“…From a management and environmental protection perspective, it is necessary to consider and understand key ecological indicators and processes like a functional ecology approach, as well as biological composition (Vora, 1997) and socio-economic components (Tuohy et al, 2022). In general, the current protected fishing areas of PNSAV (Reyna-Gonzaĺez et al, 2014) do not coincide with those with greater functional diversity. The great mobility of fishes implies that any disturbance can be dispersed between reefs that are inside and outside the shelf; differences between depths and FRic paired with low redundancy point towards a fragile ecosystem with high vulnerability.…”

The Parque Nacional Sistema Arrecifal Veracruzano (hereafter called PNSAV) is the largest coral reef extension in the central region of the Gulf of Mexico. These reefs are unique since they have developed near a coastal environment that is directly influenced by the discharges of Veracruz city, the rivers located on the continental shelf, and the port of Veracruz. This study evaluates the functional diversity, in terms of richness, evenness, and divergence, of the PNSAV fish community. We were interested in quantifying any similarities or differences in functional diversity metrics when one examines reef fish assemblages on a single reef or joint reef subsystems; thus, is there a difference based on scale? A total of 297 fish assemblages were observed in seven PNSAV reefs between May 2006 and April 2021. Significant differences were found in the Functional Richness of the assemblages between subsystems, years, and reef-depth interaction, but none were found among the reefs, or between seascapes. The Functional Diversity presented annual mean values between 0.83 (sd= 0.085) and 0.90 (sd= 0.068) and did not show statistical differences between years, seascape, or reefs. In contrast, statistical differences were found between subsystems, and depth level and the seascape-depth interaction. The annual mean Functional Evenness values ranged between 0.34 (sd= 0.128) and 0.44 (sd= 0.060), and significant differences were detected between years, reef, and reefs-depth level interaction, but no difference were found between subsystems. Reef-fish diversity was greater within the north coral reef subsystem than the southern of the PNSAV. There were no overall tendencies for increased functional diversity throughout the time during this study.

“…(1) regulation: protection to the coast, protection from erosion processes, (2) support: habitat and biodiversity maintenance, shelter; (3) cultural: recreation, tourism-recreational activities, and academic and research activities; and (4) Provision: fisheries (Arceo et al, 2010;Reyna-González et al, 2014). The structural complexity is an important element that divers take into consideration when selecting diving sites for recreational purposes (Williams and Polunin, 2000).…”

Characterizing Geomorphology of Mesophotic Coral Reef Ecosystems in the Southwestern Gulf of Mexico: Implications for Conservation and Management

Coral reefs are the most biodiverse ecosystems on earth and are presently experiencing severe declines globally. Shallow coral reef ecosystems (<30 m) have been studied extensively while mesophotic coral ecosystems (MCE) are poorly studied. As a result, MCE are rarely included in marine reserve design and management, despite their ecological importance and connectivity to shallow reefs. In this study, we assessed the fine-scale topographic complexity, a proxy for structural complexity, for a group of coastal coral reefs in a marine park in the southwestern Gulf of Mexico, in depths between 2 and 49 m. We conducted hydrographic surveys using a semi-portable multibeam echosounder system to produce 3D bathymetry digital terrain models (DTM) with a 2.5 m spatial resolution for three submerged bank reefs and two emerging reefs. From these models, descriptive terrain parameters were calculated for each reef, including slope, aspect, curvature, rugosity and ruggedness. Results show that all reefs are predominantly northeast-southwest oriented, with well-defined leeward and windward sides. For the three submerged bank reefs, structural complexity increased with depth. Estimated mean ruggedness and rugosity were highest at 20–40 m depth range on windward side slopes. Emerging reefs showed high structural complexity, particularly at the 25–40 m depth range. We identified a spur and groove zone with maximum ruggedness (0.26) and rugosity (3.17) values, and four channels with steep slopes (68°) and dispersed mounds. We found that at mesophotic depths (>30 m), southern reefs basements from two distinct reefs merge to form a continuous complex. This has important management implications since presently, only 28.7% of this reef complex (mostly shallow areas) are within the existing limits of the marine park’s core zone. Considering the newly recognized importance of MCE, we propose expanding and reshaping the core zone to include the entire reef complex which mostly encompasses MCE with high structural complexity. Our study illustrates the value of semi-portable MBES for marine planning in developing countries and remote poorly studied areas.

“…The reef system is composed of 27 reef structures, four of which are fringing reefs and the rest are platform reefs. It provides important ecosystem services, such as food supply, cultural benefits, and the regulation of atmospheric phenomena (Reyna-González et al 2014); nonetheless, it has been severely impacted by human activities.…”

“…The frequency of these incidents was analyzed by year and the leading causes were classified according to origin (induced or not induced by humans). Three seasons were considered: Nortes (northerly winds, January-April and November-December), rainy y la regulación de fenómenos atmosféricos (Reyna-González et al 2014). Sin embargo, las actividades humanas han repercutido considerablemente en el estado de conservación de este sistema.…”

Historical information was collected on vessel groundings in the Parque Nacional Sistema Arrecifal Veracruzano (Veracruz Reef System National Park, PNSAV) during the periods 1902–1945 and 1970–2010 to generate specific pressure indicators associated with these events. Information on 126 vessel groundings was gathered, and the cause, specific location, season, and type of vessel were analyzed. Three indicators were generated: stranding pressure, annual pressure, and pressure per site. The highest number of vessel groundings occurred in 1925 and on the Anegada de Adentro reef, the most impacted in both periods. The most common causes of strandings were human error and northerly winds (Nortes). Small vessels were the ones that impacted the most against the reefs. The indicators showed that despite technological advances, pressure caused by groundings in PNSAV continues to occur at a medium level. These indicators are relevant for the management of the area in view of the imminent expansion of the port of Veracruz, which will likely lead to increased vessel traffic and a potential increase in vessel groundings.
