Peer Pressure: Do the Fitness Benefits of Animal Behavioral Traits Vary With Conspecific Density?

Ethology, EarlyView.
We show that the activity of juvenile North American red squirrels influenced their survival in a density‐dependent manner: more active individuals had higher survival under high conspecific density, whereas less active juveniles had higher survival under low densities. Juveniles who were both more active and aggressive were more likely to survive. Our

Shelters or ecological traps? Context‐dependent effects of nestboxes on breeding success in a colonial raptor

Ibis, EarlyView.
Artificial breeding structures, such as nestboxes, can potentially influence the population size and conservation status of bird species relying on heavily human‐modified environments such as agroecosystems and urban areas. However, the effectiveness of these interventions may vary, as artificial structures could attract individuals to suboptimal ...

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

Ibis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

A description of dental microanatomy and implantation geometry in Chamaeleonidae

Journal of Anatomy, EarlyView.
A reassessment of the dental histology in adult chamaeleons reveals the presence of periodontal ligament. Alongside alveolar bone and cementum, these tissues together constitute a compacted and remodelled tripartite periodontium. Our findings include the novel observation of plicidentine‐like protuberances of dentine within underlying bone.
