Antarctica is not free from environmental pollutants although it is often perceived as the last pristine continent on Earth. Research stations represent one of the largest forms of anthropogenic activity…9 October, 2018 by Peter Convey
Fungi are microbes that play vital roles in nutrient cycling in natural environments and in symbiotic interactions with plants and other microbes. They thrive successfully even when challenged by various…6 October, 2018 by Claire Waluda, Jennifer Jackson, Jaume Forcada, Michael Dunn, Phil Trathan
Gentoo penguins Pygoscelis papua breed at a number of sites at the West Antarctic Peninsula, including Goudier Island, Port Lockroy—the longest studied location for tourist-penguin interactions in the Antarctic. These…1 October, 2018 by Andrew Kavanagh, Mark Clilverd, Richard Horne
We examine the variation of stratospheric ozone over northern Finland using ozonesonde observations from 1845 stratospheric balloon flights launched between 1989 and 2015 from near Sodankylä. The annual variation of…1 October, 2018 by Richard Horne
Predicting variations in the near-Earth space environment that can lead to spacecraft damage and failure is one example of “space weather” and a big space physics challenge. A project recently…1 October, 2018 by Richard Phillips
Albatrosses (Diomedeidae) are iconic pelagic seabirds whose life-history traits (longevity, high trophic position) put them at risk of high levels of exposure to methylmercury (MeHg), a powerful neurotoxin that threatens…1 October, 2018 by Richard Phillips
Given the rarity of hybridization in seabirds, which presumably relates to their very high philopatry, the degree of breeding‐site vagrancy should correspond with the incidence of mixed‐species pairing, although not…1 October, 2018 by Richard Phillips
Many predictive models of spatial and temporal distribution (e.g. in response to climate change or species introductions) assume that species have one environmental niche that applies to all individuals. However,…1 October, 2018 by Kevin Hughes, Kevin Newsham, Marta Misiak
The harsh climatic conditions and low levels of human activity in Antarctica, relative to other regions, means few non-native species have established. However, the risk of introductions is becoming greater…
