Andalusian Envorinment Awards

Colleagues awarded

Juan Calderón Rubiales, former director of the Doñana Biological Reserve (EBD-CSIC) has been awarded in the last edition of the Environmental Awards of the Junta de Andalucía. Juan ("Perote"), retired now, developed his research and professional career during 40 years in Doñana. The jury has highlighted his contributions to the conservation of Doñana, his commitment, his capacity for consensus and his important contributions to knowledge in the defense and improvement of the environment. At the same time, the harbor of Sevilla has been awarded for its management of the sediments from the maintenance dredging of the Guadalquivir river. Using a protocol designed by Miguel Ferrer's team (EBD-CSIC), the creation of suitable habitats for the rest, reproduction and breeding of water birds and other species of interest has been achieved in sediment depots. It is highlighted that this project is an example of how the economic development of a region can be reconciled with the conservation of the environment as part of the emerging philosophy of "Working with nature". CONGRATULATIONS!!

Competition between honeybees y wild pollinators

Competition between honeybees y wild pollinators

During the past decades, managed honeybee stocks have increased globally. Managed honeybees are particularly used within mass-flowering crops and often spill over to adjacent natural habitats after crop blooming. This study uniquely shows the simultaneous impact that honeybee spillover has on wild plant and animal communities in flower-rich woodlands via changes in plant–pollinator network structure that translate into a direct negative effect on the reproductive success of a dominant wild plant. Honeybee spillover leads to a re-assembly of plant–pollinator interactions through increased competition with other pollinator species. Moreover, honeybee preference for the most abundant plant species reduces its seed set, driven by high honeybee visitation rates that prevent pollen tube growth. This study therefore calls for an adequate understanding of the trade-offs between providing pollination services to crops and the effects that managed pollinators might have on wild plants and pollinators. informacion[at]ebd.csic.es: Magrach et al (2018) Honeybee spillover reshuffles pollinator diets and affects plant reproductive success.
