Physical events, environments, and geological—Ecological interactions at Mount St. Helens: March 1980–2004
The diversity and intensity of volcanic processes during the 1980 eruption of Mount St. Helens affected a variety of ecosystems over a broad area and created an exceptional opportunity to study interactions of geophysical and ecological processes in dynamic landscapes. Within a few hours on the morning of May 18, 1980, a major explosive eruption of Mount St. Helens affected thousands of square kil

Plasma lipid metabolites and refueling performance of Semi palmated Sandpipers at migratory stopovers
Assessing stopover habitat quality and refueling performance of individual birds is crucial to the conservation and management of migratory shorebirds. Plasma lipid metabolites indicate the trajectory of mass change in individuals and may be a more accurate measure of refueling performance at a particular site than static measures such as nutrient reserves. We measured lipid metabolites of Semip

Population trends of North American sea ducks as revealed by the Christmas Bird Count
Relative to other waterfowl, sea ducks are not well understood, yet evidence from a variety of analyses suggests that as many as 10 of the 15 species of North American sea ducks may be declining in population. However, because of the difficulty of conducting surveys of breeding populations and the lack of range-wide winter surveys, few data are available to assess the population trends of sea duc

Population trends of North American sea ducks based on Christmas Bird Count and Breeding Bird Survey data
Due to the difficulty of conducting range-wide surveys of either breeding or wintering populations, few data are available to assess the population trends of sea ducks with confidence. We analyze sea duck data from the Audubon Christmas Bird Count (CBC) using hierarchical modeling methods that control for varying effort among circles and over time. These procedures allow us to assess early-winte

Predicting bird response to alternative management scenarios on a ranch in Campeche, Mexico
We developed models to predict the potential response of wintering Neotropical migrant and resident bird species to alternative management scenarios, using data from point counts of birds along with habitat variables measured or estimated from remotely sensed data in a Geographic Information System. Expected numbers of occurrences at points were calculated for 100 species of birds, under current

Protecting visitor health in beach waters of Lake Michigan: problems and opportunities
In this paper, we will review past research on Escherichia coli (E. Coli) and its relationship to recreational waters. Further, we will discuss current monitoring research and future prospects for improving monitoring efficiency to protect the health of beachgoers.
