Download or read book Benthic Diatoms from Mediterranean Coasts written by Irene Álvarez-Blanco and published by . This book was released on 2014-01-17 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a taxonomic study of benthic diatoms collected from coastal rocks in seven northern Mediterranean sites (Italy, Spain, Greece, Turkey) in spring of 2010. An iconographic catalogue of high-quality SEM and light microscopic images, plus detailed taxonomic, nomenclatural and bibliographic information, are provided as a practical reference for further taxonomic and floristic studies on 91 plates. 120 representative diatom taxa, among them several poorly known species, selected from 23 samples, are described in terms of their abundance. The authors provide detailed information on the type material of each diatom species, a list of synonyms, a comparison of morphometric data provided in the literature (in tables) and a series of iconographic SEM-images which illustrate the taxon’s morphological variability, plus an exhaustive list of references. Nomenclature, taxonomy and systematic position of the described taxa are updated. Eight taxa are described as new to science and another seven are nomenclaturally recombined. Eight taxa are new records for the Mediterranean Sea and for five taxa Scanning Electron Microscope (SEM) images are presented for the first time. An exhaustive reference list and indices of taxa conclude this volume and make it a valuable source of information for biologists working on benthic diatoms in general, not only of the Mediterranean region.

This book was released on 2016 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amb cinc capítols, la tesi doctoral combina l'estudi dels hàbitats presents, passats i futurs del Delta de l'Ebre, un dels ecosistemes d'aiguamolls més gran del Mediterrani occidental. S'han aplicat diferents aproximacions per cadascuna de les tres escales temporals: i) en el present, la utilitat de diatomees i foraminífers bentònics com a indicadors ecològics dels hàbitats del Delta de l'Ebre, ii) en el passat, l'ús de les comunitats de foraminífers preservades en el sediment per reconstruir els canvis associats a factors naturals i humans, i iii) en el futur, la distribució potencial dels hàbitats assumint un escenari de nul·la intervenció humana. Els resultats posen en evidència la capacitat de cadascun dels dos grups d'indicadors per caracteritzar de forma diferent tot el rang d'hàbitats deltaics, indicant que aquest coneixement pot ser útil en el context de futurs impactes del canvi climàtic (és a dir increment del nivell del mar i retrocés de la costa), ja que els models de distribució dels hàbitats són sensibles a variables eco-geogràfiques com l'elevació i distància a la costa. Per cadascun dels hàbitats identificats, s'han determinat diferents espècies indicadores de diatomees i foraminífers. Algunes d'aquestes espècies podrien detectar canvis primerencs en les comunitats degut a que els hàbitats estan afectats per múltiples factors d'estrès natural i antropogènic. Els resultats també mostren que quan es combinen les comunitats de foraminífers bentònics que habiten en la plana deltaica i els hàbitats marins adjacents, s'obté una nova eina per la reconstrucció paleoambiental en deltes. En el cas del Delta de l'Ebre, el registre de foraminífers de testimonis profunds datats amb carboni-14 va permetre rebutjar la hipòtesi que el Delta era un estuari abans de l'època dels Romans (fa uns 2000 anys). A una escala temporal inferior (10-100 anys), les comunitats de foraminífers indiquen canvis significatius en el tipus d'hàbitat com a resultat de l'introducció del cultiu intensiu de l'arròs. Aquests resultats aporten informació valuosa sobre les condicions de referència dels hàbitats del Delta de l'Ebre per tal d'informar futurs plans de restauració i monitoreig ambiental.

Available in PDF, EPUB and Kindle. Book excerpt: Intermittent Rivers and Ephemeral Streams: Ecology and Management takes an internationally broad approach, seeking to compare and contrast findings across multiple continents, climates, flow regimes, and land uses to provide a complete and integrated perspective on the ecology of these ecosystems. Coupled with this, users will find a discussion of management approaches applicable in different regions that are illustrated with relevant case studies. In a readable and technically accurate style, the book utilizes logically framed chapters authored by experts in the field, allowing managers and policymakers to readily grasp ecological concepts and their application to specific situations. - Provides up-to-date reviews of research findings and management strategies using international examples - Explores themes and parallels across diverse sub-disciplines in ecology and water resource management utilizing a multidisciplinary and integrative approach - Reveals the relevance of this scientific understanding to managers and policymakers

Book excerpt: The aim of this new book series (Diatoms: Biology and Applications) is to provide a comprehensive and reliable source of information on diatom biology and applications. The first book of the series, Diatoms Fundamentals & Applications, is wide ranging, starting with the contributions of amateurs and the beauty of diatoms, to details of how their shells are made, how they bend light to their advantage and ours, and major aspects of their biochemistry (photosynthesis and iron metabolism). The book then delves into the ecology of diatoms living in a wide range of habitats, and look at those few that can kill or harm us. The book concludes with a wide range of applications of diatoms, in forensics, manufacturing, medicine, biofuel and agriculture. The contributors are leading international experts on diatoms. This book is for a wide audience researchers, academics, students, and teachers of biology and related disciplines, written to both act as an introduction to diatoms and to present some of the most advanced research on them.
