Coral calcification represents a vital process within coral reef ecosystems, wherein reef-building corals contribute significantly to the physical construction and maintenance of framework. The is related photosynthesis endosymbiotic algae, where light plays crucial role in energetic tradeoffs. However, local stressors have led increased turbidity, subsequently affecting availability, especially nearshore reefs. This study proposes light-driven model designed predict Orbicella faveolata...

Pocilloporids are one of the major reef-building corals in eastern tropical Pacific (ETP) and also most affected by thermal stress events, mainly those associated with El Niño/Southern Oscillation (ENSO) periods. To date, coral growth parameters have been poorly reported Pocillopora species northeastern region Pacific. Monthly annual rates three abundant morphospecies ( P. cf. verrucosa , capitata damicornis ) were evaluated during two periods at a site on coast Mexico. The first period,...

Coral reef ecosystems are continuously degraded by anthropogenic and climate change drivers, causing a widespread decline in biodiversity associated goods services. In response, active restoration methodologies practices have been developed globally to compensate for losses due degradation. Yet, most activities employ the gardening concept that uses coral nurseries, centered easily-accessible reefs, with existing infrastructure, impractical reefs remote locations. Here we evaluate...

Corals display different growth forms as an adaptive response to both local and global environmental conditions. Despite the importance of morphologic variability on corals, calcification rates coral morphotypes have been poorly recorded in Eastern Pacific. The purpose this study was compare annual extension rate (cm yr-1), skeletal density (g cm-3), cm-2 yr-1) tissue thickness (mm) males females colonies three common reef-building Porites lobata; columnar, massive, free-living (corallith)...

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

Abstract Scutellastra mexicana is the largest known patellid limpet species and probably one of most endangered marine invertebrates. The was once distributed along American Pacific coast from Mexico to Peru, but their large size (up 35 cm long) easy accessibility (shallow sublittoral), made it very vulnerable human collection now extinct on mainland Mexican coast. In August 2017, a population this found María Cleofas island, off west‐central (Marías Archipelago, Ocean). This constitutes...

Differences in selective pressures and the energetic cost of gametes gonochoristic corals should vary with sex colony, which may lead to sexual dimorphism. Coral colonies are composed subunits (corallites) that create a complex morphological architecture. If corallite features distinct between sexes, then degree coordinated change among these also (phenotypic modularity). This study tested for dimorphism corallites reef-building coral Porites lobata , gonochoric broadcast spawner, compared...

Introduction: The branching coral Pocillopora is the main reef-building species in Eastern Tropical Pacific (ETP) region. However, their populations have been threatened due to intense effect of thermal-stress events last three decades. As a mitigating response, active restoration strategies developed. it has not possible establish specific protocols along ETP’s reefs.
 Objective: To evaluate efficiency two different substrates (natural vs. artificial), through growth comparison...

Introduction: Coral- reef communities are considered one of the most biodiverse, but also threatened, marine ecosystems, and accelerating loss habitat over past decades warrants active intervention. 
 Objective: The present study demonstrates successful implementation a low-impact restoration technique in three Central Mexican Pacific degraded coral communities, using protocol based on natural fragmentation (“fragments opportunity”) branching Pocillopora spp., abundant primary...

Introduction: The 1997-98 El Niño event caused massive coral bleaching and mortality in the Central Mexican Pacific (CMP). Punta de Mita alone used to harbor more than 30 % of coverage this region, with a mono-specific Pocillopora coverage. 1997-1998 ENSO reducing live < 5 %. Despite being considered region unlikely recover, recent restoration efforts have been implemented rehabilitate community.
 Objective: To assess recovery by analyzing growth survival rates branching species at...

Abstract The capacity of coral reefs to provide ecosystem services is widely recognized, but this ability depends on continued carbonate production within the community. Islas Marías archipelago (21° 29.5′ N–106° 15′ W) subject minimal anthropic pressures. This serves as a model study influence environmental variables [e.g., sea surface temperature (SST), upwelling periods, El Niño‐Southern Oscillation (ENSO) events, and pH] structure aim was evaluate growth parameters, ecological volume,...

The Islas Marías Biosphere Reserve, made up of 4 islands in Pacific waters off central Mexico, supports a large diversity marine life. However, scientific research was restricted for decades by the occupation Isla María Madre Federal Penitentiary Colony Mexico from 1905 to 2019. Aside list coastal fish species published 2011, little has been about biodiversity area. While limited access archipelago may have acted as de-facto reserve, there is evidence that fishing continued both legally...

El desarrollo y el mantenimiento de los arrecifes coralinos depende del balance entre la producción (acreción) remoción (erosión) CaCO3 generado principalmente por corales hermatípicos. material calcáreo puede ser removido esqueleto coral agentes físicos, químicos o biológicos, este último es mayor influencia. Pese a su importancia, pocos estudios han estimado tasa bioerosión en comunidades coralinas costa mexicana Pacífico. En estudio se determinó volumen porcentaje vía erosión biológica...

The high diversity and biomass of organisms associated with coral communities depend directly on the maintenance or changes in benthic composition. Over a decade, we evaluated spatiotemporal variation structure composition an insular community Northeastern Tropical Pacific. Our results show that local conditions drive differences, such as sponges, crustose coralline algae, octocorals, hydrocorals all increased abundance (cover) response to negative thermal anomalies caused by 2010–2011 La...

Los corales masivos del género Orbicella son organismos clave que ayudan a mantener la estructura física de los arrecifes coral Caribe. Sin embargo, estos están actualmente amenazados por cambios ambientales, como el aumento nutrientes y contaminación, cuales afectan las características ópticas agua mar y, en consecuencia, limitan su desarrollo. Por lo tanto, analizar respuesta especies relación crecimiento ante ambientes lumínicos nos puede ayudar mejorar estrategias mitigación conservación...

Introduction: Hermatypic corals have the capacity to construct physical reef-framework and maintain balance of coral reef functionality. However, in past three decades, communities been menaced by natural anthropic pressures, resulting an abrupt cover decline, slow recovery. To mitigate collapse, assisted restoration techniques has implemented improved worldwide, long-term effects such interventions on ecological attributes scarcely reported. 
 Objective: This study evaluated effect...

Introducción: El mantenimiento de las comunidades coralinas depende directamente la capacidad los individuos para crecer como colonia. Dado que el crecimiento forma base estructura física del arrecife, determinar tasa especies corales constructores y su respuesta a variaciones ambientales nos permitirá identificar potencial particular implementar estrategias restauración más efectivas.
