Investigations on soil nematode diversity in three contrasting habitat types in Bolu, Turkey (original) (raw)

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.
