Individuals occupying dominant and subordinate positions in social hierarchies exhibit
divergent behaviours, physiology and neural functioning. Dominant animals express higher …

Most biomedical research is performed using a very limited number of “model” species. In
part, this has resulted from a combination of full genomes, manipulation of genes, and short …

When an individual ascends in dominance status within their social community, they often
undergo a suite of behavioural, physiological and neuromolecular changes. While these …

The field of animal personalities claims to fill a gap in our understanding of animal behavior,
because it explicitly studies the adaptive significance of behavioral differences. This is a …

Position in a dominance hierarchy profoundly impacts group members' survival, health, and
reproductive success. Thus, understanding the mechanisms that regulate or are associated …

Aggressive behavior is thought to have evolved as a strategy for gaining access to
resources such as territory, food, and potential mates. Across species, secondary sexual …

Animal welfare is a key issue not only for aquaculture industry and food production, but also
for daily husbandry practices in research topics related to physiology in wild and farmed …

Abstract Background The East African riverine cichlid species Astatotilapia burtoni serves as
an important laboratory model for sexually dimorphic physiology and behavior, and also …

In species that form dominance hierarchies, there are often opportunities for low-ranking
individuals to challenge high-ranking ones, resulting in a rise or fall in social rank. How does …
