Western Nepal is known for its rich freshwater resources that support diverse flora and fauna. Freshwater ecosystems of western Nepal provide multitudes of ecosystem goods, services (irrigation, hydroelectricity, drinking water) to humans, and provide breeding and feeding grounds for many wetland-dependent flora and fauna. But these wetlands are under tremendous pressure mainly due to anthropogenic activities. In this review, we provide a brief overview of the freshwater biodiversity, distributions of wetlands and their status in western Nepal. From this review, we found that western Nepal is rich in freshwater resources and supports diverse flora and fauna. The biologically significant Karnali River is the home of a globally endangered species, the South Asian river dolphin. We also discuss the conservation history of wetlands, identify the gaps, and further suggest priority hotspots for the formulation of future conservation strategies for these ecosystems.

Dancing Women: Choreographing Corporeal Histories of Hindi Cinema, an ambitious study of two of South Asia’s most popular cultural forms—cinema and dance—historicizes and theorizes the material and cultural production of film dance, a staple attraction of popular Hindi cinema. It explores how the dynamic figurations of the body wrought by cinematic dance forms from the 1930s to the 1990s produce unique constructions of gender, stardom, and spectacle. By charting discursive shifts through figurations of dancer-actresses, their publicly performed movements, private training, and the cinematic and extra-diegetic narratives woven around their dancing bodies, the book considers the “women’s question” via new mobilities corpo-realized by dancing women. Some of the central figures animating this corporeal history are Azurie, Sadhona Bose, Vyjayanthimala, Helen, Waheeda Rehman, Madhuri Dixit, and Saroj Khan, whose performance histories fold and intersect with those of other dancing women, including devadasis and tawaifs, Eurasian actresses, oriental dancers, vamps, choreographers, and backup dancers. Through a material history of the labor of producing on-screen dance, theoretical frameworks that emphasize collaboration, such as the “choreomusicking body” and “dance musicalization,” aesthetic approaches to embodiment drawing on treatises like the Natya Sastra and the Abhinaya Darpana, and formal analyses of cine-choreographic “techno-spectacles,” Dancing Women offers a variegated, textured history of cinema, dance, and music. Tracing the gestural genealogies of film dance produces a very different narrative of Bombay cinema, and indeed of South Asian cultural modernities, by way of a corporeal history co-choreographed by a network of remarkable dancing women.

Australian deserts remain dotted with the ruins of old mosques. Beginning with a Bengali poetry collection discovered in a nineteenth-century mosque in the town of Broken Hill, Samia Khatun weaves together the stories of various peoples colonized by the British Empire to chart a history of South Asian diaspora. Australia has long been an outpost of Anglo empires in the Indian Ocean world, today the site of military infrastructure central to the surveillance of 'Muslim-majority' countries across the region. Imperial knowledges from Australian territories contribute significantly to the Islamic-Western binary of the post- Cold War era. In narrating a history of Indian Ocean connections from the perspectives of those colonized by the British, Khatun highlights alternative contexts against which to consider accounts of non-white people. Australianama challenges a central idea that powerfully shapes history books across the Anglophone world: the colonial myth that European knowledge traditions are superior to the epistemologies of the colonized. Arguing that Aboriginal and South Asian language sources are keys to the vast, complex libraries that belie colonized geographies, Khatun shows that stories in colonized tongues can transform the very ground from which we view past, present and future.

Northeast India is situated at the nexus of the South Asian, Southeast Asian, and East Asian biogeographical realms and harbours diverse biota, providing a unique opportunity to archaeologists and anthropologists for the study of the relationship between humans and their environment over the ages. Moreover, this region, the abode of diverse ethnic groups with diverse cultures and customs, hints at a long history of continuous and close association between humans and nature, which is important in the understanding of plant and animal domestication. Genetic analysis of present-day domesticates with their wild counterparts provides valuable insights into their differentiation, time of domestication, and changes in their morphological traits through control by humans. The chapter also elucidates the role played by rice in Northeast Indian culture and highlights the long-term history of rice agriculture in the region.

Karst Waters

Human activities and natural factors determine the hydrogeochemical characteristics of karst groundwaters and their use as drinking water. This study assesses the hydrogeochemical characteristics of 14 karst water sources in the Apuseni Mountains (NW Romania) and their potential use as drinking water sources. As shown by the Durov and by the Piper diagrams, the chemical composition of the waters is typical of karst waters as it is dominated by HCO3− and Ca2+, having a circumneutral to alkaline pH and total dissolved solids ranging between 131 and 1092 mg L−1. The relation between the major ions revealed that dissolution is the main process contributing to the water chemistry. Limestone and dolostone are the main Ca and Mg sources, while halite is the main Na and Cl source. The Gibbs diagram confirmed the rock dominance of the water chemistry. The groundwater quality index (GWQI) showed that the waters are of excellent quality, except for two waters that displayed medium and good quality status. The quality of the studied karst waters is influenced by the geological characteristics, mainly by the water–rock interaction and, to a more limited extent, by anthropogenic activities. The investigated karst waters could be exploited as drinking water resources in the study area. The results of the present study highlight the importance of karst waters in the context of good-quality water shortage but also the vulnerability of this resource to anthropogenic influences.

Abstract The restorer Johann Michael von Hermann (1793–1855), famous in the early nineteenth century, has long fallen into oblivion. A recent discovery of his work associated with old master prints at the Staatliche Graphische Sammlung München has allowed a close study of his methods and skills as well as those of his pupil Ludwig Albert von Montmorillon (1794–1854), providing a fresh perspective on the early history of paper conservation. Von Hermann’s method of facsimile inserts was praised by his contemporaries, before Max Schweidler (1885–1953) described these methods in 1938. The present article provides biographical notes on both nineteenth century restorers, gives examples of prints treated by them and adds a chapter of conservation history crediting them with a place in the history of the discipline. In summary, this offers a surprising insight on how works of art used to be almost untraceably restored by this team of Munich-based restorers more than 150 years before Schweidler.

The Impact

The present study aims to use behavioral responses of the freshwater planarian Girardia tigrina to assess the impact of anthropogenic activities on the aquatic ecosystem of the watershed Araguaia-Tocantins (Tocantins, Brazil). Behavioral responses are integrative and cumulative tools that reflect changes in energy allocation in organisms. Thus, feeding rate and locomotion velocity (pLMV) were determined to assess the effects induced by the laboratory exposure of adult planarians to water samples collected in the region of Tocantins-Araguaia, identifying the sampling points affected by contaminants. Furthermore, physicochemical and microbiological parameters, as well as the presence of inorganic compounds (dissolved aluminum, total barium, total chloride, dissolved iron, total fluoride, total manganese, nitrates, nitric nitrogen, total sulfate, total zinc) and surfactants, were determined on each specific sampling point. The behavioral biomarkers (feeding rate and pLMV) of the freshwater planarians were significantly decreased when organisms were exposed to water samples from four municipalities (Formoso do Araguaia, Lagoa da Confusão, Gurupi and Porto Nacional), sites of the Tocantins-Araguaia hydrographic region—TAHR. Both behavioral biomarkers decreased up to ~37–39% compared to organisms in ASTM medium only. Our results showed that these behavioral biomarkers can be used for fast screening monitoring of environmental samples of freshwater ecosystems, since a decrease in feeding rate and locomotor activity was observed in sites impacted by anthropogenic activities. However, the absence of effects observed in some sampling points does not represent the absence of contamination, since several other classes of contaminants were not determined. In these negative results, the absence of deleterious effects on behavioral biomarkers might only be indicative that the potential presence of contaminants on such sites does not significantly affect the performance of planarians. This fast screening approach seems to be useful to determine contaminated sites in freshwater ecosystems for biomonitoring purposes. This knowledge will help to develop biomonitoring programs and to decide appropriate sampling sites and analysis.

Abstract Freshwater habitats and organisms are among the most threatened on Earth, and freshwater ecosystems have been subject to large biodiversity losses. We developed a Climate Change Sensitivity (CCS) indicator based on trait information for a selection of stream- and lake-dwelling Ephemeroptera, Plecoptera and Trichoptera taxa. We calculated the CCS scores based on ten species traits identified as sensitive to global climate change. We then assessed climate change sensitivity between the six main ecoregions of Sweden as well as the three Swedish regions based on Illies. This was done using biological data from 1, 382 stream and lake sites where we compared large-scale (ecoregional) patterns in climate change sensitivity with potential future exposure of these ecosystems to increased temperatures using ensemble-modelled future changes in air temperature. Current (1961~1990) measured temperature and ensemble-modelled future (2100) temperature showed an increase from the northernmost towards the southern ecoregions, whereas the predicted temperature change increased from south to north. The CCS indicator scores were highest in the two northernmost boreal ecoregions where we also can expect the largest global climate change-induced increase in temperature, indicating an unfortunate congruence of exposure and sensitivity to climate change. These results are of vital importance when planning and implementing management and conservation strategies in freshwater ecosystems, e.g., to mitigate increased temperatures using riparian buffer strips. We conclude that traits information on taxa specialization, e.g., in terms of feeding specialism or taxa having a preference for high altitudes as well as sensitivity to changes in temperature are important when assessing the risk from future global climate change to freshwater ecosystems.
