Environmental determinants of mass extinctions by emerging disease: why does chytridiomycosis exterminate frogs in rainforest but not in open forest?

这种新出现的真菌疾病被称为合并孢菌病，正在导致世界各地许多种青蛙的衰落和灭绝；澳大利亚也不例外。尽管目前已经制定了减少威胁的计划，但在野外处理这一问题的成功管理战略并不存在。在昆士兰北部潮湿的热带地区，健康的激流蛙种群存在于雨林附近较干燥的地区，它们在那里消失了。了解它们是如何与这种病原体共存的，以及它们重新定居雨林的传播能力，是帮助这些物种在未来的保护工作中所必需的基本信息。

The emerging fungal disease known as chytridiomycosis is causing decline and extinctions of many species of frogs around the world; Australia is no exception. Although a threat abatement plan is currently in place, a successful management strategy to deal with this problem in the wild does not exist. In the wet tropics region of north Queensland, healthy populations of torrent frogs exist in the drier areas adjacent to the rainforest where they disappeared. Understanding how they coexist with this pathogen, as well as their dispersal capacity to recolonise the rainforest is basic information necessary to aid theses species in future conservation efforts.
