When Mount Pinatubo exploded in 1990, the surrounding Philippine ecosystem was devastated. Scientists thought that the Pinatubo volcano mouse that lived there went extinct. But researchers just discovered the volcano mouse alive and well.
Humans cooperate with each other in large groups to defend territories or wage war. But what underlies the evolution of this kind of cooperation? Researchers at the Max PIanck Institute for Evolutionary Anthropology and Harvard University show that there may be a link between social bonds and participation in large-scale cooperation: Chimpanzees join their close bond partners when fighting rivals. In humans, too, social bonds may have been essential to the evolution of cooperative abilities.
It is now the third year that gray whales have been found in very poor condition or dead in large numbers along the west coast of Mexico, USA and Canada, and scientist have raised their concerns. An international study published this week in the journal Marine Ecology Progress Series, led by Aarhus University researcher Dr Fredrik Christiansen, suggests that starvation is contributing to these mortalities.
New research shows the Ganges River - with the combined flows of the Brahmaputra and Meghna rivers - could be responsible for up to 3 billion microplastic particles entering the Bay of Bengal every day.
By 2050, most people on Earth will live downstream of tens of thousands of large dams built in the 20th century, many of them already operating at or beyond their design life, according to a UN University analysis.
Canine behavioral problems are one of the leading causes of why pets are abandoned at shelters. Researchers have identified some of the key factors in both dogs and their owners that predict the success or failure of clinical interventions to correct problems like aggression or separation anxiety. This information may be valuable for veterinarians to provide better guidance to dog owners in future cases that require clinical intervention.
Marine microalgae-based cellular agriculture is a promising new way to sustainably produce plant-based 'meat' and healthy 'superfoods' for the future. Researchers at Flinders University's Centre for Marine Bioproducts Development (CMBD) in Australia are responding to growing interest from consumers looking for healthier, more environmentally friendly, sustainable and ethical alternatives to animal proteins.
Delivering a minor electric shock into a stream to reveal any fish lurking nearby may be the gold standard for detecting fish populations, but it's not much fun for the trout. Scientists at Oregon State University have found that sampling stream water for evidence of the presence of various species using environmental DNA, known as eDNA, can be more accurate than electrofishing, without disrupting the fish.
A new study from the Institut de Ciències del Mar (ICM-CSIC, Spain) and the National Oceanography Centre brings unprecedented insights into the environmental constraints and climatic events that controlled the formation of the potentially oldest coral reefs in the Mediterranean.
A new study looks to snakes to broaden our understanding of what makes a gene able to survive on a sex-specific chromosome. Comparing surviving genes on snake sex-specific chromosomes to those that are lost to the ravages of time can teach scientists about the evolutionary pressures that shaped sex chromosomes as we know them today.
