Abstract

Stingless bees (Apidae: Meliponinae) are distributed in the tropics, and there are more than 600 species worldwide, Forty-six species were recorded in Indonesia. Nest of the species is generally found in tree holes, rocks, house walls, house wooden, bamboo cavities, and soil. Current research explores the species richness, nesting sites and morphometry of stingless bee species in the forest and settlement areas in Banten province, Indonesia. Road- and purposive sampling methods were used to explore the stingless bee species. Thirty-five body characters of each stingless bee species were measured. Results showed four stingless bee species found were Tetragonula laeviceps, Heterotrigona itama, Lepidotrogona terminata, and Tetragonula sp. The dominant species found was L. terminata in the forest, while T. laeviceps in the settlement areas. The nesting sites of stingless bees in the forests were found in the tree cavities of various plant species with tree diameter range 39.3-87.3 cm. In contrast, the nest of T. laeviceps was found in the tree of Swietenia mahagoni, Lansium parasiticum, and bamboo cavities of houses in the settlement areas. The nest entrances of stingless bees varied, i.e., oval-rounded, tubular with varied diameters, and blackish-brown in color. The internal structure of the nest consists of brood cells, pollen cells, and honey cells. Heterotrigona itama has the largest body size (5.52 mm in length), followed by L. terminata (4.99 mm in length) and T. laeviceps (3.86 mm in length). Thirty-three characters of H. itama were larger than L. terminata and T. laeviceps, except for gena width and malar length.

Abstract

Nyamplung (Calophyllum inophyllum), a non-edible producing plant, is a tropical plant traditionally used by local residents as firewood, building material and medicinal plants. The research aimed to study the development of flower and fruit as well as oil content of nyamplung seeds. Two adult trees (P1 and P2) with different provenance were used in experiment. Morphology of flower and fruit, and seed germination were observed from the field, while the microscopic anatomical observations and oil content analysis were carried out in the laboratory. The result showed that a single generative bud generally had 8-15 flowers. The flower was arranged in bunches, with 4 petals, 4 sepals, single pistil and 4 files of anthers surrounded the pistil. In some cases, the flowers had 5 sepals, or 3 sepals and 3 anthers files. Fruits were round, green and turned to harden with brownish color during maturation. Flower bud grown from bud was ready to blossom 27 days after initiation (DAI). There were up to 48.52% flower buds drop at 24 DAI, and they were still increase up to 64.5% flower drop during the whole of flower development. The observation also showed that fruit drop rate of P2 plant was higher than P1. After flower bloom for 3 or 4 days after anthesis, the flowers started to lose their parts. The fruits started to ripe 8-10 week after anthesis (WAA). Seeds from P2 tree had oil content of 51.79%, which was higher than the P1 tree (42.57%).

Abstract

The elephant in Way Kambas National Park (TNWK) is living side by side with the buffalos at the grazing area of TNWK’s buffer village. Considering that, the elephant may compete for food when the buffalo enters the conservation area. Data on the diversity of forage plant species is needed in managing buffalos livestock. This study aimed to identify the forage plants from undigested plant fragments in buffalo feces samples from TNWK’s buffer village. Samples were taken from 10 individuals of buffalo in savanna and palm oil plantation. Analysis of the plant composition was carried out by making microscopic whole mount paradermal sections of undigested plant fragments in the feces. Identification refers to epidermal characteristics that are matched with databases and references. The results showed that there were 21 types of epidermal cells which were dominated from Poaceae characterized by Gramineous stomata. The plants fragments found in almost all of the fecal samples were Hymenachne (Poaceae) and Fimbristylis (Cyperaceae). About 9 of the 21 species of plants consumed by buffalo in the buffer village are also foraged by elephants.
