New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…
A new analysis of the changing character of runoff, river discharge and other hydrological cycle elements across the North Slope of Alaska reveals significant…

California coastal waters contain some of our nation's more economically valuable fisheries, including salmon, crabs and shellfish. Yet, these fisheries are…
A new paper to be published on 16 December provides a significant new insight into our understanding of uranium biogeochemistry and could help with the UK's…
After exchanging research teams and crewmembers, the greatest expedition to the Central Arctic of all time is now entering the next phase, during which…
High concentrations of CO2 in the atmosphere and the associated global warming are making us more and more aware of how imperative it is to preserve the carbon…
To shed new light on buffelgrass and the best techniques to use for its control, researchers from the University of Arizona conducted a literature review that…
Satellite data has given scientists clues about how, when and why Greenland's glaciers are shrinking – and shows a sharp increase in glacial retreat beginning…
“One of the suggestions for the continued rise in atmospheric methane, based on ground-based data, is that tropical sources have increased,” says Mark Lunt, an…
The Antarctic is one of the parts of earth that we know the least about. Due to the massive ice shield, the collection of geophysical information on site is…
Scientists estimate that summer sea ice in the Arctic Ocean will be largely gone within a generation. This is bad news for the world, as ice and snow reflect a…
We are living in the period of fastest urban growth in human history, with more than 2 billion additional people expected in cities by 2030 – a pace that is…

Plants grow throughout their entire life. This is due to a small structure at the tip of the plant’s shoots, known as the meristem. This is the control center…
RV Polarstern (86°N,121°E). The atmosphere of the central Arctic is polluted with fine dust from Siberia and North America. This was the result of a…
