Wildlife Letters, EarlyView.Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Zhongguo youzhi, 2023 为提高茶皂苷的提取率，扩大茶皂苷的应用范围，以脱脂油茶籽饼为原料，采用超声-微波辅助法提取茶皂苷。以油茶皂苷提取率为考察指标，在单因素试验的基础上，采用Plackett-Burman试验设计筛选出具有显著影响的试验因素，再通过响应面法对茶皂苷提取工艺进行优化。另外，将超声-微波辅助法提取茶皂苷的工艺与超声辅助法和微波辅助法提取工艺进行了对比。结果表明：超声-微波辅助法提取茶皂苷的最佳工艺条件为乙醇体积分数59%、料液比1∶ 12、提取液pH 7、超声功率475 W、超声时间4 min、超声工作2 ...

Multi‐gradient warming reshapes functional traits and adaptive responses of alpine meadow plants
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional traits in alpine meadows are critical indicators of ecosystem responses to climate warming, yet dynamic changes in trait networks across warming gradients and their consequences for community functions remain poorly understood.

Housing policies and market returns in China: Evidence from a novel policy index
Real Estate Economics, EarlyView.Abstract This article examines the relationship between housing policy interventions and market returns in China with a novel policy index. Using natural language processing techniques, we construct a sentence‐level policy index based on government policy documents from 2008 to 2024.

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Role of funders in embedding tests in conservation practice
Conservation Biology, EarlyView.Abstract Effective conservation practice requires decisions based on reliable and relevant evidence, but significant gaps in the evidence base exist. Incorporating well‐designed tests of the effectiveness of interventions for biodiversity in conservation projects is one of the best ways to scale up the rate of evidence generation.
