Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

The costs of extra‐pair behaviours in birds
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations
ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.

We used 4 sampling methods to estimate or index the abundance and sex ratio of spotted salamanders (Ambystoma maculatum) over 14 years. The present study highlights the importance of considering individual heterogeneity in capture probability when estimating abundance of pond‐breeding amphibians from capture data with imperfect detection. Abstract Long‐

DNA barcoding for identification of species involved in wildlife strikes at Brazilian airports
A collaborative network of 42 Brazilian airports applied DNA barcoding to identify 80 species involved in wildlife strikes. Among them, 32 species (17 birds and 15 bats) were not currently available in Brazil's wildlife strike reporting database, underscoring the value of molecular tools for strengthening wildlife strike monitoring.

Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.

High philopatry rates of Yellow-legged Gulls in the southeastern part of the Bay of Biscay
Background Philopatry rate is one of the main factors shaping population dynamics in colonial seabirds. Low rates of philopatry are linked to populations with high dispersal, while high rates are linked to populations with a very high spatial structure ...

Behavioral responses of black bears to human presence and infrastructure in Yosemite National Park
Using GPS collar data from black bears in Yosemite National Park, we examined how bear spatiotemporal activity in relation to human development shifted during the COVID‐19 park closure in 2020. In the absence of visitors, bears maintained consistent landscape‐scale space use but altered fine‐scale spatial and temporal behaviors.
