XVIII Congreso de la Asociación Ibérica de Limnología

En el recién acabado congreso 2016 del AIL, Laura Serrano de la Universidad de Sevilla organizó una sesión especial muy relevante para nuestros intereses: "Biology, ecology and conservation of large branchiopods". No pudimos asistir en persona al congreso, aunque podemos decir que participamos en el de forma tangencial. 

Nuestros colegas y amigos Jordi Sala & Cie presentaron un póster sobre la distribución de los grandes branquiópodos en la Península Ibérica. Partcipamos en ello con los datos del proyecto "Brankimaki".

Y Juan de García Lomas (SGHN) presentó los nuevos avances sobre la conservación de Linderiella baetica.

This special session will be devoted to large branchiopods, with particular focus on species distribution in the Iberian Peninsula, and conservation issues. Large branchiopods are a group of crustaceans that almost exclusively inhabit temporary ponds, and are often considered a flagship group of invertebrates of these habitats. Species richness is high in the Mediterranean Basin, with 47 species recorded according to the recent review on invertebrates in freshwater wetlands (edited by Batzer & Boix, and soon to be published). The proportion of endemic species reaches 55% as they represent an example of faunal complexes persisting over millennia with many local adaptations. Their vulnerability to predation can explain their isolation to ephemeral habitats and thus, they have been regarded as sentinel species of the impact of exotic species, such as the red-swamp crayfish. There is also an increasing number of publications suggesting that large branchiopods play a pivotal role in the trophic structure and microcrustacean assemblages of ephemeral aquatic habitats. This close relationship between large branchiopods and temporary ponds generates many interesting issues regarding the conservation of these habitats and the species therein. For example, the most critically endangered aquatic animal species in Andalusia is an anostracan (Linderiella baetica n. sp) that has been reported to inhabit a single temporary freshwater pond that is currently unprotected. In Mediterranean regions, temporary ponds are a priority habitat to be preserved though they are defined by particular vegetation communities according to the European Habitats Directive. The scarce knowledge on the ecology and distribution of large branchiopods may have limited the use of this group in protection policy, but this situation may be reversed in view of the increasing number of publications (a fifth of all SCI papers on large branchiopods have been published since 2014), and this special session may contribute to that change.
