Book excerpt: Master's Thesis from the year 2005 in the subject Biology - Zoology, grade: Degree Awarded, University College Cork, language: English, abstract: Ballincollig reservoir is a small eutrophic lake located west of Cork city and south of Ballincollig town in county Cork, Ireland. The reservoir was studied for six months, from 7th February through 27th July, for the factors that may influence or regulate population dynamics (i.e. abundance and size structure) of the crustacean zooplankton. Various physico-chemical and biological parameters were measured and related to abundance and size structure of the crustacean zooplankton species/groups using the non-parametric Spearman's correlation test. Friedman's test was employed for the purpose of data analysis. Three cladoceran species: B. coregoni Baird, B. longirostris O.F.Muller, D. hyalina Leydig, and a genus Ceriodaphnia Dana as well as cyclopoid copepods were investigated during the study period. Water variables such as subsurface water temperature, dissolved oxygen, conductivity, and pH as well as secchi depth and chlorophyll a concentration did not show statistically significant spatial variation within the reservoir where as they varied significantly over time. Factors such as fish predation (top-down control), type and availability of phytoplankton (bottom-up control), water temperature and competition for resources among the crustacean zooplankton were found to regulate or influence abundance and size structure of the crustacean zooplankton. Top-down control by fish was important particularly in structuring the spatial dynamics of the crustacean zooplankton population within the reservoir whereas bottom-up control, water temperature and competition regulated mainly the temporal trend of the population dynamics. The cyprinid fish fauna appeared to influence the temporal dynamics of the crustacean zooplankton rather indirectly through enhancement of phytoplankton availability by stirring up the nutrients from the s

Available in PDF, EPUB and Kindle. Book excerpt: All relevant ecological aspects of plankton, especially seasonal changes in the species composition, the role of competition for limiting resources in species replacements, the role of parasitism, predation and competition in seasonal succession are treated in detail considering phytoplankton, zooplankton and bacteroplankton. In addition to its use as a valid reference book for plankton ecology, this monograph may well be used as a model for other kinds of ecological communities.

Available in PDF, EPUB and Kindle. Book excerpt: Sun, wind and water draining from the land interact with the morphological features of a water body to create the environment experienced by freshwater plants and animals. The result of this interaction can be considered as the freshwater hydro climate and this plays the same role as that of conventional climate in terrestrial ecology. Agriculture, for example, has long been supported by specialist meteorological services which not only provide farmers with a sound interpretation of weather and climate without excessive technicality but which also consider relations between climate and the growth of crops and stock. There is a need for a similar service in freshwater ecology and applied biology. This book is the result of a number of years devoted to developing part of that service. It concentrates on the influence of all forms of water movement on the ecology of fresh waters. Water movement implies interest in both the quantity of water moving through river basins which reflects the climate of the catch ment as well as the nature of the fluid motion within the rivers and lakes of the basin. The book is not so much a review of recent research as an attempt to establish a logic-how knowledge of water movement can contribute to understanding the ecology of fresh waters. Two points follow directly.
Download or read book Freshwater Crustacean Zooplankton of Europe written by Leszek A. Bledzki and published by Springer. This book was released on 2016-07-20 with total page 923 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work provides a user-friendly, species level taxonomic key based on morphology, current nomenclature, and modern taxonomy using molecular tools which fulfill the most pressing needs of both researchers and environmental managers. This key arms the reader with the tools necessary to improve their species identification abilities. This book resolves another issue as well: the mix of female and male characters used in keys to the calanoid copepods. Often, during the identification process, both calanoid copepod sexes are not available, and the user of such a key is stuck with an uncertain identification. Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.

Download or read book Adaptive Catchment Management and Reservoir Operation written by Guangtao Fu and published by MDPI. This book was released on 2019-04-09 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: River catchments and reservoirs play a central role in water security, food supply, flood risk management, hydropower generation, and ecosystem services; however, they are now under increasing pressure from population growth, economic activities, and changing climate means and extremes in many parts of the world. Adaptive management of river catchments and reservoirs requires an in-depth understanding of the impacts of future uncertainties and thus the development of robust, sustainable solutions to meet the needs of various stakeholders and the environment. To tackle the huge challenges in moving towards adaptive catchment management, this book presents the latest developments in cutting-edge knowledge, novel methodologies, innovative management strategies, and case studies, focusing on the following themes: reservoir dynamics and impact analysis of dam construction, optimal reservoir operation, climate change impacts on hydrological processes and water management, and integrated catchment management.

This book was released on 2012-12-06 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the Proceedings of the Symposium on Perspectives in Southern Hemisphere Limnology which was held from 3-13 July 1984 in Wilderness, South Africa. It can be asked why this Symposium was necessary at a time when conferences, symposia and other gatherings of learned people abound. Limnologists in the Southern Hemisphere have for some time been pointing out that limnological theory and inland water management practices have been developed almost exclusively in Northern Hemisphere temperate latitudes. Most of the land masses of the Southern Hemisphere fall within lower latitudes, 0 from 20-40 S, where the climate tends to be dry, with low cloud cover and with high levels of incident radiation and high water temperatures. Wide extremes are experienced in both rainfall and runoff, which occur mainly in summer. Sedimentary geological structures give rise to dispersive soils and highly turbid waters. Physiological, behavioural or developmental adaptations in the floral and faunal components are necessary to cope with desiccation and low visibility.
