Emerging Methods for Detection and their Potential for Inventorying Brook Trout Populations in Streams of the Western Adirondacks

Background Deoxyribonucleic acid (DNA) is the hereditary material in organisms that contains the biological instructions for building and maintaining them. The chemical structure of DNA is the same for all organisms, but differences exist in the order of the DNA building blocks, known as base pairs. Unique sequences provide a means to identify individual species and detect their presence...

Water-Quality Assessments of Principal Aquifers

Background A major focus of the NAWQA Program in its second decade (2002-2013) is on regional- and national-scale assessments of groundwater-quality status and trends in principal aquifers. The U.S. Geological Survey Office of Groundwater has identified 62 principal aquifers in the U.S. ( U.S. Geological Survey, 2003 ). About 1/3 of the Nation's principal aquifers are the focus of water-...

Hurricane Sandy -- Science to support coastal resilience

Coastal Hydrology and Storm Surge Storm-surge is one of the most powerful and destructive elements of major storm events. Excessively high tides associated with storms can flood and inundate coastal areas, often moving sediment and altering coastal landscapes and drainages. USGS provides critical expertise in measuring storm surge and assessing conditions both before and after the storm....

Quantitative Assessment of Water Quality in Upper Esopus Creek: Fish, Macroinvertebrates, Periphyton, Turbidity, and Nutrients

Background The Esopus Creek is located in the Catskill Mountains of New York State and is part of the New York City (NYC) drinking water supply system. The basin was dammed in 1915 to form the Ashokan Reservoir splitting the creek into Upper (upstream of the reservoir) and Lower segments. The drainage area of Upper Esopus Creek, between the source (Winisook Lake) and the Ashokan Reservoir is a...

Natural Methane Occurrence in Water Wells of South-Central New York State- Evaluation of Topographic Position and Hydrogeologic Setting

INTRODUCTION Naturally occurring methane has been noted at some locations in the upper Devonian shale bedrock and in overlying glacial deposits in parts of Broome, Tioga, and Chemung Counties in south-central New York State (Williams, 2010). Systematic sampling of water wells for dissolved methane is needed to determine if the topographic and hydrogeologic setting of a well is related to...

Whole Ecosystem Restoration Through Liming of Honnedaga Lake Tributary Watersheds

Summary Acid rain levels in the Adirondack region have substantially declined and recovery from acid rain is underway. Recovery is being limited by the depletion of soil calcium that occurred over past decades. Not only is calcium needed for neutralizing acidity, it is an essential nutrient for terrestrial and aquatic ecosystems. However, recovery of soil calcium has not yet been observed....

Digital representation of exposures of Precambrian bedrock in parts of Dickinson and Iron Counties, Michigan, and Florence and Marinette Counties, Wisconsin

The U.S. Geological Survey (USGS) conducted a program of bedrock geologic mapping in much of the central and western Upper Peninsula of Michigan from the 1940s until the late 1990s. Geologic studies in this region are hampered by a scarcity of bedrock exposures because of a nearly continuous blanket of unconsolidated sediments resulting from...

China, the United States, and competition for resources that enable emerging technologies

Historically, resource conflicts have often centered on fuel minerals (particularly oil). Future resource conflicts may, however, focus more on competition for nonfuel minerals that enable emerging technologies. Whether it is rhenium in jet engines, indium in flat panel displays, or gallium in smart phones, obscure elements empower smarter,...

Linking animals aloft with the terrestrial landscape

Despite using the aerosphere for many facets of their life, most flying animals (i.e., birds, bats, some insects) are still bound to terrestrial habitats for resting, feeding, and reproduction. Comprehensive broad-scale observations by weather surveillance radars of animals as they leave terrestrial habitats for migration or feeding flights can be...

Occupancy in community-level studies

Another type of multi-species studies, are those focused on community-level metrics such as species richness. In this chapter we detail how some of the single-species occupancy models described in earlier chapters have been applied, or extended, for use in such studies, while accounting for imperfect detection. We highlight how Bayesian methods...

The aerosphere as a network connector of organisms and their diseases

This can have profound consequences for evolutionary diversification, energy and nutrient transfers, and the spread of infectious diseases. The latter is of particular consequence for human populations, since migratory birds...

Reduced swimming performance repeatedly evolves upon loss of migration in landlocked populations of Alewife
