This book was released on 1995 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of an experiment conducted in artificial streams in which the growth of benthic algae was studied in relation to the phosphorus and nitrogen concentrations in the water. The goal of the study was to determine whether benthic algal biomass in the upper Athabasca River is limited by the availability of phosphorus or nitrogen. The results include the taxonomic, growth, and biomass responses by periphytic algae to phosphate additions of up to 50 micrograms per liter. The report also develops a model describing change in relative peak biomass with phosphorus addition, using data from the Athabasca experiments. Comparisons are made with a similarly derived model using results from experiments on the South Thompson River.

Book excerpt: Presents results of an experiment conducted in artificial streams (flumes) in which the growth of periphyton (algae) was studied in relation to phosphorus concentrations in the water. The goal of the study was to determine whether periphyton growth in the Athabasca River was phosphorus limited and whether the degree of phosphorus limitation varied seasonally. The experimental flumes were located on site, adjacent to the Athabasca River at Hinton. The experiment was designed to test periphyton growth and biomass response to a gradient of phosphorus additions during fall and early spring. Periphyton response was compared for phosphorus additions of zero (control), 1, 10, and 25 micrograms per litre of phosphorus (spring and fall 1994) or zero, 0.1, 0.2, 1, 5, 10, 25, and 50 micrograms per litre of phosphorus (fall 1993). Results include relative specific growth rates as indicated by measuring the build-up of chlorophyll a, the level at which growth rate saturation occurred, and phosphorus concentrations required to reach maximum biomass levels.

Available in PDF, EPUB and Kindle. Book excerpt: This book critically discusses different aspects of algal production systems and several of the drawbacks related to microalgal biomass production, namely, low biomass yield, and energy-consuming harvesting, dewatering, drying and extraction processes. These provide a background to the state-of-the-art technologies for algal cultivation, CO2 sequestration, and large-scale application of these systems. In order to tap the commercial potential of algae, a biorefinery concept has been proposed that could help to extract maximum benefits from algal biomass. This refinery concept promotes the harvesting of multiple products from the feedstock so as to make the process economically attractive. For the last few decades, algal biomass has been explored for use in various products such as fuel, agricultural crops, pigments and pharmaceuticals, as well as in bioremediation. To meet the huge demand, there has been a focus on large-scale production of algal biomass in closed or open photobioreactors. Different nutritional conditions for algal growth have been explored, such as photoautotrophic, heterotrophic, mixotrophic and oleaginous. This book is aimed at a wide audience, including undergraduates, postgraduates, academics, energy researchers, scientists in industry, energy specialists, policy makers and others who wish to understand algal biorefineries and also keep abreast of the latest developments.

Book excerpt: Ponds and small lakes support an extremely rich biodiversity of fascinating organisms. Many people have tried pond-dipping and encountered a few unfamiliar creatures, such as dragonfly nymphs and caddisfly larvae. However, there is a far richer world of microscopic organisms, such as diatoms, desmids and rotifers, which is revealed in this book. Anyone with access to a microscope can open up this hidden dimension. Identification keys are provided so that readers can identify, explore and study this microscopic world. There are also many suggestions of ways in which readers can then make original contributions to our knowledge and understanding of pond ecology. The book not only explores the fascinating world of the creatures within ponds and their interactions, but also explains the many ways in which ponds are important in human affairs. Ponds are being lost around the world, but they are a key part of a system that maintains our climate. In the face of climate change, it has never been more important to understand the ecology of ponds. Includes keys to: A - Traditional key to kingdoms of organisms; B - Contemporary key to kingdoms of organisms; C - Pragmatic key to groups of microorganisms; D - Algae visible, at least en masse, to the naked eye; E - Periphyton, both attached to surfaces and free living; F - Protozoa; G- Freshwater invertebrates and; H - Common phytoplankton genera in ponds.
