Popis: | Determining the effects of plant community changes on animal populations is an important area of ecological research. We compared condition, population characteristics, and diet composition of white-tailed deer (Odocoileus virginianus) from 2 root-plowed (low brush diversity) and 2 untreated (high brush diversity) sites in the eastern Rio Grande Plains of Texas to test the hypothesis that root plowing, which decreases woody species diversity-, reduced deer habitat quality. We collected 8 adult female white-tailed deer from each site every 3 months for 6 sampling periods. We assessed condition from several physiological, reproductive, and digestive indices and determined food habits by microhistological analysis of rumen samples. We estimated population size from helicopter surveys |
