The U.S. Geological Survey’s Eastern Ecological Science Center is home to the Northeast Amphibian Research and Monitoring Initiative (NEARMI), one of 7 ARMI regions across the United States. NEARMI works on public lands in thirteen states from Maine to Virginia, including many National Parks and National Wildlife Refuges.
Dr. Evan H. Campbell Grant coordinates ARMI activities in the Northeast by conducting and developing amphibian research and monitoring projects. Research by NEARMI staff at the US Geological Survey's Eastern Ecological Science Center provides public land managers (like the National Park Service and US Fish and Wildlife Service) information they need on the current status of amphibians, how amphibian distributions have change or are expected to change over time, and threats to populations. Data from the Northeast is also used collaboratively to evaluate questions about amphibian declines, threats, and changes over time at larger spatial scales.
NEARMI works to provide timely science not only about common, widespread species, but also to assist with conservation of species at risk and those being evaluated for listing under the Endangered Species Act. Work on these species may include field surveys, data analysis, or decision support for local managers. Many NEARMI projects are long-term collaborations and involve decision science, a set of tools and techniques for evaluating multiple goals and unknowns to aid resource management decisions.

Detecting individuals of amphibian and reptile species can be a daunting task. Detection can be hindered by various factors such as cryptic behavior, color patterns, or observer experience. These factors complicate the estimation of state variables of interest (e.g., abundance, occupancy, species richness) as well as the vital rates that induce changes in these state variables (e.g., survival probAuthorsMarc J.

No abstract available.AuthorsS.D. Mattfeldt, E.H.C. GrantEstimating the abundance of mouse populations of known size: promises and pitfalls of new methods
Knowledge of animal abundance is fundamental to many ecological studies. Frequently, researchers cannot determine true abundance, and so must estimate it using a method such as mark-recapture or distance sampling. Recent advances in abundance estimation allow one to model heterogeneity with individual covariates or mixture distributions and to derive multimodel abundance estimators that explicitAuthorsP.B.

This is the first book to examine the latest methods in analyzing presence/absence data surveys. Using four classes of models (single-species, single-season; single-species, multiple season; multiple-species, single-season; and multiple-species, multiple-season), the authors discuss the practical sampling situation, present a likelihood-based model enabling direct estimation of the occupancy-relaAuthorsD.I.

The Amphibian Research and Monitoring Initiative (ARMI) is an innovative, multidisciplinary program that began in 2000 in response to a congressional directive for the Department of the Interior to address the issue of amphibian declines in the United States. ARMI’s formulation was cross-disciplinary, integrating U.S. Geological Survey scientists from Biology, Water, and Geography to develop a couAuthorsErin Muths, Alisa L. Gallant, Evan H.

KearneyStream salamander species richness and abundance in relation to environmental factors in Shenandoah National Park, Virginia
Stream salamanders are sensitive to acid mine drainage and may be sensitive to acidification and low acid neutralizing capacity (ANC) of a watershed. Streams in Shenandoah National Park, Virginia, are subject to episodic acidification from precipitation events. We surveyed 25 m by 2 m transects located on the stream bank adjacent to the water channel in Shenandoah National Park for salamanders usiAuthorsEvan H. Campbell Grant, Robin E. Jung, Karen C. RiceAmphibian Research and Monitoring Initiative (ARMI): A successful start to a national program in the United States
Most research to assess amphibian declines has focused on local-scale projects on one or a few species. The Amphibian Research and Monitoring Initiative (ARMI) is a national program in the United States mandated by congressional directive and implemented by the U.S. Department of the Interior (specifically the U.S. Geological Survey, USGS). Program goals are to monitor changes in populations of amAuthorsGary M. Fellers, Erin Muths, C. Kenneth Dodd, D. Earl Green, William A. Battaglin, P. Stephen Corn, M. J. Adams, Alisa L.

WallsDouble-observer approach to estimating egg mass abundance of vernal pool breeding amphibians
Interest in seasonally flooded pools, and the status of associated amphibian populations, has initiated programs in the northeastern United States to document and monitor these habitats. Counting egg masses is an effective way to determine the population size of pool-breeding amphibians, such as wood frogs (Rana sylvatica) and spotted salamanders (Ambystoma maculatum). However, bias is associatedAuthorsEvan H. Campbell Grant, Robin E. Jung, James D. Nichols, James E. HinesLarge-scale habitat associations of four desert anurans in Big Bend National Park, Texas
We used night driving to examine large scale habitat associations of four common desert anurans in Big Bend National Park, Texas. We examined association of soil types and vegetation communities with abundance of Couch's Spadefoots (Scaphiopus couchii), Red-spotted Toads (Bufo punctatus), Texas Toads (Bufo speciosus), and Western Green Toads (Bufo debilis).

Biological indicators are critical to the protection of small, headwater streams and the ecological values they provide. Maryland and other state monitoring programs have determined that fish indicators are ineffective in small streams, where stream salamanders may replace fish as top predators. Because of their life history, physiology, abundance, and ubiquity, stream salamanders are likely repAuthorsM.T. Southerland, R.E. Jung, D.P. Baxter, I.C. Chellman, G. Mercurio, J.H.

The Shenandoah salamander (Plethodon shenandoah), known from isolated talus slopes on three of the highest mountains in Shenandoah National Park, is listed as state-endangered in Virginia and federally endangered under the U.S. Endangered Species Act.
