The Holdridge model of ecological classification is applied to the state of Oregon resulting in a life zone map. Vegetation maps are employed to evaluate the units defined by the model. The life zone map collates with vegetation maps and the patterns appear quite rational.
Data from 186 mountain cottontail rabbits (Sylvilaus nuttallii) captured 455 times by livetrapping and from 46 rabbits collected by shooting were evaluated to determine monthly densities, survival rates, extent of movements, dispersion in relation to habitat types, and criteria for determining ages of mountain cottontails. Estimates of density computed for...
Genetic variability in natural populations of Douglas-fir was
studied at molecular level by investigating the variations of some
primary gene products, i. e. enzymes. Using the techniques of disc
gel electrophoresis and biochemical staining, the isoenzyme patterns
of leucine aminopeptidase, esterase and glutamate oxaloacetate
transaminase are characterized in young seedlings...
