Body Shape in Skinks: The Relationship between Relative Hind Limb Length and Relative Snout–Vent Length

  title={Body Shape in Skinks: The Relationship between Relative Hind Limb Length and Relative Snout–Vent Length},
  author={Allen E. Greer and Lisa Wadsworth},
Abstract Two basic components of overall shape in scincid lizards were examined in 34 representative species: hind limb length and SVL, both relative to head length. In a bivariate plot of the total available morphological space, only 46% was occupied. Six species that represent the boundaries of the occupied morphological space include a climber on rounded boulders separated by precipitous interstices; a secretive litter-dweller; a bulky, slow moving omnivore; a sand walker/swimmer, and two… 
Body size dimensions in lizard ecological and evolutionary research: exploring the predictive power of mass estimation equations in two liolaemidae radiations
Although more clade-specific equations may reliably predict body mass, more general equations should be used with caution in lizard ecological and evolutionary research, and previous allometric equations proposed to predict mass from length in other ectotherms should be quantitatively assessed before being employed.
Number of Maxillary Teeth in Scincid Lizards: Lineage Characteristics and Ecological Implications
The ratio of the mean number of maxillary teeth to the mean head length is significantly greater in the Eugongylus group of eugongyline skinks than it is in the sphenomorphine skinks.
Body sizes and diversification rates of lizards, snakes, amphisbaenians and the tuatara
Despite a clear modality and skew in the body sizes of lepidosaurs, the relationship between diversification rates and body size is investigated, finding little evidence for faster diversification of modal-sized taxa, perhaps implying that larger-sized clades are relatively young.
A tiny lizard (Lepidosauria, Squamata) from the Lower Cretaceous of Spain
A new squamate taxon is described on the basis of an articulated skeleton from the Early Cretaceous Spanish lagerstatten of Las Hoyas, which differs from other known Mesozoic lizards in combining very small body size with a short rostrum, low maxillary tooth count, a relatively slender and elongated body, and short limbs with large hind feet.
Evolution and ecology of lizard body sizes
Small size seems to promote fast diversification of disparate body plans, and the absence of mammalian predators allows insular lizards to attain larger body sizes by means of release from predation and allows them to evolve into the top predator niche.
Evolution of Body Elongation in Gymnophthalmid Lizards: Relationships with Climate
The present study establishes a connection between morphology and a broader natural component, climate, and introduces new questions about the spatial distribution of morphological variation among squamates.
Musculoskeletal anatomical changes that accompany limb reduction in lizards
The results demonstrate that muscle anatomy in reduced limbs cannot be predicted from bone anatomy alone, meaning that filling the gap between osteological and myological data is an important step toward understanding this recurrent phenomenon in the evolution of tetrapods.
Using 3D‐digital photogrammetry to examine scaling of the body axis in burrowing skinks
The results suggest that there are no substantial head and body shape changes with body size among the sampled species, but further comparative studies with larger sample sizes and functional studies of size and morphology effects on burrowing or above‐ground locomotion are needed.
Structural characteristics of THE Skeleton in Mabuya sp. (Squamata : Scincidae): a comparison with african scincids
To analyze the features of the body plan of Mabuya sp., the structural characteristics of its skeleton are described and compared with other African scincids and are discussed in the context of the
The post hoc measurement as a safe and reliable method to age and size plethodontid salamanders
It is tested the reliability of a noninvasive post hoc method in estimating the snout–vent length (SVL) from photographs showing salamanders’ dorsal view, and the numerous advantages for the use of SVLe in terms of data quality and in reducing the stress caused to wild animals are listed.

The pattern and rate of limb loss are investigated by reviewing data from paleontology and comparative morphology, and theories of the reexpression of limb structures lost in mammalian evolution are considered in the light of facts from paleozoology and genetics.
Tetrapod Limblessness: Evolution and Functional Corollaries
Analysis suggests that elongation for traverse of crevices in a sheltering environment and for the utilization of undulatory locomotion may have provided the initial selective advantage to the system and limb reduction would then have been secondary.
Ecological Shifts in Sympatry: Kalahari Fossorial Lizards (Typhlosaurus)
Strong morphological and dietary evidence support, for T. lineatus females and immatures, the hypothesis that behavioral and morphological character displacement has occurred which reduces dietary overlap with T. gariepensis in sympatry.

ABSTRACT The Terlingua local fauna is a rich assemblage of predominantly terrestrial micro vertebrates from the Upper Cretaceous Aguja Formation of Trans-Pecos Texas. Marine invertebrates (which
Fossil vertebrates from the late Cretaceous Lance formation, eastern Wyoming
The mechanically most effective locomotor specializations are characterized, namely sidewinding, concertina, lateral undulation and rectilinear motion, patterns that exemplify the movements of such derived forms as snakes and amphisbaenians.
