Abstract

Wetland ecosystems are important habitats for many waterbird species, including the IUCN nearthreatened Sunda Teal Anas gibberifrons, a species that inhabit wetlands in Indonesia. Muara Angke is one of few remaining wetlands located in Jakarta and has potential as an important habitat for Sunda Teal. This study aims to assess and model suitable habitat for near-threatened Sunda Teal in remaining wetlands in Muara Angke in Jakarta, Indonesia. The study areas include an ecotourism park, the western and eastern parts of the Angke protected forest, and the wildlife reserve. Remote sensing data and geographic information system (GIS) analysis were employed to assess Sunda Teal’s habitat suitability. Some environmental variables negatively influencing habitat suitability for the species include the presence of fishponds and settlements, and represent anthropogenic disturbance. In contrast, variables that may positively influence the species include the occurrence of gastropod and crustacea, both groups being known as food resources, and mangrove cover. The highly and moderately suitable habitats were estimated to form 32.36% and 23.48% of the total wetlands, respectively. In contrast, 12.17% was considered unsuitable for Sunda Teal. The ecotourism park had the most unsuitable habitats. In contrast to the ecotourism park, the protected forest, followed by the wildlife reserve, had more moderately and highly suitable habitats.

Abstract

The Blue tree monitor, Varanus macraei Böhme & Jacobs, 2001 is a tree monitor species favored by reptile keepers. Successful captive breeding was reported from hobbyists and zoos in Europe shortly after its scientific description. Meanwhile, commercial farming to supply international demands has been progressing in Indonesia. However, such successful ex-situ breeding efforts have not yet been documented or published in Indonesia thus far. Therefore, in this, study we describe for the first time the mating behavior and reproduction of a V. macraei couple in an in-country outdoor facility, which is a common husbandry practice for monitor lizard breeders in Indonesia. The male started to approach the female at the beginning of the dry season, in May, with the female showing defensive behavior towards the male, both before mating and after laying eggs, pointing to a seasonal reproductive behavior. Monitor lizards were observed being active during the daytime. Eggs were laid by mid-July 2020. Two of the six eggs laid were revealed to be fertile and hatched after about 23 weeks (5.6 months). The two hatchlings were reared in an indoor enclosure, but only one survived, which showed to be a male.

Abstract

Papilio demoleus L. and P. polytes L. are common butterflies and distribute almost throughout Indonesia. Both species are attractive in butterfly gardens, but may be considered as pests in Citrus plantations. This research aimed to obtain data on their biology, on how the species thrive in captivity, and to assess the alternative host plants. Captive breeding research on these two species was conducted at the butterfly research facility within the period of September 2016 to February 2019, with 482 individuals of P. demoleus and 2,334 individuals of P. polytes reared, of which 292 individuals of P. demoleus and 560 individuals of P. polytes have complete informative data. The average duration of eggs was 3.7 days for P. demoleus on Citrus spp., 3.68 days for P. polytes on Citrus spp., and 3.48 days for P. polytes on Micromelum minutum. The duration of larvae varied between 13–19 days for both species. Prepupal stage lasted for 1 day for all observed individuals. Incidental observation at home during the pandemic COVID-19 added some insights that the pupation happened between 18:00-19:00. The duration of pupae varied between 9–14 days for both species. The total duration of pre-adult stages for both species was between 26–38 days. Adults at the butterfly dome could live up to 19 days for P. demoleus and 39 days for P. polytes. Recognition of alternative host plants is very useful for the improvement of species management in butterfly gardens and in Citrus plantations.

Abstract

The endemic polychaete species Idanthyrsus bihamatus is redescribed based on a new material collected from Bali, Indonesia. All key diagnostic characters of the genus were used to describe the species. Both photo– and SEM micrographs were used to illustrate the species. Additionally, a map was created to show the distribution of the species across the geographic region. The material of the present study is deposited at the Museum Zoologicum Bogoriense in Cibinong, Bogor, and is the first sabellariid collection of the museum.

Abstract

In the article “ASSESSING IN-SITU SEMI-NATURAL BUTTERFLY BREEDING APPROACH OF ORNITHOPTERA CROESUS (PAPILIONIDAE) ON BACAN ISLAND, MALUKU UTARA, INDONESIA” byDjunijanti Peggie, Duncan Neville, Sarino, and SihKahono (Treubia, 48(1): 55–68, June 2021. http://dx.doi.org/10.14203/treubia.v48i1.4129), there was a terrible mistake in using the subspecies name of lydius(Felder & Felder, 1865) instead of croesus Wallace, 1859 throughout the article. Herewith I would like to apologize for the mistake and would like to clarify that: Ornithoptera croesus lydius (Felder & Felder, 1865) distributes in Halmahera, North Maluku Ornithoptera croesus croesus Wallace, 1859 distributes in Bacan, North Maluku Ornithoptera croesustoeantei Parrot & Schmid, 1984 distributes in Morotai For the purpose of avoiding further misleading information, we would replace the pdf of the article with the correct one provided here. Thank you for your understanding and we will make sure that it will not happen again.
