Potential effects of highway mortality and habitat fragmentation on a population of painted turtles in Montana E9CBC35D-17E7-4C00-9213-03EFBB0C4692 Year: 2006 Figure B-1. Wire enclosures with aluminum flashing used to test turtle's climbing ability. Figure B-2. Turtles in fencmg enclosure with aluminum flashing. The enclosures were placed at the edge of a pond so that the substrate was always dried mud. Enclosures were placed such that the interior was bare or had little vegetation and no food, water, or shelter was provided. Trials were conducted with wild-caught, naive animals that had no known previous experience with enclosures. Each trial began by randomly assigning 2 turtles to each enclosure and placing the turtles in the center of the enclosure. A total of 177 turtles were used for the trials. Each trial lasted 1 hour during which turtle behavior was noted. Each time a turtle attempted to climb the fencing the highest level it reached was recorded. A turtle was considered to have reached that level if at least 1 claw held onto that rung of wire. If a turtle fell onto its back it was left alone to see if it could right itself. If after 1 minute the turtle was unable to right itself it was turned over by the observer. Trials were run simultaneously in all 8 enclosures and observational data were collected during the entire hour period. Crewmembers were responsible for observations in 2 B-3
