PAST PROJECTS
Impact of forest eutrophication on plant diversity and animal-plant interactions
In collaboration with Dr. Lucas Garibaldi and the PhD student Margarita Fernández we assessed experimentally the bottom- up effects of forest eutrophication on plant diversity, animal-plant interactions and ecosystem functioning with especial emphasis on pollination, herbivory and nutrient cycling.
Ecological intensification to conserve biodiversity and improve provision of ecosystem services in farmlands
In collaboration with Dr. Lucas Garibaldi, Dr. Georg Andersson, Dr. Fabrice Requier and Dra. Juliana Hipólito we are working in different research lines for assessing how ecological intensification affect biodiversity conservation and the provision of multi-dimensional ecosystem services (environmental, social and economic) in small-holder farms.
Consequences of the Anthropocene defaunation on seed-dispersal mutualisms
In collaboration with Dr.Alfredo Valido, Dr.Pedro Jordano, and Dra. Cristina García we are assessing how downsizing of seed dispersers impacts demographic and genetic issues of mutualistic plants. Our model species (Neochamaelea pulverulenta) is an endemic shrub from Canary Islands, which is dispersed exclusively by medium- to large-sized lizards (Gallotia spp.). Large-bodied species were widespread in the past, but the arrival of aborigines triggered a dramatic process of lizard extinctions on the three islands were N. pulverulenta is present. The magnitude of the process ranged from subtle in Gran Canaria, noticeably in Tenerife, to very marked in La Gomera, defining a defaunation-driven downsizing gradient. As a result, currently only the large-sized lizard species G.stehlini disperse optimally N. puverulenta seeds in Gran Canaria, medium-sized lizards G.galloti disperse them sub-optimally in Tenerife, whereas the dispersal is absent in La Gomera (dispersers become extinct recently).
By using a comparative perspective, the main objetive of the project is understanding how the downsizing of giant lizards affects demography and genetic of Neochamaelea pulverulenta populations. We are applying an integrated study combining island ecology theory, population genetics and movement ecology under a spatially explicit framework.
