No evidence of contagious yawning in the red-footed tortoise Geochelone carbonaria
Three hypotheses have attempted to explain the phenomenon of contagious yawning. It has been hypothesized that it is a fixed action pattern for which the releasing stimulus is the observation of another yawn, that it is the result of non-conscious mimicry emerging through close links between perception and action or that it is the result of empathy, involving the ability to engage in mental sta...
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 کاملMorphological 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 کاملSpatial learning and memory in the tortoise (Geochelone carbonaria).
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. The tortoise learned to perform reliably above chance, preferentially choosing baited arms, rather than returning to arms previously visited on a trial. Test sessions that examined control by olfactory cues re...
متن کاملSite fidelity and movement of Chelonoidis carbonaria (Spix, 1824) (Testudinidae) in cocoa plantations in southeastern Brazil.
Red-footed Tortoises (Chelonoidis carbonaria Spix, 1824) raised as pets and voluntarily handed over to environmental officers by their owners or apprehended by officers represent a large contingent of animals that overfill triage centres in Brazil. There is no consensus on the fate of these animals, and their numbers continue growing. In this study, we evaluated the movement patterns of C. carb...
