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
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.
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.
Chemists observe key reaction for producing 'atmosphere's detergent'
Earth's atmosphere is a complicated dance of molecules. The chemical output of plants, animals and human industry rise into the air and pair off in sequences of chemical reactions. Such processes help maintain ...
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.
Genetic study shows major impact of climate change on Antarctic fur seals
Genetic analysis of Antarctic fur seals, alongside decades of in-depth monitoring, has provided unique insights into the effect of climate change on a population of top-predators. Published in Nature this week, the findin ...
Should we listen to our genes, or does mother know best?
Breaking the mould of inherited family characteristics could help you survive in a fast-changing world, scientists have discovered.
Environmental change leaves its footprint in the epigenome
(Phys.org) —Monozygotic twins look more similar when they are young than later in life. One of the reasons for this is epigenetic change in the form of chemical modifications of the DNA or its packaging ...
How does snow affect the amount of water in rivers?
New research has shown for the first time that the amount of water flowing through rivers in snow-affected regions depends significantly on how much of the precipitation falls as snowfall. This means in a ...
Future heat waves pose threat to global food supply, study says
Heat waves could significantly reduce crop yields and threaten global food supply if climate change is not tackled and reversed.
The water cycle amplifies abrupt climate change
During the abrupt cooling at the onset of the so-called Younger Dryas period 12680 years ago changes in the water cycle were the main drivers of widespread environmental change in western Europe. Thus, the ...
Team finds receptors that help plants manage environmental change, pests and wounds
ATP (adenosine triphosphate) is the main energy source inside a cell and is considered to be the high energy molecule that drives all life processes in animals and humans. Outside the cell, membrane receptors ...
