Frederick (Eric) I. Archer, PhD

Geneticist, Protected Resources Division,Southwest Fisheries Science Center

Dr. Archer's graduate work focused on describing and comparing morphometric and genetic variation in striped dolphins. From that he developed an interest in the detection of population subdivision in small cetaceans and the creation of analytical tools for genetic data that will assist managers in the identification of marine mammal stocks. He has also been involved in research on the effects of the ETP tuna purse-seine fishery on dolphin reproduction and early mortality.

Scholarly and Creative Work

Archer's research is directed toward improving our understanding of the population dynamics of pelagic delphinids and how they are affected by long-term, anthropogenic factors, such as tuna purse-seine fishing. He studies intra- and interspecific diversity in small cetaceans with respect to patterns of population divergence. To do this, he has developed and integrated morphometric and genetic analytical techniques for examinations of variation at multiple taxonomic levels.

Some of Archer's recent projects include:

Examinations of fishery data for evidence of mother-calf separation and age/sex selectivity during purse-seine operations

Modeling age/length curves and weaning for various dolphin stocks

A comparative study of the evasive behavior of various ETP dolphins

Construction of a fishery effort index model using dolphin tracking and tagging data

Modeling bowhead whale population structureIncorporating genetic phase uncertainty in analyses of SNP data

Investigating the behavior and appropriate use of Fst and analogs for describing population subdivision and dispersal

Population structure and taxonomy of fin whales
