Fitness and Selection in Natural Systems

I aim to connect the ecological dynamics I explore in movement and disease ecology with the evolutionary implications by quantifying fitness and selection. Investigating evolutionary forces gives us a deeper understanding of the systems we study and is important for understanding variation we encounter in natural systems.

Individual habitat specialization and fitness

I will explore how individual caribou vary in habitat type specialization through time and between individuals in the Fogo Island caribou population. I will then investigate the relationship between specialization and fitness by showing which individuals calve each year and how long their calves survive.

(non)parallel evolution in trinidadian guppies

Conducted a systematic review of literature within the Trinidadian guppy system over 40 years. We sought to determine how strong parallel evolution is in the classic high and low predation dichotomy seen in guppy literature and then to determine ecological factors that impact this.
