Staging criteria for embryos of the spiny softshell turtle, Apalone spinifera (Testudines: Trionychidae).
Previous work describing the embryonic stages of turtle development has not included members of the highly derived trionychid turtles. Staging criteria are described for the spiny softshell turtle (Apalone spinifera) to facilitate comparisons between phylogenetically distant taxa of turtles. Embryonic development in A. spinifera is placed in the context of the widely used sequence of Yntema sta...
متن کاملMultiple data sets, high homoplasy, and the phylogeny of softshell turtles (Testudines: Trionychidae).
We present a phylogenetic hypothesis and novel, rank-free classification for all extant species of softshell turtles (Testudines:Trionychidae). Our data set included DNA sequence data from two mitochondrial protein-coding genes and a approximately 1-kb nuclear intron for 23 of 26 recognized species, and 59 previously published morphological characters for a complimentary set of 24 species. The ...
متن کاملStable Cretaceous sex chromosomes enable molecular sexing in softshell turtles (Testudines: Trionychidae)
Turtles demonstrate variability in sex determination ranging from environmental sex determination (ESD) to highly differentiated sex chromosomes. However, the evolutionary dynamics of sex determining systems in this group is not well known. Differentiated ZZ/ZW sex chromosomes were identified in two species of the softshell turtles (Trionychidae) from the subfamily Trionychinae and Z-specific g...
متن کاملApalone ferox – Florida Softshell Turtle
Species Recognition. — The Florida softshell, Apalone ferox, is the largest of the three softshell turtle species found in Florida and has the darkest coloration. It is also the only softshell species found throughout the length of the peninsula. Adults are large to very large (up to 43.6 kg and 73.6 cm carapace length), flat, brown turtles with a cartilaginous shell that is covered by skin rat...
متن کاملResidual yolk energetics and postnatal shell growth in Smooth Softshell Turtles, Apalone mutica.
We examined functions of residual yolk (RY) in hatchling Smooth Softshell Turtles (Apalone mutica). Removal of RY did not affect survival, shell growth, or resting metabolic rates of turtles for 40 d after hatching. Our estimates of metabolic rate suggest that RY can fuel maintenance and activity metabolism for approximately 25 days. A. mutica absorb more than 1g of water in the first 2 weeks o...
