abstract = {Subject to hurricane disturbance for millennia, natural ecosystems of Puerto Rico exhibit clear patterns of resistance (e.g., many tree species have little immediate storm-related mortality) and resilience (e.g., leaf litterfall and stream chemistry returned to pre-hurricane levels in as little as five years). Contemporaneous studies of near-shore areas also suggested no long-term impacts of hurricanes; however, anthropogenic effects (coral bleaching, sedimentation) dominate the long-term condition of marine systems in Puerto Rico, many of which have slowly evolved into novel ecosystems. A key characteristic of novel marine ecosystems is their long-term loss of benefits and resilience, coupled to declining biodiversity and loss of structural or functional redundancy, signaling increased vulnerability to subsequent hurricanes. Human systems are also strongly affected by cyclonic storms, as evidenced by the recent impacts of Hurricanes Irma and Maria in the Caribbean. The lack of short-term recovery from disturbance by coral reef ecosystems, coupled with an increasing recurrence of anthropogenic impacts, increasing hurricane frequency or severity, and sea-level rise, may have irreversible long-term socioeconomic consequences for coastal social–ecological systems and for community livelihoods. A comprehensive social–ecological understanding of hurricane effects in Puerto Rico is lacking in part because hurricane effects on human populations are not comprehensively followed. Although some studies suggest a path forward, finding effective methods to link measurements of storm intensity to the diverse components of tropical social–ecological systems remains a challenge.},

abstract = {Timely information is critical for coral reef managers and decision-makers to implement sustainable management measures. A Coral Reef Resilience Index (CRRI) was developed with a GIS-coupled decision-making tool applicable for Caribbean coral reef ecosystems. The CRRI is based on a five-point scale parameterized from the quantitative characterization of benthic assemblages. Separate subindices such as the Coral Index, the Threatened Species Index, and the Algal Index also provide specific information regarding targeted benthic components. This case study was based on assessments conducted in 2014 on 11 reef sites located across 3 geographic zones and 3 depth zones along the southwestern shelf of the island of Puerto Rico, Caribbean Sea. There was a significant spatial and bathymetric gradient (p < 0.05) in the distribution of CRRI values indicating higher degradation of inshore reefs. Mean global CRRI ranged from 2.78 to 3.17 across the shelf, ranking them as “fair.” The Coral Index ranged from 2.60 to 3.76, ranking reefs from “poor” to “good,” showing a general cross-shelf trend of improving conditions with increasing distance from pollution sources. Turbidity and ammonia were significantly correlated to CRRI scores. Multiple recommendations are provided based on coral reef conditions according to observed CRRI rankings.},
