Data from: Contrasting responses of male and female foraging effort to year-round wind conditions

Sue Lewis, Richard A. Phillips, Sarah J. Burthe, Sarah Wanless & Francis Daunt
1. There is growing interest in the effects of wind on wild animals, given evidence that wind speeds are increasing and becoming more variable in some regions, particularly at temperate latitudes. Wind may alter movement patterns or foraging ability, with consequences for energy budgets and, ultimately, demographic rates. 2. These effects are expected to vary among individuals due to intrinsic factors such as sex, age or feeding proficiency. Furthermore, this variation is predicted to become...

Data from: The influence of preceding dive cycles on the foraging decisions of Antarctic fur seals

Takashi Iwata, Kentaro Q. Sakamoto, Ewan W. J. Edwards, Ian J. Staniland, Philip N. Trathan, Yusuke Goto, Katsufumi Sato, Yasuhiko Naito & Akinori Takahashi
The foraging strategy of many animals is thought to be determined by their past experiences. However, few empirical studies have investigated whether this is true in diving animals. We recorded three-dimensional movements and mouth-opening events from three Antarctic fur seals during their foraging trips to examine how they adapt their behaviour based on past experience—continuing to search for prey in the same area or moving to search in a different place. Each dive cycle was...

Data from: Evolutionary factors affecting the cross-species utility of newly developed microsatellite markers in seabirds

Yoshan Moodley, Juan F. Masello, Gopi K. Munimanda, Theresa L. Cole, Marco R. Thali, Rachael Alderman, Richard J. Cuthbert, Manuel Marin, Melanie Massaro, Joan Navarro, Richard A. Phillips, Peter G. Ryan, Cristián G. Suazo, Yves Cherel, Henri Weimerskirch, Petra Quillfeldt & Luciano Calderon
Microsatellite loci are ideal for testing hypotheses relating to genetic segregation at fine spatio-temporal scales. They are also conserved among closely related species, making them potentially useful for clarifying interspecific relationships between recently diverged taxa. However, mutations at primer binding sites may lead to increased nonamplification, or disruptions that may result in decreased polymorphism in nontarget species. Furthermore, high mutation rates and constraints on allele size may also with evolutionary time, promote an increase in...

Data from: Connectivity in the cold: the comparative population genetics of vent-endemic fauna in the Scotia Sea, Southern Ocean.

Christopher N. Roterman, Jon T. Copley, Katrin T. Linse, Paul A. Tyler & Alex D. Rogers
We report the first comparative population genetics study for vent fauna in the Southern Ocean using cytochrome C oxidase I and microsatellite markers. Three species are examined: the kiwaid squat lobster, Kiwa tyleri, the peltospirid gastropod Gigantopelta chessoia and a lepetodrilid limpet, Lepetodrilus sp. collected from vent fields 440 km apart on the East Scotia Ridge (ESR) and from the Kemp Caldera on the South Sandwich Island Arc, ~95 km eastwards. We report no differentiation...

W. James Grecian, Matthew J. Witt, Martin J. Attrill, Stuart Bearhop, Peter H. Becker, Carsten Egevang, Robert W. Furness, Brendan J. Godley, Jacob González-Solís, David Grémillet, Matthias Kopp, Amélie Lescroël, Jason Matthiopoulos, Samantha C. Patrick, Hans-Ulrich Peter, Richard A. Phillips, Iain J. Stenhouse & Stephen C. Votier
Upwelling regions are highly productive habitats targeted by wide-ranging marine predators and industrial fisheries. In this study, we track the migratory movements of eight seabird species from across the Atlantic; quantify overlap with the Canary Current Large Marine Ecosystem (CCLME) and determine the habitat characteristics that drive this association. Our results indicate the CCLME is a biodiversity hotspot for migratory seabirds; all tracked species and more than 70% of individuals used this upwelling region. Relative...

Data from: Dwarf brooder versus giant broadcaster: combining genetic and reproductive data to unravel cryptic diversity in an Antarctic brittle star

Quentin Jossart, Chester Sands & Mary A. Sewell
Poecilogony, or multiple developmental modes in a single species, is exceedingly rare. Several species described as poecilogenous were later demonstrated to be multiple (cryptic) species with a single developmental mode. The Southern Ocean is known to harbor a high proportion of brooders (Thorson's Rule) but with an increasing number of counter examples over recent years. Here we evaluated poecilogony versus crypticism in the brittle star Astrotoma agassizii across the Southern Ocean. This species was initially...

Data from: Quantifying Susceptibility of Marine Invertebrate Biocomposites to Dissolution in Reduced pH

Matthew Chadwick, Elizabeth M. Harper, Anaëlle Lemasson, John I. Spicer & Lloyd S. Peck
Ocean acidification threatens many ecologically and economically important marine calcifiers. The increase in shell dissolution under the resulting reduced pH is an important and increasingly recognised threat. The biocomposites that make up calcified hardparts have a range of taxon-specific compositions and microstructures, and it is evident that these may influence susceptibilities to dissolution. Here, we show how dissolution (thickness loss) under both ambient and predicted end-century pH (≈7.6) varies between seven different bivalve mollusc and...

Evidence for an Allee effect in a declining fur seal population

Rebecca Nagel, Claire Stainfield, Cameron Fox-Clarke, Camille Toscani, Jaume Forcada & Joseph Hoffman
Allee effects play an important role in the dynamics of many populations and can increase the risk of local extinction. However, some authors have questioned the weight of evidence for Allee effects in wild populations. We therefore exploited a natural experiment provided by two adjacent breeding colonies of contrasting density to investigate the potential for Allee effects in an Antarctic fur seal (Arctocephalus gazella) population that is declining in response to climate-change induced reductions in...

Electron Electromagnetic Ion Cyclotron diffusion coefficients calculated from Van Allen Probe observations

Johnathan Ross & Sarah Glauert
Electromagnetic Ion Cyclotron (EMIC) wave are important for the losses of ultra-relativistic electrons from the Earth's radiation belts. In this work, statistical EMIC diffusion coefficients are calculated from Van Allen Probe A observations of EMIC waves from the entire mission. The diffusion coefficient calculations include the observed L* and activity dependent distributions in plasma density and wave spectra so that the wave-particle interactions modelled are representative of those in the radiation belts. These diffusion coefficients...

Variation and correlation in the timing of breeding of North Atlantic seabirds across multiple scales

Katharine Keogan, Francis Daunt, Sarah Wanless, Richard Phillips, David Alvarez, Tycho Anker-Nilssen, Robert Barrett, Claus Bech, Peter Becker, Per-Arvid Berglund, Sandra Bouwhuis, Zofia Burr, Olivier Chastel, Signe Christensen-Dalsgaard, Sébastien Descamps, Tony Diamond, Kyle Elliott, Kjell Einar Erikstad, Mike Harris, Jonas Hentati-Sundberg, Martin Heubeck, Magdalene Langset, Svein Lorentsen, Heather Major, Mark Mallory … & Stephen Kress
Timing of breeding, an important driver of fitness in many populations, is widely studied in the context of global change, yet despite considerable efforts to identify environmental drivers of seabird nesting phenology, for most populations we lack evidence of strong drivers. Here we adopt an alternative approach, examining the degree to which different populations positively covary in their annual phenology to infer whether phenological responses to environmental drivers are likely to be (i) shared across...

Individual repeatability of avian migration phenology: a systematic review and meta-analysis

Kirsty Franklin, Malcolm Nicoll, Simon Butler, Ken Norris, Norman Ratcliffe, Shinichi Nakagawa & Jennifer Gill
Changes in phenology and distribution are being widely reported for many migratory species in response to shifting environmental conditions. Understanding these changes and the situations in which they occur can be aided by understanding consistent individual differences in phenology and distribution and the situations in which consistency varies in strength or detectability. Studies tracking the same individuals over consecutive years are increasingly reporting migratory timings to be a repeatable trait, suggesting that flexible individual responses...

Isis remotely-operated vehicle (ROV) bathymetry data in Marguerite Trough, Antarctica, from James Clark Ross cruise JR157, 2007

Julian Dowdeswell, Robert Larter, Riko Noormets, Gwyn Griffiths & Kelly Hogan
On cruise JR157 the Isis ROV was deployed on 15 dives in the Marguerite Trough area in January and February 2007. Dives 10 and 11 targeted a bedrock channel system on the inner continental shelf to investigate channel incision processes and the history of glaciation in the area. The plan was to map parts of the channel walls and thalweg, and then to use these data to locate the best coring sites within the channel...
