My research focuses on the study of temporary lagoons, which my team has studied in depth in the Doñana area. In this area, we have described the dynamics and physico-chemical characteristics of the lagoons and the communities of aquatic plants, amphibians, reptiles, macroinvertebrates and zooplankton that inhabit them. Comparing the composition of these communities over recent decades has enabled us to highlight the conservation issues currently affecting the Doñana lagoons.
I specialise in amphibians and reptiles, studying aspects relating to their ecology, reproduction and population dynamics, as well as the interactions and the role of different amphibian species during their larval stage. My research into reptiles has focused on chelonians and chameleons, analysing their reproductive ecology and population dynamics, and addressing conservation issues. I also study the impact of non-native species, notably that caused by the Florida box turtle, the red swamp crayfish and the aquatic fern Azolla filiculoides.
In recent years, my research projects have sought to analyse the state of conservation of the temporary lagoons in Doñana, through a multidisciplinary approach that has enabled us to understand how the communities in these environments function and to identify the threats they currently face. This work has highlighted the conservation needs of the Doñana aquifer; to this end, it is essential to reduce groundwater extraction in the areas surrounding the park, both for the irrigation of agricultural land and for the water supply to the nearest residential developments. To disseminate these findings, I have published several chapters on amphibian and reptile species in encyclopaedias (both online and in print), a monograph on the functioning and conservation of the lagoons, and popular science articles on the problems facing the lagoons and the need for their conservation. Furthermore, I have participated, through expert interviews, in national and international documentaries, television programmes and print media, which have served both to highlight the importance and uniqueness of these systems and to raise awareness amongst the public and managing bodies of the urgent need to implement measures that guarantee the conservation of the Doñana lagoons and the species that depend on them.
