"ABSTRAK Tingginya permintaan jalak putih (Acridotheres melanopterus) di pasaran tidak diiringi dengan populasi yang melimpah di alam. Jalak putih pada saat ini sudah sulit ditemukan di alam liar dengan status Critically Endangered atau kritis (IUCN). Oleh karena itu manusia mulai melakukan penangkaran terhadap burung ini untuk memenuhi kebutuhan pasar ataupun sebagai usaha pelestarian. Banyaknya penangkaran yang bermunculan tidak dibarengi dengan cukupnya pengetahuan penangkar mengenai jalak putih. Kenyataan bahwa jalak putih terbagi kedalam tiga spesies tidak banyak diketahui oleh penangkar dalam mengawinkan jalak putih. Hal ini mengakibatkan banyaknya perkawinan silang baik sengaja ataupun tidak disengaja antar spesies jalak putih di penangkaran. Fenomena hibridisasi yang terjadi di penangkaran dapat menuntun jalak putih menuju kepunahan dikarenakan spesies murni perlahan hilang. Jalak Putih hibrida secara langsung dapat diketahui dari ciri-ciri morfologinya yang berbeda dengan spesies murni jalak putih. Secara morfologi, pengamatan langsung dapat dilakukan untuk mengidentifikasi ciri-ciri jalak putih hibrida. Hasil penelitian menunjukkan bahwa ciri utama yang membedakan jalak putih hibrida dengan murni terdapat pada bagian bulu punggung. Jalak putih hibrida memiliki bulu abu-abu di bagian punggung sedangkan jalak putih murni berwarna putih bersih. Hasil penelitian juga menunjukkan bahwa manajemen penangkaran jalak putih di Indonesia masih banyak didasarkan pada pengalaman. Belum ada penelitian yang secara khusus meneliti fenomena hibridisasi pada jalak putih sehingga hasil penelitian ini juga sangat penting untuk menghasilkan dasar-dasar pengetahuan mengenai jalak putih hibrida yang akan sangat bermanfaat bagi usaha pelestarian burung ini di masa depan.

ABSTRACT

The high demand for black-winged myna (Acridotheres melanopterus) on the market is not accompanied by an abundant population in the nature. Black-winged myna is now difficult to find in the wild with critical endangered or critical (IUCN) status, therefore humans began to capture these birds for the market needs or as a conservation programs. The number of captive breeding is not accompanied by sufficient knowledge of the breeders about the black-winged myna. The fact that black-winged mynas are divided into three species is not known by many breeders in mating the black-winged myna. This is making the risk of cross-breeding or hibridization higher whether intentionally or not between the species of black-winged myna in captivity. The hybridization phenomenon that occurs in captivity can lead the black-winged myna to extinction after the pure species are replaced by the hybrids. Hybrid black-winged myna can be identified directly from the different morphological characteristics compared to pure white starlings. Morphologically, direct observations can be made to identify the characteristics of hybrid black-winged myna. The results of the study show that the main features that belongs to the hybrids is can be found on the back feathers. Hybrid black-winged myna is having gray feather on the back while pure white starlings are pure white. The results also show that the management of black-winged myna captive breeding in Indonesia is still have a lot of tings to be fixed. There are no studies specifically for the hybridization phenomenon in the black-winged myna. The results of this study are also very important as a base to produce the basics management and information that will be very helpful for the conservation program of the birds in the future."

"The importance of conservation is growing each year, with increasing concerns over the destruction of biodiversity and the rising awareness of ecosystem services generating new debates on the human-nature relationship. This compact overview integrates the process, theory and practice of conservation for a broad readership, from students to practitioners. Taking a global perspective, it uses examples from around the world to show how general themes, patterns and drivers acting at different scales come together to cause problems at the local level"-- Provided by publisher."
