Special Session - Benthic vertebrates: Ecology and conservation of substrate-oriented fishes | |||
Fishes with specialized benthic habits – those that spawn, feed, and/or shelter extensively on the bottom - are a diverse and unique component of aquatic ecosystems. Benthic fishes influence ecosystem processes; they can modify habitats by rearranging substrate during spawning and foraging, and affect community structure through predation effects. Benthic orientation in fishes has also been identified as a correlate of imperilment among freshwater fishes, due to factors such as restricted movement and their dependence on the ecological integrity of the benthic environment. This session will focus on benthic specialization, its ecological roles, and implications for conservation of fishes. | |||
