Resumen
[ES] A través de una serie de muestreos se pretende realizar un estudio de la diversidad y la descripción de las
comunidades de arañas (Araneae) presentes en el olivar. Éstos se han llevado a cabo empleando una
metodología concreta en diferentes parcelas situadas en el término municipal de La Guardia de Jaén (Jaén),
entre diciembre de 2022 y mayo de 2023. Dichos olivares son de carácter convencional y debido a los
tratamientos que se emplean para el cuidado y explotación de los mismos, está teniendo lugar una
reducción significativa de la biodiversidad en ellos. Con objeto de conocer en qué medida afecta el período
del año a la diversidad de arañas, este estudio se ha dividido en diferentes fechas de muestreo. Han sido
144 el total de individuos recolectados, pertenecientes a 40 taxones distribuidos en 16 familias diferentes.
El estudio estadístico nos desvela la existencia de una mayor diversidad en una de las tres fechas
seleccionadas, además de existencia de influencia de la época en el número de individuos adultos y
juveniles.
[EN] The aim of a series of samplings is to carry out a study of the diversity and description of the spider communities (Araneae) present in the olive grove. These have been carried out using a specific methodology in different plots located in the municipality of La Guardia de Jaén (Jaén), between December 2022 and May 2023. These olive groves are of a conventional nature and due to the treatments used for their care and exploitation, a significant reduction in biodiversity is taking place in them. In order to find out to what extent the period of the year affects spider diversity, this study has been divided into different sampling dates. A total of 144 individuals were collected, belonging to 40 taxa distributed in 16 different families. The statistical study reveals the existence of a greater diversity on one of the three selected dates, as well as the existence of an influence of the time of year on the number of adult and juvenile individuals.
