Bees of the Northeastern U.S.
Declines of pollinators have engendered worldwide concern, but trends in the faunas of most insect pollinators, including bees, remain uncertain. We are studying the bee fauna of southern Rhode Island to provide baseline information about the current fauna, and information about bee-flower interactions.
Dysbiosis, immunomodulation, and health effects of agricultural pesticides in wild prairie grouse
Agrochemical pollution poses a severe threat to biodiversity. Agrochemicals can detrimentally affect wildlife growth, development, survival, reproduction, and immune responses, which facilitates emergence and spread of infectious diseases that may cause unusually high mortality. Animal microbiota plays a fundamental role in host’s food detoxification and defense against pathogens, regulates...
Spatio-Temporal Statistical Models for Forecasting Climate Change Effects on Bird Distribution
Ecological indicators of climate change are needed to measure concurrent changes in ecological systems, inform management decisions, and forecast the consequences of climate change. We seek to develop robust bird-based, climate-change indicators using North American Breeding Bird Survey data.
Conservation Genetics and Genomics of the Narrowly Endemic Island Marble Butterfly Euchloe ausonides insulanus
The island marble butterfly ( Euchloe ausonides insulanus ) was first discovered on Vancouver Island, Canada in 1861. Based on morphological characteristics, it has been described as a subspecies of Euchloe ausonides . After a collection was made in 1908 on Gabriola Island, Canada, the island marble was not seen again until 1998 on San Juan Island, Washington, USA. Recent surveys have determined...
Development of Next Generation Techniques of fecal samples collected from nestling cactus wren
Coastal cactus wren populations have declined in southern California over the last three decades. In San Diego County, this decline has been especially noticeable in the Otay area, which in 2014 supported 14 territories on conserved lands. In the past, there were 25-53 active territories reported for this same area, with the highest estimate in 1992. There is also concern the number of active...
Fall Survival of American Woodcock on Cape May, NJ
The American woodcock is a popular game bird in much of eastern North America. The woodcock population declined between 1968- 2000 at an annual rate of 2.3% in the Eastern region and 1.6% in the Central region. Estimated annual survival of woodcock banded in the Eastern region was estimated to be 0.354 for the period 1967-74. Estimates for the migration period, a period when substantial mortality...
Pre-listing Science Support in the Northeast
We are working closely with multiple partners to provide updated information, model potential outcomes, and identify key uncertainties relevant to amphibian and reptile species proposed for listing in the northeast US. We also provide timely science to partners to assist in recovery of listed species, which may involve field research, data analysis, or decision support.
Deriving Spatial Waterfowl Inputs for Disease Risk Modeling
This project is an effort to create spatially and temporally explicit models for waterfowl distribution across the United States for use in avian influenza transmission risk modeling.
Improving Forage for Honey Bees on USDA Conservation Lands: A Pilot Study for Testing Sampling Methods and Hypothesis Development
Commercial beekeepers have been bringing their bees to the Northern Great Prairie (NGP) for many decades due to the availability of nectar and pollen-rich plants in abundant grasslands.
Determining carcass scavenging rates on major rivers for oil spill response and NRDAR
We are conducting avian carcass detection and persistence trials to generate an estimator to correct for the avian injuries that are not found after a oil spill on inland rivers.
Does tropospheric ozone, resulting from fossil fuel combustion, disrupt bee pollination?
The Challenge: Pollinators such as bees use floral volatiles to guide them to flowers. Tropospheric ozone produced from fossil fuel combustion products can breakdown floral volatiles. Interference with bee pollination threatens habitat quality and biodiversity and the security of the US food supply system.
Environmental Management of Vector-borne Diseases
Effective management programs for vector-borne pathogens, such as West Nile Virus and the Lyme disease spirochete, are necessary to protect public health. However, some vector control methods, such as landscape manipulations and pesticide applications, can also adversely affect nontarget species and environmentally sensitive natural systems. Efficient targeting and integration of vector control...
