| kinematics of aquatic and terrestrial prey capture in terrapene carolina, with implications for the evolution of feeding in cryptodire turtles. | studies of aquatic prey capture in vertebrates have demonstrated remarkable convergence in kinematics between diverse vertebrate taxa. when feeding in water, most vertebrates employ large-amplitude hyoid depression to expand the oral cavity and suck in water along with the prey. in contrast, vertebrates feeding on land exhibit little or no hyoid depression. in this study we compared the kinematics of terrestrial and aquatic prey capture within one species of turtle, terrapene carolina, in order ... | 1998 | 9658591 |
| new species of falcaustra (nematoda: kathlaniidae) from heosemys grandis (testudines: emydidae). | falcaustra kinsellai n. sp. from the intestines of the turtle heosemys grandis is described and illustrated. falcaustra kinsellai represents the 30th oriental species assigned to the genus and is distinguished from other species by the distribution pattern of caudal papillae (6 precloacal, 6 adcloacal, 10 postcloacal, and 1 median), length of spicules (427-451 microm), presence of a pseudosucker, and presence of a toothed chamber between vestibule and pharynx. | 2005 | 16419763 |
| the oropharyngeal morphology in the semiaquatic giant asian pond turtle, heosemys grandis, and its evolutionary implications. | the oropharynx as a functional entity plays a fundamental role in feeding. transitions from aquatic to terrestrial lifestyles in vertebrates demanded major changes of the oropharynx for the required adaptations to a different feeding environment. extant turtles evolved terrestrial feeding modes in three families (testudinids, emydids, geoemydids)-independently from other amniotes-and are therefore important model organisms to reconstruct morpho-functional changes behind aquatic-terrestrial trans ... | 2012 | 23029486 |
| evolutionary conservation of transferrin genomic organization and expression characterization in seven freshwater turtles. | serum transferrin (tf), encoding an iron-binding glycoprotein, has been revealed to play important roles in iron transportation and immune response, and it also has been demonstrated to be valuable for phylogenetic analysis in vertebrates. however, the evolutionary conservation, expression profiles and positive selection of transferrin genes among freshwater turtle species remain largely unclear. here, the genomic dna and coding sequences of transferrin genes were cloned and characterized in sev ... | 2018 | 30392910 |
