Feeding in Syntopy: Diet of Hydromedusa tectifera and Phrynops hilarii (Chelidae)
Chelonian Conservation and Biology, 2010 Abstract Stomach contents were obtained from 25 Hydromedusa tectifera and 47 Phrynops hilarii that live in syntopy in a pampasic stream in Buenos Aires province, Argentina. Both species are arthropod consumers. Copepods, ostracods, and hemipterans are the preferred items for P. hilarii, and H.

Demography of Acanthochelys spixii (Testudines, Chelidae) in the Brazilian Cerrado
Chelonian Conservation and Biology, 2011Abstract We estimated demographic parameters for Acanthochelys spixii in Parque Nacional de Brasi lia, Distrito Federal, Brazil, based on 4 years of data collection, and also analyzed the effects of sex, temporal variation, and climatic factors on population dynamics. The adult sex ratio did not vary significantly from 1∶1.

The feeding apparatus of Chelus fimbriatus (Pleurodira; Chelidae) – adaptation perfected?
Amphibia-Reptilia, 2010AbstractThe feeding apparatus of the fringed turtle Chelus fimbriatus (Schneider, 1783) was studied to elucidate the feeding mechanics of an aquatic feeding specialist that has never been investigated in detail before, regarding gross morphology. The skull and hyoid apparatus as well as associated musculature were examined by computer tomography and ...

The Etymology of Chelodina Fitzinger, 1826 (Testudines: Chelidae)
Journal of Herpetology, 1996Fitzinger (1826) proposed the new generic name Chelodina for a turtle species previously identified as Testudo longicollis Shaw, 1793 (Goode, 1967), but did not provide an etymology. Agassiz (1844) derived the name from Greek chelys "tortoise" and Greek dine "circular rotation," and emended the spelling to Chelyodina.

Helminth Assemblages of the Turtle Emydura macquarii (Pleurodira: Chelidae) Queensland, Australia
Journal of Parasitology, 2006The helminth fauna of 76 Emydura macquarii from 3 river systems in central and northern Queensland was examined. Eleven species were found, including 2 nematodes, 6 trematodes, 1 aspidogastrean, 1 cestode, and 1 monogenean. Analysis of helminth diversity showed that the Fitzroy and Ross River turtles had communities of comparable diversity, but the ...
