This study focused on the in situ leaf decomposition of Artemisia californica Less. using the litterbag method. Litterbags (10 x 10 cm) were constructed using 2 mm mesh screening material for the top cover to allow microarthropods to pass freely and a . . .

Anthropogenic nitrogen (N) deposition represents a significant input of N into coastal sage scrub (CSS) and chaparral ecosystems of Southern California. Increased N deposition has the potential to alter the decomposition rate of soil organic matter (S . . .

Hookworm infection in humans causes substantial morbidity; however, the relationship between infection and host exercise has not been quantified experimentally for these types of parasites. Human immune response to hookworms is often modeled using lab . . .

Endangered species propagation is an important component of wildlife conservation. Perivitelline membrane (PVM)-bound sperm detection has recently been incorporated into avian breeding programs to assess egg fertility, verify breeding or artificial in . . .

According to sex allocation theory and evolutionarily stable strategy models, several characteristics, including a greater than twofold increase in male fitness, are required for functional androdioecy. Lloydia serotina (Liliaceae ), a morphologically . . .

This research investigates the reproductive biology of the California state threatened plant, Hazardia orcuttii (Asteraceae). The only documented U.S. location of this perennial shrub. is in Encinitas, San Diego County, California. Very little ecologi . . .

Many biologists use passive-infrared motion detectors (PIDs) to monitor the motion or presence of warm-blooded animals in their research. This study determined some of the capabilities of a commercially available PID. Three small-mammal proxies (4.45 . . .

The importance of perennial access to water for invasive plants in arid environments was examined at eighteen sites containing Eucalyptus groves in proximity to a water source within San Diego County between June I stand September 30111, 2009. Diamete . . .

Cortaderia selloana, or pampas grass, is a serious invader of disturbed, coastal and riparian ecosystems in Southern California. The purpose of this study was to determine how the growth and physiology of C. selloana respond to various combinations of . . .

Southern California's geography and expanding population have caused an increasing amount of atmospheric nitrogen (N) deposition into semi-arid shrubland ecosystems. However, the effects of N deposition on semi-arid shrublands of Southern California a . . .
