A Case Report on Rehabilitation of the Asiatic Black Bear (Ursus thibetanus ussuricus) in the Wild 亚洲黑熊 (Ursus thibetanus ussuricus) 野外放归野化案例报告

open access: yesWildlife 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.

Study on the learning adaptability of College Freshmen from the perspective of ecosystem ——take B University in Guangdong as an example [PDF]

open access: yes, 2016
大学是人生发展的重要阶段,是大学生世界观、人生观、价值观形成的关键时期,是大学新生适应人生的新阶段。在大学新的学习环境,适应能力较强的大学新生能够很快适应大学学习生活。相反,适应能力较差的大学新生,则可能会遇到诸如学习动力不足、不适应大学的教与学、难以合理安排学习时间等学习上的问题,难以适应新的学习环境。因此,最紧要的是提升大学新生的学习能力,帮助大学新生迅速完成角色转变,尽快适应大学新的学习环境。 本研究拟以广东B大学为个案,选取该校大学新生作为研究对象,采用文献研究、问卷调查、访谈等方法 ...

Individual Variation in Overwintering Strategies of the Great Evening Bat (Ia io) in Subtropical China 中国亚热带地区大足蝠 (Ia io) 越冬策略的个体差异

open access: yesWildlife Letters, EarlyView.
Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

光网络中基于瓶颈链路优先的升级策略

open access: yesGuangtongxin yanjiu, 2016
针对固定栅格WDM(波分复用)光网络频谱利用率低的缺点,需对网络使用灵活栅格技术进行升级,提出了基于瓶颈链路优先的升级策略。文章定义了瓶颈链路,提出两种基于瓶颈链路的升级策略:链路密度策略和拥塞链路策略,并对这两种策略进行仿真,仿真结果显示两种策略都能够降低带宽阻塞率。链路密度策略的带宽阻塞率降低程度取决于所取阈值的不同,而拥塞链路策略能有效地降低带宽阻塞率。

the Research of American Campus Safety and Enlightment [PDF]

open access: yes, 2016
对于大多数人来讲,相比于社会更多不确定性和复杂性因素的存在,校园如同围墙里的城堡,好似同天堂一样,和谐又平静,所以许多人把校园比喻成远离危险和威胁的相对比较安全的“象牙塔”。 但是,随着社会的不断发展,越来越多不确定性因素出现了,校园变得愈加开放,使得曾经让人信任和觉得安全的校园变得愈加复杂,曾经的“象牙塔”变得让人觉得不安和恐惧。近年来,美国高校发生的校园安全事故已经不容忽视,某些安全事件的性质变得更加严重,不止是校外,整个安全事故的范围已经波及到校内,对于学生的生理和心理产生了或多或少的影响 ...

Plant economics traits predict plant carbon allocation and responsiveness to arbuscular mycorrhizal fungi under varying precipitation

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Most terrestrial plant species form symbioses with arbuscular mycorrhizal fungi (AMF). However, the below‐ground carbon (C) allocation of plants and the nutritional and growth benefits provided by AMF within this symbiosis vary greatly across species and environments ...

Prioritizing bat roosts for conservation with a global multicriteria bat roost priority index based on community science

open access: yesConservation Biology, EarlyView.
Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.
