Fish, and other vertebrates, possess both a neural control system and a hormonal one dependent on the circulation. Fish hormones may be secreted by well-defined endocrine glands or by diffuse tissue and can have profound effects on the function of target tissues or organs which possess receptor molecules recognized by specific hormones. Some endocrine activities in fish are not relevant to mammals, and vice versa. Thus fish can have chromatophores controlled hormonally to change skin colour, the same hormones having different roles in mammals. Likewise, ‘prolactin’ in fish cannot regulate lactation. Individual endocrine glands, tissues and cells of fish are described in detail and the possible roles of their hormones are discussed. Fish endocrinology is becoming increasingly important with the realization of its potential applications in aquaculture and with the recognition of the consequences of pollutant endocrine disruption.Less

Human-induced environmental change currently represents the single greatest threat to global biodiversity. Species are typically adapted to the local environmental conditions in which they have evolved. Changes in environmental conditions initially influence behaviour, which in turn affects species interactions, population dynamics, evolutionary processes and, ultimately, biodiversity. How animals respond to changed conditions, and how this influences population viability, is an area of growing research interest. Yet, despite the vital links between environmental change, behaviour, and population dynamics, surprisingly little has been done to bridge these areas of research. This is the first book of its kind devoted to understanding behavioural responses to environmental change. The volume is comprehensive in scope, discussing impacts on both the mechanisms underlying behavioural processes, as well as the longer-term ecological and evolutionary consequences. Drawing on international experts from across the globe, the book covers topics as diverse as endocrine disruption, learning, reproduction, migration, species interactions, and evolutionary rescue.Less
