    La migraci贸n es un fen贸meno que ha llamado la atenci贸n de investigadores a lo largo del mundo y de la historia de la ciencia. Este proceso biol贸gico ha sido bien estudiado en aves, sin embargo, en Colombia y, especialmente en la regi贸n de la Orinoquia, a煤n queda mucho por conocer sobre estas viajeras. Este art铆culo presenta el fen贸meno de la migraci贸n Neotropical en aves; primero se evidencia una recopilaci贸n de bibliograf铆a sobre la migraci贸n en aves y algunos de sus aspectos m谩s relevantes, a continuaci贸n se hace un an谩lisis de este fen贸meno en la regi贸n de la Orinoquia y se proponen pasos a seguir para mejorar el estudio y conservaci贸n de estas aves en el pa铆s y en la regi贸n orinocense.

    Accurate maps of species ranges are essential to inform conservation, but time-consuming to produce and update. Given the pace of change of knowledge about species distributions and shifts in ranges under climate change and land use, a need exists for timely mapping approaches that enable batch processing employing widely available data. We develop a systematic approach of batch-processing range maps and derived Area of Habitat maps for terrestrial bird species with published ranges below 125,000 km2 in Central and South America. (Area of Habitat is the habitat available to a species within its range.) We combine existing range maps with the rapidly expanding crowd-sourced eBird data of presences and absences from frequently surveyed locations, plus readily accessible, high resolution satellite data on forest cover and elevation to map the Area of Habitat available to each species. Users can interrogate the maps produced to see details of the observations that contributed to the ranges. Previous estimates of Areas of Habitat were constrained within the published ranges and thus were, by definition, smaller-typically about 30%. This reflects how little habitat within suitable elevation ranges exists within the published ranges. Our results show that on average, Areas of Habitat are 12% larger than published ranges, reflecting the often-considerable extent that eBird records expand the known distributions of species. Interestingly, there are substantial differences between threatened and non-threatened species. Some 40% of Critically Endangered, 43% of Endangered, and 55% of Vulnerable species have Areas of Habitat larger than their published ranges, compared with 31% for Near Threatened and Least Concern species. The important finding for conservation is that threatened species are generally more widespread than previously estimated

    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 investigaci贸n (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.
