Keragaman Spesies Dan Persebaran Fauna Anura Di Cagar Alam Dan Taman Wisata Alam Telaga Warna

Abstract

Anura includes frogs and toads, playing an important role as ecosystem quality bioindicators, as well as insect population control. Anura is very sensitive to changes in the environment, since its egg stadium. Disruption to its natural habitat, can threaten Anura's survival. This research is done in the Nature reserve area and Telaga Warna Natural Nature Park. Observations using the Visual Encounter Survey (VES) method. Analyses conducted include the calculation of the species diversity index of Shannon-Wienner, the frequency of species meetings, and the density of species. The results of the research gained 11 species of Anura from 5 families, namely Megophryidae, Microhylidae, Ranidae, Dicroglossidae, and Rhacoporidae. The level of diversity of Anura species in the research site is moderate (H ' = 0.152). Density ranged from 0.07 to 0.24 tails/m2, and the highest density is demonstrated by the Rhacophorus margaritifer. The frequency of meetings at a sampling location ranges from 0.01 to 3.6%, with the highest frequency being Rana chalconota. Generally, the quality of the ecosystem of Telaga Warna is good, especially in the area of Gayung Swamp

Rediscovery of Pearly Tree Frog, Nyctixalus margaritifer Boulenger, 1882 (Amphibia: Rhacophoridae) from Mt. Wilis after 135 years

“…It was found on the legume plant in the humid forests around the watershed. 2 Latest N. margaritifer research conducted in Telaga Warna Nature Reserve resulted in a single individual found in a swampy area called "Rawa Gayung", and explained that this species is only known to inhabit undisturbed forests (Setiawan et al, 2019). Our study revealed new microhabitat preferences for N. margaritifer on the coffee tree with a steep slope.…”

“…One specimen was found in Central Java by the Green Community in 2012, which this study shows to be the first report in Central Java. 2 The most recent studies showed a single specimen from Telaga Warna Nature Reserve, West Java with only a single individual observed (Setiawan et al, 2019). A comprehensive study reported that this species can be found only in West Java and Central Java.…”

Diversity, Evenness, and Dominance Index of Amphibians in Lowland Rain Forest: A Case of Anura Ordo in Way Kambas National Park, Indonesia

“…This trend leads to a decrease in the frog population, posing an increasingly significant threat to their survival (Syarif and Maulana 2018). Damage to forests or water pollution causes or even causes the loss of frogs' natural habitat (Setiawan et al 2019). According to Irham (2017), there has been a current degradation in the population of amphibian species; the number of species shortages in amphibians also began to gain in some places caused by the loss or change of habitat, contamination of substances in the waters, changes in environmental conditions as well as damage to ecosystems.…”

Amphibian diversity in the Waterfall of Lubuklinggau City, South Sumatra

“…The high intensity of visits to the two waterfalls can indirectly threaten the presence of amphibians. As we know, amphibians are very sensitive to changes in environmental quality, for example, water pollution, habitat loss, and climate change (Setiawan et al, 2019). While the existence of amphibians is very important for the ecosystem, this is because Amphibians play an important role in the food chain.…”
