Document Summary
Unique physical environment: fluid, 3-dimensional, vast spatial scales. Unique characteristics of marine fauna: very high fecundity, large population sizes. Fish- huge numbers of offspring per season- must overcome large juvenile mortality rate: dispersing individuals young & underdeveloped. Young end up where the currents take them: high adult vagility, large range sizes. Diversity of marine fauna: what is biodiversity:- genetic diversity. Biological diversity: the variety of life on earth. Variety of species, genes & systems: hierarchy of biodiversity, genetic diversity, species diversity, community/ecosystem diversity, scales of biodiversity, alpha, beta, gamma adaptive potential. Diversity within a species: the variety of genes within a species contributes to: the extend to which an animal can survive its environment depends on variety of genes within a population, variation within populations.
