Hydrologic Effects of Pymatuning Earthquake

Within hours after the Pymatuning earthquake of September 25, 1998, in northwestern Pennsylvania, local residents reported wells becoming dry, wells beginning to flow, and the formation of new springs. About 120 household-supply wells reportedly went dry within 3 months after the earthquake. About 80 of these wells were on a ridge between Jamestown and Greenville, where water-level declines of...

Survival and Recruitment of Common Eiders in the Gulf of Maine

The dresseri race of common eiders breed from central Labrador to southern Maine and winter from Newfoundland to Massachusetts. The breeding population in the mid-1980s was estimated to be 71,000 pairs, of those 40% were in Maine. In Maine, nesting eiders increased from a few pairs in the early 1900s to approximately 28,000 pairs in 1989. Although the number of birds seems to be stable, the...

Analyses of Woodcock Singing Ground Surveys in the Northeast

The Challenge: Research goals of this project seek to determine if survey routes for American woodcock are sampling represenative habitats and whether routes are distributed proportionally to early successional habitats and biophysical regions across Maine, Vermont, and New Hampshire. If routes are not representatively distributed (i.e., biased), we will evaluate the effects of this bias on...

Monitoring migration of American woodcock past 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. The annual migration of woodcock from the breeding grounds to their wintering areas has been of interest to biologists and hunters. Migration corridors along the Atlantic coast, such as...

Estimation of Density and Abundance of Biological Populations on National Parks and Wildlife Refuges Through Distance Sampling

The Challenge: Assessing the status and trends of populations of biological organisms is an important management goal and a recurrent theme in USGS research. Often, the most basic question of “how many are there?” remains elusive, thus making management decisions more difficult. This study continues a long-term commitment of technical support for the use of distance sampling for wildlife...

Hydrologic controls of methane dynamics in karst subterranean estuaries

Karst subterranean estuaries (KSEs) extend into carbonate platforms along 12% of all coastlines. A recent study has shown that microbial methane (CH4) consumption is an important component of the carbon cycle and food web dynamics within flooded caves that permeate KSEs. In this study, we obtained high‐resolution (~2.5‐day) temporal records of...

Eco‐evolutionary rescue promotes host–pathogen coexistence

Emerging infectious pathogens are responsible for some of the most severe host mass mortality events in wild populations. Yet, effective pathogen control strategies are notoriously difficult to identify, in part because quantifying and forecasting pathogen spread and disease dynamics is challenging. Following an outbreak, hosts must cope with the...

North Atlantic midlatitude surface-circulation changes through the Plio-Pleistocene intensification of northern hemisphere glaciation

The North Atlantic Current (NAC) transports warm salty water to high northern latitudes, with important repercussions for ocean circulation and global climate. A southward displacement of the NAC and Subarctic Front, which separate subpolar and subtropical water masses, is widely suggested for the Last Glacial Maximum (LGM) and may have acted as a...
