Bird and Terrestrial Species Conservation

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.

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.

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.

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...

Avian influenza virus in the aquatic environment: Surveillance in waterfowl habitat on the Delmarva Peninsula.

At more than five feet tall with brilliant white plumage, black primary feathers, a red cap, and yellow eyes, the highly endangered Whooping Crane ( Grus americana) is one of the most spectacular birds native to North America. In 1942 there were fewer than 20 birds in the flock that migrates from Wood Buffalo National Park in Canada to Aransas National Wildlife Refuge in Texas. An additional six...

The Challenge: The genomic revolution is giving wildlife biologists new tools to assess the role of wildlife in spreading diseases that affect human populations. Peptide arrays are a high throughput technology that gives unprecedented breadth and depth of information about the immune system. We are using peptide arrays to assess the immune responses of Chesapeake Bay waterfowl to avian influenza...

The Challenge: In eastern North America there is a viral disease called Eastern Equine Encephalitis, or EEE. This virus is transmitted among native bird species by the mosquito, Culiseta melanura, but does not cause disease in these passerine species. However, the virus is capable of causing severe disease or death in horses, some game bird species, humans and whooping cranes. In the fall of 1984...

This project seeks to improve our understanding of how domestic ducks move throughout the market chain in China and the role this may play in the amplification and spread of avian influenza viruses.

The Challenge: The health of the abundant waterfowl species of Chesapeake Bay has become a major concern due to the spread of Avian Influenza (AI) across North America and the role of waterfowl as a vector of AI. For decades, the health of the Bay’s waterfowl has been affected by the degradation of water quality and food supply due to industrial contaminants,agricultural run-off, pollution from...

Feral and free-ranging domestic cats (Felis catus) have strong negative effects on wildlife, particularly in island ecosystems such as the Florida Keys. We deployed camera traps to study free-ranging cats in National Wildlife Refuges and state parks on Big Pine Key and Key Largo and used spatial models to estimate cat population dynamics and stable isotope analyses to examine cat diets. Top models...
