Polar research: Six priorities for Antarctic science DDT, known for accumulating in food webs and persisting for decades in soil and river sediment, was banned in the United States in 1972. Government Officials May Have Mishandled DDT Superfund Site 2014-08-06T04:00:00Z “If that part of the food web is in decline, there may be a food problem for some birds,” he said. Once-common marine birds disappearing from our coast 2014-07-24T04:00:00Z Because ocean phytoplankton – microscopic plants sustaining the marine food web – cannot get enough iron, there is a limit to the carbon dioxide they can absorb from the atmosphere. Desert Dust Feeds Deep Ocean Life 2014-07-16T04:00:00Z The project they worked on was part of a unit on food chains and food webs that Stamm taught in her three science classes in May. Science students aren’t afraid to get hands dirty 2014-05-24T04:00:00Z Dr. Bertness and his colleagues wondered how fishing and crabbing were affecting the food webs of the salt marshes.

Octopuses Make Food for Weird Critters 2014-01-02T04:45:03.296Z The loss of a predator, Nijhuis reminds us, “causes a boom in its prey — and a consequent power shift that’s felt throughout the food web.” The Best Animal Stories of 2013 2013-12-31T18:15:02.455Z Change at the base of the food web "What's groundbreaking about our research is that there's been this huge change at the base of the food web that corresponds with these climate drivers," Sherwood said. Climate Change Tweaks Pacific Ocean Chemistry 2013-12-17T16:45:00.776Z This is a slight misnomer as the area is not completely dead although the lower oxygen levels do threaten large portions of the aquatic food web. Dead Zone Judo 2013-10-10T19:46:32.923Z But there are still few ecological time series, in particular species-level data for the plankton that form the base of marine food webs. Ocean sciences: Follow the fish 2013-10-09T17:20:29.310Z Plankton, a critical source of food for whales, tuna and numerous other fish, will be the first organism affected by the changing current, altering the composition and dynamics of the food web.

Sea Change: How Can We Help Oceans Recover? 2013-08-16T12:45:00.507Z The release of carbon into the atmosphere, caused by humans’ burning of fossil fuels, is in turn adding carbon to the ocean, changing its chemistry and endangering entire marine food webs. Baby Oysters In 'Death Race' With Acidifying Oceans 2013-07-26T12:45:00Z And they also, and perhaps most pertinently from the human point of view, found evidence for one other part of such a food web: the decomposers. Marine ecology: Welcome to the plastisphere 2013-07-18T15:04:03Z Abalone play an important role in subtidal benthic marine ecosystems; without them a crucial part of the marine food web will potentially be lost forever. Southern California and Endangered Abalone Populations 2013-07-04T15:45:00.487Z "I think we should care about this because invertebrates are an important part of the food web." Pesticides Spark Broad Biodiversity Loss 2013-06-18T21:15:00.150Z Rather, they've assumed that the abundance on any given floor of the food web is determined mainly by the supply of nutrients from the floors below, and not by the impact of consumers up above. Sea Change: How Can We Help Oceans Recover? 2013-08-16T12:45:00.507Z The scourge also affects tiny plankton that are the base of the food web that produces prized Alaskan salmon. Baby Oysters In 'Death Race' With Acidifying Oceans 2013-07-26T12:45:00Z That means parasites don't show up in food webs, the maplike visualizations of who-eats-who that students often learn about in high school biology. ScienceShot: Food Web, Meet Parasite 2013-06-11T22:00:00Z As abalone have begun to decrease in numbers the health of coastal food webs has deteriorated as well. Southern California and Endangered Abalone Populations 2013-07-04T15:45:00.487Z Richard Merrick, director of scientific programs and chief science adviser for National Oceanic and Atmospheric Administration Fisheries, said warming seas affect not only sea creatures, but also the food web on which they depend. World’s fish have been moving to cooler waters for decades, study finds 2013-05-15T17:00:00Z Also, in a lot of oceanic ecosystems, many different consumers feast on any given floor of the food web. Sea Change: How Can We Help Oceans Recover? 2013-08-16T12:45:00.507Z Without robust soil ecosystems, the world’s food web would be in trouble. News Analysis: The Hidden World of Soil Under Our Feet 2013-05-11T16:09:46Z And the other big effect of CO2 emissions release, ocean acidification, threatens the corals that are essential to the ocean food web – a food web already under pressure from human overfishing.

Long-lasting Chemicals May Harm Sea Turtles 2013-03-14T15:15:00.817Z Tiedje said the fish – and consequently the eagles, seabirds and the rest of the food web – may remain contaminated for a long time, since fish are “good scavengers.” The Mystery of the Vanishing DDT in the Ocean Near Los Angeles 2013-03-13T15:15:03.327Z As groundfish numbers fell, their prey—herring, capelin, and sand lance—surged, causing a decline in zooplankton and an expansion of phytoplankton: a cascade through four full stories of the food web. Sea Change: How Can We Help Oceans Recover? 2013-08-16T12:45:00.507Z And, day by day, the international food web grows ever more complicated. Everything you never wanted to know about the European horse meat scandal 2013-02-19T17:46:00Z This puts a mesopredator a sort of “hub” position within its food web. Laikipia Plateau: What is a Mesopredator? 2013-02-17T17:45:00.253Z Concentrations of the five most abundant PFCs in these turtles are related to their different levels on the food web, with decreasing concentrations beginning with Kemp’s ridley, then loggerhead, leatherback and green turtles. Long-lasting Chemicals May Harm Sea Turtles 2013-03-14T15:15:00.817Z So studying the interactions between these species might allow scientists to detect changes in marine food webs. The light fantastic: Harnessing Nature's glow 2013-01-24T00:39:57Z But the groundfish's failure to recover, it now appears, does not necessarily implicate a decadal switch, because it can also result from the inner-workings of a food web. Sea Change: How Can We Help Oceans Recover? 2013-08-16T12:45:00.507Z As United Nations delegates end their mercury treaty talks today, scientists warn that ongoing emissions are more of a threat to food webs than the mercury already in the environment. Mercury Emissions Threaten Aquatic Environments 2013-01-18T16:15:03.737Z Their loss can initiate what Paine would later call trophic cascades — the rise and fall of connected species throughout the food web. The Man Whose Dynasty Changed Ecology 2013-01-16T18:15:00.270Z Analysis showed that species of mistletoe play an important role in moving nutrients around the forest food web.

Green Blog: In the Dark Cave, Fearsome Living Fossils 2012-10-09T16:57:49Z The rich food web that supports humpback whales that feed in and around the Stellwagen Bank National Marine Sanctuary draws other predators like haddock and cod, too, which are targets of area fisheries. Green Blog: Managing the Ocean for Humans and Whales 2012-08-22T10:00:09Z The presence of some shark species as 'apex predators' - occupying the very top level of the food web - is actually an indication of a healthy marine environment. IHT Rendezvous: Should Great White Sharks Remain Protected? 2012-08-13T05:02:54Z “They are at the top of the aquatic food web and concentrations of bioaccumulative compounds tend to be highest in such species.” Great Lakes Trout Serve as Barometer for Global Pollutants 2012-08-02T16:45:00.217Z They persist in soil and sediment for decades, perhaps centuries, and are locked away in the fatty tissues of animals, building up in food webs. Pollution, Poverty and People of Color: Dirty Soil and Diabetes 2012-06-13T20:15:00.237Z We hope that our research in the kipuka — forest islands in the fields of lava — will yield new insights into how forest patch size and introduced rats influence food webs and native birds.

Invasive Species Target of New Ballast Water Rule 2012-04-07T19:09:22Z It cited reptiles, birds and “mammalian wildlife that represent essential components of the food web.” Green Blog: Uranium, Cattle Grazing and Risks Unknown 2012-04-04T19:40:12Z Indeed, it's hard at this point to extrapolate the effect to the entire food web, Smith says. Life Blooms Under Arctic Ice 2012-06-07T21:05:00Z Although radioactive iodine would move up the food web, it would be decaying at the same time that it is being concentrated, so it would be gone from the fish within days. Radioactive Iodine from Fukushima Found in California Kelp 2012-03-30T16:45:00.263Z Still, it is clear that mercury is bring mobilized into the food web, Dr. Weiss-Penzias said. Green Blog: Coastal California Fog Carries Toxic Mercury, Study Finds 2012-03-28T16:58:37Z The two food webs below show predatory relationships among life-forms in the northern Adriatic Sea.

Life Blooms Under Arctic Ice 2012-06-07T21:05:00Z He is interested in squid because they represent something of a keystone species in the ocean, sitting right at the heart of many food webs. Eavesdropping on the squid world 2012-02-26T01:59:14Z “It is the first time that the roles of humans as predators are explicitly compared to the roles of other predators in food webs.” No Omnivore’s Dilemma for Alaskan Hunter-Gatherers 2012-02-19T22:26:13Z What is more, the organisms living in the alien environment thrive on chemical-based food webs rather than on photosynthesis. Green Blog: Amid Dark Vents in the Depths, Something Stirs 2012-01-04T12:30:18Z Wolves are “apex predators, on top of the food web,” Ripple said.

No Omnivore’s Dilemma for Alaskan Hunter-Gatherers 2012-02-19T22:26:13Z Corals, of course, aren’t the only marine organisms implicated: Krill, a crucial fabric of the marine food web, are also under threat. The Great Barrier Reef, RIP? 2011-10-12T00:22:01Z Along with 150 high-magnification photographs, Kirby's book explains how rising sea surface temperatures due to anthropogenic climate change will alter the sea's food web and the ecology of Earth. Secret Lives of Plankton Revealed in Microscopic Glory 2011-09-12T13:45:00.227Z Let me spoil it for you: it is a chemical cue pervasive throughout the marine food web that also affects the earth’s climate. Chemistry Day at Scientific American Blog Network 2011-08-02T17:45:00.247Z This is a problem because the tight interconnectivity of food webs means that any hiccup, like a decrease in anchovy population, can destabilize everything above and below it. Fish Food Chain Flounders -- and Finds Its Way Back 2011-07-30T06:30:30Z Christopher S. Ellings, a salmon research biologist with the Nisqually Indian Tribe, said any of the changes — on its own — could significantly alter the local food web. Seeing Trends, Coalition Works to Help a River Adapt 2011-07-20T17:20:45Z They affect food webs by capturing plankton that would otherwise be eaten by fish, and converting that food energy into gelatinous biomass. Jellyfish Blooms Transfer Food Energy From Fish to Bacteria 2011-06-09T14:38:00Z These explosions of stinging swarms might also be doing some major disruption to marine food webs, according to a study published online June 6 in . Excessive Jellyfish Excrement Boosts Bacteria, Stings Fish Populations 2011-06-07T22:15:00.557Z So, to answer that, you have to first understand the chemistry, biology, and their impact on the food web. A True Duck Hunt: interview with Donovan Hohn 2011-05-02T16:15:03.843Z Now, in the first study of its kind, researchers have pinpointed early warning signs for the disruption of a food web in a lake. An Early Warning Sign for Ecosystem Collapse? 2011-04-28T20:02:09Z In particular, rapid swings in the density of plants and fleas indicated the food web was unstable and about to change. Boom and bust flags eco-collapse 2011-04-28T18:17:47Z "Marine bacteria typically play a key role in recycling carbon, nitrogen, phosphorus and other by-products of organic decay back into the food web," says Condon. Jellyfish Blooms Transfer Food Energy From Fish to Bacteria 2011-06-09T14:38:00Z That means less food for fish and other higher-level animals, potentially shifting the distribution of predators in the food web. Excessive Jellyfish Excrement Boosts Bacteria, Stings Fish Populations 2011-06-07T22:15:00.557Z "It will take decades to understand the full extent of impacts of this oil on niches in the food web."

Boat turbulence kills zooplankton 2011-04-19T08:32:56Z This means the carbon is lost as a direct source of organic energy for transfer up the food web. Jellyfish Blooms Transfer Food Energy From Fish to Bacteria 2011-06-09T14:38:00Z Still, Trivelpiece is confident that much of the West Antarctic Peninsula’s marine food web is unraveling. Penguin Declines May Come Down to Krill 2011-04-12T17:49:00Z Each summer, an explosion of tiny ocean-dwelling plants and algae, called phytoplankton, anchors the Arctic food web. Shifting spring: Arctic plankton blooming up to 50 days earlier now 2011-03-06T23:39:03Z Carpenter and his colleagues report online today inScience that these fluctuations were a warning that the lake's food web is changing. An Early Warning Sign for Ecosystem Collapse? 2011-04-28T20:02:09Z “The whole food web becomes bollixed when you take out the top-level predator.” Soup Without Fins? Some Californians Simmer 2011-03-05T23:04:34Z When it's not busy consuming cadavers, the hagfish's larger role in the food web remains a mystery, he says, as it's difficult to study fish that live this deep in the ocean. Hagfish Just Got More Disgusting 2011-03-02T22:05:00Z This shift in the balance of the food web isn't healthy or sustainable, the researchers argue. As Tuna Vanish, Sardines Rise 2011-02-18T23:24:25Z So the disrupted phytoplankton blooms could "have cascading effects up the food web all the way to marine mammals." Shifting spring: Arctic plankton blooming up to 50 days earlier now 2011-03-06T23:39:03Z Christensen says that we're essentially fishing down the food web—removing the large predatory fish, which allows the smaller ones to proliferate undisturbed. Why the World's Fisheries Are Going Bankrupt 2011-02-18T22:32:27Z The world's most common small freshwater feeder—gobbling up algae in lakes and ponds the world over—Daphnia are also a staple in fishes' diets, proving a crucial link in food webs. Copious Genes of Tiny Water Flea Promise a Leap in Understanding Environmental Toxins 2011-02-04T00:15:06.337Z Gardens rich in pollinators not only support the food web but also attract a wide variety of creatures, including birds and bats, to our gardens. Cultivating a healthier Seattle, one garden at a time 2011-02-01T00:26:50Z The researchers, led by Villy Christensen of the University of British Columbia in Canada, analyzed models of about 200 food webs around the world. As Tuna Vanish, Sardines Rise 2011-02-18T23:24:25Z But the Arctic food web is poorly studied, and so any resulting decline in fish, seabirds and mammals will be difficult to spot. Shifting spring: Arctic plankton blooming up to 50 days earlier now 2011-03-06T23:39:03Z They compared the dynamics of financial interactions with other complex networks such as ecological food webs and the spread of diseases. Nature's lessons for bank crises 2011-01-19T20:00:43Z Selenium builds up in animal tissues, so higher up the food web end up with more in their systems. EPA Set to Regulate Wastewater from Coal-Fired Power Plants 2011-01-10T07:46:38.200Z In particular, he notes, recent evidence suggests fisheries do not necessarily begin by targeting fish higher up on the food web, but often simply pursue the most economically valuable species, regardless of their position. What's the Catch? Researchers Wrangle Over How to Measure Commercial Fishing's Impact on Ocean Biodiversity 2011-01-04T16:18:14.427Z While hydrocarbons are organic compounds that will eventually break down over time, the staying power and long-term impacts of heavy metals like vanadium and nickel in the food web are unknown. Scientists Study Impact of Gulf Oil Spill on Marine Food Webs 2010-12-28T16:16:00Z "Understanding the dynamics of deep-sea food webs is essential for scientific understanding and management of earth's largest ecosystem," Sutton said.
