae. (Edwardsaedes), Ae. (Lorrainea), Ae. (Neomelaniconion), Ae. (Paraedes), Ae. (Pseudarmigeres), Ae. (Scutomyia), Ae. (Stegomyia), Oc. (Geoskusea), Oc. (Halaedes), Oc. (Howardina), Oc. (Kenknightia), Oc. (Mucidus), Oc. (Rhinoskusea) and Oc. (Zavortinkius). A clade consisting of Oc. (Fin.) kochi, Oc. (Fin.) poicilius and relatives is raised to generic rank as Finlaya, and Downsiomyia Vargas is reinstated from synonymy with Finlaya as the generic name for the clade comprising Oc. (Fin.) leonis, Oc. (Fin.) niveus and their relatives. Three other species of Finlaya?Oc. (Fin.) chrysolineatus, Oc. (Fin.) geniculatus and Oc. (Fin.) macfarlanei? fall within the basal polytomy and are treated as Oc. (Finlaya) incertae sedis. Ochlerotatus (Ochlerotatus) is divided into three lineages, two of which, Oc. (Och.) atropalpus and Oc. (Och.) muelleri, are part of the basal polytomy. The remaining seven taxa of Oc. (Ochlerotatus) analysed, including the type species, form a reasonably well‐supported group that is regarded as Ochlerotatus s.s. Ochlerotatus (Rusticoidus) is retained as a subgenus within Ochlerotatus s.s. Ochlerotatus (Nothoskusea) is recognized as a subgenus of Opifex based on two unique features that support their sister‐group relationship. A new genus, Tanakaius gen. nov. , is proposed for Oc. (Fin.) togoi and the related species Oc. (Fin.) savoryi. The taxonomic status and generic placement of all currently valid species of Aedini are listed in an appendix. © 2004 The Linnean Society of London, Zoological Journal of the Linnean Society, 2004, 142 , 289?368.

Molecular phylogeny and systematics of leaf‐mining flies (Diptera: Agromyzidae): delimitation of Phytomyza Fallén sensu lato and included species groups,with new insights on morphological and host‐use evolution

Abstract Phytomyza Fallén is the largest genus of leaf‐mining flies (Agromyzidae), with over 530 described species. Species of the superficially similar genus Chromatomyia Hardy have been included in Phytomyza by some authors and the status of the genus remains uncertain. Using 3076 bp of DNA sequence from three genes [cytochrome oxidase I (COI), CAD (rudimentary), phosphogluconate dehydrogenase (PGD)] and 113 exemplar species, we identified and tested the monophyly of host‐associated species groups in Phytomyza and Chromatomyia and investigated the phylogenetic relationships among these groups. Chromatomyia is polyphyletic and nested largely within Phytomyza; two small groups of species, however, are related more closely to Ptochomyza and Napomyza. Therefore, we synonymize Chromatomyia syn.n. , Ptochomyza syn.n. , and Napomyza syn.n. with Phytomyza, recognizing Ptochomyza, Napomyza and Phytomyza sensu stricto as subgenera of Phytomyza. We recognize five major clades within Phytomyza sensu stricto that comprise the majority of species ascribed previously to Chromatomyia and Phytomyza. Many species groups recognized previously were recovered as monophyletic, or virtually so, but some (e.g. robustella and atomaria groups) required emendation. On the basis of the proposed phylogeny and recent taxonomic literature, we present a preliminary revision of 24 species groups within Phytomyza, but leave many species unplaced. Evolution of internal pupariation (within the host’s tissue), regarded as a defining character of the former Chromatomyia, is discussed with regard to the new phylogeny, and we suggest a correlation with stem or leaf midrib mining. The large size of the Phytomyza lineage and an inferred pattern of host family‐specific species radiations make it a promising candidate for the study of macroevolutionary patterns of host shift and diversification in phytophagous insects. The proposed generic synonymies necessitate a number of new combinations. The following 46 species described in Chromatomyia are transferred to Phytomyza: P. actinidiae (Sasakawa) comb.n. , P. alopecuri (Griffiths) comb.n. , P. arctagrostidis (Griffiths) comb.n. , P. beigerae (Griffiths) comb.n. , P. blackstoniae (Spencer) comb.n. , P. centaurii (Spencer) comb.n. , P. chamaemetabola (Griffiths) comb.n. , P. cinnae (Griffiths) comb.n. , P. compta (Spencer) comb.n. , P. cygnicollina (Griffiths) comb.n. , P. doolittlei (Spencer) comb.n. , P. elgonensis (Spencer) comb.n. , P. eriodictyi (Spencer) comb.n. , P. flavida (Spencer) comb.n. , P. fricki (Griffiths) comb.n. , P. furcata (Griffiths) comb.n. , P. griffithsiana (Beiger) comb.n. , P. hoppiella (Spencer) comb.n. , P. ixeridopsis (Griffiths) comb.n. , P. kluanensis (Griffiths) comb.n. , P. leptargyreae (Griffiths) comb.n. , P. linnaeae (Griffiths) comb.n. , P. luzulivora (Spencer) comb.n. , P. mimuli (Spencer) comb.n. , P. mitchelli (Spencer) comb.n. , P. montella (Spencer) comb.n. , P. nigrilineata (Griffiths) comb.n. , P. nigrissima (Spencer) comb.n. , P. orbitella (Spencer) comb.n. , P. paraciliata (Godfray) comb.n. , P. poae (Griffiths) comb.n. , P. pseudomilii (Griffiths) comb.n. , P. qinghaiensis (Gu) comb.n. , P. rhaetica (Griffiths) comb.n. , P. scabiosella (Beiger) comb.n. , P. seneciophila (Spencer) comb.n. , P. shepherdiana (Griffiths) comb.n. , P. spenceriana (Griffiths) comb.n. , P. styriaca (Griffiths) comb.n. , P. subnigra (Spencer) comb.n. , P. suikazurae (Sasakawa) comb.n. , P. symphoricarpi (Griffiths) comb.n. , P. syngenesiae (Hardy) comb.n. , P. thermarum (Griffiths) comb.n. , P. torrentium (Griffiths) comb.n. and P. tschirnhausi (Griffiths) comb.n.

Mutually exclusive distribution of the sap and eag S-layer genes and the lytB/lytA cell wall hydrolase genes in Bacillus thuringiensis

Recently, two Bacillus thuringiensis strains were reported to synthesize parasporal inclusion bodies made not of the expected crystal (Cry) proteins but rather of the surface layer proteins (SLP) Sap (encoded by sap) and EA1 (encoded by eag), respectively. Whether the presence of the sap and eag genes is restricted to these two B. thuringiensis strains or ubiquitous in B. thuringiensis is unknown. We report here the distribution of the sap and eag genes in B. thuringiensis. Strains in the Bacillus cereus group were added for comparison purposes. We show that sap and eag are either present in tandem in 35% of the B. thuringiensis strains analysed and absent in 65% of the strains. When absent, a different tandem, the lytB/lytA cell wall hydrolase genes, is present. The distribution of the sap and eag S-layer and the lytB/lytA cell wall hydrolase genes is not species-specific in B. thuringiensis, B. cereus and Bacillus weihenstephanensis. Bacillus anthracis and Bacillus mycoides harbor sap and eag but not lytB/lytA. The sap, eag and lytB/lytA genes were absent in Bacillus pseudomycoides. Clearly, the distribution of the sap and eag S-layer and the lytB/lytA cell wall hydrolase genes in B. thuringiensis and in the Bacillus cereus group is mutually exclusive. We also showed that two genes involved in cell wall metabolism, csaA and csaB, are present not only upstream of the sap and eag S-layer genes, but also upstream of the lytB/lytA tandem in strains where sap and eag are absent. Bootstrapped neighbor-joining trees were inferred from the translated amino acid sequences of sap, eag and the tandem lytB/lytA, respectively.     

Phylogenetic systematics of Archembiidae (Embiidina, Insecta)

Abstract. A cladistic analysis of the American genera of Embiidae is presented, using fifty‐seven representative taxa and ninety‐four morphological characters. The results support the elevation (and significant re‐delimitation) of the subfamily Archembiinae to family level; as delimited here, Archembiidae, revised status, includes the genera Ecuadembia n.gen., Calamoclostes Enderlein, Archembia Ross, Embolyntha Davis, Xiphosembia Ross, Ochrembia Ross, Dolonembia Ross, Conicercembia Ross, Neorhagadochir Ross, Pachylembia Ross, Rhagadochir Enderlein, Litosembia Ross, Navasiella Davis, Ambonembia Ross, Malacosembia Ross, Biguembia Szumik, Gibocercus Szumik and Pararhagadochir Davis. The results also indicate that some genera recently proposed are unjustified and therefore they are synonymized: Argocercembia Ross (a junior synonym of Embolyntha), Brachypterembia Ross (Neorhagadochir), Scelembia Ross (Rhagadochir), Ischnosembia Ross (Ambonembia) and Aphanembia Ross (Biguembia); all new synonymy. The new genus Ecuadembia is described (type species Archembia arida Ross). Ischnosembia surinamensis (Ross) is returned to the genus Pararhagadochir. The following species synonymies are established: Archembia lacombea Ross 1971 = Archembia kotzbaueri (Navas 1925), Archembia peruviana Ross 2001 = Archembia batesi (MacLachlan 1877), and Conicercembia septentrionalis (Mariño & Márquez 1988) = Conicercembia tepicensis Ross 1984; all new synonymy. The family Archembiidae, and all its constituent genera, are diagnosed and described. The genus Microembia Ross (originally described as an Embiidae) is transferred to Anisembiidae. Pachylembiinae, Scelembiinae, and Microembiinae proposed by Ross are unsupported by the present cladistic analysis. 1     

Antifungal activity of essential oils against three vegetative-compatibility groups of <Emphasis Type="Italic">Verticillium dahliae</Emphasis>

The antifungal activities of volatile phase effects of essential oils from Origanum onites, O. syriacum, O. minutiflorum, O. vulgare, O, marjorana, Thymus vulgaris, T. serpyllum, Rosmarinus officinalis, Salvia officinalis and Micromeria fruticosa were evaluated for their ability to inhibit growth of three vegetative compatibility groups (VCGs) of Verticillium dahliae. Carvacrol was the main component of O. onites, O. minutiflorum and O. vulgare essential oils, while γ-terpinene was the main component of O. syriacum. P-cymene and thymol were the dominant component of T. vulgaris and T. serpyllum. β- thujone and l-camphor were the main component of S. officinalis. Polegone and isomenthone were the dominant components of M. fruticosa essential oil. Based on the in vitro test, the degree of fungistatical effects can be ranked in the following order of inhibition: O. syriacum = O. onites = O. minutiflorum = O. vulgare = T. vulgaris > T. serpyllum > M. fruticosa > S. officinalis = O. marjorana > R. officinalis. The essential oils of S. officinalis, O. marjorana and R. officinalis displayed moderate antifungal activity, that increased with increasing concentrations. Among the VCGs, VCG2A and VCG4B were found to be highly sensitive to the essential oils. The essential oils of O. syriacum, O. onites, O. minutiflorum, O. vulgare and T. vulgaris were the most efficacious, demonstrating strong antifungal activity against all of the tested VCGs of V. dahliae at relatively low concentrations and they could find practical application as natural fungicides in the prevention and protection of plants from V. dahliae infections.     

Variation in Wolbachia cidB gene,but not cidA,is associated with cytoplasmic incompatibility mod phenotype diversity in Culex pipiens

Endosymbiotic Wolbachia bacteria are, to date, considered the most widespread symbionts in arthropods and are the cornerstone of major biological control strategies. Such a high prevalence is based on the ability of Wolbachia to manipulate their hosts' reproduction. One manipulation called cytoplasmic incompatibility (CI) is based on the death of the embryos generated by crosses between infected males and uninfected females or between individuals infected with incompatible Wolbachia strains. CI can be seen as a modification‐rescue system (or mod‐resc) in which paternal Wolbachia produce mod factors, inducing embryonic defects, unless the maternal Wolbachia produce compatible resc factors. Transgenic experiments in Drosophila melanogaster and Saccharomyces cerevisiae converged towards a model where the cidB Wolbachia gene is involved in the mod function while cidA is involved in the resc function. However, as cidA expression in Drosophila males was required to observe CI, it has been proposed that cidA could be involved in both resc and mod functions. A recent correlative study in natural Culex pipiens mosquito populations has revealed an association between specific cidA and cidB variations and changes in mod phenotype, also suggesting a role for both these genes in mod diversity. Here, by studying cidA and cidB genomic repertoires of individuals from newly sampled natural C. pipiens populations harbouring wPipIV strains from North Italy, we reinforce the link between cidB variation and mod phenotype variation fostering the involvement of cidB in the mod phenotype diversity. However, no association between any cidA variants or combination of cidA variants and mod phenotype variation was observed. Taken together our results in natural C. pipiens populations do not support the involvement of cidA in mod phenotype variation.     

Grosmannia and Leptographium spp. associated with conifer-infesting bark beetles in Finland and Russia, including Leptographium taigense sp. nov.

Species of Grosmannia with Leptographium anamorphs include important forest pathogens and agents of blue stain in timber. They are commonly found in association with forest pests, such as bark beetles. During a survey of ophiostomatoid fungi in eastern parts of Finland and neighboring Russia, species belonging to the genus Grosmannia were isolated from 12 different bark beetle species infesting Picea abies and Pinus sylvestris, the most economically important conifers in the region. Identification of these fungi was based on morphology, DNA sequence comparisons for three gene regions and phylogenetic analyses. A total of ten taxa were identified. These belonged to six different species complexes in Grosmannia. The phylogenetic analyses provided an opportunity to redefine the G. galeiformis-, L. procerum-, L. lundbergii-, G. piceiperda-, G. olivacea- and G. penicillata-complexes, and to consider the species emerging from the survey within the context of these complexes. The species included G. galeiformis, G. olivacea, L. chlamydatum, L. lundbergii, L. truncatum and a novel taxon, described here as L. taigense sp. nov. In addition, species closely related to G. cucullata, G. olivaceapini comb. nov., G. piceiperda and L. procerum were isolated but their identity could not be resolved. The overall results indicate that the diversity of Grosmannia species in the boreal forests remains poorly understood and that further studies are needed to clarify the status of several species or species complexes.     

Genus Bembidion Latreille (Coleoptera: Carabidae) in New Zealand: A revision

The cosmopolitan genus Bembidion is represented in New Zealand by 20 species, of which 19 are endemic; B. brullei appears to be a recent introduction. On phenetic characters the species fall into 7 subgenera, as follows: Zeplataphus n.subg.—maorinum Bates, dehiscens Broun, charile Bates, granuliferum n.sp., townsendi n.sp., tairuense Bates; Zeactedium Netolitzky—orbiferum Bates, musae Broun; Zeperyphodes n.subg.—callipeplum Bates; Zeperyphus n.subg.—actuarium Broun; Zemetal‐lina n.subg.—chalceipes Bates, solitarium n.sp., anchonoderum Bates, tekapoense Broun, wanakense n.sp., urewerense n.sp., hokitikense Bates, parviceps Bates; Ananotaphus Netolitzky—rotundicolle Bates; Notaphus Stephens—brullei Gemminger & Harold. The North Island population of maorinum is distinct from the typical South Island form in having reduced microscrulpture on the elytra, and is here separated as levatum n.ssp. An apparent geographic isolate of anchonoderum, represented by 2 females from Stewart Island, is provisionally recognised as stewartense n.ssp. The polymorphic complex within subg. Ananotaphus is here regarded as a single species, of which the North Island population is sufficiently distinct to warrant subspecific status as eustictum Bates; however, intergrades occur in the north‐west of the South Island. The following names fall into synonymy: latiusculum Broun (= maorinum); diaphanum Broun (= musae); nesophilum Broun (= callipeplum)’, tinctellum Broun (= chalceipes);antipodum Broun (= anchonoderum)’, tantillum Broun and probably attenuatum Broun (=hokitikense)’, clevedonense Broun and waikatoense Broun (= rotundicolle, ssp. eustictum)’, gameani Jeannel (= brullei). The relationships and aspects of the biology and ecology of the New Zealand Bembidion fauna are discussed.     

Molecular identification of endophytic fungi from medicinal plant <Emphasis Type="Italic">Huperzia serrata</Emphasis> based on rDNA ITS analysis

Fifty-two endophytic fungi strains with different colony morphologies were isolated from stems, leaves and roots of Huperzia serrata (Thunb. ex Murray) Trevis. collected from Bawangling Reserve of Hainan Province in southern China. They were identified mainly based on rDNA ITS sequences and phylogenetic analysis. The results showed that all strains belonged to four classes, i.e. Sordariomycetes (92.31%), Dothideomycetes (3.85%), Pezizomycetes (1.92%) and Agaricomycetes (1.92%). Forty-seven strains were identified at the genus level, including Glomerella (Colletotrichum), Hypocrea (Trichoderma), Pleurostoma, Chaetomium, Coniochaeta (Lecythophora), Daldinia, Xylaria, Hypoxylon, Nodulisporium, Cazia and Phellinus. As to the other five strains, three were identified at the order level and two at the family level, indicating that a great diversity of fungi taxa exists in H. serrata. Most isolated strains belonged to the genus of Glomerella (Colletotrichum) and Hypoxylon, twenty-one from Glomerella and its anamorph Colletotrichum (42.3% of total isolated strains) and ten from Hypoxylon (19.2% of total isolated strains). Pleurostoma, Chaetomium, Coniochaeta (Lecythophora), Daldinia, Xylaria, Hypoxylon, Nodulisporium, Cazia and Phellinus were reported as endophytic fungi isolated from H. serrata for the first time.     

Localization of neuropeptide Y-immunoreactive cells and fibres in the brain of the Japanese quail

Summary In the present study, we have demonstrated, by means of the biotin-avidin method, the widespread distribution of neuropeptide Y (NPY)-immunoreactive structures throughout the whole brain of the Japanese quail (Coturnix coturnix japonica). The prosencephalic region contained the highest concentration of both NPY-containing fibres and perikarya. Immunoreactive fibres were observed throughout, particularly within the paraolfactory lobe, the lateral septum, the nucleus taeniae, the preoptic area, the periventricular hypothalamic regions, the tuberal complex, and the ventrolateral thalamus. NPY-immunoreactive cells were represented by: a) small scattered perikarya in the telencephalic portion (i.e. archistriatal, neostriatal and hyperstriatal regions, hippocampus, piriform cortex); b) medium-sized cell bodies located around the nucleus rotundus, ventrolateral, and lateral anterior thalamic nuclei; c) small clustered cells within the periventricular and medial preoptic nuclei. The brainstem showed a less diffuse innervation, although a dense network of immunopositive fibres was observed within the optic tectum, the periaqueductal region, and the Edinger-Westphal, linearis caudalis and raphes nuclei. Two populations of large NPY-containing perikarya were detected: one located in the isthmic region, the other at the boundaries of the pons with the medulla. The wide distribution of NPY-immunoreactive structures within regions that have been demonstrated to play a role in the control of vegetative, endocrine and sensory activities suggests that, in birds, this neuropeptide is involved in the regulation of several aspects of cerebral functions.Abbreviations AA archistriatum anterius - AC nucleus accumbens - AM nucleus anterior medialis - APP avian pancreatic polypeptide - CNS centrai nervous system - CO chiasma opticum - CP commissura posterior - CPi cortex piriformis - DIC differential interferential contrast - DLAl nucleus dorsolateralis anterior thalami, pars lateralis - DLAm nucleus dorsolateralis anterior thalami, pars medialis - E ectostriatum - EW nucleus of Edinger-Westphal - FLM fasciculus longitudinalis medialis - GCt substantia grisea centralis - GLv nucleus geniculatus lateralis, pars ventralis - HA hyperstriatum accessorium - Hp hippocampus - HPLC high performance liquid chromatography - HV hyperstriatum ventrale - IF nucleus infundibularis - IO nucleus isthmo-opticus - IP nucleus interpeduncularis - IR immunoreactive - LA nucleus lateralis anterior thalami - LC nucleus linearis caudalis - LFS lamina frontalis superior - LH lamina hyperstriatica - LHRH luteinizing hormone-releasing hormone - LoC locus coeruleus - LPO lobus paraolfactorius - ME eminentia mediana - N neostriatum - NC neostriatum caudale - NPY neuropeptide Y - NIII nervus oculomotorius - NV nervus trigeminus - NVI nervus facialis - NVIIIc nervus octavus, pars cochlearis - nIV nucleus nervi oculomotorii - nIX nucleus nervi glossopharyngei - nBOR nucleus opticus basalis (ectomamilaris) - nCPa nucleus commissurae pallii - nST nucleus striae terminalis - OM tractus occipitomesencephalicus - OS nucleus olivaris superior - PA palaeostriatum augmentatum - PBS phosphate-buffered saline - POA nucleus praeopticus anterior - POM nucleus praeopticus medialis - POP nucleus praeopticus periventricularis - PP pancreatic polypeptide - PYY polypeptide YY - PVN nucleus paraventricularis magnocellularis - PVO organum paraventriculare - R nucleus raphes - ROT nucleus rotundus - RP nucleus reticularis pontis caudalis - Rpc nucleus reticularis parvocellularis - RPgc nucleus reticularis pontis caudalis, pars gigantocellularis - RPO nucleus reticularis pontis oralis - SCd nucleus subcoeruleus dorsalis - SCv nucleus subcoeruleus ventralis - SCNm nucleus suprachiasmaticus, pars medialis - SCNl nucleus suprachiasmaticus, pars lateralis - SL nucleus septalis lateralis - SM nucleus septalis medialis - Ta nucleus tangentialis - TeO tectum opticum - Tn nucleus taeniae - TPc nucleus tegmenti pedunculo-pontinus, pars compacta - TSM tractus septo-mesencephalicus - TV nueleus tegmenti ventralis - VeL nucleus vestibularis lateralis - VLT nucleus ventrolateralis thalami - VMN nucleus ventromedialis hypothalami A preliminary report of this study was presented at the 15th Conference of European Comparative Endocrinologists, Leuven, Belgium, September 1990     

Molecular identification of species in Prunus sect. Persica (Rosaceae), with emphasis on evaluation of candidate barcodes for plants

Abstract Species of Prunus L. sect. Persica are not only important fruit trees, but also popular ornamental and medicinal plants. Correct identification of seedlings, barks, or fruit kernels is sometimes required, but no reliable morphological characters are available. Nowadays, the technique of DNA barcoding has the potential to meet such requirements. In this study, we evaluated the suitability of 11 DNA loci (atpB‐rbcL, trnH‐psbA, trnL‐F, trnS‐G, atpF‐H, rbcL, matK, rpoB, rpoC1, nad1, and internal transcribed spacer [ITS]) as candidate DNA barcodes for peaches, using samples from 38 populations, covering all the species in sect. Persica. On the whole, the primers worked well in this group and sequencing difficulties were met only in the case of ITS locus. Five loci (rbcL, matK, rpoB, rpoC, and nad1) have very low variation rates, whereas atpB‐rbcL, atpF‐H, trnH‐psbA, trnL‐F and trnS‐G show more variability. The most variable loci, atpB‐rbcL and trnH‐psbA, can distinguish three of the five species. Two two‐locus combinations, atpB‐rbcL+trnL‐F and atpB‐rbcL+atpF‐H, can resolve all five species. We also find that identification powers of the loci are method‐dependent. The NeighborNet method shows higher species identification power than maximum parsimony, neighbor joining, and unweighted pair group method with arithmetic mean methods.     

Phylogeny and systematics of the bee genus Osmia (Hymenoptera: Megachilidae) with emphasis on North American Melanosmia: subgenera,synonymies and nesting biology revisited

The predominantly Holarctic bee genus Osmia Panzer is species‐rich and behaviourally diverse. A robust phylogeny of this genus is important for understanding the evolution of the immense variety of morphological and behavioural traits exhibited by this group. We infer a phylogeny of Osmia using DNA sequence data obtained from three nuclear genes (elongation factor 1‐α, LW‐rhodopsin and CAD) and the mitochondrial gene COI. Our taxon sampling places special attention on North American members of the subgenus Melanosmia Schmiedeknecht; we discuss the novel placement of a number of species traditionally assigned to O. (Melanosmia) and examine the relative support for alternative classifications of this species‐rich subgenus. We use this new phylogeny to guide a reassessment of morphological and behavioural characters within Osmia. Our results provide support for the recognition of Osmia (Hapsidosmia), subgen.n ., a monotypic subgenus containing Osmia iridis Cockerell & Titus. We synonymize Osmia (Mystacosmia) Snelling under O. (Melanosmia), syn.n . We synonymize Osmia (Acanthosmioides) Ashmead under O. (Melanosmia), syn.n ., propose ‘odontogaster species group’ as a replacement for the subgeneric name Acanthosmioides, and refine the morphological characters that serve to diagnose the species group. We additionally propose ‘nigrifrons species group’ for a clade within O. (Melanosmia) containing most species formerly placed in Osmia (Centrosmia) Robertson. We demonstrate more cohesive patterns of nest substrate use in the nigrifrons and odontogaster species groups than was previously believed to occur, reconsider character polarity of aspects of the female mandible, and show that a large number of morphological characters have evolved convergently within the genus. In order to facilitate discussion of relevant taxa, we propose the following 15 new synonymies: O. bakeri Sandhouse under O. melanopleura Cockerell; O. crenulaticornis Michener under O. pinorum Cockerell; O. claremontensis Michener under O. sedula Sandhouse; O. cockerelli Sandhouse under O. dakotensis Michener; O. francisconis White under O. enixa Sandhouse; O. hurdi White under O. austromaritima Michener; O. sladeni Sandhouse under O. nifoata Cockerell; O. titusi Cockerell under O. phenax Cockerell; O. subtrevoris Cockerell, O. physariae Cockerell, and O. erecta Michener under O. giliarum Cockerell; and O. universitatis Cockerell, O. integrella Cockerell, O. amala Cockerell, and O. metitia Cockerell under O. nigrifrons Cresson, syn.n . We remove O. wyomingensis Michener from synonymy with O. nifoata Cockerell, stat.n ., and O. pinorum Cockerell from synonymy with O. physariae Cockerell, stat.n .
