Researchers have found warmer average water temperatures in Ontario lakes over the past decade have forced fish to forage in deeper water.
Striking colors that are seen only in the males of some species are partly explained by gene behavior, research into guppy fish suggests.
The self-reported struggle of many countries to design effective plans to achieve the UN's Sustainable Development Goals has inspired a new UN tool to guide such nations along a 6-step path towards the critical SDG 6: clean water and sanitation for all. The SDG Policy Support System launches March 22, World Water Day, on the website of UNU-INWEH. It draws on extensive research into a universal recipe for accelerating SDG-6 progress.
The first survey of methane vent sites off Washington's coast finds 1,778 bubble columns, with most located along a north-south band that is in line with a geologic fault.
When you flush the toilet, you probably don't think about the traces of the medicine and personal care products in your body that are winding up in sewage treatment plants, streams, rivers, lakes, bays and the ocean. But Rutgers scientists have found that bacteria in sewage treatment plants may be creating new contaminants that have not been evaluated for potential risks and may affect aquatic environments, according to a study in Environmental Toxicology and Chemistry.
Female birds age more slowly and live longer when they have help raising their offspring, according to new research from the University of Sheffield.
Research shows that females age more slowly and live longer when they have help raising their offspring. Researchers studied the relationship between ageing and offspring rearing patterns in the Seychelles warbler, and found that females who had assistance from other female helpers benefitted from a longer, healthier lifespan. The findings help explain why social species, such as humans, which live in groups and cooperate to raise offspring, often have longer lifespans.
When consumed in contaminated water, the microscopic parasite Cryptosporidium can cause symptoms of stomach cramps, diarrhea and fever. Now, researchers reporting in the ACS journal Environmental Science & Technology have detected evidence of the parasite in about 40 percent of surveyed wells in public water systems in Minnesota -- even wells not influenced by surface water. The team emphasizes that they don't know whether the parasite levels are high enough to actually cause health concerns.
Urogenital schistosomiasis (US), a chronic parasitic disease, is endemic in Ghana and policymakers have undertaken efforts to control it, largely through mass drug administration of praziquantel given to school-aged children. Now, researchers reporting in PLOS Neglected Tropical Diseases have found that awareness of Female Genital Schistosomiasis (FGS), a specific gender manifestation of US, is lacking, which affects the ability to control this disease in girls and women.
The dramatic difference in gonad size between honey bee queens and their female workers in response to their distinct diets requires the switching on of a specific genetic program, according to a new study publishing March 21 in open-access journal PLOS Biology by Annika Roth and Martin Beye of Heinrich-Heine University in Dusseldorf and colleagues. The finding may aid analysis of the interplay of genes and nutrition that drive caste dimorphism in honey bees.
