Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors

open access: yesJournal of Animal Ecology, EarlyView.
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...

The Evolution of Male Weapons Is Associated with the Type of Breeding Site in a Clade of Neotropical Frogs

open access: yesIntegrative Zoology, EarlyView.
Male weaponry evolution is often linked to male–male competition, but its relationship with breeding site type remains unclear. Using Leptodactylinae frogs, we found a macroevolutionary correlation between breeding site type and weapon evolution. Also, gains and losses of weapons occurred more frequently in exposed‐breeding sites, an unexpected finding.

Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders

open access: yesIntegrative Zoology, EarlyView.
Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Urbanization and Vector Species Shape Avian Malaria Prevalence in Mosquitoes

open access: yesIntegrative Zoology, EarlyView.
Avian malaria prevalence was assessed in two mosquito species across urban and peri‐urban habitats. No infections were detected in either species in urban areas, while a 2.53% prevalence was found in the native Culex pipiens from peri‐urban sites, highlighting the influence of urbanization on parasite transmission dynamics.

Morphotype Bias, Morph Specific Recruitment and No Elevation‐Life History Relation in High Altitude Mesquite Lizard Populations

open access: yesIntegrative Zoology, EarlyView.
Site‐level differences in population growth (λ) and phenotype frequencies. Mountain silhouettes represent the three study sites. Morph relative abundances are shown in the colored vertical bar. Point estimates and confidence intervals of λ for each site are displayed below, with the dashed line marking the threshold for demographic stability (λ = 1 ...
