![]() If the mice do not display appropriate behavior, we will give them the necessary experience to select the right types of foods and identify and escape predators in a safe environment. Before we release offspring born at the facility to repopulate reserves in the wild, we will conduct similar behavioral assessments. When we brought the first founder Pacific pocket mice into the facility, we measured these behaviors in order to generate a baseline for normal behavior. It is important that they have species-appropriate behaviors in order to successfully avoid predators and forage for the right types of food. We need to ensure that offspring born at the facility will be able to fend for themselves when, together with our partners, we eventually release them back into the wild. So far, we have more than doubled the number of mice at the facility with successful breeding of founder individuals and their offspring. Here, our Recovery Ecology and Conservation Genetics researchers are studying pocket mouse behavior, ecology, stress, and genetic variation to ensure that we successfully produce the most fit offspring for release and learn as much as we can about them along the way. They then use a genetic code chart, to determine the amino acids encoded by a sequence of the Mc1r gene in different mouse populations. The activity begins with students reading a magazine article and watching the film. Instead, we established the Pocket Mouse Conservation Breeding Facility at the San Diego Zoo Safari Park in 2012. Students analyze genetic sequence data and draw conclusions about the evolution of coat-color phenotypes in the rock pocket mouse. Given the small number of Pacific pocket mice remaining in the wild, a translocation program to populate areas of former habitat was deemed to be too risky. Unfortunately, due to habitat loss there are only three small populations remaining, one on Dana Point and two in military training areas on Marine Corps Base Camp Pendleton. ![]() The specifics of the model are designed on the basis of an. For 20 years, they were actually thought to be extinct until a tiny remnant population was rediscovered in 1994 at Dana Point headlands. The genetics is modeled on the basis of the research on the rock pocket mice populations. Students begin by watching the film and reviewing the basic principles of the Hardy-Weinberg theorem. Students apply the Hardy-Weinberg equation to real data collected on rock pocket mouse populations. Pacific pocket mice used to be found from Los Angeles all the way to the Mexican border at the southern edge of San Diego County. This activity reinforces concepts of variation and natural selection covered in the short film Natural Selection and Adaptation. Threats to Survival: Habitat loss and fragmentation The allele for dark-colored fur ( D) is dominant to the allele for light-colored fur ( d). For simplicity, we will work with two alleles at one gene. That’s why there is a range of fur color from very dark to light. Instructors who search specifically for OERs may miss a rich body of content freely available to educators and students alike.Conservation Status: US Fish and Wildlife Service - Endangered In rock pocket mice, several genes code for fur color. BioInteractive materials are created specifically for educational use, in accord with HHMI’s mission however, the copyrights held by HHMI, and their contracted partners do not permit changing and republishing the content. Carroll says that mutations occur randomly. Mutations are a source of genetic variation. This leads to increased production of eumelanin, which results in the dark color. The amino acid changes in the MC1R protein may change the structure and function of the protein.

OERs and other free materials eliminate a major barrier to student learning: cost. With an Internet connection and a computing device, students can utilize OERs anytime-anywhere as primary or supplementary resources for learning. Open educational resources (OERs) are a recent trend in higher education.
