Summary: This study evaluated the ecotoxicity of silica nanoparticles (SiNP) in the presence/absence of copper on mosquitofish. The results showed that the presence of copper reduced the number of bacteria on the fish's skin, decreased liver damage, activated the antioxidant system, and caused lipid oxidative damage when SiNP and copper were mixed.

Summary: This study aimed to investigate correlations between environmental events, geochemistry variations, and ecological risks along the coastal Tajan River, particularly during wet seasons. Analysis of toxic metal concentrations revealed a moderate ecological risk in the coastal and urban areas, with recommendations for controlling sources of toxic metals and dredging. Significant correlations were found between toxic metal concentrations and Caspian Sea level fluctuations.

Summary: This study found sex-specific differences in heart rates of Gambusia holbrooki embryos during development, with females showing higher heart rates and resting time compared to males, and this difference persisted into adulthood. The results suggest that cardiac sex-dimorphism manifests early in development and continues through adulthood in this species.

Summary: In this study, the general form of the spectrum was used to mathematically describe the spectrum of the Caspian Sea waves. Five spectral models were compared and it was found that the Krylov model performed the best for narrow spectra, the Donelan model performed the best for broad spectra, and the PM model performed the best for medium-width spectra.

Summary: The sea breeze system is the dominant atmospheric forcing in the southern Caspian Sea, and it has a significant impact on the water column. Observations and modeling suggest that the sea breeze system results in diurnal baroclinic current signals and surface height changes. These findings provide a better understanding of the response of the water column to the sea breeze system.

Summary: This study described the life-history characteristics of the Caucasian dwarf goby collected in the highly degraded Gomishan wetland of Iran, including short lifespan, female dominance, low fecundity, large oocytes, and dependence on the wetland for spawning. Given the adverse environmental changes in wetlands, this species is likely to face a high risk of extinction.

Summary: This research investigates the reasons for changing agricultural land use to tourism in a developing country (Iran) with different political, economic, and social contexts. The results show that both macro and micro factors affect this process, including the weakness of the agricultural sector, the inadequate land use laws, the lack of inter-organizational coordination in law enforcement, the weakness of the property registration system, the lack of government support for the agricultural sector, the rapid increase in land prices, and the changing attitudes of farmers towards agriculture and welfare.

Summary: This study investigates the expression of germ plasm markers during embryonic development in Gambusia holbrooki, and suggests that the reproductive developmental adaptations in this species may reflect a transition from lecithotrophy to matrotrophy.

Summary: This study investigates the haplotypic and genotypic diversity of Gambusia species in India using molecular tools. It reveals a greater distribution of Gambusia holbrooki and a lesser occurrence of Gambusia affinis in India. Population genetic analysis shows low genetic variability and significant population genetic structuring among G. holbrooki populations.

Summary: This study investigated the spatio-temporal expression of teleostean germ plasm markers in Gambusia holbrooki, and found that both maternal inheritance mode and strictly zygotic activation mode exist in this species. The PGC clustering, migration, and colonization patterns of G. holbrooki resemble those of zebrafish, medaka, and mice, indicating evolutionary similarities. Furthermore, the expression domains of PGC markers in G. holbrooki show both teleost-specific and murine model-specific characteristics.

Summary: The study investigated the occurrence of microplastics (MPs) in inshore and offshore surface waters of the southern Caspian Sea. The data showed that MPs were widely distributed in the thirteen studied stations, with non-normally distribution observed among the stations. The average concentration of microplastics in the selected stations was 0.246 +/- 0.020 MP/m(3).

Summary: This study aimed to evaluate an alternative approach to characterize hydrological processes in a watershed and test its potential to replace traditional calibration. Results showed that the regional calibration method (RC) can effectively predict hydrological processes in a specific watershed, but further development is needed to enhance accuracy.

Summary: The study describes the embryonic developmental stages of Gambusia holbrooki from zygote to parturition, dividing them into 40 stages grouped into seven periods. Quantitative and qualitative data were used to describe each stage, highlighting the influence of narrow perivitelline space, placentation, internal gestation, and sex differentiation on developmental novelties.

Summary: The presence of microplastics (MPs) in beach sediments of the southern Caspian Sea has been confirmed, but there are still uncertainties regarding the abundance and distribution of MPs in the rivers that flow into the Caspian Sea. This study surveyed the bank sediments of 26 sites in thirteen rivers during two seasons, and found no significant difference in MPs concentrations between the seasons. MPs were detected in all samples, with an average concentration of 214.08 +/- 14.35 MPs/kg. The most common characteristics of MPs were size L < 300 μm, shape fragment/film, color white/transparent, and polymer type polystyrene (PS). Positive gradients of MP concentrations from upstream to downstream were observed in all rivers, with the highest concentrations found in the downstream parts of Chalus, Haraz, and Safarud rivers. Recreational-tourism and fishing activities were significantly associated with MPs concentrations in the rivers.

Summary: The study found that leaping mullet had the highest frequency of microplastics (MPs) in their gut in the southern Caspian Sea biome, while Caspian kutum had the lowest. MPs were mainly in fiber shape, and the dominant polymers were black MPs, polystyrene, polypropylene, and polyethylene terephthalate. Different fish species showed significant differences in condition index, suggesting that MPs may have adverse health impacts on leaping mullet and common carp, but not on Caspian kutum.

Summary: Cobitis faridpaki, a small endemic loach, was studied in northern Iran to investigate its reproductive parameters including sex ratio, spawning season, fecundity, and oocyte diameters. The study found a dominance of females during the pre-spawning and spawning periods and determined the spawning period to be from late March to early May. The absolute and relative fecundity of females were found to be positively correlated with total length and weight. The study also observed a multi-modal distribution of oocyte diameters, indicating that the species is a multispawner. This research provides important information for future conservation programs.

Summary: This study provides comparative population dynamics information for Palaemon adspersus and P. elegans shrimps on the southeastern coast of the Caspian Sea. The results show that both shrimps have the highest abundance in autumn. The average total length is different between the two species, with P. adspersus being larger than P. elegans. Additionally, there are differences in growth type and recruitment pattern between the two shrimp species.

Summary: The study found that diatom species diversity is highest in winter and lowest in spring. Temperature and salinity are the major factors influencing diatom diversity and abundance along the Caspian Sea shore. Thalassiosira fasciculata, T. caspica, and Melosira caspica are recommended as biological indicators in this area.
