Abstract

Sea cucumber communities in the wild have different population sizes because there is a high species interaction within the community. Based on the biological organization that is used to express community structure, species diversity is unique to the community level. The objective is to ascertain the structure of sea cucumber communities along the coast of Pasok Village in the Walea Besar District of Central Sulawesi. Data are collected using transect lines, which are divided into three observation stations with ten sampling plots at each. The research method is descriptive-quantitative. The community structure can be known from the domination index (ID), diversity index (H'), and abundance index (J) used to process the data. The results of the study found the diversity index showed the numbers 1.092, 1.056 and 1.089. The dominance of Holothuria scraba species was 0.2 Indv/m2, Holothuria atra 0.14 Indv/m2, and Bohadscia marmorata 0.08 Indv/m2. The highest abundance value belonged to the species Holothuria atra 0.377 Indv/m2 and the lowest to Bohadscia marmorata 0.305 indv/m2. The results showed that the structure of the Holothuroidea community in Pasokan Pantai Village, Walea Besar District, Central Sulawesi, was in the present category.

Abstract

Each habitat has a drastically varied species composition as a result of oil palm plantations filtering out natural forest wildlife, leaving only a limited range of taxa to survive. Among the animal groups with the greatest diversity are insects. The purpose of this study was to determine the diversity of flying insects found in the oil palm plantation area of Wonosari District, Boalemo Regency. The method used in this research is exploration with three observation stations. Station I is adjacent to residential areas, station II is in the oil palm plantation area and station III is adjacent to residents' plantations. Sampling using the trap trap technique using the sweeping net method (insect net) which is commonly used for collecting flying insects. Sample identification in the Biology laboratory, Faculty of Mathematics and Natural Sciences, Gorontalo State University. The data obtained were analyzed descriptively. The results in this study obtained 12 species included in 5 orders and 8 families, namely: Family Nymphalidae (Faunis phaon pan, Amathusia phidippus, Melanitis leda). Pieridae family (Leptosia nina), Hesperiidae family (Platylesches robustus). Family Vespidae (Polistes fuscatus), Family Pyrgomorphidae (Atractomorpha crenulata), Family Acrididae (Trimerotropis pallidipennis, Oxya japonica, Chorthippus albomarginatus), Family Cerambycidae (Glenea albolineata) and Family Libellulidae (Neurothemis terminata) with a total of 24 individuals. Of all the flying insects found, the Diversity Index was 2.362, which indicates that diversity is classified as moderate.
