Quantifying the condition of Hawaiian coral reefs
(1) This investigation developed and tested descriptive models designed to evaluate coral reef ecological condition based on data developed using the basic techniques most often used in coral reef surveys. (2) Forty-three variables at 184 stations were analysed in order to identify specific factors that are useful metrics for describing reef condition. (3) The common practice of using ‘referenc...
متن کاملHyperspectral Image Analysis of Coral Reefs in the Hawaiian Islands
Concern over the health of coral reef communities has greatly intensified in recent years, particularly with regard to the complex dynamics of global change. The synoptic spatial and temporal monitoring capabilities of remote sensing provide a valuable avenue for evaluating the impacts of local, regional and global change on this important natural resource. Hyperspectral imagery acquired over t...
متن کاملHistorical Reconstruction Reveals Recovery in Hawaiian Coral Reefs
Coral reef ecosystems are declining worldwide, yet regional differences in the trajectories, timing and extent of degradation highlight the need for in-depth regional case studies to understand the factors that contribute to either ecosystem sustainability or decline. We reconstructed social-ecological interactions in Hawaiian coral reef environments over 700 years using detailed datasets on ec...
متن کاملHabitat Associations and Aggregation of Recruit Fishes on Hawaiian Coral Reefs
Associations with structural habitat complexity and the aggregation of individuals lessen the risk of predation, and both are commonly observed for recently settled fishes on coral reefs. On reefs fringing Hawaii Island, such recruits of many fishes, particularly two species of surgeonfishes, exhibited strong affinities for branching finger coral (Porites compressa Dana, 1846), the most structu...
متن کاملBenthic community structure on coral reefs exposed to intensive recreational snorkeling
Chronic anthropogenic disturbances on coral reefs in the form of overfishing and pollution can shift benthic community composition away from stony corals and toward macroalgae. The use of reefs for recreational snorkeling and diving potentially can lead to similar ecological impacts if not well-managed, but impacts of snorkeling on benthic organisms are not well understood. We quantified variat...
