The Wagner Parsimony using morphological characters: a new method for palaeosynecological studies

The limits and difficulties related to the tools currently in use for palaeosynecological comparisons of faunas or floras of different geological periods are discussed.

La nouvelle méthode de la parsimonie de Wagner appliquée à la paléosynécologie sur la base de caractères morphologiques (méthode WAPUM), est définie et testée à partir des caractères morphologiques de deux groupes d’insectes, les Odonatoptera et les Thripida. Les difficultés liées à la monophylie des groupes taxonomiques utilisés dans les approches plus traditionnelles disparaissent avec la méthode WAPUM. Dans l’approche WAPUM, un caractère est ‘présence/absence d’une espèce portant une structure morphologique’. Les résultats obtenus à partir de la méthode WAPUM minimisent le nombre de changements d’état de caractères. Cet outil permet de tester les scénarios actuellement disponibles pour les changements globaux dans l’évolution de la diversité et de la disparité passée des organismes (changements majeurs ou crises globales de la diversité).Museo de La Plata2010info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArticulohttp://purl.org/coar/resource_type/c_6501info:ar-repo/semantics/articuloapplication/pdf276-292http://sedici.unlp.edu.ar/handle/10915/82469enginfo:eu-repo/semantics/altIdentifier/issn/00379271info:eu-repo/semantics/altIdentifier/doi/10.1080/00379271.2010.10697669info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-sa/4.0/Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)reponame:SEDICI (UNLP)instname:Universidad Nacional de La Platainstacron:UNLP2024-05-08T12:53:34Zoai:sedici.unlp.edu.ar:10915/82469Institucionalhttp://sedici.unlp.edu.ar/Universidad públicaNo correspondehttp://sedici.unlp.edu.ar/oai/snrdalira@sedici.unlp.edu.arArgentinaNo correspondeNo correspondeNo correspondeopendoar:13292024-05-08 12:53:34.684SEDICI (UNLP) - Universidad Nacional de La Platafalse
