Three components of the survival strategy of a terrestrial Antarctic mite, Alaskozetes antarcticus (Acari: Cryptostigmata) are considered: overwintering survival, energetics and life history. Supercooling is an important feature of its […]
Field mapping and structural studies in northern Sierra Leone by an I.G.S. team have established a stratigraphic sequence in this part of the Archaean of the West African Craton. An […]
An energy balance survey was conducted on an Antarctic base on 12 individuals for periods varying between 6 and 12 months. Energy expenditure was estimated using two activity/dairy card techniques […]
A dietary survey was carried out on an Antarctic base over a period of 6 to 12 months on twelve individuals. Three methods of determining individual food and energy intake […]
Body weight and body fat changes (calculated from skinfold thickness) that occurred in a male population spending a year on an Antarctic base are described. There was a marked individual […]
Teleost fish scales play important roles in animal protection and homeostasis. They can be targeted by endogenous estrogens and by environmental estrogenic endocrine disruptors. The phytoestrogen genistein is ubiquitous in […]
Investigation of organic compounds in ice cores can potentially unlock a wealth of new information in these climate archives. We present results from the first ever ice core drilled on […]
1. Biodiversity loss has increased globally in recent years. The major threat to Antarctica’s unique terrestrial biodiversity is the establishment of non-native species. Nonetheless, while preventing the introduction of non-native […]
Snow thickness measurements over relatively smooth Arctic first-year sea ice, obtained near Cambridge Bay, Nunavut, Canada (2014, 2016 and 2017) and near Elson Lagoon, Alaska, USA (2003 and 2006), are […]
We present first observations of OH and (HO2 + RO2) carried out in Antarctica outside the summer season. Measurements were made over 23 days in spring at the coastal Antarctic […]
Myctophid fish are the most abundant and diverse mesopelagic fishes in the Southern Ocean. They are a conduit of energy between primary consumers and higher marine predators, and between the […]
