  • Biomass-diversity responses and spatial dependencies in disturbed tallgrass prairies 
    Sole, Ricard V.; Garcia-Perez Gamarra, Javier (2002-04-21)
    Monotonic, hump-shaped and zero-correlation productivity–diversity relationships have been found to date in many ecosystems. This diversity of responses has puzzled ecologists in their search for general principles on ...
  • Competition and introduction regime shape exotic bird communities in Hawaii 
    Garcia-Perez Gamarra, Javier; Alonso, David; Montoya, Jose M.; Sole, Ricard V. (2005-03-24)
    Complex combinations of historical and local-regional processes determine the assembly of ecological communities. We investigated such processes in the Hawaiian introduced avifauna, comprising 140 years of historical records ...
  • Gap percolation in rainforests 
    Sole, Ricard V.; Bartumeus, Frederic; Garcia-Perez Gamarra, Javier (2005-07-01)
    Rainforests biodiversity is sustained by the three-dimensional structure of their canopy which provides a wide range of physical microenvironments. Given the dynamic nature of the forest, the recognition of stable vertical ...
  • Metapopulations in multifractal landscapes: on the role of spatial aggregation 
    Garcia-Perez Gamarra, Javier (2005-09-07)
    The use of fractals in ecology is currently pervasive over many areas. However, very few studies have linked fractal properties of landscapes to generating ecological mechanisms and dynamics. In this study I show that ...
