Figures & data
Figure 1. Locations of 38 lakes and seven impoundments where the condition and mortality of western painted turtles (Chrysemys picta bellii) captured as bycatch in modified fyke nets was assessed in northeast South Dakota during 2012–2014. The Prairie Coteau is highlighted in gray, and county boundaries and major rivers are shown.
Figure 2. Proportion of good, poor, and unresponsive western painted turtles (Chrysemys picta bellii) by water temperature (°C). Turtles were captured during fish population assessments using modified fyke nets conducted from 2012 to 2014 in northeast South Dakota.
Figure 3. Proportion of good, poor, and unresponsive western painted turtles (Chrysemys picta bellii) by water temperature (°C), for two time periods (May–June or August–September). Turtles were captured during fish population assessments using modified fyke nets conducted from 2012 to 2014 in northeast South Dakota.
Figure 4. Proportion of good, poor, and unresponsive western painted turtles (Chrysemys picta bellii) across curved carapace length (cm) for each gender (males solid circles, females open circles). Turtles were collected as bycatch during fish population assessments using modified fyke nets conducted from 2012 to 2014 in northeast South Dakota.
Figure 5. Relationship between estimated mortality rate and water temperature (°C; top), water temperature by time period (May–June = solid triangles and August–September = open triangles; middle) and curved carapace length (CCL; cm) for each gender (male = solid circle and female = open circle; bottom). Western painted turtles (Chrysemys picta bellii) were collected as bycatch during fish population assessments using modified fyke nets conducted from 2012 to 2014 in northeast South Dakota.
