Specialization in plant-hummingbird networks is associated with species richness, contemporary precipitation and Quaternary climate-change velocity [PDF]

open access: yes, 2011
Large-scale geographical patterns of biotic specialization and the underlying drivers are poorly understood, but it is widely believed that climate plays an important role in determining specialization.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Species Distribution Models and Abundance Estimates Enhance Breeding Bird Atlas Data

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Our primary goal was to leverage the large amount of systematic and volunteer‐based data produced by the Minnesota Breeding Bird Atlas to develop species distribution models and population estimates for as many breeding bird species as possible. We utilized three complementary techniques to develop species distribution models and maps for 136 breeding ...

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Linking genome size variation to phenotypic selection on target traits

open access: yesEcology, Volume 107, Issue 6, June 2026.
Abstract Genome size (GS) is known to be highly variable among angiosperm species. However, this variation can also occur within species. Both interspecific and intraspecific variations in GS have been often found to be linked to phenotypic traits. Therefore, selective pressures acting on these target traits may indirectly shape GS evolution within and
