中国华南地区多孔菌多样性研究

2002至2019年对广东、广西和海南主要森林生态系统的72个保护区、森林公园、植物园、公园和林场等的多孔菌进行了采集和调查,共采集标本2 095号,经对这些材料全面和系统的研究,发现多孔菌500种,按照最新的系统学研究分属于8个目、20个科、145个属,其中多孔菌科和锈革孔菌科分别有173种和124种,约占总数的60%,是最重要的多孔菌类群。此外,其中有10个新属和132个新种是作者等人根据华南地区模式标本发现描述的。本文对华南地区多孔菌多样性进行了系统归纳,按最新的分类系统以属名顺序给出了名录,根据采集材料提供了每种的生长基质,并对所有种类的生长基质习性进行了统计。其中,294、138、112、97、78、77和29种分别生长在倒木、落枝、朽木、死树、活立木、树桩、掉落小枝和地上,故倒木是多孔菌最重要的生长基质。     

我国寒温带至亚热带森林多孔菌区系和多样性比较

多孔菌是木材腐朽菌的重要类群, 具有重要的生态功能和经济价值。本文比较分析了我国寒温带至亚热带的阿尔泰山脉、秦岭山脉和南岭山脉的多孔菌物种、生态习性和区系特征。经调查, 在三个山脉共发现多孔菌8目29科107属287种, 其中阿尔泰山、秦岭和南岭分别为84种、132种、160种, 优势科均为多孔菌科和锈革孔菌科。三个山脉的共有属和共有种分别为25个和14个。区系地理分析发现, 阿尔泰山脉和秦岭山脉以世界广布成分和北温带成分为主, 南岭山脉以世界广布和泛热带成分为主。在寄主选择性方面, 阿尔泰山脉的多孔菌偏好生长在裸子植物上, 其比例高于被子植物, 而秦岭和南岭则相反。在腐朽类型方面, 从寒温带至亚热带白腐真菌物种数量呈现逐渐上升的趋势, 而褐腐真菌数量逐渐下降。通过比较分析3个不同气候带的多孔菌物种多样性、寄主偏好性和引起的腐朽类型, 发现气候和植被类型是影响多孔菌区系组成的主要因素。

Polypore diversity in China with an annotated checklist of Chinese polypores

This report is a comprehensive review of polypore investigations in China up to 2011. Nearly 12,000 polypore specimens have been collected from almost all forest types in China during the past 20 years. After examination of these and other herbarium specimens, 704 polypore species belonging to 132 genera in ten orders were identified, and the majority of them found to belong in the orders Polyporales (accounting for 65% of the total Chinese polypores) and Hymenochaetales (25%). According to the author’s investigations, 148 species are boreal, 390 are temperate, 395 are subtropical, and 220 are tropical in distribution. The majority of the Chinese polypores are white rot fungi, whereas 98 species (14%) cause a brown rot; 520 species (74%) were found on angiosperm wood, of which 434 species (62%) grew exclusively on angiosperm wood; 459 species (65%) were found on fallen trunks, which seem to be the most frequent substrate for polypores. Based on field investigations and collections, 223, 267, and 214 species are considered as common, occasional, and rare, respectively, and they subsequently account for 32%, 38%, and 30% of the total Chinese polypores. The host, substratum, distribution, and occurrence of each species are listed.     

大兴安岭林区多孔菌的区系组成与种群结构

本文在过去10 a野外调查和室内鉴定及分析研究的基础上,对大兴安岭林区多孔菌的区系组成和种群结构进行了分析,发现大兴安岭林区的多孔菌具有较高的多样性,共有5目11科56属129种,占中国多孔菌区系的21.36%,优势科是多孔菌科。种的区系地理成分分为7类,以北温带成分和世界广布成分为主,具有明显的北温带成分的区系特征。大兴安岭的多孔菌常见种较多,种群结构中共生菌3种,寄生菌27种,腐生菌占大多数,有99种。在能够引起木材腐朽的126种真菌中,白腐菌93种,占多数,褐腐菌33种,占少数,但该地区褐腐菌所占比例明显高于全国范围内褐腐菌在多孔菌中的比例。通过对大兴安岭主要树种上的种群结构进行比较,表明阔叶树上的木材腐朽菌绝大部分是白色腐朽菌,而针叶树上的白腐菌与褐腐菌数量相差不大,褐腐菌对于针叶林特别是落叶松的更新具有非常重要的作用。     

A tale of two clades: Comparative study of Glyptodon Owen and Glyptotherium Osborn (Xenarthra,Cingulata, Glyptodontidae)

Glyptodon and Glyptotherium represent the most conspicuous taxa of late Neogene and Pleistocene glyptodonts in South America and North America, respectively. The earliest records of Glyptodon in South America are 1.07 Ma (late early Pleistocene, Calabrian), although the possibility that “Paraglyptodon uquiensis” represents a Pliocene specimen of Glyptodon cannot be rejected. Glyptotherium originated from South American ancestry in northern South America or Central America about 3.9 Ma (early late Pliocene, Zanclean) or earlier. The diversity of South American Glyptodon is currently under study, but preliminary evidence would indicate that no more than three species (G. munizi, G. elongatus and G. reticulatus) are valid, plus a possible new Andean species. In turn, according to the updated taxonomy proposed herein, Glyptotherium includes two chronospecies. The earliest species, Gl. texanum, differs only slightly from the latest species, Gl. cylindricum. The relationship of Glyptodon and Glyptotherium has been problematical since the discovery of the North American lineage, at first identified as various species of Glyptodon and later considered a separate genus. Glyptodon is recognized as a natural group and recent taxonomic and phylogenetic revisions place all North American glyptodontines into Glyptotherium. In this paper, we propose a detailed morphological comparison between the southern South American species of Glyptodon and Glyptotherium in order to identify diagnostic differences and potential synapomorphies. Both genera can be distinguished mainly by differences in the skull, mandible, dentition, dorsal carapace, and caudal armor, Glyptodon being somewhat larger than Glyptotherium. Both clades show a highly conservative evolution, which could be interpreted as an anagenesis. The scarce records of glyptodonts in Central America show more morphological affinity with Glyptotherium than with Glyptodon.     

中国各省植物园中多孔菌种类、分布和组成

多孔菌是木材腐朽菌中最关键的真菌类群, 是森林生态系统的重要组成部分。为了明确植物园对植物上真菌资源的保护状况, 在2010-2021年间, 作者对全国31个省(自治区、直辖市)的31个代表性植物园中木本植物上的多孔菌进行了系统调查、标本采集和种类鉴定, 记录多孔菌164种, 隶属于担子菌门伞菌纲6目23科79属。其中, 中国科学院西双版纳热带植物园、儋州热带植物园和广西药用植物园多孔菌种类最多, 分别有90种、46种和37种; 兰州植物园、西宁植物园和乌鲁木齐植物园物种数量最少, 分别有4种、3种和2种。在植物园中, 分布最多的物种是云芝栓孔菌(Trametes versicolor)、白囊耙齿菌(Irpex lacteus)和黑管孔菌(Bjerkandera adusta), 分别生长在24、18和18个植物园中, 而软多孢孔菌(Abundisporus mollissimus)等32种多孔菌只发现于中国科学院西双版纳热带植物园中。在164种多孔菌中, 常见种、偶见种和稀有种分别有114、40和10种。生长在植物园中的多孔菌仅占全国所有森林生态系统多孔菌总数的16%, 而植物园中发现的稀有种仅占全国稀有种总数的3.1%。在10种稀有多孔菌中, 有6种发现于中国科学院西双版纳热带植物园的天然林中, 其中4种稀有多孔菌发现于植物园内的人工林中, 占植物园所有多孔菌的2.4%, 占全国稀有多孔菌的1.3%。所调查植物园多孔菌包括了热带、亚热带、温带、北半球广布和寒温带成分, 分别包括50、45、38、20和11种, 占本研究多孔菌总数的30.5%、27.4%、23.2%、12.2%和6.7%。目前中国植物园保存了我国60%的植物种类, 包括85%的珍稀濒危植物, 但对生长在植物园中的多孔菌资源保护作用有限。因此, 对稀有多孔菌的保育仍需聚焦在森林生态系统的保护上。     

东喜马拉雅地区多孔菌区系和生态习性

对东喜马拉雅地区多孔菌区系和生态习性进行了分析,发现该地区多孔菌极为丰富,共有10目19科101属372种,其中优势科为多孔菌科和锈革孔菌科,优势属为木层孔菌属和多孔菌属。种的区系地理成分可以分为8类,其中北温带类型种类最多,表明东喜马拉雅地区多孔菌具有明显的北温带区系特征。该地区的多孔菌有常见种、偶见种、稀有种和濒危种分别为156、141、54和21个;有腐生菌304种、寄生菌49种、菌根菌19种。在寄主方面,能够生长在被子植物上的有256种,裸子植物上的有137种,既能生长在被子植物,也能生长在裸子植物上的有40种,地上生长的有19种。东喜马拉雅地区的裸子植物,特别是云杉属、松属和冷杉属树木对于多孔菌的生长更重要,因为生长在这些属树木上的多孔菌分别有71、68和51种,高于该地区被子植物其他属树木上的多孔菌。     

我国西北和东南地区多孔菌种群差异

多孔菌是木材腐朽真菌中对木材降解发挥作用最大、种类最多的一个类群,对森林中营养物质的循环具有极为重要的作用.本文对北起天山、祁连山、宝天曼,南至武夷山的4个不同地点的多孔菌物种组成和区系进行了比较分析.调查发现,天山地区具有多孔菌种类72种,祁连山为99种,宝天曼为124种,武夷山为156种.这4个地区的共有物种为14种.上述地区多孔菌的属地理成分均以世界广布和北温带分布为主,具有明显的北温带成分区系特征.比较木材降解方式发现,白腐菌种类在各地区所占物种比例由北到南呈上升趋势,褐腐菌的比例总体呈下降趋势.生长在被子植物上的多孔菌种类在宝天曼地区所占比例最多.天山和祁连山地区的稀有种和濒危种主要生长在针叶树上,宝天曼和武夷山则主要生长在阔叶树上.从4个地区多孔菌的多样性、基质选择和降解方式差异来看,森林植被类型在其中起到很大的作用.     

Annotated checklist of the living sharks,batoids and chimaeras (Chondrichthyes) of the world,with a focus on biogeographical diversity

An annotated checklist of the chondrichthyan fishes (sharks, batoids and chimaeras) of the world is presented. As of 7 November 2015, the number of species totals 1188, comprising 16 orders, 61 families and 199 genera. The checklist includes nine orders, 34 families, 105 genera and 509 species of sharks; six orders, 24 families, 88 genera and 630 species of batoids (skates and rays); one order, three families, six genera and 49 species of holocephalans (chimaeras). The most speciose shark orders are the Carcharhiniformes with 284 species, followed by the Squaliformes with 119. The most species‐rich batoid orders are the Rajiformes with 285 species and the Myliobatiformes with 210. This checklist represents the first global checklist of chondrichthyans to include information on maximum size, geographic and depth distributions, as well as comments on taxonomically problematic species and recent and regularly overlooked synonymizations. Furthermore, a detailed analysis of the biogeographical diversity of the species across 10 major areas of occurrence is given, including updated figures for previously published hotspots of chondrichthyan biodiversity, providing the detailed numbers of chondrichthyan species per major area, and revealing centres of distribution for several taxa     

Recognizing ecological patterns of wood-decaying polypores on gymnosperm and angiosperm trees in northeast China

Wood-decaying polypores are macrofungi with the capacity to decompose lignocellulose, and hence play essential roles in forest ecosystems. Host (tree species) range and preference are among the most important factors influencing polypore communities. Here, we studied polypore ecological patterns between gymnosperm and angiosperm trees based on data collected from more than 10 yr field investigations in Fenglin and Changbaishan Nature Reserve, northeast China (boreal and temperate zone). Although species richness was similar between the polypores associated with the two tree groups, gymnosperm trees showed: (1) a higher similarity in polypores species; (2) a lower polypore species richness on fallen trunks; (3) a lower polypore species richness in unprotected forests; (4) fewer common polypores but more occasional species; (5) a lower proportion of white rot but a higher proportion of brown rot polypores. In general, our findings supported previous views that different preferences between gymnosperm and angiosperm trees in polypores are probably caused by different structure and content of lignins between the two tree groups.

Extended phylogeny of Aquilegia: the biogeographical and ecological patterns of two simultaneous but contrasting radiations

Studies of the North American columbines (Aquilegia, Ranunculaceae) have supported the view that adaptive radiations in animal-pollinated plants proceed through pollinator specialisation and floral differentiation. However, although the diversity of pollinators and floral morphology is much lower in Europe and Asia than in North America, the number of columbine species is similar in the three continents. This supports the hypothesis that habitat and pollinator specialisation have contributed differently to the radiation of columbines in different continents. To establish the basic background to test this hypothesis, we expanded the molecular phylogeny of the genus to include a representative set of species from each continent. Our results suggest that the diversity of the genus is the result of two independent events of radiation, one involving Asiatic and North American species and the other involving Asiatic and European species. The ancestors of both lineages probably occupied the mountains of south-central Siberia. North American and European columbines are monophyletic within their respective lineages. The genus originated between 6.18 and 6.57 million years (Myr) ago, with the main pulses of diversification starting around 3 Myr ago both in Europe (1.25–3.96 Myr ago) and North America (1.42–5.01 Myr ago). The type of habitat occupied shifted more often in the Euroasiatic lineage, while pollination vectors shifted more often in the Asiatic-North American lineage. Moreover, while allopatric speciation predominated in the European lineage, sympatric speciation acted in the North American one. In conclusion, the radiation of columbines in Europe and North America involved similar rates of diversification and took place simultaneously and independently. However, the ecological drivers of radiation were different: geographic isolation and shifts in habitat use were more important in Europe while reproductive isolation linked to shifts in pollinator specialisation additionally acted in North America.     

Taxonomic diversity of the terrestrial bird and mammal fauna in temperate and boreal biomes of the northern hemisphere

Abstract. Using comprehensive range information of northern Hemisphere birds and mammals, we assessed the taxonomic diversity of these two groups in four different regions: Europe, east Asia, and western and eastern North America. East Asia is the richest region in the number of bird and mammal species, genera, families and orders, except that mammal species richness is highest in western North America. Eastern North America is taxonomically the poorest region, but when only forest-associated taxa were considered in mammals taxonomic diversity is equally low in Europe and in eastern North America, and in birds, Europe is the least diverse region. Patterns in endemic taxa follow overall taxonomic diversity. The proportion of shared taxa between regions is higher among boreal species and genera than among all taxa. A comparison with tree species diversity underpins the role of east Asia as the most diverse of all northern biota. Largely congruent patterns at different taxonomic levels emphasizes the role of historical processes, such as differential extinction rate in response to paleoenvironmental fluctuations, in producing these patterns, but we stress the need for more research on the coevolution of species diversity and habitat diversity.     

福建苔类和角苔类植物最新名录与区系分析

福建地处亚热带,其维管植物多样性已经有过广泛的研究,但其苔类和角苔类植物的多样性却鲜为人知。在本研究中,作者基于先前的苔藓植物文献报道和近期的野外工作以及对华东师范大学标本馆部分馆藏标本的研究结果,编写了福建苔类和角苔类植物的最新名录。福建共有苔类植物41科79属351种,角苔类植物1科4属6种。本研究新增福建苔类新记录82种。福建苔类和角苔类植物区系主要由细鳞苔科（94种）,耳叶苔科（32种）,羽苔科（25种）,扁萼苔科（23种）和指叶苔科（21种）等一些热带和亚热带的大科组成。除种数较多的属以外,63个属的种数不足5种,其中包括33个单种属。福建苔类和角苔类植物的区系地理分布主要以东亚、热带亚洲和北温带成分为主。福建特有种仅Solenostoma parviperianthum一种。与台湾相比,尽管两地植物间具有较高的相似性,福建在苔类和角苔类植物的多样性以及特有成分上都还远不及台湾丰富。     

Comments on the gonotyl of Proctocaecum macroclemidis (Tkach and Snyder, 2003) n. comb. (Digenea: Acanthostomidae: Acanthostominae), with a key to the genera of acanthostominae and new phylogenetic tree for Proctocaecum Baugh, 1957

The species recently described as Acanthostomum macroclemidis possesses the gonotyl in the form of a solid muscular pad uniquely diagnostic for species of Proctocaecum and is accordingly transferred to that genus. An artificial key to the 5 acanthostomine genera, as well as an updated phylogenetic hypothesis for the 10 known species of Proctocaecum, based on 11 characters and including 2 species described since the last phylogenetic analysis, are presented. The single most parsimonious phylogenetic tree with a consistency index of 87.5% suggests that Proctocaecum originated in Africa and spread to North America and South America before the breakup of Pangaea. As a result, the 2 North American and 1 South American species are most closely related to different African members of the genus. African and Indo-Pacific species inhabit crocodylids; hence, the occurrence of North American species in alligatorids and chelonians and a South American species in alligatorids are the result of host switches.     

Phylogeny of North American amblemines (Bivalvia, Unionoida): prodigious polyphyly proves pervasive across genera

Abstract. The subfamily Ambleminae is the most diverse subfamily of fresh‐water mussels (order Unionoida), a globally diverse and ecologically prominent group of bivalves. About 250 amblemine species occur in North America; however, this diversity is highly imperiled, with the majority of species at risk. Assessing and protecting this diversity has been hampered by the uncertain systematics of this group. This study sought to provide an improved phylogenetic framework for the Ambleminae. Currently, 37 North American genera are recognized in Ambleminae. Previous phylogenetic studies of amblemines highlighted the need for more extensive sampling due to the uncertainties arising from polyphyly of many currently recognized taxa. The present study incorporated all amblemine genera occurring in North America north of the Rio Grande, with multiple species of most genera, including the type species for all but seven genera. A total of 192 new DNA sequences were obtained for three mitochondrial gene regions: COI, 16S, and ND1. In combination with published data, this produced a data matrix incorporating 357 gene sequences for 143 operational taxonomic units, representing 107 currently recognized species. Inclusion of published data provides additional taxa and a summary of present molecular evidence on amblemine phylogeny, if at the cost of increasing the amount of missing data. Parsimony and Bayesian analyses suggest that most amblemine genera, as currently defined, are polyphyletic. At higher taxonomic levels, the tribes Quadrulini, Lampsilini, and Pleurobemini were supported; the extent of Amblemini and the relationships of some genera previously assigned to that tribe remain unclear. The eastern North American amblemines appear monophyletic. Gonidea and some Eurasian taxa place as probable sister taxa for the eastern North American Ambleminae. The results also highlight problematic taxa of particular interest for further work.
