Hydrosphere occupancy modeling (ψ) and Akaike (AIC) habitat model selection of urban amphibian in West Java landscape

Amphibians are animal that requires combinations of hydrosphere (riparian vegetation, water body) and vegetation (trees) microhabitats. In urban settings, those microhabitats are scarce and disappearing. One of areas that still have sufficient microhabitats to support amphibian populations is located in an 88.9 Ha urban forests of Universitas Indonesia Campus in West Java. Here, this paper aims to assess and model the several amphibian species occupancy (Ψ) with vegetation covers, riparian vegetation, and water bodies based on Akaike habitat selection (AIC) indices. The studied amphibian species include Bufo melanosticus, Hylarana nicobariensis, Fejervarya limnocharis, and Polypedates leucomystax. For modeling, 7 microhabitat models were developed and tested for amphibian species occupancy with covariates including vegetation cover, riparian vegetation, and water body microhabitats. The Principle Component Analysis (PCA) shows that the occupancies of amphibian were influenced mostly by the presences of water bodies followed by riparian vegetation, and vegetation covers. According to the values of Ψ and AIC, Polypedates leucomystax and Fejervarya limnocharis were species that have high occupancy in riparian vegetation microhabitats with Ψ values of −14.18 and −12.59. Likewise, Hylarana nicobariensis has an equal occupancy in vegetation, riparian vegetation, and water body microhabitats. While Bufo melanosticus shows high occupancy in vegetated microhabitats (Ψ = −14.18) rather than in riparian vegetation and water bodies (Ψ = −8.79). The combinations of riparian vegetation and water bodies show higher occupancy (Ψ = −8.00) rather than Ψ(vegetation cover+water body = −5.64) and Ψ(vegetation cover+ riparian vegetation = −4.36) combinations.

Ordo Anura in Jember University

Some types of Anura have a narrow range of environmental parameters, so they can’t survive in environments where natural conditions change dramatically. Therefore, Anura has the potential to be a good environmental bioindicator. The purpose of this research is to identify the types of Anura found at University of Jember. This research is included in the survey research using direct observation method VES (Visual Encounter Survey). Observations were made of adult members of the Anura Order. Data taken includes species characteristics, abiotic factors such as temperature and humidity, and activity when found. The results showed at Jember University there were 4 species from 3 family members of the Anura order, namely Duttaphrynus melanostictus Schneider, 1799 (Bufonidae), Polypedates leucomystax Gravenhorst, 1829 (Rhacophoridae), Fejervarya limnocharis Gravenhorst, 1829 (Dicroglossidae), and Occidozyga sumatrana Peters, 1877 (Dicroglossidae). The species most commonly found is Duttaphrynus melanostictus which is found in almost every observation location. Environmental factors that support the existence of Anura members in that location are temperature and humidity, and environmental conditions.
