- | Evolutionary trade-offs are crucial to understanding dimorphism in a species. A common choice revolves around the distinction natural and sexual selection: for a male, is it better to outcompete other males in the fight for resources or in their sexual prowess? | + | Evolutionary trade-offs are crucial to understanding dimorphism in a species.

- | A clear example of this dilemma appears in the bulb mite //R. robini// -- an acarus often considered a pest in plantations around the world. Males of this species can be either brawny fighters or skinny scramblers. While fighters obviously come on top in the competition for resources, Van den Beuken et al. (2018) have found that scramblers can sire a higher number of offspring, balancing the scales and ensuring the morph' | + | {{ http://www.uva.nl/binaries/twocolumnlandscape/ |
