Understanding reproductive rates of wild animal populations is crucially important for management and conservation. Assessing pregnancy status of free-ranging cetaceans has historically been difficult; however, recent advances in analytical...
Employing individual measures of baseline glucocorticoids as population-level conservation biomarkers: considering within-individual variation in a breeding passerine [0.03%]
利用基线皮质类固醇的个体指标作为群体层面的保护生物标记:在一种繁殖鸣鸟中考虑个体内的变异

Labile physiological variables, such as stress hormones [i.e. glucocorticoids (GCs)], allow individuals to react to perturbations in their environment and may therefore reflect the effect of disturbances or positive conservation initiatives...
Costs of locomotion in polar bears: when do the costs outweigh the benefits of chasing down terrestrial prey? [0.03%]
极地熊追逐陆生猎物的运动成本:何时成本会超过收益?

Trade-offs between locomotory costs and foraging gains are key elements in determining constraints on predator-prey interactions. One intriguing example involves polar bears pursuing snow geese on land. As climate change forces polar bears ...

Most of southern Africa's elephants inhabit environments where environmental temperatures exceed body temperature, but we do not know how elephants respond to such environments. We evaluated the relationships between apparent thermoregulato...
Salinity tolerances of two Australian freshwater turtles, Chelodina expansa and Emydura macquarii (Testudinata: Chelidae) [0.03%]

Estuarine habitats are frequently used as nurseries by elasmobranch species for their protection and abundant resources; however, global climate change is increasing the frequency and severity of environmental challenges in these estuaries ...
The use of α- or β-blockers to ameliorate the chronic stress of captivity in the house sparrow (Passer domesticus) [0.03%]
α或β受体阻滞剂在改善房室 Sparrow(Passer domesticus)的压力中的作用

When wild animals are brought into captivity for the first time, they frequently develop chronic stress symptoms. Animals can develop glucocorticoid dysregulation or changes in the sympathetic nervous system over the course of the first wee...
Feather corticosterone levels are related to age and future body condition, but not to subsequent fitness, in a declining migratory songbird [0.03%]
羽毛皮质醇水平与一种衰退的迁徙鸣鸟的年龄和未来的体质状况有关,但与随后的适应性无关
Than J Boves,Graham D Fairhurst,Clark S Rushing et al.
Than J Boves et al.
In migratory species, breeding and non-breeding locations are geographically separate, yet the effects of conditions from one stage may carry over to affect a subsequent stage. Ideally, to understand the mechanisms and implications of 'carr...
