Woodlands along streams and rivers are an important part of California's diverse ecology. They are biodiversity hotspots, providing various ecosystem services including carbon sequestration and critical habitat for threatened and endangered species. But our land and water use have significantly impacted these ecosystems, sometimes in unexpected ways.
A long-term passive rewilding study has shown that natural woodland regeneration could make a significant contribution to meeting the UK's ambitious tree planting targets - potentially at no cost and within relatively short timescales. The research, led by the UK Centre for Ecology & Hydrology (UKCEH), found natural growth due to seed dispersal by birds, mammals and wind can produce biodiverse and resilient woodland.
The German National Academy of Sciences Leopoldina and the German Council for Sustainable Development (RNE) have published a joint position paper presenting paths to climate neutrality by 2050. In it, the Leopoldina and the RNE highlight options for action to effect the changes needed within society, at political level and in the business world, in view especially of the urgency and the historic dimensions of the transformation we face.
Weddell seals, the southernmost born mammal, are known as champion divers. But they don't begin life that way. Cal Poly researchers examined the development of diving behavior in Weddell seal pups and found that they time their dives with their mother but likely do not learn to forage at that time. Instead, they focus their early efforts on learning to swim and navigate under the sea ice.
When animals are hot, they eat less. This potentially fatal phenomenon has been largely overlooked in wild animals, explain researchers from The Australian National University (ANU).
Conservationists have long warned of the dangers associated with bears becoming habituated to life in urban areas. Yet, it appears the message hasn't gotten through to everyone. News reports continue to cover seemingly similar situations -- a foraging bear enters a neighbourhood, easily finds high-value food and refuses to leave. The story often ends with conservation officers being forced to euthanize the animal for public safety purposes.
SUTD-led research has demonstrated a technology that allows users with camera phones to track the health of aquatic microorganisms -- assessing water quality and drinkability in the process.
An algorithm can predict when narwhals hunt - a task once nearly impossible to gain insight into. Mathematicians and computer scientists at the University of Copenhagen, together with marine biologists in Greenland, have made progress in gathering knowledge about this enigmatic Arctic whale at a time when climate change is pressuring them.
Some of the world's most vulnerable cities suffer disproportionate economic losses because of the health consequences of in-car air pollution, finds a new study.
Many countries are already looking to adopt clean heating solutions more widely, with the International Energy Agency projecting that by 2045 nearly half of global heating will be done with heat pumps. A new study from Aalto University assesses the impact of heat pumps on energy consumption as well as how they should be subsidized.
