A morphometric characterization of cranial shape in terrestrial carnivorans based on fourier analysis
Pérez-Claros, Juan Antonio
; Martín-Serra, Alberto; Figueirido-Castillo, Francisco Borja; Janis, Christine Marie; Palmqvist-Barrena, Carlos Paul (2013-11-08)
A number of studies have shown that skull morphology reflects the ecological adaptations of terrestrial carnivores as well as their phylogenetic legacy. Here we use Fourier shape analysis for describing the dorsal outline ... -
A three-dimensional analysis of morphological evolution and locomotor performance of the carnivoran forelimb.
Martín-Serra, Alberto; Figueirido-Castillo, Francisco Borja; Palmqvist-Barrena, Carlos Paul (PLOS, 2014)
In this study, three-dimensional landmark-based methods of geometric morphometrics are used for estimating the influence of phylogeny, allometry and locomotor performance on forelimb shape in living and extinct carnivorans ... -
A three-dimensional analysis of the morphological evolution and locomotor behaviour of the carnivoran hind limb
The shape of the appendicular bones in mammals usually reflects adaptations towards different locomotor abilities. However, other aspects such as body size and phylogeny also play an important role in shaping bone design. ... -
Dataset for "Phenotypic integration and modularity drives skull shape divergence in the Arctic fox (Vulpes lagopus) from the Commander Islands"
(The Royal Society, 2019-09-25)La base de datos hace referencia al artículo: Martín-Serra A, Nanova O, Varón-González C, Ortega G, Figueirido B. 2019 Phenotypic integration and modularity drives skull shape divergence in the Arctic fox (Vulpes lagopus) ... -
Demythologizing Arctodus simus, the ‘short-faced’ long-legged and predaceous bear that never was
Figueirido-Castillo, Francisco Borja; Pérez-Claros, Juan Antonio; Torregrosa, Vanessa; Martín-Serra, Alberto; Palmqvist-Barrena, Carlos Paul (Taylor and Francis, 2010)
In this study, we review the previous evidence on the paleobiology of the giant, ‘short-faced’ bear Arctodus simus (Mammalia: Carnivora: Ursidae) and contribute new ecomorphological inferences on the paleobiology of this ... -
Developmental constraints do not influence long-term phenotypic evolution of marsupial forelimbs as revealed by interspecific disparity and integration patterns.
(The University of Chicago Press, 2020-03-03)Marsupials show a smaller range of forelimb ecomorphologies than placental mammals, and it is hypothesized that this results from macroevolutionary constraints imposed by the specialized reproductive biology of marsupials. ... -
Ecomorphological determinations in the absence of living analogs: the predatory behavior of the marsupial lion (Thylacoleo carnifex) as revealed by elbow joint morphology.
(Cambridge University Press, 2016-05-06)Thylacoleo carnifex, or the “pouched lion” (Mammalia: Marsupialia: Diprotodontia: Thylacoleonidae), was a carnivorous marsupial that inhabited Australia during the Pleistocene. Although today all researchers agree that ... -
Evolución de la columna vertebral en pinnípedos actuales y extintos.
(2023)La columna vertebral desempeña un papel muy importante en la locomoción de los mamíferos acuáticos, como los pinnípedos. Sin embargo, el modo de locomoción acuática difiere entre los dos linajes principales de pinnípedos. ... -
Functional anatomy, Ecomorphology and evolution of the carnivoran appendicular skeleton
(Servicio de Publicaciones y Divulgación Científica, 2014)En esta tesis doctoral he utilizado métodos de morfometría comparada para analizar la asociación entre las adaptaciones funcionales del esqueleto apendicular y su evolución morfológica. Por lo tanto, el objetivo principal ... -
Habitat changes and changing predatory habits in North American fossil canids.
(Springer Nature, 2015-08-18)The spread of open grassy habitats and the evolution of long-legged herbivorous mammals with high-crowned cheek teeth have been viewed as an example of coevolution. Previous studies indicate that specialized predatory ... -
In the pursuit of the predatory behavior of borophagines (Mammalia, Carnivora, Canidae): inferences from forelimb morphology.
Martín-Serra, Alberto; Figueirido-Castillo, Francisco Borja; Palmqvist-Barrena, Carlos Paul (Springer Nature, 2016-01-25)
Here, we perform an ecomorphological study on the major bones (humerus, radius, and ulna) of the carnivoran forelimb using three-dimensional geometric morphometrics. More specifically, we test the association between ... -
Integración morfológica entre las extremidades delantera y trasera en carnívoros con dientes de sable: ¿existe alguna evidencia de evolución desacoplada?
Figueirido-Castillo, Francisco Borja; Martín-Serra, Alberto; Palmqvist-Barrena, Carlos Paul (2014-11-12)
The powerfully built forelimb of saber-tooth carnivorans has been traditionally interpreted as part of their prey-killing arsenal, as it is thought to be an adaption to immobilizing their prey before performing a quick and ... -
Investigating the land‑to‑sea transition in carnivorans from the evolution of sacrum morphology in pinnipeds
(Springer, 2023)The form and function of the sacrum are of great relevance to understand the evolution of locomotion in tetrapods because it is a key piece of the vertebrate skeleton. The sacrum connects the caudal and presacral regions ... -
Modular evolution of the carnivoran pelvic girdle: a three-dimensional morphometric approach
Martín-Serra, Alberto; Figueirido-Castillo, Francisco Borja; Serrano-Lozano, Francisco; Palmqvist-Barrena, Carlos Paul (2015-10-28)
The pelvic girdle is a key skeletal structure within the appendicular skeleton in quadrupedal mammals. The pelvis anchors many important muscles and connects the hind limb to the axial skeleton. However, unlike other ... -
Morphological disparity and integration in the vertebral column of pinnipeds (Mammalia, Carnivora).
(2023)The vertebral column has a very important role in locomotion in aquatic mammals, such as pinnipeds. However, the mode of aquatic locomotion differs between pinniped groups. Otariids generate thrust with their forelimbs ... -
Morphological Disparity of the Humerus in Modern Birds
(MDPI, 2020-05)From a functional standpoint, the humerus is a key element in the skeleton of vertebrates as it is the forelimb's bone that connects with the pectoral girdle. In most birds, the humerus receives both the forces exerted by ... -
Non-decoupled morphological evolution of the fore- and hind limb of sabretooth predators.
Martín-Serra, Alberto; Figueirido-Castillo, Francisco Borja; Palmqvist-Barrena, Carlos Paul (Wiley, 2017-07-12)
Specialized organisms are useful for exploring the combined effects of selection of functional traits and developmental constraints on patterns of phenotypic integration. Sabretooth predators are one of the most interesting ... -
Phenotypic integration and modularity drives skull shape divergence in the Arctic fox (Vulpes lagopus) from the Commander Islands
(Royal Society, 2019-09-25)Phenotypic integration and modularity influence morphological disparity and evolvability. However, studies addressing how morphological integration and modularity change for long periods of genetic isolation are scarce. ... -

(2021)Explaining the origin and evolution of a vertebral column with anatomically distinct regions that characterizes the tetrapod bodyplan provides understanding of how metameric structures become repeated and how they acquire ... -
Postcranial elements of small mammals as indicators of locomotion and habitat.
(Peer J, 2020)Many studies have shown a correlation between postcranial anatomy and locomotor behavior in mammals, but the postcrania of small mammals (<5 kg) is often considered to be uninformative of their mode of locomotion due to ...
