Changing atmospheric conditions may contribute to stronger ocean wave activity on the Antarctic Peninsula

Over the past few years, a large fracture has grown across a large floating ice shelf on the Antarctic Peninsula. The world is watching the ice shelf, now poised to break off an iceberg the size of Delaware into the ocean. It’s not a new phenomenon; this “thumb” of Antarctica, which j

Research shows driving factors behind changes between local and global carbon cycles

Pioneering new research has provided a fascinating new insight in the quest to determine whether temperature or water availability is the most influential factor in determining the success of global, land-based carbon sinks. The research, carried out by an international team of climat

World's biggest tropical carbon sink found in Congo rainforest

A 145,000 sq km area of peatland swamp forest has been discovered in the Congo Basin, writes Tim Radford, and it holds a record 30 Gt of carbon, equivalent to 20 years of US fossil fuel emissions. Now the race is on to protect it from damaging development that would emit that carbon o

Birds of a feather flock together to confuse potential predators

Scientists from the Universities of Bristol and Groningen, in The Netherlands, have created a computer game style experiment which sheds new light on the reasons why starlings flock in massive swirling groups over wintering grounds. A mumeration can hold many thousands of starlings bu

Scientists highlight the critical role of birds in forest regeneration

The loss of birds could significantly impact efforts to combat deforestation, according to research from scientists looking at species across the Brazilian Amazon.  Study results, published in the Journal Philosophical Transactions of the Royal Society B: Biological Sciences show that

Genome sequence of a polar alga explains adaptation to extreme climates

An international team of researchers has identified the genetic mutations which allowed microalgae (phytoplankton) from the Southern Ocean to adapt to extreme and highly variable climates – a step towards understanding how polar organisms are impacted by climate change. The team led b

Changing climate changes soils

The hottest months. The snowiest winters. Catastrophic floods and droughts. Climate change impacts lives across the world in drastic and unpredictable ways. This unpredictability also extends to the more subtle – yet still important – effects of climate change. For example, it is unce

PRESSURE FROM GRAZERS HASTENS ECOSYSTEM COLLAPSE FROM DROUGHT

Extreme droughts, intensified by a warming climate, are increasingly causing ecosystem collapse in many regions worldwide. But models used by scientists to predict the tipping points at which drought stress leads to ecosystem collapse have proven unreliable and too optimistic. A new s

'Shrew'-d advice: Study of Arctic shrews, parasites indicates how climate change may affect ecosystems and communities

MANHATTAN — The shrew and its parasites — even 40-year-old preserved ones — are the new indicators of environmental change, according to a Kansas State University researcher. Andrew Hope, Kansas State University research assistant professor in the Division of Biology, and his colleagu

World's largest tropical peatland discovered in Congo swamps

Avast peatland in the Congo Basin has been mapped for the first time, revealing it to be the largest in the tropics. The new study found that the Cuvette Centrale peatlands in the central Congo Basin, which were unknown to exist five years ago, cover 145,500 square kilometres – an are
