Data and code from: Revisiting the evolution of wing dimorphisms in the genomics era

Dispersal strategies are critical life history traits influencing
bio-geographical, ecological, and evolutionary patterns and processes
including range-expansion and contractions, abiotic and biotic
interactions, and rates of speciation. Yet, dispersal strategies are
challenging to study because they are complex suites of morphological,
physiological, and behavioral traits. Thus, our understanding of how and
why dispersal strategies evolve remains incomplete. Wing dimorphisms have
evolved repeatedly within nearly every major insect order and are
characterized by the co-occurrence of fully winged dispersing and short-
or wingless non-dispersing morphs within species or populations, making
them ideal model systems for studying the evolution of alternative
dispersal strategies. Forty years ago, Derek Roff proposed that wing
dimorphisms are a threshold trait which evolves as an intermediate step on
the trajectory toward complete loss of flight, driven by the high
physiological and life history costs of dispersal. Here, we provide the
data files and R-script used for a phylogenetic reconstruction of wing
dimorphism in the well-developed model Gryllus field crickets.
