Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Drylands are mainly structured by both vascular plants and biological soil crusts (biocrusts), the latter often regarded as a self‐organizing component of these ecosystems.

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.

Advancing conservation breeding programs for marine invertebrates
Conservation Biology, EarlyView.Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Shuitu Baochi Xuebao, 2020 降雨是干旱半干旱地区的主要水分来源，降雨量、降雨时长和降雨强度等共同影响降雨入渗，进而影响降雨对地表下不同土层的补充。研究干旱半干旱区退化草地生态系统不同土层土壤水分对不同量级降雨时间格局的动态响应变化，对于揭示水土关键要素、草地荒漠化防止及应对气候变化的影响均具有重要意义，基于2018年连续对锡林郭勒盟正镶白旗额里图牧场的降雨及地表下5，15，30，60，100 cm的土壤体积含水率数据的观测，探讨了各土层土壤水分变化及其对降雨事件大小的响应。结果表明：对于干旱半干旱区草地而言，降雨可以显著影响5 ...

Shuitu Baochi Xuebao, 2023 明确黄土丘陵区降雨对土壤水分影响,对准确评估降雨格局变化对生态系统结构和功能的影响具有重要意义。以陕北黄土丘陵区退耕地栽植后自然撂荒23年的柠条人工纯林为研究对象,通过土壤湿度传感器监测不同土层土壤体积含水量,探讨不同土层土壤水分补充增量对降雨特征(降雨量、降雨历时和降雨强度)的响应。结果表明:(1)土壤水分消耗和补充主要集中于0-500 cm土层,其月变化在垂直剖面呈"双峰"(4—5月)、"单峰"(6月)和"双峰"(7—10月),随土层深度增加变化率减弱;(2)当降雨量>4 ...

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, EarlyView.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, EarlyView.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 ...

Shuitu Baochi Xuebao, 2011 通过室内土柱模拟试验,研究了不同矿化度咸水对砂壤质滨海盐碱土土壤入渗特征的影响,以及咸水淋洗土壤水盐变化规律和节水潜力。研究结果表明,高矿化度咸水略微降低土壤入渗性能,但当淋洗水矿化度高于15.61g/L时,土壤入渗性能不再继续降低;不同矿化度水处理淋出液矿化度都经历快速下降、较快下降、缓慢下降3个阶段,土壤盐分随咸水淋洗水量的增加先上升,再经历急剧下降、快速下降、缓慢下降,土壤经咸水淋洗后盐分含量明显下降;根据水盐平衡预估咸水淋洗具有较高的节水潜力,5.35g/L和10.36g ...

Conservation Biology, EarlyView.Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...
