Colorful traits in avian females, individual condition, reproductive performance, and male mate preferences: A meta-analytic approach

América Hernández, Margarita Martínez-Gomez, René Beamonte-Barrientos & Bibiana Montoya
Colorful ornaments in females are suggested to have evolved and be maintained by sexual selection. Although several studies have evaluated this idea evidence is still equivocal. Results from empirical studies have been compilated in reviews, but quantitative analyses have seldom been performed. Here, using a meta-analytic approach, we show that evidence from empirical studies conducted in birds, supports the ideas that colorful female ornaments are positively associated with individual condition, reproductive performance, and male-mate preferences....

Interactions between species are influenced by different ecological mechanisms, such as morphological matching, phenological overlap, and species abundances. How these mechanisms explain interaction frequencies across environmental gradients remains poorly understood. Consequently, we also know little about the mechanisms that drive the geographical patterns in network structure, such as complementary specialization and modularity. Here, we use data on morphologies, phenologies and abundances to explain interaction frequencies between hummingbirds and plants at a large geographic scale. For...

Bat acoustic libraries are important tools that assemble echolocation calls to allow the comparison and discrimination to confirm species identifications. The Sonozotz project represents the first nation-wide library of bat echolocation calls for a megadiverse country. It was assembled following a standardized recording protocol that aimed to cover different recording habitats, recording techniques, and call variation inherent to individuals. The Sonozotz project included 69 species of echolocating bats, a high species richness that represents 50%...

Community-level reorganizations following migratory pollinator dynamics along a latitudinal gradient

Ainhoa Magrach, Carlos Lara, Márquez-Luna Ubaldo, Sergio Díaz-Infante & Ingrid M. Parker
Predicting how communities re-arrange in response to changes in species composition remains a key challenge in ecology. Migratory species, which enter and leave communities across latitudinal gradients, offer us a unique opportunity to evaluate community and species-level responses to a shift in community composition. We focused on a migratory hummingbird and the communities that host it along a latitudinal and species diversity gradient. Our results show higher niche overlap in more diverse communities, allowing resident...
