Eutrophication associated with excess nutrient pollution in shallow marine ecosystems is poorly understood relative to deeper systems; this project investigates various feedbacks that may occur during eutrophication that either aggravate or partially mitigate the effects of nutrient pollution in a shallow estuary. A large reduction in nitrogen loading from the watershed allows a unique opportunity to also study the start of ecosystem recovery.
Through an interactive webinar series and accompanying online materials, this project is reaching growers and extension educators with resistance management IPM techniques. To ensure the relevance and usefulness of the information, we have worked with NY growers to evaluate their understanding of pesticide resistance and to develop IPM based plans for resistance management to train other growers in New York State, EPA Region 2 and beyond in IPM methods for pesticide resistance management.
A working group of applied and basic researchers has been established to coordinate research and extension regarding a highly damaging new disease of boxwood. University and USDA-ARS workers studying disease management and epidemiology, pathogen survival and genetics are collaborating closely to develop a highly focused effort resulting in new information and its dissemination.
The overall goal of the research in my lab is to understand the basis of inheritance in plants by studying the mechanisms of meiosis, particularly pairing of homologous chromosomes and meiotic recombination. Both pairing and recombination are critical for correct segregation of chromosomes into gametes. We want to understand these processes at the molecular level. This basic research will provide a platform for investigations on how meiotic processes can be modified to improve plant breeding methods.
The Hawaiian Islands support the greatest levels of biodiversity per unit area in the World. The geological history of the archipelago has allowed certain early colonizing groups to undergo adaptive radiations on successively emergent volcanic islands. I have been studying all of the estimated 425 native species of the beetle family Carabidae (predaceous carabid beetles), and have studied the patterns of extinction in various groups based on historical and present-day collections from the field. Recent collaboration with Dr.
The sensory representation of the external chemical world in the brain is a translation of chemical features into patterns of brain activity. It is the nature these patterns—how that are established by stimulant patterns, how they vary in a population, and ultimately how they interact with other brain functions, e.g. emotions (joy) or behavior (buying wine)—that is the object of our research. We study aroma perception in order to provide information about food composition to producers that will allow them to produce likable, healthy and more profitable products.
Worksite Wellness Resources are offered by many US corporations and can be an effective tool in recruiting and retaining workers and in helping them to maintain solid work performance. Little is known about the access of such resources to workers with disabilities. This survey research looks at access to wellness resources from the perspective of employees with disabilities.
Fertilizers prices increase and availability to rural communities in developing countries is a challenge to increasing food production. This project is generating the economic, social and biophysical knowledge base for the development of indigenous fertilizers that provide local business opportunities, are as or more effective and less expensive than imported fertilizers. Resource mapping identifies local food and processing wastes that are rich in nutrients. Innovative yet simple technology based on thermochemical and enzymatic conversion is utilized and acceptance by farmers tested.
Spotted wing drosophila (SWD) Drosophila suzukii, originally from Asia, is an invasive fruit fly that became established in NY and surrounding states in autumn of 2011. Unlike other fruit flies that typically only infest overripe and rotten fruit, female SWD oviposit in ripe fruit, thereby making them unmarketable. Economic loss projections for NY fruit are estimated at $5M. Soft-skinned fruits are at greatest risk.
We are studying the patterns of attack by insect herbivores on plants in order to both more fully understand why some plants are vulnerable to herbivory and to use our understanding to manipulate such interactions in pest control. The work involves field biology, chemical ecology, genetics and entomology. We study the interactions between plants and their pests and strongly believe in the synergy between basic and applied work.
