“…Low temperatures together with the low conversion efficiency of solar energy by phytoplankton have been observed to be responsible for low productivity elsewhere (Talling, 1965;Khan, 1986). One of the prominent characteristics of phytoplankton and periphyton assemblages of the HALs is the dominance of Bacillariophyceae (Shah et al, 2014;Bashir et al, 2020) in lakes and wetlands. This may be attributed to their ability to get adapted to lower temperatures than other algae (Lürling et al, 2013).…”

“…The restricted research that exists is limited in diffuse and at times in unpublished sources. Although, several studies have been conducted to understand biological diversity and hydrochemical profile of the valley lakes in Kashmir Himalaya (Romshoo and Muslim, 2011;Parvez and Bhat, 2014;Nissa and Bhat, 2016;Rashid et al, 2017a;Khanday et al, 2018;Bashir et al, 2020;Dar et al, 2020a, b;Dar et al, 2021b), very few studies have focused on hydrobiological assessments of the HALs in Kashmir Himalaya (Zutshi, 1980;Zutshi and Vass, 1982;Zutshi, 1991;Shah et al, 2014). Thus, to fulfill this research gap the five HALs in the Kashmir Himalaya were selected to provide a comprehensive information on the LULC, bathymetry, hydro-chemical profile including the plankton diversity.…”

High altitude lakes (HALs) of Kashmir Himalaya are the important ecosystems in the mountain ecology of the broader Hindukush Himalayan region. This article provides a comprehensive information about the plankton (phytoplankton and periphyton) assemblages, water quality (WQ), bathymetry, morphometry, and land use land cover (LULC) of some select high altitude mountain lakes of Kashmir Himalaya. LULC analysis revealed that the catchment of the lakes spread over an area of about 16179 ha, is covered by different land cover types dominated by pastures (50.8%), followed by barren rocky (32.6%), snow and glaciers (11.9%), lakes (2.5%), forest (2%), and streams (0.2%). Bathymetric and morphometric analysis revealed that the Gangbal Lake is the deepest (84 m) and largest (162.4 ha) among the investigated lakes. The water quality index revealed that all the HALs have the excellent water quality category. Statistical analysis (Wilk’s λ) depicted that nitrate-nitrogen (NO3−-N), nitrite nitrogen (NO2−-N), ammoniacal nitrogen (NH3-N), total phosphorus (TP), and magnesium hardness (Mg-H) are responsible for major variability between all HALs sites. The cations followed the order of Ca2+ > Mg2+ > Na+ > K+ while as anions followed the order as HCO3− > Cl− > SO42−. Algal composition (phytoplankton and periphyton) assessment revealed the presence of 61 taxa belonging to Bacillariophyceae (45), Chlorophyceae (14), Cyanophyceae (1), and Xanthophyceae (1). The higher dominance of Bacillariophyceae indicates oligotrophic nature of the lakes. Canonical correspondence analysis (CCA) highlighted the role of various water quality parameters like pH, EC, and TDS on the composition of phytoplankton and periphyton species among the lakes. The present study therefore generated a baseline database for some of the HALs of Kashmir Himalaya that can act as a precursor for more research on future changes in the lake ecosystems of the region.

“…Dal Lake is an urban valley lake in Srinagar, India, known for its beauty and cultivation of the Indian lotus (Shah et al 2014). The present study deciphered the prokaryotic community structure associated with the lake samples and the root, rhizome, leaf, ower, and fruits of lotus cultivated in the Dal Lake.…”

“…Dal Lake is a postglacial, urban water body regarded as one of the most beautiful lakes in the world located between 34°6'N and 34°10'N latitude and 74°50'E and 74°54'E longitude in the middle of Kashmir Valley (Shah et al 2014). This shallow, open-drainage lake is fed by Dachigam-Telbal Nallah (with the perennial ow), Dara Nallah along with several minor streams.…”

Prokaryotic communities adapted to microhabitats on the Indian lotus (Nelumbo nucifera) growing in the high-altitude urban Dal Lake

et al. 2022

Indian lotus (Nelumbo nucifera) is one of the dominant aquatic plants cultivated in Dal Lake, situated at 1586 m above MSL in the northeast of Srinagar, Kashmir. Despite their economic and ecological role, the microbial communities associated with the lotus plant are still unexplored. In this study, we investigated prokaryotic communities harboured by different lotus microhabitats (roots, rhizome, leaves, owers and fruits), lake water, and sediments using 16S rRNA gene amplicon sequencing. Overall, prokaryotic diversity decreased signi cantly on the lotus in comparison to the lake water and sediments. Among the microhabitats of lotus, roots and leaves harboured more diverse communities in comparison to rhizomes, fruits and owers. A total of 98 genera were shared by lotus and the Dal Lake sediments and water.However, signi cant differences were found in their relative abundance, like Pseudomonas was the most dominant genus on most lotus microhabitats. On the other hand, Flavobacterium was highly abundant in the lake water, while a higher abundance of Acinetobacter was recorded in sediments. Additionally, signi cant differences were recorded in the proportion of several genera including Pseudomonas, Clostridium, Sphingomonas, Erwinia, Lactococcus, Rhizobium, Weissella, and Raoultella among the lotus microhabitats. Predicted functions of prokaryotic communities revealed a higher abundance of genes associated with nutrient uptake in the microhabitats of the lotus. This study offered rst-hand information on the prokaryotic communities harboured by lotus plants and water and sediments of the Dal Lake and demonstrated the adaptation of diverse communities to microhabitats of lotus.

“…It has an area of about 1670 ha, a total catchment of about 317 sq. km, divided into five sub-catchments (Shah, 2012). Based on early causeways and projecting marshy lands, the lake is divided into three parts: Lokut-Dal (Little Dal) , Bod-Dal (Big Dal) and Soderkhan.…”

PurposeA wetland is a place of tourist attraction, and tourism values play a key role in economic development. Among various services provided by a wetland, recreational services are increasingly valuable in the tourism sector. This paper aims to unfold the potential recreational values of the Dal Lake in Jammu and Kashmir, India.Design/methodology/approachThe study uses individual travel cost methods (TCMs) and assesses its impact on regional development in terms of income and employment generation. A sample of 200 tourists is selected through an on-site survey on Dal Lake, and the demand for recreational visits and its value is estimated by employing the truncated Poisson regression model (TPRM) and un-truncated Poisson regression model (UTPRM). The consumers' surplus is estimated and tourists' benefit to visiting the wetland is explored.FindingsOn average, estimated consumers' surplus per visitor is Rs 6,250 (US$96.15) and Rs 25,000 (US$384.61) from respective models. The annual total recreational value of the lake is accounted for Rs 1713m (US$ 26m). This high consumer surplus (CS) and recreational values of the lake indicate large demand for its recreational facilities.Originality/valueThe study is based on primary data and thus, is original. The paper has implications for the policymakers to formulate sustainable management plans for the proper use of Dal Lake and tourism development.
