In this study, the epiphytic algae of Lemna minor collected from its natural habitat or grown in aquarium were analyzed for a period of six months from April 2016 to September 2016. While a total of 15 taxa, 1 belonging to Cyanophyta and 14 belonging to Bacillariophyta, were recorded for L. minor grown in aquarium, a total of 36 taxa, 3 belonging to Cyanophyta, 5 belonging to Chlorophyta, 1 bel...

Arasbaran protected area is located in NW Iran, is one of nine designated Biosphere Reserves in Iran. According to the literatures and the current study, 1067 plant taxa are identified in the area. Eighteen plant taxa of the area are endemic to Iran. Hemicryptophytes (42.5 %) are the most frequent life forms in the reserve followed by therophytes (25.8 %), cryptophytes (18.8 %), phanerophytes (...

Most supertree algorithms combine collections of rooted phylogenetic trees with overlapping leaf sets into a single rooted phylogenetic tree. It is implicit in all these algorithms that the leaves of the rooted phylogenetic trees in the input collection, as a whole, represent non-nested taxa. Thus, for example, the “domestic dog” and “mammal” cannot be represented by two distinct leaves in such...

Cyanobacteria represent a small taxonomic group of photosynthetic prokaryotes which some of them are capable of N2 fixation and also possess a tremendous potential for producing a wide range of secondary metabolites. It has been suggested that, some of these microorganisms, especially heterocystous cyanobacteria, assist higher plant growth by supplying growth stimulating substances. During a fl...

A phenetic analysis of the 12 taxa or operational taxonomic units (OTUs) belonging to the three sections; Genea, Neobromus, and Nevskiella of the genus Bromus was performed. Unweighted pair-group method using arithmetic averages (UPGMA) and weighted pair-group method using arithmetic averages (WPGMA) clustering and factoriel method analyses were used to set the taxa apart. Forty-four characters...

In the framework of study on wood inhabiting Hyphomycetes in Gilan province, Iran, during 2002- 2003 eighteen taxa belonging to different genera were identified as follows: Chloridium botryoideum, Dendryphiopsis atra, Epicoccum nigrum, Periconia minutissima, Periconia byssoides, Periconia sp., Phaeoisaria clematidis, Pseudospiropes simplex, Sporidesmium adscendens, Sporidesmium brachypus, Spori...

This paper is in line with the previous publication on the wood inhabiting Hyphomycetes from Gilan province (Iran). As a results, 22 taxa were identified which are listed as follows: Arthrinium state of Apiospora montagnei, Arthrinium saccharicola, Arthrobotrys sp., Berkleasmium sp., Clonostachys rosea, Cryptocoryneum sp., Cylindrocladium colhonii, Dendrostilbella sp., Dendryphion comosum, Endo...
