Beta-diversity is a term used to refer to the heterogeneity in the composition of species through space or time. Despite a consensus on the advantages of measuring β-diversity using data on species abundances through Hill numbers, we still lack a measure of temporal β-diversity based on this framework. In this paper, we present the mathematical bas...

Mexico has committed to protecting 30% of its marine territory by 2030 to comply with Target 3 of the Kunming–Montreal Global Biodiversity Framework, adopted during the 15th Conference of the Parties to the Convention on Biological Diversity. In this paper, we demonstrate the feasibility of meeting this commitment by determining the marine extent o...

Abiotic factors and human impact have a considerable influence on reef corals driving their dynamics and distribution. Most studies on coral reefs address only biological variables that cannot alone explain the predominant stressors and processes. For this work, we studied 46 shallow reefs and 48 deep reefs between 2010 and 2013 in the Cuban archip...

Background Despite the great concern triggered by the environmental crisis worldwide, the loss of temporal key functions and processes involved in biodiversity maintenance has received little attention. Species are restricted in their life cycles by environmental variables because of their physiological and behavioral properties; thus, the timing a...

Noticeable within the Mexican Caribbean is the Arrecife de Puerto Morelos National Park (APMNP), a marine protected area established as an essential component for managing and protecting coral reefs. In June 2019, we conducted a survey in eight shallow reef sites of the APMNP with the purpose of applying a coral reef assessment method, based on bio...

The map represents the spatial distribution of benthic habitats in shallow waters of the Mexican Mesoamerican Barrier Reef System, from Cabo Catoche to Xcalak, in an area of 1001 km2, with an average maximum depth of 18 m. The resulting map defined 50 classes generated from the union of benthic cover and submarine relief maps, estimated from the pr...

The boreal forests of the Northern Hemisphere (i.e., covering the USA, Canada and Russia) are the grandest carbon sinks of the world. A significant increase in wildfires could cause disequilibrium in the Northern boreal forest’s capacity as a carbon sink and cause significant impacts on wildlife and people worldwide. That is why the ability to fore...

Sustainable energy is needed globally, and Ocean Thermal Energy Conversion (OTEC) is a possible way to diversify the energy matrix. This article suggests a preliminary selection process to find optimal sites for OTEC deployment on the Mexican coastline. The method comprises the (1) evaluation of the thermal power potential, using daily data (16 yea...

This study aims to estimate, with a climatology perspective, the average seasonal pattern of phytoplankton biomass (SP-PBavg) and its distribution in Bahia Magdalena (Mexico) as a baseline to evaluate PB changes in future studies. This lagoon is in a semi-arid region, lacks river discharges, and channels with vegetation are limited at the north and...

Fortalecer el sistema de monitoreo marino para el apoyo de la toma de decisiones y la aplicación de las políticas públicas para los mares mexicanos, la pesca sustentable y la conectividad ecológica y el manejo integrado del paisaje marino.

In the Mexican Caribbean, 15 marine protected areas (MPAs) have been established for managing and protecting marine ecosystems. These MPAs receive high anthropogenic pressure from coastal development, tourism, and fishing, all in synergy with climate change. To contribute to the MPAs' effectiveness, it is necessary to provide a long-term observatio...

Hurricane Wilma was the most extreme hydro-meteorological event ever to occur in the Caribbean Sea. During its occurrence, the sea surface elevation was recorded close to Puerto Morelos, Quintana Roo, Mexico. The equipment used which features both, acoustical and pressure sensors to measure the water depth, was deployed approximately at a depth of...

Marine protected areas have been established as essential components for managing and protecting coral reefs to mitigate natural and anthropogenic stressors. One noteworthy example within the Mexican Caribbean is the Arrecife de Puerto Morelos National Park (APMNP), where several studies on the coral communities have been carried out since 2006. In...

Beach nourishment is generally seen as the preferred means of rectifying coastal erosion, due to its low environmental impact and natural evolution. The largest beach nourishment project ever carried out in Mexico took place on Cancun beach in 2006, as a response to the most intense hurricane season ever registered in Mexico, in 2005. After Hurrica...

Research about the variability of sand size inside the hopper of a trailing suction dredger has yet to be done, despite its importance for beach nourishment projects. In this study, several samples were taken using different methodologies during dredging for a particular case of beach nourishment on board one dredger. Sampling was carried out with...

The northwestern coast of Cadiz (Spain) presents a variety of coastal engineering and coastal management problems whose solution is not an easy task due to the complexity of the parameters involved. Two cases of dune zone management in this a rea are described in this paper. Punta Candor beach, a very popular recreational area in Rota municipality,...

The goal of our work was to locate and quantify changes that occurred in 66% of the Mexican coastline, based on four land cover maps generated by the Mexican Mangrove Monitoring System (SMMM) of the National Commission for the Knowledge and Use of Biodiversity (CONABIO) for the years 1970/81, 2005, 2010, and 2015. Our results showed overall dominan...

Wave data collected near the Caribbean coast of Mexico were used to study the frequency and directional structure of the wave field that was generated during the passing of 3 hurricanes. The data were recorded with 2 different acoustic wave gauges, which were installed at a depth of about 20 m. These records provided 183 directional wave spectra co...

Predicting the impact of sea-level (SL) rise on coral reefs requires reliable models of reef accretion. Most assume that accretion results from vertical growth of coralgal framework, but recent studies show that reefs exposed to hurricanes consist of layers of coral gravel rather than in-place corals. New models are therefore needed to account for...

This paper aims to highlight the prevailing experiences of Latin America and to clarify what ‘green infrastructure’ entails in addition to describing seven case studies from a range of coastal ecosystems (wetlands, coastal dunes, beaches and coral reefs) at scales varying from local to regional. The case studies are categorised according to their d...

Predicting if reefs can keep pace with future sea-level (SL) rise is problematic because accretion occurs over geological timescales. For example, although meltwater pulses drowned reefs during postglacial SL rise, drowning has also been reported during the mid Holocene, when SL rise was slower and meltwater pulses unlikely. Here we report the disc...

The coastal zones of Latin America have many landforms and environments, including sedimentary cliffs, deeply incised estuaries, headlands, barrier coasts and low lying, muddy coastal plains. These forms will respond differently to the expected changes in climate and associated sea level rise, which may produce coastal erosion in the future. Consid...

A study about mollusk and foraminifera benthonic communities as possible bioclast producers in Varadero beach and surrounding areas was carried out in April 2001. One hundred and six species of mollusks and 12 of foraminifera were inventoried. Mollusk species richness according to Margalef index (5.7 – 9.3) and their density (190.9 – 1228.6 ind....

Sands of Varadero beach are constituted by calcareous macroalgae, mollusks and foraminifera. The objective of the present work was to assess the main characteristics of calcareous macroalgae associations in subtidal biotopes of the area. Calcareous algae were identified, and their abundance and calcium carbonate content were estimated. Forty-fiv...
