CSEE2020: Variation in Pollinator-mediated Plant Reproduction Across an Urbanization Gradient

Recently, Ruth Rivkin shared some of her dissertation work with the Canadian Society for Ecology and Evolution (CSEE). Urban habitats are more fragmented and degraded than nonurban habitats, which can impact both the ecology and evolution of species interactions. Species interaction may be particularly sensitive to urbanization because the species involved may be responding to... Continue Reading →

CSEE2020: Human Influences on Darwin’s Finches

The Galápagos Islands are renowned for their unique, endemic biodiversity which inspired Charles Darwin to develop his theory of evolution by natural selection. In particular, Darwin’s finches are an iconic example of adaptive radiation due to natural selection, where ~18 species have evolved from a single, common ancestor. Adaptive radiations can occur when exploitation of... Continue Reading →

Urban Galápagos: Part 1

Galápagos Islands

What does it mean to be urbanized on a volcanic archipelago? With ‘Darwin Day’ (February 12th) just behind us, my upcoming research trip to the Galápagos Islands feels almost unbelievably well-timed. My goal will be to study one of the fabled Darwin’s finches, the small ground finch (Geospiza fuliginosa), and its relationship with an invasive... Continue Reading →
