New Lit Alert: Growing up in a new world: trait divergence between rural, urban, and invasive populations of an amphibian urban invader

Growing up in a new world: trait divergence between rural, urban, and invasive populations of an amphibian urban invader Max Mühlenhaupt, James Baxter-Gilbert, Buyisile G. Makhubo, Julia L. Riley, John Measey Abstract Cities are focal points of introduction for invasive species. Urban evolution might facilitate the success of invasive species in recipient urban habitats. Here...

Little Urban Dragons

James Baxter-Gilbert and colleagues from down under — Julia Riley and Martin Whiting — have been digging into the ecological and evolutionary responses to urbanization in a charismatic and common (at least if you're in Australia) group of lizards: Australian water dragons (Intellagama lesueurii). Previously, we told you about their findings that urban dragons are innately bold. In... Continue Reading →

Anoles Adapt to Beat the Urban Heat

Urban areas are hot. The urban heat island effect causes urbanized regions to be significantly warmer than nearby forested areas, and the tropical islands of the Caribbean are no exception to this pattern. Just spend a few minutes in the noon heat in San Juan, Puerto Rico, and you will beg for the cool reprieve... Continue Reading →

Toxic Toads in a Toxic World

Common toad Bufo bufo

The Common European Toad, Bufo bufo, is a pond-breeding amphibian found throughout Europe, including in urban environments.  Ecological changes (e.g., predator communities) in anthropogenic habitats present novel challenges to the common toad, but abiotic changes (e.g., pollution) may also influence phenotypes in these landscapes. Nevertheless, we know relatively little about how these urban-dwellers (and specifically their toxins)... Continue Reading →

Evolution 2019: A Test for Transgenerational Plasticity in the Adaptive Divergence of Acorn Ant Thermal Tolerance Across an Urban-Rural Temperature Cline

Populations are often challenged to live in novel or rapidly changing environments. This is probably most clear in cities where new habitat is being created causing native species to encounter novel habitat features. But because of this, cities set the stage to help researchers understand the plastic and evolutionary shifts that occur in wild organisms.... Continue Reading →
