In Missouri forests, dense thickets of invasive honeysuckle decrease the light available to other plants, hog the attention of pollinators and offer nutrient-stingy berries to migrating birds. They also release toxins that decrease the germination of nearby native plants. Why, then, do studies of invasive species come to different conclusions about their effects and lead some organizations to suggest we accept their presence?

Hydraulically fractured natural gas wells are producing less wastewater per unit of gas recovered than conventional wells would. But the scale of fracking operations in the Marcellus shale region is so vast that the wastewater it produces threatens to overwhelm the region's wastewater disposal capacity, according to new analysis by a CHANS-Net researcher at Duke and a colleague at Kent State.

How do people adapt to forest fires?

That question underlies the interdisciplinary Forest People Fire (FPF) project and is the focus of the next U.S. Forest Service Landscape Science webinar on Jan. 22 at 1 p.m. EST.

CHANS-Net members Jose Manuel Fragoso, Jeff Luzar, and Kirsten Silvius have two new papers in Human Ecology. Both examine the interactions between varous Western religions and the religions of indigenous peoples. They also examine the implications of changes in belief systems because of interactions on biodiversity.

Over past decades, many areas of the forested Amazon basin have become a patchwork of farms, pastures and second-growth forest as people have moved in and cleared land -- but now many are moving out, in search of economic opportunities in newly booming Amazonian cities. The resulting depopulation of rural areas, along with spreading road networks and increased drought are causing more and bigger fires to ravage vast stretches, say researchers in a new study.

Africa's Lake Victoria, the world’s second-largest body of freshwater, is in rapid transition. Conflict, progress, and population shifts all weigh on its waters. Impacts directly affect the basic food-security of the 40-million people inhabiting its basin.

When foot-and-mouth disease swept through the British countryside in early 2001, more than 10 million sheep, cattle and pigs were slaughtered to control the disease. Despite the devastation, the disease was contained within 10 months, due in part to the availability of finely detailed farm data, which enabled mathematical modelers to make accurate predictions about the spread of the disease and suggest optimal ways of managing it.

The most deadly type of malaria in humans and the one most prevalent in Africa is very sensitive to climate. Previously published scientific studies put the optimal temperature for malaria transmission from mosquitos to humans at 31 degrees C (88 degrees F), but according to a new mathematical model, the temperature for peak transmission of the parasite, Plasmodium falciparum, is much, much lower.
