Evaluation of locomotor activity in female Chelonoidis chilensis (Testudinidae, Gray 1870) in response to artificial photoperiod and temperature treatments

Amphibia-Reptilia, 2022
Turtles as many other reptiles are capable of orientating their bodies toward the sun. This conduct requires the presence of an internal biological chronometer in the organism that regulates this behavior.

Morphological definition of Eurotestudo (Testudinidae, Chelonii): First part

Annales de Paléontologie, 2006
Abstract This work details the morphological analysis upon which the creation of the testudinid genus Eurotestudo was based. The study is presented in two parts. The present first part includes an introduction to the subject, and the morphological data with illustrations, which formed the basis for the analysis.

Chromosomal relationships of the tortoises (family Testudinidae)

Genetica, 1982
Banded chromosomes of five species of testudinid turtles (Geochelone pardalis, G. elongata, G. elephantopus, Gopherus berlandieri, and G. polyphemus) reveal little variation within either genus, although there are differences in amount and distribution of heterochromatin between Geochelone pardalis and G. elongata.

Prevalence of Tick (Acari: Ixodidae) Parasitism on Pancake Tortoises, Malacochersus tornieri (Testudinidae), Is Lower Inside than Outside Tarangire National Park, Tanzania

Chelonian Conservation and Biology, 2021
. In natural wildlife populations, parasite–host interactions are common ecological phenomena that can be important to community structure. We assessed the prevalence of tick infestation on pancake tortoises, Malacochersus tornieri, with respect to ...

Chondrocranial anatomy of Testudo hermanni (Testudinidae, Testudines) with a comparison to other turtles

Journal of morphology
Using histological cross‐sections, the chondrocranium anatomy was reconstructed for two developmental stages of Hermann's tortoise (Testudo hermanni). The morphology differs from the chondrocrania of most other turtles by a process above the ectochoanal ...

Modeling ecological differentiation in the distribution patterns of two subspecies of the Greek Tortoise, Testudo graeca (Reptilia: Testudinidae) in Iran

Zoology in the Middle East
This study investigates ecological niche differentiation between Testudo graeca zarudnyi and T. g. buxtoni in Iran. Using Species Distribution Modeling (SDM), we analyzed 20 environmental layers derived from bioclimatic and elevation data available ...

A new species of a bony spur-thighed tortoise from the Early Pliocene (MN15) of Jradzor site, Armenia, and the origin of the Testudo graeca (Testudines, Testudinidae) complex

Swiss Journal of Palaeontology
The origin of the Testudo graeca complex has been suggested to be in the Caucasus. Poor fossil records and incomplete preservation of available fossils limit deep-time reconstructions of the paleobiogeographic history of the complex. The present work
