Sclerophrys perreti is a critically endangered Nigerian native frog currently imperilled by human activities. A better understanding of its potential distribution and habitat suitability will aid in conservation; however, such knowledge is limited for S. perreti. Herein, we used a species distribution model (SDM) approach with all known occurrence data (n = 22) from our field surveys and primary literature, and environmental variable predictors (19 bioclimatic variables, elevation and land cover) to elucidate habitat suitability and impact of climate change on this species. The SDM showed that temperature and precipitation were the predictors of habitat suitability for S. perreti with precipitation seasonality as the strongest predictor of habitat suitability. The following variable also had a significant effect on habitat suitability: temperature seasonality, temperature annual range, precipitation of driest month, mean temperature of wettest quarter and isothermality. The model predicted current suitable habitat for S. perreti covering an area of 1,115 km². However, this habitat is predicted to experience 60% reduction by 2050 owing to changes in temperature and precipitation. SDM also showed that suitable habitat exists in south‐eastern range of the inselberg with predicted low impact of climate change compared to other ranges. Therefore, this study recommends improved conservation measures through collaborations and stakeholder's meeting with local farmers for the management and protection of S. perreti.

物种分布模型预测了在未来气候情景下，Sperophrys perreti的栖息地适宜性和合适栖息地的减少：一种极度濒危的尼日利亚特有蟾蜍

巩膜金枪鱼是一种濒临灭绝的尼日利亚原生青蛙，目前受到人类活动的威胁。更好地了解其潜在分布和生境适应性将有助于保护；然而，这种知识对于S.perreti是有限的。在此，我们采用物种分布模型（SDM）方法，结合了 来自田野调查和原始文献的所有已知发生数据（n = 22），以及环境变量预测因子（19个生物气候变量，海拔和土地覆盖率）来阐明栖息地的适宜性和影响气候变化对这个物种的影响。SDM表明温度和降水是S. perreti生境适宜性的预测指标降水季节是栖息地适宜性的最强预测指标。以下变量对栖息地的适应性也有重要影响：温度季节性，温度年度范围，最干旱月份的降水，最湿季的平均温度和等温度。该模型预测了S.perreti目前适合的栖息地，面积为1,115 km ²。但是，由于温度和降水的变化，预计到2050年该栖息地将减少60％。SDM还显示，在Inselberg的东南范围内存在合适的栖息地，与其他范围相比，预计气候变化的影响较小。因此，本研究建议通过与当地农民的合作和利益相关者会议以改进的保护措施，以管理和保护Per。S. perreti。
