Obesity Alters the Vascular Morphology and VEGF‐A Signaling in Adipose Tissue
Obesity alters cell geometry and vessel morphology in mice adipose tissue by increasing adipocyte size by 78% and reducing vessel density by 51%, while vessel size and capillary basement membrane thickness remain unchanged. Obesity also affects angiogenesis, which is mediated by vascular endothelial growth factor (VEGF) binding kinetics.

This study highlights that assessments of forests' climate resilience require multiple aspects of phenology (mean intensity, amplitude and timing) rather than a single performance indicator. The decline of leaf and fruit production, as well as the temporal mismatches in leaf turnover and reproduction, will have cascading impacts on trophic interactions

Optimism and pessimism: a concept for behavioural ecology
ABSTRACT Originating from human psychology, the concepts of “optimism” and “pessimism” were transferred to animal welfare science about 20 years ago to study emotional states in non‐human animals. Over time, “optimism” and “pessimism” have developed into valuable welfare indicators, but little focus has been put on the ecological implications of this ...

Planting native wildflowers improves vacant land as bee habitat in a post‐industrial city
Greening with native wildflowers in urban vacant land (pocket prairies) increases bee abundance and species richness in the post‐industrial city of Cleveland, Ohio, USA. Pocket prairies supported a similar bee abundance to Metropark grasslands in the surrounding landscape, but Metropark grasslands supported significantly higher bee diversity and ...

An adult male Barbary macaque displays a novel gesture in the species' repertoire, that is, hand‐clapping, which he uses for agonistic signalling. The individual directs the hand‐clap at conspecifics, combines the gesture with other agonistic behaviours and/or facial expressions, and elicits either a submissive or counter‐aggressive response from the ...
