The Caribbean was one of the last regions of the Americas to be settled by humans, but how, when, and from where they reached the islands remains unclear. We generated genome-wide data for 93 ancient Caribbean islanders dating between 3200-400 cal. BP and find evidence of at least three separate dispersals into the region, including two early dispersals into the Western Caribbean, one of which seems connected to radiation events in North America. This was followed by a later expansion from South America. We also detect genetic differences between the early settlers and the newcomers from South America with almost no evidence of admixture. Our results add to our understanding of the initial peopling of the Caribbean and the movements of Archaic Age peoples in the Americas.

Hurricanes can cause extensive long-term damage to small-scale fisheries. Yet, information is scarce on how communities are locally impacted by extreme events in the Caribbean and in other parts of the world. Focusing on an artisanal fishery in Yaguajay, Sancti Spiritus, Cuba, this article explores how artisanal fishers have perceived and responded to the different damages brought about by Hurricane Irma in September 2017 and the inundations associated with Storm Alberto in May 2018. Combining discussions and short interviews carried out pre and post-storms Irma and Alberto, this study identifies major environmental impacts and matching responses. In addition, the article sheds light on the evolution of small-scale fishing communities in Cuba and their current organization. Results show local perceptions of extensive biodiversity loss in terms of mangrove coverage, changes in salinity, and the quality of coastal environments that have affected the composition of captures and fish sizes. As a consequence of these changes, fishers are adjusting their effort and fishing intensity to match perturbations. Findings underscore the need to identify the synergistic relations that may exist between prior environmental degradation and different extreme events such as droughts, hurricanes, and excessive precipitation. The interrelation of these factors may result in compounded aggravated impacts that may unfold over longer temporal scales and not just as a one-time event. Authors conclude by stressing the importance of including the systematic study of extreme events along with local perceptions of ecological change in fishery management plans. Because fishers responses to hazards are based on their experiences and knowledge of the state of coastal and marine habitats, and especially on expectations about what constitutes normal ranges of change, KEYWORDS

Non-technical summary Sharing information between different countries is key for developing sustainable solutions to environmental change. Coastal wetlands in the Gulf of Mexico are suffering significant environmental and human-related threats. Working across national boundaries, this research project brings together scientists, specialists and local communities from Cuba and the USA. While important advances have been made in strengthening collaborations, important obstacles remain in terms of international policy constraints, different institutional and academic cultures and technology. Overcoming these limitations is essential to formulating a comprehensive understanding of the challenges that coastal socioecological systems are facing now and into the future.

The paper aims to study intragroup variation inside the two pre-Columbian Cuban populations: the aceramic Archaic and the ceramic Taino groups, based on their cranial morphology. The latter applied artificial cranial deformation to all its members, so the groups are referred to as “non-deformed” and “deformed” samples here. Studies across different disciplines suggest evidence of cultural and biological diversity inside the non-deformed group, while local variations of applying the deforming device can be responsible for shape variation across the deformed group. Cranial metrics and non-metric cranial traits of the 92 crania of Cuban origin were analyzed, although the sample size varied between the analyses due to the incompleteness of the crania. Geometric morphometrics was applied to the deformed crania to study the shape variation across the sample. Three deformed crania from the Dominican Republic were analyzed together with the deformed Cuban sample to test the variability of the practice between the islands. Principal component analysis and the Mantel test did not reveal any geographic differences in the cranial metric traits. No morphological differences associated with the antiquity of materials could be seen either based on the available data. The principal component analysis of the Procrustes coordinates of the cranial vault outline in the lateral norm revealed continuous variability of cranial shapes from the ones with more flattened frontal and occipital bones to the more curved outlines, which is probably explained by individual variation. Non-metric traits variation revealed bilateral asymmetry in the expression of the occipito-mastoidal ossicles among the deformed crania. In conclusion, the study did not support assumptions about morphological diversity inside the studied samples or proved the impossibility of available craniological data to reflect possible intragroup differentiation at the moment.

La pesca y la agricultura requieren de un gasto de energía elevado, lo cual influye en los estilos de vida de las poblaciones que practican estas actividades. El objetivo del trabajo es comparar composición de la dieta, estado nutricional y actividad física de 19 campesinos y 14 pescadores ocasionales del municipio Yaguajay, Cuba. La frecuencia de consumo semanal de alimentos se obtuvo mediante un cuestionario. Se evaluó el estado nutricional y la actividad física con el cuestionario IPAQ, este último se aplicó a una submuestra, a la cual se le monitoreó su estado nutricional cinco meses después de la evaluación inicial. La dieta de ambos grupos se caracterizó por alto consumo de arroz, frijoles y viandas. El consumo de pescados y vegetales fue mayor en los pescadores. En la segunda medición, los pescadores aumentaron aproximadamente una unidad su porcentaje de grasa corporal, mientras que los campesinos perdieron aproximadamente 1 kg de peso. El 60% de los pescadores realizó actividad física alta y el 40 % media, para los campesinos los valores fueron 88, 9 % y 11,1% respectivamente. Los campesinos practicaban actividad física diaria, mientras que los pescadores pescaban ocasionalmente.A su vez, los pescadores tuvieron una dieta más saludable, aunque fue más frecuente en ellos la obesidad.
