Biogeography and Regional Classifications of Antarctica
In this chapter we refer to the ‘Antarctic’ in its widest sense. On land, we include the Antarctic continent and Peninsula, the various archipelagos of the Scotia arc, and the […]

Southern Ocean Deep Benthic Biodiversity
Read more of: Southern Ocean Deep Benthic BiodiversityThe deep sea is the largest environment on the planet, the least well known and one of the least studied. It contains extremely large habitats, and millions of km2 of […]

Mechanisms Defining Thermal Limits and Adaptation in Marine Ectotherms: An Integrative View
Read more of: Mechanisms Defining Thermal Limits and Adaptation in Marine Ectotherms: An Integrative ViewIt is widely accepted that marine biogeography is largely shaped by direct effects of temperature (Angel, 1991; Murawski, 1993). Temperature also influences biodiversity patterns at various latitudes (e.g.,Royet al.,1998; Astorga […]

Environmental Forcing and Southern Ocean Marine Predator Populations
Read more of: Environmental Forcing and Southern Ocean Marine Predator PopulationsThe Southern Ocean (Figure 11.1) is a major component within the global ocean and climate system. It not only unites the Atlantic Ocean with the Indian and Pacific Oceans, but […]

The Dynamic Mosaic Disturbance and Development of Antarctic Benthic Communities
Read more of: The Dynamic Mosaic Disturbance and Development of Antarctic Benthic CommunitiesThe continental shelf is the platform for many of the planet’s most productive ecosystems but it is exposed to high disturbance. At high latitudes, massive grounded ice sheets have extended […]

Spatial and Temporal Operation of the Scotia Sea Ecosystem
Read more of: Spatial and Temporal Operation of the Scotia Sea EcosystemAnalysis of the operation of ocean ecosystems requires an understanding of how the structure of the ecosystem is determined by interactions between physical, chemical and biological processes. Such analysis needs […]

The impact of regional climate change on the marine ecosystem of the western Antarctic Peninsula
Read more of: The impact of regional climate change on the marine ecosystem of the western Antarctic PeninsulaThe Antarctic Peninsula is one of three areas of the globe currently experiencing rapid regional climate change (King, 1994; Smith et al., 1996, King & Harangozo, 1998; Vaughan et al., […]

Antarctic Lakes as Models for the Study of Microbial Biodiversity, Biogeography and Evolution
Read more of: Antarctic Lakes as Models for the Study of Microbial Biodiversity, Biogeography and EvolutionThe Antarctic continent is almost entirely covered by a vast icecap that reaches 4 km in thickness. Despite this, the continent possesses a remarkable array of lake ecosystems, many of […]

The ice thickness distribution of Flask Glacier, Antarctic Peninsula, determined by combining radio-echo soundings, surface velocity data and flow modelling
Read more of: The ice thickness distribution of Flask Glacier, Antarctic Peninsula, determined by combining radio-echo soundings, surface velocity data and flow modellingAn interpolated bedrock topography is presented for Flask Glacier, one of the tributaries of the remnant part of the Larsen B ice shelf, Antarctic Peninsula. The ice thickness distribution is […]

Continental governance and environmental management mechanisms under the Antarctic Treaty System: sufficient for the biodiversity challenges of the this century?
Read more of: Continental governance and environmental management mechanisms under the Antarctic Treaty System: sufficient for the biodiversity challenges of the this century?Antarctic terrestrial biodiversity is challenged by rapid climatic changes and expansion of the human footprint. As well as the potential for environmental damage at the local level, these challenges are […]

Microdistribution of faunal assemblages at deep-sea hydrothermal vents in the Southern Ocean
Read more of: Microdistribution of faunal assemblages at deep-sea hydrothermal vents in the Southern OceanChemosynthetic primary production by microbes supports abundant faunal assemblages at deep-sea hydrothermal vents, with zonation of invertebrate species typically occurring along physico-chemical gradients. Recently discovered vent fields on the East […]
