In order to evaluate the macrozoobenthic fauna of Çıldır, Aktaş and Aygır lakes, 47 taxa were identified as a result samplings carried out in different periods 2013, 2017 2019. 41 43 at species level new records for study area. The dominant Lake Çıldır Gyraulus (Armiger) crista (4.49%), Paratanytarsus lauterborni (3.90%) Virgotanytarsus arduensis (3.80%). It was seen that gammarid population de...

The purpose of this study was to investigate the distribution and biodiversity of diatoms during different seasons and their correlation with water quality parameters in Helleh River estuary, Bushehr, Persian Gulf. Samples were taken in mid-season from summer 2011 to spring 2012 during a one-year period from different stations. Results showed that diatoms mostly comprised of Bacillariophyceae, ...

Yang and Qiu proposed and then recently improved an expected utility-entropy (EU-E) measure of risk and decision model. When segregation holds, Luce et al. derived an expected utility term, plus a constant multiplies the Shannon entropy as the representation of risky choices, further demonstrating the reasonability of the EU-E decision model. In this paper, we apply the EU-E decision model to s...

The study was carried out to compare the biodiversity parameters of insect species in natural and un-natural habitats Gölcük Nature Park (Isparta Province) between 2018 2019. Two two unnatural (impact tourism) were selected realize mentioned aim. Totally 40 pitfall traps (10 for each habitat) set up sample Coleoptera species. Species richness found higher than ones. Diversity index (both Shanno...

The phenotypic diversity of about 200 bacterial strains isolated from soil was compared with the genotypic diversity of the same population. The strains were phenotypically characterized by the API 20B test system. The results of these tests were subjected to cluster analysis, which revealed 41 biotypes at 80% similarity. The five dominating biotypes contained 43% of the strains. The phenotypic...

The paper studies edge-coloring of signed multigraphs and extends classical Theorems Shannon K\"onig to multigraphs. We prove that the chromatic index a multigraph $(G,\sigma_G)$ is at most $\lfloor \frac{3}{2} \Delta(G) \rfloor$. Furthermore, balanced $(H,\sigma_H)$ $\Delta(H) + 1$ with $\Delta(H)$ are characterized.
