Identifying sources of nitrogen to Hanalei Bay, Kauai, utilizing the nitrogen isotope signature of macroalgae.
Sewage effluent, storm runoff, discharge from polluted rivers, and inputs of groundwater have all been suggested as potential sources of land derived nutrients into Hanalei Bay, Kauai. We determined the nitrogen isotopic signatures (delta(15)N) of different nitrate sources to Hanalei Bay along with the isotopic signature recorded by 11 species of macroalgal collected in the Bay. The macroalgae ...
متن کاملIdentifying the Sources of Nitrogen to Hanalei Bay, Kauai Utilizing the Nitrogen Isotope Signature of Macroalgae
Class of 2006 Human Biology In Hawaii, land-use practices on shore have resulted in nutrient loading. This has been cited as a main factor in altering Hawaiian reef ecosystems. However, the source and fate of land-based nutrient loading is not well understood in locations where the impact of pollution is a relatively recent phenomenon, such as Hanalei Bay, Kauai. Here, the source and distributi...
متن کاملResponses of coral reefs and reef organisms to sedimentation
Unprecedented development along tropical shorelines is causing severe degradation of coral reefs primarily from increases in sedimentation. Sediment particles smother reef organisms and reduce light available for photosynthesis. Excessive sedmentation can adversely affect the structure and function of the coral reef ecosystem by altering both physical and biological processes. Mean sediment rat...
متن کاملThirty years of coral reef change in relation to coastal construction and increased sedimentation at Pelekane Bay, Hawaiʻi
Coral reefs are being critically impacted by anthropogenic processes throughout the world. Long term monitoring is essential to the understanding of coral reef response to human impacts and the effectiveness of corrective management efforts. Here we reevaluated a valuable coral reef baseline established in Pelekane Bay, Hawai'i during 1976 and subsequently resurveyed in 1996. During this time i...
متن کاملEcological Processes and Contemporary Coral Reef Management
Top-down controls of complex foodwebs maintain the balance among the critical groups of corals, algae, and herbivores, thus allowing the persistence of corals reefs as three-dimensional, biogenic structures with high biodiversity, heterogeneity, resistance, resilience and connectivity, and the delivery of essential goods and services to societies. On contemporary reefs world-wide, however, top-...
