Book Limnetic Crustacean Zooplankton of Lake Oahe May October 1969

Download or read book Limnetic Crustacean Zooplankton of Lake Oahe May October 1969 written by James H. Selgeby and published by . This book was released on 1974 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The limnetic crustacean zooplankton of Lake Oahe was dominated by copepods. Cyclops biscupidatus thomasi was the dominant crustacean throughout the lake. Mesocyclops edax, Diaptomus ashlandi, and Daphnia pulex were major components of the zooplankton in the deep, downstream portion of the lake while Bosmina longirostris and Daphnia retrocurva were important constituents in the river-like, upstream section of the lake.

Book Zooplankton of the Great Lakes

Download or read book Zooplankton of the Great Lakes written by Mary D. Balcer and published by Univ of Wisconsin Press. This book was released on 1984 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers, instructors, and students will appreciate this compilation of detailed information on the crustacean zooplankton of the Great Lakes. The authors have gathered data from more than three hundred sources and organized into a useful laboratory manual. The taxonomic keys are easy to use, suitable for both classroom and laboratory identifications. Detailed line drawings are provided to help confirm the identification of the major species. Zoologists, limnologists, hydrobiologists, fish ecologists, and those who study or monitor water quality will welcome this dependable new identification tool. A concise summary of pertinent information on the ecology of these zooplankton is provided in the main body of the text. A check-list of all species reported from each of the Great Lakes and notes on the distribution and abundance of more than a hundred species were compiled from an extensive search of existing literature. In addition, the authors collected samples from several locations on Lake Superior, in order to provide information on the abundance and life histories of the major crustacean species.

Book Diel Vertical Migration of Zooplankton in Lakes and Oceans

Download or read book Diel Vertical Migration of Zooplankton in Lakes and Oceans written by Joop Ringelberg and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover distances of 10–40 m in lakes or even a few hundred metres in the open oceans. Although not as spectacular as migrations of birds or the massive movements of large mammals over the African savannas, the numbers involved are very large and the biomass exceed the bulk of the African herds. For example, in the Antarctic oceans swarms of “Krill” may cover kilometres across, with thousands of individuals per cubic metre. These Euphausiids are food for whales, the most bulky animals on earth. Zooplankton are key species in the pelagic food web, intermediary between algae and ?sh, and thus essential for the functioning of the pelagic community. Prey for many, they have evolved diverse strategies of survival and DVM is the most imp- tant one. Most ?sh are visually hunting predators and need a high light intensity to detect the often transparent animals. By moving down, the well-lit surface layers are avoided but they have to come up again at night to feed on algae.

Book Factors Influencing the Dynamics of Crustacean Zooplankton in a Small Eutrophic Reservoir

Download or read book Factors Influencing the Dynamics of Crustacean Zooplankton in a Small Eutrophic Reservoir written by Mulugeta Wakjira and published by . This book was released on 2017-06-08 with total page 128 pages. Available in PDF, EPUB and Kindle. 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

Book Zooplankton Diversity and Pelagic Food Webs

Download or read book Zooplankton Diversity and Pelagic Food Webs written by Marina Manca and published by MDPI. This book was released on 2021-05-04 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zooplankton are of key importance in the structure and functioning of aquatic food webs. They contribute to a large part of the functional and structural biodiversity of predator and prey plankton communities. Promptly responding to long-term and seasonal changes in the physical and chemical environment, they are sensitive indicators of patterns and mechanisms of impact drivers, both natural and human induced. In this volume, we aim to present evidence for both long-term and seasonal changes in zooplankton community structure and dynamics, investigating different approaches from population dynamics to advanced molecular techniques and reconstructing past communities from subfossil remains in lake sediments.
