![]() Otter presence/absence in 78 1 km2 plots across two river catchments was modelled against several habitat variables including measures of agricultural pollution, salinity, mangrove cover, and fishing presence. In the Indian context, there are significant gaps in knowledge pertaining to factors that influence otter occurrence in such environments. This study was aimed to assess habitat selection of threatened smooth-coated otters (Lutrogale perspicillata) in the peri-coastal landscape of Goa, India. However, several species have adapted to thrive in human-modified landscapes. Human development can have detrimental impacts on the environment and its contained ecosystems. Despite ubiquitous increases, variability in conductivity trends across space and time underscores the need for more intensive monitoring as urbanization progresses. Observed patterns may suggest distinct sources and different degrees of hydrologic connection. ![]() All 12 watersheds experienced variable but monotonic increases in impervious cover, which ranged from 13.8%), particularly when conditioned on winter storm events. We used a 25‐year annual time series of impervious cover for the Baltimore‐Washington, DC, metropolitan area to interpret long‐term records from 12 watershed‐monitoring stations in the Mid‐Atlantic Piedmont USA from 1986 to 2010 and explore stream conductivity under progressive urbanization. ![]() Thus, the potential role of stream chemistry in sharp biodiversity losses observed at low levels of urbanization is difficult to distinguish from other concurrent factors such as temperature, flow, or sediment. Although increases are often associated with urbanization, knowledge of chemical dynamics during urbanization is limited and typically drawn from space‐for‐time studies. Long‐term analysis indicates that progressive salinization of freshwaters is widespread.
