Rb-Sr whole-rock isochron evidence for the age of the Malvern Hills complex
Read more of: Rb-Sr whole-rock isochron evidence for the age of the Malvern Hills complexThe Malvernian igneous complex of the Malvern Hills consists mainlyof plutonic rocks and their locally deformed equivalents. The igneous rocks are calc-alkaline and range from ultra mafic diorite to granite […]

Population ecology of a terrestrial isopod in two breckland grass heaths
Read more of: Population ecology of a terrestrial isopod in two breckland grass heaths(1) Two superficially similar chalk grasslands in the Breckland of East Anglia provided very different habitats for the abundant terrestrial isopod Armadillidium vulgare (Latreille). At Lakenheath Warren the site was […]

Altitudinal gradients in Magellanic sub-Antarctic lagoons: the effect of elevation on freshwater macroinvertebrate diversity and distribution.
Read more of: Altitudinal gradients in Magellanic sub-Antarctic lagoons: the effect of elevation on freshwater macroinvertebrate diversity and distribution.Background. The study of altitudinal gradients provides insights about species diversity, distribution patterns and related drivers. The Magellanic sub-Antarctic ecoregion has a steep elevational gradient, peaking at around 1,000 m […]

Antarctic Futures: An Assessment of Climate-Driven Changes in Ecosystem Structure, Function, and Service Provisioning in the Southern Ocean
Read more of: Antarctic Futures: An Assessment of Climate-Driven Changes in Ecosystem Structure, Function, and Service Provisioning in the Southern OceanIn this article, we analyze the impacts of climate change on Antarctic marine ecosystems. Observations demonstrate large-scale changes in the physical variables and circulation of the Southern Ocean driven by […]

Habitat partitioning in Antarctic krill: Spawning hotspots and nursery areas
Read more of: Habitat partitioning in Antarctic krill: Spawning hotspots and nursery areasAntarctic krill, Euphausia superba, have a circumpolar distribution but are concentrated within the south-west Atlantic sector, where they support a unique food web and a commercial fishery. Within this sector, […]
