Obtaining three-dimensional models of limb long bones from small mammals

The use of two-dimensional (2D) pictures to analyse form variation of three-dimensional (3D) objectsentails measurement error, loss of important information and a possible misinterpretation of real shapechanges. Despite the increasing availability of 3D imaging technologies, many geometric morphomet...

Despite the increasing availability of 3D imaging technologies, many geometric morphometricanalyses of 3D objects are often performed on 2D images for several reasons. This issue is particularlyrelevant in the study of postcranial bones from small mammals, as devices precise enough for digitisingtiny objects are the most expensive ones. In this chapter, we describe a photogrammetric protocol toobtain 3D models of limb long bones from small mammals. The procedure is based on obtaining 2Dpictures from different angles using techniques of macro photography. To assess the usefulness of thismethod for geometric morphometric studies, we compare the form of the humerus between fossorial andsemiaquatic water vole species (genus Arvicola).El uso de imágenes bidimensionales (2D) para analizar la variación de forma de objetos tridimensionales (3D) conlleva errores de medición, pérdida de información importante y una posible interpretación errónea de los cambios de forma reales. A pesar de la creciente disponibilidad de tecnologías de imágenes 3D, muchos análisis morfométricos geométricos de objetos 3D a menudo se realizan en imágenes 2D por varias razones. Este tema es particularmente relevante en el estudio de huesos poscraneales de pequeños mamíferos, ya que los dispositivos lo suficientemente precisos para digitalizar objetos diminutos son los más caros. En este capítulo, describimos un protocolo fotogramétrico para obtener modelos 3D de huesos largos de extremidades de pequeños mamíferos. El procedimiento se basa en la obtención de imágenes 2D desde diferentes ángulos mediante técnicas de macrofotografía. Para evaluar la utilidad de este método para estudios morfométricos geométricos, comparamos la forma del húmero entre especies de roedores fosoriales y semiacuáticos (género Arvicola).SERP-Universidad de Barcelona 22018-01-0120182018-01-01Capítol de llibrehttp://purl.org/coar/resource_type/c_3248VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/bookPartapplication/pdfhttps://ddd.uab.cat/record/324337reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengGeneralitat de Catalunya https://doi.org/10.13039/501100002809 2014/SGR-1241open accesshttp://purl.org/coar/access_right/c_abf2Aquest material està protegit per drets d'autor i/o drets afins.
