野生动物学报, 2021 2017年冬季，为检验杭州动物园黑猩猩冬季饲料是否在行为和营养上满足需求，粗略计算黑猩猩冬季饲料营养成分，与日本、阿根廷、上海野生动物园、国内动物园的日粮营养成分对比，同时参照中国营养学会推荐的人类膳食营养平衡标准和AZA黑猩猩饲养指南，结合杭州动物园黑猩猩实际生长发育情况，评估黑猩猩冬季饲料。结果显示，杭州动物园冬季黑猩猩饲料在营养成分上，总能量（105—159 MJ），高于黑猩猩维持能量（711—8372 MJ），蛋白质（79—119 g）、脂肪（55—83 g）、碳水化合物（401—602

野生动物学报, 2011 2006年6月～2007年3月,在湖北五峰后河国家级自然保护区内,应用选择系数、选择指数、判别分析,对果子狸在秋冬季节栖息地的选择和利用进行了初步研究。研究结果表明,秋季与冬季果子狸对栖息地的选择有差异性。秋季在低海拔地区有较多林木果实、藤本果实成熟,不需要消耗太多能量即可满足自身需要。冬季气温下降,果子狸较喜欢选择海拔较高的阳坡活动,以获取更多热量。

野生动物学报, 2020 剑湖是云贵高原重要的水鸟越冬地，掌握其冬季水鸟群落特征对水鸟保护以及湿地资源管理具有重要指导意义。于2017年和2018年冬季采用样点法对剑湖进行了水鸟多样性调查。共记录到水鸟6目9科36种，种类组成上以雁形目鸭科鸟类为主（16种），但数量上以秧鸡科骨顶鸡（36.53%）和紫水鸡（17.09%）为优势。根据物种丰富度非参数估计，剑湖水鸟丰富度为42.80 ± 0.86。从居留类型上来看，剑湖水鸟以冬候鸟为主，占总记录种数的72.22%。对比两冬季数据发现剑湖水鸟多样性存在显著的年际变化 ...

Wildlife Letters, Volume 1, Issue 3, Page 119-130, September 2023., 2023 We collected Amur tiger track data and occurrence data through snow track tracking, sample line surveys, and camera traps. The study concluded that forest roads, scrub vegetation, and human landscape factors were the main factors influencing Amur tiger movements at fine scales and examined the negative correlation between tiger path curvature values ...

Survey optimization for invasive Burmese pythons informed by camera traps 基于自动相机监测技术的入侵物种缅甸蟒的调查优化
Wildlife Letters, Volume 1, Issue 3, Page 143-148, September 2023., 2023 We evaluated the utility of camera traps to survey invasive Burmese pythons in the Florida Keys by deploying cameras pointed towards target areas of known radiotagged snakes under two trigger mechanisms—motion‐triggered or timelapse. We estimated detection probability and diel activity to optimize future surveys using timelapse camera traps and paired ...

Trends and progress in studying butterfly migration 蝴蝶迁徙行为的研究趋势与进展
Integrative Conservation, Volume 1, Issue 1, Page 8-24, December 2022., 2022 We show (i) the potential importance of non‐English‐language literature for understanding butterfly migration globally, (ii) studies are mostly concentrated in North America and Europe with very few from the tropics, (iii) most studies are focused on three species: the Monarch (Danaus plexippus), Painted Lady (Vanessa cardui) and Red Admiral (Vanessa ...

Unravelling the processes between phenotypic plasticity and population dynamics in migratory birds
Journal of Animal Ecology, Volume 91, Issue 5, Page 983-995, May 2022., 2022 This work highlights the critical role of the stopover stage of northward migration in the influence of migration tactics and population dynamics of migratory birds across the whole annual cycle. The authors also demonstrate the key processes linking individual migration tactics and population dynamics.

, 2019 月季是我国重要的美化环境的树种,在北方地区冬季幼树常发生抽条问题,表现出枝条从上到下干死,严重时整株干死。月季抽条发生主要在早春枝条发芽前,这时气温逐步升高,说明抽条发生的原因不是冻害,而是生理干旱引起的。下面谈谈月季幼树冬季抽条的解决办法。1.整株埋土月季枝条丛生,同时比较软,对于幼树一般栽种第一年可以用土埋起来,防止水分蒸发,

Wildlife Letters, EarlyView.Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.
