Available in PDF, EPUB and Kindle. Book excerpt: Ecosystems change on a multitude of spatial and temporal scales. While analyses of ecosystem dynamics in short timespans have received much attention, the impacts of changes in the long term have, to a great extent, been neglected, provoking a lack of information and methodological know-how in this area. This book fills this gap by focusing on studies dealing with the investigation of complex, long-term ecological processes with regard to global change, the development of early warning systems, and the acquisition of a scientific basis for strategic conservation management and the sustainable use of ecosystems. Within this book, theoretical ecological questions of long-term processes, as well as an international dimension of long-term monitoring, observations and research are brought together. The outcome is an overview on different aspects of long-term ecological research. Aquatic, as well as terrestrial ecosystems are represented.
Download or read book Dhaka Megacity written by Ashraf Dewan and published by Springer Science & Business Media. This book was released on 2013-09-09 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book Dhaka Megacity: Geospatial Perspectives on Urbanisation, Environment and Health presents the use of geospatial techniques to address a number of environmental issues, including land use change, climatic variability, urban sprawl, population density modelling, flooding, environmental health, water quality, energy resources, urban growth modelling, infectious diseases and the quality of life. Although the work is focused on the Megacity of Dhaka in Bangladesh, the techniques and methods that are used to research these issues can be utilized in any other areas where rapid population growth coupled with unplanned urbanization is leading to environmental degradation. The book is useful for people working in the area of Geospatial Science, Urban Geography, Environmental Management and International Development. Since the chapters in the book cover a range of environmental issues, this book describes useful tools for assisting informed decision making, particularly in developing countries.

Download or read book Shallow Lakes 95 written by Lech Kufel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shallow lakes differ from deep ones in many aspects of nutrient dynamics, biotic structure and interactions of various trophic levels. Though very common in European lowlands, shallow lakes attract inadequate attention from research teams. This book aims at filling gaps in our knowledge of the processes which take place in non-stratified lakes. It contains proceedings from the international conference `Shallow Lakes *95' held in Mikolajki, Poland, on 20-26 August 1995. In more than 50 original papers up-to-date views on eutrophication, degradation and recovery of shallow lakes are presented. The first four sections of the book (Nutrient fluxes, Biotic structure, Trophic interactions and Whole lake studies) deal with theoretical aspects of lake functioning while the fifth (Biomanipulation, restoration and management) is devoted to practical measures undertaken to improve water quality in shallow lakes. The book is therefore addressed to university biologists and ecologists and PhD students, as well as to managers involved in restoration of shallow lakes.
Download or read book Spatiotemporal Analysis of Lake Water Quality Indicators on Small Lakes Lake Bloomington and Evergreen Lake in Central Illinois Using Satellite Remote Sensing written by Gare Ambrose-Igho and published by . This book was released on 2020 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research explores the use of Sentinel-2 satellite to determine the spatiotemporal patterns of lake water quality indicators (e.g. chlorophyll a) in Lake Bloomington and Evergreen Lake. Lake water quality issues related to algal blooms is a serious problem in basins with abundant agricultural lands causing harmful effects to freshwater ecosystems such as pollution of beaches, taste and odor problems in drinking water, depletion of oxygen levels causing fish kills and the issue of water exceeding safe drinking water standards. Developing monitoring techniques using various water quality indicators of algal blooms is crucial. In this project, remote sensing and field sampling methods were employed to assess the state of water quality of two small lakes, Lake Bloomington and Evergreen Lake, in Central Illinois. Water samples were collected from selected locations from the lakes to test for various water quality variables including nitrate, phosphorus and chlorophyll a. An exo sonde instrument and secchi disk was used to measure additional water quality parameters such as turbidity, secchi depth, and temperature. Concurrent satellite images obtained from Sentinel-2 with flyover with ℗ł5 days were processed and analyzed, and the results were compared with field sampling data. Single and multiple pixel analyses were conducted on various algorithms such as Bottom-of-Atmosphere (BOA), Maximum Chlorophyll Index (MCI), and band ratios. These algorithms were tested to identify the best algorithm for estimating water quality parameters using satellite data for the two lakes. A regression analysis was conducted to derive a linear model which was used to create water quality indicator maps that showed the spatial pattern of algae in the lakes. From the results of the research, Lake Bloomington was more turbid and had higher concentrations of chlorophyll a than Evergreen Lake. Except for band ratio of B1/B2 of Sentinel-2 data, a poor regression relationship between satellite and field water quality values was observed for Lake Bloomington. This poor relationship could be due to the high turbidity of the lake. Evergreen Lake, on the other hand, showed a stronger relationship between satellite values and chlorophyll a. Generally, spatial analysis reveals that chlorophyll a distribution was heterogeneous, and it increased from downstream areas to upstream areas.
