Sequencing reveals complex history of amphibian-killing fungus
Harvesting of small fish species should be cut: study
Algal antifreeze makes inroads into ice
the important first rung of the food web each spring in places like the Arctic Ocean can engineer ice to its advantage, according to the first published findings about this ability.
The great pond experiment: Pond communities bear lasting imprint of random events in their past
(PhysOrg.com) -- A seven-year experiment shows that pond communities bear the imprint of random events in their past, such as the order in which species were introduced into the ponds. This finding locates ...
Sea creatures will get bigger and bigger (if we don't eat them first)
When life on Earth began around 3.6 billion years ago, all organisms were small. Indeed, it took some 2.5 billion years to evolve any organism that grows larger than a single cell.
Sizing up giants under the sea: Team corrects inaccuracies, elucidates measurements for 25 marine species
A team of scientists and undergraduate students have analyzed the body size for 25 marine species, including whales, sharks, squids, and other ocean giants. The project elucidates both the challenges of arriving ...
Ecosystems need maths not random nature to survive
A previously unknown mathematical property has been found to be behind one of nature's greatest mysteries – how ecosystems survive.
Biologist addresses ways in which management efforts can shape predator-prey interactions
A sex-changing fish called California sheephead (Semicossyphus pulcher) plays a vital role in the food web of kelp forests along the Pacific coast. Commonly found in the waters from Baja California to Poi ...
A better way to find communities in networks
A key challenge network scientists face is figuring out how networks break down into communities—for example, different groups of friends in a high school social network or species in a food web.
Researchers find selective eaters less likely to be eaten
New research has found that dietary specialization among herbivores, specifically caterpillars, indicates whether or not they are better able to hide themselves from predators such as birds. The research ...
Concerns raised over EU ban on ditching unwanted fish
New rules banning fishermen from throwing away unwanted fish they have caught could harm wildlife – and fail to improve fish stocks, a University of Strathclyde report has found.
Not so dirty: Methane fuels life in pristine chalk rivers
Scientists from Queen Mary University of London have found that naturally high concentrations of the greenhouse gas methane contributes to energy production in chalk rivers, in a new study published today ...
Ancient food webs developed modern structure soon after mass extinction
Researchers from the Santa Fe Institute and the Smithsonian Institution have pieced together a highly detailed picture of feeding relationships among 700 mammal, bird, reptile, fish, insect, and plant species ...
Computer model predicts vastly different ecosystem in Antarctica's Ross Sea in the coming century
The Ross Sea, a major, biologically productive Antarctic ecosystem, "clearly will be extensively modified by future climate change" in the coming decades as rising temperatures and changing wind patterns ...
