US consumers prefer the idea of using fresh water for any watering needs. In most cases, plants irrigated with recycled water saw no negative impact when compared to the same types of plants irrigated with pure, non-recycled water.
Experimentalists conducted a simulation of future conditions in the Red Sea caused by global warming and acidification, while simultaneously increasing levels of nutrients such as nitrate and phosphate. They found that when nitrate and phosphate were added, the coral thermal resilience was compromised while algal growth benefited from excess CO2 and nutrients. Algal dominance over corals in the reef means losing all of the beauty and biodiversity of the coral reefs.
A new study shows the Earth's climate would increase by 4 degrees Celsius, compared to pre-industrial levels, before the end of 21st century. The study also projects precipitation changes in association with a 4 degrees Celsius global warming above the pre-industrial period using the available RCP8.5 experiments of CMIP5 models.
By the late 21st century, if atmospheric greenhouse gas concentrations reach worst-case projections, Floridians could experience summer heatwaves three times more frequently, and each heatwave could last six times longer and be much hotter than at present, according to Meteorology Professor Shawn M. Milrad of Embry-Riddle Aeronautical University.
Chemical signatures in shale, the Earth's most common sedimentary rock, point to a rapid rise of land above the ocean 2.4 billion years ago that possibly triggered dramatic changes in climate and life.
Increased carbon dioxide in the atmosphere will reduce the nutritional value of rice, according to an international research team that analyzed rice samples from field experiments started by a University of Tokyo professor. Populations in countries with both the highest rice consumption and lowest gross domestic product may experience more malnutrition as the nutritional value of low-cost staple foods like rice declines.
Higher levels of carbon dioxide will result in major reductions in the nutritional quality of rice -- a food staple for half the world's population, a new study finds. It was based on research in China and Japan on 18 common strains of rice. The study reports declines in protein, iron and zinc in rice grown in controlled atmospheric CO2 concentrations that scientists think will exist by the end of the 21st century.
The large and small, beautiful and bizarre are among the newly discovered animals, plants and microbes announced by the College of Environmental Science and Forestry (ESF) as the Top 10 New Species for 2018.
Eastern hemlock forests have been declining due to a non-native insect pest. A new study from The Condor: Ornithological Applications presents some of the best data showing how the decline of a single tree species leads to the disappearance of birds specialized to them. The data also indicate birds associated with non-hemlock habitat features are spreading into former hemlock forests. A single insect species has led to a less diverse bird community across this landscape.
If resources are limited and tough to find, reproductive efforts may fail. In these situations, it may be in an animal's best interests to not defend a territory or to breed at all, but rather focus its efforts on surviving to the next breeding season. A new study from The Auk: Ornithological Advances presents some of the best evidence on how changes in environmental conditions, specifically droughts, impact the social and reproductive behavior of birds.
