From the Community: ecological research in July

Resistance to Bt crops, chaotic red queen, balancing research near Mount Saint Helens, biodiversity and species coexistence and camouflage in polymorphic Pygmy grasshoppers. Here is open-access research from the first week in July. Cropping up: From the article “Managing resistance to Bt crops in a genetically variable insect herbivore, Ostrinia nubilalis” by Megan E. O’Rourke, Cornell University, in Ecological Applications:...

Saliva from moth larva increases potato crop yields in Colombia

Many farmers throughout Latin America and around the world rely on pesticides to control pest invasions; in the case of Andean potato crops, this method is not only costly but has been shown to cause adverse health effects as well. Due to the risks involved in pesticide usage, and the ever-increasing demand for high-yield crops, new methods of controlling pest invasions are being explored by researchers regularly. And as counterintuitive as these new findings sound, ecological scientists have discovered that, in the case of Colombian potato farms in the Andes, the pests themselves could actually increase productivity.
