Krill in the Southern Ocean are projected to decline about 30% this century, due to human-driven climate change. But natural variability also plays a role. A new study tries to tease out the difference.
(University of Liege) Lake Victoria, which came under the spotlight in 2004 by the documentary “Darwin’s nightmare”, is not only suffering from the introduction and commercialisation of the Nile perch. A study lead researchers from the University of Liège (Belgium) has highlighted other worrying phenomena, particularly climatic ones, which have an equally important impact on the quality of the lake’s waters.
(Binghamton University) Binghamton University anthropologists Robert DiNapoli and Carl Lipo received a $60,280 grant from the National Geographic Society’s Committee for Research and Exploration to explore how ancient populations managed freshwater scarcity.
(University of Missouri-Columbia) Researchers from the University of Missouri and the United States Geological Survey are using a grant from the USGS Aquatic Invasive Species Competitive Grants Program to develop a 3D model to better predict how the variable dynamics of river water flows — currents and water turbulence — influence the spread of invasive carp throughout the U.S. Invasive carp reproduce in rivers, and can lay thousands of eggs that can drift for miles in river flows before hatching.
Although people in industrialized nations have access to modern medical care, they are more sedentary and eat a diet high in saturated fats. In contrast, the Tsimane have little or no access to health care but are extremely physically active and consume a high-fiber diet that includes vegetables, fish, and lean meat. “The Tsimane have […]

(University of Colorado at Boulder) New research about the fate of krill–one of the most abundant species on Earth–during this century has important implications for not only the Antarctic food web, but for the largest commercial fishery in the Southern Ocean.
It’s the decade of ocean science, and one in which we must get on track for net-zero by 2050. Two World Economic Forum events discussed the massive challenges ahead. Marine biologist Nina Jensen joins Radio Davos to pick some highlights….
Global oceans absorb about 25% of the carbon dioxide released into the atmosphere. Electricity-eating bacteria known as photoferrotrophs could provide a boost to this process, helping reduce emissions, according a new study. The study found the bacteria can “eat” electricity…
Some environmental solutions are win-win, helping to rein in global warming and protecting biodiversity, too. But others address one crisis at the expense of the other. Growing trees on grasslands, for example, can destroy the plant and animal life of…
