The study investigated nematode diversity in three contrasting habitat types around the Yeniçağa Lake, Bolu Province, Turkey, in 2019 and 2020. The Shannon-Wiener index was used to evaluate nematode diversity in different taxonomic categories (order, family and genus level), trophic group and colonizer-persister (c-p) group in grassland, cropland and peatland in two locations, Hamzabey and Adaköy, in the Yeniçağa Lake Reserve. The results revealed that there was statistically significant variation in the composition of nematode fauna between the study sites by the assessments of the higher taxa whereas genus level and family level lower taxa did not differentiate such variation in Hamzabey and Adaköy. In addition, the variation in nematode diversity in relation to soil types were better reflected by assessing the trophic group structures rather than the c-p groups. The findings indicated that the diversity at higher taxa might serve as a better indicator than the diversity of lower taxa (family and genera) variation among the habitat types of the study areas.

Çalışma, 2019 ve 2020 yıllarında Bolu İli’ndeki Yeniçağa Gölü çevresinde üç farklı habitat tipi altında nematod çeşitliliğini incelemiştir. Shannon-Wiener indeksi, Yeniçağa Gölü rezerv alanındaki Hamzabey ve Adaköy lokasyonlarında otlak, tarım arazisi ve turbalık alanlardan üç arazi tipinde farklı taksonomik kategorileri (takım, familya ve cins seviyesi), trofik grup ve kolonizör-persister (c-p) grupları ve nematod çeşitliliğini değerlendirmek için kullanılmıştır. Sonuçlara göre, çalışma sahaları arasında nematod fauna kompozisyonunda, takım seviyesindeki taksonlarda istatistiksel olarak önemli farklılıklar olduğunu, cins seviyesi ve familya seviyesindeki düşük taksonlarda ise Hamzabey ve Adaköy'deki varyasyonları ayırt etmede daha zayıf kaldığı görülmüştür. Ayrıca, toprak tiplerine göre nematod çeşitliliğindeki varyasyonlar, c-p grupları yerine trofik grup yapıları değerlendirildiğinde daha iyi sonuçlar alınmıştır. Bulgular, yüksek taksonlardaki çeşitliliğin daha düşük taksonlara (familya ve cins) göre, çalışma alanındaki habitatlar arası farkın ayırımında daha iyi bir gösterge olabileceğini ortaya koymuştur.
