Marine ecologists have revealed mangroves might be threatened by a limited number of crustaceans, molluscs and other invertebrates for each ecological role.
In September 2017, Woods Hole Oceanographic Institution postdoctoral scholar Maggie Johnson was conducting an experiment with a colleague in Bocas del Toro off the Caribbean coast of Panama. After sitting on a quiet, warm open ocean, they snorkeled down to find a peculiar layer of murky, foul-smelling water about 10 feet below the surface, with brittle stars and sea urchins, which are usually in hiding, perching on the tops of coral.
Stepping into the gap between the rocks, it's easy to understand what Brian Helmuth is talking about.
An international team of researchers from the Max Planck Institute for Plant Breeding Research and the University of Aarhus in Denmark have discovered that bacteria from the plant microbiota are adapted to their host species. In a newly published study, they show how root-associated bacteria have a competitive advantage when colonizing their native host, which allows them to invade an already established microbiota.
Citrus fruits from the mandarin family are popular throughout the world for their tasty and healthy characteristics. Within Japan, the tiny shiikuwasha and the ornamental tachibana are of special cultural and historical importance. However, the origin of these two varieties, and other East Asian citrus, was something of a mystery until now.
Breakthrough experiments conducted at ASC's deep submarine maintenance facility in Adelaide have demonstrated how electrically charged surface coatings can eliminate marine bio-fouling, or sea organism growth, potentially improving the operation and maintenance of naval vessels.
The return of wolves to Yellowstone National Park in 1995 popularized the idea of reintroducing long-lost species to modern habitats. While scientists are still trying to fully understand the ecological consequences, the wolf's reintroduction likely benefited other species, illustrating how conservation can not just slow biodiversity loss, but even reverse it.
The intense colors of flowers have inspired us for centuries. They are celebrated through poems and songs praising the red of roses and blue of violets, and have inspired iconic pieces of art such as Vincent Van Gogh's sunflowers.
Olympians spend years training to be the best of the best. Scientists and sportspeople have spent decades researching the mechanics of the human body to ensure our elite athletes are always reaching higher, faster and stronger.
Threats to Canada's endangered woodland caribou can be traced back to spruce budworm infestations and salvage logging, says a paper co-authored by University of Saskatchewan (USask) researcher Dr. Philip McLoughlin (Ph.D.).
From habitat loss to disease, bat species across Canada are facing multiple threats. As cities expand, the large old trees that bats call home are being cleared and bats are losing their roosts.
Oregon State University research has identified a 100-million-year-old weevil unlike any other known fossilized or living weevil.
A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes.
Even in the absence of bark beetle outbreaks and wildfire, trees in Colorado subalpine forests are dying at increasing rates from warmer and drier summer conditions, found recent University of Colorado Boulder research.
A young endangered monk seal who became the mascot of a Greek island in a marine protected area after surviving a cyclone and endearing himself to locals has been killed, sparking an uproar.
Coffee prices surged this week to multi-year peaks, extending stellar gains this year after frost damaged crops in the world's biggest producer Brazil.
An unvaccinated snow leopard at the San Diego Zoo has contracted COVID-19.
Toa, the baby orca who captured hearts after he was found stranded in New Zealand waters, has lost his fight for survival, conservationists confirmed Saturday.
Shark Week is many things. First and foremost, it's a week of shark-themed documentary programming on the Discovery Channel. Now in its 33rd year, it's the longest-running cable event in history. It's the biggest audience that marine biologists and ocean conservationists get, attracting millions of viewers who might otherwise not ever think about sharks at all. It's a stage that has launched careers of shark scientists and inspired many others to pursue jobs as ocean scientists.
As the SARS-CoV-2 virus that causes COVID-19 continues to evolve, immunologists and infectious diseases experts are eager to know whether new variants are resistant to the human antibodies that recognized initial versions of the virus. Vaccines against COVID-19, which were developed based on the chemistry and genetic code of this initial virus, may confer less protection if the antibodies they help people produce do not fend off new viral strains. Now, researchers from Brigham and Women's Hospital and collaborators have created an "atlas" that charts how 152 different antibodies attack a major piece of the SARS-CoV-2 machinery, the spike protein, as it has evolved since 2020. Their study, published in Cell, highlights antibodies that are able to neutralize the newer strains, while identifying regions of the spike protein that have become more resistant to attack.
