Winter 2001

Based on research conducted by NCBI’s comparative genomics group, the database of Clusters of Orthologous Groups of proteins (COGs) represents a phylogenetic classification of proteins encoded in complete genomes.

Fall-to-Winter and Winter Movements of Pheasants in lowa

Ring-necked pheasant (Phasianus colchicus) movements were studied in south-central Hamilton County, Iowa, during the fall and winter of 1966-67. Fall-to-winter movements of 23 pheasants averaged 0.66 mile. The greatest movement recorded was 2.45 miles. There was no evidence of oriented movement either in direction or to specific wintering areas. The mean winter movement of 43 pheasants was 0.20...
