FALCON: a software package for analysis of nestedness in bipartite networks

Publication ID: pub.1028484012

Publication date: 06/08/2014

Keywords: Comparison; Contexts; FALCON Software Package; Measures and Null Models; Methods; Nestedness; Networks; Statistical Significances

Nestedness is a statistical measure used to interpret bipartite interaction data in several ecological and evolutionary contexts, e.g. biogeography (species-site relationships) and species interactions (plant-pollinator and host-parasite networks). Multiple methods have been used to evaluate nestedness, which differ in how the metrics for nestedness are determined. Furthermore, several different null models have been used to calculate statistical significance of nestedness […]

Ocean acidification increases copper toxicity to the early life history stages of the polychaete Arenicola marina in artificial seawater.

Publication ID: pub.1032566405

Publication date: 25/07/2014

Keywords: Animals; Carbon Dioxide; Copper; Devon; DNA Damage; Female; Fertility; Hydrogen-Ion Concentration; Life Cycle Stages; Male; Mothecombe Beach; Oceans and Seas; Polychaeta; Seawater; Sperm Motility; UK; Water Pollutants, Chemical

The speciation and therefore bioavailability of the common pollutant copper is predicted to increase within the pH range anticipated under near-future ocean acidification (OA), hence the potential exists for copper toxicity to marine organisms to also increase. We investigated the impact of OA (seawater pH values of 7.77 (pCO2 1400 μatm) and 7.47 (pCO2 3000 […]

Forecast cooling of the Atlantic subpolar gyre and associated impacts

Publication ID: pub.1035663758

Publication date: 21/07/2014

Keywords: Atlantic; Decadal Prediction; Impacts; Subpolar Gyre

Decadal variability in the North Atlantic and its subpolar gyre (SPG) has been shown to be predictable in climate models initialized with the concurrent ocean state. Numerous impacts over ocean and land have also been identified. Here we use three versions of the Met Office Decadal Prediction System to provide a multimodel ensemble forecast of […]

Eddy-induced variability in Southern Ocean abyssal mixing on climatic timescales

Publication ID: pub.1044330366

Publication date: 13/07/2014

Keywords: Abyssal Mixing; Atmospheric Forcing; Drake Passage; Eddy-induced Variability; Southern Ocean; Upper and Lower Cells

In the Southern Ocean, deep-water masses of the world ocean upwell to the surface and subsequently sink to intermediate and abyssal depths in two overturning cells. Observational evidence relates changes in abyssal mixing—a key influence on the lower cell—to oceanic eddy variability.

Effect of a Jurassic oceanic anoxic event on belemnite ecology and evolution

Publication ID: pub.1037442947

Publication date: 30/06/2014

Keywords: Animals; Aquatic Organisms; Biological Evolution; Carbon; Copenhagen; Denmark; Ecosystem; Fossils; Oceans and Seas; UK; Yorkshire

The Toarcian oceanic anoxic event (T-OAE; ∼ 183 million y ago) is possibly the most extreme episode of widespread ocean oxygen deficiency in the Phanerozoic, coinciding with rapid atmospheric pCO2 increase and significant loss of biodiversity in marine faunas. The event is a unique past tipping point in the Earth system, where rapid and massive […]
