This study tests positive and negative cognitive biases in cockroaches to assess the presence of affective states in invertebrates.

This study tests if injured cockroaches prefer analgesics and show altered behavior, finding no analgesic preference but increased abnormal behaviors.

This study investigates whether cockroaches can make motivational trade-offs, finding they avoid light-exposed food but do not adjust preferences flexibly, suggesting limited cognitive complexity.

This study finds no link between social network position and exploration tendency in cockroaches, and reports a single axis of social behavior variation.

This study examines social behavior consistency in cockroaches under varying humidity, finding that groups show higher plasticity variance than individuals.

The paper examines whether social plasticity in bottlenose dolphins relates to fitness by analyzing social behavior in response to salmon abundance and its link to reproductive success.

This study assesses the impact of RFID and marker recognition tags on cockroach movement using automated video tracking and finds no significant effect from RFID but increased movement with marker labels.

This paper quantifies the impact of indirect genetic effects (IGEs) on heritable variation and evolutionary potential across 21 species, finding IGEs significantly increase heritability and are most prominent for behaviors.

The paper examines DNA methylation changes in social spiders before and after infection, finding increased methylation in CpG, CHG, and CHH contexts but no clear immune-related patterns.
