    La migración es un fenómeno que ha llamado la atención de investigadores a lo largo del mundo y de la historia de la ciencia. Este proceso biológico ha sido bien estudiado en aves, sin embargo, en Colombia y, especialmente en la región de la Orinoquia, aún queda mucho por conocer sobre estas viajeras. Este artículo presenta el fenómeno de la migración Neotropical en aves; primero se evidencia una recopilación de bibliografía sobre la migración en aves y algunos de sus aspectos más relevantes, a continuación se hace un análisis de este fenómeno en la región de la Orinoquia y se proponen pasos a seguir para mejorar el estudio y conservación de estas aves en el país y en la región orinocense. Con este artículo se pretende llamar la atención sobre la importancia de estudiar las aves migratorias en la Orinoquia para diseñar estrategias efectivas para su conservación

    I am honored to present to you this remarkable book, a testament to the invaluable research conducted in the fields of Health, Law, Engineering, and Administrative Sciences. Each chapter within these pages represents the culmination of extensive investigations carried out by dedicated scholars affiliated with the Red Universitaria de Risaralda (RUN), a network comprising 15 esteemed higher education institutions. Risaralda has emerged as a thriving hub for higher education, bolstered by its strategic geographical location, high quality of life, rich biodiversity, and competitive development. Today, Pereira ranks third in the index of university cities, with a student enrollment rate exceeding 63%. Close to 50,000 students pursue academic programs within the department. Notably, three institutions have achieved accreditation for their excellence in education, positioning Risaralda among the most competitive regions in terms of accredited academic programs. As we celebrate the 20th anniversary of the Red Universitaria de Risaralda in 2023, it is with great pride that we reflect on its pivotal role in fostering collaboration among public and private higher education institutions. Our mission has been twofold: attracting students to our region and supporting sustainable development and quality of life for our community. The mesa de investigación (research committee) has diligently coordinated the necessary actions to unite our researchers, facilitating an integrated approach to various disciplines and themes associated with the challenges faced in our region.CONTENT Introduction...................................................................................................................5 CHAPTER ONE.

    Colombia es uno de los países mega diversos del mundo, ocupando el primer lugar en diversidad de aves, el segundo en plantas, y el tercero en mariposas. las tres cordilleras, los tres valles interandinos, las selvas las tierras bajas y las vastas sabanas hacen de nuestro país el escenario ideal para alojar una alta diversidad tropical. como las demás regiones de Colombia, la Orinoquia es una re guion especial y diversa en cuanto a los ecosistemas que posee, y la fauna y flora que alberga. en esta vasta región, abarcada entre la gran cuenca del rió Orinoco, la cordillera oriental de los andes, y las selvas amazónicas encontrando gran variedad de ecosistemas siendo los mas representativos: las sabanas bien drenadas o altillanura, las sabanas inundables, los bosques de galería, los bosques subandinos, los bosques del escudo Guyanés, entre otros

    Elevational Ranges of Montane Birds and Deforestation in the Western Andes of Colombia

    No full text
    Deforestation causes habitat loss, fragmentation, degradation, and can ultimately cause extinction of the remnant species. Tropical montane birds face these threats with the added natural vulnerability of narrower elevational ranges and higher specialization than lowland species. Recent studies assess the impact of present and future global climate change on species' ranges, but only a few of these evaluate the potentially confounding effect of lowland deforestation on species elevational distributions. In the Western Andes of Colombia, an important biodiversity hotspot, we evaluated the effects of deforestation on the elevational ranges of montane birds along altitudinal transects. Using point counts and mist-nets, we surveyed six altitudinal transects spanning 2200 to 2800 m. Three transects were forested from 2200 to 2800 m, and three were partially deforested with forest cover only above 2400 m. We compared abundance-weighted mean elevation, minimum elevation, and elevational range width. In addition to analysing the effect of deforestation on 134 species, we tested its impact within trophic guilds and habitat preference groups. Abundance-weighted mean and minimum elevations were not significantly different between forested and partially deforested transects. Range width was marginally different: as expected, ranges were larger in forested transects. Species in different trophic guilds and habitat preference categories showed different trends. These results suggest that deforestation may affect species' elevational ranges, even within the forest that remains. Climate change will likely exacerbate harmful impacts of deforestation on species' elevational distributions. Future conservation strategies need to account for this by protecting connected forest tracts across a wide range of elevations

    Economic and Conservation Potential of Bird-Watching Tourism in Postconflict Colombia

    No full text
    Ongoing conflict resolution in Colombia brings an opportunity for economic development of impoverished communities and a conservation threat of deforestation in newly accessible rural areas. Ecotourism is often proposed as a “win–win” solution for developing countries to meet both economic and conservation needs. With the highest number of bird species of any country, including 443 rare species highly valued by bird-watchers, Colombia has a unique opportunity to develop a lucrative and conservation-friendly bird-watching tourism industry in postconflict areas. Through geospatial analysis of conflict zones, bird distributions, protected areas, forest cover, and bird-watching activity, we identify areas of Colombia with unrealized bird-watching potential that are ripe for the development of synergistic conservation-ecotourism projects. An investment in ecotourism infrastructure and training by the Colombian government may be a conservation-friendly alternative to natural resource extraction that could alleviate poverty without degrading natural capital in postconflict Colombia.ISSN:1940-082
