Cane toad pioneers speed up invasions
Evidence contradicts idea that starvation caused saber-tooth cat extinction
The latest study of the microscopic wear patterns on the teeth of the American lions and saber-toothed cats that roamed North America in the late Pleistocene found that they were living well off the fat of ...
Fluctuating environment may have driven human evolution
A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University.
Curiosity providing new weather and radiation data about Mars
(Phys.org)—Observations of wind patterns and natural radiation patterns on Mars by NASA's Curiosity rover are helping scientists better understand the environment on the Red Planet's surface.
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 ...
Light variation drives community structure of a hypersaline microbial mat
When scientists at Pacific Northwest National Laboratory took samples of a microbial mat community from a hypersaline lake to study community responses to environmental changes, they expected to find that ...
How bacteria respond so quickly to external changes
Understanding how bacteria adapt so quickly to changes in their external environment with continued high growth rates is one of the major research challenges in molecular microbiology. This is important not least for our ...
