Abstract: The ranging behaviour of translocated problem tigers is poorly understood. The demand for releasing problem tigers back to the wild increases following the increasing the number of problem tigers that needs to be rescued in Sumatra in the last decade. In this study we estimate the home range size and obtain information on daily range of four translocated problem tigers, as well as discussing some potential factors determining the size of home range and their movement. We translocated four adult males Sumatran tigers (Panthera tigris sumatrae) caught after killing domestic animals or rescued from traps set up by villagers for capturing deer and wild boar. The tigers were released following 16-225 days rehabilitation. All were fitted with global positioning system collars and released 74-1,350 km from their capture site. The length of time needed by each tiger for establishing home range was between 6 and 13 weeks. The home range size of each individual tiger estimated with 100% minimum convex polygon varies between 67.1 km2 and 400 km2, while estimations with a 95% fixed kernel methods were between 37.5 km2 and 188.1 km2. The difference in home range size established by each translocated tigers indicates the variability of the range size even within a subspecies. The maximum distance moved each tiger in one day was different, the range was 8.5-18.9 km. Although preliminary, these data may be useful for improving future translocation of problem tiger, as this study was the first ever conducted in Sumatra.

Abstract: Sasmita P. 2010. Evaluation of uniformity, variability, and stability of agronomic traits of doubled haploid rice lines resulting from anther culture. Nusantara Bioscience 2: 67-72. The formation of doubled haploid lines in anther culture aims to accelerate the acquisition of pure lines. Selection of the desired traits can be done directly to the progeny of anther culture results at early generations. This experiment aims to determine agronomic traits , uniformity, and stability of the doubled haploid lines, and obtain the putative doubled haploid lines as the material for further evaluation to obtain expected lines. The first experiments used completely randomized design which was repeated five times. The treatments were 111 doubledd haploid lines of first generation of anther culture results (DH1). The second experiment used split plot design with the main plot treatments were doubled haploid lines resulting from anther culture and the sub plot treatment were the second generation of doubled haploid lines (DH2) until the fifth generation (DH5). The results show that each plant within the same line have uniform agronomic traits, while the plants between different lines have different agronomic traits. The results of further evaluation on three out of 111 doubled haploid lines derived from the second to fifth generations show no difference between generations for each trait of the same lines. The results also show that the agronomic traits of the doubled haploid line were stable from generation to generation.

Abstract: Sasmita P. 2011. Evaluasi keseragaman, keragaman, dan kestabilan karakter agronomi galur-galur padi haploid ganda hasil kultur antera. Bioteknologi 8: 10-17. Pembentukan galur haploid ganda dalam kultur antera bertujuan untuk mempercepat perolehan galur murni. Seleksi karakter yang diinginkan dapat dilakukan langsung terhadap progeni hasil kultur antera pada generasi awal. Percobaan ini bertujuan untuk mengetahui karakteristik agronomi, keseragaman, dan kestabilan galur haploid ganda, serta mendapatkan putatif galur-gallur haploid ganda sebagai bahan evaluasi lebih lanjut untuk mendapatkan galur harapan. Percobaan pertama menggunakan rancangan acak lengkap diulang lima kali. Perlakuannya aadalah 111 galur haploid ganda hasil kultur antera generasi pertama (DH1). Percobaan kedua menggunakan rancangan petak terpisah dengan perlakuan petak utama adalah galur haploid ganda hasil kultur antera dan perlakuan anak petaknya generasi galur haploid ganda kedua (DH2) hingga kelima (DDH5). Hasil percobaan menunjukkan bahwa setiap tanaman dalam galur yang sama memiliki karakter agronnomi seragam, sedangkan tanaman antar galur berbeda memiliki karakter agronomi beragam. Hasil evaluasi lebih lanjut terhadap tiga dari 111 galur haploid ganda yang berasal dari generasi kedua hingga kelima menunjukkan tidak terdapat perbedaan karakter antar generasi untuk setiap p galur yang sama. Hasil penelitian tersebut menunjukkan pula bahwa karakteristik agronomi galur haploid ganda stabil dari generasi ke generasi.
Presurgical Nasoalveolar Moulding—An Adjunct to Facilitate Surgical Repair in Infants with Cleft Lip and Palate  [PDF]

Abstract:

Presurgical orthopedics forms an integral part of the treatment of patients with facial clefting. The primary aim of presurgical nasoalveolar moulding (PNAM) is reduction in the soft tissue and cartilaginous deformity to facilitate surgical soft tissue repair in optimal conditions under minimum tension to minimize scar formation. It also helps in reducing the nasal deformity with a nasal stent which brings the deformity near to the normal and forms an important part of the primary nasal repair at the time of primary lip repair. A soft acrylic relining material is added or removed to line the appliance to a thickness of approximately 1 - 1.5 mmin the region from where the bone is to be resorbed or apposed. This article describes the fabrication procedure of the modified nasal alveolar molding appliance in eight infants with unilateral cleft lip and palate in whom a significant reduction in cleft width and nasoalveolar deformity was achieved. The results showed that the greater segment shows more favourable changes and can be molded more positively and efficiently than the lesser segment.

Abstract: Large carnivores living in tropical rainforests are under immense pressure from the rapid conversion of their habitat. In response, millions of dollars are spent on conserving these species. However, the cost-effectiveness of such investments is poorly understood and this is largely because the requisite population estimates are difficult to achieve at appropriate spatial scales for these secretive species. Here, we apply a robust detection/non-detection sampling technique to produce the first reliable population metric (occupancy) for a critically endangered large carnivore; the Sumatran tiger (Panthera tigris sumatrae). From 2007–2009, seven landscapes were surveyed through 13,511 km of transects in 394 grid cells (17×17 km). Tiger sign was detected in 206 cells, producing a naive estimate of 0.52. However, after controlling for an unequal detection probability (where p = 0.13±0.017; ±S.E.), the estimated tiger occupancy was 0.72±0.048. Whilst the Sumatra-wide survey results gives cause for optimism, a significant negative correlation between occupancy and recent deforestation was found. For example, the Northern Riau landscape had an average deforestation rate of 9.8%/yr and by far the lowest occupancy (0.33±0.055). Our results highlight the key tiger areas in need of protection and have led to one area (Leuser-Ulu Masen) being upgraded as a ‘global priority’ for wild tiger conservation. However, Sumatra has one of the highest global deforestation rates and the two largest tiger landscapes identified in this study will become highly fragmented if their respective proposed roads networks are approved. Thus, it is vital that the Indonesian government tackles these threats, e.g. through improved land-use planning, if it is to succeed in meeting its ambitious National Tiger Recovery Plan targets of doubling the number of Sumatran tigers by 2022.

Abstract: one of the tactics that improved the control of rhyacionia buoliana in chile was the introduction in 1987 of orgilus obscurator, a specific parasitoid. evaluations between the regions vii and x of chile during 1995 to 1997 have shown significant differences in the establishment and parasitism obtained by o. obscurator. several factors are involved in the success of control strategies, including the availability and access to food sources such as water, flower nectar and honey, and its effect over longevity of adult parasitoids. the objective of this study, conducted during 1996-1997 and 1997-1998 in valdivia province, x region, was to consider these factors. for the experiment, 295 males and females of o. obscurator were maintained with water, honey and flowers of four species (three belonging to apiaceae and one to asteraceae). the highest longevity was obtained using honey (23 days for males, 33 days for females) and flowers of conium maculatum l. and daucus carota l. with an average of 14.1 days. these results suggest that increasing the presence of food sources in plantations of pinus radiata, mainly in the vii and viii regions, will enhance levels of parasitism by o. obscurator
