In view of the wide range of estimates for the total primary production for the Southern Ocean south of the Subantarctic Front—current estimates range from 1.2 to 3.5 Gtonne C […]
A new method for retrieving the vertical profile of NO2 from ground-based measurements is applied to four months of measurements made at Aberdeen (57°N) during part of SESAME from November […]
Aims to describe petrography and geochemistry of calcite cements precipitated in species borings from the lower 180m of La Meseta Formation on island. Interprets data in terms of diagenetic history […]
The rise in metabolism following feeding exhibited by animals, known as the heat increment or specific dynamic action (SDA) of feeding has been well known since the 1930s when it […]
The British Antarctic Survey’s Antarctic Plant Database holds over 50,000 herbarium records for Antarctic and sub-Antarctic flowering plants and cryptogams held in herbaria world-wide. In addition, it holds information on […]
Field and earthquake data are presented which show that small faults can be important during block rotation. `Small’ here means those faults which are at least an order of magnitude […]
Marie Byrd Land, Antarctica, is a major part of the proto-Pacific supercontinental margin. On the basis of new geochronological and geochemical data relating to its pre-Jurassic evolution, Marie Byrd Land […]
A new multi-disciplinary study of the central Sierras Pampeanas encompasses fieldwork, petrography, metamorphic and micro-structural analysis, geochemistry and geochronology. Remnants of a low-to-medium grade metasedimentary sequence, which also occurs in […]
The field occurrence, age, classification and geochemistry of the Mesozoic volcanic rocks of Patagonia and West Antarctica are reviewed, using published and new information. Dominated by rhyolitic ignimbrites, which form […]
A basic background is presented for the discussion of the Early Palaeozoic geology of western Argentina covered by this book. This includes the definition and terminology of orogenic cycles on […]
In long-lived and monogamous species, with partners separated between breeding seasons, the previous mate usually returns and waiting is therefore rewarded, thus contributing to mate retention as an adaptive strategy. […]
