Data from: Evolutionary history and biogeographical patterns of barnacles endemic to deep-sea hydrothermal vents

Santiago Herrera & Timothy M. Shank
The characterization of evolutionary and biogeographical patterns is of fundamental importance to identify factors driving biodiversity. Due to their widespread but discontinuous distribution, deep-sea hydrothermal vent barnacles represent an excellent model for testing biogeographic hypotheses regarding the origin, dispersal, and diversity of modern vent fauna. Here we characterize the global genetic diversity of vent barnacles to infer their time of radiation, place of origin, mode of dispersal, and diversification. Our approach was to target a...

Data from: Indirect human impacts reverse centuries of carbon sequestration and salt marsh accretion

Tyler C. Coverdale, Caitlin P. Brisson, Eric W. Young, Stephanie F. Yin, Jeffrey P. Donnelly & Mark D. Bertness
Direct and indirect human impacts on coastal ecosystems have increased over the last several centuries, leading to unprecedented degradation of coastal habitats and loss of ecological services. Here we document a two century temporal disparity between salt marsh accretion and subsequent loss to indirect human impacts. Field surveys, manipulative experiments and GIS analyses reveal that crab burrowing weakens the marsh peat base and facilitates further burrowing, leading to bank calving, disruption of marsh accretion, and...

Data from: Habitat-driven population structure of bottlenose dolphins, Tursiops truncatus, in the North-East Atlantic

Despite no obvious barrier to gene flow, historical environmental processes and ecological specializations can lead to genetic differentiation in highly mobile animals. Ecotypes emerged in several large mammal species as a result of niche specializations and/or social organization. In the North-West Atlantic, two distinct bottlenose dolphin (Tursiops truncatus) ecotypes (i.e. ‘coastal’ and ‘pelagic’) have been identified. Here, we investigated the genetic population structure of North-East Atlantic (NEA) bottlenose dolphins on a large scale through the...

Data from: Leaf litter nutrient uptake in an intermittent blackwater river: influence of tree species and associated biotic and abiotic drivers

Andrew S. Mehring, Kevin A. Kuehn, Aaron Thompson, Catherine M. Pringle, Amy D. Rosemond, Matthew R. First, R Richard Lowrance & George Vellidis
1. Organic matter may sequester nutrients as it decomposes, increasing in total N and P mass via multiple uptake pathways. During leaf litter decomposition, microbial biomass and accumulated inorganic materials immobilize and retain nutrients, and therefore, both biotic and abiotic drivers may influence detrital nutrient content. We examined the relative importance of these types of nutrient immobilization and compared patterns of nutrient retention in recalcitrant and labile leaf litter. 2. Leaf packs of water oak...

Data from: Evidence of concurrent local adaptation and high phenotypic plasticity in a polar microeukaryote

Karin Rengefors, Ramiro Logares, Johanna Laybourn-Parry & Rebecca J. Gast
Here we investigated whether there is evidence of local adaptation in strains of an ancestrally marine dinoflagellate to the lacustrine environment they now inhabit (optimal genotypes) and/or if they have evolved phenotypic plasticity (a range of phenotypes). Eleven strains of Polarella glacialis were isolated and cultured from three different environments: the polar seas, a hyposaline and a hypersaline Antarctic lake. Local adaptation was tested by comparing growth rates of lacustrine and marine strains at their...
