- Machine vision methods for analyzing social interactions
Summary: We review recent developments in machine vision for automatic, quantitative analysis of social behavior that have changed the scale and resolution with which we can dissect interactions between animals.
- Cognitive skills and the evolution of social systems
Summary: Animals interacting successfully use cognitive skills such as recognizing individuals, their social rank and logic as described here in a cichlid fish, and the neural bases of these skills are identified.
- Modification of feeding circuits in the evolution of social behavior
Summary: Social behaviors are linked to foraging behavior on a behavioral and mechanistic level, and we propose that modifications of feeding circuits are crucial in the evolution of social behaviors.
- Evidence for an audience effect in mice: male social partners alter the male vocal response to female cues
Highlighted Article: Mice modify their vocalizations in response to audiences, but not to simple social stimuli, constituting a novel paradigm for measuring the influence of social cues.
- Differences in electrosensory anatomy and social behavior in an area of sympatry between two species of mormyrid electric fishes
Summary: Differences in the sensory system that mediates electric communication correlate with differences in social behavior between two sympatric species of African mormyrid fishes.
- The mechanosensory lateral line is used to assess opponents and mediate aggressive behaviors during territorial interactions in an African cichlid fish
Highlighted Article: Hydrodynamic cues are needed for assessment and non-contact fight behaviors during territorial interactions in an African cichlid fish.
- Sound pressure enhances the hearing sensitivity of Chaetodon butterflyfishes on noisy coral reefs
Summary: Butterflyfish detect sound pressure to enhance hearing and aid social communication in a noisy environment.
