Introduction
I am broadly interested in how biodiversity and ecosystem services are shaped through the spatial dimension. My research is focused on the study of frugivorous bird – seed dispersal interactions and its important implications under global change.

Article
Full-text available
Mining activities produce deeply denudated areas that must be restored towards functional and self-sustainable ecosystems. This includes making up new land morphology with efficient drainage network and acceptable soil, and promoting plant succession and the incorporation of different faunal groups; which finally should facilitate the biotic and ab...
Article
Full-text available
Knowledge about species occurrence is essential in terms of biogeographical and conservation research. Species distribution models provide basic information so as to predict vulnerability to local or global extinction or design nature preservation policies. GIS technologies and MaxEnt application have demonstrated respectively efficacy in terms of...
Article
Full-text available
Yellow-legged Larus michahellis, Audouin's Ichthyaetus audouinii and Black-headed Gulls Chro-icocephalus ridibundus are common species in the western Mediterranean where they coincide spatially and temporally. Competition for food resources leads to agonistic interactions, which we predict will have a hierarchical structure following Lanchester's l...
Article
Full-text available
The coexistence of similar species is determined by resource partitioning, while the exploitation of the same resource could lead to competitive exclusion scenarios. The breeding distribution of birds like the Black Wheatear Oenanthe leucura, the Black-eared Wheatear Oenanthe hispanica, and the Blue Rock Thrush Monticola solitarius overlaps in open...
Article
Full-text available
Knowledge of the population status, requirements and spatial distribution of wild species is essential when taking management decisions and undertaking appropriate conservation efforts. A census of much of El Garraf Park, combined with the use of Maxent and GIS technologies, allowed us to generate distribution models for some of this protected a...
Poster
Full-text available
Recovery and subsequent re-use of clean soil left over from excavation works aims to make use of these natural resources in new filling work and related projects requiring earth. GRC fosters landscape and environmental restoration of quarries and other degraded sites, and the improvement of agricultural land. These measures seek to make re-use of s...
Article
Full-text available
Invasive species are one of the most serious anthropic disturbances threatening the preservation of our ecosystems. One such example are plant invasions, especially those linked to the ornamental plant and gardening industries. Trophic interactions between the seeds of alloch-thonous plants and native frugivorous species are of special interest as...
Article
Full-text available
Present paper consists of an exhaustive compilation of most important trophic interactions between bird species that consume differ-ent flora species in restored quarries. A field study is carried out where trophic interactions of a not previously described importance are demonstrated, particularly if we consider its detection in restored environme...
Article
Full-text available
Present paper consists in an exhaustive Queen Crown (Saxifraga catalaunica) census occupying the Natural Park of Montserrat Mountain, allowing to obtain a great perspective of species’ demographic situation within mentioned nature preserved area. Distribution range and altitude limits are studied. Orientation preferences are also considered in the...
