“…The total coliform concentration in water was determined by multiple-tube fermentation technique (Akeju and Awojobi, 2015; Aneja, 2007). The technique involved three steps including: Presumptive, Confirmatory and Completed tests following Akeju and Awojobi, (2015).…”

The spread of Covid-19 has reduced human intervention in aquatic ecosystems, which has shown a discernible improvement in air and water quality. Ganges River, being a historical, economic and cultural icon of India providing multiple ecosystem services as industrial, provisioning, regulatory and cultural services, constitutes an important habitat for Gangetic Dolphin (Platanista gangetica). The surfacing of dolphins in Ganga river is patchy and unpredictable. The present study unravels 25 different chemical, microbiological, biological and meta-genomics of most abundant bacteria at dolphin surfacing sites in Ganges water during October 2017 February 2018 and January 2021 to elicit the impact of Covid-19 lock down at the Garhmukteshwar (28.7601°N, 78.1437°E) stretch in Hapur district of Uttar Pradesh, India. The most abundant bacteria at dolphin surfacing site was Bacillus subtilis in February 2018 which was replaced by Aeromonas sp. in January 2021. The zooplankton community was dominated by rotifers during pre-Covid period however the dominance pattern recorded a shift towards larger herbivorous crustacean species during Covid −19 lock down. Overall bacterial count decreased whereas Chl a level increased during the lock down. The total zooplankton abundance did not show a significant difference, but relative proportion of larger herbivorous crustacean zooplankton increased in January 2021 samples. The present results convincingly establish effects of shutdown on chemical, metagenomics and biological components of the riparian ecosystem and the information of micro to mesoplanktonic community may be useful for characterizing dolphin surfacing sites, enhancing existing water quality monitoring efforts and also for human epidemiological studies associated with recreational use of Ganga water.

“…For microbiological analyses, previously mentioned methods were followed after little modification (Akeju and Awojobi, 2015). Lauryl Triptose broth was used as a medium in presumptive coliform test (Ali et al, 2011;Anwar et al, 2010).…”

The present study involves the chemical and bacteriological analysis of water from different sources i.e., bore, wells, bottle, and tap, from Peshawar, Mardan, Swat and Kohat districts of Khyber Pakhtunkhwa (KP) province, Pakistan. From each district, 50 water samples (10 samples from each source), regardless of urban and rural status, were collected from these sources and analysed for sulphates, nitrates, nitrites, chlorides, total soluble solids and coliforms (E. coli). Results indicated that majority of the water sources had unacceptable E. coli count i.e.> 34 CFU/100mL. E. coli positive samples were high in Mardan District, followed by Kohat, Swat and Peshawar district. Besides this, the some water sources were also chemically contaminated by different inorganic fertilizers (nitrates/nitrites of sodium, potassium) but under safe levels whereas agricultural and industrial wastes (chloride and sulphate compounds) were in unsafe range. Among all districts, the water quality was found comparatively more deteriorated in Kohat and Mardan districts than Peshawar and Swat districts. Such chemically and bacteriologically unfit water sources for drinking and can cause human health problems.

Context Tourism is becoming one of the largest and fastest growing industries in many countries. Increasing tourism exerts serious impacts on the habitats of wildlife in nature reserves. Aims To ascertain how tourism affects the habitat of the Chinese giant salamander (Andrias davidianus), especially water quality and population size. Method An experiment was conducted to investigate the influences of different tourism disturbance intensities on the habitat quality and population size of the Chinese giant salamander in the Hunan Zhangjiajie Chinese Giant Salamander National Nature Reserve. Habitat characteristics, water physicochemical properties and microbial abundance were analysed, and population size estimated. Key results The results showed that high levels of tourism disturbance (>100 000 visitors per year) had negative effects on habitat quality. These effects included increased noise and abundance of aquatic microbes, increased concentration of total nitrogen (TN) and total phosphorus (TP) and a reduction of dissolved oxygen (DO) in water. The abundance of Escherichia coli could be regarded as an indicator of tourism disturbance on Chinese giant salamander. Conclusions It is concluded that: (1) the habitats were much noisier with increasing numbers of tourists, which might directly reduce the population size; (2) tourism indirectly disturbs the salamander population by increasing TN and TP, and reducing DO in the water; and (3) tourism might take in pathogenic microbes to the water habitats, which could cause disease for the salamander population. Implications Although tourism development might reduce local poverty, such efforts must consider the deterioration of habitats for wildlife, especially for this endangered animal species. Moreover, the intensity of tourism disturbance needs be reduced (by controlling the number of tourists) to achieve the coordinated development of tourism and wild animal protection.
