When species are introduced by humans into marine habitats, they can disrupt their new environment, according to a study at KAUST, which also identified key species for conservation efforts to focus on.
Shark and ray species commonly caught in the Mediterranean and Black seas are not being reported in official statistics, new research from the Sea Around Us initiative at the University of British Columbia shows.
New research by a global team of scientists has resulted in significant strides in ornithological classification and identified possible causes of diversity among modern bird species.
Svalbard reindeer adapt to dramatic climate change in a way that may foreshadow the future for other arctic species
A project conducted by researchers in Brazil and the US investigated bacteria living in symbiosis with insects as a source for novel drugs.
Deep in the ocean or underground, where there is no oxygen, Geobacter bacteria "breathe" by projecting tiny protein filaments called "nanowires" into the soil, to dispose of excess electrons resulting from the conversion of nutrients to energy.
The research was part of the thesis of PhD student Hanna Nyborg Støstad, investigating the peculiar spiral shape of songbird sperm. Støstad compared sperm cells of 36 bird species, from house sparrows to tree swallows, and found that species whose sperm had a particularly distinct spiral or corkscrew shape also had sperm with high average swimming speed. However, those species also tended to have high rates of abnormal or damaged sperm.
For the first time scientists have found an organism that can produce chlorophyll but does not engage in photosynthesis.
When Susannah Lerman talked with fellow researchers and friends about her study of the effects of less frequent lawn mowing to improve habitat for native bees, the response she heard most had nothing to do with bees. "The first thing people said was that letting the grass get longer would invite ticks," said Lerman, a research ecologist with the USDA Forest Service's Northern Research Station. "It was clear that before we could make the case for promoting lawns as bee habitat, we had to understand the tick risk."
For years, scientists have assumed that when top predators are reintroduced to an ecosystem, the effects are predictable: The ecosystem will return to how it was before the predators were wiped out.
Until recently, five ebolavirus species were known, with three of these - Bundibugyo, Sudan and Zaire ebolaviruses - associated with large human outbreaks. The latter is responsible for the devastating 2013-16 outbreak in West Africa and the ongoing outbreak in the Democratic Republic of Congo.
CORVALLIS, Ore. - A groundbreaking two-year study in southern Oregon found greater abundance and diversity of wild bees in areas that experienced moderate and severe forest fires compared to areas with low-severity fires.
It's not fun when a fungus contaminates crops. Safe native fungi, however, show promise in the fight against toxic fungal contamination.
Dogs that receive omega-3 fatty acid supplements or have hypothyroidism may be less likely to develop T-zone lymphoma (TZL). Those are two findings from Morris Animal Foundation-funded researchers at Colorado State University, who studied associations of environment and health history of the disease among golden retrievers. They published their results in the Journal of Veterinary Internal Medicine.
