Three new species of Phomopsis causing leaf spots on multiple hosts in Gutianshan Nature Reserve are characterized and illustrated. Phylogenetic analyses and morphological characteristics are employed to justify the introduction of the new species. The phylogenetic relationships of the three new species were inferred by analyses based on combined rDNA-internal transcribed spacer (ITS) and partial translation elongation factor 1-alpha (TEF1) gene regions. Comparisons are made with morphologically similar and phylogenetically closely related species. 相似文献

Five new species of the Boletaceae (Agaricales) from Japan are described and illustrated: (1) Boletus bannaensis sp. nov. (section Luridi), forming a grayish-brown pileus and rufescent flesh, found in subtropical evergreen broad-leaved forests; (2) Leccinum rhodoporosum sp. nov., forming discolorous red pores, a whitish stipe covered overall with violet-brown to blackish-brown furfuraceous
scales and fusoid-cylindrical brown basidiospores, found in subtropical evergreen broad-leaved forests or warm-temperate Quercus-Pinus forests; (3) Pulveroboletus brunneoscabrosus sp. nov., forming a lemon-yellow pulverulent basidiomata covered overall with orange to brownish-orange appressed scales,
found in subtropical to warm temperate evergreen broad-leaved forests; (4) Rubinoboletus monstrosus sp. nov., forming a brownish-orange to yellowish-brown pileus and a very short, nonreticulate, hollow stipe, found in subtropical
evergreen broad-leaved forests; and (5) Tylopilus fuligineoviolaceus sp. nov., having a deep violet to blackish-brown pileus and brunnescent hymenophore, found in warm temperate Quercus-Castanopsis forests. 相似文献

Bitahai Nature Reserve is located in Northwest Yunnan and is the highest elevation and the highest latitude wetland nature reserve in Yunnan Province. Bitahai Nature Reserve is a typical wetland nature reserve in very low latitude and high elevation with large areas of coniferous forest around the alpine till lakes, wetland and water area ecosystem while compared with natural reserves distributed same latitude in the world. The area of the reserve distribution is the key area of Transverse Mountain Region. It was a refuge for plant and wildlife because Transverse Mountains were not covered by ice in the Tertiary. And the area is now regarded as a center of forming new species and preserving ancient species. Species biodiversity is high and the distribution of some endemic animals and plants are limited in Transverse Mountains area. In the nature reserve, there are many first and second grade protected plants and animals listed in Lists of China National Priority Protection Fauna and Flora. All of these are precious materials of genetic diversity. The diversities of the plant community and vegetation contribute to ecosystem diversity. Thus, Bitahai Nature Reserve holds with high conservation value. However, its biodiversity is threatened by different factors and its conservation should be paid great attention. 相似文献

目的了解广东象头山国家级自然保护区蛇类多样性现状,探讨保护区蛇类资源的有效保护对策。方法采用访问调查和野外样带调查相结合的方法。结果该保护区现已纪录蛇类有5科45种,占中国已纪录蛇类物种数的22.0%,占广东省已纪录蛇类物种数的46.4%,区系组成以东洋界华中区和华南区共有种为主,占82.2%。保护区有国家Ⅰ级重点保护野生动物蚺双带亚种(蟒蛇)(Python molurus bivittatus),以及舟山眼镜蛇(Najaatra)、眼镜王蛇(Ophiophagus hannah)、灰鼠蛇(Ptyas korros)和滑鼠蛇(Ptyas mucosus)等15种重要经济蛇类。结论广东象头山国家级自然保护区蛇类物种多样性十分丰富,但长期过度猎捕和栖息地遭破坏导致保护区一些蛇类种群数量明显减少,需加强保护。本文针对保护区蛇类保护问题提出5点建议。 相似文献

2006~2011年采用野外调查和访问调查相结合的方法,对广东鼎湖山国家级自然保护区爬行动物进行了专项调查研究。迄今,该保护区已记录爬行动物2目12科54种,其中6种为本次调查发现的新纪录,分别是截趾虎Gehyra mutilata、丽棘蜥Acanthosaura lepidogaster、棕黑腹链蛇Amphiesma sauteri、黑领剑蛇Sibynophis collaris、细白环蛇Lycodon subcinctus和乌龟Mauremys reevesii。本次调查野外发现爬行动物共38种,其中包括珍稀濒危物种平胸龟Platysternon megacephalum,16种文献有记载的爬行动物在本次调查中未发现。访问调查发现6只四眼斑水龟Sacalia quadriocellata,很可能来自鼎湖山。基于调查结果,对该保护区爬行动物多样性及受胁因素进行了探讨,并提出了4点保护管理建议。 相似文献

A new freshwater goby, Rhinogobius wangi, was collected from a small tributary of the Hanjiang Basin, Guangdong Province, southeastern China. The species can be distinguished
from all congeneric species by the following unique combination of features: second dorsal fin rays I, 8; anal fin rays I,
7; pectoral fin rays 16; rather large scales as longitudinal scale series 26–27; predorsal scales 8–9; vertebral count 10 + 17 = 27;
seven parallel, deep brown oblique stripes crossing on cheek in male; branchiostegal membrane with brownish-red spots in male;
seven longitudinal deep brown lines on lateral side of body; pectoral fin base with a blackish-brown bar. A key to all nominal
species with high vertebral counts from China (Hanjiang to Chiangtangjiang basins), Taiwan, and Japan is also provided. 相似文献
