This book is an essential read for students of evolutionary processes. Chum salmon, Oncorhynchus keta, are used as an excellent example of the development of intra-specific genetic divergence by temporal isolation. Seasonally distinct reproductive populations are common in many taxa including flowering plants, insects and fishes. By examining the relative contributions of genotype and enironment to phenotypic diversity among seasonally isolated chum stocks the work provides insight into the process of sympatric speciation. Data from field and laboratory work is integrated to clearly show that…mehr

Produktbeschreibung
This book is an essential read for students of evolutionary processes. Chum salmon, Oncorhynchus keta, are used as an excellent example of the development of intra-specific genetic divergence by temporal isolation. Seasonally distinct reproductive populations are common in many taxa including flowering plants, insects and fishes. By examining the relative contributions of genotype and enironment to phenotypic diversity among seasonally isolated chum stocks the work provides insight into the process of sympatric speciation. Data from field and laboratory work is integrated to clearly show that both disruptive and stabilizing selective forces contribute to phenetic and genetic diersity. This work represents one of the earliest examples of the process of ecological speciation in fishes.

Autorenporträt
Dr. Tallman has been a practicing scientist in fisheries and ecology for over 30 years. He has undertaken research on each of Canadäs three oceanic coasts. His work comprises studies of Pacific salmon, Atlantic groundfish and over the last 2 decades Arctic species such as Arctic charr, lake trout and various whitefishes.
