Data from: Diversity in thermal affinity among key piscivores buffers impacts of ocean warming on predator-prey interactions
Asymmetries in responses to climate change have the potential to alter important predator-prey interactions, in part by altering the location and size of spatial refugia for prey. We evaluated the effect of ocean warming on interactions between four important piscivores and four of their prey in the U.S. Northeast Shelf by examining species overlap under historical conditions (1968-2014) and with a doubling in CO2. Because both predator and prey shift their distributions in response to changing ocean conditions, the net impact of warming or cooling on predator-prey interactions was not determined a priori from the range extent of either predator or prey alone. For Atlantic cod, an historically dominant piscivore in the region, we found that both historical and future warming led to a decline in the proportion of prey species' range it occupied and caused a potential reduction in its ability to exert top-down control on these prey. In contrast, the potential for overlap of spiny dogfish with prey species was enhanced by warming, expanding their importance as predators in this system. In sum, the decline in the ecological role for cod that began with overfishing in this ecosystem will likely be exacerbated by warming, but this loss may be counteracted by the rise in dominance of other piscivores with contrasting thermal preferences. Functional diversity in thermal affinity within the piscivore guild may therefore buffer against the impact of warming on marine ecosystems, suggesting a novel mechanism by which diversity confers resilience.

Data from: Evolution of a cross-feeding interaction following a key innovation in a long-term evolution experiment with Escherichia coli
<p>The evolution of a novel trait can profoundly change an organism's effects on its environment, which can in turn affect the further evolution of that organism and any coexisting organisms. We examine these effects and feedbacks following the evolution of a novel function in the Long-Term Evolution Experiment (LTEE) with <em>Escherichia</em> <em>coli</em>. A characteristic feature of <em>E. coli</em> is its inability to grow aerobically on citrate (Cit<sup>−</sup>). Nonetheless, a Cit<sup>+</sup> variant with this capacity evolved in one LTEE population after 31,000 generations. The Cit<sup>+</sup>clade then coexisted stably with another clade that retained the ancestral Cit<sup>−</sup> phenotype. This coexistence was shaped by the evolution of a cross-feeding relationship based on C<sub>4</sub>-dicarboxylic acids, particularly succinate, fumarate, and malate, that the Cit<sup>+</sup> variants release into the medium. Both the Cit<sup>−</sup> and Cit<sup>+</sup> cells evolved to grow on these excreted resources. The evolution of aerobic growth on citrate thus led to a transition from an ecosystem based on a single limiting resource, glucose, to one with at least five resources that were either shared or partitioned between the two coexisting clades. Our findings show that evolutionary novelties can change environmental conditions in ways that facilitate diversity by altering ecosystem structure and the evolutionary trajectories of coexisting lineages.</p>
