Shell-Dropping Behavior Of Western Gulls (Larus Occidentalis), John L. Maron
Shell-Dropping Behavior Of Western Gulls (Larus Occidentalis), John L. Maron
Biological Sciences Faculty Publications
Westem Gulls (Larus occidentalis) at Bodega Bay, California drop shelled prey items to break them. I presented Washington clams (Saxidomus nuttalli) of known weight to free-flying gulls to investigate factors affecting shell-dropping behavior. All adult gulls dropped clams, whereas only 55% of immature gulls did so. The other 45% of immature gulls that were given clams pecked at them on the ground instead. Gulls dropped clams on both hard and soft substrates. Flight distance and kleptoparasitism seemed important in influencing drop location. Adult Western Gulls dropped heavy clams from lower heights than they dropped light clams. …
Structure Of Maltoheptaose By Difference Fourier Methods And A Model For Glycogen, E. Goldsmith, S. Sprang, R. Fletterick
Structure Of Maltoheptaose By Difference Fourier Methods And A Model For Glycogen, E. Goldsmith, S. Sprang, R. Fletterick

The structure of the glucose heptamer, maltoheptaose, has been determined by difference Fourier analysis at 0.25 nm resolution through its binding to phosphorylase a. It is a left-handed helical structure, with 6.5 glucose residues per turn and a rise per residue of 2.4 Å. The molecule shows short-range order when no protein is present to stabilize its conformation in solution. With one exception, the individual torsion angles between sugar residues vary over a narrow range and preserve a good O(2)O(3′) hydrogen bond. The length of an individual chain for glycogen can be extrapolated from the maltoheptaose data …
Recreation Opportunity Spectrum With Implications For Wildlife-Oriented Recreation, Perry J. Brown
Recreation Opportunity Spectrum With Implications For Wildlife-Oriented Recreation, Perry J. Brown
Forest Management Faculty Publications
Resource planning has undergone transitions over the years from a site to area to regional orientation and from a single function to integrated resource management orientation. Wildlife and recretation resource planning have been part of this evolution, which has been stimulated somewhat by recent land management planning-oriented legislation such as the National Forest Management Act and the Federal Land Policy and Management Act.
During the last couple of years, a system for recreation planning within the context of integrated resource planning has emerged. It is called Recreation Opportunity Spectrum (ROS) planning and arose as an old idea was made operational …
