Energetic constraints on body-size niches in a resource-limited marine environment

Sara River Bryant & Craig McClain
Body size of life on Earth spans many orders of magnitude, and with it scales the energetic requirements of organisms. Thus, changes in environmental energy should impact community body-size distributions in predictable ways by reshaping ecological and niche dynamics. We examine how carbon, oxygen, and temperature, three energetic drivers, impact community size-based assembly in deep-sea bivalves. We demonstrate that body-size distributions are influenced by multiple energetic constraints. Relaxation in these constraints leads to an expansion...

Data from: Biogeography of curimatid fishes reveals multiple lowland-upland river transitions and differential diversification in the Neotropics (Teleostei, Curimatidae)

Bruno F. Melo, James S. Albert, Fernando C. P. Dagosta & Victor A. Tagliacollo
The Neotropics harbors a megadiverse ichthyofauna comprising over 6300 species with approximately 80% in just three taxonomic orders within the clade Characiphysi. This highly diverse group has evolved in tropical South America over tens to hundreds of millions of years influenced mostly by re‐arrangements of river drainages in lowland and upland systems. In this study, we investigate patterns of spatial diversification in Neotropical freshwater fishes in the family Curimatidae, a species‐rich clade of the order...

Knifefish turning performance during forward swimming

Olivia Hawkins, Victor Ortega-Jimenez & Christopher Sanford
Rapid turning and swimming contribute to ecologically important behaviors in fishes such as predator avoidance, prey capture, mating, and the navigation of complex environments. For riverine species, such as knifefishes, that are commonly challenged by turbulent flows, turning control may be effective for counteracting adverse locomotive perturbations. Most research on fish maneuvering focuses on fish with traditional fin and body morphologies, which primarily use body bending and the pectoral fins during turning. However, it is...

Evolution in response to climate in the native and introduced ranges of a globally distributed plant

Simon Innes, James Santangelo, Nicholas Kooyers, Kenneth Olsen & Marc Johnson
The extent to which species can adapt to spatiotemporal climatic variation in their native and introduced ranges remains unresolved. To address this, we examined how clines in cyanogenesis (HCN production—an antiherbivore defense associated with decreased tolerance to freezing) have shifted in response to climatic variation in space and time over a 60-year period in both the native and introduced ranges of Trifolium repens. HCN production is a polymorphic trait controlled by variation at two Mendelian...

Data from: Price equations for understanding the response of ecosystem function to community change

Mark Genung
Biodiversity-ecosystem function research in natural ecosystems would benefit from new theoretical and analytical tools that match common characteristics of observational community data. To this end, we developed a novel, abundance-based version of the ecological Price equation in both discrete and continuous forms. As part of the presentation of this new method, we conducted two demonstration analyses. The first analysis focuses on pollination of watermelon by wild bees. We net-collected wild pollinator specimens from standard areas...

Rare and declining bee species are key to consistent pollination of wildflowers and crops across large spatial scales

Mark Genung, Mark Genung, James Reilly, Neal Williams, Andrew Buderi, Joel Gardner & Rachael Winfree
Biodiversity promotes ecosystem function in experiments, but it remains uncertain how biodiversity loss affects function in larger-scale natural ecosystems, where rare and declining species which are likely to be lost and function needs to be maintained across space and time. Here we explore the importance of rare and declining bee species to the pollination of three wildflowers and three crops using large-scale (72 sites across 5,000 km2), multi-year datasets. Half (82/164) bee species were rare...
