| dc.description | The bird species worldwide have faced threats from human or natural factors affecting their habitat. Some of these factors result in forest fragmentation, directly impacting biodiversity. Therefore, estimating bird richness and abundance is necessary to have mathematical tools for assessing environmental impact, designing sustainable projects, and monitoring ecosystem health. This study used Hill indices to evaluate bird richness and abundance in Andean forest fragments located in the municipality of Belmira, Antioquia, Colombia, aiming to identify their potential for birdwatching. The methodology included species sampling using transects as the main method for data collection and analysis. Subsequently, models of accumulation curves, rarefaction curves, and extrapolation were carried out, along with the calculation of birdwatching potential in the study area. Additionally, correlations between landscape variables and Hill index estimates were explored. The results revealed Hill diversity indices with medium to high values in the examined forest fragments, concluding that especially fragment 3 showed a higher potential for birdwatching based on observed trends in accumulation curves. A significant negative correlation was observed between calculated diversity indices and the distance to water bodies, indicating that species richness and abundance increase as the observation point gets closer to water bodies. Furthermore, a potential for birdwatching exceeding 24 points for more than 23 species in the study area was identified, indicating high attractiveness for birdwatching according to the employed methodology. | en-US |
| dc.description | Las especies de aves en el mundo han sido amenazadas por factores humanos o naturales que afectan su hábitat. Algunos de estos factores generan fragmentaciones en los bosques, lo que impacta directamente en su biodiversidad. Por lo tanto, se requiere la estimación de la riqueza y abundancia de aves para disponer de herramientas matemáticas que permitan evaluar el impacto ambiental, diseñar proyectos sostenibles y monitorear la salud de los ecosistemas. En este estudio, se evaluó mediante el uso de los índices de Hill la riqueza y abundancia de aves en fragmentos de bosque Andino ubicados en el municipio de Belmira, Antioquia, Colombia, con el objetivo de identificar su potencial para el aviturismo. La metodología incluyó un muestreo de especies utilizando transectos como método principal para la recolección y análisis de datos. Posteriormente, se llevaron a cabo modelamientos de curvas de acumulación, curvas enrarecidas y extrapolación, junto con el cálculo del potencial de aviturismo en el área de estudio. Además, se exploraron correlaciones entre variables paisajísticas y las estimaciones de los índices de Hill. Los resultados revelaron índices de diversidad de Hill con valores medios y altos en los fragmentos de bosque examinados, concluyendo que especialmente el fragmento 3 mostró un mayor potencial para la observación de aves según las tendencias observadas en las curvas de acumulación. Se observó una correlación negativa significativa entre los índices de diversidad calculados y la distancia a los cuerpos de agua, indicando que la riqueza y abundancia de especies aumentan a medida que el punto de observación se acerca a cuerpos de agua. Además, se identificó un potencial para el aviturismo superior a 24 puntos para más de 23 especies en la zona de estudio, señalando un alto atractivo para la práctica del aviturismo según la metodología empleada. | es-ES |
