Abstract

The Flores hawk-eagle (Nisaetus floris) is an endangered raptor endemic to the Lesser Sunda region and remains understudied, hindering effective conservation planning. This study investigates the species’ home range, habitat use, and threats at two active nesting sites in Ende District, Flores Island. Home range estimates varied between 8.439 km² (using minimum convex polygon/MCP) and 23.38 km² (using hypothetical-circular home range/HCHR) in Wolojita and from 6.385 km² (MCP) to 23.38 km² (HCHR) in Mbuli. Intensive use areas were relatively small, measuring 0.449 km² in Wolojita and 0.494 km² in Mbuli. Habitat use analysis revealed that in Wolojita, the eagles favored secondary forests, settlements, and shrublands, while in Mbuli, they primarily utilized grasslands and secondary forests, actively avoiding agricultural lands, rice fields, and areas near sulfuric rivers. Secondary forests appear to provide essential resources such as nesting trees and prey availability. However, competition with other raptor species, coupled with anthropogenic threats such as habitat degradation, land-use change, and persecution driven by livestock predation, poses significant risks to the species’ survival. Conservation should focus on preserving secondary forests, promoting sustainable land-use practices, and mitigating human-wildlife conflict to ensure the long-term viability of the population.

Abstract

Wildlife conservation is fundamental to mitigating the extinction due to wildlife trade. Thus, various conservation policies have been used as a reference: IUCN, CITES, and Government Policy P.106 of 2018. This research aims to record Facebook-based wildlife trade, identify the traded wildlife conservation status, and estimate the selling price. Data was taken since the group was formed until 1 July 2023. The results reveal that 107 species belonging to 53 families were recorded in 31 trading groups, comprising 82 species of aves, 17 species of herpetofauna, and eight species of mammals. Among those traded wildlife, based on P.106, 80 species are unprotected, while 27 are protected. Based on the IUCN, most traded wildlife is categorized as LC with 77 species. Some species are categorized as CR with four species, EN with 9, VU with 8, NT with 8, and NE with one species. Referring to CITES, 73 species classified as non-appendices dominate the trading groups, followed by 24 species of Appendix II, 9 of Appendix I, and 1 of Appendix III. The estimated selling price of all traded wildlife is approximately IDR 317,125,000. Governments and other conservation bodies must pay more attention to the growing Facebook-based wildlife trade, especially for protected and endangered species.

Abstract

University campuses are built to carry out the learning process. Therefore, this area has dramatically developed and impacted on the environment and biodiversity. The Nusa Cendana University (Undana) campus area as a habitat for wild animals is included in the built and managed habitat categories. In human-dominated habitats in urban areas such as Undana, it is still possible for animal species to find habitats to find food, shelter, and water sources. This research aims to analyze herpetofauna diversity and update information on preliminary studies of herpetofauna at Nusa Cendana University so that it can be used as primary data for assessing time series. Data was collected using the Visual Encounter Survey combined with the time-constrained search method for three hours from 18.30 to 21.30 WITA at three habitat types (Agricultural, open-area, and built-area habitat). The observation period is divided into two categories: dry and rainy season. Twelve species from eight herpetofauna families, consisting of four amphibians and eight reptiles, were recorded in three habitat types in the Undana campus area. It was recorded that there were six additional herpetofauna species compared to the preliminary study.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kondisi habitat dari jenis burung Myzomela Alor (Myzomela prawiradilagae) dan burung paruh bengkok yang di Pulau Alor yaitu jenis Perkici Timor (Trichoglossus euteles) serta menjelaskan karakteristik jenis pakan dari burung Myzomela Alor (Myzomela prawiradilagae), Perkici Timor (Trichoglossus euteles) dan Kakatua Kecil Jambul Kuning (Cacatua sulphurea parvula). Penelitian ini dilakukan di Pulau Alor terdiri dari dua desa yaitu Desa Tanglapui Timur Kecamatan Alor Timur dan Desa Waisika Kecamatan Alor Timur Laut. Penelitian ini dilaksanakan selama 2 bulan yaitu dari bulan Maret sampai April 2023. Metode Analisis Data menggunakan Analisis Indeks Keanekaragaman Vegetasi yang bertujuan untuk menghitung tingkat keanekaragaman vegetasi yang ada di ke dua lokasi pengamatan dan Analisis Persamaan King yang bertujuan untuk menduga kepadatan populasi burung berdasarkan metode jalur transek. Perkici Timor di lokasi pengamatan menghuni tipe habitat di area lembah sungai, hutan savana dan perkrbunan Kemiri dengan ketinggian 200-300 mdpl sampai 1.114-1.431 mdpl dengan total populasi sebanyak 101,5 ekor. Karakteristik jenis pakan Perkici Timor yaitu nektar dan serbuk sari serta variasi makanan lainnya adalah buah-buahan lunak dan serangga kecil sedangkan Myzomela Alor di lokasi penelitian ditemukan menghuni tipe habitat di sekitaran sumber air (kali/bendungan), semak-semak dan kebun masyarakat dengan ketinggian 35-250 mdpl dengan total populasi sebanyak 50 ekor. Karakteristik jenis pakan dari Myzomela Alor yaitu nektar dari Pohon Jati (Tegtona grandis), Jati Putih (Gmelina arborea), Pohon Kelapa (Cocos nucifera) dan buah Kersen (Muntingia calabura) yang sudah masak.

Abstract

In the Kelimutu National Park area there is a tourist attraction, namely, Lake Kelimutu. The tourist attraction of Lake Kelimutu has a high beauty value, making it always crowded with tourists, both local and foreign. The presence of tourists can be a factor in the level of bird species diversity in the Kelimutu National Park area. This is because birds tend to be sensitive to human presence (Bötsch et al., 2017) so this study aims to determine the diversity of bird species in bird habitats around tourist objects. The method used in collecting data in the field is the path and point method. In data analysis, the method used is the Mackinnon's Species List method. The results of this study indicate that the presence of tourists does not affect the diversity of bird species in habitats around the Lake Kelimutu tourist area.

Abstract

The Insurance Colony Facility (FKA) is an ex-situ conservation center aimed at preparing the Rote snake-necked turtle (Chelodina mccordi), an endemic Indonesian species classified as critically endangered and possibly extinct in the wild (CR-PEW), for reintroduction into its natural habitat. This study employed a morphometric measurement method to evaluate the growth and development of C. mccordi individuals at the Insurance Colony Facility. The study aims to assess the growth of C. mccordi individuals during quarantine and habituation by measuring body weight, carapace dimensions, plastron size, and body circumference. The results indicate that the Rote snake-necked turtles experienced normal growth across most variables. The highest growth rates were recorded in plastron length, which reached 1.4 cm, and in head-to-body length for individuals 2 and 3.
