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.

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.     

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.     

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.     

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.     

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.     

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.     

Phylogeny and classification of tribe Aedini (Diptera: Culicidae)

The phylogeny and classification of tribe Aedini are delineated based on a cladistic analysis of 336 characters from eggs, fourth‐instar larvae, pupae, adult females and males, and immature stage habitat coded for 270 exemplar species, including an outgroup of four species from different non‐aedine genera. Analyses of the data set with all multistate characters treated as unordered under implied weights, implemented by TNT version 1.1, with values of the concavity constant K ranging from 7 to 12 each produced a single most parsimonious cladogram (MPC). The MPCs obtained with K values of 7–9 were identical, and that for K = 10 differed only in small changes in the relationships within one subclade. Because values of K < 7 and > 10 produced large changes in the relationships among the taxa, the stability of relationships exemplified by the MPC obtained from the K = 9 analysis is used to interpret the phylogeny and classification of Aedini. Clade support was assessed using parsimony jackknife and symmetric resampling. Overall, the results reinforce the patterns of relationships obtained previously despite differences in the taxa and characters included in the analyses. With two exceptions, all of the groups represented by two or more species were once again recovered as monophyletic taxa. Thus, the monophyly of the following genera and subgenera is corroborated: Aedes, Albuginosus, Armigeres (and its two subgenera), Ayurakitia, Bothaella, Bruceharrisonius, Christophersiomyia, Collessius (and its two subgenera), Dahliana, Danielsia, Dobrotworskyius, Downsiomyia, Edwardsaedes, Finlaya, Georgecraigius (and its two subgenera), Eretmapodites, Geoskusea, Gilesius, Haemagogus (and its two subgenera), Heizmannia (and subgenus Heizmannia), Hopkinsius (and its two subgenera), Howardina, Hulecoeteomyia, Jarnellius, Kenknightia, Lorrainea, Macleaya, Mucidus (and its two subgenera), Neomelaniconion, Ochlerotatus (subgenera Chrysoconops, Culicelsa, Gilesia, Pholeomyia, Protoculex, Rusticoidus and Pseudoskusea), Opifex, Paraedes, Patmarksia, Phagomyia, Pseudarmigeres, Rhinoskusea, Psorophora (and its three subgenera), Rampamyia, Scutomyia, Stegomyia, Tanakaius, Udaya, Vansomerenis, Verrallina (and subgenera Harbachius and Neomacleaya), Zavortinkius and Zeugnomyia. In addition, the monophyly of Tewarius, newly added to the data set, is confirmed. Heizmannia (Mattinglyia) and Verrallina (Verrallina) were found to be paraphyletic with respect to Heizmannia (Heizmannia) and Verrallina (Neomacleaya), respectively. The analyses were repeated with the 14 characters derived from length measurements treated as ordered. Although somewhat different patterns of relationships among the genera and subgenera were found, all were recovered as monophyletic taxa with the sole exception of Dendroskusea stat. nov. Fifteen additional genera, three of which are new, and 12 additional subgenera, 11 of which are new, are proposed for monophyletic clades, and a few lineages represented by a single species, based on tree topology, the principle of equivalent rank, branch support and the number and nature of the characters that support the branches. Acartomyia stat. nov. , Aedimorphus stat. nov. , Cancraedes stat. nov. , Cornetius stat. nov. , Geoskusea stat. nov. , Levua stat. nov. , Lewnielsenius stat. nov. , Rhinoskusea stat. nov. and Sallumia stat. nov., which were previously recognized as subgenera of various genera, are elevated to generic status. Catageiomyia stat. nov. and Polyleptiomyia stat. nov. are resurrected from synonymy with Aedimorphus, and Catatassomyia stat. nov. and Dendroskusea stat. nov. are resurrected from synonymy with Diceromyia. Bifidistylus gen. nov. (type species: Aedes lamborni Edwards) and Elpeytonius gen. nov. (type species: Ochlerotatus apicoannulatus Edwards) are described as new for species previously included in Aedes (Aedimorphus), and Petermattinglyius gen. nov. (type species: Aedes iyengari Edwards) and Pe. (Aglaonotus) subgen. nov. (type species: Aedes whartoni Mattingly) are described as new for species previously included in Aedes (Diceromyia). Four additional subgenera are recognized for species of Ochlerotatus, including Oc. (Culicada) stat. nov. (type species: Culex canadensis Theobald), Oc. (Juppius) subgen. nov. (type species: Grabhamia caballa Theobald), Oc. (Lepidokeneon) subgen. nov. (type species: Aedes spilotus Marks) and Oc. (Woodius) subgen. nov. (type species: Aedes intrudens Dyar), and seven are proposed for species of Stegomyia: St. (Actinothrix) subgen. nov. (type species: Stegomyia edwardsi Barraud), St. (Bohartius) subgen. nov. (type species: Aedes pandani Stone), St. (Heteraspidion) subgen. nov. (type species: Stegomyia annandalei Theobald), St. (Huangmyia) subgen. nov. (type species: Stegomyia mediopunctata Theobald), St. (Mukwaya) subgen. nov. (type species: Stegomyia simpsoni Theobald), St. (Xyele) subgen. nov. (type species: Stegomyia desmotes Giles) and St. (Zoromorphus) subgen. nov. (type species: Aedes futunae Belkin). Due to the unavailability of specimens for study, many species of Stegomyia are without subgeneric placement. As is usual with generic‐level groups of Aedini, the newly recognized genera and subgenera are polythetic taxa that are diagnosed by unique combinations of characters. The analysis corroborates the previous observation that ‘Oc. (Protomacleaya)’ is a polyphyletic assemblage of species.     

Cytological and Reproductive Studies of Japanese Diplazium (Woodsiaceae; Pteridophyta). III. The Cytological Complexity of Species Groups with Simply Pinnate to Bipinnatifid Leaves

Diplazium with simply pinnate or bipinnatifid leaves. Diplazium wichurae var. wichurae, D. wichurae var. amabile, D. okudairae, and D. pin-faense are sexual diploids (2n=82; n=41II); D.× kidoi and D. × okudairaeoides are sterile diploids (2n= 82; meiosis irregular); D. donianum var. donianum is an apomictic triploid (2n=123; n=123II); D. donianum var. aphanoneuron is a sterile triploid (2n=123; meiosis irregular); D. crassiusculum, D. cavalerianum, D. incomptum, D. longicarpum, and D. pullingeri are sexual tetraploids (2n= 164; n=82II); and D. lobatum is an apomictic tetraploid (2n=164; n=164II). This is the first report of the chromosome numbers of D. lobatum, D. crassiusculum, D. incomptum, D. longicarpum, D. pullingeri, and D. × okudairaeoides, as well as the mitotic chromosome numbers of D. wichurae var. amabile, D. okudairae, D. pinfaense, and D. ×kidoi. The mitotic chromosome number, meiotic behavior, sterility, and allozyme analysis confirm that D. × kidoi and D. × okudairaeoides are hybrids between D. pin-faense and D. wichurae var. wichurae and D. okudairae and D. wichurae var. wichurae, respectively. Diplazium with simply pinnate to bipinnatifid leaves displayed an extraordinary cytological and reproductive complexity: a polyploidal series with diploids to hexaploids, sexual and apomictic reproduction, and natural hybridization.

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.     

Species composition and distribution patterns of baetid nymphs (Baetidae: Ephemeroptera) in a Japanese stream

Species composition and distributional patterns among nymphs of five baetid genera (Ephemeroptera), Baetis, Tenuibaetis, Labiobaetis, Nigrobaetis and Alainites were investigated in Yura Stream, Kyoto Prefecture. I collected 13 species: B. sahoensis, B. thermicus, B. sp. F, B. sp. J, B. sp. M1, B. sp. S1, T. sp. E, T. sp. H, L. sp. G, N. chocoratus, N. sp. D, N. sp. I and A. yoshinensis, among which B. thermicus, B. sp. S1 and T. sp. E were dominant, whereas B. sahoensis, B. sp. F, B. sp. M1 and N.sp. I were scarce. Based on their longitudinal distribution patterns, the 13 species were classified into upper species, upper-middle species, middle species, middle-lower species and lower species. Baetis thermicusand A. yoshinensis showed long downstream tails. Baetis sp. J and N. sp. D extended their longitudinal distribution upstream in summer. With regard to habitat preference, Alainites and Labiobaetis were restricted to riffle and vegetated zones, respectively. Tenuibaetis consisted of riffle-vegetated zone species, whereas Baetis and Nigrobaetiscontained both riffle species and ubiquitous species. Habitat partitioning (`sumiwake') along the watercourse (macro-sumiwake) was evident in Tenuibaetis, and that between habitat types (micro-sumiwake) in Labiobaetis vs. Baetis (rhodanigroup species) and Labiobaetis vs. Alainites.     

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.     

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.

Revision of the Thelastomatoidea,Oxyurida of invertebrate hosts I. Thelastomatidae

The Family Thelastomidae (Thelastomatoidea; Oxyurida; Nematoda) is revised, genera are diagnosed and a complete list of species is given. The following genera, normally classified in the family, are not included: Linstowiella Basir is considered a member of the Pharyngodonidae and perhaps a synonym of Pharyngodon Diesing; Klossinema Lal is considered a synonym of Cephalobellus Cobb; Schubartnema Kloss is considered a taxonomic chimaera, the male corresponding to Carnoya Gilson and the female probably to Binema Basir. Two new species are proposed: Gryllophila bainae and G. klossae for material assigned to G. skrjabini (Sergiev) by Bain (1965) and Kloss (1959) respectively. The following new synonyms are proposed: Blattellicola Basir and Blatellicoloides Farooqui synonyms of Blatticola Schwenck; Basiriella Ahmed & Jabin synonym of Blattophila Cobb; Leidynema (Basiria) Farooqui synonym of Cranifera Kloss; Posterovulva Van Waerebeke synonym of Desmicola Basir; Oryctophila Van Waerebeke synonym of Johnstonia Basir; Panaesthiana Kloss synonym of Leidynemella Chitwood & Chitwood; Psilocephala Rao synonym of Cameronia Basir; Welchiella Gupta & Kaur synonym of Hammerschmidtiella Chitwood. The following new combinations are proposed: Blattophila basiri for Basiriella basiri Ahmed & Jabin, leaving Blattophila basiri Farooqui pre-occupied (and renamed B. farooquii); Cameronia psilocephala and C. aspiculata for Psilocephala psilocephala Rao and P. aspiculata Farooqui respectively; Corydiella mamba (Van Waerebeke) for Thelastoma mamba; Desmicola moramangi for Posterovulva moramangi Van Waerebeke; Johnstonia morondovae for Oryctophila morondovae; Leidynemella sphaeropoei for Oxyuris sphaeropoei Parona; Thelastoma aurangabadense, T. indica (preoccupied), T. mackenziei, T. thapari, T. unicoloris and T. welchi for Schwenkiella aurangabadense Farooqui, S. indica Rao & Rao, Suifunema mackenziei Zervos, Bulhoesia thapari Singh & Singh, Cephalobellus unicoloris Van Waerebeke and Schwenkiella welchi Farooqui, respectively.     

Molecular approach to the phylogeny and systematics of Cytisus (Leguminosae) and related genera based on nucleotide sequences of nrDNA (ITS region) and cpDNA (trnL-trnF intergenic spacer)

 Phylogenetic relationships of Cytisus and allied genera (Argyrocytisus, Calicotome, Chamaecytisus, Cytisophyllum, and Spartocytisus) were assessed by analysis of sequences of the nrDNA internal transcribed spacer (ITS) and the cpDNA trnL-trnF intergenic spacer. Genera of the Genista-group (Chamaespartium, Echinospartum, Genista, Pterospartum, Spartium, Teline and Ulex) were included to check the position of Cytisus species transferred to Teline. The tree obtained by combining both sets of data indicates that the Genista and Cytisus groups form two separate clades. Cytisus heterochrous and C. tribracteolatus are more closely related to the Cytisus-group, thus their transfer to Teline is not supported by molecular data. Cytisus fontanesii (syn. Chronanthos biflorus) groups with Cytisophyllum sessilifolium and Cytisus heterochrous within the Cytisus-group. Similarly, Argyrocytisus battandieri falls within the Cytisus-group as a well differentiated taxon. All these taxa seem to have early diverged from the Cytisus-group. Their taxonomic rank should be reconsidered to better reflect their phylogenetic separation from Cytisus. On the contrary, Chamaecytisus proliferus and Spartocytisus supranubius enter in the main core of Cytisus, and they should better be included in sections of Cytisus (sect. Tubocytisus and Oreosparton, respectively). Sect. Spartopsis is not monophyletic and the position of several species, currently included in this section, deserves reevaluation: C. arboreus aggregate is closely related to C. villosus (sect. Cytisus) and to Calicotome; C. striatus is closely related to Cytisus sect. Alburnoides; and the position of C. commutatus (incl. C. ingramii) remains unclear. The relationships and positioning of several minor taxa (C. transiens, C. megalanthus, and C. maurus) are also discussed.

Food attraction and population growth of fungivorous nematodes with different fungi

Food attraction of the fungivorous nematodes Aphelenchus avenae and Aphelenchoides spp. to seven fungal species (Pyrenochaeta lycopersici, Botrytis cinerea, Rhizoctonia solani strains AG 3 and AG 2‐1, Verticillium dahliae, Pochonia bulbillosa, Mortierella hyalina and Trichoderma harzianum) was determined on agar plates by counting the number of test nematodes present on the mycelium of each fungus 24 h after inoculation. Population growth of A. avenae and Aphelenchoides spp. on five of the seven fungi included in the attraction test (P. lycopersici, R. solani strain AG 3, V. dahliae, P. bulbillosa and T. harzianum) was also determined on agar plates by counting nematode numbers every week during a 6‐week period. A. avenae and Aphelenchoides spp. were attracted to all the fungi tested. A. avenae was preferentially attracted to V. dahliae (P < 0.0001), and Aphelenchoides spp. did not show any preference except for low attraction to R. solani. A. avenae and Aphelenchoides spp. reproduced on all fungal species tested. After 6 weeks of incubation, the highest number of nematodes was found on P. lycopersici and P. bulbillosa, while the lowest number occurred on R. solani for A. avenae and on T. harzianum for Aphelenchoides spp. The suitability of a fungus as a host was not clearly related to the attraction to that fungus.     

Pollen analysis of honeys from the northwest of Argentina: Province of Jujuy

The palynological characterisation of 157 honey samples from three northwest regions of Argentina (Prepuna, Yungas and Chaco) are presented to determine their botanical origin and species associations to be able to define their geographic origin. Samples were harvested during 2003–2011 and processed by means of melissopalynological conventional techniques. One-hundred and nine pollen types were identified. Representative pollen types with a frequency of occurrence greater than 50% in descending order of importance are: Salix humboldtiana, Allophylus edulis, Baccharis, Solanaceae, Eucalyptus, Schinus, Brassicaceae, Papilionoideae, Celtis, Scutia/Condalia-type and Parapiptadenia excelsa. The most important monofloral honeys are from the following: Salix humboldtiana, Scutia/Condalia-type, Allophylus edulis, Baccharis, Blepharocalyx salicifolius, Gleditsia amorphoides, Myrtaceae, Sicyos, Ziziphus mistol, Schinopsis-type, Agonandra excelsa, Anadenathera colubrina, Mimosa, all of them native species, and among introduced species are Eucalyptus, Citrus and Tithonia. Three apicultural zones and their corresponding pollen association indicators were determined: Zone I, Prepuna: Arquita trichocarpa, Prosopis ferox, Schinus areira, Baccharis, Buddleja and Mutisieae; Zone II, Yungas: Myrtaceae, Parapiptadenia excelsa, Baccharis, Salix humboldtiana, Allophylus edulis, Scutia/Condalia-type and Zanthoxylum coco; Zone III, transitional area Yungas-Chaco: Prosopis, Salix humboldtiana, Schinus, Anadenanthera colubrina and Allophylus edulis.
