Use of detrended correspondence analysis in evaluating factors controlling species composition of periphyton Use of detrended correspondence analysis in evaluating factors controlling species composition of periphyton
Detrended correspondence analysis (DCA) was evaluated for its usefulness in elucidating relationships among samples and among species of periphyton in an oligotrophic stream, and for its effectiveness in displaying major gradients where an experimental gradient (copper) affecting species composition was imposed. It was highly sensitive to differences among samples and consistently...

Use of miniroutes and Breeding Bird Survey data to estimate abundance Use of miniroutes and Breeding Bird Survey data to estimate abundance
1. Information on relative abundance is easily obtained and adds greatly to the value of an atlas project. 2. The Breeding Bird Survey (BBS) provides annual counts (birds per 50 roadside stops) that can be used to: (1) map relative abundance by physiographic region within a state or province, (2) map relative abundance on a more local scale by using results from individual routes, or (3)...

Variations in the global carbon cycle during the Cretaceous related to climate, volcanism, and changes in atmospheric CO2 Variations in the global carbon cycle during the Cretaceous related to climate, volcanism, and changes in atmospheric CO2
The stratigraphic record from both deep-sea and shallow-water depositional environments indicates that during late Aptian through Cenomanian time (1) global climates were considerably warmer than at present; (2) latitudinal gradients of atmospheric and oceanic temperatures were considerably less than at present; (3) rates of accumulation of organic matter of both marine and terrestrial...
