Abstract

The recent studies were carried out in 1992-1994, and aimed at investigating recent status and distribution of the avifauna of Siberut Island. Ninety-six species were recorded during the observations, of which all endemic subspecies and one endemic species were observed. From all species, 11.5% were very common and 37.5% were common in the island, while 28.1 % of them were uncommon and22.9% were rarely found. Protected and endemic species were amongt the rarely found birds, except the nectar feeding birds which were abundant in the island. Most of these birds might have functioned as either secondary or tertiary consumers, which are vulnerable to habitat deterioration. Habitat conservation may be the best measures to be considered.

Abstract

Being endemic to Borneo, the Earless monitor, Lanthanotus borneensis (Steindachner, 1878) is rarely found in its habitats due to its cryptic behavior. We provide care for confiscated animals in the Reptile House of Museum Zoologicum Bogoriense (MZB) in Cibinong, West Java, Indonesia since 2014. Little is known on its natural prey but from scattered descriptive reports. This study is aimed at documenting the feeding behavior of ten captive Earless monitors and events of predation on frogs. We set up two experiments, one with meat of Rice Field Frog, Fejervarya limnocharis, and the other with live frog of the same species. Our recorded observations ran for four weeks for the frog meat feeding experiment and followed by the frog predation experiment. Our results showed that lizards constantly accepted frog meat. Lizards tended to feed before sunset for a short period of time on the muddy soil surface, although a few individuals inconsistently fed under water. The average body mass for these lizards increased by 4.29 g and average SVL by 0.45 cm. We recorded predation on frogs in three out of ten individuals observed during this study. If F. limnocharis is confirmed to occur in the natural habitats of L. borneensis, it is possible that this frog species is among the natural prey for Earless monitors. Further studies on its natural diets should be conducted to gain in-depth knowledge essential for generating effective captive husbandry for this nationally protected species in Indonesia.

Abstract

Gag island, with 13 species of mammal recorded from a brief survey of only 10 days, has a relatively rich mammal fauna for its area (56 km2). This mammal assemblage was more influenced by faunal elements from nearby Irian Jaya and North Maluku than from elsewhere. More intensive surveys on Gag island will undoubtedly reveal further species of small microchiropteran bats. Habitats on the ultrabasic substrates were richer, more diverse and overall had a higher relative abundance of bats than those on the volcanics. The period of the survey and immediately preceding it was one of intense breeding activity for most, or all, of the bat species and for Rattus sp. The taxonomic status of two still to be identified mammals, a murid rodent Rattus sp. and the Tube - nosed Bat (Nyctimene sp.) on Gag island require further clarification.

Abstract

Systematic of Aganaine moths has been long in dispute since they show both noctuids and arctiids morphological characteristics. Even the relationship among genera within Indonesian Aganaines is still unclear, and their phylogenetic relationships need to be reexamined since the morphological hypothesis proposed previously was not able to show the relationship among them. In order to clarify the phylogenetic relationship among five genera of Indonesian Aganaines, I used sequence of mitochondrial CO I gene (610-bp) to reconstruct their phylogenetic relationship using MP and NJ tree building methods. The results showed that the phylogenetic relationship proposed in this study contradicts the previous hypothesis. The monophyly of subfamily Aganainae has a strong bootstrap support at any tree building methods (88-95%). Neochera was divided into two clades and branched off first and then was followed by Euplocia, Peridrome, Agape, and Asota. The similarity between the previous hypothesis and this study is only on the sister-group relationship between Euplocia and Peridrome and the division of Neochera into two clades. The synapomorphy of Euplocia + Peridrome is a large androconial patch on the forewing upperside at the costal base. This study also showed that all internal nodes gained least supports. It indicates that the relationships among internal nodes proposed here were poorly supported due to the limited number of species and only a short fragment of one mitochondrial gene included in the analysis. Further studies are needed to be done by including more other species, other nuclear genes, and genitalia characters in order to test the validity of the relationships proposed here.Key words: Aganaine, Asota, Agape, Euplocia, Peridrome, Neochera, phylogeny

Abstract

Host specificity has been a major factor in generating the tremendous diversity of phytophagous arthropods. Studies of adaptation to introduced or invasive plant species provide an opportunity to investigate incipient evolutionary changes in host specificity. We investigated the cryptic ability of the Asian tropical herbivorous ladybird beetle Henosepilachna diffinis to feed on the fabaceous weed "centro", Centrosema molle, which was introduced to Southeast Asia about 200 years ago. In laboratory choice tests using this plant and the normal host plant, Solanum torvum, adults preferred S. torvum to centro, but over half the beetles tested ate leaves of both plants. Furthermore, most first-instar larvae accepted centro during a rearing experiment, and a few of them grew to the third-instar stage, though none reached the final (fourth) instar. Henosepilachna diffinis likely acquired this incomplete acceptability of centro without any direct host-grazer interaction with centro, probably before this weed was introduced to Southeast Asia. Our results further suggest that another Henosepilachna species, H. vigintioctopunctata, might similarly have already acquired an incomplete ability to use centro when this beetle encountered it for the first time, and this triggered a subsequent host-range expansion from solanaceous plants to include centro in various parts of Southeast Asia.
