Abstract The freshwater rockpools support high endemic biodiversity but are poorly studied habitats in the Western Ghats biodiversity hotspot. These freshwater rock pools are situated on outcrops at various elevations in the Western Ghats and are composed of different bedrocks such as laterite and basalt. We aimed to analyze the water quality, geographical position based differences in the water chemistry and the role of bedrock in determining the water chemistry of the rock pools. Our study showed a wide range of water quality variables such as pH, conductivity, and ionic contents that attributed to the natural variation. We observed a drastic variation in the anions and cations at low elevation pools. Rock type and precipitation are influencing the ionic concentration, for example, Calcium and Bromide could be attributed to the seasonal precipitation and geomorphology. This documentation of physicochemical properties of the Western Ghats rock pools can form a baseline for further detailed studies.

Batrachochytrium dendrobatidis ( Bd ) is a pathogen killing amphibians worldwide. Its impact across much of Asia is poorly characterized. This study systematically surveyed amphibians for Bd across rocky plateaus in the northern section of the Western Ghats biodiversity hotspot, India, including the first surveys of the plateaus in the coastal region. These ecosystems offer an epidemiological model system since they are characterized by differing levels of connectivity, edaphic and climatic conditions, and anthropogenic stressors. One hundred and eighteen individuals of 21 species of Anura and Apoda on 13 plateaus ranging from 67 to 1179 m above sea level and 15.89 to 17.92° North latitude were sampled. Using qPCR protocols, 79% of species and 27% of individuals tested were positive for Bd . This is the first record of Bd in caecilians in India, the Critically Endangered Xanthophryne tigerina and Endangered Fejervarya cf. sahyadris . Mean site prevalence was 28.15%. Prevalence below the escarpment was 31.2% and 25.4% above. The intensity of infection (GE) showed the reverse pattern. Infection may be related to elevational temperature changes, thermal exclusion, inter-site connectivity and anthropogenic disturbance. Coastal plateaus may be thermal refuges from Bd . Infected amphibians represented a wide range of ecological traits posing interesting questions about transmission routes.

<div><p><em>The Western Ghats, running parallel to the west coast of India between 8° N and 21° N is a prominent feature of the peninsular India. In freshwater biodiversity hotspots like the Western Ghats, no information is available on activates and ecological role of adult aquatic insect in the riparian zone of streams.</em><strong><em> </em></strong><em>Most adult aquatic insects that emerge from streams live briefly in the nearby riparian zone. Adult activities, such as mating dispersal and feeding influence their distribution in the terrestrial habitat. An observation at Kurangani streams, Western Ghats, India has shown that both numbers and biomass of adult aquatic insects are greatest in the near stream vegetation; however, adult insects can be relatively common 1 to 10 feet from the stream. Why because, adult aquatic insects are abundant and they are primary food resource for many riparian insectivores. The role of adult aquatic insects in the riparian zone must be better understood for riparian and aquatic food chain to be complete. </em></p></div>

In a previous paper* I drew attention to the fact that, owing to the peculiar geographical position of Bombay, almost all the “ heat ” thunderstorms which form during the pre-monsoon and the post-monsoon periods over the hills to the east of the Colaba Observatory, between the sea coast and the Western Ghats, develop a westerly movement and pass over the station. When the air has attained a certain state in regard to its moisture content and lapse-rate, these thunderstorms are initiated by the strong instability produced through the heating of the surface layers over the hills by intense insolation. Their westerly movement was explained by means of the schematic diagram given in fig. 4 of the paper mentioned above. There is no definite evidence whether the “ trigger action ” is caused by a kind of katabatic flow down the Western Ghats advancing as a wedge, but such an assumption would not be inconsistent with this schematic diagram.

Over a wide range of nutrient loadings or concentrations shallow lakes appear to have two main alternative states - clear water, macrophyte-dominated and turbid, phytoplankton-dominated, each with numerous detailed variants. This model is reviewed in terms of defining the problem, broad understanding, detailed understanding and wider meaning. For the former two, our information is reasonably good but there are many details yet to be investigated. Some aspects of this are the mechanisms by which plant beds may act as refuges for grazer Cladocera such as daphnids, the role of non-daphnid (plant-associated) Cladocera in grazing phytoplankton, the role of periphyton grazers and the detailed influence of mixed fish communities in predation. Finally it is suggested that the model has analogies in alternative ways of organising human communities and offers guidance in managing future human affairs.
