Abstract

Pulau Nusakambangan merupakan sebuah pulau pegunungan kapur dengan gua-gua yang berkembang di dalamnya. Penelitian Arthropoda gua di Nusakambangan dilakukan pada Juni 2003. Dari hasil penelitian di sembilan gua diperoleh 361 spesimen terdiri 62 jenis, 38 famili dari 22 ordo. Dari jenis-jenis tersebut diperoleh 8 jenis yang diduga troglobit dan 51 jenis troglofil dan troglosen sedangkan 4 jenis guanofil.

Abstract

The Study of soil arthropoda diversity in Upper Katingan River area was done in five different forest types i.e. 4 natural forest (With different vegetation) and one industrial tree plantation (HTI). The research site belongs to the PT Dwima Jaya Utama a consession timber in Central Kalimantan. Pitfall traps and soil litter samples were used to collect the arthropods and insect specimen. Twenty pitfall traps were set along 2 transect with 100 m length in each site and were operated forfour day. five soil-litter smaples of two litter were collected from each site. Soil-litter samples were examined in Berlese funnels for two weeks to sort the animals from debris. Identification was done based on the morphological appearce (morphospecies) and some taxon was determined up to order and/of family name. The results show that the most dominated taxon were collembola consit of 103 species from 13 families, and Coleoptera (33 species, 11 families). The most dominated taxon from Class Arachnid was Acarina (11 taxon) and Araneae (7 families). The Kilometer 33 (PUP) area has the highest species richness and abundance, whereas the Industrial Tree Plantation (HTI) has the lowest one of soil Arthropods. Based on the role of Arthropods on the forest floor, the most dominated group was decomposer and followed by predator and phytophagous. The unknown group mostly was consist of juveniles.

Abstract

The development of wild caves into show caves is required an installation of electric lights along the cave passages for illumination and decoration purposes for tourist attraction. The presence of artificial lights can stimulate the growth of photosynthetic organisms such as lampenflora and alter the typical cave ecosystem. The study was aimed to detect the effect of lampenflora on cave-dwelling arthropods community. Four caves were sampled during the study, 2 caves are show caves with the existence of lampenflora and 2 others are wild caves without lampenflora. Arthropods sampling were conducted by hand collecting, pitfall trap, bait trap and berlese extractor. Lampenflora comprises of algae (Phycophyta), moss (Bryophyta) and fern (Pteridophyta) grow mostly around white light lamps. Richness, diversity, and evenness indices of Arthropods are higher in caves with the existence of lampenflora compared to caves without lampeflora. This study clearly shows that the presence of lampenflora can increase Arthropods diversity and suppress dominancy of common Arthropods species in caves, also increasing the relative abundance of predators. This condition will shift the ecosystem equilibrium and lead to cave ecosystem destruction. The results of this study should be a scientific consideration for show cave development and management. Lampenfloras have to be removed from all caves and preventive efforts should be taken to minimize their growth.

Abstract

Collembola in Kalimantan Island is poorly studied even this island has high value of biodiversity especially Collembola. Taxonomically, Collembola in Borneo was studied well by Yosii in Sabah (Malaysia) in the other side, very few report about ecology of Collembola in Kalimantan. This research was aimed to study the ecology of Collembola in five different forest types i.e. 3 natural forest and two Industrial tree plantation (HTI). This study was done in forest on Upper Tabalong River at June 2002. Collembola was collected by using a pitfall traps and soil-litter samples. Each forest type had twenty pitfall traps were set along two transects with 100 in length and operated for four days. Five soil-litter samples were collected in each forest type and modification of Berlese funnel was used to sort out Collembola from soil and litter for two weeks. The results of study show that dominant families in study sites are Paronellidae, Dicyrtomidae and Entomobryidae. These families are surface dwelling Collembola that live on soil surface among the litter. Five different forest types have different Collembolan composition due to different microhabitat, which had different vegetation and diversity. Number of species and individual of Collembola was showed that the highest of Collembola both species and individual was in natural forest (Km 57/Arboretum) and the lowest one was in Industrial tree plantation (HTI 1/Acacia mangium).The richness of collembola was affected by diversity of vegetation in each site and condition of forest floor.
