However, Red-eared Sliders have more matte or rough shells, yellow marginal scutes; a yellow plastron covered in dark, blotchy markings; and a red ear mark located just behind the eye although this ear mark is not always visible in older specimens Bunnell Unprotected nests at Burnaby Lake are completely depredated often within the first 3 weeks of laying Kilburn, pers.
Populations of generalist predators especially raccoons in these landscapes are often at unnaturally high densities Klemens, ed.
One exception occurred on the Sunshine Coast where turtles overwintered in a reed bed with dense emergent and aquatic vegetation Evelyn and Stiles In Europe, Red-eared Sliders outcompete native turtles for basking sites Cadi and Jolygrow faster, and reproduce better Cadi and Joly The major threats include the loss of aquatic and riparian habitat through residential, agricultural, and industrial development; road expansion and vehicular mortality; collecting for consumptive use and pet trade; and non-native and invasive species Table 2.
Polo-Cavia, N. The plastron has a variation of dark lines with different colors. The gene flow between local populations of the Painted Turtle - Pacific Coast Population is limited in many areas Jensen a; Jensen et al. Turtles of the World.
Your message to the editors. What are the consequences? I am not superstitious. Did you know? In this species, high incubation temperature during egg development reverses genotypic males ZZ into phenotypic females; so females can be ZZ or ZW, but males are always ZZ.
They commonly occur in ponds of urban parks, or other waterbodies of easy human access Bunnell Providing an alternate nesting beach for turtles at Ruby Lake has dropped the mortality rate to turtles per year Kilburn et al.
From data collected over the —17 and —18 nesting seasons, the average surface temperature at nest sites was Proceedings of the Royal Society B. Notes However, in the advent of habitat shifting and alteration, the Painted Turtle - Pacific Coast Population may be able to resist some impacts of climate change through progressive movement northward, providing changes are not too rapid Lesica and Allendorf
