Secondary Sympatry as a Sorting Process Open
A much remarked‐upon pattern in nature is elevated trait disparity in sympatric relative to allopatric populations or species. Early explanations focused on secondary contact between allopatrically speciating taxa and emphasised adaptive d…

The comparative analysis of lineage-pair traits Open
A powerful but poorly understood analysis in ecology and evolutionary biology is the comparative study of lineage-pair traits. “Lineage-pair traits” are characters like ‘diet niche overlap’ and ‘strength of reproductive isolation’ that are…

phylopairs: Comparative Analyses of Lineage-Pair Traits Open
Facilitates the testing of causal relationships among lineage-pair traits in a phylogenetically informed context. Lineage-pair traits are characters that are defined for pairs of lineages instead of individual taxa. Examples include the st…

Character displacement drives trait divergence in a continental fauna Open
Significance A foundational concept in evolutionary ecology is that resource competition and other costly interactions drive trait divergence between closely related species—a process known as “character displacement.” Consistent with this…
