Longevity of nonsprouting Ceanothus Longevity of nonsprouting Ceanothus
Evidence is presented indicating species of Ceanothus in the subgenus Cerastes are generally longer-lived than species in the subgenus Euceanothus. It is proposed that this is due, at least in part, to the unique stem morphology of the former. The stems of these plants have a ribbed appearance which arises when branches die. This longitudinal channeling results in less nonphotosynthetic...

Utilization of Skylab (EREP) system for appraising changes in continental migratory bird habitat Utilization of Skylab (EREP) system for appraising changes in continental migratory bird habitat
The author has identified the following significant results. Surface water statistics using data obtained by supporting aircraft were generated. Signature extraction and refinement preliminary to wetland and associated upland vegetation recognition were accomplished, using a selected portion of the aircraft data. Final classification mapping and analysis of surface water trends will be

Gut morphology of mallards in relation to diet quality Gut morphology of mallards in relation to diet quality
Digestive organ lengths, weights, and volumes in each of three groups of mallards (Anas platyrhynchos) were determined at the end of a 21-day period, during which one group was starter (control diet), another group was fed whole corn (low fiber content), and the third fed alfalfa pellets (high fiber content) to demonstrate the adaptive efficiency of the waterfowl diets of varying quality...
