Algal blooms have become a major problem whilst cases of gastroenteritis and liver cancer have increased dramatically over the last decades. To evaluate the potential health threat, the phytoplankton community in the reservoir was investigated. Inorganic nutrient (2.4-3.0 mg P l-1 and 1.4-3.2 mg N l -1) and conductivity (1433-368 mS cm-1) as well as phytoplankton biomass concentrations (0.8-7.6 mgl-1) were very high. Primary production had increased significantly since 1979, suggesting that the eutrophication problem has increased. Microcystis dominated the phytoplankton community with a low biodiversity (0.92 bits ind.-1). Strains of Microcystis from the reservoir were tested for toxicity and contained high concentrations of microcystin indicating a highly serious health threat. Moreover, the same algal blooms may explain the occurrence of fish kills in the lake that was observed in 1996. A reduction of nutrient inputs in the reservoir is urgently required to prevent the occurrence of toxic algal blooms in the future. ····· 10361113014

Klimawandel und Umweltzerstörung sind die bestimmenden Schlagworte in den öffentlichen Debatten. Ein Paradebeispiel für den Raubbau an der Natur ist der Braunkohlenbergbau der DDR. Die Mangelwirtschaft der DDR verhinderte die gesetzlich vorgeschriebene Rekultivierung auf großer Fläche und förderte umweltschädliche Handlungsweisen der Betriebe. Die Sanierung der Braunkohlentagebaue ist daher eine der großen Gemeinschaftsaufgaben des Bundes und der betroffenen Länder in der Altlastensanierung. Doch bereits zu DDR-Zeiten gab es Wissenschaftler und engagierte private Naturfreunde, die erkannten, wie sich nach der Zerstörung neue Lebensräume entwickelten: Liegengelassene, nicht rekultivierte Flächen sind auch Räume spontaner Entwicklungen, Standorte mit extremen Boden-, Wasser,- und Mikroklimaeigenschaften. Sie bieten damit zahlreichen spezialisierten und gefährdeten Arten der Flora und Fauna Lebensräume. Einige wenige Kippenflächen und Halden wurden bereits damals unter Schutz gestellt. Heute sind 17 SPA-Gebiete, 28 FFH-Gebiete und 33 Naturschutzgebiete auf Flächen des Braunkohlenbergbaus in Ostdeutschland ausgewiesen. Durch die Sanierung der Braunkohlentagebaue wurden in dem vergangenen Vierteljahrhundert die meisten Umweltschäden erfolgreich und nachhaltig beseitigt. Flächen für Tourismus und wirtschaftliche Nachnutzung sind entstanden. Traktoren und Holzerntemaschinen sind in den Bergbaufolgelandschaften normale Anblicke. Doch wie steht es um die Naturschätze in den Bergbaufolgelandschaften Unter der Leitung von zwei wissenschaftlichen Institutionen und dem bundeseigenen Projektträger der Braunkohlensanierung haben insgesamt 6 Institutionen an diesem Werk mitgearbeitet. Über 100 Fachleute haben ihr Wissen, Daten und Bildmaterial zur Verfügung gestellt. Es ist ein einzigartiges Werk entstanden, das einen Einblick in die aktuelle Situation erlaubt. Für 29 Artengruppen mit vielen Hundert Arten werden die aktuelle Situation, erwartbare Trends sowie Möglichkeiten zur Stabilisierung und positiven Entwicklung detailliert beschrieben. Die Vergleiche zwischen dem Mitteldeutschen Revier, zwischen den Städten Leipzig, Halle, Gräfenhainichen und Altenburg, und dem Lausitzer Revier, um Cottbus südwärts bis in den Raum Weißwasser-Hoyerswerda-Görlitz, bringen spannende Erkenntnisse zur Verbreitung einzelner Arten und Gruppen. Die Ergebnisse zu Arten und deren Häufigkeiten sind weit über die Braunkohlefolgelandschaften von Bedeutung. Steckbriefe von 25 verschiedenen Biotop- und Vegetationstypen in den Bergbaufolgelandschaften beschreiben die Lebensräume und ihre Entwicklungstendenzen. Es werden zahlreiche Hinweise zum Schutz und der Pflege naturschutzrelevanter Biotoptypen gegeben. Dynamik und Vielfalt sind immer noch prägende Prozesse in den Bergbaufolgelandschaften. Das dem so ist, ist auch ein großer Verdienst privater und öffentlicher Naturschutzstiftungen. Deren aktive Mitarbeit an diesem Werk ermöglichte das dort vorhandene Wissen und die praktischen Erfolge in einer gemeinsamen Publikation darzustellen. Das Buch wendet sich damit an alle, die in der Rekultivierung von Bergbauflächen arbeiten, Wissenschaftler und Studierende aus den Bereichen der Biologie, Geoökologie und der Landschaftsgestaltung, an Spezialisten für die aufgeführten Artengruppen sowie an alle Naturbegeisterten. ····· 10361108235
für 48.80€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Ecological research on acidic lakes has historically focused on soft-waters, whereas biota in natural and man-made acidic hard-water lakes remains poorly studied. My thesis deals with the effects of multiple abiotic stressors on species and genetic biodiversity of littoral Cladocera in two types of acidic waters in Germany: hard-water mining and soft-water bog lakes. I found that these two types of acidic lakes supported highly distinct cladoceran communities, both with respect to their species diversity and composition, what led to the rejection of my null hypothesis that pH was the only abiotic factor, determining species diversity patterns. Further analyses revealed that, apart from pH, TDS-related parameters and trophy significantly affected species composition of littoral Cladocera in the studied lakes. Particularly the role of TDS and its constituents for colonization of acidic lakes was virtually neglected by previous studies, based on soft-water lakes` data sets. My study on the genetic diversity of a generalist cladoceran Chydorus sphaericus provided evidence for genetic erosion, i.e. negative effects of abiotic stress in the acidic hard-water mining lakes, but not in the acidic soft-water bog lakes. I conclude that the observed genetic erosion in acidic mining lakes may have negative long-term consequences for population persistence even in broadly tolerant species. In general, biodiversity at both species and genetic levels was much more impaired in the acidic hard-water mining lakes, compared to the naturally acidic soft-water bog lakes. This was possibly due to both ecological (higher abiotic stress) and evolutionary (insufficient time for long-term adaptations to evolve) mechanisms. My results suggest that colonization of acidic hard- and soft-water lakes in each case should require specific physiological adaptations at both species and population levels. The practical relevance of my studies is that they provide the scientific basis for monitoring of acidic hard-water mining lakes based on littoral Cladocera. Especially genetic diversity proved a valuable indicator of water quality in acidic mining lakes, as it provided unique information on population-level responses, being complementary to species diversity assessment. Overall, my results demonstrate that inclusion of acidic hard-water lakes into the research framework as well as comparisons among communities in chemically diverse acidic lakes can result in important new insights, concerning the community organization and adaptations in acidic environments. ····· 10361108046

These water quality parameters become more critical in intensive culture systems where fish is raised in artificial ponds with reduced self purification capabilities as compared natural systems. Ichthyology (from Greek: , ikhthus, `fish` and , logos, `study`) is the branch of zoology devoted to the study of fishes. This includes skeletal fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha).

Fish predation and food availability are driving forces in controlling food webs in freshwater ecosystems but the relative importance of one or the other factor is still a matter of discussion. Lake restoration usually seeks to reduce eutrophication either by direct suppression of zooplanktivorous fish or by addition of piscivorous fish. These methods reached only varied success. Successful ecosystem restoration needs a new theoretical approach that takes into account community structure and functional diversity. This book attempts to evaluate the relative roles of fish predation and food availability using controlled replicated in situ manipulation experiments. Since the founding supposition was that there would be shifts in the relative importance of top-down and bottom-up effects between seasons, experiments were performed in spring and winter. Moreover experiments were carried out in a shallow lake under Mediterranean climate as almost no data are available about top- down and bottom-up controls in warm countries.
