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!!

Delivery of crop pollination services is an insufficient argument for wild pollinator conservation

Delivery of crop pollination services is an insufficient argument for wild pollinator conservation

There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it is unclear how much biodiversity is needed to deliver ecosystem services in a cost-effective way. Here we show that, while the contribution of wild bees to crop production is significant, service delivery is restricted to a limited subset of all known bee species. Across crops, years and biogeographical regions, crop-visiting wild bee communities are dominated by a small number of common species, and threatened species are rarely observed on crops. Dominant crop pollinators persist under agricultural expansion and many are easily enhanced by simple conservation measures, suggesting that cost-effective management strategies to promote crop pollination should target a different set of species than management strategies to promote threatened bees. Conserving the biological diversity of bees therefore requires more than just ecosystem-service-based arguments. informacion[at]ebd.csic.es Klejin et al (2015) Delivery of crop pollination services is an insufficient argument for wild pollinator conservation Nat Commun 6 7414 doi:10.1038/ncomms8414
