Systematic conservation planning for Antarctic research stations.

The small ice-free areas of Antarctica are essential locations for both biodiversity and scientific research but are subject to considerable and expanding human impacts, resulting primarily from station-based research and support activities, and local tourism. Awareness by operators of the need to conserve natural values in and around station and visitor site footprints exists, but the cumulative nature of impacts often results in reactive rather than proactive management. With human activity spread across many isolated pockets of ice-free ground, the pathway to the greatest reduction of human impacts within this natural reserve is through better management of these areas, which are impacted the most.

Combating ecosystem collapse from the tropics to the Antarctic.

Globally, collapse of ecosystems-potentially irreversible change to ecosystem structure, composition and function-imperils biodiversity, human health and well-being. We examine the current state and recent trajectories of 19 ecosystems, spanning 58° of latitude across 7.7 M km , from Australia's coral reefs to terrestrial Antarctica.

An analysis of environmental incidents for a national Antarctic program.

Research stations in Antarctica are concentrated on scarce ice-free habitats. Operating these stations in the harsh Antarctic climate provides many challenges, including the need to handle bulk fuel and cargo increasing the risk of environmental incidents. We examined 195 reports of environmental incidents from the Australian Antarctic Program, spanning six years, to investigate the impacts and pathways of contemporary environmental incidents.

Vascular surgical society of great britain and ireland: patients with a failed infrainguinal bypass graft have abnormal lipid metabolism.

BACKGROUND: Dyslipidaemias adversely affect vascular tone, endothelial function and platelet activation. Abnormal lipid metabolism has not been established as a risk factor for infrainguinal bypass graft failure. Lipid metabolism was evaluated prospectively in patients with patent and occluded grafts.

Human or not? A problem in skeletal identification.

Frequently, bones submitted to physical anthropologists by law emforcement agencies as human prove to be nonhuman. This results in a waste of time, money, and effort of all concerned. A course has been designed that could be offered by a physical anthropologist either as a workshop or as part of a training program for law enforcement officers.
