|
The ecology and biology of the Stripe-necked Terrapin was investigated in Jordan. The main study site was Birket al Ara’is, a natural, spring fed pond in the northwest of Jordan, close to the Golan Heights. Mauremys rivulata was also found in polluted and unpolluted natural and man-made water bodies in the Mediterranean and Irano-turanian regions in northwestern Jordan. A total of 360 turtles were captured, marked and recaptured from February 2001 until April 2002. Dietary studies were undertaken by means of stomach flushing. The Stripe-necked Terrapin was found to be an opportunistic omnivore. A shift in diet from carnivorous in juveniles to herbivorous in adults was noted. It was found that more than half of the sampled population consisted of juveniles, while the ratio of females to males is balanced. Morphometric revealed a straight carapace length ranging from 33 to 200 mm, with females being larger than males. Other measurements taken included weight, carapace width, plastron length, as well as several tail measurements. Body ratios indicated a correlation between morphology and sex. Also, the growth rate of 45 turtles was noted. It was found that juveniles grow at a faster rate than adults, while males have a larger growth rate than females. Threats like habitat alterations, drainage and recent accessibility to the habitat of the Stripe-necked Terrapin are discussed, as well as the possible threat by the introduction of the Red-eared Turtle, Trachemys scripta.
