A Study on the Effect of Belly‐Dragging Locomotion on a Robot that Mimics a Heavy Reptile

Advanced Intelligent Systems, Volume 6, Issue 5, May 2024.
Tortoises have high locomotion efficiency while supporting heavyweights through belly dragging. A tortoise‐inspired robot is designed to verify the effect of a tortoise's belly‐dragging posture and gait on energy efficiency. Dynamic simulations and locomotion experiments confirm that adopting a diagonal gait with belly dragging, akin to a tortoise's ...

Where are you from, stranger? The enigmatic biogeography of North African pond turtles (Emys orbicularis) . [PDF]

, 2014
The European pond turtle (Emys orbicularis) is a Nearctic element in the African fauna and thought to have invaded North Africa from the Iberian Peninsula. All North African populations are currently identified with the subspecies E. o. occidentalis.

Skin and skeletal system lesions of european pond turtles (Emys orbicularis) from natural habitats [PDF]

, 2013
Water pollution is known to play an important role in the pathogenesis of plastron, carapace and skin diseases of turtles. In this study, a total of 150 European pond turtles (Emys orbicularis) of different age and both sexes, originating from natural ...

Demographic history and genomic signatures of selection in a widespread vertebrate ectotherm

Molecular Ecology, Volume 33, Issue 5, March 2024.
Abstract Environmental conditions vary greatly across large geographic ranges, and yet certain species inhabit entire continents. In such species, genomic sequencing can inform our understanding of colonization history and the impact of selection on the genome as populations experience diverse local environments.

Body size variation in a lineage of spur-thighed tortoises (Testudo graeca whitei) contrasts with that expected from the species level [PDF]

Ectotherms exhibit varying geographic size patterns shaped by environmental and evolutionary factors. This variability is noticeable within taxonomic groups. For instance, certain testudinids follow Bergmann’s rule (body size increases with latitude) and

Bayesian networks: a probabilistic tool for species distribution models [PDF]

, 2014
Las redes bayesianas son un modelo probabilístico multivariante que permite trabajar con incertidumbre. En general, su aplicación en los modelos de distribución de especies es escasa y centrada en el tratamiento de datos discretos sin aprovechar toda su ...

Biology, Life History Traits and Conservation of the Vulnerable Souss Valley Tortoise in Arid Areas of West Central Morocco [PDF]

, 2018
The Souss Valley tortoise, Testudo graeca soussensis, is endemic to the semi-arid and arid low quality habitats of west central Morocco. Populations of this area are among the best-investigated populations in western Mediterranean.

Efficacy of a Topical Formulation Containing Emodepside and Praziquantel (Profender®, Bayer) against Nematodes in Captive Tortoises [PDF]

, 2017
Gastrointestinal parasites are commonly diagnosed in captive tortoises. In response, fenbendazole has traditionally been used as an anthelmintic, either in single or repeated doses.

Using digital images in the study of fluctuating asymmetry in the spur-thighed tortoise Testudo graeca

TURKISH JOURNAL OF ZOOLOGY, 2013
Fluctuating asymmetry has been proposed as a useful noninvasive tool for detecting the influence of the environment on body development. In the present study, we used digital images to estimate the fluctuating asymmetry of the plastron in an isolated Testudo graeca population in Dobrogea, Romania.
