El objetivo de este trabajo es analizar la percepción de la población en riesgo de vulnerabilidad socioambiental ante fenómenos del cambio climático (epidemias, lluvias intensas, sequías, erosión, inundaciones, huracanes, incremento de la
temperatura, elevación del nivel medio del mar) en la zona urbana de la Ciudad del Carmen, en Campeche. Ante es...
The coexistence of marine sensitive areas with the oil industry requires robust preparedness and rapid response capabilities for monitoring and mitigating oil spill events. Scientifically proven satellite-based methods for the visual detection of oil spills are widely recognized as effective, low-cost, transferable, scalable, and operational soluti...
1. Sea turtles are key imperilled species that interact with numerous threats in their
critical in-water and inland habitats, which they occupy along their complex life
cycle. Therefore, analysing these interactions is essential for adapting ongoing
conservation and management actions.
2. The long-term recording of stranded sea turtle individuals a...
Marine turtles inhabit various coastal and marine ecosystems and play significant ecological roles throughout their life cycles. Because of the significant overlap with other species at risk in their geographic ranges, the successful conservation of marine turtles also protects numerous co-occurring species, a phenomenon known as the “umbrella spec...
Mexico is a special place for the conservation of sea turtles, where six of the seven species that exist in the world can be found, including one of the oldest conservation programs of the continent, the National Sea Turtle Conservation Program. Oaxaca in particular is a very important place, with nesting beaches of recognized relevance and coastal...
Within the Gulf of Mexico, five of the seven species of sea turtles are distributed and carry out essential stages of their life cycle. The marine habitats of sea turtles are subject to various threats, including bycatch and boat traffic. The aim of this study was to identify, in the marine portion of Isla Arena, Campeche, sites of use of space for...
Sea turtles are vulnerable to climate change since their reproductive output is influenced by incubating temperatures, with warmer temperatures causing lower hatching success and increased feminization of embryos. Their ability to cope with projected increases in ambient temperatures will depend on their capacity to adapt to shifts in climatic regi...
Sargassum fluitans and S. natans (sargasso) are species of brown floating algae. They are found in the Atlantic, concentrated the Sargasso Sea, and also, since 2011, in the Great Altantic Sargassum Belt (Wang et al., 2019). Floating masses of sargasso offer resting, reproduction and feeding areas for many species (some of economic interest), and se...
A cost-effective particle-tracking model was implemented to study the transport and landing of sargassum in the Mexican Caribbean. Sensitivity analyses were performed to quantify the change in landing percentages varying some model factors: 1) windage factor, 2) the horizontal distribution of sargassum, 3) monthly variability of currents and winds,...
The state of Campeche, Mexico, harbors one of the largest green turtle (Chelonia mydas) rookeries of the Wider Caribbean Region. Since the 1970s, harvesting of this population was common practice, but it has since ceased, and the population is rebounding as a consequence. In this rookery, during the past 37 years (1984–2020), the positive relations...
The need to understand and forecast disasters driven by anthropogenic and natural forces in the Gulf of Mexico and to support management responses to hazardous events led policymakers, scientists, and industry representatives in Mexico to launch an ocean observation and modeling project (2015–2023) aimed at collecting multi-layered baseline informa...
Long-term monitoring programs of species at risk are efficacious tools to assess population changes, evaluate conservation strategies, and improve management practices to ensure populations reach levels at which they can fulfill their ecological roles. For sea turtles, annual nesting beach surveys are the most accessible method to estimating the po...
Marine turtles are of the highest ecological concern in terms of conservation and restoration programs and marine territorial ordering. Marine resource-extracting industries have severe negative impacts on their populations and their habitats. Thus, private industries and decision makers require the best and most robust spatially explicit scientifi...
The complexity of the social, economic, and environmental characteristics of the coastal zone represents a challenge for decision-makers to identify the socio-environmental conditions of sandy beaches and, consequently, the application of effective management measures. In this study, we propose a quantitative three-step approach to meet this need,...
As the biomass of pelagic Sargassum spp. increased across the North Atlantic equatorial recirculation region from 2011 onwards, massive rafts of sargasso appeared in the Western Caribbean in 2015, 2018, 2019, and 2020. These events raised concerns regarding their negative consequences on the environment, local income, and human wellbeing. As adequa...
Antecedentes y Objetivos:
La restauración ecológica se ha centrado en los componentes físicos y vegetales de los ecosistemas, y ha dejado de lado a la fauna silvestre y sus interacciones. Chelonia mydas es un macroherbívoro en peligro de extinción que anida en playas de México y Cuba, e influye en la vegetación costera con aportaciones de materia o...
Planning for marine ecosystems management demands spatially explicit information about structural and functional components, in a tradeoff between including the most taxa and keeping it functional. Sentinel, umbrella, and surrogate taxa are strategic for developing indexes that account for other associated species and contribute to a sustainable ad...
The recent periodic influx of massive quantities of pelagic Sargassum spp. (sargasso) into the Caribbean has posed ecological, social, and economic challenges to the region. Sustainable use of the biomass is crucial to mitigate negative impacts of beached algae. The current uses of sargasso in Mexico are reviewed, and a biorefinery approach is prop...
Terminos Lagoon is the largest coastal lagoon in the southern Gulf of Mexico and is a highly biodiverse and productive system that supports important seagrasses. These key habitats are under significant stress due to anthropic activities around and inside the lagoon. Considering the lack of updated information about their distribution, cover, and e...
Marine turtles are globally endangered species that spend more than 95% of their life cycle in in-water habitats. Nevertheless, most of the conservation, recovery and research efforts have targeted the on-land habitats, due to their easier access, where adult females lay their eggs. Targeting the large knowledge gaps on the in-water critical habita...
The possible fate of pelagic sargassum in the Mexican Caribbean during aug-2018, sep-2018, and apr-2019 is analyzed using a particle-tracking model coupled to diverse datasets of wind [ERA5 reanalysis and the NCEP Climate Forecast System (CFSv2)] and ocean current velocities (HYCOM experiments of high and lower resolution). Advection of particles w...
The Yucatan Peninsula harbors important nesting beaches for the largest hawksbill turtle (Eretmochelys imbricata) populations in the Western Atlantic. Over the last decade, erosion has substantially modified segments of the nesting beach along the coastal zone of Celestun town, Mexico.
