Abstract

The research was conducted from January 2002 to June 2003 at Pulau Rambut Wildlife Sanctuary Jakarta Bay. The objectives of this research were to explore the breeding strategy of Little Black Cormorant {Phalacrocorax sulcirostris) by analyzing their nest materials. The birds built their nest by using natural and unnatural materials. The shape and texture of nest material were rigid, rope-like and soft. The sources of nest material were trees, forest floor, beach, abandoned nest, aquatic plant living on the bottom of tbe sea, floating material from Java Island and fisherman activities at the sea surrounding Pulau Rambut Wildlife sanctuary.In addition they also collected nest materials by stealing from other nests, nest material carried by other flying individual, and from other individual floating on the sea while seizing the nest material in their beak. All nest materials were carried with their beak.Rigid materials were carried horizontally or diagonally and rope-like material were dorsally or ventrally.

Abstract

The orangutan, a vital component of the rainforest ecosystem, is increasingly threatened by habitat loss and fragmentation. Identifying orangutan nests and feeding trees is an important elements in understanding the habitat's capacity to sustain this species. Using the transect method, this study was conducted on 40 grids out of a total of 623 grids in the Tripa area that are still covered by forest. This study aimed to record the presence of orangutan nests and identify various plant species that serve as food sources for orangutans. The result revealed the discovery of orangutan nests in 7 locations, most of which were categorized as type C (old) and type D (very old). A total of 13 potential orangutan food plant species were found in the Rawa Tripa forest area, consisting of the families Moraceae, Euphorbiaceae, Annonaceae, Myrtaceae, Myristicaceae, Apocynaceae, Piperaceae, Dipterocarpaceae, Urticaceae, and Pandanaceae. This suggest that these areas may have supported a significant orangutan population in the past, but their current activity appears to be declining. The findings underscore the need for conservation efforts, as the continued survival of orangutans is crucial not only for their species but also for the ecological health of the forests they inhabit.

Abstract

Abstract: The Great Argus (Argusianus argus) is a ground-dwelling pheasant species whose reproductive behavior is characterized by the establishment and maintenance of display courts used during courtship. Information on the distribution and habitat characteristics of these display courts remains limited, particularly in Sumatra. This study aimed to assess the distribution and characterize the habitat conditions associated with Great Argus display courts at the Soraya Research Station (SRS), Aceh, Indonesia. Field surveys were conducted from April to July 2024 to locate display courts and evaluate their surrounding habitat characteristics. Vegetation data were collected using 40 sampling plots (20 × 20 m) established around the identified display courts.A total of 10 display courts were recorded within an approximately 500-ha study area. Display courts were located at elevations ranging from 120 to 207 m above sea level and on slopes of 2–19°, indicating a preference for relatively flat to gently sloping terrain. The mean display court perimeter and area were 26.8 m and 58.07 m², respectively. Environmental conditions surrounding the display courts were characterized by a mean air temperature of 27.0°C, soil temperature of 27.3°C, light intensity of 378.4 cd, relative humidity of 76.5%, and soil pH of 6.6. Vegetation analysis revealed a high level of tree species diversity, with a Shannon–Wiener diversity index (H′) of 4.43. The highest Importance Value Index (IVI) values were recorded for Streblus elongatus and Artocarpus sp., indicating their dominance within the vegetation community surrounding several display courts. The occurrence of display courts in areas with high tree diversity and specific topographic conditions suggests that habitat structure may influence display court establishment by Great Argus. These findings provide important ecological information for understanding habitat requirements of the species and may contribute to the development of conservation and habitat management strategies for Great Argus populations in Aceh and other parts of Sumatra. Abstrak: Kuau raja (Argusianus argus) merupakan salah satu spesies burung dari famili Phasianidae yang memiliki perilaku unik berupa pembuatan arena kawin (display court) sebagai tempat untuk menarik pasangan selama musim reproduksi. Penelitian ini bertujuan untuk mengkaji sebaran dan karakteristik arena kawin kuau raja di Stasiun Penelitian Soraya (SPS), Aceh. Penelitian dilaksanakan pada April hingga Juli 2024. Metode yang digunakan meliputi metode jelajah untuk mengidentifikasi dan memetakan sebaran arena kawin serta metode purposive sampling untuk menganalisis vegetasi di sekitar arena kawin. Sebanyak 40 plot pengamatan berukuran 20 × 20 m ditempatkan di sekitar arena kawin yang ditemukan. Hasil penelitian menunjukkan bahwa terdapat 10 arena kawin yang tersebar pada area seluas sekitar 500 ha dengan kisaran ketinggian 120–207 m di atas permukaan laut dan kemiringan lereng 2–19°. Kuau raja cenderung membangun arena kawin pada lokasi dengan topografi datar hingga landai. Rata-rata keliling arena kawin mencapai 26,8 m dengan luas rata-rata 58,07 m². Kondisi lingkungan di sekitar arena kawin ditandai oleh suhu udara rata-rata 27,0°C, suhu tanah 27,3°C, intensitas cahaya 378,4 cd, kelembapan relatif 76,5%, dan pH tanah 6,6. Analisis vegetasi menunjukkan bahwa keanekaragaman jenis pohon di sekitar arena kawin tergolong tinggi, dengan nilai indeks keanekaragaman Shannon–Wiener (H') sebesar 4,43. Jenis pohon yang memiliki Indeks Nilai Penting (INP) tertinggi pada beberapa arena kawin adalah Damli (Streblus elongatus) dan Cempedak Air (Artocarpus sp.). Hasil penelitian menunjukkan bahwa keberadaan arena kawin kuau raja berkaitan erat dengan kondisi habitat, terutama struktur vegetasi dan karakteristik topografi. Temuan ini dapat menjadi dasar ilmiah dalam upaya konservasi dan pengelolaan habitat kuau raja, khususnya di Stasiun Penelitian Soraya, Aceh.

Abstract

Abstract: Fish reproductive condition is widely recognized as a sensitive biological indicator of ecosystem health because reproductive processes are strongly influenced by environmental conditions. This study aims to inventory fish species and analyze the reproductive condition of female fish through gonad and histology studies as indicators of the health of the Rawa Tripa ecosystem. Fish samples were collected at 6 location and then were identified to the species level. Reproductive analysis was performed on female fish by observing the level of gonadal maturity and histological preparations to observe the structure of the oocytes. In addition, water quality parameters such as temperature, pH, and dissolved oxygen were measured in situ to support ecological interpretation. The results of the study obtained 88 fish individuals consisting of 12 families and 23 species. The fish species with the most individuals found during the study were Mystacoleucus marginatus, Osteochilus kappenii, Osteochilus hasseltii, Rasbora lateristriga, with 10 individuals each. Only 5 of the 37 examined female individuals (13.5%) exhibited mature gonads, whereas the remaining 32 individuals (86.5%) were in earlier developmental stages. The histology of female fish gonads was obtained from five species, namely Channa lucius, Oreochromis niloticus, Mystacoleucus marginatus, Osteochilus hasseltii, and Osteochilus kappenii. The Tripa Peat Swamp exhibited acidic water conditions (pH 4–7), with temperatures of 25–30°C and dissolved oxygen concentrations of 3–7 mg/L, which may have contributed to  the low number of species with mature female gonads, suggesting environmental constraint on reproductive development. Abstrak: Kondisi reproduksi ikan secara luas diakui sebagai indikator biologis yang sensitif terhadap kesehatan ekosistem karena proses reproduksi sangat dipengaruhi oleh kondisi lingkungan. Penelitian ini bertujuan untuk menginventarisasi jenis ikan serta menganalisis kondisi reproduksi ikan betina melalui kajian gonad dan histologi sebagai indikator kesehatan ekosistem Rawa Tripa. Pengambilan sampel ikan dilakukan pada 6 titik perairan rawa, kemudian diidentifikasi hingga tingkat spesies. Analisis reproduksi dilakukan pada ikan betina melalui pengamatan tingkat kematangan gonad dan preparat histologi untuk mengamati struktur oosit. Selain itu, parameter kualitas air seperti suhu, pH, dan oksigen terlarut diukur secara in situ untuk mendukung interpretasi ekologis. Hasil penelitian diperoleh sebanyak 88 individu ikan yang terdiri dari 12 famili dan 23 spesies. Spesies ikan dengan individu paling banyak yang ditemukan saat penelitian adalah Mystacoleucus marginatus, Osteochilus kappenii, Osteochilus hasseltii, Rasbora lateristriga, yaitu masing-masing sebanyak 10 individu. Hanya 5 dari 37 individu betina yang diteliti (13,5%) yang menunjukkan gonad yang sudah matang, sedangkan 32 individu lainnya (86,5%) masih berada pada tahap perkembangan yang lebih awal. Histologis gonad betina ikan yang didapatkan berasal dari 5 spesies yaitu, Channa lucius, Oreochromis niloticus, Mystacoleucus marginatus, Osteochilus hasseltii, dan Osteochilus kappenii. Rawa Gambut Tripa menunjukkan kondisi air yang bersifat asam (pH 4–7), dengan suhu 25–30°C dan konsentrasi oksigen terlarut 3–7 mg/L, yang mungkin menjadi salah satu faktor penyebab rendahnya jumlah spesies dengan gonad betina yang matang, sehingga mengindikasikan adanya kendala lingkungan terhadap perkembangan reproduksi.
