Scientists’ warning on the global destruction of rock outcrop ecosystems
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

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 ...

Assessing and strengthening community‐based coastal governance
Abstract Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries

Psychometric framework for coexistence with large carnivores
Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

研究了 5种利用方式对岩溶山地土壤水稳定性团聚体的影响。结果表明 :>0 .2 5 mm水稳定性团聚体为草坡 >林地 >弃耕地 >果园 >耕地 ;林地、草坡的土壤表层和亚表层水稳定性团聚体以 >2 mm为主 ,而果园、弃耕地、耕地土壤 >2 mm的水稳定性团聚体较小。水稳定性团聚体以及团聚的水稳性均与有机质的含量呈正相关 ,林地、草坡开垦后 ,土壤有机质分解加快或补充减少是土壤团聚体水稳定性下降及数量减少的主要原因。坡耕地退耕后 ,土壤团聚体可得到恢复。

Optimizing biodiversity offsetting for habitat succession and colonization dynamics
Abstract Biodiversity offsetting aims to compensate for ecological losses from development through conservation and restoration. However, its long‐term outcomes under repeated impact–offset cycles remain uncertain. Using a conceptual forest succession model, we evaluated how offset outcomes are affected by interactions among compensation scale ...

Pollution and Haunted Eco‐Histories: Silent Hill and Silent Horrors in Centralia, Pennsylvania
ABSTRACT Centralia is a former mining town and borough in Northeastern Pennsylvania, whose population has been steadily declining since the Mine Fire of 1962—a fire that still burns today. The “horrors” of living in Centralia are reflected in horror media set in postindustrial mining towns like Silent Hill.

过去的半个多世纪,传染病模型在数学生态学领域已受广泛重视.研究了一个具时滞和扩散的传染病模型,重点讨论了该模型解的定性性质和稳态解的渐近行为;利用线性化和特征值方法讨论了正稳态解的局部稳定性,通过构造单调迭代序列,给出了正稳态解的全局稳定性.最后给出了数值模拟和讨论,当接触率充分小时,问题的无病平衡点是全局渐近稳定的.
