Se realizó un estudio exploratorio-descriptivo en el período noviembre de 2024 a enero de 2025, para evaluar, desde una perspectiva perceptual, los factores que condicionan los comportamientos individuales y colectivos de la población afectada por el huracán Oscar en Guantánamo, Cuba, destacando las lecciones aprendidas para la reducción de riesgos de desastres de origen natural bajo el enfoque “Una Salud”. Se aplicaron encuestas a la población y entrevistas a líderes comunitarios, directivos y decisores, para un total de 350 individuos. Se empleó la escala de Likert para evaluar algunas preguntas y se validó la encuesta mediante la prueba de Alfa de Cronbach. Las lecciones aprendidas incluyen la necesidad de fortalecer las viviendas, mejorar los sistemas de alerta temprana y fomentar la educación comunitaria. El estudio concluye que adoptar el enfoque “Una Salud”, integrando la salud humana, animal y ambiental, es esencial para fortalecer la resiliencia comunitaria y reducir los impactos de futuros desastres. La colaboración entre sectores, la preparación adecuada y la educación sobre riesgos son claves para un futuro más seguro y sostenible.
For a better understanding of the kinematics and mechanics of the Oriente transform fault, a left‑lateral boundary along Cuba's southern margin in the Caribbean, we use the seismic records to determine new deviatoric moment tensor solutions by full waveform inversion for 49 earthquakes, magnitude range 6.8 > M > 3.5, along the southeastern coast of Cuba, from 2015 to the end of 2024. We validate our results using 14 events with moment tensors independently determined by other agencies. The moment tensor solutions calculated here, together with 16 historical ones from the gCMT database, highlight the along-strike segmentation of the Oriente fault system, with oblique normal faulting in the Cabo Cruz transtensional step-over, and oblique reverse faulting further east in the Oriente Deep Zone and the transpressional Santiago Deformed Belt. The Oriente fault, though largely strike-slip, may have a small reverse component itself, as exemplified by the November 10, 2024, Mw 6.8 earthquake. The bulk of reverse/oblique faulting earthquakes, however, coincide with the Santiago Deformed Belt, a narrow crustal sliver overthrusting to the south the extended island arc crust of the eastern Cayman Trough and likely bounded to the north by the Oriente fault. The moment magnitudes computed agree well with the local magnitudes for Mw > 4, as expected. For Mw < 4, we find Mw ≈ 0.67 ML, similar to other regions, for instance the Lesser Antilles.
Se registra por primera vez para la flora de Cuba Lobelia christii, una especie rara previamente considerada endémica de La Española. El nuevo registro se basa en fotografías de plantas vivas y un material recolectado en la Sierra Maestra, provincia Granma, Cuba oriental, confirmado mediante la comparación morfológica con el protólogo, materiales tipo y la literatura disponible. La especie se distingue de las restantes Lobelia cubanas por la combinación de hojas elíptico-oblongas a lanceoladas con margen inciso-dentado, cáliz 5-carinado, corola verde amarillenta y anteras completamente glabras. Se presenta una clave para las especies cubanas de Lobelia y una descripción del taxón, a la vez que se designan un lectotipo y un epitipo para el nombre L. christii Urb.
Leptocereus nudiflorus is the most iconic of Cuban cacti, with a distribution in arid coastal areas throughout Cuba. The species has been categorised as Critically Endangered due to the reduction of its habitats, the number of adult individuals and the small area of occupancy of the species. In the present study we conducted a population census of L. nudiflorus throughout Cuba, where we evaluated different aspects of the natural history of the species such as: height, perimeter, density, threats, soil type, type of vegetation, distance to the coast and distance of juveniles to the nearest adult. The climatic niche of the species was also analysed, and the current distribution of individuals was contrasted with those predicted under two climate change scenarios. With the information compiled, the current conservation status of L. nudiflorus was reevaluated and a recovery strategy was proposed. L. nudiflorus has a global population of less than 2,000 adult individuals and 62% are under at least one direct threat. The largest subpopulations of the species are distributed in Varadero and Mais & iacute;- Caleta, where the species reaches its highest densities. The species is mostly distributed within the first 500 meters from the coastline on red soils in mesophytic semi-deciduous forests [a variant of the seasonally dry tropical forest]. Most juveniles of the species were recorded within 100 metres of an adult individual. L. nudiflorus showed differences in climatic-topographic niche between subpopulations, and less than 30% of the individuals recorded in the present study are predicted to occur in areas of climatic suitability by 2050.
