Glechoma L. (Lamiaceae) is distributed in eastern Asia and Europe. Understanding chromosome evolution in Glechoma has been strongly hampered by its small chromosomes, constant karyotype and polyploidy. Here phylogenetic patterns and chromosomal variation in Glechoma species are considered, using genome sizes, chromosome mapping of 5S and 35S rDNAs by fluorescence in situ hybridisation (FISH), a...
Background and Aims Bee orchids (Ophrys) have become the most popular model system for studying reproduction via insect-mediated pseudo-copulation and for exploring the consequent, putatively adaptive, evolutionary radiations. However, despite intensive past research, both the phylogenetic structure and species diversity within the genus remain highly contentious. Here, we integrate next-genera...
Specimens of Paxillus cuprinus, a species recently described from P. involutus complex and characterized by less massive, dully coloured basidiomes with more slender stipes, as well longer basidiospores, were collected authors during an expedition to the Southern Urals (Republic Bashkortostan). The studied collection represents first record in Russia based on basidiomes. identity was confirmed ...
for any lacunary sequence $theta = (k_{r})$, we define the concepts of $s_{theta}-$limit point and $s_{theta}-$cluster point of a sequence of fuzzy numbers $x = (x_{k})$. we introduce the new sets $lambda^{f}_{s_{theta}}(x)$, $gamma^{f}_{s_{theta}}(x)$ and prove some inclusion relaions between these and the sets $lambda^{f}_{s}(x)$, $gamma^{f}_{s}(x)$ introduced in ~cite{ayt:slpsfn} by aytar [...
Phlebiopsis gigantea (Fr.) Jülich is a well-known generalist conifer wood saprobe and biocontrol fungus used in several world countries to prevent stump infection by tree pathogenic Heterobasidion fungal species. Previous studies have reported the presence of regional continental genetic differentiation host-specific fungi, but such for saprobes as P. has not been often studied or demonstrated....
The study of faecal samples to reconstruct the diets and habitats extinct megafauna has traditionally relied on pollen macrofossil analysis. DNA metabarcoding emerged as a valuable tool complement refine these proxies. While published studies have compared results three proxies for sediments, this comparison is currently lacking permafrost preserved mammal faeces. Moreover, most focused single ...
Recent studies indicate that the discriminatory power of the core DNA barcodes (rbcLa + matK) for land plants may have been overestimated since their performance have been tested only on few closely related species. In this study we focused mainly on how the addition of complementary barcodes (nrITS and trnH-psbA) to the core barcodes will affect the performance of the core barcodes in discrimi...
As part of our effort to study wild edible mushrooms from central Mexico. We collected two specimens Cystodermella. Cystodermella mazahuensis is described as a new species This has biocultural importance food for the Mazahua people State Mexico located in Central differs other related by its small cheilocystidia (17–30 × 4–5 μm) and molecular phylogenetic analysis. fourth known genus along with...
background: human fascioliasis is an important health problem in the province of gilan, at the caspian sea, iran. there is the overlapping of both fasciolid species, fasciola hepatica and f. gigantica . recent studies on both domestic animal and lymnaeid infection furnished evidence suggesting that f. gigantica and radix gedrosiana may be the main fasciolid and lymnaeid involved in the dise...
