The Santa Monica Mountains of southern California are located in a Mediterranean-type climate region which experiences reoccurring wildfires due to summer drought and Santa Ana winds. Chaparral vegetation, which consists mostly of evergreen, sclerophyllous shrubs, dominates the landscape. Species of chaparral shrubs have evolved three different life history types in response to fire – those that sprout after fire but do not germinate seeds (obligate sprouters = OS), those that do not sprout after fire but reestablish by seed germination (non-sprouters = NS), and those that both sprout and germinate seeds after fire (facultative sprouters = FS). There are two …

How Do Prey Refuges Affect Predator-Prey Interactions?, Justin Vendettuoli
Senior Honors Projects
While it is well known that predators eat their prey, prey that avoid predation risk can also incur substantial fitness costs through risk-induced changes in survival and reproduction, growth, and morphology. Changes in prey that occur without the predator physically consuming the prey are referred to as ‘non-consumptive effects’. One way to reduce the risk of predation is to use a refuge. While refuge use may reduce predation risk, however, it may also be costly to the prey. These costs may include within-refuge competition for resources, which can alter prey population dynamics, coexistence, and metapopulation dynamics. While these costs may …
