Competition And Spacing Patterns Of Shrubs In The Mojave And Sonoran Deserts, Donald Lundahl Phillips
Competition And Spacing Patterns Of Shrubs In The Mojave And Sonoran Deserts, Donald Lundahl Phillips
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Spacing patterns of shrubs were studied at a series of sites in the Mojave and Sonoran Deserts. There were significant numbers of occurrences of both aggregation and regularity in dispersion of individuals. These may be due to vegetative reproduction or environmental heterogeneity, and competition between plants, respectively. Different size classes of shrubs tended to follow the trend of aggregated → random → regular with increasing size. This suggests the increasing importance of competition as the plants grow. Further evidence of competition between plants was provided by the correlations of plant size with the distance to their neighbors. Root systems were …

Fisheries Report No 32 - The Wildlife Of The Proposed Wandana Nature Reserve, Near Yuna, Western Australia, A. A. Burbidge, P. J. Fuller, A. Mccusker
Fisheries Research Reports
Following a Cabinet endorsed recommendation by the Environmental Protection Authority in 1976 an area of vacant Crown land (the Wandana Area) north-east of Yuna, Western Australia, was examined during March and September, 1977.
The geology, soils and vegetation of the area are described and annotated lists of mammals, birds, reptiles and amphibians are presented. The area lies near or on the boundary of the South- Western and Eremaean Botanical Provinces and vegetation formations typical of both occur. The vertebrate fauna is a mixture of South-Western and Eyrean species and is especially rich in reptiles, 41 species being recorded. Comparisons between …
