Published Mummified mice discovered atop sky-high Andean volcanoes
(via sciencedaily.com) Original source Scientists have uncovered 13 mummified cadavers of mice from the summits of Andean volcanoes that stretch nearly 4 miles above sea level. Analyses of the mummies, combined with the capture of live specimens, suggest that the mice scaled the Mars-like peaks on their own -- and are somehow managing to live on them.
Published New study shows surprising effects of fire in North America's boreal forests
(via sciencedaily.com) Original source Using satellite images, researchers found that fires in North America's boreal forest may be changing the environment in ways that researchers didn't previously anticipate.
Published Ancient sea monster remains reveal oldest mega-predatory pliosaur
(via sciencedaily.com) Original source The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs.
Published What do new moms and roaches have in common?
(via sciencedaily.com) Original source Researchers are studying the dramatic physical transformation that some insects undergo to give birth to live young. This includes suppressing their immune systems to accommodate babies, which is something some insects and people have in common. Understanding how these systems work can help improve treatments for fibromyalgia and other immune disorders. An international team of researchers has examined the complex structural and physiological changes that take place in Hawaii's beetle-mimic cockroaches, which give birth to live young.
Published Land use: Producing more food and storing more carbon
(via sciencedaily.com) Original source Doubling food production, saving water, and increasing carbon storage capacity -- this may sound paradoxical, but would be theoretically feasible considering the biophysical potential of the Earth. Reaching this goal, however, would require a radical spatial reorganization of land use.
Published Soil carried on sea freight loaded with dangerous pests and diseases, research finds
(via sciencedaily.com) Original source While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.
Published Can golden retrievers live longer?
(via sciencedaily.com) Original source Researchers have found a gene associated with longevity in golden retrievers, one of the most popular breeds of dogs.
Published Unearthing the ecological impacts of cicada emergences on North American forests
(via sciencedaily.com) Original source New research unveils the cascading effects of periodical cicada emergence events on forest ecosystems ahead of an historic convergence of broods set to emerge spring of 2024.
Published Heat waves harm bird reproduction on agricultural lands
(via sciencedaily.com) Original source The effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home. A new study found that extreme high temperatures significantly diminish bird reproductive success in agricultural landscapes.
Published Holy bat skull! Fossil adds vital piece to bat evolution puzzle
(via sciencedaily.com) Original source Bats may have lived in caves and used soundwaves to navigate much earlier than first thought.
Published Scientists discover deepest known evidence of coral reef bleaching
(via sciencedaily.com) Original source Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published Pinpointing the emergence of muddy flavors in your fish
(via sciencedaily.com) Original source Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish.
Published Biodegradable plastics still damaging to fish
(via sciencedaily.com) Original source Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.
Published Drought conditions expose rivers to hotter water temperatures
(via sciencedaily.com) Original source A new study reveals how reduced water flows and rising atmospheric temperatures are set to heat our rivers -- creating major challenges for aquatic life, ecosystems, and society.
Published Study elucidates evolution of mosquitoes and their hosts
(via sciencedaily.com) Original source Study creates a mosquito family tree to better understand disease transmission and host choice.
Published Protecting polar bears: New and improved radar technology
(via sciencedaily.com) Original source Research testing new technology to more effectively locate polar bear dens across the Arctic is showing promising results. Researchers hope that improving detection tools to locate dens -- which are nearly invisible and buried under snow -- will help efforts to protect mother polar bears and their cubs.
Published Reef-devouring predator survives coral bleaching and feasts on the survivors
(via sciencedaily.com) Original source The crown-of-thorns starfish is nature's ultimate coral predator that has a circle of life perfectly adapted to warming waters.
Published Researchers: There is a need for more accurate accounting of nitrous oxide from agricultural crop residues
(via sciencedaily.com) Original source According to researchers, there is a need for changing the way of accounting greenhouse gases from agriculture. The current inventory of nitrous oxide from plant residues relies solely on the amount of nitrogen in the residues, while crucial factors such as the degradability of plant residues are not included. According to the researchers, this leads to misleading inventories, which also misrepresents possible mitigation measures.
Published New mollusk and crustacean species in symbiosis with worms in dead coral rocks
(via sciencedaily.com) Original source The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.
Published Researchers study one of the world's darkest rivers
(via sciencedaily.com) Original source They set out to study the Congo Basin's carbon cycle and in the process have become aware of one of the world's darkest blackwater rivers: the Ruki. In the first study on this major jungle river, an international research team explains how this blackness comes about and what it says about the river system's carbon balance.
