The evolution and the adaptive logic (if any) of female mate choice are subjects of lively debate. Whereas most researchers believe that females have evolved to recognize signs of male 'quality' (the ability to provide females or their offspring with direct or indirect genetic or material benefits), there is intriguing evidence that males can evolve to appeal to pre-existing female preferences....

It is now well-established that reproduction in wildlife can be disrupted by anthropogenic environmental changes, such as chemical pollution. However, very little known about how these pollutants might affect the interplay between pre- and post-copulatory mechanisms of sexual selection. Here, we investigated impacts 21-day exposure male eastern mosquitofish (Gambusia holbrooki) to a field-reali...

Ultraviolet B radiation (UV-B) is an important environmental driver that can affect locomotor performance negatively by inducing production of reactive oxygen species (ROS). Prolonged regular exercise increases antioxidant activities, which may alleviate the negative effects of UV-B-induced ROS. Animals naturally performing exercise, such as humans performing regular exercise or fish living in ...

The hypothesis is tested that toxicity of acid mine drainage can be detected by a selection of existing macroinvertebrate community and bioindicator metrices supplemented by toxicity tests with the local mosquitofish Gambusia holbrooki Girard and the shrimp Atyaephyra desmaresti Millet. The behavioural responses of A. desmaresti to acid mine drainage were recorded in the Multispecies Freshwater...
