“…The most imminent anthropogenic threats to coral reefs are nutrient enrichment and increased sedimentation (e.g. Tomascik & Sander 1985, 1987a, b, Rogers 1990, Tomascik 1990, Babcock & Davies 1991. Human disturbances may act synergistically with other disturbances (human or nonhuman) and irreversibly increase damage and mortality on coral reefs.…”

The influence of colony tissue regeneration on growth was studied in the reef-building coral Montastrea annularis (Ellis & Solander, 1786) by buoyant weighing. Experimental corals consisted of a series of cores, 2 cores from each of 20 colonies. One core of each pair was artificially damaged by removing approximately 1 cm2 of tissue and skeleton, the other served as a control for normal growth. Growth was measured as calcification, i.e. mg calcium carbonate production. There was a linear relation between growth and solar radiation. Variation in growth, calculated before the regeneration experiment, was insignificant between cores from the same colony but significantly different between colonies. Growth was reduced in damaged cores when compared to controls. Calcification decreased immediately upon damage and remained reduced during the whole study (56 d). Lesions caused by physical damage did not always close completely. We propose and test a model that describes regeneration in terms of closure of lesions. Thls model includes an asymptote in an exponentially decreasing function. Calcification remained suppressed after regeneration slowed down and lesions were still not completely closed, probably because of the formation of polyps and skeletal features in the new tissue. We suggest regeneration to be fuelled by polyps and tissue directly bordeling the damaged area. Also, successful regeneration depends on the amount of tissue bordering a lesion and not on colony size.

“…Coastal water quality in Puerto Rico has been implied in long-term coral reef decline (Goenaga & Cintrón, 1979;Herná ndez-Delgado & Sabat, 2000; Garcí a-Saí s, Morelock, Castro, Goenaga et al, 2003; Garcí a-Saí s, Appeldoorn, Batista, Bauer et al, 2008;Herná ndez-Delgado, 2005;Ballantine, Appeldoorn, Yoshioka, Weil et al, 2008). Major threats to coastal water quality include high sediment loads (Rogers, 1990), excess nutrient inputs (Tomascik, 1990), marine snow associated to turbid water pulses (Fabricius & Wolanski, 2000), sewage and non-point source pollutants (Bonkosky, Herná ndez-Delgado, Sandoz, Robledo et al, 2009). Recent evidence shows rapidly declining coastal coral reefs from a combination of sewage and eutrophication impacts (Herná ndez-Delgado, Sandoz, Bonkosky, Mattei et al, 2010;Dí az-Ortega & Herná ndez-Delgado, 2014), and from sediment delivery following rainfall and runoff pulse events (Otaño-Cruz, Montañez-Acuña, Torres-López, Herná ndez-Figueroa et al, 2017).…”

“…These factors often create variable chronic anthropogenic stress gradients, usually negatively affecting water quality (Tomascik & Sander, 1985), coral growth rates (Tomascik, 1990), coral disease prevalence (Kaczmarsky, Draud & Williams, 2005;Smith, Nemeth, Blondeau, Calnan et al, 2008), partial colony mortality (Nugues & Roberts, 2003), and coral reef benthic community structure (Fabricius & McCorry, 2006). Current state of coral reef decline represents an increasing threat to coastal communities from climate change and sea level rise (Herná ndez-Delgado, 2015).…”

“…Eutrophication may also foster phytoplankton blooms (Bell, 1992;McComb, 1995;Arhonditsis, Karydis, & Tsirtsis, 2003), harmful algal blooms (Anderson, Glibert, & Burkholder, 2002), rapid macroalgal growth (Naim, 1993), a long-term decline in fisheries productivity (Hodgkiss & Yim, 1995), and a net decline in seagrass (Duarte, 1995;Tomasko, Dawes & Hall, 1996) and coral reef communities (Lapointe & Clark, 1992;Cloern, 2001;Dí az-Ortega & Herná ndez-Delgado, 2014;Duprey, Yasuhara, & Baker, 2016). Corals are particularly susceptible to eutrophication as a result of declining growth rates (Tomascik & Sander, 1985;Tomascik, 1990), reproductive output (Tomascik & Sander, 1987b), larval settlement rates (Tomascik, 1991), increased incidence of diseases (Kaczmarsky, Draud, & Williams, 2005), altered Environmental Management and Sustainable Development ISSN 2164-7682 2017 microbiology (Kline, Kuntz, Breitbart, Knowlton et al, 2006), and increased susceptibility to bleaching (Vega-Thurber, Burkepile, Fuchs, Shantz et al, 2013;Wiedenmann et al, 2013), and mortality (Pastorok & Byliard, 1985), often impacting benthic community structure (Tomascik & Sander, 1987a). These impacts are often confounded with sedimentation effects (Rogers, 1990;Meesters, Bak, Westmacott, Ridgley et al, 1998;Risk, 2014), and can be readily magnified by climate change-related factors (Ateweberhan, Feary, Keshavmurthy, Chen et al, 2013).…”

Unsustainable land uses may result in poor watershed management, increased soil erosion, poorly-planned urban development, increased runoff, and sewage pollution, creating an environmental stress gradient across coastal coral reefs. This study was aimed at: 1) Evaluating water quality within and outside the Canal Luis Peña Natural Reserve (CLPNR), Culebra Island, Puerto Rico; 2) Determining if there was any significant environmental stress gradient associated to land-based non-point source pollution; and 3) Characterizing shallow-water coral reef communities across the gradient.

Understanding the nature and causes of climate variability and change in the tropical oceans-the heat engine of the global climate system-is limited by the relatively short length of instrumental records. Certain massive reef-building corals contain a wealth of historical proxy climate and environmental information locked in their calcium carbonate skeletons. This information is available from living corals that can be up to several hundred years old and from fossil corals, often well preserved after death, for well-dated windows of the more distant past. Continuous, high-resolution (annual to seasonal) information from such corals is provided by a range of measures that include growth characteristics which can document coral responses to unusual environmental conditions and various geochemical tracers whose incorporation into the skeleton is mediated by ambient seawater characteristics. The stable oxygen isotope ratio, δ 18 O, has been the most commonly measured coral environmental tracer and, although reflecting both sea surface temperature and seawater salinity, long records of this variable are providing new insights into interannual (e.g., El Niño-Southern Oscillation), decadal, and longer time-scale variability in the tropical oceans-information not accessible from the instrumental records-which complements other sources of high-resolution proxy climate information (e.g., tree rings, ice cores, documentary records). The contribution of proxy climate records in corals to the global picture of past climates is being enhanced through efforts to reduce the various sources of uncertainty that can confound the interpretation of any source of proxy climate information. 
