The zooplankton of some mountain lakes in the Taurus Range (Turkey)

Abstract The zooplankton of 16 mountain lakes in the Taurus Range was studied during 1996 and 1997, and a total of 116 zooplankton taxa, comprising 69 rotifers, 33 cladocerans, 12 copepods, one anostracan, and one chonchostracan was identified. Four rotifers (Brachionus polyacanthus, Asplanchnopus hyalinus, Lecane haliclysta, Dissotrocha aculeata medio-aculeata) and one copepod (Arctodiaptomus (Rh.) alpinus) are new for Turkish inland waters, and they are illustrated.

A new locality for the freshwater jellyfish Craspedacusta sowerbyi Lankester, 1880 in Turkey

Abstract The freshwater jellyfish Craspedacusta sowerbyi was found regularly at Topçam Reservoir, Aydın province, Turkey, between June 1999 and June 2000. It is thought that the species has been unintentionally introduced into the reservoir together with fishes. This is one of the first records for Turkey.

The freshwater leeches (Annelida: Hirudinea) of the Gediz catchment area (Izmir region)

Very little literature is available on the freshwater leeches of the Aegean region of Turkey. GELDIAY & TAREEN (1972) studied the benthic fauna of Gölcük Lake (Bozda ) and found five leech species (Helobdella stagnalis, Piscicola geometrica, Hirudo medicinalis, Erpobdella octoculata and Erpobdella testacea). KAZANCI et al. (1992) mentioned the presence of Haementaria costata and Dina lineata in the Köyce iz-Dalyan area. USTAO LU et al. (1998) reported six leech species (Haementaria costata, Hemiclepsis marginata, H. stagnalis, Glossiphonia complanata, Haemopis sanguisuga and E. octoculata) from Tahtal Dam Lake, and BALIK et al. (1999) studied rivers of the Northern Aegean region and reported two leech species (H. stagnalis and E. octaculata). KASPAREK et al. (2000) studied the distribution

Littoral Oligochaeta (Lumbriculidae and Enchytraeidae) communities of some mountain lakes in the Eastern Black Sea Range (Turkey)

Abstract Six surveys were carried out during July and August 2005–2007 in order to determine the Oligochaeta fauna of high-altitude lakes located in the Eastern Black Sea Range. With the highest peak, Kaçkar Dagi (elevation 3937 metres), and mountain plateaus at about 3000 metres in elevation, are the highest part of the Eastern Black Sea Range. This range is one of the most important glacial region in Turkey. Some physico-chemical features and Oligochaeta fauna of 39 lakes were determined for the first time, where no previous faunistic studies took place. As a result of the study, a total of 10 taxa was identified, comprising 3 species from Lumbriculidae [(Stylodrilus parvus (Hrabë & Černosvitov, 1927), Stylodrilus heringianus Claparede, 1862, and Lumbriculus variegatus (Müller, 1774)], 7 taxa from Enchytraeidae [(Cognettia sphagnetorum (Vejdovsky, 1878), Cognettia glandulosa (Michaelsen, 1889), Mesenchytraeus armatus (Levinsen, 1884), Mesenchytraeus sp., Henlea ventriculosa (d’Udekem, 1854), Henlea perpusilla Friend, 1911, and Henlea sp.)]. All the taxa represent new records for the region. Stylodrilus heringianus is recorded for the first time in Turkey.

An amphipod species new for the Turkish fauna: Pontogammarus aestuarius (Derzhavin, 1924)

Abstract Pontogammarus aestuarius (Derzhavin, 1924), a Ponto-Caspian amphipod species, was found in 2002 in Taşkısığı Lake, situated on the NW coast of Anatolia. Its morphological characteristics are described and the extremities of the male illustrated. Ecological notes on the habitat of the species are given.

A preliminary study on the zooplankton composition of some lakes in the Western Black Sea Region (Turkey)

Bati Karadeniz Bolgesi’nde bulunan on uc golun (Poyrazlar Golu, Kucuk Akgol, Taskisigi Golu, Buyuk Akgol, Acarlar Golu, Melen Golu, Yenicaga Golu, Abant Golu, Golcuk Golu, Karamurat Golu, Suluklu Gol, Cubuk Golu, Sunnet Golu) zooplankton faunasi incelenmistir. Her golde 2002 ve 2003 yazinda iki plankton orneklemesi yapilmistir. Calisma sonucunda rotiferlerden 69, kladoserlerden 25 ve kopepodlardan 13 olmak uzere toplam 107 takson saptanmistir.

Rotifer fauna of Lake Yayla (Denizli-Turkey)

The rotifer fauna of Lake Yayla was studied seasonally between 2000- 2002. The rotifer samples were collected by using plankton net with the mesh size of 55 µm horizontally and preserved in 4 % formaldehyde. As a result, 64 taxa in 17 families were identified and reported firstly from Lake Yayla. Besides, Colurella uncinata deflexa , Lepadella (H.) heterostyla and Lepadella (L.) patella oblonga are new species for the Turkish inland waters fauna.

Denizli’deki dağ göllerinin Oligochaeta (Annelida) faunası üzerine gözlemler

Oz: Sandiras ve Cicekbaba Daglari zirvelerinde yer alan Kartal Golu ve zirveye yakin Gokceova Goleti, Honaz ilcesi yakinlarindaki Sakligol ve Bozkurt ilcesi yakinlarindaki Karagol’un Oligochaeta (Annelida) faunasini belirlemek uzere 2009, 2010 ve 2011 yillari Haziran, Temmuz ve Agustos aylarinda 4 ornekleme calismasi yapilmistir. Kalitatif degerlendirmeler sonucunda, ornekleme yapilan gollerin tumunden degisen sayilarda oligoket turleri tespit edilmis, 3 ordo iceriginde 3 familyaya ait bireyler tanimlanmistir. 17’si Naididae (14’u Tubificinae altfamilyasi, 3’u Naidinae altfamilyasi), 1’i Lumbriculidae ve 3’u Enchytraeidae olmak uzere toplam 21 Oligochaeta taksonu saptanmistir.

Turlerin istasyonlara ve ornekleme tarihlerine gore dagilimlari verilmistir. Mevcut calisma ile Turkiye’nin en onemli ve verimli laguner alanlarindan biri olan Karina Lagunu’nde dagilim gosteren Malacostraca turleri tespit edilerek Turkiye biyo-cesitliligi hakkindaki bilgilere katki yapilmasi amaclanmistir

Yaz aylarında Batı Anadolu’nun bazı dağ göllerinin (Denizli-Muğla) fitoplankton kompozisyonu ve trofik durum indeksi değerleri

Bati Anadolu’nun daglik alanlarinda yer alan Sakligol, Karagol, Gokceova Goleti, Kartal Golu olmak uzere 4 golden fitoplankton ve yuzey suyu orneklemeleri yapilmistir. Bu gollere kis ulasiminin zor olmasindan dolayi, 2009, 2010, 2011 yillarinin yaz aylari ornekleme zamani olarak tercih edilmistir. Yapilan incelemeler sonucunda, Cyanobacteria (5), Bacillariophyta (22), Ochrophyta (3), Chlorophyta (16), Charophyta (6), Miozoa (3) ve Euglenophyta (4) divizyolarina dahil 59 takson teshis edilmistir. Sakligol’den 23, Gokceova Goleti’nden 26, Kartal Gol’unden 21 ve Karagol’den 24 fitoplankton taksonu saptanmistir. Sonuc olarak, gollerin fitoplankton kompozisyonu ve diger bazi ekolojik degerleri, inceleme yapilan gollerin verimlilik durumunun oligotrofik oldugunu gostermektedir. Bu calismada, Turkiye’nin dag gollerinin fitoplankton kompozisyonu ve limnolojisi hakkindaki bilgilere katkilar saglanmasi amaclamistir
