Behavioral interventions to reduce demand for threatened freshwater turtles as pets

open access: yesConservation 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 ...

Extreme site fidelity in long‐distance migratory shorebirds in Australia and potential implications for conservation

open access: yesConservation 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 ...

干旱半干旱区退化草地土壤水分变化及其对降雨时间格局的响应

open access: yesShuitu 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 ...

黄土丘陵区柠条人工林土壤水分动态

open access: yesShuitu 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 ...

Genomics‐informed management of ex situ populations

open access: yesConservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

A Locally Retentive HfO2–STING Nano‐Radiosensitizer Hydrogel for Enhanced Radioimmunotherapy in Esophageal Cancer

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Esophageal squamous cell carcinoma (ESCC) remains associated with frequent local recurrence and distant metastasis despite advances in radiochemotherapy and immunotherapy, highlighting the need for therapeutic strategies that improve both local tumor control and systemic antitumor immune responses.

咸水淋洗改良滨海盐渍土的潜力研究

open access: yesShuitu 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 ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Ecohydrological characteristics of biocrusts explain divergent responses of biocrusts and grasses to rainfall reduction

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2843-2860, September 2026.
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.
