Inferencia paleoecologica en mamiferos cenozoicos: limitaciones metodologicas

, : Inferencia paleoecologica en mamiferos cenozoicos: limitaciones metodologicas. Coloquios de Paleontologia Volumen Extraordinario 1: 459-474

Environmental, climatic and natural history inference is one of the main aims of Palaeoecology. We have reviewed several autoecological -taxonomic and functional analysis- and sinecological studies -community structure analysis, diversity, cenograms and ecological diversity spectra- generally applied to cenozoic mammals. As a result, theoretical as well as methodological limitations and mistakes are identified, mainly caused by erroneous use of statistical tools and the implicit assumption of non-acceptable statements. Reliability of future studies must be based on solving those problems, specially by a deeper knowledge of recent processes and patterns, the revision of the actualistic principles and the careful use of available methods.
