Universidad de Zaragoza (orcid)0000-0002-0041-0507 Informatic application to characterise and identify small mammal species: Arvicolinae (Cricetidae, Rodentia, Mammalia) 2024 Access copy available to the general public Unrestricted The classification of rodent species can be challenging due to high morphological similarities observed among them. This problem is further increased in palaeontological systematics, where classification is traditionally based on the molar morphology. The subfamily Arvicolinae (Rodentia, Mammalia) is one of these rodent groups, whose classification being important for biostratigraphic and climatic studies of the Quaternary period is challenging. We present an application developed using the MatLab informatic algorithm, designed to classify the Arvicolinae species using Geometric Morphometrics (GMM) analyses of the first lower molar. Moreover, the application includes an option to automatically obtain the linear measurements that are commonly used for the identification of these species. This method shows a high degree of accuracy in the species classification, which is expected to increase as the reference database is further developed. This application can serve as an alternative tool for the classification of specimens with unclear morphologies. It can also be used to reduce the time required to manually obtain the linear indices necessary for their classification. info:eu-repo/grantAgreement/ES/MCIU/FPU20-02031 info:eu-repo/grantAgreement/ES/MSC/CT18-22 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.3 2024 EVOLUTIONARY BIOLOGY 25 / 53 = 0.472 2024 Q2 T2 ECOLOGY 95 / 200 = 0.475 2024 Q2 T2 0.858 2024 Ecology 2024 Q1 Nature and Landscape Conservation 2024 Q1 Ecology, Evolution, Behavior and Systematics 2024 Q1 4.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Angel-Beamonte, E.
