Species traits and interaction rules shape a species‐rich seed‐dispersal interaction network
Ecology and Evolution, Volume 7, Issue 12, Page 4496-4506, June 2017., 2017 We examine how species traits may affect the rules leading to patterns of interaction among plants and fruit‐eating vertebrates. The structure of the analyzed interaction network was better explained by constraints in resource exploitation in the case of birds and by preferential consumption of fruits with specific traits for mammals.

Radial-arm-maze behavior of the red-footed tortoise (Geochelone carbonaria).
Journal of Comparative Psychology, 2012 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.

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.Abstract The alpha‐taxonomy of continental giant tortoises (Testudinidae, Titanochelon) from the European Neogene is far from settled, which has implications for inferring their phylogenetic relationships. The diagnosis of the type species (Titanochelon bolivari) is dubious because it considered Titanochelon richardi as a junior subjective synonym ...

cDNA‐derived amino‐acid sequence of a land turtle (Geochelone carbonaria) β‐chain hemoglobin [PDF]
IUBMB Life, 1997 AbstractThe cDNA sequence encoding the turtle Geochelone carbonaria β‐chain was determinated. The isolation of hemoglobin mRNA was based on degenerate primers' PCR in combination with 5′‐ and 3′‐RACE protocol. The full length cDNA is 615 bp with the ATG start codon at position 53 and TGA stop codon at position 495; The AATAAA polyadenylation signal is ...

Spatial learning and memory in the tortoise (Geochelone carbonaria)
, 2013 A single tortoise (Geochelone carbonaria) was trained in an eight-arm radial maze, with the apparatus and general procedures modeled on those used to demonstrate spatial learning in rats.

Oxygenation properties of hemoglobin from the turtle Geochelone carbonaria.
Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologica, 1996 The oxygen-binding properties of hemoglobin (Hb) from the adult terrestrial turtle Geochelone carbonaria are described. Turtle hemoglobins have a low intrinsic oxygen affinity and a low sensitivity to an endogenous cofactor (ATP) usually present at high concentrations in the reptile erythrocytes.

Gaze following in the red-footed tortoise (Geochelone carbonaria)
, 2013 Gaze following refers to the ability of an animal to orient its gaze direction to that of another organism. Such a behavior may be adaptive as it alerts the observer to important objects in the environment such as food or predators.

Social learning in a non-social reptile (Geochelone carbonaria)
, 2013 The ability to learn from the actions of another is adaptive, as it is a shortcut for acquiring new information. However, the evolutionary origins of this trait are still unclear. There is evidence that group-living mammals, birds, fishes and insects can
