Abstract

Diversity and ecological distributions of amphibians in Berambai Waterfall area, East Kalimantan have never been known. The purposes of this study were to determine the diversity of amphibian species in relation to environmental conditions and the vertical-horizontal distribution. A total of 109 amphibians were captured using methods of the transect and the visual encounter survey for 20 days on two type observation habitats. The results of this study found 18 species from six amphibian families. Based on the number of species, the diversity amphibian index and dominance index have a stable of communities, with the high value of  Shannon-wiener  diversity index (H'),  the evenness  index (E), and the low value of dominance index (D) were 2.26, 0.78, and 0.16, respectively. Horizontal distribution of amphibians in their habitat showed that aquatic amphibian groups were found to be less than 5 m from the river bank, while terrestrial and semi-aquatic amphibians have a distribution of 5?15 m from the river bank. Vertical distribution of Polypedates leucomystax, Polypedates otilophus and Odorrana hosii in vegetation were found from 1.5?2.5 m above ground level, while Ansonia spinulifer, Chalcorana chalconota, Chalcorana raniceps were at a height of 0.5?<1.5 m from ground level. Diversity of amphibian in Berambai Waterfall area related to habitat conditions, while horizontal and vertical distributions are influenced by species, habits and food resources.

Abstract

The research was conducted in April-June 2017, located in the coastal waters of Muara Badak, Muara Badak District, Kutai Kartanegara Regency. This study aims to determine the strucure and community of fish in the coastal waters of Muara Badak and to know the types of fish that have economic value in the coastal waters of Muara Badak. Sampling was carried out using the Stratified Sampling method at 3 stations, which used step-by-step fishing gear. Identification of the types of fish obtained is done at the Laboratory of Animal Ecology and Systematics. Biology Department, FMIPA, Mulawarman University, Samarinda. The results showed that there were total fish catches obtained from the three carry net in the coastal waters of Muara Badak consisting of 28 species 19 families, 5 orders of a total of 407,566 individuals. The type of fish found based on the depth level of the coastline of Muara Badak at a depth of 7 meters found a fish community of 16 species from 4 Orders between l Clupeiformes, Perciformes, Syngnathiformes and Tetraodontiformes, at a depth of 8-10 meters to get as many as 23 species of fish The Order, while at a depth of &lt;10 meters, 19 species of 3 Community Orders were most consumed by the people around the Muara Badak, namely Spratelloides gracilis as many as 340,166 individuals. Of the 2 fish species identified 20 species of economically valuable fish, namely: Alectis indicus, Alepes kleinii, Caesio caerulaurea, Caranx sexfasciatus, Chirocentrus dorab, Lutjanus erythropterus, Lutjanus lutjanus, Megalaspis cordyla, Rastrelliger kanagurta, Sardinella gibbosa, Scomberoides tol, Secutor insiator, Selaroides leptolepis, Siganus canaliculatus, Sphyraena obtusata, Spratelloides gracilis, terapon jarbua, Trichiurus lepturus, Ulua mentalis, Upeneus vittatus.

Abstract

Diversity, potentiality and conservation status of fish fauna in upper Mahakam?s tributaries of east Kalimantan is unknown. The purposes of this study were to analysis species diversity, determine potentiality and conservation status of fish fauna in upper Mahakam?s tributaries, east Kalimantan. Fish sampling with purposive method was conducted in four tributaries, i.e Tepai River, Pahangai River, Danum Parai River, and Meraseh River for one month. Fishes were collected by several gears type. The results of this research showed that the total number of fish caught was 820 individuals; consist of 26 species, 7 families, and 4 orders. The Cyprinidae was the most dominant family found in all tributaries. The Shannon-Wiener diversity index in four tributaries were varied and ranging from 1.749-2.087. The highest fish diversity was recorded at Maraseh River followed by Pahangai River, Danum Parai River, and Tepai River. The low fish diversity was discovered at Tepai River may be due to differences in substrate type, water velocity, and water depth as compared to the Maraseh River, Pahangai River, Danum Parai River. The fish species similarity coefficient between four tributaries ranged from 0.606-0.842 and the highest dissimilarity was found between Tepai River and Danum Parai River. Almost all fishes categorized as edible fish for local consumption. Syncrossus hymenophysa and Gastromyzon lepidogaster have potential as ornamental fish. Regarding IUCN red list status, six fish species were grouped into least concern status, two species as data deficient, one species as near threatened, one species as endangered species and 16 other species were not on the list.

Abstract

Research on diversity and composition of fish at low tide and high tide condition in downstream Kelay River, District Berau, East Kalimantan is not yet know. The purpose of this research was to determine diversity and composition of fish that present at low tide and high tide condition in downstream Kelay River. In research using purposive sampling method and various sizes gill nets used. Results of this research shows that fish were collected at three locations sampling in downstream Kelay River consist of 14 species, 9 families, and 953 individuals. Based on the number of species, diversity Shannon-Wiener index and dominance index has stable of communities, with high value of diversity index (H'=1.975), high evenness index (E=0.749), and low value of dominance index  (D= 0.173). The number of fish species found at low tide were 11 species and at high tide were 12 species. The similarity index of fish species at low tide and high tide condition were 64.3%.
