Fish diversity documented in Switzerland"s rivers
In a major survey of Swiss rivers and streams, more than 50 different fish species were recorded. For the first time, more than one species was also found in the case of smaller types of fish such as the bullhead. In Progetto Fiumi, riverine fish wer.....»»
Off Ecuador"s Galapagos, a former shark-poaching ship"s new mission
When Ecuador's navy seized a Chinese-flagged ship off the Galapagos Islands in 2017, its hold brimmed with tons and tons of poached fish, many of them threatened species like hammerhead and thresher sharks......»»
Team develops a technique to detect nutrients in soil faster and more affordably
Every year, Missouri farmers lose millions of dollars in valuable nutrients that wash away into rivers and lakes. These nutrients—nitrates and phosphates found in fertilizers—are crucial for plant growth, but they wreak havoc on aquatic life when.....»»
Ciliated eukaryotes study offers simple, versatile method for tubulin staining
Ciliates, a group of single-celled ciliated eukaryotes, have been studied since the dawn of light microscopy, with over 10,000 species described. Cilia are the key feature of ciliates and contribute to their diversity. They vary in length, covering t.....»»
Mexico tries to bring drought-stricken lake back to life
Mexican authorities are releasing thousands of juvenile fish and cleaning up freshwater springs as part of efforts to rejuvenate one of the country's lakes stricken by drought and heat waves......»»
Using AI to scrutinize and validate theories on animal evolution
By harnessing the power of machine learning, researchers have constructed a framework for analyzing what factors most significantly contribute to a species' genetic diversity......»»
Baby bull sharks are thriving in Texas and Alabama bays as the Gulf of Mexico warms
In late spring, estuaries along the U.S. Gulf Coast come alive with newborn fish and other sea life. While some species have struggled to adjust to the region's rising water temperatures in recent years, one is thriving: juvenile bull sharks......»»
Fish biodiversity found to benefit nutrition, particularly for lower income people
Households caught and consumed a far more diverse array of fish than they sold at market, which has important implications for how loss of biodiversity might affect people's nutrition, especially for those with lower incomes. A Cornell study is one o.....»»
Fish barriers may aid baby corals in reef recovery
Scientists from the Australian Institute of Marine Science (AIMS) and James Cook University (JCU) have designed special cradles for baby corals that help prevent fish from eating them alive......»»
The most endangered fish are the least studied, scientists find
The most threatened reef fish are also the most overlooked by scientists and the general public. That is the startling finding of a team of scientists led by a CNRS researcher......»»
Scientists identify brain circuits tied to the behavior of schooling fish
A flock of migrating geese glides through the summer sky in an unmistakable "V" formation… a thundering herd of bison rumbles across the plains as a formidable group... and a massive school of sardines swims mesmerizingly in unison......»»
New research sheds light on river dynamics and cutoff regimes
How are rivers characterized? Traditional methods rely on plant forms and sedimentological techniques, focusing on deposits. Riccardo Maitan, a Ph.D. candidate at the University of Padova, is developing a novel approach based on river hydrological be.....»»
Research tracks 66 million years of mammalian diversity
When trying to understand the present, it's helpful to look to history. New research from the University of Nebraska–Lincoln examined the fossil record going back 66 million years and tracked changes to mammalian ecosystems and species diversity on.....»»
Freezing and melting reshape diversity and structure of glacier microbial communities
With the increasing attention on global climate change and glacier retreat, the study of glacier microbiota has gradually become an important field of research......»»
Study detects the largest methane leak ever recorded in an oil well
An international team of scientists led by Dr. Luis Guanter, UPV professor and head of the LARS Group of the Institute of Water and Environmental Engineering of the Universitat Politècnica de València (IIAMA-UPV), has documented the largest methane.....»»
Scientists use machine learning to predict diversity of tree species in forests
A collaborative team of researchers led by Ben Weinstein of the University of Florida, Oregon, US, used machine learning to generate highly detailed maps of over 100 million individual trees from 24 sites across the U.S., and published their findings.....»»
After grizzly"s death, environmental groups to sue Fish and Game over Idaho bear baiting
Several environmental activist groups on July 15 notified state officials and the Idaho Department of Fish and Game that they intend to file a lawsuit over the agency's allowance of bear baiting, which the groups said put federally protected grizzly.....»»
Loneliness in the workplace is greatest among men with traditional views about being the breadwinner
Loneliness affects everyone at different times. Although it is well documented men are less likely than women to talk about feelings and to seek help, our research found men's work arrangements can be a significant contributor......»»
Asexual reproduction usually leads to a lack of genetic diversity. Not for these ants
Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, forming a genomically robust offspring with two disti.....»»
Along shifting coastlines, scientists bring the future into focus
In the wet, muddy places where America's rivers and lands meet the sea, scientists from the Department of Energy's Oak Ridge National Laboratory are unearthing clues to better understand how these vital landscapes are evolving under climate change......»»
Much of Neanderthal genetic diversity came from modern humans
Neanderthals' low diversity means their population was even smaller than we thought. Enlarge (credit: Halamka) The basic outline of the interactions between modern humans and Neanderthals is now well established. The two.....»»
