In this study we analyze the role of phylogeny, environment, and community structure on sociality. Using structural equation modeling (SEM) we aim to quantify the direct and indirect impacts of variables on behaviors including social grouping, reproduction, and space use among Carnivora species.

2010年6月,在上海动物园繁殖场的赤斑羚饲养区,采用人为观察与摄像监控相结合的方式对10只圈养赤斑羚的行为时间分配和活动规律进行了研究。结果表明,赤斑羚一天的大部分时间用于趴卧(43.11%)和采食(38.21%),站立行为(12.40%)次之,运动行为(3.53%)和修饰行为(2.45%)较少,其他行为仅占0.31%,所占比例最低。在活动规律上,赤斑羚一般在7:00左右开始活动,一天中趴卧、采食和站立是主要的3种行为。趴卧行为在11:00~11:55和15:00~15:55处形成波峰,在8:00~8:

We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

为恢复并提高笼养金钱豹的野性和兽性,使其不至于丧失在野外生存的能力,对广州动物园试验场的4只金钱豹进行了为期近2个月的采食过程行为观察。结果表明,笼养金钱豹的年龄越大,越常表现出一系列的刻板行为,这种行为在采食前表现更为突出。而采食活体动物能有效地减少刻板行为的发生,并提高其野性和兽性。

Abstract Pollinator conservation schemes typically focus on conserving existing, restoring degraded, or creating new wild bee habitats. Their effectiveness depends on dispersal corridors enabling habitat colonization by bees. However, the role of seminatural linear landscape structures (LLS) in connecting pollinator communities across intensively ...

2010年3~4月,对北京动物园的圈养蜂猴分阶段进行不同的食物投喂方式的丰容试验,第一阶段采取分时段投喂方式;第二、三阶段在第一阶段的基础上定时在其生活环境中分别加入装有不同活食(蟋蟀、蝗虫、面粉虫等)的PVC管,采用焦点动物法和瞬时取样技术对其中1只呼名为"宝宝"的个体行为变化进行观察记录。结果表明,分时段投喂方式和PVC管活食食物丰容均增加了蜂猴与摄食相关的行为,休息相关行为减少。食物丰容对蜂猴的行为具有刺激作用,减少了刻板行为的发生频率。

Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem
Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant

2011年1~2月,采用瞬时扫描法对徐州金桥珍禽养殖场的黑天鹅进行了研究。研究发现,黑天鹅在孵化期具有一定的行为时间分配。行为时间分配为:孵化29.96%、理羽15.06%、采食11.87%、游泳10.22%、站立8.09%、游走7.15%、筑巢7.07%、警戒6.09%、休息3.00%、对鸣1.53%。对不同性别黑天鹅的时间分配进行独立样本T检验,结果显示:除筑巢行为差异显著 ...

Qilianshan National Park covers approximately 40% of core snow leopard habitat patches and 50% of movement corridors between patches. Including more of these important areas within the park boundaries should be considered, as the Qilianshan National Park sits at a pivotal juncture between critical snow leopard habitat in China and Mongolia, and may ...
