This study examines how chacma baboons adjust their antipredator behaviors in response to changes in predator density and species, finding context-dependent flight and vigilance responses.

Emergent smartphone temporal structures reflect cognitive constraints

This study shows that cognitive constraints measured in speeded tasks influence long-term smartphone temporal patterns, revealing how cognitive processes shape naturalistic behavior.

Behavioral heterogeneity in host-seeking and post-feedingsuppression among disease vector mosquitoes

The paper compares host-seeking behavior and post-blood meal suppression across Aedes, Anopheles, and Culex mosquitoes, identifying interspecific differences in behavioral patterns.

Consolation behaviour in pigs: Prior exposure to group members in need of help drives targeted affiliation and facilitates social buffering

This study shows pigs provide consolation through targeted affiliation after observing a stressed partner, reducing anxiety, while direct reunions increase anxiety and non-affiliative interactions.

Persistent male survival advantage in a protogynous hermaphrodite fish

The paper tracks sex-specific survival and growth in a protogynous fish during climate stress, finding higher male survival despite expected female vulnerabilities.

A Method for Visual Psychophysics based on the Navigational Behaviour of Desert Ants (Melophorus bagoti)

This study demonstrates a method to assess visual psychophysics in desert ants by observing changes in their navigational behavior when visual stimuli are altered.

Assessments of Evoked and Spontaneous Pain Following Administration of Gabapentin and the Cannabinoid CB2 agonist LY2828360 in a Rat Model of Spared Nerve Injury

This study evaluates the effects of LY2828360, a CB2 agonist, on evoked and spontaneous pain in a rat spared nerve injury model, finding robust suppression of evoked pain but variable results for spontaneous pain assessed via CPP.

Sex-Dependent Effects of Chronic Stress During Adolescence on Cognitive Bias and Functional Connectome in Young Adult Rats

This study examines how chronic stress during adolescence affects cognitive bias and brain connectivity differently in male and female rats, revealing sex-specific neural reorganization linked to depression risk.

This study examines the sublethal behavioural and neurotoxic effects of wastewater effluent exposure on noble crayfish, finding altered locomotion, olfactory avoidance, and reduced cholinesterase activity.

Awake and hungry: artificial light at night disrupts behaviour and reproductive ecology in a wild migratory bird

This study shows that artificial light at night disrupts nocturnal behavior and reduces reproductive success in collared flycatchers by altering parental care and nestling development.

Effects of nicotinic receptor antagonism on nicotine and THC self-administration in a model of polysubstance use

This study examines how nicotinic receptor antagonists affect nicotine and THC self-administration in rats, showing differential effects based on drug availability and receptor subtype.

Low-dimensional latent spaces identify the functional structure of individual behavioral phenotypes

The paper uses multi-domain telemetry data to infer stable individual latent representations, revealing that low-dimensional embeddings capture key behavioral phenotypes like risk-taking and social cohesion.

Flexibility in task performance and division of labour in a cooperatively breeding cichlid

This study examines task specialization and coordination in cooperatively breeding cichlids, finding no consistent division of labour and instead task contagion where individuals follow others in task execution.
