Anthropogenic disturbances have been implicated in the rapid decline of amphibians. Disturbances, such as disease and poor water quality, might cause changes in the physiology of amphibians resulting in chronic stress, which can result in decreased g

Spawning behaviors of the Devils River minnow (Dionda diaboli) were observed in the Devils River, Val Verde County, Texas. Spawning in the wild was observed over active and inactive nests of centrarchids near openings of a spring. Nests consisted of

Social interactions of conspecifics are a function of complex relationships involving resource defense, antipredatory tactics, and mate acquisition. Consequently, individuals often associate non-randomly with conspecifics in their habitats, with spat

Visible marks can aid in population studies but, depending on the type of mark used, may result in poor retention and increased mortality. Visible implant elastomer (VIE) was evaluated as a marking technique for two species listed as endangered or th
