Abstract Pleurodeles poireti is one of the lesser-known amphibians in the Mediterranean region. This species is strictly endemic to the Edough Peninsula in northeastern Algeria. Here we investigated the factors that determine the presence of P. poireti, by affecting its selection of both aquatic and terrestrial habitats. Aquatic habitats were characterised according to their morphology and the physicochemical parameters of the water. We also examined the topographical and substrate features, plant cover and climatic conditions at the occurrence sites. Our surveys indicated that P. poireti is widely-distributed on the Edough Peninsula. Pleurodeles poireti predominantly breeds in moderate to large water bodies densely covered with emergent vegetation. The water parameters are less influential in its selection of breeding sites, except dissolved oxygen and turbidity, which are usually high at the occupied sites. At the broad spatial scale, P. poireti is positively associated with lowlands in cultivated landscapes. However, the species has a relatively broad niche in the region, and also occurs in cork oak forests. The species tolerates some level of human alteration of the landscape, but some populations close to villages could disappear in response to the combined effects of habitat destruction and the presence of alien fish.

决定阿尔及利亚东北部埃多半岛 Poireti poireti（尾目：蝾螈科）发生的因素

摘要 Pleurodeles poireti 是地中海地区鲜为人知的两栖动物之一。该物种是阿尔及利亚东北部埃多半岛的特有种。在这里，我们调查了决定 P. poireti 存在的因素，通过影响其对水生和陆地栖息地的选择。水生栖息地根据其形态和水的物理化学参数进行表征。我们还检查了发生地点的地形和基质特征、植物覆盖和气候条件。我们的调查表明 P. poireti 广泛分布于 Edough 半岛。Pleurodeles poireti 主要在被新兴植被覆盖的中等至大型水体中繁殖。水参数对其繁殖地点的选择影响较小，除了溶解氧和浊度，它们在占用的场地通常很高。在广阔的空间尺度上，P. poireti 与耕地景观中的低地呈正相关。然而，该物种在该地区拥有相对广泛的生态位，也出现在软木橡树林中。该物种可以容忍一定程度的人类对景观的改变，但由于栖息地破坏和外来鱼类存在的综合影响，靠近村庄的一些种群可能会消失。
