Interrelationships, origin and phylogenetic affinities of brown trout Salmo trutta populations from the southern Caspian Sea basin, Orumieh and Namak Lake basins in Iran were analysed from complete mtDNA control region sequences, 12 microsatellite loci and morphological characters. Among 129 specimens from six populations, seven haplotypes were observed. Based on mtDNA haplotype data, the Orumi...

The physical structure of vegetation influences diversity, interactions, movement, and thermoregulation of animals. Vegetation structure might be a good indicator of habitat requirements of generalist predators, such as dragonflies and damselflies (order Odonata), and thereby affect species diversity. Odonates use aquatic and terrestrial habitats during larval and adult life stages, respectivel...

During a study carried out in spring-summer 2010, the invasive Ponto-Caspian polychaete Hypania invalida (Grube, 1960) was recorded for the first time in the southern part of the River Odra estuary (southern Baltic). This is the first record of this species in Poland or in any a Baltic estuary. The appearance of H. invalida in the Odra estuary coincided with flood water descent in the Odra, sug...

We quantified the distribution, abundance and assemblage structure of macrofauna at 22 stations in Gorgan bay, seasonally in 2012-2013. Also, depth, temperature, salinity, DO, TOM and sediment particle size were measured in each station. The highest concentration of TOM was measured near the western littoral zone (10.22) while the mouth part and north-eastern area was characterized by the lowes...

The spatial distribution and patterns of habitat use of littoral fish species in Lake Constance were studied using electric fishing and trammel net sampling to assess fish abundance and biomass in three depth strata at six different sampling sites within the littoral zone. Distribution differences among depth strata were found to be often more pronounced than among different sampling sites. Juv...

there are two species of ghost shrimps namely, neocallichirus jousseaumei, n. calmani of which the latter is the first record for the persian gulf (littoral and subtidal zones). while, n. jousseaumei is first record for littoral zones along coastal waters of the persian gulf. the material of present study was collected from ouli village along the coast of bushehr province. here, notes on habita...

Bream (Abramis brama, Berg, 1949; Family: Cyprinidae) is commercially valuable fish in the Caspian Sea fishing industry. Iranian Fisheries Organization annually produces and release up to 19 million Bream fries size for recruiting of this species. Its fries are mostly released into the Anzali wetland with 4 ppt salinity. Meanwhile, they sometimes are released into Sefidrood River (0.5 ppt), Sef...

Legally certified sturgeon fisheries require population protection and conservation methods, including DNA tests to identify the source of valuable sturgeon roe. However, the available genetic data are insufficient to distinguish between different sturgeon populations, and are even unable to distinguish between some species. We performed high-throughput single-nucleotide polymorphism (SNP)-geno...

Littoral dipluran Parajapyx pauliani Pagés, 1959 was redescribed based on the specimens collected in Hainan Island, South China. The littoral habitat was confirmed for the species, as the first report of arenicolous dipluran in China. DNA barcoding fragment was sequenced for five Parajapyx species (18 individuals) from China, and this is the first report on DNA barcodes used for dipluran identi...

Zooplankton communities were investigated in a turbid shallow lake with an aim to analyze (i) relationships between ecological conditions and the communities and (ii) trophic state inferred from abiotic and biotic indicators. According to results emerged littoral vegetated zone increased diversity (30 taxa) in comparison to the pelagial (17 taxa). Rotifers dominated in terms of diversity and ab...
