To restore the grasslands of the Great Plains, a Nebraska ecologist says, bring back high intensity fires Ecologist Dirac Twidwell wants to change the way we think about prescribed burns. The University of Nebraska professor says he can harness extreme fire to restore grasslands on the Great Plains—and, with the help of the Nebraska Intelligent MoBile Unmanned Systems (NIMBUS) Lab,…

Zika funding fails, Democrats cite controversial amendments Politics undermine latest effort at funding response to Zika outbreak. Appropriations break down, omnibus or continuing resolution likely Failure to enact any appropriations measures through regular order prompts focus on stop-gaps.

One hundred and thirty years ago, the volcano Krakatoa erupted in what is now Indonesia, unleashing a cataclysm locally and years of cool temperatures and rain globally. On the far side of the world, a bumper crop of saguaro cacti were getting their start in life in Arizona’s Sonoran Desert. Many of the large exemplars of the famous cacti standing…

The aggressive, day-biting Asian tiger mosquito, Aedes albopictus, has spread with global trade from its native home in the tropics and subtropics of Southeast Asia. First observed in Houston, Texas, in 1987, it rapidly spread through the interstate system in the the United States. Its range is pushing northward into New York and Pennsylvania. Does Ae. albopictus crowd out other…

Invasive Aedes aegypti and Aedes albopictus are the principal vectors of dengue, chikungunya, and Zika viruses in the Americas. These species often find themselves in competition for mates and resources for their young. Cross-mating between the species creates infertile eggs and permanent sterilization of A. aegypti females. Lounibos and colleague Steven Juliano of Illinois State University described the causes and…

As an example of the costs of mosquito suppression, three imperiled native plants in the Lower Florida Keys suffer indirectly from the spraying of insecticides in housing developments flanking National Key Deer Refuge. Harris will present her work in a poster session on Conservation at the 2016 Annual Meeting of the Ecological Society of America in southern Florida this August. PS…

Some species of mosquitoes spread dangerous human diseases. But mosquitoes have their own parasites, like the protozoan Ascogregarina barretti, which is related to the organisms that cause malaria and toxoplasmosis, and infects the native North American mosquito Aedes triseriatus. The invasive mosquito, Aedes japonicus, a recent arrival in North America, does not contract As. barretti. Will the presence of Ae. japonicus dilute the…

Beyond the blood meal, mosquitoes need sugar and safe and nurturing pools to cradle their eggs and emerging larva. Fallen leaves floating in still water (like residential stormwater drainage ditches) make appealing hatcheries for the common house mosquito (Culex pipiens), a carrier of West Nile virus. At the 2016 Annual Meeting of the Ecological Society in Fort Lauderdale, Florida, this…
