Littoral (lake shore) macroinvertebrate communities were studied in eight natural lakes affected by fallout from the Chernobyl accident. The lakes spanned a range in (137)Cs contamination from 100 to 15500 kBq m(-2) and estimated external dose rates ranged from 0.13 to 30.7 μGy h(-1). General linear models were used to assess whether abundance of individuals, taxon richness, Berger-Parker domin...

This study was carried out to determine the biodiversity and densities of Trichoptera larvae at stations in Kastamonu (Cide)-Sinop (Ayanc?k) coastal region. Benthic macroinvertebrate samples were collected from each 19 using kick-net sampling method with a D-frame net (500-?m mesh). Using data larvae, similarity, diversity, dominance population density relationships among habitats measured. Acc...

This study was carried out to compare the biodiversity parameters of epigean insect species in 3 different regions with geographical conditions. Tefenni Plain, Beyköy (Abdülmelik) Plain and Çaylı Mountain Village, which are located at altitudes, were chosen as area. Pitfall traps placed agro-ecosystems anise fennel each region caught pitfall checked weekly. A total 2086 individuals belonging 11...

This study investigated the biodiversity, phylogeny, and antifungal activity of endophytic fungi isolated from Zanthoxylum bungeanum. A total of 940 isolates obtained were grouped into 93 morphotypes, 43 species, and 23 genera, which were authenticated by molecular identification based on rDNA internal transcribed spacer (ITS) sequence analysis. A high diversity of endophytic fungi from Z. bung...

Conserving aquatic ecosystems requires efficient tools to accurately assess the biodiversity of species. However, existing knowledge is insufficient in terms reliability and comparability methods measuring fish diversity. Environmental DNA (eDNA), as a promising method, was used detect taxa this study. We optimized eDNA method laboratory, applied optimal survey diversity natural life reserve. s...

Biodiversity assessment of tropical taxa is hampered by their tremendous richness, which leads to large numbers of singletons and incomplete inventories in survey studies. Species estimators can be used for assessment of alpha diversity, but calculation of beta diversity is hampered by pseudo-turnover of species in undersampled plots. To assess the impact of unseen species, we investigated diff...

High concentrations of heavy metals have been shown to adversely affect the size, diversity, and activity of microbial populations in soil. The aim of this work was to determine how the diversity of arbuscular mycorrhizal (AM) fungi is affected by the addition of sewage-amended sludge containing heavy metals in a long-term experiment. Due to the reduced number of indigenous AM fungal (AMF) prop...

Entropies such as the Shannon /Wiener and Gini /Simpson indices are not themselves diversities. Conversion of these to effective number of species is the key to a unified and intuitive interpretation of diversity. Effective numbers of species derived from standard diversity indices share a common set of intuitive mathematical properties and behave as one would expect of a diversity, while raw i...

We examined the density, diversity, and seasonal fluctuation of soil inhabiting Collembola in different ecosystems: agricultural, rangeland, forest ecosystems North Khorasan province Iran from June 2018 to May 2019. The sampling program was conducted monthly on three sites. Density measured number individuals per square meter. Species diversity calculated using Shannon?Wiener index, Simpson?s s...
