“…The ecosystem of this wetland is affected by pollution from nearby cities, wastewater effluents, tourism and fishing activities (Naderi and Saatsaz, 2020;Rasta et al, 2020). Our team reported 362 ± 327.6 MPs/kg sediment from 40 superficial sediment samples across the 193 km 2 wetland (Birami et al, 2022). Microplastic pollution was also documented in the GI tract, muscle, and gonads of some fish species in the wetland by Rasta et al, (2021).…”

“…MPs > 10 4 μm did not translocate across the GI tract epithelium in several studies (Kim et al 2020;Pyl et al, 2022). Although the ingestion of MPs by marine organisms is well documented (Daniel et al, 2020a;Nematollahi et al, 2021;Rasta et al, 2021;Saemi-Komsari et al, 2022), other exposure pathways such as inhalation and contact have been less studied (Huang et al, 2020;.…”

“…Freshwater ecosystems are among the most threatened ecosystems on the earth (Stewart et al., 2022 ). Aquatic organisms in these freshwater environments face numerous threats, for example, habitat degradation, hydrology alterations, pollution, overexploitation, and invasive species (Davies & Stewart, 2013 ; Dudgeon et al., 2006 ; Reid et al., 2019 ; Saemi‐Komsari et al., 2023 ; Stewart et al., 2022 ). These freshwater ecosystems are considered the most vulnerable freshwater systems to climate changes and during the past several decades have faced with many treats including reduced rainfall, a decrease in the river discharge, and a warmer temperature.…”

Freshwater fishes are facing considerable threats in the Arabian Peninsula which is considered as a highly stressed region in the Middle East. It is predicted that northern Oman is likely to face decreasing rainfall and increasing temperature in coming decades. In this study, we focused on an endemic cyprinid fish Cyprinion muscatense, as a model to investigate impacts of climate change on the mountain fishes inhibiting in this arid region. This species is expected to be strongly affected by climate change because of its limited distribution range in a montane area surrounded by lowlands and sea, limiting the species in shift to other areas. We used an ensemble approach by considering two regressions‐based species distribution modeling (SDM) algorithms: generalized linear models (GLM), and generalized additive models (GAM) to model the species habitat suitability and predict the impacts of climate change on the species habitat suitability. Based on the distribution models, the montane area located in northeastern Oman was identified as the most suitable habitat for this species. Our results indicate that, even under the minimum greenhouse gas emissions scenario (RCP 2.6), climate change will produce a high reduction in its potential future habitats. According to the results of percent contribution, elevation and annual minimum temperature were the most important variables in predicting the species suitable habitats. Results also showed that only a small percentage of suitable habitats for the species within boundaries of protected areas. Therefore, the impact of climate change on the species appears particularly alarming. Although our study was restricted to a single cyprinid freshwater species, decreases in potential habitats are likely predicted for other cyprinid fish species restricted to the mountains of this region, suggesting severe consideration is needed for aquatic systems in future conservation planning, especially for endemic freshwater fishes.

Climate change is expected to affect freshwater water bodies worldwide, especially those located in semiarid and arid regions, including the Arabian Peninsula. Species distribution modeling has been widely used to predict the effects of climate changes on aquatic species. Occurrence records of the cichlid fish Nile tilapia, Oreochromis niloticus, were geographically mapped, followed by the implementation of species distribution models to delineate its range within the sensitive inland water system of the southeastern Arabian Peninsula. The analysis encompassed the examination of species presence data in the context of environmental variables, leading to the development of an ensemble model for habitat suitability, combining four distinct species distribution models. The findings indicated that the mean diurnal range and precipitation seasonality emerged as the most influential factors in predicting the suitability of habitats for O. niloticus. The response curve analysis indicated that the presence probability of O. niloticus decreased with increasing mean diurnal range and decreasing precipitation seasonality. The suitable distribution ranges for O. niloticus in the studied area were mainly distributed in the northeast of this region, where native/endemic fish diversity is high. The ensemble model results specified a significant impact of climate change on O. niloticus distribution, so highly suitable areas for this species will be reduced, while areas with low to moderate suitability increase slightly or remain unchanged. While O. niloticus is anticipated to display resilience and prosper under the influence of climate change, it remains paradoxical that its habitats are at risk of being compromised by climate-induced alterations. Consequently, even this resilient species stands susceptible to the repercussions of climate change. Due to the worldwide severe impacts of Nile tilapia, regular monitoring of freshwater ecosystems and fish fauna—especially in the northeast of the Arabian Peninsula, which has currently been invaded by this alien species—and protecting the region from key anthropogenic stressors are recommended to successfully conserve the freshwater fishes, which include about 22 recognized fish species in 16 genera, 10 families, 7 orders, and a class including 20 natives (7 endemic) species, out of which 13 species co-occur in sympatricity with O. niloticus.
