Book excerpt: In this study the molecular ecology and fitness of two Delphinidae species, the striped dolphin (Stenella coeruleoalba) and the common dolphin (Delphinus delphis), were investigated in the Mediterranean Sea and Atlantic Ocean. This thesis provides a comparative assessment of the striped and the common dolphin, using molecular methods regarding the genomic diversity and parasite resistance. The striped and the common dolphin have a world-wide distribution, inhabiting pelagic waters and differ with respect to population structure within the study area. The aim is to reveal different patterns of genetic diversity and fitness in the species that shows greater populations structure. In order to test this, my analyses structure was a) to analyse the population structure of the striped dolphin in the Mediterranean Sea and Atlantic Ocean and compare structuring patterns with previous published studies, b) to examine the heterozygosity fitness correlation for both species, using neutral and non-neutral markers and specific parasites that are important of animal?s health. In this context this study tests that local populations show stronger relationship between genetic diversity and fitness. This study suggested that different methods regarding to power and studied subareas show a fine-scale structure beyond that reported previously in striped dolphin populations. A key new finding is the structuring pattern in the Atlantic Ocean, where populations from Scotland and the Biscay Gulf were isolated from the one in Ireland. Also, the Ionian Sea samples grouped with the western Mediterranean, which could either be an effect of the small sample size from the Ionian Sea, or reflect a boundary closer to Greece, dividing the basins of the Mediterranean for this species. In this study I found differences between the two hosts with respect their genetic diversity and parasite loads for both nuclear and functional loci. I also found that evidence for a heterozygosity fitness correlation was strongest for females, and this was true both for the correlation with genomic diversity as assessed using neutral markers, and for the functional immune system gene. This observable association suggests that parasites may act as an energetic stress, and may reflect the non-identical pathogenesis of parasites and their ability to inflict damage through the hormone profiles. Results illustrate potentially important interactions between genetic drift and selection, and provide specific information that will be valuable towards the conservation and management of diversity in these species.

Download or read book Small Cetaceans of Japan written by Toshio Kasuya and published by CRC Press. This book was released on 2017-05-08 with total page 809 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes and analyzes the biology, ecology, exploitation and management of small cetaceans in Japan. It describes the various types of cetacean fisheries in Japan and their historical development, the life histories and ecologies of the main species involved, and the history and problems of conservation and management. The data show that in some cases the number of small cetaceans harvested exceed sustainable limits and have led to depletion of populations. The book provides a case study of what can go wrong when the needs of industry and conservation collide. The descriptions of life history and ecology are relevant to issues of conservation and management, not just for cetaceans, but for all fisheries around the world.

Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals comprise some of the most highly adapted mammals, many with unbelievable diving capabilities, high intelligence and complex social behaviour, and some with brains larger than that of humans. Many possess echolocating and communication skills that we are only beginning to understand. This work brings together a group of experts focused upon cell and molecular biology of aquatic mammals. Methods currently being used to explore marine mammal biology are discussed, such as genetic tracing of subpopulations of whales and seals by DNA fingerprinting, use of immune system molecular markers, cell culture and ELISA techniques, and electron microscopy.
