Data are from a factorial experiment designed to test the effects of small mammals and above- and below-ground invertebrates on plant species richness and composition in native tallgrass prairie (Gibson et al. 1990, https://doi.org/10.1007/BF00318268).
Data from: Na+/K+‐ATPase gene duplications in clitellate annelids are associated with freshwater colonizationKevin M. Horn, Bronwyn W. Williams, Christer Erséus, Kenneth M. Halanych, Scott R. Santos, Michel Des Châtelliers Creuzé & Frank E. Anderson
Major habitat transitions, such as those from marine to freshwater habitats or from aquatic to terrestrial habitats, have occurred infrequently in animal evolution and may represent a barrier to diversification. Identifying genomic events associated with these transitions can help us better understand mechanisms that allow animals to cross these barriers and diversify in new habitats. Study of the Capitella telata and Helobdella robusta genomes allows examination of one such habitat transition (marine to freshwater) in...
Data from: Worth the reward? An experimental assessment of risk-taking behavior along a life history gradientAdam C. Behney, Ryan O'Shaughnessy, Mike W. Eichholz & Joshua D. Stafford
Life history theory predicts that species with faster life history strategies should be willing to risk their survival more to acquire resources than those with slower life history strategies. Foraging can be a risky behavior and animals generally face a tradeoff between food consumption and predation risk. We predicted that the degree to which animals invest in current vs. future reproduction (i.e., life history strategy) would determine how they approach this tradeoff. We manipulated food...
1. The amount and patterns of phylodiversity in a community are often used to draw inferences about the local and historical factors affecting community assembly and can be used to prioritize communities and locations for conservation. Because measures of phylodiversity are based on the topology and branch lengths of phylogenetic trees, which are affected by the number and diversity of taxa in the tree, these analyses may be sensitive to changes in taxon sampling and...
Links between prey assemblages and poison frog toxins: a landscape ecology approach to assess how biotic interactions affect species phenotypesIvan Prates, Andrea Paz, Jason Brown & Ana Carnaval
Ecological studies of species pairs showed that biotic interactions promote phenotypic change and eco-evolutionary feedbacks. However, it is unclear how phenotypes respond to synergistic interactions with multiple taxa. We investigate whether interactions with multiple prey species explain spatially structured variation in the skin toxins of the Neotropical poison frog Oophaga pumilio. Specifically, we assess how dissimilarity (i.e., beta diversity) of alkaloid-bearing arthropod prey assemblages (68 ant species) and evolutionary divergence between frog populations (from a...
1. Random species loss has been shown experimentally to reduce ecosystem function, sometimes more than other anthropogenic environmental changes. Yet, controversy surrounds the importance of this finding for natural systems where species loss is non-random. 2. We compiled data from 16 multi-year experiments located at a single site in native tallgrass prairie. These experiments included responses to 11 anthropogenic environmental changes, as well as non-random biodiversity loss - either the removal of uncommon/rare plant species...
