Bottomland hardwood establishment and avian colonization of reforested sites in the Mississippi Alluvial Valley Bottomland hardwood establishment and avian colonization of reforested sites in the Mississippi Alluvial Valley
Reforestation of bottomland hardwood sites in the Mississippi Alluvial Valley has markedly increased in recent years, primarily due to financial incentive programs such as the Wetland Reserve Program, Partners for Wildlife Program, and state and private conservation programs. An avian conservation plan for the Mississippi Alluvial Valley proposes returning a substantial area of cropland...

U-Pb zircon ages and Pb isotope geochemistry of gold deposits in the Carolina slate belt of South Carolina U-Pb zircon ages and Pb isotope geochemistry of gold deposits in the Carolina slate belt of South Carolina
Volcanic rocks of the Persimmon Fork Formation host the largest known gold mines of the Carolina slate belt. U-Pb (SHRIMP) zircon ages have been obtained from rocks closely associated with pyrite-enargite-gold deposits at Brewer (quartz-topaz rhyolite breccia from the argillic alteration zone in the Brewer pit and felsic ash-flow tuff from the quartz sericite alteration zone), from the...

Late Neogene and Quaternary evolution of the northern Albemarle Embayment (mid-Atlantic continental margin, USA) Late Neogene and Quaternary evolution of the northern Albemarle Embayment (mid-Atlantic continental margin, USA)
Seismic surveys in the eastern Albemarle Sound, adjacent tributaries and the inner continental shelf define the regional geologic framework and provide insight into the sedimentary evolution of the northern North Carolina coastal system. Litho- and chronostratigraphic data are derived from eight drill sites on the Outer Banks barrier islands, and the Mobil #1 well in eastern Albemarle...

Mineral of the month: tin Mineral of the month: tin
Tin was one of the first metals discovered by humans and, like most metals, tin is rarely used by itself. Most tin is used as a protective coating or as an alloy with other metals in a diverse range of commercial and defense applications.

Mineral of the month: potash Mineral of the month: potash
In 1807, Sir Humphrey Davy discovered a metal during the electrolysis of potassium hydroxide; he named the metal potassium because it came from potash recovered from wood ashes. The four types of potash are the water-soluble compounds potassium chloride, potassium sulfate, potassium-magnesium sulfate and potassium nitrate. The early uses of potash were in glass and soap manufacturing, as...

Exploration Exploration
The worldwide budget for nonferrous, nonfuel mineral exploration was expected to increase by 58 percent in 2004 from the 2003 budget, according to Metals Economics Group (MEG) of Halifax, Nova Scotia. The increase comes two years after a five-year period of declining spending for mineral exploration (1998 to 2002). Figures suggest a subsequent 27 percent increase in budgeted expenditures...

Book review: Shorebirds of North America: the photographic guide Book review: Shorebirds of North America: the photographic guide
As stated in the preface of this new guide, shorebirds are among our most engaging birds. Their ecology and behavior are the subjects of numerous ornithological studies, their identification can challenge the skills of the most serious birdwatchers, and people with a casual interest in birds are captivated by the antics of Sanderlings (Calidris alba) chasing waves along a beach. While...

An objective method to determine an area's relative significance for avian conservation An objective method to determine an area's relative significance for avian conservation
Land managers are often concerned with providing habitat affords the 'best habitat for songbirds.' However, unless management simply is directed at rare species it may not be clear which habitats or management options are best. A standard, quantifiable measure to compare the significance of different tracts of land or competing management techniques for avian conservation would benefit...

Home range and survival of breeding painted buntings on Sapelo Island, Georgia Home range and survival of breeding painted buntings on Sapelo Island, Georgia
The southeastern United States population of the painted bunting (Passerina ciris) has decreased approximately 75% from 1966–1996 based on Breeding Bird Survey trends. Partners in Flight guidelines recommend painted bunting conservation as a high priority with a need for management by state and federal agencies. Basic information on home range and survival of breeding painted buntings...

Camera-trap study of ocelot and other secretive mammals in the northern Pantanal Camera-trap study of ocelot and other secretive mammals in the northern Pantanal
Reliable information on abundance of the ocelot (Leopardus pardalis) is scarce. We conducted the first camera-trap study in the northern part of the Pantanal wetlands of Brazil, one of the wildlife hotspots of South America. Using capture-recapture analysis, we estimated a density of 0.112 independent individuals per km2 (SE 0.069). We list other mammals recorded with camera traps and...

Agronomie implications of waterfowl management in Mississippi ricefields Agronomie implications of waterfowl management in Mississippi ricefields
Ricefields are important foraging habitat for waterfowl and other waterbirds in several North American wintering areas, including the Mississippi Alluvial Valley (MAV). Rice growers are likely to adopt management practices that provide habitat for waterfowl if agronomic benefits also occur. Therefore, we conducted a replicated field experiment during autumn through spring 1995–1997 to...
