3 CONTENTS ECOSPHERE VOLUME 8 NUMBER 1 JANUARY 2017 COVER PHOTO: Photograph of unisexual Ambystoma salamander that contains nuclear genomes from three species: A. laterale, A. texanum, and A. tigrinum. Greenwald et al. (Ecosphere, Volume 7, Issue 11, Article e01579; doi: / ecs2.1579) assessed niche partitioning of sexual and unisexual salamanders, with the prediction that unisexual forms should be more successful and abundant in marginal habitat. This prediction was upheld for one sexual-unisexual pair, but not for another. However, significant niche differentiation suggests that niche partitioning plays an important role in the evolutionary persistence of this sexual-unisexual complex. Photo Credit: Robert Denton.
