Comparison Of Post-Fire Growth Rates Between Elymus Condensatus And Yucca Whipplei In Coastal Chaparral, Jae K. Chung, Andrew J. Ishibashi, Francisco B. Sapigao
Comparison Of Post-Fire Growth Rates Between Elymus Condensatus And Yucca Whipplei In Coastal Chaparral, Jae K. Chung, Andrew J. Ishibashi, Francisco B. Sapigao

The two monocot species, Yucca whippelei and Elymus condensata chosen for this study are two co-occurring species on the Pepperdine campus. We chose 6 samples of each species and looked at parameters that would allow us to compare their post fire growth rates. These parameters included leaf area index, internal CO2 levels, transpiration rate, and photosynthetic rate. We used the Students T-test on the means of each parameter and found significant differences in leaf area index, internal CO2 levels, and transpiration rate. All of these were greater in the Yucca except for the leaf area index. We concluded that, because …
Growth Sequence Of Post-Fire Chaparral Resprouts In California’S Santa Monica Mountains, Iolana N. Kaneakua, Kelly L. Reynolds, Luke S. Walsh
Growth Sequence Of Post-Fire Chaparral Resprouts In California’S Santa Monica Mountains, Iolana N. Kaneakua, Kelly L. Reynolds, Luke S. Walsh
Featured Research
The post-fire resprout succession of California Chaparral was surveyed in Corral Canyon of the Santa Monica Mountains. The primary objective of this investigation was to determine the sequence of Chaparral post-fire resprouts and possible correlations to the life histories of those species. Over a three month period, four designated study sites were visited every two weeks, surveying the number of adults, the number of resprouts and the height of the resprouts. It was found that both the facultative and the obligate typed species were successful in post-fire resprout. Facultative species were the first to resprout and obligate species displayed the …
Physiological Performance In Full-Sun Vs. Shaded Post-Fire Malosma Laurina Seedlings, Lindsey A. Murphy, David C. Valencia, Catherine D. Drummond
Physiological Performance In Full-Sun Vs. Shaded Post-Fire Malosma Laurina Seedlings, Lindsey A. Murphy, David C. Valencia, Catherine D. Drummond
Featured Research
Post-fire Malosma laurina regenerates both by resprouting and by disseminating seeds. The objective of this study is to assess seedling performance either in full-sunlight or in artificially shaded treatments. By identifying under which conditions Malosma laurina seedlings grow more effectively, one can predict where post-fire M. laurina seedling communities will thrive. The methodology employed throughout this experiment began by covering existing seedlings with shade cloth held by wooden stakes. These treatments were adjacent to full-sun environments; each of which contained at least two Malosma laurina seedlings. Six experimental sites were set up, and the seedlings in question were monitored for …
