This review considers the evolutionary processes and physiological mechanisms that maintain or end pregnancy in mammals to formulate general, testable theoretical models that provide insights into the biology of parturition.
High-resolution GPS data revealed a quadratic relationship between group size and movement, with vulturine guineafowl groups of intermediate size exhibiting the largest home-range size and greater variation in site use.
A systematic experimental comparison of prosocial behavior in eight corvid species reveals sex-specific effects of cooperative breeding and colonial nesting, thereby adding important new insights regarding the evolution of prosociality.
Arbitration is formalised as the relative precision of predictions afforded by reward and social learning systems and is represented in modality-specific dopaminergic and dopaminoceptive regions, including the midbrain and amygdala.
Early life adversity led to hyper-innervation from the basolateral amygdala to the prefrontal cortex earlier in females than males and disrupted maturation of functional connectivity, which predicted anxiety-like outcomes.
