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

Quercus relative to the other species under high light and limited water, for Arbutus under high light and water availability, and for C

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.

30 million, of which 52% was
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 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. 相似文献

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. 相似文献

Comparative studies of the genera Hesionides and Microphthalmus have produced a lot of results to anatomy, ecology, life history, locomotion and systematics (3 new species) of polychaetes. The small shape of the body, adhesive anal lobes, neuropods working like legs, aberrant complicated sexual organs, shape of the sperms, formation of spermatophores, development in cocoons, seasonal migrations etc. are considered as adaptations to the extreme environmental factors of sandy biotopes.

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. 相似文献

Roots of 40 taxa of higher plants (Pteridophyta, Spermatophyta) from two alpine study sites in Denali National Park and Preserve
in central Alaska were examined for their mycorrhizal colonization. We observed ectomycorrhizae on six species: Betula
nana, Salix
reticulata, Salix
polaris, Salix
arctica, Polygonum
viviparum, and Dryas
octopetala. Seven taxa, Cassiope
tetragona, Empetrum
nigrum, Ledum
palustre subsp. decumbens, Ledum
palustre subsp. groenlandicum, Loiseleuria
procumbens, Vaccinium
uliginosum and Vaccinium
vitis–idaea (all Ericales), had ericoid mycorrhizae. One species, Arctostaphylos
alpina, formed a typical arbutoid mycorrhiza. Two species (Sibbaldia
procumbens and Aconitum
delphinifolium) showed well-developed VA mycorrhizae, whereas three species of plants (Lycopodium
clavatum, Silene
acaulis and Oxytropis
scammaniana) had vesicles, but no arbuscules. The roots of 11 other plants (Lycopodium
clavatum, Lycopodium
selago, Silene
acaulis, Gentiana
algida, Lupinus
arcticus, Oxytropis
scammaniana, Pedicularis
langsdorffii, Pedicularis
capitata, Pedicularis
verticillata, Artemisia sp. and Carex
bigelowii) had a variety of intracellular colonizations which are referred to as dark septate fungi. No mycorrhizae were found on 12
other plants: Equisetum
arvense, Equisetum
variegatum, Lycopodium
alpinum, Polygonum
bistorta, Saxifraga
hieracifolia, Saxifraga
hirculus, Astragalus
alpinus, Pedicularis
kanei, Petasites
frigidus, Carex
podocarpa, Carex
microchaeta and Poa
arctica. A possible ecological role of dark septate fungi is discussed.

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. 相似文献

Using flow cytometry in fresh plants and herbarium vouchers, DNA ploidy levels for 411 individuals of 44 taxa of the genus
Festuca, including 4 natural hybrids, originating from 237 sites in Austria, Bulgaria, Croatia, Czech Republic, Estonia, Germany,
Hungary, Italy, Poland, Romania, Slovakia, Slovenia, and Switzerland were estimated. The following taxa and DNA ploidy levels
are reported: F. airoides (2n ≈ 2x), F. alpestris (2n ≈ 2x), F. alpina s.l. (2n ≈ 2x), F. amethystina subsp. amethystina (2n ≈ 4x), F. bosniaca subsp. bosniaca (2n ≈ 2x), F. brevipila (2n ≈ 6x), F. bucegiensis (2n ≈ 2x), F. carnuntina (2n ≈ 6x), F. csikhegyensis (2n ≈ 4x), F. csikhegyensis × F. eggleri (2n ≈ 4x), F. dalmatica (2n ≈ 4x), F. duvalii (2n ≈ 4x), F. eggleri (2n ≈ 2x, 4x), F. filiformis (2n ≈ 2x), F. glauca (2n ≈ 6x), F. heterophylla (2n ≈ 4x), F. inops (2n ≈ 2x), F. laevigata (2n ≈ 8x), F. laxa (2n ≈ 4x), F. lemanii (2n ≈ 6x), F. norica (2n ≈ 2x), F. ovina subsp. ovina (2n ≈ 2x), F. ovina subsp. guesfalica (2n ≈ 4x), F. ovina × F. pallens (2n ≈ 4x), F. pallens (2n ≈ 2x, 3x), F. pallens × F. pseudodalmatica (2n ≈ 3x, 4x), F. pirinica (2n ≈ 2x), F. polesica (2n ≈ 2x), F. psammophila subsp. dominii (2n ≈ 2x), F. pseudodalmatica (2n ≈ 4x), F. pseudovina (2n ≈ 2x), F. quadriflora (2n ≈ 4x), F. rupicola (2n ≈ 6x), F. rupicola × F. vaginata (2n ≈ 3x, 4x), F. saxatilis (2n ≈ 6x), F. stricta subsp. bauzanina (2n ≈ 8x), F. supina (2n ≈ 4x), F. tatrae (2n ≈ 2x), F. valesiaca (2n ≈ 2x), F. versicolor subsp. pallidula (2n ≈ 2x), F. versicolor subsp. versicolor (2n ≈ 2x), F. violacea subsp. puccinellii (2n ≈ 2x), F. wagneri (2n ≈ 4x), F. xanthina (2n ≈ 2x). In F. pallens, up to 12-year-old herbarium specimens were proved to be suitable for DNA ploidy level measurements with flow cytometry.
DNA ploidy levels of F. bucegiensis, F. bosniaca, and F. versicolor subsp. pallidula are reported here for the first time. The taxonomy of some polyploid complexes and several records of mixed ploidy level
populations are briefly discussed. Festuca pseudodalmatica and its hybrid F. × krizoviensis were first recognised as native to the Czech Republic, and F. brevipila as native to Hungary. Also some new records of F. filiformis, F. brevipila, and F. wagneri from Slovakia are reported. 相似文献

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. 相似文献

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.

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 .

Work on the exceptionally well-preserved, rapidly accumulating Bath Cliff Section, Barbados and supplementary Deep Sea Drilling Project samples, has revealed the evolutionary origins of three stratigraphically useful species in theCryptoprora ornata Zone straddling the Eocene/Oligocene boundary and demonstrated the origin of the genusCyclampterium. Elucidation of the origin ofCyclampterium milowi necessitates a revision of the generaLophocyrtis andCyclampterium.Lophocyrtis (Lophocyrtis)jacchia is the ancestor ofL. (Cyclampterium)hadra, the earliest member in the subgenusCyclampterium which comprises the anagenetic lineage leading fromL. (C.)hadra toL. (C.)neatum. The monotypic subgenusSciadiopeplus branches off from an early member in theCyclampterium lineage. The new speciesL. (L.)exitelus andL. (S.)oberhaensliae terminate the subgeneraLophocyrtis andSciadiopeplus, respectively. During the investigation it also became clear that morphotypes resembling earlyL. (C.)milowi could be found in mid and high latitude assemblages in the late Early and late Middle Eocene. The origin of one these morphotypes was also traced toL. (Lophocyrtis)jacchia giving rise to the new subgenusParalampterium. This lineage includes the new speciesL. (Paralampterium)dumitricai and two species questionably assigned to it,L. (Paralampterium)?longiventer and the new speciesL. (Paralampterium) ?galenum. The relationship ofL. (P.)dumitricai toL. (P.) ?longiventer andL. (P.) ?galenum is unknown. 相似文献
