This study evaluated the effects of providing 3–15 kg of a soluble and biodegradable biopolymer-based enrichment material (blend of biodegradable polymers and natural fibers) to prepartum sows housed in farrowing crates. Fifteen sows were blocked by body weight and backfat thickness and assigned to three treatments: no enrichment material (CONT), 3 kg of enrichment material (BN3), or 15 kg of enrichment material with added nut...
Extinct Species Unearth Bergmann's Rule in CanidaeNARA Subscribed
Aim Interspecific patterns of Bergmann's rule may be concealed by species extinctions within clades. We evaluate whether incorporating extinct species and paleoenvironmental information improves the detection of Bergmann's rule in the family Canidae, and test whether temperature and net primary productivity (NPP) explain interspecific variation in canids' body mass. Location Global. Time Period Neogene to present. Taxon Canida...
Strengthening biodiversity conservation and One Health through ranger monitoring of wildlife health in protected areasNARA Subscribed
The lack of wildlife health (WH) surveillance systems leaves critical gaps in biodiversity conservation and One Health protection. Integrating rangers patrolling protected areas (PAs) into WH monitoring represents a cost‐effective and scalable opportunity to address these gaps at key human–wildlife interfaces and nature strongholds. For the past 2.5 years, organizations across 4 countries have collaborated to pilot this integr...
Photogrammetry has become an essential tool in medical and research fields for generating high-fidelity 3D models from 2D images. However, optimizing the imaging and processing parameters remains a challenge, particularly for fresh brain specimens, where repeated imaging is not feasible. This study systematically evaluates the impact of various Metashape alignment settings on 3D reconstruction outcomes, analyzing 12,600 config...
Aim Anurans' sensitivity to hydric stress has driven adaptive changes in multiple traits, potentially displaying geographical clines, as is the case with body size. A longstanding body of research suggests that skin resistance to water loss may also vary geographically in response to water loss. We build upon biophysical first principles to test for the existence of this yet elusive global‐level cline in skin resistance to deh...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
