Abstract
Se realizó un análisis de la diversidad, composición y abundancia de tarántulas, en el área de la Estación biológica José Álvarez Alonso en la Reserva Nacional Allpahuayo Mishana, Loreto-Perú. Se describió la composición de tarántulas que habitan en el área de la Reserva Nacional Allpahuayo Mishana. Para esto se tomaron 9 puntos de muestreo. Cada sitio se muestreo una semana durante la temporada de vaciante en los meses de mayo a julio del año 2023. Se muestreo en el bosque de terraza baja (bosque intervenido), bosque de terraza baja (bosque primario) y varillal seco. Se encontraron 8 especies, teniendo un total de 128 individuos registrados, Megaphobema velvetosoma, Avicularia juruensis, Amazonius burgessi, Cyriocosmus sellatus, Holothele longipes, Avicularia purpurea, Acanthoscurria theraphosoides, Neischnocolus yupanquii. Las tarántulas son buenos indicadores de calidad del bosque ya que una gran cantidad de individuos de ellas puede demostrarnos que en un área no hay muchos depredadores como lagartos y aves, aparte podemos determinar si el área es un lugar inundable de forma permanente o solo por temporadas.
An analysis of the diversity, composition, and abundance of tarantulas was conducted in the area of the José Álvarez Alonso Biological Station in the Allpahuayo Mishana National Reserve, Loreto, Peru. The composition of tarantulas inhabiting the Allpahuayo Mishana National Reserve was described. Nine sampling points were taken. Each site was sampled for one week during the dry season, from May to July 2023. Sampling was carried out in the low-terrace forest (logged forest), low-terrace forest (primary forest), and dry varrial forest. Eight species were found, with a total of 128 recorded individuals: Megaphobema velvetosoma, Avicularia juruensis, Amazonius burgessi, Cyriocosmus sellatus, Holothele longipes, Avicularia purpurea, Acanthoscurria theraphosoides, and Neischnocolus yupanquii. Tarantulas are good indicators of forest quality, as a large number of them can show us that an area lacks predators like lizards and birds. They can also help us determine whether the area is permanently flooded or only seasonally.
