Safeguarding diversity: challenges in developing a genome resource bank for the California sea otter
Article Abstract:
Genome resource banks (GRBs) for the California sea otter population can safeguard the existing genetic diversity against disease epidemics and environmental disasters, such as major oil spills. The advantages of GRBs depend on the proper use of stored genetic material through assisted reproductive techniques such as artificial insemination, in vitro fertilization and transfer of embryo. Studies on male and female sea otter reproduction and endocrinology, and cryopreservation protocols are necessary to enhance the development of GRBs.

Monitoring the status of the wild sea otter population: field studies and techniques
Article Abstract:
The analyses of the physiological, population and behavioral parameters allows the monitoring of the population status of California wild sea otters. Population density can be calculated from population census data and measure of abundance. The monitoring of the animal and analysis of the reproductive tracts provides information on reproduction. The blood analysis and lymphocyte proliferation assay give estimate of physiological parameters. The activity budget and food habits indicate the abundance of food in their habitat.

A complex chromosome rearrangement in the karyotype of a wild-caught male sea otter
Article Abstract:
Chromosomal abnormalities are seen in the karyotype of the California male sea otters in the Sea World sea otter breeding colony. Three pairs of male chromosomes; b5, c10 and c13; show rearrangements, as compared to the female chromosomes. The rearrangements are seen in the leucocyte and fibroblast cells. The existence of chromosomal differences in the male karyotype are important contributors to the reproductive problems in the breeding colony.
