There is growing public concern in the Northeastern U.S. over pesticide use on school and community playing fields. However, there are limited options available for alternative pest management practices for school grounds. Our project will assess the impact of repetitive overseeeding as an alternative pest management practice on school sports fields.

2014 to 2015

Large-scale conifer die-offs cause devastating environmental impacts in North America. While the linkages with bark beetle infestation driven by climate change have been well-studied, the comprehensive effects of die-off on biological communities have not. Using pristine, impacted and recovering forests in Alaska, we will examine these whole biome impacts. There is increasing realization that habitat perturbations damage human interests as well as impacting biodiversity – and should be subjected to a holistic approach.

2014 to 2017

This project involves the design, implementation, and evaluation of tools that incorporate computational analysis techniques to support frame reflection into the processes of online political engagement. This work involves both the application of existing analytic methods and the development of novel computational techniques, as well as evaluation in two real-world settings: in public deliberative forums and with readers of political blogs.

2014 to 2016

In this project, we aim to characterize the mechanisms by which gut microbes, either pathogenic or commensals, affect the gut epithelium. In particular, we are interested in understanding how microbes alter stem cell activity, and the cross talk between immune and developmental pathways in the gut.

Ecological research is increasingly concentrated at particular locations or sites. How well does site-based research represent broader areas? We provided an overview of this issue based on observations for the Hubbard Brook (HB) site. The feasibility of scaling up from intensive sites depends upon the phenomenon of interest and the characteristics of the site. For example, the HB site is representative of Northern Forest region in regard to effects of and recovery from acid rain.

2014 to 2017

We are investigating the impacts of 5 different fungal endophytes on root damage by white grub larvae of the European chafer in turf-type tall fescue. We are also evaluating the impact of endophytes on the ability of turfgrasses to recover from herbivore damage. Our findings indicate that the impacts of fungal endophytes on herbivore damage and recovery are species specific.

2014 to 2017

We are evaluating the impact of pest management intensity along with the effects of pesticide identity, frequency, and rate of application on beneficial soil microbes and invertebrates. Our goal is to identify practices that meet current pest management needs, but also preserve soil ecological services.

2013

The Tata-Cornell Agriculture and Nutrition Initiative (TCi) is a long-term research initiative focusing on the design and evaluation of innovative interventions linking agriculture, food systems, human nutrition, and poverty in India. TCi focuses on action research to 1) increase household income and local food supply through productivity growth; 2) increase micronutrient food availability through crop diversification and food fortification programs; 3) ensure intra-household equity in food access through behavior change; and 4) improve access to clean drinking water and sanitation.

2013 to 2016

This project has sought to elucidate the life cycles of two rust diseases that are relatively new to New York, pear trellis rust and Japanese apple rust. Finding the rest of the life cycle (as it is being carried out in New York) has required the use of molecular techniques to identify the rust on its juniper hosts. Recently surveys were successful in identifying a host for the pear trellis rust, and two hosts for the Japanese apple rust, providing the green industry with information needed to make good choices for what ornamentals should not be paired together in the landscape.

2013 to 2015

The project seeks to sustainably graduate at least 50,000 food insecure households in four regions in Ethiopia. The aim is is to enhance the capacity of smallholders to withstand social and environmental shocks and improve their productivity.
