    The aim of this study was to investigate body shape variations of Alosa braschnikowi populations in three localities of the Caspian Sea using geometric morphometric method. So that, 216 specimens were caught from three regions from west to east, including Guilan (Anzali), Mazandaran (Sari) and Golestan (Miankaleh). Shape data was extracted using 15 landmark points on 2-D pictures of specimens. The PCA, DFA analyses and cluster analysis based on Euclidean square distances were used to examine shape differences among the three populations. The results showed that there was a significant difference between the studied populations in terms of body shape (p<0.05). The population in Guilan had a longer head and snout, short and depth caudal peduncle and longer dorsal fin base that was different from the populations in Mazandaran and Golestan regions. Differences in head and snout shapes of the Guilan population with other populations, can be considered as a reflect of differences in feeding resources and selection of food items. Body shape differences may also be due to geographical distance and other environmental parameters. Specifications obtained on the basis of the body shape of A. braschnikowi can provide an identification key that is useful to distinguish species.

    This study aimed to find new species of cephalopods in the Iranian waters of the Gulf of Oman. Two species of Oegopsida (Abralia steindachneri Weindl, 1912 and Joubiniteuthis portieri (Joubin, 1916)) and also one species of Sepiida (Sepia omani Adam & Rees, 1966) were identified. Samples were collected in March and April 2019, using a Myctophidae trawler. To capture A. steindachneri a two-panel bottom trawl (codend mesh size (A) equal to 60 mm) was used, while for J. portieri and S. omani a four-panel midwater rope trawl (codend mesh size (A) equal to 90 mm) was applied. Taxonomic studied on these rare cephalopods, in this region, would be helpful for protecting their stocks as well as safely exploitation them.

    Ongoing investigation into Chironomidae specimens collected from the Sirwan River watershed in 2020 resulted in two new faunistic records for Iran, and new range extensions for the Palearctic region. Two species, Paramerina divisa (Walker, 1856) and Xenochironomus xenolabis (Kieffer, 1916) are diagnosed and reported for the first time from Iran. This contributes to establishing baseline data about the diversity and distribution of freshwater flora and fauna of this region.

    Brittle stars are one of the most diverse classes of echinoderms distributed worldwide in marine habitats. In this study, brittle stars were sampled by hand from the intertidal zone of the Persian Gulf's western part to the Oman Sea, from locations accessible without the need of a boat or diving equipment. Sampling time was set in the first days of the lunar month or at least the time of the lowest tide in each day. The specimens were first immobilized in freshwater, then fixed in neutralized buffered formalin, and finally preserved in 70% ethanol after one week of fixation. Of 22 sampling points, seven localities yielded intertidal brittle stars (Macrophiothrix hirsuta cheneyi, Macrophiothrix elongata, and Ophiocoma scolopendrina) during the sampling period (December 2017–March 2018). Ophiocoma scolopendrina is reported for the first time from Dayyer and Nayband in the Persian Gulf. We also re-evaluated recently reported data on ophiuroids from the studied area.

    In this paper a batch of earthworms from Afghanistan was studied and previous reports on the earthworm fauna of the country were evaluated. In the present study, earthworms were collected by digging and hand sorting, and fixed in 80% ethanol. Six species belonging to three families were identified. They are Aporrectodea caliginosa, Ap. rosea, Eiseniella tetraedra, Drawida annandalei, Amynthas corticis, and Metaphire bahli. Among them A. corticis, Ap. caliginosa, D. annandalei, and M. bahli are new records for the country. Nine species have previously been reported from Afghanistan of which two were collected in the current survey as well. Therefore, this study in Afghanistan increased the number of earthworm species registered for the country from 9 to 13 belonging to nine genera and three families. Out of the 13 species, 10 (Ap. caliginosa, Ap. jassyensis, Ap. trapezoides, Ap. rosea, Bimastus parvus, Dendrobaena byblica, D. fedtschenkoi, Eisenia fetida, Eis. tetraedra, and Lumbricus rubellus) belong to the Holarctic family Lumbricidae, two species (M. bahli and A. corticis) to the family Megascolecidae, and one species (D. annandalei) to Moniligastridae. Most of the species (10) are peregrine and only three of the lumbricid species in Afghanistan are regarded as autochthonous, viz., Ap. jassyensis, D. byblica, and D. fedtschenkoi. The diversity and distribution of earthworms in Afghanistan is far from complete. To fill this gap in our knowledge on the earthworm fauna of the studied region more detailed investigations are needed to explore the earthworm fauna of this vast country.

    Biodiversity is one of the key components of environmental sustainability and its conservation is very important. To conserve biodiversity, both its management and measurement management are necessary. Biodiversity measurement means some quantitative value that can be ascribed to the various measurements so these values can be compared. With its geographic and climatic variety, Iran has a valuable biodiversity, which includes about 1,130 and 8,000 species of vertebrates and flora, respectively. Due to the large amount of data (occurrence points) and complexity of calculations, utilizing computer programs is essential. Though numerous software have been developed in this field, Iran has no exclusive software. Therefore, we here present BDI v. 1.0.0 (BioDiversity of Iran), a user-friendly software utility which facilitates the calculation of the most commonly used biodiversity indices and then spatially visualizes the results on a map with high precision and resolution.

    The Leaf-toed Geckos of genus Asaccus are distributed in Turkey, Syria, Iraq, and Iran of the Middle-East characterizing by a unique characteristic of cloacal sacs and postanal bones absence. The genus Asaccus includes 19 species with at least 10 species in Iran distributing along the Zagros Mountains. Sexual size dimorphism (SSD) is a body size difference between males and females of the same species, being a widespread phenomenon in reptiles. We collected additional specimens of Asaccus nasrullahi (Phyllodactylidae) from four new localities in Ilam and Khuzestan Provinces, western Iran. In this study, 110 adult specimens of this lizard were examined (for nine metric and four meristic characters). The analyses of morphological data revealed that the males are significantly larger than the females in eight metric characters including forelimb to hind limb length (FHL), length of forelimb (LFL), length of hind limb (LHL), head height (HH), head length (HL), head width (HW), rostrum to anus length (RAL), and tail length (TL). There is no significant difference in the rate of tail shedding between the sexes. The range of this species is extended beyond type locality in Lorestan Province into adjacent areas in Ilam and Khuzestan Provinces.

    To compare body shape variations and meristic plasticity among four populations of Alburnoides idignensis fish from Aab-barik, Aab-Sardeh, Darband and Sarab-e Kayvareh rivers in Tigris River Drainage, Persian Gulf Basin of Iran. Geometric morphometric method was used to compare shape data extracted by recording 15 landmark points on 2-D pictures of 94 specimens collected from the rivers by electrofishing and a seine net. The Principal component analysis, Canonical Variate analysis and MANOVA analysis were used to examine shape differences among the populations. Eight meristic traits including number of lateral line scales (LL), scales above and below LL to ventral fin, pre-dorsal scales, dorsal, anal, pectoral and pelvic branched rays were counted under a stereomicroscope and mean number of the data were compared by Kruskal–Wallis and ANOVA in SPSS software. Significant differences were found among the four populations in all meristic traits but the number of LL scales and in their body shape, separating them from each other. Results revealed that the studied populations have some differences in meristic characters and in the shape and size of the head, body, caudal peduncle and ventral and anal fin position.

    Rich avifauna of Fars province, SW Iran, is a stem from high diversity of habitat and climate beside its geographical position as a crossroad between Palearctic, Oriental, and Afrotropical realms. It shares the greatest number of bird species with the Palearctic region, however two other faunal realms, including Oriental and Afrotropical have a pronounced influence on its avifauna. It seems its bird fauna to be more in common with the Oriental elements than Afrotropical ones; the question addressed in this study. In addition, the province is located east of the Western Palearctic and close to the Eastern Palearctic border. I explored how much its bird elements have in common with the Eastern Palearctic. It is important because in some cases, western and eastern bird elements may come together with a narrow or wide hybrid zone. Based on my expeditions in recent years and pervious published literature, I present the comprehensive annotated checklist including 371 bird species in 197 genera, 68 families and 23 orders. At least 88 species are resident, 193 species are breeding, 33 species are rare and 21 species are vagrant. Based on the international conservation criteria, five species fall under the EN, nine under the VU, 16 under the NT of IUCN and 62 species fall under the appendices of CITES, including eight species in appendix I and 54 in appendix II. Results show that the Fars province shares the greatest number of bird species with the Palearctic region (364). The province lies within the West Palearctic faunal region and as expected, its bird fauna shares a greater number of species with the western Palaearctic than its eastern (346 versus 314). Our results also showed that the two other adjacent faunal regions including Oriental and Afrotropical have influence on its avifauna, and the province shares a greater number of species with the Oriental than to Afrotropical.
