Evaluation Of A Habitat Capability Model For Nongame Birds In The Black Hills South Dakota PDF Download

Excerpt from Evaluation of a Habitat Capability Model for Nongame Birds in the Black Hills, South Dakota Coefficients in the habcap model quantify rela tive (o to capability of each structural stage as habitat to sustain a prescribed population density for each species. The habcap model includes separate coefficients for feeding and cover. Although feeding and cover coefficients are the same for most species, we based our test of the model on cover coefficients because cover includes nest placement in breeding territories. Abundance of bird species at each site Was the sum of observations S50'm from the count point. We used bird count data from 1992 and 1993 to test hypotheses that the observed abundance in each structural stage was similar to predicted abundance by the habcap model using chi-square goodnessof-fit tests (freese Chi-square tests were made only for structural stages with coefficients >0. Since fewer counts were made in old-growth and dry meadows, predicted abundance in these structural stages was adjusted to represent the proportion of total count days. Predicted abundance of bird species (pnj) in each structural stage (ssi) was calculated as. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
