tailieunhanh - A new genus record for the freshwater algal flora of Turkey

The genus Hydrurus 1824 and a species belonging to this genus, Hydrurus foetidus (Villars) Trevisan 1848, are reported for the first time for Turkish inland waters. The morphological characteristics of this species are described and information about its ecological distribution is given. | Turk J Bot 31 (2007) 149-152 © TÜB‹TAK Research Note A New Genus Record for the Freshwater Algal Flora of Turkey Fatma ÇEV‹K1,*, Brian A.

Anahtar Sözcükler: Chrysophyceae, Hydrurus foetidus, fiiryan Nehri, Türkiye Introduction Chrysophyceae, or golden-brown algae, are widely distributed in inland waters. However, a few species are found in brackish or marine waters, and some of these apparently grow equally well in marine and inland waters (Van den Hook et al., 1997; Nicholls & Wujek, 2002). It was reported by Van den Hook et al. (1997) and Kristiansen (2002) that there are about 1000 species belonging to the chrysophytes and most are unicellular or colonial. A few have a simple multicellular organisation, such as simple filaments, with or without mucilage, or form a pseudoparenchymatous thallus. Hydrurus is a freshwater form, which has mostly been reported from streams and rivers in mountainous districts, especially during the colder months of the year (Lund & Lund, 1998). There is a single species, H. foetidus (Kristiansen, 2002). Perhaps because of .
