Increased Circulating Levels of Testosterone and Corticosterone in Southern Toads, Bufo terrestris, Exposed to Coal Combustion Waste
This study describes an interrenal stress response in adult toads, Bufo terrestris, after exposure to coal combustion waste (characterized by a variety of trace elements). In the first portion of this study, free-ranging male toads captured at the coal ash polluted site exhibited significantly higher circulating levels of corticosterone (B) in both June/July and August […]
Noise negatively affects foraging and antipredator behaviour in shore crabs
Acoustic noise has the potential to cause stress, to distract and to mask important sounds, and thus to affect behaviour. Human activities have added considerable noise to both terrestrial and aquatic habitats, and there is growing evidence that anthropogenic noise affects communication and movement patterns in a variety of species. However, there has been relatively […]
Acoustic noise reduces foraging success in two sympatric fish species via different mechanisms
Effective foraging behaviour is essential for animals to survive and reproduce, and depends on many intrinsic and environmental factors. There is increasing evidence that man-made (anthropogenic) factors can affect the behaviour of a wide range of taxa. However, few experimental studies have investigated how foraging behaviour is affected by exposure to increased noise levels, an […]
