摘要
对于出现在多用途景观中的濒危物种来说,协调的跨权属管理方法是实现长期保护成果的理想选择。为了全面了解西澳大利亚(WA)皮尔巴拉(Pilbara)地区大叶狸(Macrotis lagotis)保护优先事项的进展情况,并为正在进行的研究和资金投入提供信息,我们回顾了过去十年中以该物种为重点的研究计划。2013年的利益相关者研讨会初步确定了研究重点,针对关键领域的研究极大地提高了人们对皮尔巴拉和西澳大利亚其他地区山熊的生态认识。研究重点包括:开发基于 DNA 的非侵入性粪便丰度监测技术;进一步了解栖息地的使用和饮食,包括寄生在根部的幼虫的金合欢属植物的重要性;以及引入的捕食者带来的威胁。拟议的未来研究方向侧重于更好地了解栖息地要求和主要食物资源与火灾之间的关系,评估景观尺度上的遗传结构和基因流,以及研究威胁之间的相互作用。建议进行管理以减轻一系列威胁,包括引入的捕食者、放牧牲畜/野生食草动物和火灾,并考虑采用综合方法。
Informing conservation management of the bilby (Macrotis lagotis) in the Pilbara: a review of research and future directions
For threatened species that occur across multi-use landscapes, a coordinated cross-tenure management approach is desirable to achieve long-term conservation outcomes. To provide a comprehensive understanding of the progress towards achieving conservation priorities for the greater bilby (Macrotis lagotis) in the Pilbara region of Western Australia (WA), and inform ongoing research and funding investment, we review a research program that has focused on the species over the past decade. Priorities were initially established at a stakeholder workshop in 2013, and research targeting key areas has greatly enhanced ecological knowledge of the bilby in the Pilbara and elsewhere in WA. Highlights include the development of a non-invasive scat DNA-based abundance monitoring technique, an improved understanding of habitat use and diet, including the importance of Acacia spp. that host root-dwelling larvae, and the threat posed by introduced predators. Proposed future research directions focus on better understanding habitat requirements and the association between key food resources and fire, evaluating genetic structure and gene flow at the landscape-scale and examining threat interactions. Management to mitigate a range of threats including introduced predators, grazing livestock/feral herbivores and fire is recommended, with consideration for an integrated approach.
期刊介绍:
Australian Mammalogy is a major journal for the publication of research in all branches of mammalogy. The journal’s emphasis is on studies relating to Australasian mammals, both native and introduced, and includes marine mammals in the Antarctic region. Subject areas include, but are not limited to: anatomy, behaviour, developmental biology, ecology, evolution, genetics, molecular biology, parasites and diseases of mammals, physiology, reproductive biology, systematics and taxonomy.
Australian Mammalogy is for professional mammalogists, research scientists, resource managers, consulting ecologists, students and amateurs interested in any aspects of the biology and management of mammals.
Australian Mammalogy began publication in 1972 and is published on behalf of the Australian Mammal Society.
