Strategic adjustment of parental care in tree swallows: life-history trade-offs and the role of glucocorticoids [PDF]

Royal Society Open Science, 2016
Life-history theory predicts that optimal strategies of parental investment will depend on ecological and social factors, such as current brood value and offspring need.

Light‐Driven Quadrupedal Walking Biohybrid Robot With Antagonistic Muscle‐Rings and Inclined Joints

Advanced Robotics Research, EarlyView.
This work presents a light‐driven quadrupedal walking biohybrid robot powered by antagonistic muscle‐rings that achieve alternating walking gait. Optical training improved reproducibility of cultured muscle tissues, while caffeine treatment enhanced contractile force.

Calls during agonistic interactions vary with arousal and raise audience attention in ravens

Frontiers in Zoology, 2017
Background Acoustic properties of vocalizations can vary with the internal state of the caller, and may serve as reliable indicators for a caller’s emotional state, for example to prevent conflicts.

An attention bias test to assess anxiety states in laying hens [PDF]

PeerJ, 2019
Fear is a response to a known threat, anxiety is a response to a perceived threat. Both of these affective states can be detrimental to animal welfare in modern housing environments.

Utterance evolution: the road to generative, combinatorial communicators

Biological Reviews, EarlyView.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

Dance behaviour in cockatoos: Implications for cognitive processes and welfare.

PLoS ONE
Parrots (Aves, Psittaciformes) in captivity have been reported to show dance behaviour in response to music, which may involve complex cognitive processes including imitation, vocal learning and entrainment.
