| Abstract |
|
The Yellow bellied mud turtle Pelusios castanoides intergularis Bour 1983 on La Digue was investigated within several excursions on the island in December 2004, 2007 and 2008. The main population is located at the Mare Soupape at the west side of the island, however, a second population was found to be present at the water bodies at Grand Anse (east side). On sunny days, activity was restricted to the morning and the late afternoon hours, whereas after rain falls turtles were also active at noon and early afternoon hours. In 2008, a relatively long dry season caused a dramatic decrease in water levels along the island, leading to almost all tributaries of the Mare Soupape drying out and remaining water bodies at Grand Anse were restricted to small areas by the end of the same year. Temporary dry periods will usually not affect freshwater populations on La Digue, however, the drop of water levels seen in the second half of 2008, lasting for longer time periods could result in an additional and permanent habitat loss.
