Rapid subsurface warming and circulation changes of Antarctic coastal waters by poleward shifting winds
The southern hemisphere westerly winds have been strengthening and shifting poleward since the 1950s. This wind trend is projected to persist under continued anthropogenic forcing, but the impact of the changing winds on Antarctic coastal heat distribution remains poorly understood. Here we show that a poleward wind shift at the latitudes of the Antarctic Peninsula can produce an intense warmin...
متن کاملShifting gears: assessing collateral impacts of fishing methods in US waters
the deployment of excessive levels of fishing effort – is one of the most pressing problems for fisheries around the world (Pauly et al. 2002; Myers and Worm 2003). While attempts to address this problem continue at a single-species level, an ecosystem-based approach to fisheries management is necessary to understand the overall impacts of fishing (Dayton et al. 1995; Pitcher and Pauly 1998).

متن کاملShifting Sugars and Shifting Paradigms
No organism lives in a constant environment. Based on classical studies in molecular biology, many have viewed microbes as following strict rules for shifting their metabolic activities when prevailing conditions change. For example, students learn that the bacterium Escherichia coli makes proteins for digesting lactose only when lactose is available and glucose, a better sugar, is not. However...

متن کاملShifting depression
Biological studies into antidepressant drug action and into the aetiology of depression were highly active areas of research in the 1960s and 1970s but, arguably, have now lost some of their impetus and direction. Many investigations seem to have come to a natural end and there is a need for the subject to make a quantum leap to promote its development. It is recognized however, that advances h...
