Functional 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 کاملNo 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 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 کاملA note on the reproduction of Geochelone carbonaria and G. denticulata (Testudines, Testudinidae).
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...
