Data from: Biodiversity response to natural gradients of multiple stressors on continental margins

Erik A. Sperling, Christina A. Frieder & Lisa A. Levin
Sharp increases in atmospheric CO2 are resulting in ocean warming, acidification and deoxygenation that threaten marine organisms on continental margins and their ecological functions and resulting ecosystem services. The relative influence of these stressors on biodiversity remains unclear though, as well as the threshold levels for change and when secondary stressors become important. One strategy to interpret adaptation potential and predict future faunal change is to examine ecological shifts along natural gradients in the modern...

Data from: Eighty-five million years of Pacific Ocean gyre ecosystem structure: long-term stability marked by punctuated change

Elizabeth Sibert, Richard Norris, Jose M. Cuevas, Lana G. Graves & Jose Cuevas
While the history of taxonomic diversification in open ocean lineages of ray-finned fish and elasmobranchs is increasingly known, the evolution of their roles within the open ocean ecosystem remains poorly understood. To assess the relative importance of these groups through time, we measured the accumulation rate of microfossil fish teeth and elasmobranch dermal denticles (ichthyoliths) in deep-sea sediment cores from the North and South Pacific gyres over the past 85 million years (Myr). We find...

Data from: New deep-sea species of Xenoturbella and the position of Xenacoelomorpha

Greg W. Rouse, Nerida G. Wilson, Jose I. Carvajal & Robert C. Vrijenhoek
The discovery of four new Xenoturbella species from deep waters of the eastern Pacific Ocean is reported here. The genus and two nominal species were described from the west coast of Sweden1, 2, but their taxonomic placement remains unstable3, 4. Limited evidence placed Xenoturbella with molluscs5, 6, but the tissues can be contaminated with prey7, 8. They were then considered deuterostomes9, 10, 11, 12, 13. Further taxon sampling and analysis have grouped Xenoturbella with acoelomorphs...

Data from: Coastal landforms and accumulation of mangrove peat increase carbon sequestration and storage

Paula Ezcurra, Exequiel Ezcurra, Pedro P. Garcillán, Matthew T. Costa & Octavio Aburto-Oropeza
Given their relatively small area, mangroves and their organic sediments are of disproportionate importance to global carbon sequestration and carbon storage. Peat deposition and preservation allows some mangroves to accrete vertically and keep pace with sea-level rise by growing on their own root remains. In this study we show that mangroves in desert inlets in the coasts of the Baja California have been accumulating root peat for nearly 2,000 y and harbor a belowground carbon...
