Improving Our Ability to Forecast Tidal Marsh Response to Sea Level Rise

Our overall objective is to understand what controls the vulnerability of coastal marshes to risks associated with global change drivers and rising sea levels. Fundamental questions pertaining to coastal wetland vulnerability still need to be addressed. What factors explain spatial and geographic variation in tidal wetland vulnerability? How do short term climatic events (storms) influence the...

Toxicity of the Non-Steroidal Anti-Inflammatory Drug Diclofenac

One of the hallmarks of non-steroidal anti-inflammatory drugs (NSAID) is the difficulty in predicting potentially toxic effects.Diclofenac is one such NSAID that devastated Asian vulture populations when they fed upon carcasses of livestock treated with the NSAID diclofenac.Because these drugs are widely used, we studied the potential hazard of diclofenac in New World vultures.

Response of Migrating Birds to Hurricane Sandy

The Challaenge: Each autumn, millions of landbirds migrate southward from breeding areas in the U.S. and Canada. Because these migrations occur during hurricane season, the impacts of hurricanes on migrating birds and their en route resting and foraging sites (stopover sites) are a real concern. Hurricane Sandy occurred late in the landbird migration season. By the time the storm made landfall...

Radar Analysis of Fall Migration Stopover Sites in the Northeastern U.S.

The Challenge: Most landbird conservation efforts focus on protecting or enhancing breeding habitat. For migratory species, however, mortality is highest during the biannual migration periods. In fall, juvenile birds are making their first migratory flights; their success, and that of adult birds, depends on availability of suitable sites to safely rest and forage. Identifying important...

In-Air and Underwater Hearing Abilities of Seabirds

As diving foragers, sea ducks are vulnerable to underwater anthropogenic activities, including naval sonar activity and gillnet fisheries.  Bycatch in gillnets is a principle driver of mortality for sea ducks, killing hundreds of thousands of seabirds annually. To reduce gillnet bycatch, underwater hearing tests were conducted on affected sea duck species to assist with possible development of...

Automated quantification of surface water inundation in wetlands using optical satellite imagery

We present a fully automated and scalable algorithm for quantifying surface water inundation in wetlands. Requiring no external training data, our algorithm estimates sub-pixel water fraction (SWF) over large areas and long time periods using Landsat data. We tested our SWF algorithm over three wetland sites across North America, including the...
