A new study has mounted perhaps the most intricate, detailed look ever at the diversity in structure and form of bees, offering new insights in a long-standing debate over how complex social behaviors arose in certain branches of bees' evolutionary tree. The report offers strong evidence that complex social behavior developed just once in pollen-carrying bees, rather than twice or more, separately, in different evolutionary branches--but researchers say the case is far from closed.
Underground coal seams engulfed in a fire are not a very pleasant place to live. Nevertheless, Russian scientists, while examining the quarries of the Kemerovo region, showed that microorganisms also live there. They are similar to those that inhabit hot springs and other harsh habitats and are capable of metabolizing carbon monoxide, hydrogen, nitrates, and other compounds that are often hazardous to humans.
Road verges cover 1.2% of land in Great Britain - an area the size of Dorset - and could be managed to help wildlife, new research shows.
The first species-wide survey of parasite infections across the entire range of the mountain gorilla indicates new challenges ahead for the endangered species as its population grows.
The Paleocene-Eocene Thermal Maximum, or PETM, was a short interval of highly elevated global temperatures 56 million years ago that is frequently described as the best ancient analog for present-day climate warming.
Genetic diversity, which reflects the variation in DNA within species and populations and is the key to their capacity to adapt in times of change, is being lost at an alarming rate. According to an article by 28 authors representing 16 countries, the loss of genetic diversity can affect resiliency in the face of environmental change and result in the loss of important services provided to society.
A lot happens and changes within a thin one-meter-thick transition layer between deep Red Sea water and an expansive underlying brine lake.
A new study by University of Liverpool ecologists warns that heat-induced male infertility will see some species succumb to the effects of climate change earlier than thought. Currently, scientists are trying to predict where species will be lost due to climate change so they can plan effective conservation strategies. However, research on temperature tolerance has generally focused on the temperatures that are lethal to organisms, rather than those at which organisms can no longer breed.
The thunder of a mountain river or the crash of pounding surf have likely been changing how animals communicate and where they live for eons. A new experimental study published in the journal Nature Communications finds that birds and bats often avoid habitat swamped with loud whitewater river noise.
Using DNA from greenhouse-grown plants representing all species and hundreds of varieties of watermelon, scientists discovered that watermelons most likely came from wild crop progenitors in northeast Africa. The study corrects a 90-year-old mistake that had previously tied watermelons to South Africa. The genetic research is consistent with newly interpreted Egyptian tomb paintings that suggest the watermelon may have been consumed in the Nile Valley as a dessert more than 4,000 years ago.
