Blocking facial mimicry affects recognition of facial and body expressions
(2020)Facial mimicry is commonly defined as the tendency to imitate—at a sub-threshold level—facial expressions of other individuals. Numerous studies support a role of facial mimicry in recognizing others’ emotions. However, ...

Body-size variation across environmental gradients in an ectothermic organism: an intraspecific approach to ecogeographic patterns
(2018)Bergmann's rule states that endothermic species from cool areas tend to have larger body sizes than those from warm areas. Allen's rule maintains that endothermic species from cool environments should have shorter extremities ...
