Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

This study investigates distribution patterns of Galliforms in the Indian Himalayas, focusing on factors influencing their occurrence, regions of high diversity and endemism, and their overlap with protected areas. Our study highlights the need for assemblage‐level conservation strategies in high Himalaya which primarily relies on snow leopard‐focused ...

20世纪90年代以来,生态系统服务流动是目前生态学、经济学和地理学综合研究领域的热点问题。水供给服务流动特征明显,且在众多生态系统服务中占据中心位,是连接生态系统(供给区)与人类生产生活(需求区或受益区)的桥梁,是调节水流量、水循环、水质的重要途径。从供需角度分析水供给服务流动(输送区),模拟流动路径,对于实现水供给服务效益起到关键纽带作用,与此同时,它更强调社会经济与生态环境的协调配合,为建立生态系统和社会经济系统之间的联系具有重要理论和实践意义。因此,针对国内水供给服务空间流动的研究亟待开展 ...

湿地生态用水是湿地为维持自身发展过程、保证基本生态功能发挥所需要的水量,作为一种特殊的生态系统类型,湿地的生态用水计算比其他生态系统复杂,其中包括湿地植被需水量、满足蒸发需水量、湿地土壤需水量、湿地动物需水量、野生生物栖息地需水量以及景观建设需水量等等。本文介绍了用水量平衡法计算湿地生态系统需水的方法,并分别探讨了湿地中植被、土壤、生物栖息地等诸项生态需水量的计算方法。用这些方法对乌梁素海湿地的生态用水量进行了具体探索。乌梁素海湿地包括内蒙古自治区的第二大淡水湖———乌梁素海及其周围的沼泽地 ...

Extent of threats to marine fish from the online aquarium trade in the United States
The global marine aquarium hobby is a multibillion‐dollar industry, largely driven by demand from the United States. Much of this trade occurs online. We web scraped 4 major US‐based e‐commerce platforms selling marine aquarium fish to determine the retail price and source (wild capture, aquaculture, or both) of 13 families of ray‐finned marine fish ...

Survival, rarity, and extinction in tropical stony corals
Abstract Many reef‐building tropical corals are becoming rare. We considered the meaning of rarity in corals and highlighted taxa that have reached low abundances in the last few decades. The difficulties of quantifying rarity in the marine environment arise from the sheer scale and 3‐dimensional nature of the biome and the inherent challenges therein ...
