Menopause has not evolved as a general trait in mammals: A response to "Do mammals have menopause?"

The paper critiques a previous study claiming menopause is widespread in mammals, showing its methodology is flawed and concluding menopause is rare.

Group size modulates kinship dynamics and selection on social traits

This study shows that group size affects kinship dynamics and age-related social behaviors in social mammals, with smaller groups promoting more extreme helping/harming behaviors, especially in younger individuals.

Bayesian inference of toothed whale lifespans

This study develops a Bayesian mortality model to estimate lifespans and age-specific mortality in toothed whales using age-structured data from mass-strandings and other sources.

The Evolution of Democratic Peace in Animal Societies

This study applies evolutionary game theory to test the democratic peace hypothesis across animal societies, finding support for the idea that collective decision-making reduces intergroup conflict.

Partial sex linkage and linkage disequilibrium on the guppy sex chromosome

The paper analyzes PoolSeq data from guppy populations to assess sex linkage and recombination suppression, finding evidence of linkage disequilibrium but no consistent male-specific variants.

Brain monoaminergic activity during predator inspection in the Trinidadian guppy (Poecilia reticulata)

The paper examines how brain monoamine neurotransmitter activity in Trinidadian guppies changes based on social partner cooperativeness during predator inspection.

Social partner cooperativeness influences brain oxytocin transcription in Trinidadian guppies (Poecilia reticulata)

The paper examines how social partner cooperativeness affects oxytocin gene transcription in Trinidadian guppies, finding that high-predation guppies show differential oxt expression based on partner behavior.

Sensory-based quantification of male colour patterns in Trinidadian guppies reveals nonparallel phenotypic evolution across an ecological transition in multivariate trait space

The paper quantifies male color patterns in Trinidadian guppies to assess phenotypic evolution across ecological transitions, finding nonparallel divergence in multivariate trait space.

Calculating effect sizes in animal social network analysis

The paper demonstrates that relying solely on permutations to control for confounding variables in social network analysis can lead to biased and uninterpretable effect sizes, and recommends controlling for confounders in statistical models.

Common datastream permutations of animal social network data are not appropriate for hypothesis testing using regression models

The paper shows that common datastream permutations are not suitable for testing regression models in animal social networks due to high false-positive rates.
