Description and Impact of Encounters With Deceased Partners or Spouses.

This study investigates perceived interactions with the deceased, a phenomenon reported across societies, with 30-34% of individuals likely experiencing at least one ADC in their lifetime. Despite this prevalence, studies examining the impact of ADCs' on those who have lost partners are limited. We present data from 70 individuals reporting partner ADCs via an online survey.

Genotype-by-genotype epistasis for exploratory behaviour in .

Social interactions can influence the expression and underlying genetic basis of many traits. Yet, empirical investigations of indirect genetic effects (IGEs) and genotype-by-genotype epistasis-quantitative genetics parameters representing the role of genetic variation in a focal individual and its interacting partners in producing the observed trait values-are still scarce. While it is commonly observed that an individual's traits are influenced by the traits of interacting conspecifics, representing social plasticity, studying this social plasticity and its quantitative-genetic basis is notoriously challenging.

Does Divergence in Habitat Breadth Associate with Species Differences in Decision Making in and ?

Decision making is involved in many behaviors contributing to fitness, such as habitat choice, mate selection, and foraging. Because of this, high decision-making accuracy (i.e.
