Covering the behavior and ecology of the northern fur seal, this book is a model long-term study of marine mammals, one that tests theory through both observation of undisturbed behavior and manipulative experiments on individuals. Here Roger Gentry draws on nearly two decades of research on three different islands to show how behavior among these seals changes with population size, sex ratio, and environment, to explain the behavior of the population beginning with individuals, and to generalize the results to other members of the eared seal family. In so doing, he offers one of the most...

RNA Interference: Challenges and Therapeutic Opportunities provides readers with recent advances in siRNA design, delivery, targeting and methods to minimize siRNA's unwanted effects. Preclinical and clinical use of synthetic siRNAs, the roles of miRNAs in cancer and the promise of extracellular miRNAs for diagnosis are also covered in this meticulous collection, along with novel methods for identifying endogenous siRNAs and the annotation of small RNA transcriptomes. Written for the highly successful Methods in Molecular Biology series, chapters include the kind of detail...

In the past two decades we have seen a surge forward in understanding the genetics and biochemistry underlying many pediatric orthopaedic disorders. A few projects have even progressed into the realm of clinical trials that are primarily aimed at controlling progressive disease. Meanwhile, genomic technology development has outpaced expectations and is enabling gene discovery for disorders that were previously intractable with traditional genetic methods. Included in this latter category are common disorders that display multigenic inheritance, sporadic disorders, and very rare conditions...

Sea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems. The kelp forest ecosystem is crucial for marine organisms and contains coastal erosion. With the concerns about the imperiled status of sea otter populations in California, Aleutian Archipelago and coastal areas of Russia and Japan, the last several years have shown growth of interest culturally and politically in the status and preservation of sea otter...
