Abstract

ABSTRACTThe aim of this study was to know the vertical distribution of gastropoda at the mangrove Rhizophora apiculata in the Kendari Beach. Method whice isusingin research is transect line. The six transects lines and 20 quadrates 20x20 m for tree, 10x10 m for pole, 5x5 m for boundary pole, ang 2x2 m for seedling. Two samplings of mangrove tree, pole, boundary pole and seedling were chosen each quadrat for observation. The numbers of species and individuals of gastropods were counted in each organ of mangrove samplings (roots, stems, and leaves organs). The parameters of vertical distrubution of gastropods were analyzed including frequency and abundance. The results of this study showed that there exists 8 species of gastropods at the mangrove samplings in Kendari Beach, where seven species found at site I and III, whereas six in found at site II. Species of Littorina scabra showed as the heighest frequency value at all site is 0,75. Therefore, the Littorina scabra are the common snails in this region, bacause they were found at all site in Kendari Beach. The abundance of gastropods in the mangrove sampling was found to be high at roots and has the lowest at leaves. The species of Littorina scabra at all vegetative organs of mangrove samplings in the Kendari Beach and suggesting is widest distribution.Keywords : Gastropods, Abundance, Vertical Distribution, Bay of Kendari.

Abstract

ABSTRACT The aims of this study was to know the litter production of Eha leaves (Castanopsis buruana Miq.) at Nanga-Nanga Papalia protected forest Southeast Sulawesi province. The method that use was litter trap methods with 3 plot establish at study site based on presentage of crown covering. The litter drainage using oven with temperature ± 85ºC to 24 hours. The result of this study showed that litter production of Eha leaves (Castanopsis buruana Miq.) during 4 time of observation showed that the highest average total of litter production on plot I was 55,72 g/m2/weeks, 62,2 g/m2/weeks, 103,3 g/m2/weeks and 104,33 g/m2/weeks. Plot II was 38,10 g/m2/weeks, 41,28 g/m2/weeks, 73,44 g/m2/weeks and 71,73 g/m2/weeks. Plot III 47,47 g/m2/weeks, 49,21 g/m2/weeks, 66,15 g/m2/weeks and 65,19 g/m2/weeks. The mounthly litter production of eha leaves (Castanopsis buruana Miq.) highest on April was 968,29 g/m2/mounth and the lowest on March was 588 g/m2/mounth.Keywords : Litter, Eha (Castanopsis buruana Miq.), Nanga-Nanga Papalia.

Abstract

ABSTRACT The aim of this study was to know the structure and composition of gastropods in seagrass beds in Coastal Waters Lanere Batuawu Village District of South Kabaena. This study was conducted in April to June 2014.The population of this study are all individuals of each type of gastropods were to be found in the study area, the sample of this study is the whole individual types of gastropods contained in the observation plots. The method used in this study was The Line Transect with the placement of plots semi subjective based on the condition of seagrass. The observations were made on 5 transects. The distance between transects were 50 and each transects contains 10 plots.The structure and composition was analyzed quantitatively by determining density, relative density, frequency, relative frequency, Important Value Index, Diversity Index (H), and Evenness Index (E). The result of this study showed that found 27 species of gastropods in whole transects. The Shannon-Wienner estimated index was 1,360 to 1,924 and The Evennes Index was 0,494 to 0,583. Important Value Index highest gastropods were Hebra corticata, Nassarius coronatus and Plicarcularia thersites. Keywords : Gastropods, Structure, Composition, Diversity, Evenness, Seagrass
