For thousands of years, Turkey has served as the cultural “bridge” and melting pot of the European, Asian, and African continents. It has been subject to human migration and settlement throughout its long history. Turkey (26–45°E, 36–42°N) is a transcontinental country encompassing an area of 784,000 km². About 97% of the country is in Asia Minor (...

Rivers of Europe, Second Edition, presents the latest update on the only primary source of complete and comparative baseline data on the biological and hydrological characteristics of more than 180 of the highest profile rivers in Europe. With even more full-color photographs and maps, the book includes conservation information on current patterns...

Cornigerius species are endemic to the Ponto-Caspian, with the exception of Cornigerius lacustris, which is endemic to freshwater Lake Hazar in the Euphrates basin. However, the barcoding fragment of the cytochrome c subunit I (COI) of animals from the type locality shows less than 1 % divergence with Black Sea and less than 2% with Caspian Lake C....

In this study Cyanobacteria species of Mogan Lake, Beytepe Pond and Delice River were taxonomically investigated. The cyanobacteria specimens have been collected by monthly intervals from Mogan Lake and Beytepe Pond between October 2010 and September 2011. For the Delice River the laboratory samples which were collected by montly intervals between...

Lagoons are valuable ecosystems providing various services, such as fishing, recreational activities, and land reclamation, as well as hosting high biodiversity. Although lagoons in Turkey cover a coastal area of more than 36,000 ha, few studies of them have been conducted. Therefore, two lagoons (Dalyan and Arapçiftliği) located on the coast of th...

Zooplankton plays a key role in aquatic environments maintaining clear water conditions at low predation pressure via grazing on phytoplankton; thus, they can be sensitive indicators of environmental disturbances. According to climate predictions, arid and semi-arid regions will become warmer, and a critical consequence for lake ecosystems is salin...

In a book chapter containing the first checklist and distribution of Turkish rotifers, published in 1999, were listed 167 taxa. Th e second checklist, published in 2004, reported 229 rotifer taxa in Turkey. During the 7 years since this checklist process, many studies have been carried out and we have prepared a new checklist of Turkish rotifers in...

Lake Uluabat, Bursa, Turkey, was sampled monthly between December 2001 and November 2002 at four stations for the purpose of evaluating the spatial and seasonal variations in the diversity and abundance of benthic macroinvertebrates in relation to the dynamics of water temperature, conductivity, water transparency, pH, dissolved oxygen, phosphate,...

Publisher Summary Geologically, Turkey is a part of the Alpine belt that extends from the Atlantic Ocean to the Himalayan Mountains. This belt started to form in the early Tertiary when the Arabian, African, and Indian plates collided with the Eurasian plate. Since the late Tertiary, Turkey has been moving toward the Eurasian plate whose resistance...

The accumulation of heavy metals such as Pb, Hg, Co, Cr, Cu, Zn, and Br were determined in water, sediment, muscle, and gill of three fish species (Leuciscus cephalus, Capoeta tinca, Capoeta capoeta) which were collected in Kızılırmak River Basin (Delice River). The metal concentration showed a general trend of Br>Zn> Pb>Cr>Cu>Hg>Co in water and Cr...

Uluabat Lake is one of the RAMSAR wetlands and it is under the threat of human activities such as drainage of irrigable lands and industrial, domestic and agricultural pollution. The objective of the current study was to investigate the distribution patterns and composition of the zooplankton (especially rotifers) regarding the physical and chemica...

Lake Uluabat is one of the RAMSAR site wetland which is under the threat of human activities such as drainage of irrigable lands and pollution from industrial, domestic and agricultural sources. The objective of this study was to investigate the distribution patterns and composition of zooplankton, phytoplankton, benthic macroinvertebrates consider...

The Uluabat Lake is a reservoir of 125 km2 surface area, in the boundaries of Bursa province, Turkey. The results showed that Uluabat Lake was still contaminated by organochlorine pesticides and their residues despite the existence of bans over a long time. Considerable amounts of organochlorine pesticides (HCB, p.p'-DDT, p.p'-DDE, alpha-, beta- an...

In this study totally 25 rotifer species, 3 cladocerus species, and 2 copepoda species were identified in Ova Stream. Among zooplankton rotifer species were dominant. Population densities of planktonic organisms were calculated as individual per cubic meter and the relationship of the planktonic organisms with physicochemical parameters was determi...

The trophic status of Lake Mogan a shallow, alluvial lake in Central Anatolia, was assessed during a nine-month survey in 1994, including community structure and seasonal distribution of planktonic organisms. Bacillariophyta were dominant among the phytoplankton, followed by Chlorophyta, Cyanophyta, Cryptophyta, Euglenophyta and Dinophyta. Among th...

The seasonal occurrence of medicinal leeches was studied at two lakes in the Black Sea coastland of north-western Turkey. The number of leeches attracted by a collector per hour was taken as an indicator for population density. Leeches were most abundant in May/June, and were almost absent during the cold season (November – March). Leeches with a w...

The Rotifera fauna of ten different lakes in Central Anatolia was studied between April 1998 and October 1999 at monthly intervals. A total of 46 species in 20 genera was recorded, of which Brachionus bidentata, B. leydigii, B. variabilis, Cephalodella plicata, C. gracilis, Elosa worallii, Erignatha sagittoides and Lecane rhenana are new to the Tur...

A survey of all the major potential habitats in western Turkey showed that medicinal leeches, Hirudo medicinalis L., are widely distributed over the country and are not rare. They occur in practically all suitable habitats and the only region where they were found to be absent is that of the large river deltas in the south of the country (ukurova d...

This paper describes the population dynamic parameters of the two cructaceans Diaphanosoma mongolianum, Arctodiaptomus spinosus and four rotifer species which are Filinia longiseta, Hexartra mira, Brachionus angularis and Polyartha vulgaris. …zet: Bu •alÝßmada iki Crustacea Diaphanosoma mongolianum, Arctodiaptomus spinosus ve dšrt rotifera Filinia...

In this study, the abundance and seasonal distribution of rotifer and crustacean zooplankton were examined. A negative correlation beetween rotifers and crustaceans in terms of their abundancy rates was observed. Copepods were most abundant and comprised 43.3 %; rotifers comprised 34 % and cladocerans comprised 22.6% of the total zooplanktonic orga...

Biological and Ecological Investigation of Internationally Wetlands Importan-Sub Project III- Final Report - Salt Lake Basin & Nearby. This project carried our for Republic of Turkey Ministry of Environment, December, 1999.

In this study carbon-length regression was established for Arctodiaptomus bacillifer and lenght-weight relationships were established for Diaphanosoma lacustris, Keratella quadrata and Filinia longiseta, which are abundant in Lake Mogan. Great individual variation was determined in the carbon and nitrogen contents of Arctodiaptomus bacillifer, Furt...
