Interspecific territoriality has facilitated recent increases in the breeding habitat overlap of North American passerines

The paper examines how interspecific territoriality affects range dynamics in North American passerines, finding increased fine-scale spatial overlap for species engaging in territorial behavior.

Multiple routes to interspecific territoriality in sister species of North American perching birds

The paper examines interspecific territoriality in sister bird species, finding it is common in sympatric pairs and linked to recent divergence, with hybridization playing a complex role in species range dynamics.

Continent-scale phenotype mapping using photographs from citizen scientists

This paper develops a method to quantify phenotypes from citizen scientists' photographs and applies it to study geographical and temporal variation in two damselfly species.

An assessment of phylogenetic tools for analyzing the interplay between interspecific interactions and phenotypic evolution

This study evaluates phylogenetic tools for analyzing how interspecific interactions and phenotypic evolution influence each other, finding that current methods often fail to detect interaction effects and that process-based models perform better.
