In this study, the epiphytic bryophyte vegetation of Fagus orientalis forests in Hıdırnebi Plateau (Trabzon, Turkey) was investigated. A total 34 relevés taken from living tree trunks different periods 2020 were analysed according to Braun-Blanquet methodology. As a result analyses, Leskeello nervosae–Pterigynandretum filiformis, filiformis lewinskyetosum rupestris subass. nov., Pseudoleskeello...

In view of the current situation shortage alkaline aggregate and abundance weakly acidic weathered igneous rocks around Nairobi, Kenya, in order to fully improve adhesion performance asphalt rocks, this paper studies effects different anti-stripping agents separately combined on aggregates. The results show that agent can property medium rock asphalt, effect is better when combined.

Radiative lifetimes, accurate to 5%, have been measured for 58 odd-parity levels of Pt i using laser-induced fluorescence. The lifetimes were combined with branching fractions measured using grating and Fourier transform spectrometry to determine transition probabilities for 127 lines of Pt i. The new Pt lifetime measurements were found to be in good agreement with previous but less extensive m...

The study of 5-hydroxylmethylcytosines (5hmC) has been hampered by the lack of a method to map it at single-base resolution on a genome-wide scale. Affinity purification-based methods cannot precisely locate 5hmC nor accurately determine its relative abundance at each modified site. We here present a genome-wide approach, Tet-assisted bisulfite sequencing (TAB-Seq), that when combined with trad...

Lepidopterists have long acknowledged that many uncommon butterfly species can be extremely abundant in suitable locations. If this is generally true, it contradicts the general macroecological pattern of the positive interspecific relationship between abundance and distribution, i.e. locally abundant species are often geographically more widespread than locally rare species. Indeed, a negative...

To determine the composition and abundance of zooplankton assemblages in Eğirdir Lake-Turkey, monthly surveys were conducted from January to December 2010 at four stations. A total of 65 major zooplankton species were identified. Rotifera was the most abundant taxon dominated mainly by the species Polyarthra dolichoptera and Keratella cochlearis. Rotifers were recorded at the maximum abundance ...

We have studied the REE distribution in shallow marine continental platform carbonates belonging to two late Neoproterozoic basins of India. Their REE abundance patterns normalized by chondrite display well defined W-type tetrad effect. Based on chondrite-normalized Gd/Ho, La/Nd ratios, the REE abundance patterns have been classified into three groups. (Y/Ho) and (Y/Dy) concentration ratios ref...

To address the combined effects of cadmium (Cd) and elevated CO2 on soil microbial communities, DGGE (denaturing gradient gel electrophoresis) profiles, respiration, carbon (C) and nitrogen (N) concentrations, loessial soils were exposed to four levels of Cd, i.e., 0 (Cd0), 1.5 (Cd1.5), 3.0 (Cd3.0) and 6.0 (Cd6.0) mg Cd kg(-1) soil, and two levels of CO2, i.e., 360 (aCO2) and 480 (eCO2) ppm. Co...

changes in abundance and biomass of cyanobacteria have been studied in the southern part of the caspian sea (the stretch between tonekabon and amirabad) in four seasons (spring, summer, autumn, winter) in which samples were taken from five depths of 5, 10, 20, 50 and 100 meters in the stations of tonekabon, noushahr, babolsar and amirabad. samples were fixed in formalin (2-2.5%) before transfer...
