“…Moreover, colony calcification of Pavona showed moderate values (13.72 kg m −2 yr −1 ), compared with branching morphologies (Cabral‐Tena et al, 2020; González‐Barrios & Álvarez‐Filip, 2018). Regardless, Pavona and Pocillopora are a relevant species, which represents the most three‐dimensionally complex coral species from the ETP (Cabral‐Tena et al, 2018, 2020). Regional studies of variability in coral morphology are necessary to identify the influence that morphology plays in coral calcification and the function of these corals in their coral reef communities.…”

Hermatypic corals have the potential to construct calcium carbonate (CaCO 3 ) reefframework, maintain habitats tridimensionality and contribute to both the biogeochemical and the geo-ecological functionality of coral reefs. However, in the past decades, coral reef growth capacity has been affected by multiple and cumulative anthropogenic stressors, threating the reef functionality and their ecosystem goods and services provision to humankind. This study evaluated temporal changes in geo-

“…as most ETP reefs are dominated by pocilloporids due to their rapid growth, which confers greater competitive advantages on both ecological and geological time scales (Glynn et al, 2017;López-Pérez, 2017) when compared with those of the massive species that contribute to a lesser extent to the formation of the reef matrix in shallow waters (<10 m; Glynn & Ault, 2000;Reyes-Bonilla & López-Pérez, 2009;Cabral-Tena et al, 2020).

The capacity of coral reefs to provide ecosystem services is widely recognized, but this ability depends on continued carbonate production within the coral community.The Islas Marías archipelago (21° 29.5′ N-106° 15′ W) is subject to minimal anthropic pressures. This archipelago serves as a model to study the influence of environmental variables [e.g., sea surface temperature (SST), upwelling periods, El Niño-Southern Oscillation (ENSO) events, and pH] on the structure of the coral community. The aim of this study was to evaluate the growth parameters, ecological volume, and CaCO 3 production of Pocillopora corals, which comprise the dominant genus in the Eastern Tropical Pacific (ETP). During an annual period (2016-2017), 10 colonies were stained with alizarin red and height, major diameter, and minor diameter measurements were recorded. Live coral cover, the annual extension rate (cm/year), skeletal density (g/ cm 3 ), the calcification rate (g/cm 2 year −1 ), ecological volume (cm −3 ), and carbonate production (kg m −2 year −1 ) were also calculated. The average extension rate (± SD), skeletal density, and the calcification rate were 1.86 ± 0.31 cm/year, 2.28 ± 0.34 g CaCO 3 cm −3 , and 4.34 ± 1.28 g CaCO 3 cm −2 year −1 , respectively. The average live coral coverage was 3.19 ± 3.17%, and the relative cover of Pocillopora corals was 65%.Ecological volume increased 140.6 ± 84.28% with respect to the initial volume, and the average production of CaCO 3 was 0.46 ± 0.41 kg CaCO 3 m −2 year −1 . This study shows evidence of low growth rates, low generation of three-dimensionality, and low CaCO 3 production in the study area when compared to other sites in the ETP. These results are relevant because they indicate compromised long-term maintenance and reef development in Islas Marías, which may result in low reef functionality and compromise the stability of reef-associated biodiversity and ecosystem services.

Introduction: The importance of holothuroids in marine ecosystems is related to their feeding activities, which have been little studied in the eastern Pacific. Objective: To describe the feeding habits of the sea cucumber Holothuria (Stauropora) fuscocinerea and their bioturbation potential in La Entrega reef, México. Methods: The population size of H. (Stauropora) fuscocinerea was determined by means of four 20 x 4 m (320 m2) band transects, while the available sediment for the sea cucumbers and their feces were characterized in three stations (A-C) via granulometry and quantification of organic carbon and organic matter. Excretion rate was determined every 4 hr over a 24 hr period and the relationship between sea cucumber length and biomass and the excretion rate evaluated. Results: According to non-parametric permutation, ordination and percentage similarity analyses, sea cucumber feces mostly comprised a large proportion of small grains compared to the available sediment, indicating that H. (Stauropora) fuscocinerea is selective on grain size. Preliminary bioturbation potential of the species may reach up to 8.71 ± 0.17 kg day of sediment in the study area. Conclusion: The spatial distribution of H. (Stauropora) fuscocinerea in the study area is a product of its selective feeding activity, evidencing the preliminary importance of the species in the trophic dynamics of La Entrega reef.
