MIAMI--As the world enters a next wave of the ongoing COVID-19 pandemic, we are aware now more than ever of the importance of a healthy immune system to protect ourselves from disease. This is not only true for humans but corals too, which are in an ongoing battle to ward off deadly diseases spreading on a reef.
The research team found a common insecticide, fipronil, and related compounds were more toxic to stream communities than previous research has found.
UC assistant professor Latonya Jackson conducted experiments with North American freshwater fish called least killifish. She found that fish exposed to estrogen in concentrations of 5 nanograms per liter in controlled lab conditions had fewer males and produced fewer offspring. Scientists have found estrogen at as much as 16 times that concentration in streams adjacent to sewage treatment plants.
The critically endangered vaquita has survived in low numbers in its native Gulf of California for hundreds of thousands of years, a new genetic analysis has found. The study found little sign of inbreeding or other risks often associated with small populations.
A study quantified the size and age of the forests that grow naturally in degraded and abandoned areas, creating 131 benchmark maps for Brazil. The Amazon has the most restored forests and the Atlantic Rainforest biome has the oldest.
A new study of a 14,000-year record, published in Science Advances, shows that seabird poop transformed an entire ecosystem in the Falkland Islands, raising questions about the birds' survival and the potential impact of climate change on sensitive terrestrial-marine ecosystems
A 14,000-year paleoecological reconstruction of the sub-Antarctic islands led by University of Maine researchers has found that seabird establishment occurred during a period of regional cooling 5,000 years ago. Their populations, in turn, shifted the Falkland Islands ecosystems through the deposit of high concentrations of guano that helped nourish tussac, produce peat and increase the incidence of fire.
University of Oregon biologists have used the model organism Caenorhabditis elegans to identify molecular mechanisms that produce DNA damage in sperm and contribute to male infertility following exposure to heat.
By examining the poop of the fringe-lipped bat (Trachops cirrhosus), a team at the Smithsonian Tropical Research Institute (STRI) encountered surprising results about its eating habits and foraging abilities.
A "safety net" made up of multiple ambitious and interlinked goals is needed to tackle nature's alarming decline, according to an international team of researchers analyzing the new goals for biodiversity being drafted by the UN's Convention on Biological Diversity (CBD).
