Community Structure and Distribution of the Ordo Anura in the Unmul Samarinda botanical Gardens (KRUS), Samarinda City, East Kalimantan
Abstract
Abstract: Unmul Samarinda Botanical Gardens is a forest that
grows naturally, along with population growth and the
development of the city of Samarinda, the Unmul Samarinda
Botanical Gardens (KRUS) is in the middle of the city. The
Unmul Samarinda Botanical Garden is expected to function as
an educational forest that supports science. Since 2001,
Mulawarman University together with the Samarinda City
government have developed a nature recreation/ecotourism
function. In KRUS Forest, apart from high-level vegetation,
shrubs, low-level vegetation and mosses are also found. Wild
animals, birds, reptiles, amphibians and other aquatic animals
also still exist in this area. This study aims to determine the
diversity, evenness and dominance of the order anura. The
method used in collecting data on the diversity of the Anura
order is the Visual Encounter Survey (VES). For sample
identification and data processing, it is carried out at the
Laboratory of Animal Ecology and Systematics, Faculty of
Mathematics and Natural Sciences, Mulawaman University,
Samarinda. Research results show that the composition of the
order Anura in the Unmul Samarinda Botanical Gardens
(KRUS) consists of 18 species, 6 families and 108 individuals.
Species with the highest number of individuals were Limnonectes
paramacrodon and Pulchranapicturata. The index of species
diversity of the order Anura is moderate with a value of 2.26, the
index of evenness is relatively even with a value of 0.79 and the
dominance index indicates that there is no dominant species with
a value of 0.17. There are several factors that pose a threat to the
species of the Anura order in the Educational forest of the
Unmul Samarinda Botanical Gardens (KRUS), such as tourism
activities and coal mining which makes the forest fragmented.
