This book was released on 2013-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compilation provides systematic and detailed insight into the functioning of the pelagic communities of the Great Lakes. It is not simply about carbons or phosphorus interacting with packets of chlorophyll but rather about the complex processes and dynamic consequences of these unique inland lakes. Volume 1 focuses on the Lower Great Lakes, Lakes Ontario and Erie, while volume 2 highlights Lakes Michigan, Huron, and Superior, including a synthesis chapter for both the volumes.

This book was released on 2008 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: My doctoral thesis challenges the traditional paradigm of phosphorus (P) limitation of phytoplankton communities in freshwaters by suggesting colimitation of P, nitrogen (N), and iron (Fe) in Great Lakes. Oceanographers have recognized Fe, N and P colimitation, and biomass response to Fe is documented in freshwater lakes. I studied African and North American Great Lakes that are similar to large inland oceans. I discovered that Fe is a key nutrient that is often limiting in the offshore, and may explain the dominance of cyanobacteria in nutrient enriched lakes. I also discovered that the nearshore and offshore areas of these large lakes are very different, particularly when invasive dreissenid mussels are impacting the nearshore, as seen in the eastern basin of Lake Erie. As a result of the dreissenids, chlorophyll a (chla) concentrations are significantly lower in the nearshore of Lake Erie, but higher in the nearshore in the three African Great Lakes, as well as pre-dreissenid Lake Erie. The objective of my thesis was to determine the limiting nutrient(s) to the phytoplankton of the Great Lakes Erie, Malawi, Tanganyika, and Victoria in both the nearshore and offshore by measuring the physiological status of the phytoplankton. I also examined how dreissenids affect the distribution of seston and nutrient concentrations between the nearshore and offshore of the eastern basin of Lake Erie. My study design included temporal and spatial surveys in the nearshore and offshore of the four lakes, in which I used a variety of nutrient limitation indicators for P (C:P, N:P, P debt, APA, Fv/Fm), N (C:N, NH4 debt, NO3 debt, Fv/Fm), and Fe (Fv/Fm), as well as photosynthetic efficiency (Fv/Fm) experiments. Nutrient enrichment experiments were also conducted in the nearshore and offshore of the eastern basin of Lake Erie which involved the addition and removal of Fe alone, as well as in combination with P and/or N. Lake Erie nutrient enrichment experiments provided evidence for P, N and Fe colimitation where the addition of Fe with P relieved Fe and P limitation and allowed nitrate (NO3- ) assimilation, alleviating N limitation. However, the offshore experiments indicated stronger Fe limitation than the nearshore experiment. Lower chla concentrations in the post-dreissenid nearshore of the eastern basin of Lake Erie may not be due entirely to lower phytoplankton biomass, as photoacclimation of the phytoplankton may also be occurring. Dreissenid grazing effects can be seen in the distribution of dissolved nutrient concentrations between the nearshore and offshore of post-dreissenid Erie. The African Great Lakes are threatened by expanding human populations, resulting in increased nutrient runoff; the consequences of which will depend on the limiting nutrient(s). I found that the nearshore regions of Lakes Malawi and Tanganyika were colimited by N and P, while the offshore regions were colimited by N, P and Fe. The nearshore of Lake Victoria was colimited by light and N, while the offshore was colimited by N, P and Fe. Fe limitation only occurs in the offshore, and positive, significant relationships were found between total dissolved Fe concentrations and cyanobacteria. Continued P and Fe loading to the lakes will create a higher N demand that will result in a shift to N2-fixing cyanobacteria, which has serious consequences to human and ecosystem health as they are a poor nutritive food source and some are potentially toxigenic. The majority of studies conducted on Great Lakes involve offshore sampling, however, the less understood nearshore is where human impacts and activities are concentrated. I discovered there are significant differences between the nearshore and offshore, which has implications for water quality monitoring.

Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Algae of North America: Ecology and Classification, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth. This single volume brings together experts on all the groups of algae that occur in fresh waters (also soils, snow, and extreme inland environments). In the decade since the first edition, there has been an explosion of new information on the classification, ecology, and biogeography of many groups of algae, with the use of molecular techniques and renewed interest in biological diversity. Accordingly, this new edition covers updated classification information of most algal groups and the reassignment of many genera and species, as well as new research on harmful algal blooms. - Extensive and complete - Describes every genus of freshwater algae known from North America, with an analytical dichotomous key, descriptions of diagnostic features, and at least one image of every genus. - Full-color images throughout provide superb visual examples of freshwater algae - Updated Environmental Issues and Classifications, including new information on harmful algal blooms (HAB) - Fully revised introductory chapters, including new topics on biodiversity, and taste and odor problems - Updated to reflect the rapid advances in algal classification and taxonomy due to the widespread use of DNA technologies
