Assessing the fit of site-occupancy models Assessing the fit of site-occupancy models
Few species are likely to be so evident that they will always be detected at a site when present. Recently a model has been developed that enables estimation of the proportion of area occupied, when the target species is not detected with certainty. Here we apply this modeling approach to data collected on terrestrial salamanders in the Plethodon glutinosus complex in the Great Smoky...

Water-quality and amphibian population data for Maryland, Washington, D.C., and Virginia, 2001-2004 Water-quality and amphibian population data for Maryland, Washington, D.C., and Virginia, 2001-2004
Data on the chemical composition of water and on amphibian populations were collected at least annually from vernal pool and stream sites in Maryland, Washington, D.C., and Virginia, from 2001 through 2004. The data were collected as part of long-term monitoring projects of the Northeast Region of the Amphibian Research and Monitoring Initiative (ARMI) of the U.S. Geological Survey...

Invasive herbivory: resident Canada geese and the decline of wild rice along the tidal Patuxent River Invasive herbivory: resident Canada geese and the decline of wild rice along the tidal Patuxent River
While concern grows over the increasing numbers of exotic mute swans (Cygnus olor) on the Chesapeake Bay, less attention seems to be given to the highly familiar and native Canada goose (Branta canadensis) which has over time developed unprecedented nonmigratory, or resident, populations. Although nuisance flocks of Canada geese have been well advertised at city parks, athletic fields...

Food habits of mute swans in the Chesapeake Bay Food habits of mute swans in the Chesapeake Bay
Unlike the tundra swan (Cygnus columbianus) that migrate to the Bay for the winter, the mute swan (Cygnus olor) is a year long resident and therefore has raised concerns among research managers over reports of conflicts with nesting native water birds and the consumption of submerged aquatic vegetation (SAV). Although data on the reduction of SAV by nesting mute swans and their offspring...

On the use of capture-recapture models in mist-net studies On the use of capture-recapture models in mist-net studies
Capture-recapture models provide a statistical framework for estimating population parameters from mist-net data. Although Cormack-Jolly-Seber and related models have recently been used to estimate survival rates of birds sampled with mist nets, we believe that the full potential for use of capture-recapture models has not been realized by many researchers involved in mist-net studies...

Ecogeomorphology of Spartina patens-dominated tidal marshes: Soil organic matter accumulation, marsh elevation dynamics, and disturbance Ecogeomorphology of Spartina patens-dominated tidal marshes: Soil organic matter accumulation, marsh elevation dynamics, and disturbance
Marsh soil development and vertical accretion in Spartina patens (Aiton) Muhl.-dominated tidal marshes is largely dependent on soil organic matter accumulation from root-rhizome production and litter deposition. Yet there are few quantitative data sets on belowground production and the relationship between soil organic matter accumulation and soil elevation dynamics for this marsh type...

Designation of the type species of Musaraneus Pomel, 1848 (Mammalia: Soricomorpha: Soricidae) Designation of the type species of Musaraneus Pomel, 1848 (Mammalia: Soricomorpha: Soricidae)
The genus name Musaraneus often is attributed to Brisson (1762), however, most of Brisson's names are unavailable. Pomel (1848) subsequently made the name Musaraneus available, but did not designate a type species. The 18 species that Pomel listed under Musaraneus currently are distributed among five modern genera, two of which (Cryptotis Pomel, 1848 and Diplomesodon Brandt, 1852) are...

Stand development on reforested bottomlands in the Mississippi Alluvial Valley Stand development on reforested bottomlands in the Mississippi Alluvial Valley
Reforestation of bottomland hardwood sites in the southeastern United States has markedly increased in recent years due, in part, to financial incentives provided by conservation programs. Currently >250,000 ha of marginal farmland have been returned to hardwood forests. I observed establishment of trees and shrubs on 205 reforested bottomlands: 133 sites were planted primarily with oak...
