Evolutionary Ecology & Life History Evolution of Fishes

Life History Evolution in Fishes: Synopsis

Life history variation is ubiquitous. Individual differences in fitness-related characters, such as age and size at maturity, number of eggs per female, and offspring size are the rule rather than the exception. Questions that arise in the study of life history variation include: Why do some individuals reproduce early in life, while others do so relatively late in life? Why do some individuals produce many, small offspring, while other produce few, large offspring? Why do some individuals reproduce several times throughout their life, while others die after reproducing just once? Central to my work is the premise that an understanding of life history variability is necessary to address many questions in evolutionary ecology, conservation biology, and population biology.
