Movement and behavioral states of common carp (Cyprinus carpio) in response to a behavioral deterrent in a navigational lock.

Background: Freshwater ecosystems are some of the most affected by biological invasions due, in part, to the introduction of invasive carp worldwide. Where carp have become established, management programs often seek to limit further range expansion into new areas by reducing their movement through interconnected rivers and waterways. Lock and dams are important locations for non-physical deterrents, such as carbon dioxide (CO), to reduce unwanted fish passage without disrupting human use.

Anthropogenic noise and the bioacoustics of terrestrial invertebrates.

Anthropogenic noise is an important issue of environmental concern owing to its wide-ranging effects on the physiology, behavior and ecology of animals. To date, research has focused on the impacts of far-field airborne noise (i.e.
