How identity bias affects perceptions of conservation messages on social media

Conservation Biology, EarlyView.
Abstract Public support is essential for conservation, as public opinion can influence decision‐making and policy. Therefore, understanding whether bias toward conservationists due to their identity (identity bias) affects their perceived credibility and support for their recommendations is important.

Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

Ecological Entomology, EarlyView.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

A sensory ecology approach to understanding snakebites: Influence of sensory cues on the strike of the lancehead pitviper

Journal of Zoology, EarlyView.
Snakes are notable for having a broad range of predators and one of the most diverse repertoires of defensive behaviors. During heightened responses to aversive stimuli, one of the behaviors displayed is the venomous bite, particularly relevant because it triggers snakebite incidents in humans.

Which, when, and where traits matter: functional trait‐mediated species associations shift with microenvironmental and climatic variation

New Phytologist, EarlyView.
Community‐level fitted relationship between spatial association Lij and trait dissimilarity (tDij) at the fine spatial scale (r = 40 mm; where r represents the radius around individuals of the focal species). Summary Predicting coexistence in species‐rich plant communities requires understanding the role of functional traits in species interactions and
