Study Revises Theory on Growth and Carbon Storage in Mature Trees
Woods Hole MA (SPX) Jun 04, 2014 -
As forests age, their ability to grow decreases, a new study by Marine Biological Laboratory (MBL) scientists and colleagues has determined. Since most U.S. forests are maturing from regeneration that began about 100 years ago when extensive clear-cutting occurred, the study suggests the future growth of U.S. forests will decline.
"All forests are in succession: They get old, die (due to f ...

Parasites fail to halt European bumblebee invasion of the UK
London, UK (SPX) Jun 04, 2014 -
A species of bee from Europe that has stronger resistance to parasite infections than native bumblebees has spread across the UK, according to new research at Royal Holloway, University of London.
The study, published in the Journal of Animal Ecology, shows that tree bumblebees have rapidly spread despite them carrying high levels of an infection that normally prevents queen bees from prod ...

Feeding increases coral transplant survival
London, UK (SPX) Jun 05, 2014 -
Feeding juvenile corals prior to transplantation into a new reef may increase their survival, according to a study published June 4, 2014 in the open-access journal PLOS ONE by Tai Chong Toh from the National University of Singapore and colleagues.
The global decline of coral reefs and the loss of associated ecological services have necessitated immediate intervention measures to try to re ...

Prototype electrolyte sensor to provide immediate read-outs
Albuquerque NM (SPX) Jun 04, 2014 -
Patients trying to navigate today's complex medical system with its costly laboratory analyses might prefer a pain-free home diagnostic device, worn on the wrist, that can analyze, continuously record and immediately remedy low electrolyte levels.
Runners, athletes in other strenuous sports and soldiers on long missions also might prefer immediate knowledge of their electrolytic states as ...

Cleaning the Air with Roof Tiles
Riverside CA (SPX) Jun 05, 2014 -
A team of University of California, Riverside's Bourns College of Engineering students created a roof tile coating that when applied to an average-sized residential roof breaks down the same amount of smog-causing nitrogen oxides per year as a car driven 11,000 miles.
They calculated 21 tons of nitrogen oxides would be eliminated daily if tiles on one million roofs were coated with their t ...

Iron, steel in hatcheries may distort magnetic 'map sense' of steelhead
Corvallis OR (SPX) Jun 04, 2014 -
Exposure to iron pipes and steel rebar, such as the materials found in most hatcheries, affects the navigation ability of young steelhead trout by altering the important magnetic "map sense" they need for migration, according to new research from Oregon State University.
The exposure to iron and steel distorts the magnetic field around the fish, affecting their ability to navigate, said Na ...
