Ata-Kuh forest, a preserved area within Hyrcanian relict forests, with an area of 700 ha is located in north of Iran. Based on floristic studies from 2011 through 2012, 194 vascular plant species were identified belonging to 143 genera and 66 families. Among our samples, 24 taxa were endemic to Hyrcanian area. The largest families in the area were Rosaceae (10.3 %), Poaceae (9.7 %), Asteraceae ...

The distribution of species richness in families of passerine birds suggests that the net rate of diversification was significantly higher than average in as many as 7 out of 47 families. However, the absence of excess species richness among the 106 tribes within these families indicates that these high rates were transient, perhaps associated in some cases with tectonic movements or dispersal ...

This study was conducted to identify and classify the lichens; determine the diversity index and richness of lichens. A total of 36 species belonging to six genera under three families was identified. Lichen species were mostly found at moderate high altitudinal range with an elevation of 1,131 meters above sea level and open areas where they received adequate sunlight with high moisture and hu...

An annotated checklist of chondrichthyan fishes (sharks, batoids, and chimaeras) occurring in Taiwanese waters is presented. The checklist is the result of a biodiversity workshop held in Mach 2012 as well as on-going systematic revisions by the authors. The chondrichthyan fauna of Taiwan is one of the richest in the world with the number of species totaling 181, comprising 52 families and 98 g...

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...

This communication presents preliminary results of studies on the mite fauna observed in the spruce stands of the Bucegi Massif in central Romania. In the collected material a total of 6436 specimens were found, which were classified to 62 species from 15 families. The most numerous were the species Veigaia nemorensis (1660 individuals), Leptogamasus parvulus (804) and Leptogamasus tectegynellu...

Labiatae family with about 258 genera and 6970 species is one of the biggest families in the world. This family is well represented in Iran having about 45 genera and 363 species which of them 119 species and subspecies are endemic to Iran. Some big genera in Iran are Nepeta (75 species), Stachys (34), Salvia (56), Phlomis (17), Thymus (14). This family is well known for having aromatic essenti...

abstract the syrphidae family with almost 6000 described species, 15 tribes and 3 subfamilies is one of the largest families of diptera. they known as hoverflies or flowerflies. the larvae of subfamily syrphinae are considered the specialized aphidophagous predators play an important role in the reduction of aphid populations in agroecosystems. almost all the adult syrphids feed on pollen or ne...
