Fragmentation habitat affected homerange animals, which one is King cobra. King cobra was founded in palm oil plantation because palm oil plantation provide new habitat for king cobra. King cobra homerange overlaping with other king cobra’s but the homerange areas different, due to the difference of obervation time. Microhabitat temperature, environtment temperature and humidity influences homerange of king cobra’s.environmental factor also affect king cobra homerange. Daily activity of king cobra and human activity near the king cobra habit also affect the homerange. Hunting activity of king cobra most affected factor to changes homerange king cobra. The large avalaibility of prey leads to hunting area decrease and narrow the hunting area of king cobra. eywords : Radiotelemetry, king cobra, homerange, environment factor

This study aimed to examinine the physiological condition of Baung's blood (Hemibagrus nemurus Blkr.) on the Batang Ombilin River, West Sumatra. This research uses quantitative descriptive method where quantitative data in the form of physic value is presented through comparison table average. The results showed the physiology of blood of Baung fish (H. nemurus Blkr.) where the average amount of erythrocytes was similar in both sites where in Ombilin, the erythrocyte count had an average value of 2,268 x 106 cells/mm3 and in Sawahlunto 2,267 x106 cell/mm3. While for the average number of leukocytes of Baung fish (H nemurus Blkr.) In Sawahlunto is greater than the average number of fish leukocytes in Ombilin where in Sawahlunto with an average leukocyte count of 3,5x104 cells / mm3 and in Ombilin is 2,7x104 cells/mm3. And the blood hematocrit value of Baung fish. In Ombilin obtained a value of 38,8% and in Sawahlunto of 38,6%. As for the calculation of hemoglobin levels in both sites, hemoglobin levels were found in low levels of 8,5 g/dl in Ombilin and 5,4 g/dl in Sawahlunto. The levels of erythrocytes, leukocytes and blood hematocrit of Baung fish are at normal ranges. While hemoglobin levels at both sites were under normal conditions.

Tropidolaemus wagleri commonly known as complex species who widely distributed at tropical areas in Southeast Asia. We predicted that widespread distribution may affect the morphological variation among different population geographycally. This study were conducted based on direct survey and sampling in the fieldwork. The study sites was divided into two categories based on Bukit Barisan range which streching from North to South Sumatra island consist of Padang, Padang Panjang in western part of Bukit Barisan, and Payakumbuh, Dharmasraya in eastern part of Bukit Barisan. In total 21 individual T.wagleri were analysed based on 20 mensural characters (morphometric) and 19 multistate characters (meristic). Male and female was analysed separately based on non parametric statistics Kruskall Wallis and Mann Whitney U Test. The relationship between population were analysed based on UPGMA tree and Principal Component Analysis (PCA) plot. The result showed the significant variation between female T. wagleri between western and eastern part of Buki Barisan range. In contrast, the variation has not detected among the population of T. wagleri male. The morphological character which showed the significant value are Head Length (HL) and Neck Scales Row (NSR). The west population of T. wagleri has more shorter Head Length (HL) and Snouth Length (SnL) than east population. Howefer, the west T. wagleri population has more number in Neck Scales Row (NSR) character than east population. The population of female T. wagleri in Padang Panjang has more close relationship to Padang than to female population T. wagleri in Dharmasraya based n UPGMA tree.

Fragmentasi habitat mempengaruhi daerah jelajah beberapa jenis hewan, salah satunya adalah ular king kobra (Ophiophagus Hannah Cantor, 1836). King kobra saat ini sering ditemukan di daerah sekitar perkebunan sawit karena perkebunan sawit menyediakan habitat baru bagi king kobra. Daerah jelajah king kobra di area perkebunan sawit perlu diketahui luasnya, agar dapat dimanfaatkan sebagai indikator lingkungan dan pengendali populasi hewan lainnya termasuk hama. Untuk mendapatkan data luas daerah jelajah king kobra dapat dilakukan dengan cara observasi dan teknik radiotelemetri. King kobra memiliki daerah jelajah yang saling berhimpitan antara satu dan yang lainnya namun luas daerah jelajahnya berbeda, disebabkan oleh perbedaan waktu pengamatan. Suhu mikrohabitat, suhu lingkungan dan kelembapan memberikan pengaruh terhadap luas daerah jelajah king kobra. Faktor lingkungan juga mempengaruhi luas daerah jelajah king kobra. Aktifitas harian king kobra dan aktifitas harian manusia juga mempengaruhi luas daerah jelajah king kobra. Aktifitas berburu king kobra merupakan pemberi dampak terbesar terhadap perubahan luas daerah jelajah king kobra tersebut. Banyaknya ketersedian makanan menyebabkan area berburu menjadi kecil dan mempersempit ruang berburu dari king kobra.Kata kunci: Radiotelemetri, king kobra, daerah jelajah, faktor lingkungan
