Plant Demography and Chaparral Management in Southern California 1
نویسنده
چکیده
A landscape may be viewed as a mosaic of patches. The state of the ecosystem can be defined by the abundance of species measured in some appropriate way. Within each patch the species populations change as the result of mortality and establishment. Through time, species populations are disappearing in some patches and dispersing to and becoming established in others where they are absent; the general case of "island biogeography".

Optimum pixel size for hyperspectral studies of ecosystem function in southern California chaparral and grassland
Hyperspectral remotely sensed data are useful for studying ecosystem processes and patterns. However, spatial characterization of such remotely sensed images is needed to optimize sampling procedures and address scaling issues. We have investigated spatial scaling in ground-based and airborne hyperspectral data for canopyto watershed-level ecosystem studies of southern California chaparral and ...
متن کاملPostburn Insect Fauna in Southern California Chaparral1
Professor of Biological Sciences, California State Polytechnic University, Pomona, California 91768. Abstract: Extremely little is known about succession of insects in postfire chaparral. This 4-year postfire study in the San Gabriel Mountains of southern California showed that pollen-nectar feeders and predatory insects can be very abundant beginning the first spring after a burn. Annual plant...
متن کاملRemote Sensing Analysis of Vegetation Recovery following Short-Interval Fires in Southern California Shrublands
Increased fire frequency has been shown to promote alien plant invasions in the western United States, resulting in persistent vegetation type change. Short interval fires are widely considered to be detrimental to reestablishment of shrub species in southern California chaparral, facilitating the invasion of exotic annuals and producing "type conversion". However, supporting evidence for type ...
متن کاملPersistence of 2,4-D and 2,4,5-T in chaparral soil and vegetation.
The behavior of 2,4-D and 2,4,5-T has been widely studied in the cool moist forests of the Pacific Northwest (NORRIS 1971). Little data are available, however, for the unique conditions in arid southern California, where the two compounds are used for maintenance of fuelbreaks in chaparral vegetation. Reported here is a study to determine the movement and persistence of 2,4-D and 2,4,5-T in soi...
متن کاملProductivity and Nutrient Cycling in the Early Postburn Chaparral Species Lotus scoparius1
2 Postdoctoral Researcher, University of California, Irvine, Calif. Abstract: The frequent fires in southern California have a pronounced influence on many aspects of chaparral shrub communities, particularly nutrient relationships. Nutrient accumulation, and productivity were studied for the post fire species Lotus scoparius. This stand of Lotus scoparius was approaching maximum biomass yet th...
