Fish diversity (77 species) in the Aghanashini River estuary of the Indian west coast is linked to variable salinity conditions and zones I, II and III for high, medium and low salinity respectively. Zone I, the junction between Arabian Sea and the estuary, had all species in yearly succession - due to freshwater conditions in monsoon to high salinity in pre-monsoon. The medium (zone II) and low (zone III) salinity mid and upstream portions had maximum of 67 and 39 fish species respectively. Maintenance of natural salinity regimes in estuary, among other ecological factors, is critical for its fish diversity.Keywords

The low level, denuded, laterite landscape of coastal Uttara Kannada has a rich diversity of monsoon herbs, including threatened and newly discovered ones. Our study reveals that honey bees congregate on the ephemeral herb community of Utricularias, Eriocaulons and Impatiens during their gregarious monsoon flowering period. Apis dorsata had highest visitations on Utricularias, Impatiens and Flacourtia indica, whereas Trigona preferred Eriocaulons. Laterite herb flora merits conservation efforts as a keystone food resource for the insect community, especially for honey bees.Keywords

Spatio-temporal patterns of four neighbouring river-scapes in the central Western Ghats, India through land-use analyses using temporal remote sensing data (1973, 2018), reveal a decline in evergreen forests (41%) and fragmentation of intact or contiguous forests (60%). Hydro-ecological footprint illustrates that catchment integrity plays a decisive role in sustaining water for societal and ecological needs. This is evident from the occurrence of perennial streams in the catchment dominated by native flora with forest cover greater than 60%, highlighting the riverscape dynamics with hydrological, ecological, social and environmental dimension linkages and water sustainability. This helps in evolving strategies to adopt integrated watershed management to sustain anthropogenic and environmental water demand.Keywords
