Fitness trade-offs and the maintenance of alternative male morphs in the bulb mite (Rhizoglyphus robini).

Abstract excerpt

Alternative reproductive phenotypes (ARPs) occur across a wide range of taxa. Most ARPs are conditionally expressed in response to a cue, for example body size, that reliably correlates with the status of the environment: individuals below the (body size) threshold then develop into one morph, and individuals above the threshold develop into the alternative morph. The environmental threshold model provides a...
