Loss of habitat and human activities such as fishing and shipping pose a grave threat to wildlife but diseases driven by the smallest organisms in the ocean are a less understood side of marine conservation.
Coral reefs in one part of the Pacific Ocean have likely adjusted to higher ocean temperatures which could reduce future bleaching impacts of climate change, new research reveals.
The entire contiguous U.S. has experienced massive urban expansions and the Atlantic Coast shows outstandingly high rates. Urban expansion has substantially squeezed the space of tidal flats and affected surrounding environments. In new urban areas, tidal flats have undergone considerable degeneration with more significant patterns as they get closer to new urban locations. Tidal flats protect against the ocean’s destructive powers such as hurricanes. Without some inland spaces to move around, they will likely disappear, which will have dire consequences for beachfront communities.
Freshwater is vital for humans, ecosystems, and economies. However, climate and socio-economic changes are expected to substantially alter water availability. A pioneering study emphasizes considering future water withdrawals in low flow projections, highlighting the urgency of coordinated efforts to reduce excessive extraction in European rivers.
The discovery that birds evolved from small carnivorous dinosaurs of the Late Jurassic was made possible by recently discovered fossils of theropods such as Tyrannosaurus rex and the smaller velociraptors. In a way, you could say that dinosaurs are still with us and seen tweeting from your own backyard! Below are the latest research headlines in the Birds channel on Newswise.
Associate Professor Yoshi N. Sasaki, a specialist in Physical Oceanography, is involved in research into rising sea levels—particularly in coastal areas of Japan. He spoke about what he has learned so far about the relationship between ocean currents, sea level and climate change, what research he is currently focusing on, and the appeal of research that uses numerical modeling to uncover natural phenomena.
An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind.

Russian limnologists have investigated the chemical composition of a small reservoir in the north-western part of Russia and have found out that sediment cores (slits) meet the standards of heavy metals concentrations. The scientist have established that the lake is clean despite the close proximity of a railway and a village. Theoretically, the lake’s sediment cores may be used in agricultural work or medicine.
Scientists analyzed the condition of ecosystems of high latitude lakes and found out that increasing of water temperature leads to increasing of population, rapid growth and early maturation of perches. It points to the fact that in future thermophilic fish like perch can force out cold-water salmon species.
New research shows that the hormone testosterone — which naturally triggers male electric fish to elongate the electric pulses they send out during the breeding season — also alters a system in the fish’s brain that enables the fish to ignore its own electric signals.
A study of 12 species of highly migratory fish predators—including sharks, tuna, and billfish such as marlin and swordfish—finds that most of them will encounter widespread losses of suitable habitat and redistribution from current habitats in the Northwest Atlantic Ocean (NWA) and the Gulf of Mexico (GOM) by 2100. These areas are among the fastest warming ocean regions and are projected to increase between 1-6°C (+1-10°F) by the end of the century, a sign of climate-driven changes in marine ecosystems.
When predicting the future, some people use a crystal ball or tarot cards. When Missouri University of Science and Technology geologist Dr. Jonathan Obrist-Farner does it, he uses sediment core samples.
Safe drinking water is threatened globally by the increased toxicity of phytoplankton — or microscopic algae — blooms. The need for a better understanding of when and where the blooms will emerge spurred Virginia Tech researchers to start developing the first automated, real-time lake phytoplankton forecasting system. Working with the University of Florida, Virginia Tech faculty have been awarded a $2.
In the search for ways to fight methylmercury pollution in global waterways, scientists at Oak Ridge National Laboratory discovered that some forms of phytoplankton are good at degrading the substance.
Groupers produce distinct sounds associated with courtship, territoriality or reproduction. An autonomous mobile wave glider and passive acoustics were deployed to survey two marine protected areas on the western shelf of Puerto-Rico to locate spawning aggregations of two commercially important species – the Nassau and red hind groupers. Findings show these sites are critical habitat for both species and multiple previously unknown grouper species, which highlight the importance of expanding existing seasonal regulations.
Oak Ridge National Laboratory (ORNL), the Department of Energy’s largest multidisciplinary laboratory, and Fairbanks Morse Defense (FMD), a portfolio company of Arcline Investment Management, have entered into a Memorandum of Understanding (MOU) to collaborate on the development and integration of alternative fuel technologies aimed at reducing the marine engine’s reliance on fossil fuels.

The experimental results shed light on the molecular basis of how formulated diets affect muscle characters, and lay the ground-work for future nutritional regulation and genetic improvements in the meat quality of largemouth bass.
The red swamp crayfish—found originally in tropical regions—has become a highly invasive species across the globe. Over the years, they have successfully colonized habitats much colder than their original habitats, but the factors determining their cold resistance have remained elusive. Recently, a group of researchers in Japan has discovered genes that may help the red swamp crayfish produce protective proteins and adapt to the cold.
With mighty jaws and plate-like teeth, the globally endangered whitespotted eagle ray can pretty much crunch on anything. Yet, little information is available on critical components of their life history in the U.S., such as their diet.
The pygmy right whale is an enigma in the whale world. Not only is it the smallest of the characteristically large filter-feeding baleen whales, but it’s also rarely sighted and seldom studied – partly because of its inconspicuous nature and resemblance to minke whales.
Resilient corals, often referred to as ‘super corals’, have recently been seen as potential saviours in the face of climate change and its detrimental effects on coral reefs. Now, a team of scientists is working to better understand these corals in order to develop strategies to protect fragile ecosystems such as the Great Barrier Reef.
University of Miami Rosenstiel School researchers Daniel Suman and Claire B. Paris-Limouzy are co-authors of a recent journal article that outlines ways to achieve greater equity in ocean governance and science in the global tropics. And one of those ways is by allowing residents to have a say in policy making.
