A new study by the Wildlife Conservation Society and James Cook University says that coral reefs in Aceh, Indonesia are benefiting from a decidedly low-tech, traditional management system that dates back to the 17th century.
Efforts to enhance wildlife habitat by controlling vegetation could actually cause more harm than good. Wyoming big sagebrush is often manipulated to decrease its density and encourage the growth of herbaceous plants. However, this may bring about declines in the population of birds, elk, and other animals.
On the heels of one the worst U.S. droughts in more than half a century, a new study raises questions about the future of one of the most integral members of stream ecosystems throughout the Southeast – the salamander. Research from Wake Forest University shows how salamanders react to drought, shedding light on the impact of climate change and increased urbanization.
Arizona State University researchers have developed a new software system capable of estimating greenhouse gas emissions across entire urban landscapes, all the way down to roads and individual buildings.
Warming temperatures in Ohio are a key driver behind changes in the state’s landscape, and non-native plant species appear to be responding more strongly than native wildflowers to the changing climate, new research suggests.
Weed scientists in Oregon have found that the timing of herbicide application along with reseeding of native grasses offers the best recipe for restoring native grasslands while controlling invasive weeds. Grasslands are a valuable resource for ecosystems, providing soil conservation, food and fiber production, and wildlife habitat. When threatened by invading exotic species, the quality and quantity of forage for wildlife can be reduced, fire frequencies can be altered, soil moisture and nutrients can be depleted, and the costs of land management can increase.
A new study reveals that a significant amount of carbon released into the atmosphere from lakes and rivers in Southern Québec, Canada, is very old – approximately 1,000 to 3,000 years old – challenging the current models of long-term carbon storage in lakes and rivers.
For some people, scientific facts help determine what they believe about an issue. But for others, political views trump scientific facts and determine what information they will accept as true. It’s a phenomenon that is particularly prevalent on the issue of climate change.
Coral reefs – ecosystems of incredible environmental and economic value – are showing evidence of significant degradation, but do not have to be doomed. We can make a difference.
