Echoes of self: Understanding acoustic structure and informational content in common marmoset (Callithrix jacchus) phee sequences

The paper analyzes the acoustic structure and informational content of common marmoset phee sequences, finding that elements encode caller identity and sex with varying accuracy across positions.

Same data, different results? Machine learning approaches in bioacoustics

The paper evaluates machine learning methods for caller identity classification in mammalian vocalizations, finding Mel-frequency cepstral coefficients and random forests provide consistent results across datasets.

Short-term memory, attentional control and brain size in primates

This study examines the relationship between brain size and short-term memory in primates, finding that overall brain size better predicts performance than specific brain regions or encephalization quotient.

Marmosets mutually compensate for differences in rhythms when coordinating vigilance

This study shows marmosets adjust their vigilance rhythms to synchronize, demonstrating flexible and controllable coupling between pairs.

Dynamic vocal learning in adult marmoset monkeys

This study tracks vocal changes in adult marmoset monkeys during social vocal accommodation and develops a model showing dynamic vocal learning mechanisms.

Human amygdala volumetric patterns convergently evolved in cooperatively breeding and domesticated species

The paper compares amygdala volume evolution in domesticated and cooperatively breeding mammals, finding convergent increases in the lateral nucleus linked to reduced fear aggression, with humans showing additional prosocial traits.

Optimising source identification from marmoset vocalisations with hierarchical machine learning classifiers

The paper develops a hierarchical machine learning classifier to accurately identify marmoset vocal sources, achieving high precision across different call types.

The evolutionary origins of primate scleral coloration

This paper tests three hypotheses about primate scleral coloration evolution by linking scleral pigmentation to social behaviors across 15 and 108 primate species.

No evidence for general intelligence in a fish

The paper tests for general intelligence (g) in cleaner fish and finds no evidence of g in ecologically non-relevant tasks, suggesting g may require a minimal brain size.
