Data from: Climatic warming and the future of bison as grazersJoseph M. Craine, E. Gene Towne, Mary Miller & Noah Fierer
Climatic warming is likely to exacerbate nutritional stress and reduce weight gain in large mammalian herbivores by reducing plant nutritional quality. Yet accurate predictions of the effects of climatic warming on herbivores are limited by a poor understanding of how herbivore diet varies along climate gradients. We utilized DNA metabarcoding to reconstruct seasonal variation in the diet of North American bison (Bison bison) in two grasslands that differ in mean annual temperature by 6 °C....
Data from: The Hawaiian freshwater algae biodiversity survey (2009-2014): systematic and biogeographic trends with an emphasis on the macroalgaeAlison R. Sherwood, Amy L. Carlile, Jessica M. Neumann, J. Patrick Kociolek, Jeffrey R. Johansen, Rex L. Lowe, Kimberly Y. Conklin & Gernot G. Presting
Background A remarkable range of environmental conditions is present in the Hawaiian Islands due to their gradients of elevation, rainfall and island age. Despite being well known as a location for the study of evolutionary processes and island biogeography, little is known about the composition of the non-marine algal flora of the archipelago, its degree of endemism, or affinities with other floras. We conducted a biodiversity survey of the non-marine macroalgae of the six largest...
Data from: Transcriptional variation associated with cactus host plant adaptation in Drosophila mettleriKim Hoang, Luciano M. Matzkin & Jeremy M. Bono
Although the importance of host plant chemistry in plant–insect interactions is widely accepted, the genetic basis of adaptation to host plants is not well understood. Here, we investigate transcriptional changes associated with a host plant shift in Drosophila mettleri. While D. mettleri is distributed mainly throughout the Sonoran Desert where it specializes on columnar cacti (Carnegiea gigantea and Pachycereus pringleii), a population on Santa Catalina Island has shifted to chemically divergent coastal prickly pear cactus...
Data from: Three types of rescue can avert extinction in a changing environmentRuth A. Hufbauer, Marianna Szűcs, Emily Kasyon, Courtney Youngberg, Michael J. Koontz, Christopher M. Richards, Ty Tuff & Brett A. Melbourne
Setting aside high-quality large areas of habitat to protect threatened populations is becoming increasingly difficult as humans fragment and degrade the environment. Biologists and managers therefore must determine the best way to shepherd small populations through the dual challenges of reductions in both the number of individuals and genetic variability. By bringing in additional individuals, threatened populations can be increased in size (demographic rescue) or provided with variation to facilitate adaptation and reduce inbreeding (genetic...
