Evolutionary Applications, Volume 13, Issue 10, Page 2791-2806, December 2020., 2020 Abstract Variation in size and age at maturity is an important component of life history that is influenced by both environmental and genetic factors. In salmonids, large size confers a direct reproductive advantage through increased fecundity and egg quality in females, while larger males gain a reproductive advantage by monopolizing access to females.

Evolutionary Applications, Volume 12, Issue 2, Page 214-229, February 2019., 2019 Abstract Males of many fish species exhibit alternative reproductive tactics, which can influence the maturation schedules, fishery productivity, and resilience to harvest of exploited populations. While alternative mating phenotypes can persist in stable equilibria through frequency‐dependent selection, shifts in tactic frequencies have been observed ...

Ecosphere, Volume 10, Issue 1, January 2019., 2019 Abstract Animal consumers track spatial variation in resource phenology (i.e., resource waves) to prolong their access to ephemeral foods. While recent work has revealed how animals move across landscapes to exploit phenological variation among discrete foraging patches, much less is known about how variation nested within patches influences the ...
