Abstract Reversing ongoing biodiversity loss requires effectively managing anthropogenic threats. Although conservation actions can mitigate these threats, prioritizing and targeting such actions remain challenging because species respond differently depending on the nature of the threats and their biological traits.

Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

不同季节对半散养黑冠鹤(Balearica pavonina)行为的影响
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 ...

Abstract Adaptive management of threatened species relies on having ex ante estimates of species’ responses to different interventions. Structured expert elicitation is often used to generate these estimates, but comparisons of these expert‐predicted outcomes with observed results are rare.

2014~2015年4~6月,采用瞬时扫描法和计时法对长春市动植物园内已配对多年的成年白头鹤(Grus monacha)进行交尾及孵化期行为观察。观察结果表明:笼养白头鹤交尾期行为时间分配比例以护理(24%)、游走(25%)、站立(16%)、采食(15%)为主要行为; 孵化期以繁殖行为(50%)为主; 其他各行为比例均低于10%。交尾和孵化期雌雄性各行为时间分配比例均无明显差异(P>0.05)。随着孵化期由前到后及环境温度的逐渐升高,笼养白头鹤平均晾卵时间在前期为(3.21 ±0.57)min ...

How endorser attributes influence conservation communication
Abstract Conservation communication often uses the celebrity endorsement strategy. However, robust evidence regarding its effectiveness is still limited. More importantly, practitioners do not have guidelines for selecting an ideal endorser because there is no clear consensus on what endorser attributes are most critical.

为了探讨峨眉山藏猕猴与游客接触相互行为与猴和游客年龄/性别组间的关系,以及猴群对游客的攻击行为,2010年4月13~18日和9月24日~10月5日共16 d以峨眉山一线天生态猴区藏猕猴与游客为研究对象进行观察。结果表明:青年猴与未成年、20~30岁、30~50岁和50岁以上各年龄阶段的女性游客接触行为比例最高,均占一半以上,分别为62.5%、57.82%、56.12%、52%,且藏猕猴与不同性别、年龄的游客接触相互行为变化差异极显著 ...

ABSTRACT Oral interaction plays a facilitative role in second language acquisition. While numerous studies have explored adult learners’ interactions, research that has examined young learners’ interactions, especially among Chinese as a second language learners (CSLs), is lacking. This study focused on CSLs and Chinese‐speaking students (CSSs) in Hong

发酵床对圈养山魈(Mandrillus sphinx)行为的影响
2013年12月1日~2014年2月1日,以上海动物园繁殖场内的11只山魈(Mandrillus sphinx)为研究对象,分为2组做发酵床丰容对照实验,实验组山魈4只,对照组山魈7只,分析了发酵床垫料对圈养山魈活动行为比例的影响。发酵床的垫料分别由木屑、米糠、黄土组成,投放比例为5:4:1。结果表明,在有丰容设施时,山魈的休息行为和刻板行为明显减少,摄食和玩耍行为明显增加,与预期结果一致。在对丰容设施的利用上,增加的丰容垫料设施有效地促进了山魈对垫料的利用。实验组山魈的垫料活动行为包括探究、咀嚼 ...
