Wood Thrush movements and habitat use: Effects of forest management for Red-cockaded Woodpeckers Wood Thrush movements and habitat use: Effects of forest management for Red-cockaded Woodpeckers
We monitored adult and juvenile breeding-season movements and habitat use of radio-tagged Wood Thrushes (Hylocichla mustelina) at the Piedmont National Wildlife Refuge, central Georgia, USA. We investigated the effects that management for Red-cockaded Woodpeckers (Picoides borealis), thinning and burning >30 year old loblolly pine (Pinus taeda) habitat, had on Wood Thrushes, a ground...

Seasonal distribution and abundance of fishes and decapod crustaceans in a Cape Cod estuary Seasonal distribution and abundance of fishes and decapod crustaceans in a Cape Cod estuary
Sampling in several habitat types (sand/mud, eelgrass, sand, gravel, macroalgae/mud) during all seasons with a variety of gears in Nauset Marsh, Massachusetts during 1985-1987 found a fauna consisting of 35 fish and 10 decapod crustacean species. Although most of the abundant species were found in several habitat types, species richness and habitat use appeared to be highest for...

Blood selenium concentrations and enzyme activities related to glutathione metabolism in wild emperor geese Blood selenium concentrations and enzyme activities related to glutathione metabolism in wild emperor geese
In 1998, we collected blood samples from 63 emperor geese (Chen canagica) on their breeding grounds on the Yukon-Kuskokwim Delta (YKD) in western Alaska, USA. We studied the relationship between selenium concentrations in whole blood and the activities of glutathione peroxidase and glutathione reductase in plasma. Experimental studies have shown that plasma activities of these enzymes...

Nineteenth century mercury hazard to wading birds and cormorants of the Carson River, Nevada Nineteenth century mercury hazard to wading birds and cormorants of the Carson River, Nevada
Contemporary mercury interest relates to atmospheric deposition, contaminated fish stocks and exposed fish-eating wildlife. The focus is on methylmercury (MeHg) even though most contamination is of inorganic (IoHg) origin. However, IoHg is readily methylated in aquatic systems to become more hazardous to vertebrates. In response to a classic episode of historical (1859–1890) IoHg...

Demography of a population collapse: The Northern Idaho ground squirrel (Spermophilus brunneus brunneus) Demography of a population collapse: The Northern Idaho ground squirrel (Spermophilus brunneus brunneus)
We studied the demography of a population of Northern Idaho ground squirrels (Spermophilus brunneus brunneus) in Adams Co., Idaho. The population was completely censused yearly from 1987 to 1999, during which time it declined from 272 to 10 animals. The finite population growth rate, based on a Leslie matrix model of average life-history parameters, was only 0.72 (i.e., significantly

A monitoring protocol to assess tidal restoration of salt marshes on local and regional scales A monitoring protocol to assess tidal restoration of salt marshes on local and regional scales
Assessing the response of salt marshes to tidal restoration relies on comparisons of ecosystem attributes between restored and reference marshes. Although this approach provides an objective basis for judging project success, inferences can be constrained if the high variability of natural marshes masks differences in sampled attributes between restored and reference sites. Furthermore...

The horse and deer flies (Diptera: Tabanidae) of Rhode Island The horse and deer flies (Diptera: Tabanidae) of Rhode Island
The Tabanidae of Rhode Island were surveyed using Rhode Island canopy traps placed at 20 locations in the state during the summers of 1999 and 2000. In total, 5,120 flies were collected, which included 55 species in the genera Chrysops, Hybomitra, Tabanus, Merycomyia, and Stonemyia. Distributional and ecological information is provided for each species in Rhode Island.

Supplemental planting of early successional tree species during bottomland hardwood afforestation Supplemental planting of early successional tree species during bottomland hardwood afforestation
Reforestation of former bottom land hardwood forests that have been cleared for agriculture (i.e., afforestation) has historically emphasized planting heavy-seeded oaks (Quercus spp.) and pecans (Carya spp.). These species are slow to develop vertical forest structure. However, vertical forest structure is key to colonization of afforested sites by forest birds. Although early...
