Abstract

内容、地点和方式:对鬃毛三趾树懒(Bradypus torquatus 和 Bradypus crinitus)栖息地丧失驱动因素的时空明确分析
了解保护状况并为保护决策提供信息的第一步是确定生境丧失的驱动因素。我们的目标是分析巴西大西洋森林中两种濒危和特有物种树懒(Bradypus torquatus 和 Bradypus crinitus)栖息地丧失的主要人为因素的时空分布。我们使用了与基于世界自然保护联盟(IUCN)的树懒所面临的七种主要威胁相关的土地利用信息,涵盖了三代人的时间窗口(1988-2020 年),以量化当前物种分布所占用的面积、时间变化、异质性以及驱动因素的强度。其他驱动因素也代表了不同物种分布中土地转换的重要时空特征。主要在牲畜扩张的驱动下,巴西大西洋森林中的两个树懒物种都经历了森林覆盖率的显著下降(Bradypus torquatus - 659098.70公顷;Bradypus crinitus - 139013.20公顷)。总体而言,Bradypus torquatus的森林砍伐率高于森林再生率,而Bradypus crinitus的森林覆盖率则高于栖息地丧失率。我们的研究结果表明,对于严格意义上的树栖物种来说至关重要的大片原始森林正不断被牧场和农业活动所取代,这可能会导致种群隔离和衰退,威胁种群的长期生存能力。

期刊介绍: Mammal Review is the official scientific periodical of the Mammal Society, and covers all aspects of mammalian biology and ecology, including behavioural ecology, biogeography, conservation, ecology, ethology, evolution, genetics, human ecology, management, morphology, and taxonomy. We publish Reviews drawing together information from various sources in the public domain for a new synthesis or analysis of mammalian biology; Predictive Reviews using quantitative models to provide insights into mammalian biology; Perspectives presenting original views on any aspect of mammalian biology; Comments in response to papers published in Mammal Review; and Short Communications describing new findings or methods in mammalian biology.
