Reyes Rojas, Andrea Victoria; Rodríguez Gómez, Guillermo; Martín González, Jesús Ángel; Arsuaga, Juan Luis La reconstrucción paleodemográfica es útil para conocer el desarrollo de las especies extintas. Sin embargo, el registro fósil es parcial y no permite conocer esta información con claridad. Es por esto, que, resulta necesario abordar estos estudios desde métodos alternativos. Uno de ellos es la estimación de perfiles de supervivencia y mortalidad, que permiten reconstruir la estructura de las poblaciones, estimar la capacidad de carga y la disponibilidad de recursos cárnicos en paleoecosistemas.

We developed a paleosynecological model (PSEco) that estimates the production of meat from prey mammals and the densities and biomasses of secondary consumers that could sustain these resources.

This makes interesting to test the conditions immediately before and after the earliest hominin presence. The Late Villafranchian sites of Orce (Guadix-Baza Basin, SE Spain) offer a unique opportunity to analyze the food webs of mammalian paleocommunities in these conditions.

Resource availability and competition with carnivores have been repeatedly proposed to be a main limiting factor for the migration and settlement of Early Pleistocene European populations. The ability of hominins to obtain animal resources from their environment is conditioned by the abundance of prey, their ecological characteristics and the intensity of the competition with other secondary consumers. We present a model which includes the prey-predator interactions in a community and quantifies the available biomass for secondary consumers and the intensity of intraguild competition.
