The project focuses on educating agencies, public officials, and other stakeholder groups about issues surrounding invasive, non-native forest pests. The potential social, economic, and ecological impacts of these forest pests is staggering. Decisions need to be made to manage pest populations in order to minimize impacts. Effective outreach and extension activities that communicate accurate and up-to-date scientific knowledge are necessary to facilitate this decision making process.
We are using molecular genetic and genomic technologies to unravel the mechanisms of pathogenicity in agriculturally important plant pathogenic bacteria, and to determine how new pathogenic species emerge in agricultural systems.
On-going global climate change will likely have pronounced impacts on plant and animal populations, yet we have only a rudimentary understanding of what those impacts will be. Our research focuses on the reproductive behavior and physiology of a common migratory bird – the black-throated blue warbler – breeding in the Northeastern United States, and is focused on understanding how these animals will respond to the changes in the environment (e.g. weather and food abundance) that are predicted to occur within the next several decades.
This program trains dairy plant and regulatory personnel on the proper design, construction, inspection and use of HTST pasteurizers to produce safe dairy products.
Water-related issues continue to grow more critical in many parts of the world. Resolving these issues will depend in part on education to ensure responsible future behavior for tomorrow`s leaders. Teaching activities from Project WET`s Curriculum Guide for K-12 will help ensure responsible and sustainable behavior toward water.
An agriculture and food technology park can serve as an excellent mechanism to transfer technology derived at state agricultural experiment stations. At the same time, the park stimulates the creation and growth of new businesses and accompanying jobs.
The mission of the Sun Grant Initiative is to: 1) enhance national energy security through development, distribution, and implementation of biobased energy technologies; 2) promote biobased diversification and environmental sustainability of America's agriculture; and 3) promote opportunities for biobased economic diversification in rural communities.
Growers and consumers detest rotten onions. They cause financial losses to both groups. Most rots are caused by bacterial pathogens, and there are no good methods available to prevent the problem. If the losses from rot can be reduced or eliminated, everyone will be happier! In 2007, my program began to address bacterial disease problems of onions.
In field experiments, we are investigating the conditions that alter the consumptive and nonconsumptive effects of predators. We have selected plant resistance, predator density, and predator ontogeny as likely important factors. We will elucidate the mechanisms generating these effects using plants with genetically modified resistance responses, an examination of herbivore and predator behavior, and chemical assays of plant resistance. These mechanisms will include effects of the predator on herbivores and effects of the predator directly on plants.
Bacteria that cause vascular diseases in plants, including grapes, were discovered to migrate against the transpiration-induced flow of xylem sap using pilus-mediated twitching movements. Colonization of the vascular system by these bacteria was examined in vitro using nanofabricated microfluidic chambers in which the bacteria were discovered to auto-aggregate into cell masses that plugged the channels.
