New Lit Alert: A global meta-analysis reveals higher variation in breeding phenology in urban birds than in their non-urban neighbours

A global meta-analysis reveals higher variation in breeding phenology in urban birds than in their non-urban neighbours Pablo Capilla-Lasheras, Megan J. Thompson, Alfredo Sánchez-Tójar, Yacob Haddou, Claire J. Branston, Denis Réale, Anne Charmantier, Davide M. Dominoni Abstract Cities pose a major ecological challenge for wildlife worldwide. Phenotypic variation, which can result from underlying genetic variation... Continue Reading →

Meta-analysis of Urban Bird Phenology

Humans have significantly impacted environmental conditions and landscapes for several decades through our urban expansion. These changes have produced selective pressures different from those present in non-urban areas. In response to these selective pressures, many species have diverged in physical, behavioral, and reproductive traits between their urban and non-urban populations. In addition, urban landscapes are... Continue Reading →

A Global Analysis of Urban Reptiles

One of the outstanding questions in urban evolutionary biology is whether there are universal or predictable responses to urbanization, and if so, what factors influence urban tolerance. As small-bodied ectotherms, reptiles are particularly sensitive to many of the challenges of urban life. For example, reptiles appear to be more sensitive to habitat fragmentation than birds,...

Defining Urbanization: A New Conceptual Framework

What is urbanization and how do we, as urban evolutionary biologists, ecologists, and conservation biologists, define this metric? We've written about this topic before and a new paper by Remington Moll et al. titled "What does urbanization actually mean? A framework for urban metrics in wildlife research" takes a deep dive into defining urbanization. Generally,... Continue Reading →
