Call it the "Little Bog of Horrors." In what is believed to be a first for North America, biologists at the University of Guelph have discovered that meat-eating pitcher plants in Ontario's Algonquin Park wetlands consume not just bugs but also young salamanders.
Commercial fishers are acutely aware of the potential for marine litter to cause lasting damage to their catches and the wider industry, a new study suggests.
Coral reef experts from around the world are calling for an urgent re-evaluation of our climate goals in the light of increasing evidence of the unprecedented speed of change to these fragile ecosystems. Coral reefs, which have functioned relatively unchanged for some 24 million years, are now going through profound changes in their make-up.
An international team of researchers has analyzed human remains from 21 archaeological sites to learn more about the impact and evolution of the plague-causing bacterium Yersinia pestis during the first plague pandemic (541-750 AD). In a study published in PNAS, the researchers reconstructed 8 plague genomes from Britain, Germany, France, and Spain and uncovered a previously unknown level of diversity in Y. pestis strains. Additionally, they found the first direct genetic evidence of the Justinianic Plague in the British Isles.
New research on the evolutionary relationships between tree sloths and their extinct giant relatives is challenging decades of widely accepted scientific research.
The mineralocorticoid receptor (MR) regulates water and sodium transport throughout cells and tissues, which is critical for controlling blood pressure and so, not surprisingly, the MR is common to all vertebrate animals. Aldosterone, which is a physiological steroid for land vertebrate MRs, evolved in lungfish (forerunners of land vertebrates), suggesting that the evolution of aldosterone was important in the conquest of land by preventing dehydration in animals living out of water.
Fecal transplants from young to aged mice can stimulate the gut microbiome and revive the gut immune system, a study by immunologists at the Babraham Institute, Cambridge, has shown. The research is published in the journal Nature Communications today.
Just like humans leave DNA in the places we inhabit, water-dwelling animals leave DNA behind in the water column. In a paper published June 3 in the journal Current Biology, scientists report that sponges, which can filter 10,000 liters of water daily, catch DNA in their tissues as they filter-feed. This proof-of-concept study identified fish, seal, and penguin DNA in sponges from the Antarctic and Mediterranean, demonstrating that sponges can be used to monitor biodiversity.
An ample buffet of freshwater food, brought on by climate change, is altering the life history of one of the world's most important salmon species.
GAINESVILLE, Fla. --- An ancient, cosmopolitan lineage of plants is shaking up scientists' understanding of how quickly species evolve in temperate ecosystems and why.
New research, led by the University of Bristol, suggests that feathers arose 100 million years before birds - changing how we look at dinosaurs, birds, and pterosaurs, the flying reptiles.
New Guinea is one of the only places in the world where frogs are safe from the species-destroying chytrid fungus. An international team of scientists has published a new paper that shows how to keep it that way, but they need help to carry out their plan.
Biophysicists from the Moscow Institute of Physics and Technology have joined forces with colleagues from France and Germany to create a new fluorescent protein. Besides glowing when irradiated with ultraviolet and blue light, it is exceedingly small and stable under high temperatures.
How did some marine fish manage to make their way from the salty sea to the newly available freshwater niches after the last ice age and eventually differentiate from their marine brethren?
St. Paul, MN (May, 2019)--The chemical compound chloropicrin was first synthesized in 1848 by Scottish chemist John Stenhouse and first applied to agriculture in 1920 when it was used to cure tomato "soil sickness." Over the next decade, it was used to restore pineapple productivity in Hawaii and to address soil fungal problems in California. Over time, it began to be widely used as a fungicide, herbicide, insecticide, and nematicide.
