Abstract:
... Seagrass bed habitat is an important biotic community in decline worldwide. Boat damage has long been recognized for its negative impacts on shallow-water seagrass beds, with those along the Florida coast particularly vulnerable in the face of a large human population possessing a large number of boats. Boat scars to seagrass beds recover slowly, resulting in new damage that often outpaces recover ...

Abstract:
... Twenty-two sites were monitored in the Lower Sassandra River Basin (Côte d'Ivoire, West Africa) to examine patterns in fish species assemblage structure along environmental gradients. Hierarchical clustering of the species presence-absence data identified four types of assemblages corresponding to the man-made Lake Buyo, the main channel, and the two major tributaries. Canonical Correspondence Ana ...

3. Managing Invasive Aquatic Plants in a Changing System: Strategic Consideration of Ecosystem Services

Subject:
Hydrilla verticillata; Phragmites australis; anthropogenic activities; aquatic plants; climate change; coasts; community structure; ecosystem services; ecosystems; grasses; habitat destruction; invasive species; plant communities; salt marshes; vigor
Abstract:
... Climate change is projected to increase stress for many coastal plant communities. Along large portions of the North American coast, habitat degradation from anthropogenic changes to the environment already threaten the community structure of tidal marshes and submerged aquatic grass beds. The potential loss of ecological services historically provided by these communities has been a long-standing ...

coastal water; plant communities; land use change; anthropogenic activities; environmental impact; Halophila; aquatic plants; water temperature; sediments; biomass; light intensity; satellites; sediment transport; deforestation; environmental monitoring; Malaysia
Abstract:
... Seagrass meadows are susceptible to coastal environmental impacts and serve as early indicators of system-wide degradation. Two SeagrassNet monitoring sites were established in Sabah (Malaysia) in 2001 in the Tunku Abdul Rahman National Park: one a pristine, reference site and one anticipating impacts from nearby, ongoing waterfront development. At both sites, percent cover of all seagrass species ...

Abstract:
... The tank cascade system (TCS) in Sri Lanka is one of the most advanced water-conveyance mechanisms among the medieval hydraulic civilizations in the world. In this study, temporal and spatial variations of the hydrogeochemistry of a small cascade system were investigated. A cascade system at Malagane in the Deduru Oya basin, located in the north-west of Sri Lanka, was selected. Measurements of pH, ...
