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 →

Big in the City: Urban Eco-Evolutionary Dynamics in Bumblebee Body Size and Pollination

Urbanization is arguably one of the most rapid and conspicuous human-driven environmental changes, and fragmentation is one of the most pervasive outcomes of urbanization. Patches of vegetation within the built matrix of a typical cityscape, such as parks and gardens, are usually small and isolated and movement among them potentially jeopardized. Bumblebees are common in... Continue Reading →
