Patterns of activity and body temperature of Aldabra giant tortoises in relation to environmental temperature
We studied the temperature relations of wild and zoo Aldabra giant tortoises (Aldabrachelys gigantea) focusing on (1) the relationship between environmental temperature and tortoise activity patterns (n = 8 wild individuals) and (2) on tortoise body temperature fluctuations, including how their core and external body temperatures vary in relation to different environmental temperature ranges (s...
متن کاملGiant tortoises
science. Daytime science is made of the polished, linear, rigorous stories you can read in a journal such as this one, or hear in talks. Night-time science is the messy heap of intuition, despair or elation, association of seemingly unrelated ideas, absolute absence of rigour, that feeds daytime science. To me, night-time science is the creative, exciting bit. The polishing, rigor, and so on, h...
متن کاملRaising giant tortoises
Captive breeding and rearing giant tortoises still represents a challenge and little scientific evidence is available on the requirements of juvenile and adult giant tortoises. Zoo veterinarians must know that developmental diseases are the main risk in the raising process. Respiratory tract disease, endoparasites and biting are other pathologic conditions that have been observed in juvenile gi...
متن کاملTrophic interactions between larger crocodylians and giant tortoises on Aldabra Atoll, Western Indian Ocean, during the Late Pleistocene
Today, the UNESCO World Heritage Site of Aldabra Atoll is home to about 100 000 giant tortoises, Aldabrachelys gigantea, whose fossil record goes back to the Late Pleistocene. New Late Pleistocene fossils (age ca. 90-125 000 years) from the atoll revealed some appendicular bones and numerous shell fragments of giant tortoises and cranial and postcranial elements of crocodylians. Several tortois...
متن کاملPhylogeography and history of giant Galápagos tortoises.
We examined the phylogeography and history of giant Galápagos tortoise populations based on mitochondrial DNA sequence data from 161 individuals from 21 sampling sites representing the 11 currently recognized extant taxa. Molecular clock and geological considerations indicate a founding of the monophyletic Galápagos lineage around 2-3 million years ago, which would allow for all the diversifica...
