More than half of the population of Colombia is settled in the Magdalena River basin, resulting in high deforestation rates due to productive activities and urbanisation. Within this scenario of forest loss and ecosystem degradation, it is imperative to record and monitor the biodiversity in order to decrease and mitigate the negative consequences of human activities on species and ecosystems. For six years, we assessed the mammal species richness, abundance and activity patterns in premontane forests of the Magdalena River basin in the Department of Caldas, Colombia. We also presented additional information on the geographical affinities of this fauna. We recorded 101 species, seven of them endemic to Colombia, with Chiroptera being the richest order, followed by Rodentia. Most of the species are common and not listed in threatened categories and only four are vulnerable and two endangered, according to the Red List of the IUCN and the Ministerio de Medio Ambiente y Desarrollo Sostenible of Colombia. The mammalian fauna of the study area is similar to that of other lowland localities in the Neotropics and different to the fauna in highland localities, including the nearby ones. Specifically, this fauna was most similar to that in lowland Tolima and the Caribbean Region of Colombia, Venezuela and Costa Rica; however, when we accounted only for bat fauna, it was more similar to the fauna in Caribbean and Pacific Regions of Colombia. To secure the long-term persistence of these species, we recommend maintenance of the current corridors, such as riparian forests and living fences and an increase in the forested area.
The Magdalena river basin is home to more than half of Colombia’s human population, and consequently the basin also harbors their economic activities. These activities have generated high deforestation rates and negative pressures on natural resources. With such a scenario of forest loss it is imperative to assess the state of the biodiversity and its conservation. Here, during six years we assessed the mammalian species richness and abundance in premontane forests of Caldas department in the Magdalena river basin. We also presented additional information on the activity patterns and geographical affinities of this fauna. We recorded 100 species of mammals with the Chiroptera as the richest order, followed by Rodentia. Most of the species are common and are not under risk of extinction; however, it is important to highlight the presence of six endemic species, three vulnerable species and one endangered species (white-footed tamarin). The mammalian fauna of this region is similar to other lowland localities in the Neotropics, and less similar to highland localities, including the nearby ones. Specifically, this fauna is most similar to lowland Tolima, and the Caribbean region of Colombia, Venezuela and Costa Rica; however, when we accounted only for bat fauna, it was more similar to the Caribbean and Pacific regions of Colombia. To secure the long-term persistence of these species we recommend maintenance of the current corridors such as riparian forests and living fences and an increase in the forested area.
El objetivo del estudio fue evaluar el efecto de una intervención educativa sobre los conocimientos de Equinococosis Quística Humana (EQH) en una escuela rural del nivel primario en Junín - Perú. El estudio de tipo cuasi-experimental se inició con la capacitación de docentes en temas relacionados a EQH, además de una capacitación en elaboración de sesiones de aprendizaje. La intervención educativa se realizó el segundo bimestre educativo del año 2019. Se realizaron tres evaluaciones durante el estudio, al inicio (pre test), al final del bimestre (post test 1) y cuatro semanas después del anterior (post test 2). Los estudiantes de primero a tercer grado fueron evaluados con un instrumento de 5 preguntas y los de cuarto a sexto grado con uno de 10 preguntas. Las notas fueron resumidas mediante medidas de tendencia central y dispersión. La diferencia entre las notas de los test fue evaluada con la prueba de Análisis de Varianza por Rangos de Friedman y la prueba de Rango Signado de Wilcoxon. Los puntajes obtenidos en los diferentes test reportaron efectos positivos de la intervención en los estudiantes de segundo a sexto grado. Solo se encontró diferencia en el puntaje del post test 1 y 2 en estudiantes del tercer grado, siendo menor en el post test 2. Sin embargo, la evaluación del rendimiento global del grado varió para el post test 2 mostrando que la retención de los conocimientos se afectó por el grado de estudio. Se concluye que la aplicación de sesiones de aprendizaje de EQH fue eficiente, pero requieren de refuerzos para perpetuar los conocimientos en el tiempo.
