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 ...

Zhejiang Daxue xuebao. Lixue ban, 2018 青藏高原和印度洋均对我国气候有重要影响，研究高原和印度洋的热力状况及其耦合关系对全面了解我国的天气现象具有重要意义.利用1981 — 2010年(30 a)欧洲中心ERA-interim的青藏高原和印度洋温度资料，以及NCEP/NCAR的垂直速度和风速资料，分析了青藏高原地气温差和印度洋海气温差的特征及其相互影响.结果表明，高原冬、夏季地气温差有所区别：冬季地气温差呈东北-西南向的带状分布，在高原中部、西南边界喜马拉雅山脉地区和东南边界出现了较大的负值中心，其他地区均为正值；夏季地气温差均为正值 ...

, 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,

Zhejiang Daxue xuebao. Lixue ban, 2014 利用1960~2004年NCEP/NCAR全球再分析资料、SMIP2海温资料和我国160站逐月降水和气温观测资料，考虑到大气在从低纬到中高纬地区的能量传播的桥梁作用，首先对冬季印度洋海温距平场与同期北半球500 hPa位势高度距平场进行奇异值分解(SVD)，然后分析印度洋海温异常与我国冬季气温和降水的关系.研究结果表明，冬季印度洋海温距平场第1奇异向量(SVD1)是全区一致的单极型分布形势，与我国冬季气温和东南地区降水的相关性非常显著.当冬季印度洋海温距平场第1奇异向量处于正位相时，印度洋海温异常偏暖 ...

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 ...

Concurrent Crises and Non‐State Service Provision
Risk, Hazards &Crisis in Public Policy, Volume 17, Issue 3, September 2026.ABSTRACT Concurrent crises represent a significant challenge for disaster and public health governance. Activated in response to one threat, governing institutions may be distracted or stretched thin during an emergent crisis. In such crises, governments and communities rely heavily on non‐state service providers such as non‐profit organizations and ...

Wildlife Letters, Volume 4, Issue 3, Page 139-148, September 2026.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.

Wildlife Letters, Volume 4, Issue 2, Page 73-82, June 2026.Eimeria saudiensis represents a genus of apicomplexan parasites capable of inducing coccidiosis in Arabian oryx. Our research concentrated on the morphological and molecular investigation of Eimeria spp. in the captive oryx herd in Oman. The therapeutic and management practices employed at the Mammals Breeding Center were reassessed to diminish ...

, 2014 為探討巨峰葡萄之種子數與果粒大小的關係，本試驗分別於夏季及冬季調查中部各主要產地葡萄之種子數目及其發育情形。由調查之結果發現，夏季葡萄之果粒顯著地較含相同種子數之冬季葡萄為大，其與種子數之相關係數亦顯著地較冬季葡萄為大。夏季葡萄之種子數雖較冬季葡萄稍多，但是其中約有35%屬發育不全之種子，而且單為結果之果粒數亦高佔10%。冬季葡萄不僅發育不全之種子只有4%、無單為結果，而且含2個種子以上的果粒顯著地較夏季葡萄為多。各產地之夏季葡萄平均正常種子數除豐原市的1.2個較少外，其他鄉鎮均為1.4個 ...
