“…The pattern of genetic differentiation in the Yangtze River finless porpoise may reflect its habitat. Freshwater and seawater environments differ in many ways, with the higher salinity of seawater promoting oxidative stress (Bal et al., 2021). Such adaptations may be mirrored by the harbour porpoise ( Phocoena phocoena ), a species sequenced in 2018 (Autenrieth et al., 2018).…”

Cetacea, whales, dolphins and porpoises form an order of mammals adapted to aquatic life. Their transition to an aquatic habitat resulted in exceptional protection against cellular insults, including oxidative and osmotic stress. Here, we considered the structure and molecular evolution of the superoxide dismutase (SOD) gene family, which encodes essential enzymes in the mammalian antioxidant system, in the superorder Cetartiodactyla. To this end, we juxtaposed cetaceans and their closest extant relatives (order Artiodactyla). We identified 94 genes in 23 species, of which 70 are bona fide intact genes. Although the SOD gene family is conserved in Cetartiodactyla, lineage‐specific gene duplications and deletions were observed. Phylogenetic analyses show that the SOD2 subfamily diverged from a clade containing SOD1 and SOD3, suggesting that cytoplasmic, extracellular and mitochondrial SODs have started down independent evolutionary paths. Specific‐amino acid changes (e.g. K130N in SOD2) that may enhance ROS elimination were identified in cetaceans. In silico analysis suggests that the core transcription factor repertoire of cetartiodactyl SOD genes may include Sp1, NF‐κB, Nrf2 and AHR. Putative transcription factors binding sites responding to hypoxia were (e.g. Suppressor of Hairless; Su(H)) found in the cetacean SOD1 gene. We found significant evidence for positive selection in cetaceans using codon models. Cetaceans with different diving abilities also show divergent evolution of SOD1 and SOD2. Our genome‐wide analysis of SOD genes helps clarify their relationship and evolutionary trajectory and identify putative functional changes in cetaceans.

“…The increase in world population is associated with increasing demand for water, and the world's water resources are declining due to phenomena such as global warming, drought and various other reasons [8]. As a result it leads to global water scarcity, environmental pollution and increasing salinity of land and water resources are prominent features to aff ect both plants and animals in the 21 st century [9][10][11][12]. On the other hand, about 10 million hectares of the world's agricultural lands are removed from the production cycle due to irrigation salinity.…”

“…It therefore reduces plant growth, thus limiting production [13]. Salinity aff ects the physiology of organisms in general and growth rate and absorption capacity of the metal in particular in plants and animals [10][11][12]. Findings of Leblebtect, et al [14] on the eff ect of salinity on growth and accumulation capacity of heavy metals in Spirodela polyrrhiza (Lamnase) showed that at high salinity levels (100 and 200 mM) decreased the relative growth rate and came down the accumulation of cadmium and nickel by plant.…”

Heavy metals are elements that mainly have a 5-22 gr.cm-3 specific gravity. Some of these metals are essential micronutrients for plant growth (Such as Zinc (Zn), Copper (Cu), Manganese (Mn), Nickel (Ni) and Cobalt (Co)). Some other heavy metals, have a high toxicity properties such as Lead (Pb), Cadmium (Cd) and Mercury (Hg). In order to investigate the potential of watercress (Nasturtium officinale) in the uptake of elements from nutrient solutions with different salinities, a factorial experiment was conducted in a completely randomized design with three replications in the greenhouse. In this experiment, different levels of arsenic were zero, 5, 10, 20, 40, 40, 80 and 160 mg.L-1, which were obtained from sodium arsenate source and added to Epstein’s nutrient solution to obtain the mentioned concentrations. The salt concentration of the nutrient solution was 0, 10, 20, 40 and 80 mM which was prepared from sodium chloride source and added to Epstein solution. After making nutrient solutions with different salinity and concentrations, watercress was cultivated. The ANOVA results showed that the interaction of salinity and arsenic levels on the calcium, magnesium, iron, manganese, zinc and copper concentrations in watercress was significant at the level of one percent probability. The highest concentrations of these elements were obtained in the levels without salinity and arsenic and the lowest values were obtained in the 80 mM salinity levels and 160 mg.l-1 arsenic.

“…For the first time, ultra-modern human species lifted the weight of nurturing nature by doing nothing but only keeping themselves off the street and locked inside home to get rid of COVID-19 infection. Our previous studies indicate that the health of ecosystems and associated events in most of the urban and sub-urban areas were unexpectedly damaged due to high anthropogenic, vehicular and industrial activities or climate change issues (Bal et al, 2021 ; Paital et al, 2015 , 2016 ; Paital, 2016a , 2016b ; Chainy et al, 2016 ). In the former case, it is pertinent that environmental audits were not stringent in India and in many other countries (Supplementary Fig.…”

Positive effects of COVID-19-induced lockdowns on environment are well documented although pre-planned experiments for such analyses and appearance of fish species are lacking. We hypothesize that spotting the fish Aplocheilus panchax along the industrial belt of Mahanadi River near Cuttack in a never seen manner could be due to the regenerated environment. Heavy metals, water and air qualities along with spotting A. panchax in up, mid and downstream of Mahanadi River near Jagatpur industrial basins were analysed during pre-(end of March 2020) and after 60 days of lockdowns (last week of May 2020). An overall 45, 61, 79, 100, 97 and 90% reduction of Fe, Cu, Ni, Cd, Pb and Zn was recorded in the studied area after lockdowns, respectively. Similarly, dissolved oxygen and pH were elevated by 26 and 7%, respectively. Water temperature, conductivity and total dissolved solute levels were reduced by 7, 46 and 15%, respectively, which were again elevated during post-lockdowns during 2021 as observed from the Landsat-8 OLI satellite data. Air NO 2 , SO 2 , NH 3 , PM 2.5 , PM 10 and CO levels were alleviated by 58.75, 80.33, 72.22, 76.28, 77.33 and 80.15%, respectively. Finally, for the first time, about 12 A. panchax fish per 100 m shore line in the area were spotted. The observed lockdown-induced environmental healing at the studied area could contribute to the appearance of A. panchax in the study site and therefore a stringent environmental audit is suggested during post-COVID-19 periods to make the regenerated environmental status long lasting in such habitats.
