considering the importance of biodiversity conservation and protection assessment activities, the present filed study was conducted with aim to compare vegetation diversity of two areas with different levels of protection including ghorkhod protected area with seasonal grazing and golestan national park without grazing, during spring and summer of 2011. four replications were selected in each a...

odonata fauna is poorly known in iran and most of the previous studies deal with northern parts of the country, studying adult specimens. we sampled karun river for aquatic insects in the city of ahvaz in south-west of iran during 2009–2011. as a result, 40 nymphs of one damselfly species and four dragonfly species of the order odonata comprising five genera from four families were recorded. al...

The genus Carex belongs to tribe Cariceae, subfamily Caricoideae and family Cyperaceae. This genus, with about 2000 species in the world and more than 50 species in Iran, is the largest genus among the family. In expedition to North West and West of Iran, two species, namely, Carex acuta and C. cilicica as new records and C. flava, C. rostrata and C. supina as reinvestigated species are reporte...

iran contains 33 named endemic fish species, which together with undescribed taxa, approximates one-third of the ichthyofauna. endemism in relatively large species such as fishes, which are better known systematically than other taxa, can often serve to indicate areas in need conservation. an analysis of endemicity is given in terms of systematics, distribution and ecology.

a new species from iran is described and illustrated here as kickxia iranica (plantaginaceae). kickxia iranica is morphologically similar to k. commutata, a species native to mediterranean region, however it can be distinguished from the latter by leaf shape, color of corolla, habit, stem branching and length of leaf, petiole, pedicel and corolla. notes on its distribution, ecology and phenolog...

the systematics, morphology, distribution, biology, economic importance and conservation of the freshwater eel ( anguilla anguilla ) of iran are described, the species is illustrated, and a bibliography on this fish in iran is provided. the species is found in the caspian sea basin as an exotic.

a survey on the hover flies (diptera: syrphidae) fauna of northern iran, between 2010 and 2011, led to the discovery of the species pipiza accola violovitsh, 1985. both the genus and species are newly recorded from iran. all the specimens were collected from gilan and mazandaran provinces, using malaise traps. the diagnostic characters of p. accola and its geographical distribution is presented.

Polypore fungi are an important group of wood-inhabiting basidiomycetes that have significant roles in biomass recycling in forests and woodland ecosystems. Figures on the polypore diversity in Iran have been partly made available through few checklists, but there have been no comparative studies on the pattern of geographic distribution of the species. The prevalence of the Mediterranean biocl...
