Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

open access: yesIntegrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Volatile Compounds in Feathers of the Scarlet Macaw (Ara macao) Reflect Sex and Pair‐Bond Status

open access: yesIntegrative Zoology, EarlyView.
Scarlet macaws exhibit sex‐ and pair‐related differences in plumage volatile composition, with males showing greater chemical richness. Partnered individuals differ in specific compound classes, whereas no clear association with immune function was detected. These results support a potential role for olfactory cues in sexual and social communication in

Dorsal Crypsis and Chemical Defense Jointly Shape Brain Size in Toads

open access: yesIntegrative Zoology, EarlyView.
We found that total brain size and dorsal crypsis under both ultraviolet‐sensitive (UVS) and violet‐sensitive (VS) tetrachromatic bird visual models were negatively associated across eight species of toads. Our findings suggest that when species reduce predation risk by evolving increased dorsal crypsis, they may exhibit decreased brain size due to ...

Smoke signals: Measuring wildlife smoke exposure with animal‐borne and stationary sensors

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Wildfires are becoming larger, more frequent and more severe, producing smoke plumes that degrade air quality hundreds of kilometres away and for days to weeks after an active fire. Despite public health and safety concerns regarding wildfire smoke, we know little about how free‐ranging wildlife experience or respond to these exposures.

Unraveling Suicidal Ideation and Behaviors in a Global Cohort of Individuals at Clinical High‐Risk for Psychosis: Multivariable Correlates and Subthreshold Psychotic Symptoms

open access: yesActa Psychiatrica Scandinavica, EarlyView.
ABSTRACT Introduction Suicidal ideation and behaviors (SIB) are common among individuals at clinical high risk for psychosis (CHR‐P), but their relationship with the overall clinical profile remains unclear. This study aimed to identify sociodemographic/clinical factors associated with SIB in CHR‐P individuals and to examine whether subthreshold ...
