Abstract

The common impala (Aepyceros melampus melampus), a medium-sized herbivore in Eastern and Southern African savannahs, faces challenges from climate change. Using a species distribution model, we found temperature of the driest quarter (30.32%) and wettest month precipitation (20.36%) as the most influential factors. Surprisingly, land cover change had less impact (0.25%). Projections suggest a significant habitat reduction for impalas by 2050, with estimated losses of 18.12% (SSP-126) and 25.62% (SSP-585). These findings highlight climate change and land cover alterations as potential threats to impala survival, impacting crucial resources like forage and water. This research guides conservation efforts for common impala.

模拟普通黑斑羚（Aepyceros melampus melampus）在非洲不断变化的气候中的潜在分布情况

黑斑羚（Aepyceros melampus melampus）是非洲东部和南部稀树草原上的一种中型食草动物，它面临着气候变化带来的挑战。利用物种分布模型，我们发现最干旱季度的温度（30.32%）和最潮湿月份的降水（20.36%）是影响最大的因素。令人惊讶的是，土地覆盖变化的影响较小（0.25%）。预测表明，到 2050 年，黑斑羚的栖息地将大幅减少，估计损失率为 18.12%（SSP-126）和 25.62%（SSP-585）。这些研究结果突出表明，气候变化和土地植被的改变是黑斑羚生存的潜在威胁，会影响到饲料和水等重要资源。这项研究为黑斑羚的保护工作提供了指导。

期刊介绍： African Journal of Ecology (formerly East African Wildlife Journal) publishes original scientific research into the ecology and conservation of the animals and plants of Africa. It has a wide circulation both within and outside Africa and is the foremost research journal on the ecology of the continent. In addition to original articles, the Journal publishes comprehensive reviews on topical subjects and brief communications of preliminary results.
