Protected areas (PAs) are currently the cornerstones for biodiversity conservation in many regions of the world. Within Africa's moist forest areas, however, numerous PAs are under significant threats from anthropogenic activities. Adequate technical and human resources are required to manage the wildlife within PAs satisfactorily. SMART (Spatial M...

Dengue is a viral disease transmitted by mosquitoes. The rapid spread of dengue could lead to a global pandemic, and so the geographical extent of this spread needs to be assessed and predicted. There are also reasons to suggest that transmission of dengue from non-human primates in tropical forest cycles is being underestimated. We investigate the...

Yellow fever is transmitted by mosquitoes among human and non-human primates. In the last decades, infections are occurring in areas that had been free from yellow fever for decades, probably as a consequence of the rapid spread of mosquito vectors, and of the virus evolutionary dynamic in which non-human primates are involved. This research is a p...

Dengue and yellow fever have complex cycles, involving urban and sylvatic mosquitoes, and non‐human primate hosts. To date, efforts to assess the effect of climate change on these diseases have neglected the combination of such crucial factors. Recent studies only considered urban vectors. This is the first study to include them together with sylva...

Climate change may increase the risk of dengue and yellow fever transmission by urban and sylvatic mosquito vectors. Previous research primarily focused on Aedes aegypti and Aedes albopictus. However, dengue and yellow fever have a complex transmission cycle involving sylvatic vectors. Our aim was to analyze how the distribution of areas favorable...

Climate change may increase the risk of dengue and yellow fever transmission by urban and sylvatic mosquito vectors. Previous research primarily focused on Aedes aegypti and Aedes albopictus. However, these diseases involve a complex transmission cycle in which sylvatic vectors are also involved. Our aim was to analyse which mosquito species could...

La creación de espacios protegidos es una de las herramientas más utilizadas para la conservación de la biodiversidad. Sin embargo, a menudo se desconoce la composición y estado de conservación inicial de algunos de los grupos faunísticos que albergan. En 2018 se aprobó la creación de un nuevo Parque Nacional en Andalucía, el Parque Nacional Sierra...

Dataset with the occurrences of dengue cases from 2013 to 2017. The following information is provided: year, continent, country, admi 1 (largest subnational administrative unit in the country), admi 2 (second largest subnational administrative unit in the country: province, district, municipality or canton), latitude, longitude, and location. The l...

El mono araña marrón (Ateles hybridus) es de particular interés para la conservación por ser un importante dispersor de semillas en el bosque. Por su parte, fue designada como una de las 25 especies de primates más amenazadas del mundo y se encuentra En Peligro Crítico por la destrucción de su hábitat. Su área de distribución más crítica en Venezue...

La encefalitis japonesa, enfermedad causada por un flavivirus, es una de las principales causas de encefalitis viral en Asia. Se registran anualmente unos 67.900 casos, de los que el 30% llegan a ser mortales. La infección es transmitida por mosquitos de la familia Culicidae; los reservorios conocidos son cerdos, aves de la familia Ardeidae y margi...

La distribución de las especies está condicionada por factores ambientales, geográficos, históricos y bióticos. Los modelos de distribución son una herramienta utilizada para establecer las relaciones entre estos factores y la distribución de las especies. La lógica difusa mediante la Función de Favorabilidad, aplicada a los modelos de distribución...

Aim The boundaries of species distributions are often shaped by natural barriers, such as mountains and rivers, but species distribution models usually fail to include these constraints. We tested several approaches that include barriers as explanatory variables in species distribution models. Location Africa and South America. Time period Curren...

Las interacciones interespecíficas están condicionadas por el ambiente en el que se desarrollan. Los modelos de distribución de especies basados en la Función de Favorabilidad, aplicando operaciones de lógica difusa, permiten el estudio de las relaciones biogeográficas entre diferentes especies, y entre ellas y su entorno. Esta aproximación es una...

La borreliosis de Lyme es una enfermedad infecciosa causada por espiroquetas del género Borrelia, transmitida al ser humano por garrapatas del género Ixodes. Es una de las enfermedades más prevalentes en el hemisferio norte que tiene en los mamíferos sus principales reservorios, especialmente en los de pequeño tamaño, como los comprendidos por los...

The brown spider monkey (Ateles hybridus) lives in Colombia and Venezuela and is a Critically Endangered species. The objective was to characterize the behavioral pattern of A. hybridus in a forest fragment in dry season in the Forest Reserve Caparo, Venezuela. Records collected every five min were obtained to evaluate the Focal-Animal Sampling. 21...

The brown spider monkey (Ateles hybridus) lives in Colombia and Venezuela and is a Critically Endangered species. The objective was to characterize the diet of A. hybridus, in a forest fragment of the Caparo Forest Reserve, Venezuela. We used the animal-focal continuous recording method for monitoring 316 h. The 21 identified group members fed on 3...
