Yiğitler Deresi’nde (Nif Çayı, İzmir) dağılım gösteren Gammarus izmirensis (Amphipoda) türünün populasyon yapısı
Abstract
Nif Çayı’nın kollarından biri olan Yiğitler Deresi yıl boyu süren düzenli akış rejimine sahiptir. Nispeten kirlenmemiş oluşuyla İzmir ili ve civarının biyolojik çeşitlilik açısından önemli sucul habitatlarından biri konumundadır. Bu çalışma ile tip lokalitesi Yiğitler Deresi olan Gammarus izmirensis Özbek, 2007 türünün populasyon yapısı hakkında bilgi sahibi olunması amaçlanmıştır. Tür hakkında orijinal tanımının yapıldığı çalışma dışında herhangi bir bilgi bulunmamaktadır. Gammarus bireyleri Ekim 2015-Eylül 2016 döneminde yapılan aylık örneklemelerle toplanmıştır. Örneklemeler tek bir lokaliteden yapılmıştır. Çalışmada 1938 adet G. izmirensis bireyi incelenmiş olup, bunların 850 adedi dişi, 586 adedi erkek ve 502 adedi de juvenil bireylerden oluşmaktadır. Erkek bireylerde maksimum vücut boyu 14,5 mm, dişi bireylerde ise 14,0 mm olarak ölçülmüştür. Jüvenil bireylerin Mart ve Ağustos aylarında daha fazla görüldükleri dikkati çekmektedir. Bu türün, ilkbahar ve yaz olmak üzere, yıl içinde birden fazla kez ürediği tespit edilmiştir.

Population structure of Gammarus izmirensis (Amphipoda) inhabiting Yiğitler Brook (Nif Stream, İzmir)
Abstract
Yiğitler Brook, one of the branches of Nif Stream, has a regular flow regime throughout the year. The brook is one of the important aquatic habitats in terms of biological diversity by having relatively unpolluted water. The main objective of the present study is to get information about the population structure of Gammarus izmirensis Özbek, 2007 whose type locality is Yiğitler Brook. There is no information about the species in literature except its original description paper. Gammarus specimens were sampled in monthly intervals between October 2015 and November 2016. Samplings were performed at one locality. During the study, a total of 1938 G. izmirensis specimens were investigated. Of them; 850 were females, 586 were males and 502 were juveniles. The maximum body length was 14.5 mm in males and 14.0 mm in females. The number of juveniles is higher in March and August. The species has a multivoltine life cycle with two generations (spring and summer) throughout the year.
