Delineation of the Saltwater-Freshwater Interface at Selected Well Locations in the Town of Riverhead, NY

Problem The Town of Riverhead in the northeastern Suffolk County includes rural farmland and suburbs and is bounded by the Long Island Sound to the north and Peconic Bay to the southeast. Riverhead’s close proximity to saline embayments and its location along the northeastern discharge area for Long Island’s groundwater flow system makes it vulnerable to saltwater intrusion. Several public-...

Low-Flow Statistics for Indiana Streams

Indiana and Kentucky scientists have produced new low-flow statistics for Indiana streams, specifically for 7-day, 10-year low flow (7Q10); 30-day, 10-year low flow (30Q10); 1-day, 10-year low flow (1Q10); and harmonic mean streamflow. The low-flow statistics are critical for the state of Indiana to administer the National Pollutant Discharge Elimination System (NPDES) permit program,...

Invasive Carp

Adult bighead, silver, and hybrid carp are invavsive species of fish that spread quickly once they are established in a water body. These carp damage habitat and reduce water-quality for native fish. Invasive carp have been confirmed within the Wabash River basin for at least 15 years. Scientists and natural resource managers are extremely concerned about the carp migrating to the Great Lakes...

Ecological Monitoring

Scientists research biology, botany, microbiology, habitat, climate, water quality, and other fields to achieve a comprehensive view of ecosystems and their health. Ecosystems can be easily stressed by human activities, climate change, sediment, nutrients, contaminants, and many other variables. Ecosystem monitoring is critical to ecosystem health and answers important questions about the...

Pesticides

About 1 billion pounds of conventional pesticides are used each year in the United States to control weeds, insects, and other pests. The use of pesticides has resulted in a range of benefits, including increased food production and reduction of insect-borne disease, but also raises questions about possible adverse effects on the environment, including water quality. The...

Observer-free experimental evaluation of habitat and distance effects on the detection of anuran and bird vocalizations

Acoustic surveys of vocalizing animals are conducted to determine density, distribution, and diversity. Acoustic surveys are traditionally performed by human listeners, but automated recording devices (ARD) are becoming increasingly popular. Signal strength decays, or attenuates, with increasing distance between source and receiver and some...

Sex‐specific responses in neuroanatomy of hatchling American kestrels in response to embryonic exposure to the flame retardants bis(2‐ethylhexyl)‐2,3,4,5‐tetrabromophthalate and 2‐ethylhexyl‐2,3,4,5‐tetrabromobenzoate

Bis(2‐ethylhexyl)‐2,3,4,5‐tetrabromophthalate (BEH‐TEBP) and 2‐ethylhexyl‐2,3,4,5‐tetrabromobenzoate (EH‐TBB), flame retardant components of FireMaster 550® and 600® have been detected in tissues of wild birds. To address the paucity of information regarding potential impacts of flame retardants on the brain, brain volume regions of hatchling...

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...

Projected changes in climate and physical processes

In Chapter 3, we examined how climate has changed in the Mid-Atlantic region during the past century. This chapter examines how climate is expected to change during the 21st century, including changes in extreme weather events and other climaterelated processes. General circulation models, also called global climate models (GCMs), are used to...

Waterfowl spring migratory behavior and avian influenza transmission risk in the changing landscape of the East Asian-Australasian Flyway

Avian influenza has advanced from a regional concern to a global health issue with significant economic, trade, and public health implications. Wild birds, particularly waterfowl (Anseriformes), are known reservoirs for low-pathogenic avian influenza viruses (AIV) and recent studies have shown their potential in the spread of highly pathogenic...

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...

Estimating the societal benefits of carbon dioxide sequestration through peatland restoration

The Great Dismal Swamp National Wildlife Refuge (GDS) is a forested peatland that provides a number of ecosystem services including carbon (C) sequestration. We modeled and analyzed the potential capacity of the GDS to sequester C under four management scenarios: no management, no management with catastrophic fire, current management, and...

Analysis of population change and movement using robust design removal data

Open population features of the robust design allow for estimation of rates of death or permanent emigration, and closed population features enhance estimation of population sizes. We describe a similar design,...

A primary goal for Chesapeake Bay watershed restoration is to improve stream health and function in 10% of stream miles by 2025. Predictive spatial modeling of stream conditions, when accurate, is one method to fill gaps in monitoring coverage and estimate baseline conditions for restoration goals. Predictive modeling can also monitor progress as...
