“…Water temperature interacts with other abiotic stressors as a driving force for impact. Its effect on ecological processes is due to the complex combined nature of the interaction of stressors [53]. Thermal pollution is a stress factor for aquatic ecosystems and is also capable of exacerbating the effects of anthropogenic pollution.…”

“…The reaction of an aquatic ecosystem to thermal pollution is assessed by the change in the state of its biotic part [54]. As a result of thermal pollution of water bodies, the production of organic matter in them begins to prevail over destruction, aerobic processes are replaced by anaerobic ones, the sanitary condition of water bodies deteriorates, and significant changes occur in biota [53]. A drop or increase in water temperature in the receiving water body of about 10 degrees or more is likely a value that leads to intense changes in the biotic part of the ecosystem [43,48].…”

The inheritance of historic human-induced disruption and the fierceness of its impact change aquatic ecosystems. This work reviews some of the main stressors on freshwater ecosystems, focusing on their effects, threats, risks, protection, conservation, and management elements. An overview is provided on the water protection linked to freshwater stressors: solar ultraviolet radiation, thermal pollution, nanoparticles, radioactive pollution, salinization, nutrients, sedimentation, drought, extreme floods, fragmentation, pesticides, war and terrorism, algal blooms, invasive aquatic plants, riparian vegetation, and invasive aquatic fish. Altogether, these stressors build an exceptionally composite background of stressors that are continuously changing freshwater ecosystems and diminishing or even destroying their capability to create and maintain ongoing natural healthy products and essential services to humans. Environmental and human civilization sustainability cannot exist without the proper management of freshwater ecosystems all over the planet; this specific management is impossible if the widespread studied stressors are not deeply understood structurally and functionally. Without considering each of these stressors and their synergisms, the Earth’s freshwater is doomed in terms of both quantitative and qualitative aspects.

“…High- temperature stress triggers formation of reactive oxygen species (ROS) in Volvox , which leads to sex-bearing forms (Nedelcu et al 2004 ). However, water has a high specific heat capacity, and in oceans, mean daily temperature variations are typically very narrow (<0.3 °C) (Morgan 2016 ). Nevertheless, despite the stress-buffering capacities of water, no marine photosynthetic organism is known that developed motility using neuromuscular systems.…”

The evolutionary advantage of different sexual systems in multicellular eukaryotes is still not well understood, because the differentiation into male and female individuals halves offspring production compared with asexuality. Here we propose that various physiological adaptations to oxidative stress could have forged sessility versus motility, and consequently the evolution of sexual systems in multicellular animals, plants, and fungi. Photosynthesis causes substantial amounts of oxidative stress in photoautotrophic plants and, likewise, oxidative chemistry of polymer breakdown, cellulose and lignin, for saprotrophic fungi. In both cases, its extent precludes motility, an additional source of oxidative stress. Sessile life form and the lack of neuronal systems, however, limit options for mate recognition and adult sexual selection, resulting in inefficient mate-searching systems. Hence, sessility requires that all individuals can produce offspring, which is achieved by hermaphroditism in plants and/or by multiple mating types in fungi. In animals, motility requires neuronal systems, and muscle activity, both of which are highly sensitive to oxidative damage. As a consequence, motility has evolved in animals as heterotrophic organisms that (1) are not photosynthetically active, and (2) are not primary decomposers. Adaptations to motility provide prerequisites for an active mating behavior and efficient mate-searching systems. These benefits compensate for the "cost of males", and may explain the early evolution of sex chromosomes in metazoans. We conclude that different sexual systems evolved under the indirect physiological constraints of lifestyles.
