This study aims to analyze the threat of edge effects on endemic animal populations due to the presence of causeways in the TNGHS corridor habitat. Indicators of the occurrence of edge effects are characterized by the further distance of wildlife populations from sources of disturbance such as noise, light, and frequency of human activity mechanisms. Belt transect research method for population study and distribution of Javan Gibbon and Surili. Intensive Point Account (IPA) to measure the diversity index of bird species and Javan eagles. Encounter Rate is used for animal distribution studies. Results On the observation transect made along 3 km, the population density of Javan Gibbons was obtained 0.114 ind/ha, Surili 0.024 indv/ha, and Monkey 0.028 indv/ha. Bird species diversity index in 3 habitat patches each Purasari H'= 2.78 with 38 species; Garehong with 27 species, and Corridor H'= 3,087 with 27 species. The similarity of species is that there are only 7 species of birds found in the 3 habitats of the patch. As a result of primate population density and burng species similarity, it can be concluded that the cross-corridor access road area has experienced an edge effect and tends to be a bottle-neck area for the distribution of animals, especially primates.

“…Kelimpahan dan keanekaragaman vegetasi yang tinggi berpengaruh positif terhadap kehadiran burung (Xu et al, 2022;Sulaiman et al, 2013). Wilayah lembah serta lahan dengan kemiringan sedang memiliki keanekaragaman lebih rendah (Süel et al, 2021). Keanekaragaman burung juga cenderung lebih tinggi pada lingkungan sosial masyarakat dengan ekonomi tinggi dibandingkan dengan ekonomi rendah (Sultana et al, 2022;Leong et al, 2018).…”

Belitung Island is a satellite island of the mainland of Sumatra Island. So far, bird research has been very rare and there have been almost no recent publications, so research on birds on Belitung Island is needed. The research was conducted during February-April 2020 in seven habitat types in 18 locations. Data were taken using the IPA (Index Point of Abundance) method with observation times between 05.30-09.00 am and 03.00-06.00 pm. Qualitative analysis was carried out on the bird status, while quantitative analysis was carried out using: 1) chi-square for bird species richness; 2) Shannon-Wiener diversity index (H'); 3) evenness index (E); and 4) bird community similarity index (IS). There were 111 bird species from 40 families and 13 orders. The birds found significantly different between habitat types for the number of species (χ²count = 23.73; df = 6; P < 0.05) and the number of individuals (χ²count = 361.65; df = 6; P < 0.05). The number of bird species found ranged from 14 species (lake habitat) to 50 bird species (coastal habitat). One bird species can be found in all habitat types, namely Cinnyris jugularis. Nine species of shorebirds were found. The bird diversity index (H') was obtained at 3.83 which is included in the high category and the bird evenness index (E) was obtained at 0.81 which is included in the high category and means the community is stable. The community similarity index (IS) values between habitat types ranged from 0.10-0.33.

Aim of study: The study aimed to assess the impact of urban woodlands on bird species diversity and abundance in the Anatolian side of Istanbul, focusing on species typically absent from urban centers but found within urban environments. The findings are intended to contribute to the development of future conservation and habitat management strategies. Area of study: The study was conducted in five areas in Üsküdar and Beykoz, including an urban center, three urban woodlands (Fethipaşa, Hidiv, and Beykoz Abrahampaşa) and a natural area in Istanbul's northern region. Material and methods: Data on bird species and their abundances were collected and tabulated through 900 point counts from April 2022 to March 2023. The data was analyzed using abundance values, species richness and diversity, identifying distribution and evenness through rank abundance distribution and curves. Similarity analysis was performed using the clustering method and species composition was compared using a Venn diagram. Main results: Seventy-two bird species were identified across the study areas. A decrease in urbanization density enhances bird species richness, diversity and evenness, with the natural area recording the highest values. Urban woodlands harbor species absent from more urbanized locations. Distinctions in species distribution and bird diversity between the areas were revealed. Research highlights: Urban woodlands are crucial areas for wildlife in metropolises, providing significance from both ecological and sociocultural perspectives. Although they may not match natural areas in species diversity, these woodlands significantly contribute to bird diversity within the urban environments. Further research is needed to explore the unique characteristics of each woodland and their contributions to urban ecosystems.
