Modelos predictivos de la distribución de especies: una revisión de sus limitaciones

Abstract

[ES] En las últimas dos decadas se ha despertado un enorme interés en el modelado de la relación entre las especies y su hábitat, que responde tanto a la demanda de información aplicable a la gestión del territorio y a la conservación como al fundamento básico de la eología en estudiar la distribución y abundancia de los organismos. Sin embargo, los modelos predictivos de distribución de epecies descansan en ciertas presunciones y tienen unas limitaciones que conviene conocer antes de desarrollarlos.En este trabajo se ofrece primero un breve sumario de los tipos de modelado que pueden encontrarse en estudios de ecología, centrandose en los modelos monoespecíficos de distribución, es decir, en aquellos que relacionan las característica del hábiat con la presencia de una especie en particular. Posteriormente, se presenta una síntesis comentada de las limitaciones de carácter biológico y estadístico de los modelos predictivos, analizando en detalle las presunciones en que se sostienen y los problemas metodológicos que dificultan su aplicación. Se concluye que los modelos de distribución de especies están sujetos a numerosos defectos, pero en su desarrollo pueden ofrecer una interesante herramnienta complementaria en la gestión del territorio.

[EN]In the last two decades there has been a growing interest in modelling wildlife-habitat relationships. This is due to the necessity of basic information for land management and conservation, and to the fundamental interest of ecology in studying the distribution and abundance of organisms. However, wildlife-habitat models relay on several asumption, and have some limitations that must be known. This work offer first a brief summary of the type of models that can be found in ecological studies. The focus is on monoespecific models of species distribution, that is, in those that relate habitat characteristics with the presence/absence of a single species, bu the discussion can be extended to other model types, in particular those which deal with several species at a time. Second, a commented synthesis on both statistical and biological limitations of the distribution models is given in detaiñ, with an analysis of the underlying assumptioms and ethodological problems. In conclusion, distribution models have numerous shortcomings but their development may provide a worthy tool for land management
