| description | Recently many forests, tropical rain forest, and other plant associations have suffered a process of environmental degradation, attributed to deforestation andfragmentation, with the aim of expanding the agricultural-livestock frontier. These environmental changes have a measurable impact on the fauna communities present, such as birds. A reliable way of documenting the possible anthropogenic effects on ecosystems, is through the analysis of the avian trophic guilds since changes in the structure of the vegetation impacts the different trophic guilds. The main objective of this study was to analyze the variations in richness, abundance, and composition of the bird communities and trophic guilds in three different vegetation cover conditions (rain forest with regeneration SCR, ecotones ECO, and a village POB), in a region of the Lacandon rain forest region, Chiapas, Mexico. Sampling was carried four months of 2020 where six transects of approximately 2 km in length were walked. A total of 6190 individuals from 201 bird species were recorded. The ECO presented the highest richness of birds with 155 species, followed by the SCR (104 species) and finally, the POB (101 species). However, the POB presented the highest abundance of individuals (2661 individuals) with respect to the other two environmental conditions. The greatest similarity of bird communities occurred between the village and the ecotone (53%). The highest number of trophic guilds was also registered in ECO (15). In general, the insectivores were widely represented, particularly in the SCR. On the contrary, granivores were related to open and semi-open spaces, devoid of arboreal vegetation (POB and ECO). Frugivores had greater number of species in the ECO but were more abundant in the POB. Meanwhile, nectarivores were observed more frequently in the POB. Deforestation and fragmentation reduce the physical space of ecosystems and modify the availability of food for birds. This will be reflected in the presence-absence of the different trophic guilds and in the ecological functions they are able to perform. |

Los bosques, selvas y otras asociaciones vegetales han sufrido un proceso de degradación ambiental, atribuido a la deforestación y a la fragmentación con el objetivo de ampliar la frontera agrícola-pecuaria. Estos cambios ambientales no pasan desapercibidos para las comunidades faunísticas presentes, como las aves. Una manera confiable de conocer las posibles afectaciones antropogénicas en los ecosistemas es a través del análisis de los gremios tróficos aviares, ya que los cambios en la estructura de la vegetación condicionan la presencia de diferentes gremios tróficos. El objetivo principal del presente estudio fue analizar las variaciones en la riqueza, abundancia y composición de las comunidades de aves y los gremios tróficos en tres diferentes condiciones de cobertura vegetal (selva con regeneración SCR, ecotonos ECO, y un poblado POB), en una región de la Selva Lacandona, Chiapas, México. El muestreo se realizó durante cuatro meses del 2020 donde se recorrieron seis transectos de aproximadamente 2 km de longitud cada uno. Se registraron en total 6,190 individuos de 201 especies de aves. El ECO presentó la mayor riqueza de aves con 155 especies, seguido por la SCR (104 especies) y finalmente, el POB (101 especies). Sin embargo, el POB presentó la mayor abundancia de individuos (2,661 individuos) con respecto a las otras dos condiciones ambientales. La mayor semejanza de las comunidades avifaunísticas ocurrió entre el poblado y el ecotono (53 %). El mayor número de gremios tróficos también se registró en el ECO (15). En general, los insectívoros tuvieron una buena representatividad, particularmente en la SCR. Por el contrario, los granívoros estuvieron relacionados con los espacios abiertos y semiabiertos, desprovistos de vegetación arbórea (POB y ECO). Los frugívoros tuvieron mayor número de especies en el ECO, pero fueron más abundantes en el POB. Mientras que, los nectarívoros se observaron con mayor frecuencia en el POB. La deforestación y la fragmentación reducen el espacio físico de los ecosistemas y también alteran la disponibilidad de alimento para las aves. Lo anterior, se verá reflejado en la presencia-ausencia de los diferentes gremios tróficos y en las funciones ecológicas que son capaces de realizar.
