Download or read book Marine Ecosystems and Climate Variation written by Nils Chr. Stenseth and published by OUP Oxford. This book was released on 2005-05-19 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research level text focuses on the influence of climate variability on the marine ecosystems of the North Atlantic. The ecological impact of climate variability on population dynamics is addressed at the full range of trophic levels, from phytoplankton through zooplankton and fish to marine birds. Climate effects on biodiversity and community structure are also examined. 40 scientists from around the world synthesise what is currently known about how climate affects the ecological systems of the North Atlantic and then place these insights within a broader ecological perspective. Many of the general features of the North Atlantic region are also seen in other marine ecosystems as well as terrestrial and freshwater systems. The final section of the book makes these generalities more explicit, so as to stimulate communication and promote co-operation amongst researchers who may previously have worked in semi-isolation. The book comprises 5 main sections: background (general introduction, atmospheric and ocean climate of the North Atlantic, and modelling methodology), plankton populations (phytoplankton and zooplankton), fish and seabird populations, community ecology (phytoplankton, benthos and fish), and the final section consisting of six commentaries from scientists working in areas outside the North Atlantic marine sector. In order to enhance integration, a series of introductions link chapters and sections. Throughout the book, numerous examples highlight different aspects of ecology-climate interactions. They document recent progress and illustrate the challenges of trying to understand ecological processes and patterns in the light of climate variations.

Available in PDF, EPUB and Kindle. Book excerpt: The term "zooplankton" describes the community of floating, often microscopic, animals that inhabit aquatic environments. Being near the base of the food chain, they serve as food for larger animals, such as fish. The ICES (International Council for the Exploration of the Sea) Zooplankton Methodology Manual provides comprehensive coverage of modern techniques in zooplankton ecology written by a group of international experts. Chapters include sampling, acoustic and optical methods, estimation of feeding, growth, reproduction and metabolism, and up-to-date treatment of population genetics and modeling. This book will be a key reference work for marine scientists throughout the world. Sampling and experimental design Collecting zooplankton Techniques for assessing biomass and abundance Protozooplankton enumeration and biomass estimation New optical and acoustic techniques for estimating zooplankton biomass and abundance Methods for measuring zooplankton feeding, growth, reproduction and metabolism Population genetic analysis of zooplankton Modelling zooplankton dynamics This unique and comprehensive reference work will be essential reading for marine and freshwater research scientists and graduates entering the field.
Download or read book Molecular Approaches to the Study of the Ocean written by K.E. Cooksey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine biological science is now studied at the molecular level and although research scientists depend on information gained using molecular techniques, there is no book explaining the philosophy of this approach. Molecular Approaches to the Study of the Ocean introduces the reasons why molecular technology is such a powerful tool in the study of the oceans, describing the types of techniques that can be used, why they are useful and gives examples of their application. Molecular biological techniques allow phylogenetic relationships to be explored in a manner that no macroscopic method can; although the book deals with organisms near the base of the marine food web, the ideas can be used in studies of macroorganisms as well as those in freshwater environments.

Download or read book The Functioning of Ecosystems written by Mahamane Ali and published by BoD – Books on Demand. This book was released on 2012-04-27 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ecosystems present a great diversity worldwide and use various functionalities according to ecologic regions. In this new context of variability and climatic changes, these ecosystems undergo notable modifications amplified by domestic uses of which it was subjected to. Indeed the ecosystems render diverse services to humanity from their composition and structure but the tolerable levels are unknown. The preservation of these ecosystemic services needs a clear understanding of their complexity. The role of the research is not only to characterise the ecosystems but also to clearly define the tolerable usage levels. Their characterisation proves to be important not only for the local populations that use it but also for the conservation of biodiversity. Hence, the measurement, management and protection of ecosystems need innovative and diverse methods. For all these reasons, the aim of this book is to bring out a general view on the biogeochemical cycles, the ecological imprints, the mathematical models and theories applicable to many situations.
Download or read book Metabarcoding Analysis of Prey Composition of the Copepod Calanus Finmarchicus in Regions of the North Atlantic Ocean written by Heidi Yeh and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The copepod Calanus finmarchicus occupies a pivotal position in the pelagic food web of the North Atlantic Ocean. Prey choice and predator-prey dynamics at this trophic level can influence energy transfer through the ecosystem. To examine the copepod prey composition and test the hypothesis that C. finmarchicus exhibit spatial variation in diet across four basins of the North Atlantic, this study used metabarcoding analysis (high throughput sequencing of orthologous gene regions) to analyze the gut contents of C. finmarchicus. Zooplankton net samples were collected during a 2013 cruise of the R/V GO Sars in the Norwegian, Icelandic, Irminger, and Labrador basins. The V4 hypervariable region of 18S ribosomal RNA (rRNA) was used to detect a broad spectrum of potential prey items based on DNA extracted from gut contents of C. finmarchicus. Using "universal" eukaryotic primers necessitated the development of methods to limit the signal of copepod DNA relative to the DNA of its prey. Although limited in taxonomic resolution, the results provide evidence of patterns of time / space variation of major diet components of C. finmarchicus across the North Atlantic. Across the dataset, the following taxonomic groups were found in order of decreasing abundance: diatoms, dinoflagellates, cnidarians, ctenophores, apicomplexa, ciliates, nematodes, and others. Strong evidence of likely symbionts and parasites in the gut of C. finmarchicus was found. This study provides a foundation for future efforts that may utilize primers that target narrower taxonomic groups, and thereby expand the study of diet and potential prey selectivity of C. finmarchicus.

Available in PDF, EPUB and Kindle. Book excerpt: One species dominates the zooplankton biomass throughout the north-west Atlantic in spring & summer, the copepod Calanus finmarchicus. This species has a critical role in the transfer of primary production to higher trophic levels and the flux of faecal material to the sediments. This report summarizes a workshop that included presentations on the challenge of a north Atlantic basin-scale study of C. finmarchicus, the current state of knowledge of its distribution & ecology in the north-west Atlantic, the physical oceanography of the region, and potential modelling approaches, both biological & hydrodynamic. Three working groups identified questions & major knowledge gaps with regard to describing & modelling the basin-scale population dynamics of C. finmarchicus across the north Atlantic. The results of these working groups were reviewed in plenary session, and three different groups were formed to discuss elements of an overall research plan that would address the important questions.
