Abstract
Humans have severely impacted global ecosystems and this shows few signs of abating. Many aspects of an animal's biology, including its sensory systems, may be adversely influenced by pollutants and environmental noise. This review focuses on whether and/or how various environmental disturbances disrupt the sensory systems of fishes. As critical as it is to document and understand the current effects of the human footprint, it is also important to consider how organisms might adapt to these impacts over the long term. The present paper outlines the sources of genetic and genomic variation upon which natural selection can act and then reviews examples of known genetic contributions of variation in fish chemosensory, visual and acoustico-lateralis systems.
