Abstract

Bawean deer (Axis kuhlii) is an endangered Indonesian deer that is quite unique since its habitat is isolated and the species is endemic to the Bawean Island. Data on its biology is very limited. especially those related to antlers growth. Monitoring the antlers growth from the post weaning age (3-4 months) to 22 months old showed that, this process was related to the animals reproductive physiology, starting at the age of six months, when the testes entered the scrotum. and a rapid body growth occured. At the age of 21 months, the animal had its first full hard antlers. The stag had its longest period of hard antlers at least for more than eight months. There seemed to be a close relation between the body growth cycles and theantlers growth. Hair molting lasted for 25-40 days. These results indicated that the period of physiological change in relation to antlers growth and some reproductive activities in the Bawean deer were within the cycle of other temperate and tropical deer species.Key words: Bawean deer, Axis kuhlii, antlers growth, molting

Abstract

Asian grass frog Fejervarya limnocharis is being utilized as pets, for laboratory experiments, for a mixture of traditional medicine and for cuisine. The harvest of F. limnocharis in high volume can threat its population. Biological data such as the age when the specimens are harvested is valuable information to manage the harvesting system in sustainable way. We conducted the skeletochronology technique using paraffin methods and hematoxylin staining from 69 samples (46 males, 21 females, 2 juveniles). The results showed that the age harvested male ranged from 1 to 3 years old, while the female ranged from 2 to 3 years old. The snout-vent length (SVL) of harvested specimens ranges between 39.84−52.37 mm for both sexes. We propose an intervention in the harvesting system by limitation of the size for harvested specimens to at least 46 mm. In this minimum size, individuals of F. limnocharis have reproduced several times and have contributed to the  population in the wild.
