The responsiveness of the avian stress system declines with age. A recently published study of European starlings (Sturnus vulgaris) found that a marker of biological age predicted stress responsiveness even in individuals of the same chronological age. Specifically,...

Hatching timing is under strong selection and environmentally cued in many species. Embryos use multiple sensory modalities to inform hatching timing and many have spontaneous hatching patterns adaptively synchronized to natural cycles. Embryos can also adaptively...

Spurs are a testosterone-dependent secondary sexual characteristic of male chickens (Gallus gallus domesticus) and are used as ‘weapons’ in intra-sexual fighting. While predominantly a male feature, they are also found in a small number of females. Here we show...

The recent discovery of the Araguaian river dolphin (Inia araguaiaensis) highlights how little we know about the diversity and biology of river dolphins. In this study, we described the acoustic repertoire of this newly discovered species in concert with their...

Living in social hierarchies requires individuals to adapt their behavior and physiology. We have previously shown that male mice living in groups of 12 form linear and stable hierarchies with alpha males producing the highest daily level of major urinary proteins...

The prevalence of artificial light at night (ALAN) is increasing rapidly around the world. The potential physiological costs of this night lighting are often evident in life history shifts. We investigated the effects of chronic night-time exposure to ecologically...

Carnivores are important components of ecosystems with wide-ranging effects on ecological communities. These effects are complex and vary with carnivore size, natural history, and hunting tactics, and researchers and managers must understand the ecological roles...

The Beal’s-eyed turtle (Sacalia bealei) is endemic to southeastern China and endangered due to poaching and habitat loss. Knowledge of S. bealei ecology is lacking and this study provides baseline information of its reproduction in a natural environment. We studied...

The breeding routines and foraging behaviour of many pelagic seabird species is influenced by environmental factors. Seasonality greatly affects the temporal prey availability for many marine species while the spatial distribution of prey often correlates to oceanographic...

We examined the effectiveness of simulated underground utility cable markers in hiding infrared cameras along a roadway. Our study took place in the summer of 2014 and winter of 2015 as part of a survey to determine whether swift fox (Vulpes velox) were present...

The sensory systems of Boidae and Crotalinae snakes detect subtle differences of thermal infrared energy. The complexity of this ability involves neurophysiological mechanisms with interspecific differences in the anatomy of thermoreceptor organs and functionally...

Predator pressure is a fundamental force driving changes at all levels of the community structure. It may protect native ecosystems from alien species. Therefore, resistance to diverse predators resulting from a universal anti-predator strategy seems crucial for...

Predators can play an important role in regulating prey abundance and diversity, determining food web structure and function, and contributing to important ecosystem services, including the regulation of agricultural pests and disease vectors. Thus, the ability...

Migratory species often roam vast distances bringing them into contact with diverse conditions and threats that could play significant roles in their population dynamics. This is especially true if long-range travels occur within crucial stages of a species’ annual...
