Foundational Concept Of Ecology Tested With Experiment

Acting through links between four trophic levels and across two ecosystems, purple loosestrife altered life in nearby ponds An elementary school science activity asks children who have each been assigned a wetland plant or animal to connect themselves with string and tape to other “organisms” their assigned plant or animal interacts with in some way. Once an ecosystem web has been created, the teacher describes an event that affects one “organism.” That...

[ Watch the Video ] redOrbit Staff & Wire Reports NASA officials announced on Thursday that an expedition they sponsored had uncovered a massive bloom of phytoplankton in the ice-capped waters of the Arctic Ocean -- a discovery which the U.S. space agency has called "as dramatic and unexpected as finding a rainforest in the middle of a desert." The findings, which came as part of Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment (ICESCAPE)...

Environmental change is the selective force that preserves adaptive traits in organisms and is a primary driver of evolution. However, it is less well known that evolutionary change in organisms also trigger fundamental changes in the environment. Yale University researchers found a prime example of this evolutionary feedback loop in a few lakes in Connecticut, where dams built 300 years ago in Colonial times trapped a fish called the alewife. In a study published May 23 in the journal...

Prey Distribution, Not Biomass, Key To Marine Food Chain
2012-05-03 03:30:03

A new study has found that each step of the marine food chain is clearly controlled by the trophic level below it — and the driving factor influencing that relationship is not the abundance of prey, but how that prey is distributed. The importance of the spatial pattern of resources — sometimes called “patchiness” — is gaining new appreciation from ecologists, who are finding the overall abundance of food less important than its density and ease of access to...

Discovery could lead to new methods for environmental remediation and speeding up chemical reactions A glow coming from the glassy shell of microscopic marine algae called diatoms could someday help us detect chemicals and other substances in water samples. And the fact that this diatom can glow in response to an external substance could also help researchers develop a variety of new, diatom-inspired nanomaterials that could solve problems in sensing, catalysis and environmental...

Zooplankton Among First To Show Evidence Of Exposure To Deepwater Horizon Oil
2012-03-23 05:24:35

Ryan Parson for Redorbit.com Oil remnants from the Maconda-1 oil field have been discovered in animals in the northern Gulf of Mexico. Zooplankton samples collected from the Gulf of Mexico have shown positive evidence of exposure to oil that may have directly originated from the Deepwater Horizon oil spill. The effects of the deadly British Petroleum R/V Deepwater Horizon oilrig explosion that took place on April 20, 2010, will more than likely be present for many years to come....

Phytoplankton Key to a Healthy Planet says Canada Research Chair at the Forefront of Phytoplankton Research Maria (Maite) Maldonado, Canada Research Chair in Phytoplankton Trace Metal Physiology at The University of British Columbia, has made understanding the intricacies of marine phytoplankton her life's work. These tiny, single-celled algae, which act as a natural sponge for carbon dioxide and are a critical part of the global carbon cycle, may play a key role in ensuring the health of...

Pacific Carbon Pump Speeds Up In Summer
2012-02-09 04:44:07

An international team of scientists led by University of Hawaiʻi at Mānoa oceanographer David Karl has documented a regular, significant and unexpected increase in the amount of particulate matter exported to the deep sea in the North Pacific Subtropical Gyre. They suspect the previously undocumented phenomenon may be a response to day length, a general phenomenon known as photoperiodism. Measuring the biological carbon pump Using 13 years of...

A salp is a barrel-shaped, free-floating tunicate (any living organism which has a saclike body enclosed in a thick membrane or tunic with two openings or siphons for the ingress and egress of water). It moves by contracting which pumps water through its body. The salp strains the water with internal feeding filters as it goes through the body. It consumes phytoplankton that are strained from the water. Salps are common throughout equatorial, temperate, and colder seas. They are most often...

The South American pilchard, Sardinops sagax, is a sardine of the Family Clupeidae, the only member of the genus Sardinops, found in the indo-Pacific oceans. Their length is up to 15.75 in (40 cm). It has a number of other common names: Australian pilchard, Blue pilchard, Blue-bait, Californian pilchard, Chilean sardine, Japanese pilchard, Pacific sardine, and Southern African pilchard. The South American pilchard is a coastal species that forms large schools. Coloration is blue green on...
