In this study, we explore Dehram river system, focusing on its biological characteristics, in a hot arid region. This is a freshwater stream flowing over salt formations. We examined various ecological aspects of the river, including its benthic macroinvertebrates, zooplankton, fishes, as well as some physical and chemical factors in three selected stations. The river showed variations in physical and chemical properties, with salinity and conductivity levels being the most significant. Salinity, total dissolved solids, calcium ion concentration, and nitrate levels increased downstream in the study area. Our findings revealed 13 macroinvertebrate orders present in the river, including a new record for Fars Province - the hydrobiid gastropod Ecrobia grimmi. The discovery of the four fish species in the river marked a new addition to their known geographical distribution. Certain invertebrate families were unique to station 1 and/or 2, while families Dyticidae and Simuliidae were exclusive to station 3. Other families were found in all three stations. Fish groups in the river included four identified cyprinid species, revealing new distribution ranges for them. Capoeta barroisi, known for tolerating specific environmental conditions, was found to adapt to the higher temperature, EC, and pH ranges in the river, setting new ecological records. The river exhibited unique ecological conditions such as high temperature and extranormal conductivity levels, which may have led to specific adaptations in its biota. We recommend further detailed investigations to determine whether these are new species or highly adapted populations isolated geographically and physiologically.

The water resource provided by lake basins in the western desert of Iraq is important for human occupation of areas outside the Tigris-Euphrates floodplain, both in the past and into the future. This paper presents the first geomorphological and geochro-nological study of the date of formation of the Najaf Sea and the only such study of any lake basin to the west of Mesopotamia. Geomorphological shoreline features and a palaeochannel linking to the Euphrates were studied and dated using optically stimulated luminescence (OSL) and radiocarbon dating. Provenance was determined using heavy mineral analysis. Past environments in the Najaf Sea were reconstructed by molluscan analysis. The earliest OSL ages date from c. 30 000 and 22 000 years ago and seem to predate lake formation. Younger OSL ages date the highest lake level at c. 19 m asl to between 1620-1760 AD (base) to 1906-1974 AD (near surface). The radiocarbon ages are affected by a freshwater reservoir effect, but the maximum ages recorded for either of the c. 15 m and c. 17 m asl shorelines are c. 800 cal. BC. This predates the first archaeological sites in the Najaf basin and is similar to maximum ages of c. 850 and c. 1100 cal. BC from the associated pal-aeochannel. This timing does not seem to be linked to a humid climate event. We therefore conclude that the establishment of the Najaf Sea in the Najaf basin occurred as a result of an avulsion event within the Euphrates system that diverted flow to the basin. The trigger for this avulsion event likely related to rapid sediment accumulation and may have been either autogenic or driven by human activity. This study therefore suggests that Najaf Sea formation facilitated human expansion beyond the Tigris-Euphrates floodplain and occurred due to avulsion of the Euphrates.

The distribution of the recent Lymnaeidae across continents and zoogeographical regions of the world is reviewed, with a brief characteristic of the geographical distribution of each extant lymnaeid genus. The quantitative estimates of the similarity between the lymnaeid faunas of different continents and the largest zoogeographical regions are provided and discussed. It is shown that the highest taxonomic level of endemism in the family is observed in the Nearctic region, and the overall faunal similarity is highest among the Palaearctic and Oriental region, whereas the Australian fauna is the most peculiar. A special section of the article is devoted to a review of the invasive lymnaeid species and the possible consequences of their invasions to the non-native areas.
... Nevertheless, F. bengalensis is also present outside India, towards the Middle East, including Afghanistan, Iran, Iraq and Pakistan ( Glöer, 2019 ), but not on the Arabian Peninsula ( Neubert, 1998 ). There are several reports from the Khuzestan and Mazandaran Provinces in Iran (see Glöer & Peši ć, 2012 and references therein), but the first known record in this region is from Basra in Iraq ( Pallary, 1939 ), which is probably the species' westernmost extension. In the recent literature, F. bengalensis is mostly used as a bioindicator species for pollution in several places across the Mesopotamian Plain (e.g. ...
In the present study, we genetically analyse populations of ' Filopaludina bengalensis' from the Euphrates River (Iraq), more than 4,000 km from its type locality. By sequencing several mitochondrial and nuclear genes, we aimed to test whether this population indeed belongs to F. bengalensis from India and how it is related to other members of the genus. Our molecular phylogeny shows that the individuals from Iraq form a mono-phyletic group together with other populations of F. bengalensis from India and F. doliaris from Indochina. The haplotype network indicates closer affinities to populations from western India and further suggests, with support from subfossil records, that the Mesopotamian Plain was colonized by humans some centuries ago. However, given the very limited sampling across the Mesopotamian Plain, further studies are needed in order to obtain a more robust insight into the phylogeographical history of this species across the region.

Background:
Identification of the larval stages of Echinostoma spp. in freshwater snails is an essential guide to continue monitoring the possibility of their transmission and the potential of echinostomiasis in areas where trematodes are the primary agent of parasitic diseases. The aim of this study was investigate Echinostoma using morphological and molecular techniques.
Methods:
The study was conducted in Gilan and Mazandaran Provinces, northern Iran, from April 2019 to October 2021. Overall, 5300 freshwater snails were randomly collected and were identified using external shell morphology. Meanwhile, snails infected with trematodes were studied via shedding and dissecting methods. Larvae stages of Echinostoma were identified and the genomic DNA of the samples was extracted. The PCR amplification of the ITSI gene was carried out for 17 isolates and products were sequenced. Seven sequences were deposited in GenBank.
Results:
Totally, 3.5% of snails containing three species (Stagnicola sp., Radix sp. and Planorbis sp.) were infected with two types of cercaria, E. revolutum with 37 and Echinostoma sp. with 45 spines in the collar. Moreover, 35% of the snails were infected with Echinostoma spp. metacercaria. Phylogenetic analysis illustrated that isolates were included in two ITSI haplogroups.
Conclusion:
Results showed the potential hazard of a zoonotic parasite as Echinostoma in northern Iran. The potential of disease environmental relationship investigation and resource control optimization is necessary for effective disease prevention and health management.
... However, they also serve as intermediate hosts for a wide range of trematode larvae of public health and veterinary importance with snail-borne parasitic diseases affecting people worldwide. Freshwater snails serve a direct role in distribution of parasitic trematodes larvae with the distribution of snails and parasitic diseases relatively correlated (Salahi- Moghaddam et al., 2011;Glöer and Pešić, 2012;Dodangeh et al., 2019). Thus, elimination or management of snail populations can be beneficial in the control and interruption of these diseases (Lu et al., 2018). ...
... In Iran, 73 species (34 genera representing 14 families) of freshwater snails have been identified, of which 9 species (from 6 families) have been reported to be infected with trematode larvae (Glöer and Pešić, 2012;Dodangeh et al., 2019). However, there are limited surveys documenting the prevalence and diversity of larval digenean trematode infection in lymnaeid snails in Iran. ...
Introduction: Lymnaea gedrosiana snails are hosts to a variety of trematode cercaria of public and veterinary health importance. In Guilan Province, Iran, a region with a high level of fish and bird farming and wetlands important for migratory birds, little is known about the trematode cercaria from L. gedrosiana.
Methods: From April 2020 to October 2021, six freshwater sites in Guilan Province
were sampled for Lymnaeidae snails three times per season (spring, summer, autumn and winter). Snails were exposed to light and heat to induce cercaria shedding and shredded cercaria were identified morphologically and molecularly.
Results: In total, 5,712 Lymnaeidae snails were collected of which 3,288 (57.6%) were identified to be L. gedrosiana with 54.3% containing trematode cercaria. Snail and cercaria recovery were highest in the spring and summer. Trematode cercaria identified included Telorchis assula, Hypoderaeum conoideum, Apharyngostrigea pipientis, Sanguinicola cf. inermis, Opisthioglyphe ranae, Diplostomum pseudospathaceum, and Australapatemon burti.
Discussion: The four trematodes D. pseudospathaceum, S. inermis, A. burti, and
A. pipientis have not been previously reported in Iran; all four of these can infect
migratory birds. The most common cercaria found, H. conoideum (18.3% of the
snails) is of zoonotic importance. The third most common cercaria found, S. inermis
(10.0% of the snails) is detrimental to fish production. Given the importance of the
wetlands in the region for wildlife and migratory birds as well as the number of fish
and bird farms in the area, efforts to control L. gedrosiana snails are needed to protect wildlife and human health. In addition, monitoring programs should be implemented to identify and prevent introductions of new trematode species.
... * Starobogatov (1970) included to the genus Caspiohydrobia the species Paludina elata Küster, 1852 described from Iraq (Küster, 1852). Its taxonomic identity is unclear; possibly, this species is a synonym of Ecrobia grimmi, which is also known from Iraq (Haase et al., 2010) and Iran (Glöer, Pešič, 2012). ...
The paper reviews all available information on the species content, distribution and ecology of brackishwater hydrobiid snails belonging to the genus Caspiohydrobia Starobogatov, 1970. The annotated list of nominal species with remarks on their taxonomy, nomenclature and distribution is provided as well as photographic images of some type specimens and/or topotypes. In total, the genus includes 31 nominal species distributed almost exclusively within the former Paratethys basin. The lectotype for the species C. cylindrica Logvinenko et Starobogatov, 1969 is designated. A short overview of the known habitat preferences of various Caspiohydrobia species is provided. We consider Caspiohydrobia a genus of Ponto-Caspian origin, whose range extends southwards to Iraq, Iran and Tajikistan and northwards to West Siberia. The actual species content of the genus as well as its generic independence require a further integrative revision, since most of the nominal species of Caspiohydrobia are still known from dried shells only and may actually be synonyms of a few (or even a single) species.

Snails are invertebrate organisms belonging to the Gastropoda class inhabit freshwater and other aquatic environments worldwide, some of them act as intermediate hosts for trematode and schistosome parasites. This study aimed to survey and compare the seasonal abundance of freshwater molluscs species in agricultural irrigation and drainage canals in Kafrelsheikh, Egypt. Also, the distribution of the intermediate host snails and their predators in this area was studied. The molluscs samples were collected from irrigation and agricultural drainage canals of three sites in Kafrelsheikh district from June 2019 to May 2020. Seventeen aquatic molluscs species belonging to 8 families and 2 classes were recorded in the Kafrelsheikh district. The species richness shows 16 and 14 molluscs species in agricultural irrigation and drainage canals, respectively. All species belonging to class Gastropoda except for Corbicula fluminalis and Mutela rostrata which belonging to class Bivalvia. The most abundant freshwater snail species in irrigation canals were Melanoides tuber-culate, Physa acuta, Helisoma duryi, and Bellamya unicoior, and in agricultural drainage canals were P. acuta, B. unicoior, L. carinatus, and Valvata nilotica. On contrary, Planorbis planorbis was non-detected in irrigation canals, while Theodoxus niloticus, Thi-ara scabra, and the bivalve, M. rostrata were non-detected in agricultural drainage canals. Thiara scabra was firstly recorded in Kafrelsheikh province. It could be concluded that the freshwater snail species and their population density were more diverse and numerous in irrigation canals compared to agricultural drainage ones and significantly depended on the time of the year.
... Bellamya bengalensis is widespread in southern Asia (Ramakrishna and Dey, 2007). Glöer and Pešić (2012) mentioned Melanopsis costata, distributed in Asia Minor, Syria, Palestine, Iraq, and Iran. ...
The current study was conducted in one of the most important water sources in Iraq, the Euphrates river to evaluate the diversity and density of Gastropoda and Bivalvia by using appropriate biodiversity indices. The samples were taken monthly from the river sediments, during the period from 1 July 2018 to 1 June 2019 from 3 stations, the distance between the first and second stations is 5 km and the second and third station is 7 km. The results showed the presence of 9 species, 7 of them belong to the Gastropoda and 2 belong to the Bivalvia. The total number of Mollusca was 2675 ind/m2. The species Melanoides tuberculata (Muller 1774) showed more relative abundance in the Euphrates River during the study period. The highest value for richness was recorded in March at station 3, while the Shannon Wiener diversity index, the results showed that the highest values were in April and May for all sites, and the highest value for eveness was recorded in January at Station 3, while the highest value for dominance was during October at station 3. Moreover, the current study included the monthly measurement of five environmental factors: water temperature, pH, salinity, dissolved oxygen, and organic matter.
