| description | Freshwater turtles were surveyed at two sites in Sarawak: Loagan Bunut National Park and Balai Ringin.
Capture results were tested against environmental factors such as lunar phase, weather and seasonality to examine
differences in activity level. Proportionally, soft-shelled turtles were most active during the full moon (29.0%) and
the last quarter lunar phase (29.4%). Hard-shelled turtles were active during the full moon 50.0% of the time. Both
soft-shelled and hard-shelled turtles were more active during overcast periods (53.0% and 66.0%, respectively).
Seasonality did not seem to affect soft-shelled turtle activity, while hard-shelled turtles were active 50.0% of the time
during the dry South-west Monsoon from June to September. |
