Individual recognition in a jumping spider (Phidippus regius)

This study shows jumping spiders can recognize individual identities through long-term memory, challenging the assumption that only vertebrates with larger brains have this ability.

Olfactory detection and discrimination in domestic dogs (Canis lupus familiaris)

This study assesses olfactory detection and discrimination in untrained dogs across breeds using a 2AFC paradigm, finding reliable detection but limited breed-modulated discrimination abilities.

Early vocal production and functional flexibility in wild infant chimpanzees

This study identifies functional flexibility in infant chimpanzee vocalizations using AI, finding grunts are contextually variable while whimpers are not, suggesting vocal flexibility evolved before human and chimpanzee divergence.

An information-theory approach to geometry for animal groups

The paper develops an information-theory approach to analyze group behavior using GPS data from Siberian huskies, finding that 96% of location prediction is based on group member positions.

Machine learning reveals adaptive maternal responses to infant distress calls in wild chimpanzees

The paper uses machine learning to analyze distress calls from wild infant chimpanzees, showing that call variants inform maternal responses to specific events.
