Plasma lipid metabolites and refueling performance of Semi palmated Sandpipers at migratory stopovers Plasma lipid metabolites and refueling performance of Semi palmated Sandpipers at migratory stopovers
Assessing stopover habitat quality and refueling performance of individual birds is crucial to the conservation and management of migratory shorebirds. Plasma lipid metabolites indicate the trajectory of mass change in individuals and may be a more accurate measure of refueling performance at a particular site than static measures such as nutrient reserves. We measured lipid metabolites...

Winter status of White-eyed Vireos in northeastern Louisiana Winter status of White-eyed Vireos in northeastern Louisiana
In December 2004, February 2005, and June 2005, we recaptured a White-eyed Vireo (Vireo griseus) that was banded on 19 May 2004 at the same location on the Tensas River National Wildlife Refuge, Madison Parish, LA. This is the first documented permanent resident White-eyed Vireo outside of resident populations known from Florida and southern Texas. This individual appears to be resident...

Groundwater control of mangrove surface elevation: shrink and swell varies with soil depth Groundwater control of mangrove surface elevation: shrink and swell varies with soil depth
We measured monthly soil surface elevation change and determined its relationship to groundwater changes at a mangrove forest site along Shark River, Everglades National Park, Florida. We combined the use of an original design, surface elevation table with new rod-surface elevation tables to separately track changes in the mid zone (0?4 m), the shallow root zone (0?0.35 m), and the full...

Multi-stage sampling for large scale natural resources surveys: A case study of rice and waterfowl Multi-stage sampling for large scale natural resources surveys: A case study of rice and waterfowl
Large-scale sample surveys to estimate abundance and distribution of organisms and their habitats are increasingly important in ecological studies. Multi-stage sampling (MSS) is especially suited to large-scale surveys because of the natural clustering of resources. To illustrate an application, we: (1) designed a stratified MSS to estimate late autumn abundance (kg/ha) of rice seeds in...

Current range of the eastern population of Painted Bunting (Passerina ciris). Part 1: Breeding Current range of the eastern population of Painted Bunting (Passerina ciris). Part 1: Breeding
This paper presents the current breeding range of Painted Bunting (Passerina ciris) in a series of maps and a narrative, in particular that of the eastern population, which is restricted to the states of North Carolina, South Carolina, Georgia, and Florida. Some conservation measures are recommended to protect this population. In light of the extensive habitat loss in the Outer Coastal...

A comparison of campfire impacts and policies in seven protected areas A comparison of campfire impacts and policies in seven protected areas
Using resource-monitoring data from seven protected areas, the effectiveness of three campfire policies—campfire ban, designated campfires, and unregulated campfires—were assessed based on the number of fire sites and the amount of tree damage. Results indicate that unregulated campfire policies permitted substantial numbers of fire sites and tree damage in campsites, although fire bans...

Quantifying production of salmon fry in an unscreened irrigation system: A case study on the Rangitata River, New Zealand Quantifying production of salmon fry in an unscreened irrigation system: A case study on the Rangitata River, New Zealand
Diversion of out-migrant juvenile salmon into unscreened irrigation and hydroelectric canals is thought to have contributed significantly to declining populations of anadromous salmonids in the Pacific Northwest but is seldom studied in detail. Here we describe a program to study the fate of Chinook salmon Oncorhynchus tshawytscha fry diverted into the unscreened Rangitata Diversion Race...
