Seasonal Distribution Of Phytoplankton In Orduzu Dam Lake (Malatya, Turkey), Ahmet Kadri̇ Çeti̇n, Bülent Şen Jan 2004

Seasonal Distribution Of Phytoplankton In Orduzu Dam Lake (Malatya, Turkey), Ahmet Kadri̇ Çeti̇n, Bülent Şen

Turkish Journal of Botany

The species composition and seasonal distribution of phytoplankton in Orduzu Dam Lake was studied for a year. Diatoms (Bacillariophyta) were most diverse, followed by green algae (Chlorophyta), blue-green algae (Cyanophyta), euglenoids (Euglenophyta) and dinoflagellates (Dinophyta). A total of 117 taxa were recorded and the phytoplankton of the lake contained a large number of detached benthic algae. Phytoplankton assemblages were dominated by diatoms in all the periods investigated and centric diatoms were the most abundant. Overall phytoplankton density was high during the spring and summer months and the highest phytoplankton density was observed in August. The abundance of phytoplankton was positively …

A Study On Algae In Devegeçidi Dam Lake, Tülay Baykal, İlkay Açikgöz, Kazim Yildiz, Aysel Bekleyen

Turkish Journal of Botany

This research was carried out between 1995 and 1996 in Devegeçidi Dam Lake and a total of 112 taxa belonging to 5 divisions were identified, with 29 species belonging to Cyanophyta, 5 to Euglenophyta, 45 to Chlorophyta, 5 to Pyrrhophyta and 28 to Bacillariophyta. Microcystis aeruginosa Kütz. from the Cyanophyta was the most abundant and widespread species in phytoplankton. This was followed by Aphanizomenon floss - aquae (L.) Ralfs and Aulacoseira granulata (Ehr.) Simonsen as the second most abundant and widespread organisms. Pediastrum dublex Meyen, P. simplex var. duodenarium (Bailey) Rabenhorst and Ceratium hirundinella (O.F.Muell.) Duj. species were widely distributed …


A Taxonomic Study On The Phytoplankton Of Lake Uluabat (Bursa), Di̇dem Karacaoğlu, Şükran Dere, Nurhayat Dalkiran Jan 2004

A Taxonomic Study On The Phytoplankton Of Lake Uluabat (Bursa), Di̇dem Karacaoğlu, Şükran Dere, Nurhayat Dalkiran

Turkish Journal of Botany

The phytoplanktonic algal flora of Lake Uluabat was studied during July 1998- June 1999 by analysing samples taken each month from 5 sampling stations. Identified taxa (331) of the phytoplanktonic community are as follows: 152 Bacillariophyta, 89 Chlorophyta, 42 Cyanophyta, 31 Euglenophyta, 11 Dinophyta, 4 Cryptophyta and 2 Chrysophyta. Algal species which live in eutrophic water are dominant in the phytoplankton. Most of the species are characterised by their widespread presence, although it is also noted that some taxa are rarely found in Turkey.


New Record For A Dinoflagellate Species (Citharistes Regius Stein) In The Northern Levantine Basin (Eastern Mediterranean), Sevi̇m Polat Jan 2004

New Record For A Dinoflagellate Species (Citharistes Regius Stein) In The Northern Levantine Basin (Eastern Mediterranean), Sevi̇m Polat

Turkish Journal of Botany

The presence of a dinoflagellate species, Citharistes regius Stein belonging to genus Citharistes Stein, is reported for the first time from the eastern Mediterranean coast of Turkey. This species is also a first report for all Turkish seas and the Levantine Basin. Morphological characteristics of this species are described in detail and information about its ecological distribution is given.
