Seasonality of temperature dependence of methane fluxes from natural wetlands
Functional Ecology, Volume 39, Issue 9, Page 2383-2397, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Temperature dependence is a crucial parameter in estimating methane (CH4) fluxes from natural wetlands, yet our understanding of this parameter remains inadequate. Seasonal fluctuations in water levels and ecosystem productivity lead to seasonal differences in CH4 ...

浙江九龙山国家级自然保护区黑麂日活动节律和垂直迁移的季节变化
野生动物学报, 2023 为准确全面地了解黑麂（Muntiacus crinifrons）在九龙山国家级自然保护区的日活动节律和某些栖息地生态因子选择的季节性规律，于2017年10月—2021年2月，在九龙山国家级自然保护区采用红外相机法对黑麂日活动节律和垂直迁移的季节变化进行研究。研究期间，共拍摄到352张黑麂照片，提取到243次有效探测。结果显示：黑麂是晨昏双峰型的昼行性动物。通过四季对比发现，黑麂夏季的活动强度比春季、秋季和冬季高，而各季节间的日活动高峰期时间段和数量存在差异。黑麂 偏好栖息于坡度为20°~40 ...

Wildlife Letters, Volume 2, Issue 3, Page 149-164, September 2024.Time‐local convex hull indicates smaller home range size for the African savannah elephants than MCP, indicating that elephants are likely exploiting certain regions more intensively rather than traveling extensively. During the transitional season, the home range size grows.

, 2008 锯缘青蟹(Scylla serrata)是生活在河口海区的一种经济甲壳动物,环境温度对其生化组成具有重要影响,而其环境温度是随季节变化而不断变化.本研究采用生物化学方法对锯缘青蟹鳃、肝胰腺和肌肉等3种器官组织中可溶性蛋白和可溶性糖含量的季节变化进行研究.结果显示锯缘青蟹3种不同器官、组织中可溶性蛋白含量,均是夏季最低,冬季最高,春秋季介于2者之间.3者的变化趋势一致,春季后降低,夏季降至最低,然后秋季和冬季依次升高.3种不同器官、组织中可溶性糖含量均是春季最高,夏季最低,秋冬季介于2者之间 ...

不同季节对半散养黑冠鹤(Balearica pavonina)行为的影响
野生动物学报, 2016 2014年4～12月,对北方森林动物园从非洲引进的半散养黑冠鹤17只,采用目标取样法和扫描法相结合的方法对其行为进行观察和对比研究。研究结果表明:不同季节对黑冠鹤行为时间分配有明显的影响,觅食行为表现为差异性显著(P≤0.05),护理行为、静栖行为、警戒行为、鸣叫行为、打斗行为表现为差异性极显著(P≤0.01),其他行为表现为差异性不显著。8月不同天气对黑冠鹤行为时间分配的影响表现为:静栖行为表现为差异性显著(P≤0.05),觅食行为、护理行为、游走行为表现为差异性极显著(P≤0.01 ...

Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Reintroduced populations are typically considered to progress through establishment, growth, and regulatory phases. However, most reintroduction programs do not monitor intensively enough to test this conceptual model. We studied population indices derived from track activity of 4 threatened species (greater bilby [Macrotis lagotis], burrowing

Wildlife mortality risk posed by high and low traffic roads
Conservation Biology, Volume 38, Issue 2, April 2024.Abstract Wildlife mortality due to collisions with vehicles (roadkill) is one of the predominant negative effects exerted by roads on many wildlife species. Reducing roadkill is therefore a major component of wildlife conservation. Roadkill is affected by various factors, including road attributes and traffic volume.

Integrative Conservation, Volume 3, Issue 1, Page 12-21, March 2024.Human–wildlife conflicts are mostly associated with social and economic impacts such as limited social interaction in fear of attacks and loss of livestock and properties. Abstract Human–wildlife conflicts (HWCs) are a worldwide problem, especially around protected areas where human and wildlife needs overlap.
