Restoring prairie and fighting wildfire with (drone launched) fire(balls)

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, he has created a small drone that launches ping-pong...

Asian tiger mosquito thrives in New York

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 mosquito species? Katz surveyed the mosquito species...

Battle at the bloodmeal lek #ESA2016

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 consequences of...

Invasive mosquito helps break the spread of a parasite

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...

De-Extinction, a risky ecological experiment

Genetic engineering may allow us to rebirth close facsimiles of extinct species. But would bringing back a few individuals of a famously gregarious bird like the passenger pigeon truly revive the species, when the great oak forests that sustained them are gone? And if it succeeds, what if the birds don’t fit in anymore in our changed world? Experience with biological invasions leads guest writer Dave Strayer, a distinguished...

Kill da wabbit

A New Brunswick family helps remove invasive snowshoe hares from a group of remote Bay of Fundy Islands, five decades after introducing them as Bowdoin professor Nathaniel Wheelwright recounts in the February Natural History Note for Frontiers in Ecology and the Environment. Too much of an adorable thing. Snowshoe hares like this one, photographed in its winter finery in Denali National Park, are native to North America and range...
