Abundance and Distribution Patterns of Thunnus albacares in Isla del Coco National Park through Predictive Habitat Suitability Models
2016
Information on the distribution and habitat preferences of ecologically and commercially important species is essential for their management and protection. This is especially important as climate change, pollution, and overfishing change the structure and functioning of pelagic ecosystems. In this study, we used Bayesian hierarchical spatial-temporal models to map the Essential Fish Habitats of the Yellowfin tuna (Thunnus albacares) in the waters around Isla del Coco National Park, Pacific Costa Rica, based on independent underwater observations from 1993 to 2013. We assessed if observed changes in the distribution and abundance of this species are related with habitat characteristics, fis…
Reconstructing the deep population history of Central and South America
2018
We report genome-wide ancient DNA from 49 individuals forming four parallel time transects in Belize, Brazil, the Central Andes, and the Southern Cone, each dating to at least ∼9,000 years ago. The common ancestral population radiated rapidly from just one of the two early branches that contributed to Native Americans today. We document two previously unappreciated streams of gene flow between North and South America. One affected the Central Andes by ∼4,200 years ago, while the other explains an affinity between the oldest North American genome associated with the Clovis culture and the oldest Central and South Americans from Chile, Brazil, and Belize. However, this was not the primary sou…
Hydrology Affects Environmental and Spatial Structuring of Microalgal Metacommunities in Tropical Pacific Coast Wetlands
2016
The alternating climate between wet and dry periods has important effects on the hydrology and therefore on niche-based processes of water bodies in tropical areas. Additionally, assemblages of microorganism can show spatial patterns, in the form of a distance decay relationship due to their size or life form. We aimed to test spatial and environmental effects, modulated by a seasonal flooding climatic pattern, on the distribution of microalgae in 30 wetlands of a tropical dry forest region: the Pacific coast of Costa Rica and Nicaragua. Three surveys were conducted corresponding to the beginning, the highest peak, and the end of the hydrological year during the wet season, and species abun…
Revista española de educación comparada
2016
Monográfico con el título: “La educación en América Latina hoy” Resumen basado en el de la publicación Título, resumen y palabras clave también en inglés Se aborda una comprensión de la infancia centroamericana y su derecho a la educación desde los enfoques de Derechos Humanos y de Capacidades de Sen y Nussbaum. Así, partiendo de las premisas de que niños, niñas y adolescentes son sujetos de derechos; la infancia constituye una etapa con identidad propia, clave en el desarrollo de las personas y la educación es un derecho humano fundamental, se profundiza en el establecimiento y estudio de diversos escenarios educativos en los países centroamericanos y en el impacto de las desigualdades de …
Worldwide trends in body-mass index, underweight, overweight, and obesity from 1975 to 2016: a pooled analysis of 2416 population-based measurement s…

© 2017 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults. Methods We pooled 2416 population-based studies with measurements of height and weight on 128·9 million participants aged 5 years and older, including 31·5 million aged 5–19 years. We used a Bayesian hierarchical model …
Characterisation of Lymnaea cubensis, L. viatrix and L. neotropica n. sp., the main vectors of Fasciola hepatica in Latin America, by analysis of the…
2007
Although, in the endemic areas throughout the world, human fascioliasis presents varying patterns in its epidemiology, the species of lymnaeid snail that act as intermediate hosts and vectors are always crucial in the transmission of the causative parasites. Species in the Galba/Fossaria group of snails, such as Lymnaea cubensis, L. viatrix var. A ventricosa, L. viatrix var. B elongata and Galba truncatula, appear to be frequently involved in the transmission of Fasciola hepatica in Central and South America, although specific classification within this morphologically and anatomically confusing group is often very difficult. To explore the potential use of molecular analyses in the identif…
Reframing Central American Migration From Narrative Journalism
2018
Over the past decade, some journalists and media have addressed Central American migration to the United States from an investigative and narrative reporting perspective, providing a more reliable and accurate portrait of the main characters and their underlying reasons for making the move. This article examines how an ethnographic and analytical approach in combination with narrative techniques can improve the coverage of complex issues such as migration, providing more detailed and complete information than conventional media presents. The qualitative analysis focuses on five projects, including the crossmedia On the Road—with a long-form reportage, a book of photographs, and a documentar…
¿Habrá moros en la costa? La producción cultural centroamericana leída desde España / Would there be Moors on the Coast? Central American Cultural Pr…
2017
Resumen: La literatura centroamericana hizo su aparición en la península española cuando Rubén Darío viajo hacia Madrid en 1892. París y Madrid se convirtieron en las metrópolis culturales de Centroamérica a partir de esa fecha. Sin embargo, su pertenencia a la región no fue reconocida como tal. En España esta producción fue leída desde una perspectiva hispano-céntrica que le fue útil a la península para resolver sus propias contradicciones de legitimación en el seno de Europa. En consecuencia, los escritores centroamericanos que publican con éxito en la península no pueden ser centroamericanos y cosmopolitas a la vez. En España se transforman en “hispanoamericanos.” Lo anterior elide su ce…
Networks to State Capture: Business Elite Networks and Mechanisms of Corporate State Capture in Central American Countries
2017
This paper aims to find out what configuration of business elite networks enables corporate state capture. To achieve this goal, it first uncovers and analyses business elite networks through interlocking directorates in three Central American countries using network analysis, and second, analyses the relationship between business elite networks and the mechanisms that enable corporations to capture states: namely revolving doors and the funding of political parties in the 2014 elections. Findings indicate that when some of the business elites configure a large and cohesive networked business community, while the rest is fragmented, corporate state capture is more likely to occur, as in the…
