Modeling seasonal interactions in the population dynamics of migratory birds Modeling seasonal interactions in the population dynamics of migratory birds
Understanding the population dynamics of migratory birds requires understanding the relevant biological events that occur during breeding, migratory, and overwintering periods. The few available population models for passerine birds focus on breeding-season events, disregard or oversimplify events during nonbreeding periods, and ignore interactions that occur between periods of the...

General constraints on sampling wildlife on FIA plots General constraints on sampling wildlife on FIA plots
This paper reviews the constraints to sampling wildlife populations at FIA points. Wildlife sampling programs must have well-defined goals and provide information adequate to meet those goals. Investigators should choose a State variable based on information needs and the spatial sampling scale. We discuss estimation-based methods for three State variables: species richness, abundance...

Atlantic Flyway review: Region IV, Piedmont-Coastal Plain, Fall 2004: Robbins Nest, Laurel, MD (390-0765) Atlantic Flyway review: Region IV, Piedmont-Coastal Plain, Fall 2004: Robbins Nest, Laurel, MD (390-0765)
The continuing decline in migratory species is depressing. For a 'migration station' to report Northern Cardinal as the species most commonly banded during the autumn months came as a real shock, especially when the cardinal was so far ahead of second-place catbird. I caught twice as many cardinals as all sparrows combined (including juncos), and the total for cardinals came within ten...

Checklist of the terrestrial vertebrates of the Guiana Shield Checklist of the terrestrial vertebrates of the Guiana Shield
Distributions are given for 1850 species of terrestrial vertebrates in the Guiana Shield region of northeastern South America, with introductory text by the authors of each section. Distributions cover the three Guianas (Guyana, Surinam, and French Guiana), and the states of the Venezuelan Guayna (Amazonas, Bolivar, and Delta Amacuro), and in some cases the states of the Brazilian...
Management and protection protocols for the threatened Piping Plover (Charadrius Melodus) on Cape Hatteras National Seashore, North Carolina Management and protection protocols for the threatened Piping Plover (Charadrius Melodus) on Cape Hatteras National Seashore, North Carolina
Executive Summary 1. The breeding population of the piping plover (Charadrius melodus), a federally-threatened shorebird, at Cape Hatteras National Seashore (CAHA) declined from 15 pairs/yr to 3 pairs/yr from 1989-2004. A population of this size may face immediate risk of extirpation from several sources. At several former breeding sites at CAHA, there have been no nesting pairs in...

Disturbance of eelgrass Zostera marina by commercial mussel Mytilus edulis harvesting in Maine: Dragging impacts and habitat recovery Disturbance of eelgrass Zostera marina by commercial mussel Mytilus edulis harvesting in Maine: Dragging impacts and habitat recovery
We studied the effects of commercial harvest of blue mussels Mytilus edulis on eelgrass Zostera marina L. in Maquoit Bay, Maine, USA, at a hierarchy of scales. We used aerial photography, underwater video, and eelgrass population- and shoot-based measurements to quantify dragging impacts within 4 sites that had been disturbed at different times over an approximate 7 yr interval, and to...

Prenesting use of intertidal habitats by piping plovers on South Monomoy Island, Massachusetts Prenesting use of intertidal habitats by piping plovers on South Monomoy Island, Massachusetts
On barrier islands, piping plovers commonly select nest sites adjacent to bay-side intertidal flats, pools, or other moist substrates that are protected from ocean waves (Patterson et al. 1991, Elias et al. 2000, Keane 2002). During the fledging period, these areas often support more terrestrial arthropods than adjacent ocean beaches (Loegering and Fraser 1995, Elias et al. 2000). Plover...
