This book was released on 2004 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Galapagos Islands, located off the coast of Ecuador, have a spatially diverse marine environment suitable for a variety of species with different climatic requirements. A year-long inventory program was carried out in 2000-2001 to provide baseline data on the abundances and distribution of coastal fish and macro-invertebrates. The purposes of this analysis are to use these data to describe the major trends in the community composition of coastal fish and macro-invertebrates and to relate the observed community structure to environmental parameters. A series of Non-metric Multidimensional Scaling (NIMS) ordinations, Multi-Response Permutation Procedures (MRPP) and Indicator Species Analyses (ISA) were performed on the community data. The results are analyzed with respect to major climate zones, upwelling regimes, prevalent benthic community, regional distribution of species, and habitat preferences. The results show that the community of coastal fish and macro-invertebrates in the Galapagos has a considerable degree of structure. Although most environmental variables do not show a strong relationship with individual ordination axes, a clear pattern can be discerned. The species composition of the communities in the warm tropical zone to the north is different from that of the coldest zone of the islands in the west. The community composition of the central and southern zones do not separate as clearly in the ordination space, but the communities belonging to the cool southern region are more similar to those of the tropical zone than to those of the coldest western region. Weaker patterns of community structure are observed when analyzing the data with respect to upwelling regime and community type (algal or coral). When groups of sites are defined with respect to environmental attributes, MRPP shows that there are small differences in species composition between groups, while Indicator Species Analysis yields several strong indicators for each group. The results of the ordination, MRPP tests, and Indicator Species Analysis suggest that the majority of fish and macro-invertebrate species of Galapagos are generalists, found across all environmental gradients; but that there are also significant numbers of more specialized species that occur in only limited regions. In order to properly protect these specialized species, fully protected zones should be established in each of these different regions. This study provides a baseline for future studies of nearshore marine faunistics in Galapagos. Future studies of the community structure of fish and macro-invertebrates in the Galapagos Islands will be able to document changes by comparing their results to those presented here. This information can then be used to help identify causes for changes, whether they are natural or anthropogenic.

Download or read book Darwin s Fishes written by Daniel Pauly and published by Cambridge University Press. This book was released on 2007-08-27 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Darwin's Fishes, Daniel Pauly presents an encyclopaedia of ichthyology, ecology and evolution, based upon everything that Charles Darwin ever wrote about fish. Entries are arranged alphabetically and can be about, for example, a particular fish taxon, an anatomical part, a chemical substance, a scientist, a place, or an evolutionary or ecological concept. The reader can start wherever they like and are then led by a series of cross-references on a fascinating voyage of interconnected entries, each indirectly or directly connected with original writings from Darwin himself. Along the way, the reader is offered interpretation of the historical material put in the context of both Darwin's time and that of contemporary biology and ecology. This book is intended for anyone interested in fishes, the work of Charles Darwin, evolutionary biology and ecology, and natural history in general.

Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

This book was released on 2012-12-05 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this launch of the Galapagos series, this book provides a broad “framing” assessment of the current status of social and ecological systems in the Galapagos Islands, and the feedback that explicitly links people to the environment. It also highlights the challenges to conservation imposed by tourism in the Galapagos Islands and the attendant migration of people from mainland Ecuador to service the burgeoning tourism industry. Further, there is an emphasize on the status of the terrestrial and marine environments that form the very foundation of the deep attraction to the Islands by tourists, residents, scholars, and conservationists.
