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...

Water-quality data from ground- and surface-water sites near concentrated animal feeding operations (CAFOs) and non-CAFOs in the Shenandoah Valley and eastern shore of Virginia, January-February, 2004 Water-quality data from ground- and surface-water sites near concentrated animal feeding operations (CAFOs) and non-CAFOs in the Shenandoah Valley and eastern shore of Virginia, January-February, 2004
Concentrated animal feeding operations (CAFOs) result from the consolidation of small farms with animals into larger operations, leading to a higher density of animals per unit of land on CAFOs than on small farms. The density of animals and subsequent concentration of animal wastes potentially can cause contamination of nearby ground and surface waters. This report summarizes water...

A new species of Lonchophylla Thomas (Chiroptera: Phyllostomidae) from Ecuador A new species of Lonchophylla Thomas (Chiroptera: Phyllostomidae) from Ecuador
We describe Lonchophylla orcesi, sp. nov., from the Choco, a region of high biotic diversity, endemism, and rainfall along the western Andean slopes and Pacific lowlands of Colombia and Ecuador. One of the largest known Lonchophylla, it occurs sympatrically with at least two other species of Lonchophylla including the similar, but somewhat smaller L. robusta. We also recognize L. concava...

Population trends of North American sea ducks as revealed by the Christmas Bird Count Population trends of North American sea ducks as revealed by the Christmas Bird Count
Relative to other waterfowl, sea ducks are not well understood, yet evidence from a variety of analyses suggests that as many as 10 of the 15 species of North American sea ducks may be declining in population. However, because of the difficulty of conducting surveys of breeding populations and the lack of range-wide winter surveys, few data are available to assess the population trends...
