No evidence of reactive avoidance of baboons (Papio ursinus and Papio anubis) to the presence of predators

An analysis of extensive camera trap data across four African savanna sites reveals that neither chacma nor olive baboons exhibit reactive avoidance by temporarily vacating areas following predator encounters, suggesting they rely on alternative strategies like proactive avoidance or aggressive retaliation to manage predation risk.

Modelling the interplay between inadvertent social information use and a pesticide induced foraging bias in bumblebees' crop visitation

This study uses individual-based modeling to demonstrate that while inadvertent social information use and pesticide-induced foraging biases independently alter bumblebee crop visitation patterns without affecting overall colony growth, these behavioral shifts likely modify pesticide exposure risks and should be integrated into risk assessment frameworks.

Fine-scale movements and habitat use of fish in intermittent rivers: Behavioural insights from drying refuge pools

By combining high-resolution mapping with behavioral observations, this study reveals that fish in intermittent river refuge pools exhibit size-dependent microhabitat preferences and movement patterns that persist through drying and leave lasting behavioral imprints even after rewetting, highlighting the critical conservation value of these structurally complex habitats.

Screening antifungal activity of macroalgae from SE Spain highlights the invader Rugulopteryx okamurae

This study demonstrates that macroalgae from southeastern Spain, particularly the invasive species *Rugulopteryx okamurae*, possess significant antioxidant and antifungal activities against *Fusarium oxysporum* TR4, supporting the potential valorization of invasive algal biomass as a source of bioactive compounds.

Population size estimation when multiple samples carrying the risk of misidentification are taken within the same capture occasion from the same individual

This paper introduces a new Poisson-extended latent multinomial model that accurately estimates population size in capture-recapture studies by simultaneously accounting for misidentification risks and repeated sampling of individuals within the same occasion, a scenario where existing models fail.

Can tropical agamid lizards physiologically tolerate the altered thermal mosaic of urban microhabitats?

By integrating fine-scale microclimate data with species-specific thermal traits, this study reveals that while the tropical agamid *Calotes versicolor* tolerates urban thermal mosaics well, *Psammophilus dorsalis* is more susceptible to thermal constraints in human-modified landscapes, highlighting the critical need to account for microclimatic heterogeneity and species-specific traits when predicting responses to environmental change.
