Sardine cycles, krill declines, and locust plagues: revisiting ‘wasp-waist’ food webs
Read more of: Sardine cycles, krill declines, and locust plagues: revisiting ‘wasp-waist’ food webs‘Wasp-waist’ systems are dominated by a mid trophic-level species that is thought to exert top-down control on its food and bottom-up control on its predators. Sardines, anchovy, and Antarctic krill […]

Modelled trends in Antarctic sea ice thickness
Read more of: Modelled trends in Antarctic sea ice thicknessUnlike the rapid sea-ice losses reported in the Arctic, satellite observations show an overall increase in Antarctic sea ice concentration over recent decades. However, observations of decadal trends in Antarctic […]

Colony attendance and at-sea distribution of thin-billed prions during the early breeding season
Read more of: Colony attendance and at-sea distribution of thin-billed prions during the early breeding seasonProcellariiform seabirds have extreme life histories; they are very long-lived, first breed when relatively old, lay single egg clutches, both incubation and chick-rearing are prolonged and chicks exhibit slow growth. […]

Permafrost and snow monitoring at Rothera Point (Adelaide Island, Maritime Antarctica): implications for rock weathering in cryotic conditions.
Read more of: Permafrost and snow monitoring at Rothera Point (Adelaide Island, Maritime Antarctica): implications for rock weathering in cryotic conditions.In February 2009 a new permafrost borehole was installed close to the British Antarctic Survey Station at Rothera Point, Adelaide Island (67.57195°S 68.12068°W). The borehole is situated at 31 m […]

Sea salt as an ice core proxy for past sea ice extent: a process-based model study
Read more of: Sea salt as an ice core proxy for past sea ice extent: a process-based model studySea ice is a reflection of, and a feedback on the Earth’s climate. We explore here, using a global atmospheric chemistry-transport model, the use of sea salt in Antarctic ice […]

Deep sequencing of the mantle transcriptome of the great scallop Pecten maximus
Read more of: Deep sequencing of the mantle transcriptome of the great scallop Pecten maximusRNA-Seq transcriptome data were generated from mantle tissue of the great scallop, Pecten maximus. The consensus data were produced from a time course series of animals subjected to a 56-day […]

Species versus guild level differentiation revealed across the annual cycle by isotopic niche examination
Read more of: Species versus guild level differentiation revealed across the annual cycle by isotopic niche examinationSummary 1.Interspecific competitive interactions typically result in niche differentiation to alleviate competition through mechanisms including character displacement. However, competition is not the sole constraint on resource partitioning, and its effects […]

Modeling Antarctic tides in response to ice shelf thinning and retreat
Read more of: Modeling Antarctic tides in response to ice shelf thinning and retreatTides play an important role in ice sheet dynamics by modulating ice stream velocity, fracturing, and moving ice shelves and mixing water beneath them. Any changes in ice shelf extent […]

Investigating vegetation-climate feedbacks during the early Eocene
Read more of: Investigating vegetation-climate feedbacks during the early EoceneEvidence suggests that the early Eocene was a time of extreme global warmth. However, there are discrepancies between the results of many previous modelling studies and the proxy data at […]

Limpet feeding rate and the consistency of physiological response to temperature
Read more of: Limpet feeding rate and the consistency of physiological response to temperatureThermal reaction norms are fundamental relationships for geographic comparisons of organism response to temperature. They are shaped by an organism’s environmental history and provide insights into both the global patterns […]
