RUI: Fungi and their Associated Mycophagous Beetle Biodiversity on Subantarctic Campbell Island

斯蒂芬森9971695关于真菌及其相关生物在特定类型的陆地生态系统中的组合以及它们在这些生态系统中发挥的基本生态作用的大部分已知知识，都来自于在世界温带地区进行的研究。对于这两类生物在世界上以寒冷为主的高纬度地区的生物多样性和生态学，人们知之甚少。拟议研究的目的是对与坎贝尔岛各种生境有关的真菌和甲虫进行首次深入研究。坎贝尔岛是一个海洋小岛，位于新西兰大陆以南约700公里。主要重点将放在评估食真菌甲虫和陆地真菌四个主要分类类群的分布模式、相对丰度、宿主/底物关联和生态作用上。次要的重点将放在地衣真菌和在岛上的小溪和湖泊中发现的各种水生真菌上。坎贝尔岛上真菌和甲虫聚集的数据将与南极地区的另外两个岛屿(麦夸里岛和南乔治亚岛)以及北极地区的类似地区(包括阿拉斯加阿留申群岛)现有的类似数据进行比较。

Stephenson9971695Most of what is known about the assemblages of fungi and their associated beeltes in particular types of terrestrial ecosystems and the fundamental ecological roles that they play in these ecosystems has been derived from studies carried out in temperate regions of the world. Relatively little is konwn about the biodiversity and ecology of these two groups of organisms in cold-dominated, high-latitude regions of the world. The objective of the proposed research is to carry out the first intensive study of the fungi and beetles associated with various habitats on Campbell Island, a small oceanic island located approximately 700 km south of the New Zealand mainland. Primary emphasis will be directed towards assessing patterns of distribution, relative abundance, host/substrate associations and ecological roles for mycophagous beetles and four major taxonomic groups of terrestrial fungi. Secondary emphasis will be placed on lichenized fungi and the various groups of aquatic fungi found in the small streams and lakes that occur on the island. Data obtained for the assemblages of fungi and beetles on Campbell Island will be compared with similar data that already exist for two other islands (Macquarie Island and South Georgia Island) in the south polar region and comparable areas of the north polar region, including the Alaskan Aleutian Islands.
