Warming lakes and rivers may spread fish pathogens
Michigan's rivers and lakes were once cold enough that fish were protected from some infection-causing parasites. As the Great Lakes ecosystem warms, a Michigan State University researcher is investigating new pathogens that may become relevant to th.....»»

Biologists discover a new fossil species of prehistoric fish
What do the ginkgo (a tree), the nautilus (a mollusk) and the coelacanth (a fish) all have in common?.....»»
When ribosomes go rogue
Unusual variations in the cellular protein factory can skew development, help cancer spread, and more. But ribosome variety may also play biological roles, scientists say. In the.....»»
River flow responses to heat waves may change more rapidly under climate change, research finds
A pair of studies by researchers in Simon Fraser University's School of Environmental Science examine how climate change could alter the way Canadian rivers respond to extreme heat events......»»
"Paleo-robots" provide an experimental approach for understanding how fish started to walk on land
The transition from water to land is one of the most significant events in the history of life on Earth. Now, a team of roboticists, paleontologists and biologists is using robots to study how the ancestors of modern land animals transitioned from sw.....»»
Polar bears" exposure to pathogens is increasing as their environment changes, blood samples suggest
As the Arctic warms, polar bears now face a greater risk of contracting several pathogens than bears three decades ago. Karyn Rode and Caroline Van Hemert of the U.S. Geological Survey report these findings in a new study published October 23, 2024,.....»»
Insect and spider biodiversity increases organic nutrient availability across ecosystems, large-scale study shows
Insects and spiders are important elements in the food webs of aquatic and terrestrial ecosystems. With declines in their biodiversity, the food supply for birds, fish, reptiles, amphibians and small mammals is not only becoming scarcer, but also poo.....»»
Future atmospheric rivers could bring catastrophic ocean level rise off the West Coast, simulation study shows
A team of climate specialists from the NSF National Center for Atmospheric Research, Climate and Global Dynamics Lab, Texas A&M University, and Pennsylvania State University has found evidence for a rise in ocean levels during future atmospheric rive.....»»
Ethical framework aims to counter risks of geoengineering research
As interest grows in geoengineering as a strategy for tackling global warming, the world's largest association of Earth and space scientists has launched an ethical framework as a guide to responsible decision-making and inclusive dialogue......»»
Researcher finds special proteins are key when antibiotic resistance spreads
Antibiotic resistance is a growing public health problem globally. The problem is exacerbated by the fact that some bacteria that have become resistant to antibiotics have the ability to spread that resistance to other bacteria via secretion systems......»»
Polar bears are sustaining ice-related paw injuries in a warming Arctic
Polar bears in some parts of the high Arctic are developing ice buildup and related injuries to their feet, apparently due to changing sea ice conditions in a warming Arctic. While surveying the health of two polar bear populations, researchers found.....»»
Giant fish thought to be extinct is spotted in the Mekong River
A huge fish in the Mekong River thought to be extinct has been spotted three times in recent years......»»
Study suggests frogs and toads will face new risks as water habitats dry up due to global warming
A small international team has found that anurans such as frogs and toads will be facing increased risks to their survival in the coming years due to water habitats drying up as a result of global warming......»»
To truly understand the health of a lake, you must look well beyond its shoreline
On the surface, most of Canada's lakes and rivers look pristine. But below the surface, many are facing essential challenges to their health. Why? To better understand the health of Canadian lakes and rivers, we must look beyond the site itself to th.....»»
Climate change to alter seasonal outdoor activity patterns in US
It can be hard to connect a certain amount of average global warming with one's everyday experience, so researchers at MIT have devised a different approach to quantifying the direct impact of climate change......»»
Attribution studies reveal increasing effects of global warming on fire dynamics and public health
Climate change is increasingly influencing fire behavior worldwide and intensifying fire smoke, endangering public health from air pollution caused by fires. These are the results of two new climate change impact attribution studies, both published i.....»»
"Nano-weapon" discovery boosts fight against antibiotic-resistant hospital superbugs
Researchers have discovered how a bacteria found in hospitals uses "nano-weapons" to enable their spread, unlocking new clues in the fight against antibiotic-resistant superbugs......»»
Invasive flathead catfish impacting Susquehanna"s food chain, researchers find
Flathead catfish—native to the Mississippi River basin—were first detected in the Susquehanna River in Pennsylvania in 2002, according to the U.S. Geological Survey. In the two decades since then, the invasive species has spread throughout the ri.....»»
Bizarre fish has sensory “legs” it uses for walking and tasting
Some sea robin species can use their legs to sense prey. Evolution has turned out bizarre and baffling creatures, such as walking fish. It only gets weirder from there. Some of th.....»»
Q&A: Experts discuss the beaver, a controversial mammal
When an endangered species succeeds in repopulating its former habitat, the immediate reaction is one of joy. In the long term, however, its spread is often associated with conflict. One example is the beaver, a keystone species. Other keystone speci.....»»
