based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
The Spring season in Iran, especially the months of April and May, is a thriving season for the wild harvesting and sale of fresh medicinal plants and mushrooms that are seen in the form of local markets and seasonal stores during the rainy season. Based on habitats of Iranian truffles, they can be classified in two groups including Desert truffles and Forest truffles. Based on our knowledge de...
The aim of this study was the identification of morphometric and meristic characters and their diversity between males and females of Alburnus chalcoides in southern coast of the Caspian Sea in 2019. 160 specimens were caught randomly in 8 rivers leading to the Caspian Sea on the coast of Gilan (Anzali Wetland, Sefidrood River Basin, Allah Rud) and Mazandaran (Chalkroud, Cheshmeh Kileh, Mianrou...
In this study, the phylogeny and morphological variation of 6 species of the genus Cousinia sect. Stenocephalae, i.e., C. hypopolia, C. decipiens, C. esfandiarii, C. renominata, C. stahliana and C. daryoushiana, distributed in NE regions of Iran, were investigated. ITS, ETS and rpl32-trnL (UAG) sequences for 12 species (17 specimens) were generated. Phylogenetic interspecies relationships were ...
This study was conducted in the Kordofan region of Sudan during 2011–12. It was devoted to the morphology associated to the juvenile development and performance of tree species of Capparaceae and Combretaceae in a nursery and early field growth. The nursery experiment was conducted to study morphological characters to identify seedlings of tree species under study. Seedlings were transplanted t...
six belonolaim species were collected from grasslands of sabalan region. the found species belong to genera amplimerlinius, merlinius, nagelus, neodolichorhynchus, paramerlinius and tylenchorhynchus. among the found species, neodolichorhynchus judithae is reported for the first time from iran and is characterized byhaving offset head, cuticule with 16 longitudinal ridges, delicate stylet 21-23 ...
Many questions in evolutionary biology are best addressed by comparing traits in different species. Often such studies involve mapping characters on phylogenetic trees. Mapping characters on trees allows the nature, number, and timing of the transformations to be identified. The parsimony method is the only method available for mapping morphological characters on phylogenies. Although the parsi...
Acoustic and morphological characters are very important to distinguish species of Cicadidae. In this study, the morphological and acoustic characters of Cicadatra platyptera Fieber, 1876 (Hemiptera, Cicadidae) collected from Turkey were analysed. The external morphological structures of two species were drawn and photographs of some specimens were taken. We evaluated taxonomically important mo...
In order to estimate the heritability of morphological characters of worker honey bee and honey yield, 30 queen-mothers were selected randomly from the apiary of Research Center of Animal Science and Natural Resources in Isfahan Province. From each queen-mother, five queen-daughters were reared and introduced to equalize colonies after natural mating of queens. Summer honey yield was measured, ...
