Catalog Description

Hours: 54 (27 lecture, 27 laboratory)
Description: Explore and study the "hot" deserts of southern California, such as the Mojave, Sonoran/Colorado, or other arid locations, discovering the unique animals and plants which are adapted to these extreme and beautiful environments. Deserts compared to nearby coastal habitats or the desert ecosystems in Arizona (depending on local conditions). California study sites visited may include Joshua Tree National Park, Mojave Desert, Salton Sea, and Anza-Borrego State Park. Focus on the interdependency between the physical environments and the biological inhabitants that live there.This class requires the ability to hike moderate distances on uneven ground. This class will involve camping in either developed campsites or in undeveloped wilderness areas. (CSU)

          Methods of Evaluation

          • Classroom Discussions
            • Example: To address Course Lecture Objective #3, "Investigate the interactions that local organisms have with the biotic and abiotic factors of their ecosystems", students might take part in a classroom discussion about the major characteristics of representative species of plants and animals occurring in desert or arid ecosystems of southern California and their role in the ecosystem. Students could be evaluated based on participation, accuracy of information, and completeness of information.
          • Projects
            • Example: To address Course Lecture Objective #3, "Investigate the interactions that local organisms have with the biotic and abiotic factors of their ecosystems", students might complete a project, either individually or in groups, that includes researching the major characteristics of a species of plant or animal occurring in desert or arid ecosystems of southern California and its role in the ecosystem, compiling this information in written or graphical form, and sharing this information in an oral classroom presentation. Students could be evaluated based on the completeness of the project, participation in all aspects of the project, accuracy of information presented, and overall quality of the project.
          • Reports
            • Example: To address Course Lab Objective #5, "Create a detailed field journal or summary report documenting the field experience", students might be asked to write a report summarizing the ecosystems visited, geological and hydrological features observed, and species encountered. Students could be evaluated based on accuracy of information, attention to detail, and completeness of summary.
          • Skill Demonstrations
            • Example: To address Course Lab Objective #1, "Demonstrate the use of a taxonomic key or field guide to identify species", students might be asked to use a taxonomic key to correctly identify an organism. Students could be evaluated on the correctness of the answer, technique, and understanding of terminology in the key.

          Methods of Instruction

          • Laboratory
          • Lecture/Discussion

          Lab:

          1. To address Course Lab Objective #1, "Demonstrate the use of a taxonomic key or field guide to identify species", the instructor might lead the class in a demonstration of the use of a dichotomous key for a known specimen, and then guide students as they attempt the identification of an unknown specimen.
          2. To address Course Lab Objective "2, "Identify geological and hydrological features that impact the formation and function of communities of desert and arid ecosystems of southern California", the instructor might point out such key features in the field, making comparisons to other such features observed in the field or described in the classroom. Students will then make and record their own observations and comparisons.

          Lecture:

          1. To satisfy Course Lecture Objective #4, "Explain the role that geology plays in the formation and delineation of communities of desert and arid ecosystems of southern California", the instructor might present a lecture (supplemented by images and/or video) that explains the geological history of the region (e.g. geologic uplift, tectonic plate movements, erosion, etc.) and how it has influenced the development of soils and species assemblages. Students will then make and record their own observations of geological features.
          2. To satisfy Course Lecture Objective #5, "Analyze the past and present effects that humans have on desert and arid ecosystems of southern California", the instructor might lead an in-class discussion about the historical impacts of humans on the region (e.g. mining, water diversion, recreation, conservation, etc.).

          Typical Out of Class Assignments

          Reading Assignments

          1. To address Course Lecture Objective #1, students might be asked to read an article that describes the effects of desertification on local populations of plants and animals and then apply this knowledge to descriptions of observations in the field. 2. To address Course Lecture Objective #3 and Course Lab Objective #3, students might be asked to review life history information for a species that occurs in desert and arid ecosystems of southern California that is available in a field guide, handout, or a natural resource agency website and be prepared to discuss this in class.

          Writing, Problem Solving or Performance

          1. To address Course Lecture Objective #4 and Course Lab Objective #2, students might be asked to write and/or prepare a short oral presentation about a geologic or hydrologic feature occurring in desert or arid ecosystems of southern California. 2. To address Course Lab Objective #5, students might be asked to document their observations in the field in a journal, using any combination of text, sketches, photos, and/or other media.
