Investigating the impacts (alone, and combined) of high temperature and drought on corn production. This includes identifying possible management and breeding strategies to reduce or eliminate the negative impacts of these climate stresses on corn production.
Powdery mildew is one of the world's most destructive diseases of grapevines. We know that infection of grapevines occurs as soon as they begin to grow in spring, but epidemics seem to stall for about six weeks and go nowhere fast. We've found that it's our cold nights that are suppressing the disease. Two modes of action are suggested. First, cold nights stimulate a temporary defense response in the youngest, and ordinarily most-susceptible, leaves. Second, cold causes direct damage to the mildew colonies.
Effective waste management can turn unwanted waste products into resources and reduce disposal costs. Waste management is part of every industry, but a waste product produced by one business can be a resource to another. Residuals from animal, food and yard waste, as well as industrial and household waste, have the potential to be valuable in agriculture and horticulture production as erosion control and nutrient and carbon sources, and in energy production and other industrial processes.
I develop cost-effective methods of producing food fish and shrimp in an environmentally sustainable manner and work with developing countries to assist in implementing new businesses.
eClips is a digital database of 10,000 clips and more than 40 podcasts, focused on entrepreneurship, business, and leadership. The material is based on hundreds of in-depth interviews as well as business presentations. eClips makes it possible for business people (including small business owners and entrepreneurs), educators, and students to find targeted and focused information, because it is organized by entrepreneur, company, demographics, topics, and keywords.
Our consensus paper in Science projected that coral reefs will be unable to grow calcareous skeletons within the next 50 years due to rising carbon dioxide (acidification). Our research paper in PLoS Biology showed for the first time that increases in infectious coral disease can be driven by climate warming. This economically important ecosystem will be destroyed by a combination of warming and acidification in the next few decades.
We use the tools of molecular biology to document the biodiversity of birds and other animals and to explain their behaviors, ecologies and evolutionary histories. Our research program integrates studies of evolutionary trees (phylogenetics), speciation, hybridization, animal behavior, ecology, disease ecology and conservation genetics.
Selectable marker genes are widely used for the efficient transformation of crop plants. In most cases, selection is based on genes for antibiotic or herbicide resistance, which are most efficient. Due mainly to consumer and grower concerns, considerable effort has been put into developing strategies to eliminate marker genes from plants after transformation. However, these methods are generally of low efficiency.
The goal of this project is to lay grounds for transmission genetics in arbuscular mycorrhizal (AM) fungi (Glomeromycota). We use a cosmopolitan species Glomus etunicatum as a model. Our objectives are to investigate: (i) evolution of the ribosomal RNA genes, (ii) the reproductive mode, and (iii) the developmental patterns of spore formation. We discovered that (i) the polymorphism of rRNA genes in the G. etunicatum lineage is inconsistent with the concerted evolution model of rRNA, which is one of the paradigms of evolutionary biology, (ii) the population structure of G.
Fruit farmers and turfgrass managers must produce pesticide and fertilizer records on demand for EPA Worker Protection, NYS Dept. of Environmental Conservation, food safety audits, food processors, produce brokers, eco-markets, organic certifiers, etc. Trac Software has been documented to improve pesticide application record keeping and to facilitate generating reports. Since its invention in 2003 by Juliet Carroll, NYS IPM Program, over 500 fruit farmers in New York and worldwide have obtained Trac Software, and 98 percent continue using it.
