A survey of prepollex and prehallux variation in anuran limbs
(Wiley Blackwell Publishing, Inc, 2001-02)
This paper reviews skeletal variation of the prepollex and prehallux among anurans and analyses their ontogeny in neotropical species. Morphological diversity is related to the number and features of distal elements. In ...
Morphological Variation in Anuran Limbs: Constraints and Novelties
(Wiley-liss, Div John Wiley & Sons Inc, 2017-09)
Anurans have three primary types of locomotion: walking, jumping, and swimming. Additionally, they may dig, climb, grasp, etc. All adult anurans have four limbs, with four fingers on the hands and five toes on the feet. ...
Hind limb morphometry of terror birds (Aves, Cariamiformes, Phorusrhacidae): Functional implications for substrate preferences and locomotor lifestyle
(Royal Society of Edinburgh, 2017-02)
The hind limbs of birds have long been considered a key feature in the conquest of different environments. However, the high level of morphological diversity encountered complicates the foundation of a good theoretical ...
Postnatal ontogeny of limb proportions and functional indices in the subterranean rodent Ctenomys talarum (Rodentia: Ctenomyidae)
(Wiley-liss, Div John Wiley & Sons Inc, 2014-05)
Burrow construction in the subterranean Ctenomys talarum (Rodentia: Ctenomyidae) primarily occurs by scratch-digging. In this study, we compared the limbs of an ontogenetic series of C. talarum to identify variation in ...
The Suspensory Apparatus and Digital Flexor Muscles of the Llama (Lama glama) 1: The Thoracic Limb
(Sociedad Chilena de Anatomía, 2008)
Multiple Arterial Variations in the Right Upper Limb of a Caucasian Male Cadaver
(Sociedad Chilena de Anatomía, 2010)
Morphology of the limbs in the semi-fossorial desert rodent species of tympanoctomys (Octodontidae, rodentia)
(Pensoft Publishers, 2017-10)
Here, a detailed description of the forelimbs and hindlimbs of all living species of the genus Tympanoctomys are presented. These rodents, highly adapted to desert environments, are semi-fossorial with capacity to move on ...
Are Hemipenial Spines Related to Limb Reduction? A Spiny Discussion Focused on Gymnophthalmid Lizards (Squamata: Gymnophthalmidae)
(Hoboken, 2014)
Calcified spines in the hemipenial surface occur convergently in several gymnophthalmid lizard species and in advanced snakes. Based on the pronounced degrees of limb reduction in these distantly related lineages, such ...
The Adaptive Host Manipulation Hypothesis: Parasites Modify the Behaviour, Morphology, and Physiology of Amphibians
(GB, 2022-09)
Parasites have evolved different strategies to increase their transmission from one host to another. The Adaptive Host Manipulation hypothesis states that parasites induce modifications of host phenotypes that could maximise ...
An unusual pattern of limb morphology in the Tithonian marine turtle Neusticemys neuquina from the Vaca Muerta Formation, Neuquén Basin, Argentina
(Wiley Blackwell Publishing, Inc, 2011-03)
Here, we report an unusual pattern in the manus and pes morphology of the Tithonian marine turtle Neusticemys neuquina. We analyse the forelimbs of two previously known specimens and describe the hind limbs of two previously ...
