Abstract (English):
Based on the assumptions of many researchers, global warming and anthropogenic factors such as pollution, transporting and trading, as well as invasionism, lessepsianism, endangerism effect negatively and will continue to effect aquatic populations and their existence in the ecosystem and related habitats. Thus, it may be stated that climate warming and anthropogenic factors will certainly cause extinction of some aquatic organisms as well as fish species in the end, by 2080 or 2100. Considering economic impacts of losing some species, the new areas of fishing should be decided to sustain current needs of human and food industry. In this paper, the effects of global warming, natural and anthropogenic factors affecting aquatic life were discussed by using the data from various reports.

global warming, climate change, bio diversity, anthropogenic factors
Introduction. Porter et al. [1] stated that in the last 50 years, it has been at accelerated rate for the loss of biodiversity due to human activities and some other factors such as habitat loss, overexploitation, invasive species, climate change, and pollution. Negatively human activities [2] and the effect of climate changes on marine ecosystems bear many problems to be solved [3]. It is mentioned that marine diversity has been affected by pollution particularly from ship breaking and recycle industry pollutants, overproduction and incorrect disposal of pharmaceuticals and overfishing [4, 5]. Fishing reduces the age, size, and geographic diversity of populations and the biodiversity of marine ecosystems [6]. Disturbing of prey-predator balance causes extinction of the indigenous and newly introduced species and results biological pollution. Altaf et al., [7] related to the presence of 27,977 fish species with 515 families and 62 orders in the World. Transferring some of them on purpose for biological fight from one source to another creates some negative interactions. What if there has not been opening Suez channel, then where would these lesseptian species would migrate? Who is the responsible in this case man? or global warming? The present report summarises sources, factors, mechanisms of climate change, investigates interactions of global warming with anthropogenic activities and possible remedial measures of all of these challenges on biodiversity of aquatic organisms Natural and anthropogenic factors affecting aquatic life. Aquatic ecosystems, particularly nutrient and carbon cycles may be effected by climate changes together with increasing deposition of woody debris from human activities, and alteration of environmental factors such as water pollution, and dam building. Pharmaceuticals are an important pollution source, mostly due to overproduction and incorrect disposal. Ship breaking and recycle industries [SBRIs] can also release various pollutants and substantially deteriorate habitats and marine biodiversity. Overfishing is significantly increasing due to the global food crisis, caused by an increasing world population. Organic matter (OM) pollution and global warming (GW) are key factors that exacerbate these challenges (e.g. algal blooms), to which acidification in marine waters should be added as well. It was reported that changes in environmental factors effected negatively freshwater lignicolous fungi in Asian/Australian region [8]. Introductions of non-native species have been accepted as major threats to ecosystem function and biodiversity. It is reported that geothermal areas may provide an ecological passage for aquatic organism to response global warming [9]. In marine habitats, fish movements will continue based on their temperature preferences. For example, eurybiontic species have the ability to tolerate a wider range of environmental conditions than typical Arctic inhabitants and will gain advantages in development [10]. Janssens et al. [11] mentioned that the major factors for aquatic biodiversity were global warming and pesticide pollution. They reported that larval pesticide stress and adult heat stress interacted across metamorphosis, and sensitivity to pesticides may be graded by intraspecific evolution along natural thermal gradients. A connection was described between genetic structure and climate change and habitat disruptions by using a modified landscape genetics approach in yellow perch (Perca flavescens) living large connected ecosystems and isolated relict populations with advising using this data for further climate change impacts [12]. Pilas and Planinsek [13] advised that the re-establishment of the water regime of lowland forests may reduce the impact of climate change in the future. To reduce negative impacts of anthropogenic alternations in the groundwater regime from the past and to attenuate slow down future very possible prolongation of droughts and water scarcity in the lowlands, various forest managerial and engineering practices should be applied. Verberk et al. [14] reported that one of the main causes of the decline of freshwater biodiversity was considered as biological invasions caused by climate change [15]. With the assumption of increases in global temperatures alter geographical distributions of native and invasive species, they used «killer shrimp» Dikerogammarus villosus as invider and native Gammarus pulex, and found that the invader was more vulnerable to high temperatures than G. pulex showing that global warming was less favorable to the invasive species. Kolicka et al. [16] reported native and alien Rotifera, Copepoda, Polychaeta, Acari and Insecta larvae in greenhouses of Poznan in Poland. Global warming has been demonstrated to contribute to the increase of hypoxic conditions driven by climatic factors, such as river discharge and air temperature proven by statistical modeling [17]. It is predicted that there will be a loss of suitable habitat in northern inland distribution and increase in coastal habitats of salt marsh morning glory (Ipomoea sagittata) in the Gulf of Mexico by the year of 2080 [18]. Conclusion. Global climate change has major effects on wetlands and ecosystems. Ashraf et al. [19] recommended that worldwide attentions should continue to conserve the threatened ecosystems and their related biodiversity as the risks still valid for habitat degradation by polluting both terrestrial and aquatic ecosystems, emitting air pollutants resulting in acid rains, ozone layer depletion, global warming, heavy metal contamination and eutrophication of water bodies. Although guidelines and legislative proposals have been prepared to reduce the effects of climate change, how endangered species will be effected? by such activities have still unknown. Therefore, further studies are required at different species and various regions in the World
