Phenotypic and Genetic Divergence among Poison Frog Populations in a Mimetic Radiation
Twomey, Evan; Yeager, Justin; Brown, Jason L.; Morales, Victor; Cummings, Molly; Summers, Kyle (2013)The evolution of Müllerian mimicry is, paradoxically, associated with high levels of diversity in color and pattern. In a mimetic radiation, different populations of a species evolve to resemble different models, which can ... -

Phylogenomic Reconstruction of the Neotropical Poison Frogs (Dendrobatidae) and Their Conservation
Guillory, Wilson X.; Muell, Morgan R.; Summers, Kyle; Brown, Jason L. (2019-01-29)The evolutionary history of the Dendrobatidae, the charismatic Neotropical poison frog family, remains in flux, even after a half-century of intensive research. Understanding the evolutionary relationships between dendrobatid ... -
Tactical reproductive parasitism via larval cannibalism in Peruvian poison frogs
Brown, Jason L.; Morales, Victor; Summers, Kyle (East Carolina University, 2009-04-23)We report an unusual example of reproductive parasitism in amphibians. Dendrobates variabi- lis, an Amazonian poison frog, oviposits at the surface of the water in small pools in plants and deposits tadpoles within the ... -
Testing for selection on color and pattern in a mimetic radiation
Yeager, Justin; Brown, Jason L.; Morales, Victor; Cummings, Molly; Summers, Kyle (2012-08-01)In this paper, we analyze variation in spectral reflectance and color pattern among populations to demonstrate dramatic divergence between four distinct morphs of the mimic poison frog Ranitomeya imitator. We also analyze ...
