WebThus as proposed by the member/vagrant hypothesis (Sinclair 1988), the absolute abundance of a species may be a function of physically driven expansion and contraction of the spatial (and temporal) extent of areas where life cycle closure is possible. Life history diversity thus may affect the overall carrying capacity of an estuary for salmon.

Atlantic herring connectivity: implications for population richness

WebClupea harengus (Atlantic herring) is increasingly being regarded as a model species for population dynamics studies of marine fishes. In fact, some of the main population concepts in marine fishes like member/vagrant hypothesis or dynamic balance concept have been proposed and refined due to herring studies.
