Jan 10, 2022 · The dynamics of rank across development (e.g. being raised by humans is associated with reduced dominance in juvenile greylag geese (Anser anser) ) and life-history stages (e.g. dispersal in spotted hyenas ) add further complexity to the ways that dynamic rank links to fitness.
Jan 10, 2022 · Their results suggest that dominance ranks are at least partially based on structural dependence between relationships rather than individual attributes alone . Winner–loser effects are one key mechanism by which social interactions facilitate the formation of linear dominance hierarchies.
Feb 19, 2018 · Now, a new study shows that a previously subordinate animal can become dominant after optogenetic stimulation of the dorsomedial prefrontal cortex, demonstrating that this brain region is necessary and sufficient to quickly induce winning during social competitions.

Sep 9, 2020 · We propose that simple ordinal rank best predicts traits when competition is density-dependent, whereas proportional rank best predicts traits when competition is density-independent. We found that for 75% of traits (15/20), one rank metric performed better than the other.
