Contaminants also a threat to polar bears
The polar bear (Ursus maritimus), one of the largest carnivorous mammals on Earth, is vulnerable to a series of dangers. An international team has established a guide to evaluate the condition of its health, ...
Hidden costs: The unseen way organisms cope with climate change
Scientists have found a way to measure the unseen toll that environmental stress places on living creatures—showing that they can rev up their metabolism to work more than twice as hard as normal to cope ...
Environmental 'tipping points' key to predicting extinctions
Researchers from North Carolina State University have created a model that mimics how differently adapted populations may respond to rapid climate change. Their findings demonstrate that depending on a population's ...
Cane toad pioneers speed up invasions
Looking to space to quantify natural gas leaks on Earth
The recent increase in natural gas production could provide a bridge to a lower carbon future because it generates half the carbon dioxide (CO2) of coal when burned. However, natural gas that is leaked into ...
Ocean pipes 'not cool,' would end up warming climate
To combat global climate change caused by greenhouse gases, alternative energy sources and other types of environmental recourse actions are needed. There are a variety of proposals that involve using vertical ...
Severe changes in world's leaf growth patterns over past several decades revealed
Extensive worldwide changes in the timing of leaf activity over the past few decades—which may have significant ecological and atmospheric consequences—have been revealed by a University of Otago, New ...
Tiny fish provides giant insight into how organisms adapt to changing environment
An Indiana University-Dartmouth College team has identified genes and regulatory patterns that allow some organisms to alter their body form in response to environmental change.
Changing global diets is vital to reducing climate change
A new study, published today in Nature Climate Change, suggests that – if current trends continue – food production alone will reach, if not exceed, the global targets for total greenhouse gas (GHG) emissi ...
Are flexible parents adaptable parents?
(Phys.org) —The flexibility of parental behaviours to respond to changes in behaviour of their offspring may actually constrain the ability of parents to adapt to changes in their wider environment.
Epoch-defining study pinpoints when humans came to dominate planet Earth
The human-dominated geological epoch known as the Anthropocene probably began around the year 1610, with an unusual drop in atmospheric carbon dioxide and the irreversible exchange of species between the ...
Dire outlook despite global warming 'pause': study
A global warming "pause" over the past decade may invalidate the harshest climate change predictions for the next 50 to 100 years, a study said Sunday—though levels remain in the danger zone.
Disappearing lakes stoke megafauna debate
New research into central Australia's ancient lakes has found evidence that climate change contributed to the extinction of the continent's megafauna.
Hormone disrupting chemicals and climate change increase risk of extinction in wildlife
The impact of pollution on wildlife could be made dramatically worse by climate change according to a new study published today in the journal PNAS.
