Exciting Opportunity for Undergraduate Students: Participate in research in Baja California with Mexican collaborators and students for the purpose of studying biodiversity in the region. Prior to the fieldwork, students would be given several readings to discuss on the region and its biodiversity. Students would accompany Dr. Therese Markow and several other US researchers in field vehicles, to Ensenada to meet up with Mexican scientists and then continue down the Baja California peninsula to La Paz. Terrestrial arthropods and intertidal marine invertebrates would be collected from localities along the way. Students would learn field sampling techniques, GPS, identification and preservation approaches, and databasing approaches. Daytime activities would include collecting at various sites en route to La Paz, and in the evenings, sorting, identifying and data basing specimens along with discussions of readings. Students may participate for credit in one or more segments of the activity. Those who could only attend only part of the trip would be flown from La Paz to Tucson or Tucson to La Paz approximately half way through the trip. Once back in the US, students would have the opportunity to perform research projects, for additional credit, on some of the collected material. For example, students with an ecological orientation might be interested in calculating diversity indices for different areas. Students interested in evolution could use PCR-based DNA sequencing to examine phylogenetic relationships among given species from different parts of their range. Students would sign up for from 1-4 credits, depending upon their level of participation. Screening applications will be competitive. Only serious, mature students will be accepted for the project. All expenses will be covered for students selected to participate. Students interested in this opportunity should contact Dr. Terry Markow directly at tmarkow@public.arl.arizona.edu.
