From the rear cover: "Algae exhibit the greatest variety of cell motility phenomena in the living world. These range from gliding of filaments in the prokaryotic blue-green algae to the chloroplast movements and cytoplasmic streaming most common in higher plants. In addition cell movement by eukaryotic flagella is the characteristic motile behavior of algal flagellates and most reproductive cells of algae. These motility responses are regulated by light and have attracted much attention from cell biologists and photobiologists interested in the interactions between light, intracellular signals, and the motile machinery. Edited by Michael Melkonian, a leading algal cell biologist, this book brings together for the first time up-to-date information on a broad range of algal cell motility systems. Six-leading researchers have contributed in-depth reviews of the subject, and many illustrations accompany the individual chapters. The book should be of interest to phycologists, cell biologists and photobiologists, to students as well as established researchers." . First Printing of the First Edition. Hardcover.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Algae exhibit the greatest variety of cell motility phenomena in the living world. These range from the peculiar gliding motility of filamentous blue green algae or cyanobacteria to chloroplast movements and cytoplasmic streaming which are most common in higher plants. In addition, cell motility by eukaryotic flagella is the characteristic mode of cell locomotion in algal flagellates and most reproductive cells of algae. Algae use these cell motility systems mainly to orient themselves or their photosynthetic organelles in a suitable light gradient to optimize growth and reproduction. In consequence most of the motility systems are coupled to photoreceptors and are regulated by signal transduction cascades. Algal cell motility has thus attracted consid erable interest also from non-phycologists and some algal motility systems have become models of research in cell and molecular biology. This book summarizes some of the progress that has been made in recent years in the analysis of cell motility phenomena in the algae. Although complete coverage of the subject was not attempted, the six chapters cover all the major types of cell motility systems and the authors provide in depth reviews of gliding motility, chloroplast movements, cytoplasmic streaming, flagellar beat pat terns, mechanisms of flagellar movement and centrin-mediated cell motility.

Hardcover. Condizione: gut. 2. Edition (4. Januar 2012). Mit etwa 50 % der weltweiten Photosyntheseleistung nehmen Algen eine Schlüsselposition an der Basis der Nahrungsketten der Meere und des Süßwassers ein. Trotz ihrer immensen ökologischen Bedeutung sind die Kenntnisse über Algen wenig verbreitet. Das vorliegende Buch erlaubt auch Anfängern ohne Vorkenntnisse einen leichten Einstieg in die faszinierende Welt der Süßwasseralgen. Ein einleitender Teil informiert über die Benutzung des Algenführers; weitere Themen: Was sind Algen? Wo finde ich Algen? Wie sammle und bestimme ich Algen? Die Bedeutung der Algen in der wissenschaftlichen Forschung Kultur von Algen Ein neuartiger Bestimmungsschlüssel erlaubt die Bestimmung einer Gattung in nur zwei Schritten: Zuordnung der Algen zu einer morphologischen Gruppe Bestimmung der Gattung nach grafischen Darstellungen, die sich auf die wesentlichen Merkmale beschränken Im Hauptteil werden die 150 wichtigsten Gattungen auf je einer Doppelseite dargestellt: Eine Textseite mit Angaben zu Artenzahl, Aussehen, Fortpflanzung, Variabilität innerhalb der Gattung, Verwechslungsmöglichkeiten, Ökologie und Vorkommen Eine Bildseite mit mehreren Farbfotografien zur Variabilität der Gattung und Fortpflanzung Erschließung der morphologischen Gruppen über einen Farbschlüssel 110 Themenboxen führen in aktuelle Themen zur Biologie der Algen ein. Anschauliche Grafiken zur Fortpflanzung, Zellteilung, Variabilität und ähnlichen Gattungen ergänzen die Textseiten und Themenboxen. Der Kosmos-Algenführer" ist das Bestimmungsbuch zu den häufigsten Süßwasseralgen Mitteleuropas. Alle behandelten Gattungen werden in Farbfotos vorgestellt. Ein farbiger Bildschlüssel erleichtert die Bestimmung. Unentbehrlich für Mikroskopiker, Biologen und Naturschützer. Hut ab, hier wurde eine echte Lücke in der Bestimmungsliteratur geschlossen, und das in sehr ansprechender Weise. Mir gefällt der schöne Übersichtschlüssel, der auf wenigen Seiten mit sehr klaren Zeichnungen die visuelle Bestimmung der meisten in Deutschland vorkommenden Algengattungen (Süßwasser, ohne Brackwasser wie z.B. Elbe-/Wesermündung etc.) ermöglicht. Der Schlüssel verweist jeweils auf eine Seite mit Farbfotografien und ausführlichem Text. Schon der Ansatz gefällt mir: die Beschränkung auf Gattungen von Algen (also Gruppen naher verwandter Arten) vermeidet "Scheinbestimmungen" von Einzelarten, die einer kritischen Überprüfung sowieso nicht standhalten, da es i.d.R. viele ähnliche, nahe verwandte Arten gibt, die sich genetisch oder über komplexe Merkmale wie Vermehrungstyp unterscheiden. Dieses Risiko der Scheinbestimmung trifft auf viele Klassiker der Mikroorganismenbestimmung zu, wie z.B. "Leben im Wassertropfen". Die Fotos sind meines Erachtens hervorragend. Die Bilder sind mit Interferenzkontrast aufgenommen und die hohe Auflösung des Bildes wird mit einer scheinbaren leichten "Weichheit" der Abbildung erkauft. Das wirkt auf den ersten Blick "unscharf"; mit stärkerer Abblendung des Mikroskopkondensos erscheinen Algen zwar kontrastreicher, aber Zilien und Zellstrukturen würden dafür hinter konktrastreichen Zellumrissen verschwinden. Übrigens sind die Autoren für die Fotos systematisch mit hohem apparativen Aufwand vorgegangen, denn viele einzellige Algen bewegen sich sehr schnell und taumelnd und nur eine spezielle Blitzkonstruktion ermöglichte die Aufnahmen. Nett sind auch die Textboxen, die vieles Wissenswertes zu Süßwasseralgen (Ökologie, Verwandtschaft, Historisches, Anwendungen.) beisteuern. Ein sehr gelungenes Werk für den Mikroskopiker (man benötigt ein Mikroskop, um die Algen zu bestimmen). Sehr gut auch für Mikroskop-Einsteiger geeignet: für Laien sehr anwendbar und wegen der Textboxen sogar unterhaltsam und (für ein Bestimmungsbuch ungewöhnlich) "lesbar", für den Biologen eine interessante, komplette Übersicht der Süßwasseralgengattungen von ausgewiesenen Experten. Anmerkung zum Mikroskopieren, das man ja praktisch parallel zur Benutzung des Buches macht: praktisch alle Arten kann man mit einem halbwegs anständigen Schülermikroskop beobachten, wobei feine Strukturen wie Zilien und Zellorganellen dann je nach optischer Klasse mehr oder weniger gut sichtbar sind.
