While invasive zebra mussels consume small plant-like organisms called phytoplankton, Michigan State University researchers discovered during a long-term study that zebra mussels can actually increase Microcystis, a type of phytoplankton known as “blue-green algae” or cyanobacteria, that forms harmful floating blooms.
A new study by IIASA researchers, Russian experts, and other international colleagues have produced new estimates of biomass contained in Russian forests, confirming a substantial increase over the last few decades.
Specific health effects of toxins on the water surface of the Indian River Lagoon are not fully understood. Scientists collected water samples during the 2018 wet and 2019 dry seasons and analyzed them. Results showed that concentrations of Microcystis aeruginosa, harmful algal blooms, and saxitoxin, a neurotoxin, were both generally higher during the wet season. Microcystins, produced by blue-green algae, were present only under specific environmental conditions.
As summer unfolds, more than 500 species of invasive plants will be taking root in fields, lawns, and gardens across the US. As plants continue to move north driven by climate change, the number of invasives will only increase.
Communication is crucial for elephants that live in complex multi-tiered social systems. Apart from their iconic trumpets uttered through the trunk, Asian elephants also produce species-specific squeaks by buzzing their lips. This demonstrates once again the elephant’s flexibility in sound production.
A team of researchers from the University of Pittsburgh, University of Minnesota, and U.S. Geological Survey have developed a new machine learning technique that could improve environmental predictions.
Leaf-cutter ants tend fungal gardens that convert lipids in leaves into lipids the ants can use for energy, building cells, and communication between organisms. New research has found that different regions of the ants’ fungal gardens were enriched with different lipids. This helps scientists understand communications between organisms in different kingdoms of life.
As well as bright colours and subtle scents, flowers possess many invisible ways of attracting their pollinators, and a new study shows that bumblebees may use the humidity of a flower to tell them about the presence of nectar, according to scientists at the Universities of Bristol and Exeter.
Researchers from the National University of Singapore and University of the Ryukyus have recently identified and described a new genus and species of xanthid crab found in Okinawa Island, Ryukyu Islands, Japan. Named Mabui calculus, it is the first among the 7,800 species of known crabs to have strongly asymmetrical male and female reproductive structures.
A study conducted in the Una Biological Reserve in the state of Bahia, Brazil, shows that in a habitat with high hunting pressure the risk of predation has such a significant impact on the behavior of the Yellow-breasted capuchin monkey Sapajus xanthosternos that it even avoids areas offering an abundant supply of plant biomass and invertebrates, its main sources of food.
Irvine, Calif., June 21, 2021 – A shift is happening in Southern California, and this time it has nothing to do with earthquakes. According to a new study by scientists at the University of California, Irvine, climate change is altering the number of plants populating the region’s deserts and mountains. Using data from the Landsat satellite mission and focusing on an area of nearly 5,000 square miles surrounding Anza-Borrego Desert State Park, the research team found that between 1984 and 2017, vegetation cover in desert ecosystems decreased overall by about 35 percent, with mountains seeing a 13 percent vegetation decline.
In Japan, thousands of homes and businesses and hundreds of lives have been lost to typhoons. But now, researchers have revealed that a new flood forecasting system could provide earlier flood warnings, giving people more time to prepare or evacuate, and potentially saving lives.
Climate change will shape the future of coastal communities, with flood walls, elevated structures and possibly floating cities used to combat sea level rise. New research has found that managed retreat must be part of the solution now, and not a last resort.
Like the movie version of Spider-Man who shoots spider webs from holes in his wrists, a little alpine plant has been found to eject cobweb-like threads from tiny holes in specialised cells on its leaves.
A new article, published as a Perspective in the journal Conservation Science and Practice, introduces a rapid assessment framework that can be used as a guide to make conservation and nature-based solutions more robust to future climate.
Using a numerical model that simulates ocean currents, researchers are shedding light on the important “motion of the ocean” in the Straits of Florida. They have conducted a first-of-its-kind study identifying the mechanisms behind the formation of sub-mesoscale eddies, which have important environmental implications and play a significant role in the health of the Florida Keys coral reef ecosystem.
IIASA, the Food and Agriculture Organization of the United Nations (FAO), and the Environmental System Research Institute (ESRI) are proud to announce the launch of version 4 of the Global Agro-Ecological Zones platform (GAEZ v4) to support sustainable development in the agricultural sector.
Last fall, the Mullen fire west of Laramie raged for the better part of two months, burning more than 176,000 acres and 70 structures in Wyoming's Carbon and Albany counties, and in Jackson County, Colo.
The original Star Trek television series took place in a future when space is the final frontier, but humanity hasn’t reached that point quite yet. As researchers like Michigan State University entomologists Sarah Smith and Anthony Cognato are reminding us, there’s still plenty to discover right here on Earth.
Working in Central and South America, the duo discovered more than three dozen species of ambrosia beetles — beetles that eat ambrosia fungus — previously unknown to science. Smith and Cognato described these new species on June 16 in the journal ZooKeys.
A Penn State-led team of researchers report they have taken a step toward overcoming the challenge of inexpensive hydrogen production by using supercomputers to find materials that could help accelerate hydrogen separation when water is exposed to light, a process called photocatalysis.
A new study from University of Utah researchers suggests that, due to deforestation and habitat degradation, more bird species may be endangered that previously thought – including species that may not have been discovered yet.
Woods Hole, MA (June 16,2021) -- Woods Hole Oceanographic Institution (WHOI) climate modeler Dr. Alan Condron and United States Geological Survey (USGS) research geologist Dr. Jenna Hill have found evidence that massive icebergs from roughly 31,000 years ago drifted more than 5000km (> 3,000 miles) along the eastern United States coast from Northeast Canada all the way to southern Florida. These findings were published today in Nature Communications.
Researchers reporting in ACS’ Environmental Science & Technology have analyzed more than 25 years of Antarctic data, finding that ozone concentrations near the ground arose from both natural and human-related sources.
Researchers reporting in Environmental Science & Technology have analyzed antibiotic-resistance genes (ARGs) on five types of microplastics at different locations along the Beilun River in China, finding much higher abundances in urban than rural regions.
Peatlands, which make up 3 percent of Earth’s total land area, are known by a number of names — moors, mires, bogs, swamps and portions of permafrost tundra. They also store a significant amount of the Earth’s carbon. A research team from Florida State University and Georgia Institute of Technology are paying close attention to these complicated systems because they’ve found that the warming Earth is stimulating complex ecosystem changes with the end result of even more greenhouse gases being released into the air.
A study of woodland ecosystems that provide habitat for rare and endangered species along streams and rivers throughout California reveals that some of these ecologically important areas are inadvertently benefitting from water that humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended dependence on its bounty, threatens the long-term survival of natural communities and spotlights the need for changes in the way water is managed across the state.
The free online series of short videos are designed to provide basic, jargon-free scientific information on harmful algal blooms: what they are; where they live and grow; and causes, impacts, and potential mitigation of blooms. The series is directed toward resource managers and decision-makers as well as the general public.
While best known as the code for genetic information, DNA is also a nutrient for specialised microbes. An international team of researchers led by Kenneth Wasmund and Alexander Loy from the University of Vienna has discovered several bacteria in sediment samples from the Atlantic Ocean that use DNA as a food source.
Carbon footprint declarations are used in construction to ease product selection for low carbon building, but these standards don’t yet exist for green elements like soil, bushes and plants. A new study led by Aalto University is the first to map out how green infrastructure can be a resource for cities on the path to carbon neutrality.
Endangered blue whales are present and singing off the southwest coast of India. The results provide insight into a poorly studied population and suggest conservation measures should include this region.
Researchers from Tel Aviv University took part in a new international study proposing an amendment to the widely accepted theory on the extinction of animal species - by moving the focus from the animal's body size to its reproductive capacity.
Lack of water, floods, or crop losses: As a result of climate change, pronounced periods of drought and rainfall are occurring more frequently and more intensively all around the world, causing human suffering and major economic damage.
PNNL’s Framework for Assessment of Complex Environmental Tradeoffs (FACET) is designed to navigate and rigorously evaluate competing environmental, economic, and social impacts to help make decisions more equitable. In an example scenario prepared using publicly available data, FACET was applied to predict tradeoffs facing the Colorado River and to balance competing demands of river flow and temperature, along with withdrawals for cities, crop irrigation, and power generation.
