Abstract

The aim of this study was to identify and describe the Euglenids (Euglenophyceae, Euglenophyta) from the peat waters of Palangka Raya, Central Kalimantan, Indonesia. This study revealed that 8 species of Euglenids were found in the study sites which belong to 3 genera, namely Euglena, Lepocinclis, and Phacus. The Euglenid species identified include Euglena gracilis G.A. Klebs 1883, Euglena mutabilis F. Schmitz 1884, Lepocinclis acus (O.F.Müller) B.Marin & Melkonian 2003, Lepocinclis ovum (Ehrenberg) Lemmermann 1901, Lepocinclis spirogyroides B.Marin & Melkonian 2003, Phacus cordatus (Pochmann) Zakryś & Lukomska 2015, Phacus helikoides Pochmann 1942, and Phacus orbicularis Hübner 1886. The eight Euglenid species found in this study have never been reported before, thus these findings provide additional new data regarding algae diversity in peat waters of Central Kalimantan, Indonesia.

Abstract

Polyculture farming is an agricultural practice of growing several types of crops on the same land.The sustainability of polyculture farming is influenced by the presence of insects, both ecologically beneficial and detrimental. In agricultural ecology, insects have an important role as pollinators, predators, and pests that significantly affect the health of agricultural crops, including in polyculture farms. As an effort for sustainable polyculture management, especially in pest control, an exploratory study with mixed methods was conducted to determine the diversity, distribution, and categories of insects based on their ecological roles. This study was conducted in an agricultural area with a polyculture system in Palangka Raya, Central Kalimantan, Indonesia. A total of 12 insect species were identified from polyculture farms belonging to the orders Coleoptera, Diptera, Hemiptera, Lepidoptera, and Hymenoptera. The diversity of insects found in polyculture farming in this study was categorized into low diversity with a Shannon-Wiener index (H') of 2.186. Hemiptera is known to be the most abundant with 7 species identified. Based on the number of individuals, Componotus japonicus is the most abundant species with 9 individuals. The structure of the insect community based on their ecological role in polyculture farming consisted of 58.33% insect pests, 33.33% predatory insects, and 8.33% pollinating insects.
