“…In an assessment of the restored Bay of Carrizales, located 7 km from the study area, all four hues of the CoralWatch scale were found in the coral community. Likewise, changes were observed in hues of wild populations with respect to the time of year; organisms undergoing restoration were unchanged from their original hues (E and B) (Liñán-Cabello et al, 2011).…”

“…This widely used method was previously applied in the study area to evaluate the status of coral populations of Pocillopora spp. (Liñán-Cabello et al, 2011). In the present work, coral color was evaluated in situ and compared to the Cor-alWatch chart, which identifies four basic coral morphotypes that facilitate the evaluation of coral hue (four series, B-E), each divided into six color fields (1-6), ranging from near-white to dark brown.…”

“…In the present work, coral color was evaluated in situ and compared to the Cor-alWatch chart, which identifies four basic coral morphotypes that facilitate the evaluation of coral hue (four series, B-E), each divided into six color fields (1-6), ranging from near-white to dark brown. Each color square on the chart was related to the density of zooxanthellae, an important indicator of coral health and thus the health of the entire reef (Siebeck et al, 2006), according to previous studies that have tested density of symbiont vs color in the Eastern Pacific (Liñán-Cabello et al, 2011;Marshall, Kleine, & Dean, 2012).…”

“…Finally, sedimentation on coral structures was examined at each sampling station by two placing settlers with a surface area of 200 cm 2 , at a depth range of 0.70-1.50 m (Liñán-Cabello et al, 2011). These collectors were placed at each transect area for periods of 15 days to a month, from September 2011 to January 2012.…”

Coral reef ecosystems are under stress of different origins, from factors including sedimentation, fragmentation, overfishing, and tourism, depending on their geographical location, depth, and proximity to recreation areas. In this study of Juluapan Lagoon, we examined the relationship between various water-quality attributes and the status indicators of the coral community at La Boquita reef. During 2011 (12 months of sampling), six monitoring stations in the Juluapan lagoon were established in order to observe the gradient of the distribution of the physicochemical parameters: three stations on the upper part, or BI, (S4 to S6) and three more in the lower part, or BII, (S1 to S3). A control station (CS) was located in the coral reef close to the lagoon channel, and where dissolved inorganic nutrients and cellular carbon content were determined. Additionally, we considered the monitoring of three of the eight largest coral structures/headlands of this community: the first was the station closest to the channel communicating with Juluapan lagoon (C1), the second was in the intermediate region with respect to that lagoon (C2), and the third was farthest from the channel (C3). Three line intercept transects (LIT) 30 m in length and perpendicular to the coast provenance were established in each station, and the parameters indicative of the status of corals were evaluated in an area of 60 m2 on each transect (180 m2 by the station). Turbidity, evidence of fishing, signs of settling, algal coverage, abundance of fish, rate of sediment, and coral health records (as for CoralWach chart) were determined in situ and from digital photographs and videos. Considering various community status indicators used in the reef area, we could recognize a state of general deterioration, which was reflected in the loss of 17 % of coral coverage. The main anthropogenic disturbances in adjacent areas to La Boquita reef included wastewater discharges into the lagoon, tourist developments in the coastal zone, deforestation and erosion resulting from inappropriate development, and the runoff of nutrients from agricultural lands nearby the lagoon. All these significantly contributed to the nutrient-enriched waters of the lagoon, especially in summer, with negative effects on the coral community. Continued exposure to these factors, coupled with the lack of control over other anthropogenic components, has promoted the maintenance of a chronic stress state in the studied coral community. Our findings highlight the need for the development of appropriate coastal management and conservation policies for the coral reefs of the Mexican Pacific Coast.

“…En estas comunidades imperan corales hermatípicos de 3 principales géneros: Pocillopora, Porites y Pavona, siendo el primero de ellos el de mayor abundancia, representado fundamentalmente por las especies Pocillopora verrucosa, P. capitata y P. damicornis (Reyes-Bonilla et al 2013). No obstante, estos ambientes coralinos comparten una problemática relacionada con la degradación y pérdida de cobertura coralina, como consecuencia de diversas presiones de origen antropogénico (presión turística, sedimentación, sobrepesca, trasformación de la línea costera) (Liñán-Cabello et al 2011). Dentro de los trabajos científicos orientados a la restauración de Pocillopora spp.…”

Abstract.-During a restoration process of Pocillopora spp., using opportunity corals (CO) several biotic attributes were assessed at two sites bi-monthly over a year and concentrations of mycosporin type amino acids (MAAs) and levels of chlorophyll a (Chl a) were determined. Specifically, in the last sampling analysis it was performed an analysis of malonaldehyde (MDA) and the RNA/ DNA and protein/DNA relationships were calculated, as an index of oxidative stress and transcriptional activity in symbiont and coral tissue of all morphotypes. At Carrizales site (SC) the coral clusters (RC) used as a method of restoration, promoted the integration of CO showing signs of recovery and high survival rates (90%); however, in Juluapan site (SJ), a lack of response to biotic and molecular indicators associated with recovery was observed. Therefore, CO from Carrizales were not able to acclimate to a place where different conditions prevail. High concentrations of Chl a, AAMs and a high RNA/DNA ratio were characteristic of a healthy condition of coral which in turn, were associated with higher specimen's survival and restoration.Key words: Restoration, Pocillopora, calcareous algae, coral, oxidative stressResumen.-Durante un proceso de restauración de Pocillopora spp., usando corales de oportunidad (CO), fueron evaluados diversos atributos bióticos en dos sitios a lo largo de un año, de manera bimensual fueron determinadas las concentraciones de aminoácidos tipo micosporina (AAMs) y niveles de clorofila a (Cl a). De manera específica, en el último muestreo se realizó un análisis de malonaldehido (MDA) y se calcularon las relaciones ARN/ADN y proteína/ADN como indicadores de estrés oxidativo y actividad trascripcional en simbionte y cnidario de todos los morfotipos. En sitio Carrizales (SC) la técnica de restauración de ramilletes coralinos (RC) promovió la integración de COs registrando signos de recuperación y altas tasas de supervivencia (90%); no obstante, en el Sitio Juluapan (SJ), se observó una falta de respuesta a los indicadores bióticos y moleculares asociados a la recuperación. Por lo tanto, los CO provenientes de Carrizales no fueron capaces de aclimatarse a un sitio en el que imperan distintas condiciones ambientales. Altas concentraciones de Cl a, AAMs, y una alta relación ARN/ADN fueron características de una condición saludable de corales, que a su vez, estuvieron asociados a los indicadores de restauración y mejor supervivencia observada.

The nature of the pigments in octocorals has been investigated by Raman spectroscopy, where laser excitation at 632.8 and 1064 nm were used to characterize the colored components present in the skeleton of the exotic pink-yellow soft coral Chromonephthea braziliensis, the reddish purple sea fan Leptogorgia punicea and the endemic deep violet red Leptogorgia violacea from the southeastern coast of Brazil. The observed positions of two major Raman bands at ca 1500 cm −1 [ν(C C)] and 1130 [ν(C-C)] for all specimens strongly suggest the presence of a mixtureof conjugated polyenes belonging to a class of compounds named parrodienes. The hemiketal steroidal feeding deterrent, 23-keto-cladiellin-A, isolated from C. braziliensis was identified in the crude extracts by the Raman analysis using 1064 nm excitation. The observation of the most important vibrational bands of this compound can be useful in future investigations to monitor its presence in crude extracts of C. braziliensis and or other species.
