Wood-warbler (Parulidae) range overlap under climate change scenarios

Description:

Anthropogenic climate change will dramatically alter species distributions. The rate and magnitude of range shifts, however, will differ among taxa, resulting in altered patterns of co-occurrence and interspecific interactions. We examined potential climate-mediated breeding range shifts among North American wood-warblers (Parulidae), a speciose avian family likely to be especially impacted by such changes. We used publicly available species distribution model (SDM) range outputs to compare current ranges and patterns of sympatry among warbler species to future ranges and sympatry under 1.5 °C, 2.0 °C, and 3.0 °C of average global warming. We used these outputs to calculate average breeding range area, range overlap among species, number of sympatric species, and distances of breeding range shifts. We additionally calculated the number gained and lost sympatric interactions under each warming scenario.
