The collective application of shorebird tracking data to conservation
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

提出一种基于三参数Burr分布的估计方法来描述零值悬瓷绝缘子的温度分布特性。为验证这一方法,以某省电网运行10年及以上变电站悬式绝缘子红外测零项目的红外测温数据为研究对象,通过统计分析建立了三参数Burr分布数学模型。由于该分布函数的参数在极大似然估计法下没有显式解,故采用牛顿法对其求解,可得到三参数Burr分布对绝缘子零值温差分布的拟合曲线;然后,在MATLAB中利用Kolmogorov-Smirnov方法对于该分布模型进行了参数检验。检验结果表明 ...

Comprehensive framework for assessing and optimizing existing research networks
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

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 ...

Although å§å§ /jiejie/ (“elder sister”) and 妹妹 /meimei/ (“younger sister”) are basic relatives' terms of the nuclear and consanguinity kinship, they mean a big challenge when they are translated into Spanish because of the linguistic and cultural differences and defaults between the Chinese and the Spanish.

Emerging applications of large language models in ecology and conservation science
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

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 ...
