Abstract

Brahminy kite (Haliastur indus) is one of bird of prey species that occupy position as top predator. Many brahminy kite was captured and was kept as pet which caused those birds lose their ability to hunt as a result of being caged for too long and for not to be trained to hunt. In Bali Wildlife Rescue Centre, the confiscated brahminy kite showed begging behavior in which the birds “whine” every time a human approach. This kind of behaviour affect their readiness to be released in the wild. The purpose of this study was to determine the daily activity and the frequency of begging behaviour of confiscated brahminy kite in Bali Wildlife Rescue Centre. This study was conducted in January 2020. This study found that the brahminy kite at the Bali Wildlife Rescue Centre spent the most of their time for perching. The second highest activity was preening, whereas the least activities were feeding and moving. The highest percentage to beg in brahminy kite was recorded in the morning, whereas the lowest percentage was in the midday. The results of this study indicate that the confiscated brahminy kite at the Bali Wildlife Rescue Centre still needs more time to be rehabilitated prior released ack into the wild.

Abstract

Ring-tailed lemurs (Lemur catta) is a primate that live in Madagascar. Poor habitat quality, limited land area, severe forest fragmentation causes a decrease in the availability of food sources for ring-tailed lemurs in nature so that the ring-tailed lemur population is increasingly threatened. Conservation effort was carried out on ring-tailed lemurs (Lemur catta) outside their natural habitat. One of the conservation institutions in Bali is the Bali Zoo. This study aims to observe the daily behavior and eating preferences of ring tailed lemur (Lemur catta) at Bali Zoo. This research was conducted on seven ring-tailed lemur at Bali Zoo in January-February 2022 and was carried out at 08.00 am – 04.00 pm. The observation method used was the focal animal sampling and the recording was carried out by the instantaneous recording method with an interval of 30 seconds for 30 minutes. The data obtained were analyzed by using Microsoft excel to calculate the daily behavior formulas, and later was described in a comparative descriptive way. The most frequent behavior were resting (resting) 40.97%. The most preferred food for ring-tailed lemur was grapes Vitis vinifera (16.77%). This research provides data and information from the study species in order to help to improve the management of ex-situ conservation.

Abstract

Coral reefs are one of the ecosystems that have an important role for humans. Indonesia is a country that has the largest coral reef ecosystem in the world, however, the condition of coral reef cover that is declared to be poor is relatively not small. Nusa Dua is one of Indonesia’s coast chosen for coral rehabilitation. Coral transplantation and its maintenance have been carried out for seven years by the Nusa Dua Reef Foundation (NDRF) at the coral garden, that located in Nusa Dua. This study was conducted to determine the effect of coral garden on recruitment in the surrounding waters by observing the coral recruitment in the area around the NDRF’s coral garden. Coral recruitment was determined by observing the species of recruit and its density. Recruit colony were determined by using the Underwater photo transect Method (UPT). The study resulted that the overall recruit coral density was 0.65 colonies/m2 which was classified as low. The study found 25 colonies of natural coral recruits from seven genus and six families. The recruit species found were Goniastrea sp., Pocillopora damicornis, Porites sp., Stylophora sp.1, Stylophora sp.2, Galaxea fascicularis, Montipora digitate, Psammocora sp. The species most commonly found was Pocillopora damicornis.
