This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. 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 Environmental Condition of the Mediterranean Sea written by F.B. de Walle and published by Springer Science & Business Media. This book was released on 1993-08-31 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Environmental Program for the Mediterranean (EPM) assesses the nature and the extent of the environmental problems in the Mediterranean Basin. It leads to recommendations for short- to medium-term actions. Policies, institutional measures, technical assistance and investment project proposals are necessary to ameliorate such problems. The EPM emphasizes the economic and financial implications of environmental protection. It suggests ways in which the countries of the region can achieve the high-priority environmental investments that are recommended. The case is made for greater efforts from the international aid community to assist the Mediterranean countries in this endeavor. The EPM is a common initiative launched in 1988 by the European Investment Bank and by the World Bank. The World Bank has economic development as its main objective. The Bank has lent for development projects since 1946, primarily in the developing countries of the Third World. The EIB's main task, under Article 130 of the Treaty of Rome, is to contribute to the balanced development of the European Community, another of its priorities is the protection of the environment. The Netherlands Organization for Applied Scientific Research (TNO) derives its legal status from an Act of Parliament of 1930 on applied scientific research in the Netherlands. It is a fully independent R & D organization and currently has a staff of about 5,100 and a turnover of more than 370 million U.S. dollars a year. Studies by TNO are carried out in a number of institutes and laboratories located throughout the Netherlands. TNO's primary task is to support technological innovation in trade and industry, government agencies and community groups. TNO also assists clients and sponsors in solving problems. It conducts consultancy and transfers knowledge and know-how to individual companies and sector groups. Know-how is obtained from TNO's own research or is generated through collaboration with universities and third parties. The present study is sponsored by the European Investment Bank in the framework of the EPM. The TNO report gives an overview of the environmental condition of the Mediterranean, especially that of EC Mediterranean countries. It also estimates the environmental investment requirements for sewage treatment plants, river basin management, port reception facilities other environmental protection measures.

Download or read book Marine Macroecology written by Jon D. Witman and published by University of Chicago Press. This book was released on 2009-10-15 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pioneered in the late 1980s, the concept of macroecology—a framework for studying ecological communities with a focus on patterns and processes—revolutionized the field. Although this approach has been applied mainly to terrestrial ecosystems, there is increasing interest in quantifying macroecological patterns in the sea and understanding the processes that generate them. Taking stock of the current work in the field and advocating a research agenda for the decades ahead, Marine Macroecology draws together insights and approaches from a diverse group of scientists to show how marine ecology can benefit from the adoption of macroecological approaches. Divided into three parts, Marine Macroecology first provides an overview of marine diversity patterns and offers case studies of specific habitats and taxonomic groups. In the second part, contributors focus on process-based explanations for marine ecological patterns. The third part presents new approaches to understanding processes driving the macroecolgical patterns in the sea. Uniting unique insights from different perspectives with the common goal of identifying and understanding large-scale biodiversity patterns, Marine Macroecology will inspire the next wave of marine ecologists to approach their research from a macroecological perspective.

Download or read book The Hawaiian Spinner Dolphin written by Kenneth S. Norris and published by Univ of California Press. This book was released on 1994-08-30 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty years in the making by a distinguished dolphin expert and his associates, The Hawaiian Spinner Dolphin is the first comprehensive scientific natural history of a dolphin species ever written. From their research camp at Kealakeakua Bay in Hawaii, these scientists followed a population of wild spinner dolphins by radiotracking their movements and, with the use of a windowed underwater vessel, observing the details of their underwater social life. The authors begin with a description of the spinner dolphin species, its morphology and systematics, and then examine the ocean environment, the organization of dolphin populations, and the way this school-based society of mammals uses shorelines for rest and instruction of the young. The dolphins' reproductive cycle, their vision, vocalization, hearing, breathing, and feeding, and the integration of the school are carefully analyzed. The authors conclude with a comprehensive evolutionary analysis of this marine cultural system, with its behavioral flexibility and high levels of cooperation. This absorbing book is the richest source available of new scientific insights about the lives of wild dophins and how their societies evolved at sea.

Download or read book Social Predation written by Guy Beauchamp and published by Elsevier. This book was released on 2013-12-07 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The classic literature on predation dealt almost exclusively with solitary predators and their prey. Going back to Lotka-Volterra and optimal foraging theory, the theory about predation, including predator-prey population dynamics, was developed for solitary species. Various consequences of sociality for predators have been considered only recently. Similarly, while it was long recognized that prey species can benefit from living in groups, research on the adaptive value of sociality for prey species mostly emerged in the 1970s. The main theme of this book is the various ways that predators and prey may benefit from living in groups. The first part focusses on predators and explores how group membership influences predation success rate, from searching to subduing prey. The second part focusses on how prey in groups can detect and escape predators. The final section explores group size and composition and how individuals respond over evolutionary times to the challenges posed by chasing or being chased by animals in groups. This book will help the reader understand current issues in social predation theory and provide a synthesis of the literature across a broad range of animal taxa. - Includes the whole taxonomical range rather than limiting it to a select few - Features in-depth analysis that allows a better understanding of many subtleties surrounding the issues related to social predation - Presents both models and empirical results while covering the extensive predator and prey literature - Contains extensive illustrations and separate boxes that cover more technical features, i.e., to present models and review results

Download or read book Pinnipeds and El Ni o written by Fritz Trillmich and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: El Niño is a meteorological and oceanographic phenomenon, which occurs at irregular intervals in the eastern tropical Pacific. Its most obvious characteristic is the warming of surface waters, which causes enormous disturbances of the marine environment. A severe Niño may also affect continental systems worldwide. This book gathers in a comprehensive way the information available on the effects of the exceptionally strong 1982-83 Niño on a group of marine mammals, the pinnipeds. It presents an analysis of the effects of environmental stress on the populations of top predators. Data and interpretations are based on a most unusual collection of long-term studies of pinniped population dynamics, behavior and ecology which spanned the El Niño event. The responses of pinniped populations to the El Niño disturbance of the marine ecosystem also has important implications for the management and conservation of marine mammal populations.
