Aproximación a la red de polinización de la flora asociada al cultivo del olivar mediante el estudio palinológico de elementos de restauración para insectos polinizadores ("Bee-Hotels") en olivares.

Abstract

Las actividades humanas y el cambio en el uso de la tierra han reducido la biodiversidad en numerosos ecosistemas provocando una gran crisis de pérdida de biodiversidad a escala planetaria. Esta pérdida de diversidad, se debe, en buena parte, a los efectos de la agricultura. Entre los grupos más amenazados a escala global se encuentran los polinizadores, los cuales son esenciales para el correcto funcionamiento de los ecosistemas terrestres y para asegurar la producción de numerosos cultivos. Nuestro estudio se centra en 9 pares de fincas ubicadas en determinadas localidades de Andalucía dedicadas al cultivo del olivar diferenciándose así, un manejo extensivo y orgánico y un manejo intensivo-convencional, donde examinaremos, mediante el análisis de polen de cajas nido para abejas colocados en estos cultivos, la riqueza y la distribución de frecuencias de interacción de las redes mutualistas plantas-polinizadores en determinadas complejidades de paisaje. Los parámetros analizados han permitido verificar la efectividad ecológica de los cultivos extensivos y orgánicos aumentando la diversidad de interacción, la diversidad de tipos polínicos y la robustez de la red independientemente de la complejidad de paisaje.

Human activities and changes in land use have reduced biodiversity in numerous ecosystems, causing a great crisis of biodiversity loss on a planetary scale. This loss of diversity is due, in good part, to the effects of agriculture. Among the most threatened groups on a global scale are pollinators, which are essential for the correct functioning of terrestrial ecosystems and to ensure the production of numerous crops. Our study focuses on 9 pairs of farms located in certain localities of Andalucia dedicated to the cultivation of olive graves thus differentiating, an extensive and organic management and an intensive-conventional management, where we will examine, through the analysis of pollen from nest boxes of bees placed in these crops, the richness and distribution of interaction frequencies of the plant-pollinator mutualist networks in certain landscape complexities. The analyzed parameters have allowed to verify the ecological effectiveness of the extensive and organic crops increasing the diversity of interaction between species, the diversity of pollen types and the robustness of the network independently of the complexity of the landscape.
