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 ... -

Developmental constraints do not influence long-term phenotypic evolution of marsupial forelimbs as revealed by interspecific disparity and integration patterns.
Martín-Serra, Alberto; Benson, Roger B.J. (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. ... -
Evolución de la columna vertebral en pinnípedos actuales y extintos.
Martín-Serra, Alberto; Esteban Núñez, Juan Miguel; Pérez-Ramos, Alejandro; Figueirido-Castillo, Francisco Borja (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. ... -

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.
Figueirido-Castillo, Francisco Borja; Martín-Serra, Alberto; Tseng, Zhijie Jack; Janis, Christine Marie (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
Esteban Núñez, Juan Miguel; Martín-Serra, Alberto; Pérez-Ramos, Alejandro; Rybczynski, Natalia; Pastor, Francisco J.; Figueirido-Castillo, Francisco Borja[et al.] (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).
Martín-Serra, Alberto; Esteban Núñez, Juan Miguel; Pérez-Ramos, Alejandro; Figueirido-Castillo, Francisco Borja (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
Serrano Alarcón, Francisco José; Costa-Pérez, Mireia; Navalón, Guillermo; Martín-Serra, Alberto (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)
