Abstract

The determination of suitable habitats and roadkill hotspots allows for the prioritization of areas of conservation and the identification of road sections that require appropriate planning and development. Understanding the factors that influence the species’ presence and those contributing to its road-related fatalities is crucial. This study demonstrates the use of MaxEnt modeling to map the potential distribution of the striped hyaena (Hyaena hyaena) in Batna province (East Algeria) using occurrence records and a set of environmental variables. The results indicated that the two primary environmental variables that influence the distribution of the species are the shrubland, and the slope with a contribution of 37.5 and 30.2 %, respectively, followed by built-up areas (12 %) and distance to roads (7.2 %). The species may occupy steep terrain with shrubland near anthropized areas. Road collisions represent a threat to the species, with 28 documented casualties from 2010 to 2020 in Batna. The kernel density estimation revealed an important roadkill hotspot along the national roads 3 and 28. This study represents a preliminary step for the use of wildlife ecological niche modeling and road management in Algeria.

了解巴特纳（阿尔及利亚东部）条纹鬣狗的栖息地适宜性和道路死亡率，以保护条纹鬣狗

通过确定合适的栖息地和路杀热点，可以确定保护区域的优先次序，并确定需要适当规划和开发的路段。了解影响该物种存在的因素以及导致其公路死亡的因素至关重要。本研究利用 MaxEnt 建模，使用出现记录和一系列环境变量来绘制阿尔及利亚东部巴特纳省条纹鬣羚的潜在分布图。结果表明，影响该物种分布的两个主要环境变量是灌木林和坡度，分别占 37.5% 和 30.2%，其次是建筑密集区（12%）和道路距离（7.2%）。该物种可能会占据人类活动区附近的陡峭地形和灌木丛。道路碰撞对该物种构成威胁，从 2010 年到 2020 年，巴特纳有 28 起伤亡记录。核密度估计显示，3号和28号国道沿线是一个重要的路杀热点。这项研究为在阿尔及利亚使用野生动物生态位建模和道路管理迈出了第一步。

期刊介绍： Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
