"Anoa merupakan satwa endemik Sulawesi yang terancam punah karena perburuan liar dan kehilangan habitat. Informasi terkait manajemen reproduksi anoa masih terbatas, sehingga upaya konservasi menjadi terhambat. Penelitian terkait manajemen reproduksi perlu dilakukan untuk mengoptimalkan pengembangbiakan anoa. Penelitian ini bertujuan untuk mengetahui faktor pendukung keberhasilan kebuntingan anoa (Bubalus depressicornis C.H. Smith, 1827) melalui kawin alami serta mendeteksi kebuntingan anoa (Bubalus depressicornis C.H. Smith, 1827) melalui perubahan perilaku dan morfologi, pengukuran profil biokimia urine, dan gambaran ultrasonografi transabdominal. Penelitian dilakukan di Anoa Breeding Centre Manado (ABC), Sulawesi Utara. Pengambilan data penelitian dilakukan pada Juli–Oktober 2017 untuk mengetahui siklus estrus, waktu optimal kawin, dan perilaku kawin anoa, pada Maret–Mei 2019 untuk melakukan verifikasi keberhasilan perkawinan alami anoa selama periode April 2016– Mei 2019, dan Januari–Mei 2019 untuk pengukuran profil biokimia urine. Penelitian menggunakan 2 ekor anoa jantan dan 4 ekor anoa. Faktor pendukung kebuntingan dianalisis menggunakan analisis jalur dengan bantuan perangkat lunak SmartPLS dan analisis diskriminan. Data perubahan perilaku dan morfologi dianalisis menggunakan Principal Component Analysis (PCA). Data profil biokimia urine dianalisis menggunakan uji T. Data USG transabdominal dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa terdapat variasi panjang dan lama estrus di antara individu anoa. Panjang siklus estrus anoa berkisar antara 14–24 hari dengan lama estrus 2–4 hari. Berdasarkan hasil SmartPLS diketahui bahwa faktor eksternal (manajemen dan iklim) dan faktor internal (individu jantan dan individu betina) tidak menunjukkan adanya pengaruh nyata terhadap kebuntingan. Berdasarkan analisis Principal Component Analysis (PCA) diketahui bahwa karakteristik utama perubahan perilaku dan morfologi yang menjadi penanda kebuntingan yaitu puting membengkak, ambing susu membengkak, rambut mengilap, bentuk abdomen membesar dan turun, dan frekuensi makan yang meningkat. Peningkatan nilai kadar glukosa dan total protein di dalam urine anoa yang sedang bunting terjadi secara nyata yang nyata USG transabdominal tidak mampu menunjukkan kenampakan vesikel embrionik sebagai tanda awal kebuntingan. USG transabdominal menunjukkan dengan jelas gambaran organ tubuh janin yaitu tulang dada, tulang belakang, kepala, jantung, dan paru-paru pada usia kebuntingan bulan ke-6 atau hari ke-191.

Anoa is Sulawesi's endemic animal that is endangered due to poaching and habitat loss. Information regarding the management of anoa reproduction is still limited, so conservation efforts are hampered. Research related to reproductive management needs to be done to optimize the breeding of anoa. This study aims to determine the factors supporting the success of anoa pregnancy (Bubalus depressicornis CH Smith, 1827) through natural mating and detecting anoa pregnancy (Bubalus depressicornis CH Smith, 1827) through behavioral and morphological changes, measurement of urine biochemical profile, and transabdominal ultrasonography. The study was conducted at Anoa Breeding Center in Manado (ABC), North Sulawesi. The research data was collected in July- October 2017 to find out the estrous cycle, optimal mating time, and mating behavior, in March-May 2019 to verify the success of anoa natural mating during the April 2016-May 2019 period, and January -May 2019 for urine biochemical profile measurement. The study used 2 male Anoa and 4 Anoa. Pregnancy supporting factors were analyzed using path analysis with the help of SmartPLS software and discriminant analysis. Behavior and morphological change data were analyzed using Principal Component Analysis (PCA). The urine biochemical profile data were analyzed using the T-test. Transabdominal ultrasound data was analyzed descriptively. The results showed that there were variations in the length and duration of estrus among individual anoa. The length of estrous anoa cycles ranges from 14-24 days with estrous length of 2-4 days. Based on the results of SmartPLS, it is known that external factors (management and climate) and internal factors (male and female individuals) do not show any real influence on pregnancy. Based on Principal Component Analysis (PCA) analysis, it is known that the main characteristics of behavioral and morphological changes are that pregnancy becomes swollen nipples, swollen udders, shiny hair, enlarged and lowered abdominal shape, and increased frequency of eating. An increase in the value of glucose levels and total protein in the urine of a pregnant anoa occurs significantly that transabdominal ultrasound is not able to show the appearance of embryonic vesicles as an early sign of pregnancy. Transabdominal ultrasound clearly shows a picture of fetal organs, namely the breastbone, spine, head, heart, and lungs at the age of pregnancy in the 6th month or 191st day."

"Diosphyros celebica Bakh., also known as Sulawesi ebony, is an endemic to central and northern Sulawesi. Information about pollen dispersal patterns of D. celebica have not been previously investigated. This study was aimed to determine pollination type, percentage of selfing and outcrossing, as well as distance of pollen dispersal of D. celebica. This study was conducted at experimental forest of Universitas Hasanuddin, Maros District, South Sulawesi Province, Indonesia. One hundred and sixty six individuals of D. celebica consisted of adult trees and seedlings were analyzed in this study. Ninety four adult trees were selected to become parent trees. The trees were mapped with GPS coordinates . All samples were genotyped using four SSR markers loci. Parental analysis and determination of pollen dispersal patterns were carried out using Cervus 3.0.3. Results indicated that the evaluated markers were effective for assigning candidate of male parents to all evaluated seedlings. Donated pollens could come from male parents in any directions relative to female parent positions. Pollen dispersal pattern showed outcrossing pollination among different male parents (pollen donated trees). The results indicated that seeds were produced predominatly by outcrossing. Pollen dispersal reached up to 166 m. Pollen related processes were linked through female parents, pollinators availability and ecological environment. Simultaneous use of progeny genotyping, spatially explicit analysis of environmental variables and outcomes of plant–animal interactions, were the key elements for an expanded approach to gene flow analysis considering dispersal via pollen and seeds. Research on pollen dispersal of D. celebica should be carried out in other forest types, such as mixed forest and highland forest."

"Pengelompokkan sosial dan kondisi lingkungan yang tercipta di kebun binatang dapat memengaruhi perilaku reproduksi gajah sumatra. Penelitian ini bertujuan untuk mengevaluasi dan menganalisis perilaku reproduksi tahap pre-copulatory sebagai perilaku diurnal pada gajah sumatra (Elephas maximus sumatranus, Temminck 1847) jantan adolescence di Taman Margasatwa Ragunan. Penelitian dilakukan selama masa Pemberlakuan Pembatasan Kegiatan Masyarakat (PPKM) level 3 di DKI Jakarta. Waktu pengamatan dimulai pukul 08.00—14.00 WIB dengan interval waktu 15 menit selama 60 hari. Metode pengamatan yang digunakan adalah continuous focal sampling dan ad libitum untuk mengamati perilaku pre-copulatory meliputi flehmen, agonistic, reaching over, drive, erection, dan attempt mount. Penelitian pula dilakukan untuk mengamati perilaku harian dan perilaku interaksi sosial. Hasil penelitian menunjukkan perilaku harian dan interaksi sosial tertinggi gajah sumatra jantan adolescence di TMR yaitu makan (55,26%) dan conspecific play (0,96%). Gajah sumatra jantan adolescence hanya menunjukkan perilaku flehmen kepada gajah betina yang dikandangkan bersama dengan persentase sebesar 0,114% (0,107%: alpha female; 0,007%: betina subordinat). Perilaku flehmen ditunjukkan oleh gajah jantan adolescence saat betina urinasi di hari ke-11 hingga 14. Peneliti menyimpulkan bahwa gajah sumatra jantan adolescence yang terdapat di TMR sudah melewati inisiasi pubertas dengan menunjukkan perilaku reproduksi pre-copulatory yaitu flehmen kepada gajah betina dewasa.

Social groupings and environmental conditions in zoos can affect the reproductive behaviour of elephant. This study evaluated the pre-copulatory behaviour as diurnal pattern of adolescent male sumatran elephant (Elephas maximus sumatranus, Temminck 1847) at Taman Margasatwa Ragunan. Observations have been carried out sixty days during the implementation of the third level of community activity restrictions during the COVID-19 pandemic in the DKI Jakarta province, starting from 8 a.m. to 2 p.m. with an interval of 15 minutes. Continuous focal sampling and ad libitum were employed as study methods to observe the pre-copulatory behaviour, including flehmen, agonistic, reaching over, drive, erection, and attempt mount. Furthermore, the researcher observed daily and social interaction behaviour. Daily behaviour and social interaction behaviour of adolescent male sumatran elephant in TMR dominated by feeding (55.26%) and conspecific play (0.96%). The results showed that adolescent male sumatran elephant only performed flehmen behaviour to female elephant, caged together with 0.114% (0.017%: alpha female; 0.007%: subordinate female). Flehmen’s behaviour was shown by an adolescent male sumatran elephant when a female elephant urinated on days 11—14. Thus, this study reports that adolescent male sumatran elephant passed the initial of puberty by showing flehmen as precopulatory behaviour to female elephant."
