Monitoring and M A Record-Breakin Geophysical Mon Copyright 2011 b 10.1029/2011GM On 22–23 June 2010, the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) L band radar imaged the Deepwater Horizon oil spill and the effects of oil that was transported within the Gulf of Mexico. We describe the campaign and discuss the unique contributions of the UAVSAR radar to the study of the detec...

Wetlands include a wide variety of habitats such as marshes, peatlands, floodplains, rivers and lakes coastal areas salt mangroves seagrass beds, but also coral reefs other marine no deeper than 6 m at low tide, well human-made wetlands paddy lands, waste-water treatment ponds reservoirs. According to Ramsar convention the are classified three types viz., coastal/marine wetlands, inland human m...

Water beetles are one of the dominant macroinvertebrate groups in inland waters and are excellent ecological indicators, reflecting both the diversity and composition of the wider aquatic community. The predaceous water beetles (Hydradephaga) make up around one-third of known aquatic Coleoptera and, as predators, are a key group in the functioning of many aquatic habitats. Despite being relativ...

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expresse...

The coastal lands of southern Kerala, SW India in the vicinity of Achankovil and Thenmala Shear Zones reveal a unique set of geomorphic features like beach ridges, runnels, chain of wetlands, lakes, estuaries, etc. The chain of wetlands and water bodies that are seen in the eastern periphery of the coastal lands indicates the remnants of the upper drainage channels of the previously existed coa...

Nepal houses only inland freshwater wetlands, ranging from floodplains of snow-melt-fed cold Himalayan rivers, warm rivers originating in the mid hills, high altitudinal glacial lakes to hot springs, ponds, ox-bow lakes, marshes and swamps. These wetlands support several endemic and globally threatened species of flora and fauna. Besides, wetland sites have significant recreational, religio-cul...

Wetlands are highly productive ecosystems that host unique biota and provide vital ecosystem services. Despite their critical importance, we still lack a fundamental understanding of factors controlling species suitability climate change impacts in wetlands essential to conserving these imperiled the face anthropogenic threats. Here, applied ecological niche models (ENMs) inferred from massive ...
