A note on the reproduction of Geochelone carbonaria and G. denticulata (Testudines, Testudinidae).
نویسنده
چکیده
On the occasion of having collected three gravid Geochelone carbonaria in the Bolivian Chaco, data are given on oviducal eggs, as well as on five shells of eggs of the same species in the Museum collection. A review of the literature on the reproduction of G. carbonaria and of its sibling G. denticulata is presented, with an elementary statistical treatment of the data on number of clutches per reproductive season, interval between clutches, clutch size, egg shape and volume.

Morphological variations and sexual dimorphism in Chelonoidis carbonaria (Spix, 1824) and Chelonoidis denticulata (Linnaeus, 1766) (Testudinidae).
Chelonoidis Dcarbonaria and C. denticulata are two tortoises which are widely distributed Brazil. Although they occur sympatrically in different areas, C. carbonaria prefers open areas, while C. denticulata chooses forest areas. Significant morphological variations can be observed in these species due to the fact that they occupy a vast and environmentally diverse area. Data on shell shape of c...
متن کاملFunctional behavior of tortoise hemoglobin Geochelone denticulata.
The hemolysate from Geochelone denticulata contains two main hemoglobin components, as shown by ion exchange chromatography and polyacrylamide gel electrophoresis (PAGE). Electrophoresis under dissociating conditions showed three types of globin chains. The apparent molecular mass, as determined by gel filtration on Sephadex G-200, was compatible with tetrameric Hb, which was unable to polymeri...
متن کاملPhylogenetic relationships among the species of the genus Testudo (Testudines: Testudinidae) inferred from mitochondrial 12S rRNA gene sequences.
To test phylogenetic relationships within the genus Testudo (Testudines: Testudinidae), we have sequenced a fragment of the mitochondrial (mt) 12S rRNA gene of 98 tortoise specimens belonging to the genera Testudo, Indotestudo, and Geochelone. Maximum likelihood and neighbor-joining methods identify two main clades of Mediterranean tortoises, one composed of the species Testudo graeca, Testudo ...
متن کاملRadial-arm-maze behavior of the red-footed tortoise (Geochelone carbonaria).
The radial-arm maze is an established method for testing an animal's spatial win-shift behavior. Research on mammals, birds, and fish has shown that the mastery of this task is commonly mediated, to different degrees, by two types of strategy: those based on external cues and those based on response stereotypy. In the present study we trained four red-footed tortoises (Geochelone carbonaria) to...
متن کاملA molecular phylogeny of tortoises (Testudines: Testudinidae) based on mitochondrial and nuclear genes.
Although tortoises of the family Testudinidae represent a familiar and widely distributed group of turtles, their phylogenetic relationships have remained contentious. In this study, we included 32 testudinid species (all genera and subgenera, and all species of Geochelone, representing 65% of the total familial species diversity), and both mitochondrial (12S rRNA, 16S rRNA, and cytb) and nucle...
