The Role Of Vegetation Architecture In Determining Spider Community Organization, Cynthia L. Hatley
The Role Of Vegetation Architecture In Determining Spider Community Organization, Cynthia L. Hatley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The relationships between vegetation architecture and spider community attributes were examined in a big sage (Artemisia tridentata) community. Spiders were separated into guilds using similarities of species' hunting behavior. Shrub architecture was experimentally manipulated in the field by either clipping 50% of a shrub's foliage to decrease foliage density or tying together a shrub's branches to increase foliage density.
Temporal patterns of spider species density, diversity (H') and evenness (J') showed midsummer peaks in both 1974 and 1975. Seasonal spider guild trends reflected the temporal prominence of a member species or genus. These temporally abundant species appeared to …

Bulletins
The research described in this report was a further effort to determine the potential of woody plants and forest waste not normally used commercially as a source of wood pulp. The results of previous studies of this subject have been reported in several technical journals and as LSA Experiment Station Bulletins over a period of several years.
It was concluded that the only feasible way of harvesting this type of material for pulping would be as a whole plant. The small size and large proportions of bark and small branches would preclude any kind of barkwood separation process. If species …
