Q&A on Review and Revision of the National Ambient Air Quality Standard for Ozone

Here are answers to some questions about the recent announcement by the U.S. Environmental Protection Agency regarding a proposed revision to the National Ambient Air Quality Standard (NAAQS) for ozone from Dr. H. Christopher Frey, Distinguished University Professor at North Carolina State University and chair of the EPA’s Clean Air Scientific Advisory Committee.

Warmer Temperatures Limit Impact of Parasites, Boost Pest Populations

Research shows that some insect pests are thriving in warm, urban environments and developing earlier, limiting the impact of parasitoid wasps that normally help keep those pest populations in check.

Urban Heat Boosts Some Pest Populations 200-Fold, Killing Red Maples

New research from North Carolina State University shows that urban “heat islands” are slowly killing red maples in the southeastern United States. One factor is that researchers have found warmer temperatures increase the number of young produced by the gloomy scale insect – a significant tree pest – by 300 percent, which in turn leads…

Dam Removal Improves Shad Spawning Grounds, May Boost Survival Rate

Research from North Carolina State University finds that dam removal improves spawning grounds for American shad and seems likely to improve survival rates for adult fish, juveniles and eggs – but for different reasons.

Urbanization, Higher Temperatures Can Influence Butterfly Emergence Patterns

An international team of researchers has found that a subset of common butterfly species are emerging later than usual in urban areas located in warmer regions, raising questions about how the insects respond to significant increases in temperature.

Where Credit Is Due: How Acknowledging Expertise Can Help Conservation Efforts

Scientists know that tapping into local expertise is key to conservation efforts aimed at protecting biodiversity – but researchers rarely give credit to these local experts. Now some scientists are saying that’s a problem, both for the local experts and for the science itself. To address the problem, a group of scientists is calling for…

Rainforest Life: Food Versus Fear

For a rainforest animal like the agouti, life revolves around the tension between food and fear. While foraging for seeds from the black palm tree, the rabbit-sized rodent has to avoid hungry ocelots. Living in an area where food is scarce greatly increases an agouti’s willingness to venture out of its burrow between sunset and…

Tree Change: Is Raleigh Becoming More Like Baltimore?

Could Raleigh, proudly known as the City of Oaks, end up having much less tree cover, like Baltimore? Though it’s not likely that Raleigh will have to rethink its New Year’s Eve drop of the giant acorn any time soon, planners and policy makers need to take steps to prevent the City of Oaks from…

Researchers Develop System for Assessing How Effective Species Are at Pollinating Crops

From tomatoes to pumpkins, most fruit and vegetable crops rely on pollination by bees and other insect species – and the future of many of those species is uncertain. Now researchers from North Carolina State University are proposing a set of guidelines for assessing the performance of pollinator species in order to determine which species…

How Computer Models Help Keep the Lights on In Kenya

In Kenya, water is power. Literally. And to keep the lights on, Kenyan authorities want to know how much water they can expect in upcoming rainy seasons. That’s where computer models come in. Fifty-eight percent of Kenya’s power supply stems from the country’s hydropower system in the Tana River basin. That system will shut down…

Protecting 17 Percent of Earth’s Land May Preserve 67 Percent of Its Plant Species

Protecting key regions that comprise just 17 percent of Earth’s land may help preserve more than two-thirds of its plant species, according to a new study by an international team of scientists, including a biologist from North Carolina State University. The researchers from Duke University, NC State and Microsoft Research used computer algorithms to identify the…

New Carnivore in the Cloud Forest

A two-pound mammal that looks like a cross between a house cat and a teddy bear has a claim to fame as the first new carnivore species discovered in the Western Hemisphere in 35 years. Today, scientists in Washington, D.C., and Raleigh unveiled the olonguito (oh-lin-GHEE-toe), a member of the same family as raccoons, coatis,…

No Rest for the Tornado

Do tornadoes take the weekends off? Researchers from NC State University examined the question of the connection between tornado frequency and aerosol pollution, and found that any link between the two is tenuous at best. Aerosols are tiny airborne particles, many of which are associated with air pollution. Previously, some scientists had hypothesized that these aerosols,…
