First record of micrasema cinereum mosely (trichoptera, brachycentridae) in Turkey and a list of the caddisfly fauna in Arac Creek
Systematic studies on Trichoptera larvae in Turkey are very limited. The larval stage of the endemic species remains
especially unknown. This study was carried out in Araç Creek between April and October 2013 and it is the first study to
determine the caddisfly fauna in Araç Creek. Fourteen caddisflies taxa belonging to nine genera within eight different families
(Brachycentridae, Hydropsychidae, Hydroptilidae, Lepidostomatidae, Leptoceridae, Limnephilidae, Psychomyiidae and
Rhyacophilidae) were identified. Four of these taxa have previously been recorded from the creek and the other ten taxa are
new records for the study area while Micrasema cinereum Mosely is the first record for the Trichoptera fauna of Turkey. As a
result of the study, the number of caddisfly taxa in Turkey is now 501, with the addition of M. cinereum.Türkiye’de Trichoptera larvaları üzerindeki sistematik çalışmalar çok sınırlıdır ve özellikle endemik türlerin larva evresi

The aquatic oligochaetes (Annelida: Clitellata) of eight lakes in the A¸sa˘gı Fırat River Basin (Lower Euphrates, Turkey)
The A¸sa˘gı Fırat River is located in the south-eastern Anatolia, Turkey. The water quality of the A¸sa˘gı Fırat River
basin has been degrading for some time, primarily as the result of pollutants associated with the discharges from numerous
domestic and agricultural point sources. Aquatic macroinvertebrate samples were collected from eight lakes conducted by
using both hand-nets and an Ekman-Birge grab sampler during the summer and autumn of 2014, focusing on the species
composition and distribution of aquatic oligochaetes in eight lakes of the A¸sa˘gı Fırat River basin, and their relationships
with physico-chemical parameters measured in those lakes using Principal Component Analysis. Results of analyses of all
identified benthic macroinvertebrates clearly indicate the percent dominance of oligochaetes in benthic samples in the eight
dam lakes that were sampled: Hacıhıdır lake (62.9%); Atat¨urk lake (49.6%); ¨U¸c¨oz lake (28.9%); Dumluca lake (22.01%);
Seve lake (13.9%); C¸ at lake (8.5%); Karakaya lake (7.8%) and Birecik lake (5%). During this study, 1044 oligochaete
specimens representing 10 species of two subfamilies within the family Naididae were identified. The most abundant taxa
were Limnodrilus hoffmeisteri (48.94%), Potamothrix hammoniensis (19.3%), Tubifex tubifex (13.1%), Nais simplex (5.2%)
and Nais communis (4.1%).This study was supported by the Ministry of Forestry and

Metal concentrations in surface sediments of beyler reservoir (Turkey)
The accumulation of metals (Iron, Aluminium,
Zinc, Copper, Manganese, Boron, Chromium, Nickel, Cadmium,
Lead) was seasonally (November 2009 to July 2010)
measured in sediment samples taken from different areas of
Beyler reservoir which is an important water source for
irrigation in West Black Sea region (Turkey). Metals in
sediment samples were analyzed by ICP-OES. The difference
between the stations except for Zn metal (p\0.05) has
not been considered as important and a statistical difference
between seasons for Fe, Ni metals (p\0.01) and Cu metal
(p\0.05) has been observed. The magnitude of metal
concentrations in sediment was determined as Aluminium[
Iron[Manganese[Zinc[Chromium[Copper[
Boron[Nickel[Lead[Cadmium. Enrichment factor
(EF) for all metals has been calculated (EF\1). In the
evaluation done by considering the EF values, it is seen that
the metal concentrations found in the Beyler Dam Lake
sediment stem from the natural composition of the sediment.The authors are grateful for the financial support

Assessment of concentration physicochemical parameters and heavy metals in Kızılırmak River, Turkey
Kızılırmak is the longest river of Turkey and the most important one as a resource for various water
uses. Therefore Kızılırmak river basin is under pressure from a diverse range of human activities.
Six stations were sampled along the Kızılırmak river located in Nevsehir city during 2013–2014 seasonally.
The physico-chemical parameters (water temperature, biological oxygen demand (BOD),
chemical oxygen demand (COD), pH, dissolved oxygen (DO), conductivity, nitrite (NO3), ammonium
(NH4), ammonia (NH3), phosphate (PO4), sulfate (SO4) and some metal concentrations (Zn, Cu,
B, Cr, Ni, Pb, Hg, As, Se, Sb, Mn, Cd and Al) were measured in the water samples to determine the
water quality of the Kızılırmak river. When the water quality classes were examined in terms of the
measured physico-chemical parameters, it was detected that the river is IV. class for nitrite, III. class for BOD, phosphate and pH, II. class for NH4–N. The results showed that the heavy metal concentrations in water of the Kızılırmak river were within the quality class I. limits of the EPA and WPCR.The authors wish to thank to NevsehirHaciBektasVeli University, Scientific Research Project Fund (NEUBAP) for their financial support [Project number: NEUBAP13F22]
An assessment of metal pollution in surface sediments of Seyhan dam by using enrichment factor, geoaccumulation index and statistical analyses
The aim of this study was to determine if
high concentrations of any heavy metals exist in the
sediment of Seyhan Dam reservoir to be considered
toxic to the aquatic environment. Surface sediment
samples from five stations in the Seyhan dam were
collected quarterly from 2004 to 2005 and examined
for metal content (Cr, Zn Cu, Mn, Cd, Fe, Ca, K, and
Na), organic matter, and grain size. Correlation
analyses showed that metal content of Seyhan dam
sediment was affected by organic matter and grain size.
The results have been compared with values given in
the literature. The evaluation of the metal pollution
status of the dam was carried out by using the
enrichment factor and the geoaccumulation index. A
comparison with sediment quality guideline values has
also been made. Based on the enrichment factor, dam
sediments were treated as a moderately severe enrichment
with Cd and minor enrichment with Cr and Mn.
The results of geoaccumulation index reveal that
sediments of Seyhan Dam were strongly polluted in
stations 1, 2, 4, and 5, and were moderately polluted in
station 3 with Cd. Moreover, Cd and Cr concentrations
in the sediments were above TECs except ERL for Cd.This work was supported (SÜF 2004

Aquatic oligochaetes (Annelida: Clitellata) of seven lakes in the Ceyhan River basin (Turkey)
Oligochaeta samples were collected from seven lakes (2 natural and 5 non-natural) of Ceyhan River basin during
the summer and autumn seasons of 2014. The Ceyhan River basin is located in the south-eastern Anatolia region in Turkey.
Lakes G¨olba¸sı and Azaplı are located in a protected area. Some physico-chemical parameters of surface water were measured
in situ. Sampling for oligochaetes was conducted by using both hand-nets and an Ekman Birge grab sampler, with samples
obtained from different depths. Oligochaetes represented the dominant group of the total benthic macroinvertebrates in
samples, with the exception of samples collected from Ayvalı Dam lake. A total of 11,293 oligochaete specimens were sorted
from samples collected from these lakes, from which 14 species belonging to 2 subfamilies (Naidinae and Tubificinae) were
identified. Potamothrix hammoniensis (90.24%) and Limnodrilus hoffmeisteri (7%) were the most abundant oligochaetes in
the samples.This study was supported by the Ministry of Forestry and
