Sex determination of the Acadian Flycatcher using discriminant analysis Sex determination of the Acadian Flycatcher using discriminant analysis

I used five morphometric variables from 114 individuals captured in Arkansas to develop a discriminant model to predict the sex of Acadian Flycatchers (Empidonax virescens). Stepwise discriminant function analyses selected wing chord and tail length as the most parsimonious subset of variables for discriminating sex. This two-variable model correctly classified 80% of females and 97% of...

Relation of water quality to land use in the drainage basins of four tributaries to the Toms River, New Jersey, 1994-95 Relation of water quality to land use in the drainage basins of four tributaries to the Toms River, New Jersey, 1994-95

The influence of land use on the water quality of four tributaries to the Toms River, which drains nearly one-half of the Barnegat Bay wateshed, was studied during the initial phase of a multiyear investigation. Water samples were collected from and streamflows were measured in Long Swamp Creek, Wrangel Brook, Davenport Branch, and Jakes Creek during periods of base flow and stormflow in...

Trace-element concentrations in streambed sediment across the conterminous United States Trace-element concentrations in streambed sediment across the conterminous United States

Trace-element concentrations in 541 streambed-sediment samples collected from 20 study areas across the conterminous United States were examined as part of the National Water-Quality Assessment Program of the U.S. Geological Survey. Sediment samples were sieved and the
