I know a fish that lives near vegetation beds, and forages for small prey. Females return to specific beaches, and there are a limited number of suitable beaches. Describe wandering and directed migration in seabirds, and give an example of each. High latitudes, coastal areas, upwelling areas. Provide examples from both marine invertebrates and marine fishes of high and low investment strategies.
Biodiversity depends on the rate of speciation.
Thus, different populations can evolve independently, and reach incompatibility especially if populations occur in different habitats. Populations will be most isolated when dispersal is short.
