Resting spores of the freshwater diatoms Acanthoceras and Urosolenia
نویسندگان
چکیده
Diatom resting spores are a widespread, but sometimes misconstrued component of siliceous micro fossil assemblages. We illustrate and discuss resting spore morphology found in populations of Acanthoceras and Urosolenia, two widely distributed freshwater genera. Taxonomic status of these genera and the potential paleolimnologic interpretation of resting spores are discussed.

Three extant genera of freshwater thalassiosiroid diatoms from Middle Eocene sediments in northern Canada.
The evolutionary history of diatoms is only constrained partially by the fossil record. The timing of several key events, such as initial colonization of freshwater habitats by marine taxa, remains poorly resolved. Numerous specimens of the genera Cyclotella, Discostella, and Puncticulata (Ochrophyta: Thalassiosirales) have been recovered in Middle Eocene lacustrine sediments from the Giraffe P...
متن کاملDiatom assemblages and Holocene sea level changes at the Tamatsu site in Kobe, western Japan1)
Diatom assemblages were analysed to clarify the changes in sedimentary environments caused by the Holocene sea level changes, and the results were cross-checked with information from the field observations of sedimentary facies. Diatoms were grouped into three ecological categories; marine, brackish and freshwater. Based on the ecological spectrum of the diatoms, the sediments were divided into...

Phytoplankton are the base of production in aquatic ecosystems and have a major importance in the freshwater environment both in terms of fundamental ecology and in relation to human use of natural resources. The purpose of this research was to determine distribution, abundance and biodiversity of phytoplankton community in Hanna Dam Lake, located in Isfahan province. The sampling was carried o...
متن کاملSeasonal variations in the epilithic diatoms of Koçan Falls (Erzincan, Turkey)
The present study explores some physical and chemical parameters in the epilithic diatoms in the water samples obtained from two stations in Koçan Falls, Erzincan from March to November 2014. Over the course of the study, 19 taxa of epilithic diatoms were recorded. Diatom genera which had the highest number of species in the study period were Cymbella (4 species), Navicula (4 species), and Cycl...
متن کاملDiatom flux reflects water-mass conditions on the southern Northwind Abyssal Plain, Arctic Ocean
We studied time-series fluxes of diatom particles from 4 October 2010 to 18 September 2012 using bottomtethered moorings with two sediment traps deployed at 180 and 1300 m depths at Station NAP (75 N, 162W; 1975 m water depth) in the western Arctic Ocean. This paper discusses on the relationship of time-series diatom fluxes to satellite-based sea-ice motion and simulated hydrographic variations...
