Title: The Influence of Phylogeny, Size and Behaviour on Patterns of Covariation in Salmonid Life Histories

Principal components analysis defined a primary tactic ranking salmonids from large, early-maturing, semelparous individuals bearing few, large, rapidly developing eggs to the opposite suite of characters in small, iteroparous individuals. The analysis also defined a secondary dine from anadromous to freshwater forms, and a tertiary tactic describing variation in development. Clustering of species on the basis of life history traits reflected taxonomic affiliations. Life history traits appear to co-evolve and form successful life history strategies best suited to the biology and environment of a given taxon. Migratory behaviour and life histories are closely linked. The correspondence between behaviour and life histories may lead to unanticipated but nevertheles successful life history strategies.Read More
