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 ...
Planktonic world: First scientific results from the Tara Oceans expedition
When you mention rich ecosystems that are vital for life on Earth, people tend to think of rainforests, but ocean plankton are actually just as crucial. The microscopic beings that drift on the upper layer ...
Coexisting in a sea of competition: Similar diatom species seek out nutrients in different ways
Diversity of life abounds on Earth, and there's no need to look any farther than the ocean's surface for proof. There are over 200,000 species of phytoplankton alone, and all of those species of microscopic ...
Nutrient pollution damages streams in ways previously unknown, ecologists find
An important food resource has been disappearing from streams without anyone noticing until now.
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.
