Contrasting selection pressure on body and weapon size in a polygynous megaherbivore.

Biology letters - 1 Oct 2021

Shannon Graeme, Sadler Phoebe, Smith Joanna, Roylance-Casson Eleanor, Cordes Line S

Abstract excerpt

Sexual size dimorphism (SSD) is a common morphological trait in ungulates, with polygyny considered the leading driver of larger male body mass and weapon size. However, not all polygynous species exhibit SSD, while molecular evidence has revealed a more complex relationship between paternity and mating system than originally predicted. SSD is, therefore, likely to be shaped by a range of social, ecological and...
