Abstract EN
Urban areas are expanding globally, and the impact of high human population density (HHPD) on bird species richness remains unresolved.
Studies primarily focus on species richness along an urban-to-rural gradient; however, some studies have analyzed larger-scale patterns and found results that contrast with those obtained at smaller scales.
To move the discussion beyond static species richness patterns, we analyzed the effect of HHPD on bird assemblage dynamics (year-to-year extinction probability, turnover, changes in species richness) across the United States over a 25-year period.
We found that bird assemblages in both high and low human population density areas changed significantly over the period of record.
Specifically, bird assemblages increased in species richness on average.
Assemblage change in areas of HHPD was not significantly different from assemblage change in areas with LHPD.
These results suggest that human population density alone does not alter the persistence of avian assemblage patterns.
