Investigating The Presence Of Cladocera Species Within The Wetlands Of Uae, Shamma Eisa Salem Shahdad Alneyadi

Theses

The wetlands ecosystems found in the Arabian Peninsula have been poorly investigated. Moreover, the available information about the presence of freshwater communities have been rarely documented. Although there are scattered records about the presence of freshwater Cladocera organisms within the Arabian Gulf countries; few of them have received proper taxonomic identification. Cladocera populations in freshwater bodies are always characterizing its water quality and other living invertebrates’ community. United Arab Emirates wetlands are among the ecosystems belonging to Ramsar convention for its conservation. The presence of both temporary and permanent freshwater area has been developed after the great interest to collect …

Variation In The Microbiota Associated With Daphnia Magna Across Genotypes, Populations, And Temperature, Jonas Frankel-Bricker, Michael J. Song, Maia J. Benner, Sarah Schaack

University Author Recognition Bibliography: 2020

Studies of how the microbiome varies among individuals, populations, and abiotic conditions are critical for understanding this key component of an organism’s biology and ecology. In the case of Daphnia, aquatic microcrustaceans widely used in population/community ecology and environmental science studies, understanding factors that influence microbiome shifts among individuals is useful for both basic and applied research contexts. In this study, we assess differences in the microbiome among genotypes of D. magna collected from three regions along a large latitudinal gradient (Finland, Germany, and Israel). After being reared in the lab for many years, we sought to characterize any …

Turkish Journal of Zoology

Troughs are one of the main components of villages in Turkey. They are constructed by converting springs or underground waters. Until now, there has been no extensive study investigating the composition and diversity of trough zooplankton species. In order to contribute knowledge on the zooplanktons in troughs, 142 troughs were randomly sampled from 17 districts in Ankara Province between 22 June and 3 July 2011. A total of 18 zooplanktons including 11 Copepoda and 7 Cladocera species were determined.

Turkish Journal of Zoology

The toxic effects of technical grade (95 %) malathion and commercial (25 %) malathion were investigated on young (£ 24 h old) Daphnia magna in static acute toxicity tests (24 and 48 h). The culture of D. magna and toxicity tests were performed at 24 ± 1 ºC with a photoperiod of 16 h light and 8 h dark. To obtain a healthy population, the fecundity of each female in their life cycle was also investigated. The immobilization of daphnids was considered for determination of the 24 h / 48 h effective concentration (50 %). The EC50 values were found …

The Cladocera Of Lake West Okoboji, Iowa - Revisited, Kenneth L. Lang

Journal of the Iowa Academy of Science: JIAS

Seven stations, established in 1968 to sample Cladocera, were sampled again, using the same methods, in 1988. Seven species, all of them in low abundance, are new records for Lake West Okoboji. In 1988, there was little difference 1) in the ranking of the stations relative to abundance of cladocerans, 2) the distribution and abundance of the species by habitat-type, 3) the seasonality of the predominant species in the specific habitats, 4) the temporal patterns of the number of species and total cladoceran abundance in the specific habitats, compared to 1968. On the average there were more species but lower …

Feeding Morphologies And Distribution Patterns Of Marine Cladocera In The Lower Chesapeake Bay, Sandra Layne Gilchrist

OES Theses and Dissertations

Temporal and spatial distributions of marine cladocera in the lower Chesapeake Bay estuary were observed over a year-long sampling period. The distributions of cladoceran species throughout the Bay were studied in relation to temperature and salinity. A survey of the species over the entire Bay is included to establish distribution patterns of the various species during a short time period.

Theoretical mathematical principles were used to predict feeding abilities of the Bay species. Mouthparts are described qualitatively and quantitatively to infer function. A mandibular index developed by Itoh (1970) was revised and employed in evaluating feeding methods interspecifically and interspecifically. …

Limnetic Zooplankton Dynamics In Beaver Reservoir Including An Inventory Of Copepod Species And An Evaluation Of Vertical Sampling Methods, Eugene H. Schmitz

Technical Reports

There can be little doubt that the development of primary food sources (i.e. plankton) is an important factor contributing to fish production. Applegate and Mullan (1968) report that an exceptional sport fish harvest is generally associated with the development of new reservoirs, although the precise reasons for such interrelations are not known. Kramer and Smith (1962) demonstrated the tendency of bass fingerlings to feed on Cladocera in proportion to the latter's abundance, and Hodson (1966) reported the same basic pattern for largemouth and spotted bass fingerlings in Beaver Reservoir. Applegate and Mullan (1969) analyzed the digestive tract contents of larval …
