A graduate opportunity (M.Sc. or Ph.D.) is available to study adaptive differences in juvenile growth and metabolism among different ecotypes of rainbow trout (large lake piscivores vs. insectivores).
Selection for differences in growth is a fundamental driver of adaptive differentiation among species and populations. However, the physiological drivers and consequences of high growth remain poorly understood, as are the ecological tradeoffs that select for differences in growth.
Piscivorous and insectivorous populations of rainbow trout differ in maximum body size and growth, providing a good model for understanding the associations between growth, physiology, and ecological drivers.
Research will focus on physiological differences and potential tradeoffs among traits related to growth, metabolism, and aerobic performance (e.g. growth efficiency, digestive anatomy, standard and maximum metabolism, aerobic performance, behaviour), and whether the integrated phenotype of juveniles matches productivity of their natal rearing habitats.
Lab and field work will be based out of the University of British Columbia, Vancouver, starting in Sept. 2016 or Jan 2017.
Students with an interest and background in physiology, ecology, and growth of salmonids are preferred.
