Across species, animals organize into social dominance hierarchies that serve to decrease
aggression and facilitate survival of the group. Neuroscientists have adopted several model …

Growing research effort has shown that physical enrichment (PE) can improve fish welfare
and research validity. However, the inclusion of PE does not always result in positive effects …

Brain evolution has often been correlated with the cognitive demands of social life. Further
progress depends on our ability to link cognitive processes to corresponding brain part sizes …

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 …

Social hierarchies are ubiquitous in social species and profoundly influence physiology and
behavior. Androgens like testosterone have been strongly linked to social status, yet the …

and rapidly respond to social and environmental information by changing their behavior. A …

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