Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Taxonomic and functional diversity of urban bees of the world
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

海南溪树蛙(Buergeria oxycephala)是中国特有种,处于近危状态,仅分布于海南岛,预测海南溪树蛙潜在适生区可为物种保护与研究提供重要参考。依据该蛙68个物种位点数据和9个环境因子,利用最大熵模型(MaxEnt)与地理信息系统(GIS),对其在海南岛的潜在适生区进行预测,并通过刀切法和单一环境因子的响应曲线分析其与环境因子之间的关系。结果表明:海拔、气温季节性变化、坡度和气温年较差这4个因子对模型增益效果最为明显。海南溪树蛙适生区的最佳环境因子范围,海拔430—1200 m ...

Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...

Mistimed surveys lead to underestimated migratory bird impacts from wind farms
Current guidance and approaches to surveying migratory birds at windfarm developments in Australia are insufficient. Evidence‐based alignment with seasonal presence is needed to improve biodiversity assessment standards, ensuring renewable energy expansion proceeds in a way that better safeguards migratory species and supports global biodiversity and ...

生态位适宜度是对经典生态位理论和方法的深化与发展,在合理优化利用环境资源,发挥作物、环境最大共生效应,及工农业布局和指导农业生产中具有重要的实际意义。在可持续发展理论的指导下,以江汉平原后湖地区耕地为研究对象,将生态位适宜度模型引入到多宜性评价研究中,采用加权平均和限制因子模型对各评价单元水稻、油菜、小麦和棉花4种作物的生态位适宜度进行了定量分析。结果表明:研究区生态位适宜度值整体较高,生境条件基本能满足作物的需求;部分地块的生境条件需要改善;限制该地区土地生产潜力的生态因子主要为:CEC,速效磷和全氮。
