The daily activities of the proboscis monkey (Nasalis larvatus Wurmb) living inrubber forests are poorly understood. The objectives of the research were to studyits daily movement pattern and to determine the time proportion of daily behaviors.The movement of the monkeys was followed by researchers on foot. The behaviorswere observed by scan technique in 15 second intervals for 30 minutes. In rubberforests, lowlands (baruh) were places where the monkey began and ended dailymovements and also conducted most activities. Most inter-water movements of themonkey (about 70%) were conducted twice a day. Statistically, movement distanceand rainfall were negatively and significantly correlated (ґs = -0.58; p < 0.05; n = 14).The monkey spent more time for feeding in the morning and afternoon, and restingat midday. Most behaviors of feeding, resting, playing, and grooming (84.01%) wereconducted at a tree height of less than 15 m. The monkeys moved farther during thedry season to get water and did activities in accordance with height strata to getvarious foods, avoided disturbances, and got comfortable and safe places.

The rearing technology of green catfish larvae has not yet established. Hight mortality occurred in the early larval stages. This experiment was conducted to study the effect of temperature and dissolved oxygen on metabolic rate and survival rate of green catfish larvae. 3600 green catfish larvae with initial individual mean weights of 1.24 ±0.19 mg and lengths 5.85 ±0.71 mm (one day after hatching) were reared in the aquarium of 30 cm x 30 cm x 40 cm dimension. Treatments were done at 3 levels of temperature 27oC, 30oC, and 33oC; and 3 levels of dissolved oxygen 6.47 ml/L, 1.05 ml/L, and 0.78 ml/L and 3 replications. The result showed that temperature and dissolved oxygen was significant to the oxygen consumption. Oxygen consumption of 0.67 ±0.25 mg O2/h/g and 0.86 ±0.005 mg O2/h/g was highest in larval reared at 33oC and dissolved oxygen 6.47 ml/L for 3 weeks. The higher water temperature the greater the oxygen consumption. The oxygen consumption decline with decreasing dissolved oxygen in the water, indicating an axyconformer type. The temperature was not significant to the survival rate and growth of the larvae. However the effect of dissolved oxygen was significant to the growth rate (P<0.05). Growth rate of 25.69 ±0.55% was highest in larval reared at 6.47 mg/L for 3 weeks.

The study aimed to analyze the dynamics of the development of cortical and medullary cells of adrenal gland in the long-tailed macaque (Macaca fascicularis) during pre- and postnatal period. The samples of adrenal glands were taken from 5 fetuses aged 70, 85, 100, 120, and 150 days of gestation, a newborn aged 10, and an infant aged 105 days old. The samples of the adrenal glands were stained with hematoxylin-eosin and Masson trichrome (Goldner’s modification). The results showed that the fetal adrenal cortex consisted of a definitive and fetal zones, but in the late gestation (fetus aged 150 days of gestation), the transitional zone appeared between both zones. At the postnatal period, the definitive zone changed to glomerulosa zone, while the outer cells of the transitional zone changed to fasciculata zone which radially arranged. The results indicated that the fetal zone was present until birth and it will disappear gradually after birth. The medullary cells were found at the fetal stages as an irregular structure of small islands of chromaffin cells in the fetal zone. This structure migrated slowly to the center of the adrenal glands. The characteristics of mature chromaffin cells were found in the adrenal glands at postnatal period. In conclusion, the cortex adrenal of the newborn of long-tailed macaque consisted of zona glomerulosa, zona fasciculata, zona transitional, and the remaining fetal zone that has dissapeared gradually after birth.

This study was conducted with aim to tend out morphology of oesophagus and stomach of the cave swiflets (Collocalia linchi) at macroscopic and microscopic levels. The data revealed that esophagus was 2.93 cm in length and possessed no crop. The stomach was small and the isthmus was not clear. Mucosa of the esophagus was lined by stratified squoamus epithelium. Esophageal gland was mucous type. The glands were well developed and distributed along the esophagus. The external muscle layer consisted of inner circular and outer longitudinal layers. The stomach could be distinguished into proventriculus and ventriculus with no clear isthmus between them. The mucosa of proventriculus was lined by single columnar epithelium. The ventricular gland area was divided into cardiac, fundic and pyloric gland areas. The surface of ventriculus was lined with cuticula. In general the esophagus and stomach of the cave swiftlets were simple with no crop in the esophagus and isthmus in the stomach. These might be related with the kind of food and feeding behavior of this species.

This study was conducted to evaluate the success rate of non-penetrative pre slaughter stunning (NPPSS) and the factors that influence it in 460 Australian Brahman cross cattle. Observations were made on the handling of cattle, the implementation of NPPSS, the slaughtering process until the animal was declared dead. The results showed that the stunning success rate of NPPSS (SSR) was 74.35%. Ordinal regression analysis of the six observed parameters, three parameters have a significant influence on SSR: shooting placement area (ASP), shooting placement distance (DSP), and the presence of frontal and nuchal eminence (FE, NE). The ASP at the point of the cross line between two lines from the center of the dorsal eye to the center of the contralateral horn base, DSP at a low position (DSP<3 cm), and presence of FE gave a relatively low of SSR. Thus, it can be concluded that the SSR of the use of NPPSS in Indonesia is relatively low and is influenced by ASP, DSP, and the presence of FE and NE.

Terbang pada kelelawar merupakan moda gerak utama karena mereka adalah satu-satunya mamalia yang dapat terbang. Karakteristik morfologi membran sayap diduga berperan penting dalam kemampuan terbangnya. Penelitian ini menganalisis morfologi fungsional membran sayap kelelawar besar (Pteropus vampyrus), dengan fokus pada pengaturan serat elastis dan kolagen. Dalam penelitian ini, kami menggunakan dua kelelawar dewasa yang ditangkap di alam liar dari Jawa Barat, Indonesia. Potongan jaringan membran sayap diwarnai menggunakan pewarnaan hematoksilin-eosin, trikrom Masson, dan Verhoeff-Van Gieson. Membran sayap kelelawar terdiri dari kulit berlapis ganda yang ditutupi oleh lapisan epidermis tipis. Membran sayap terdiri dari serat kolagen dan bundel elastin yang tertata rapi yang disisipkan di antara dua lapisan kulit. Serat kolagen memperkuat membran sayap dengan menahan tekanan udara, sedangkan serat elastis memberikan fleksibilitas pada sayap. Hal ini dapat menggambarkan kekuatan dan fleksibilitas membran sayap kelelawar besar selama terbang.

The Sailfin lizard is a lizard that has a semi-aquatic life and has a sail fin on its tail. These lizards can be found in habitats close to water such as rivers, lakes, and estuaries of mangrove forests. This study aimed to observe the morphofunctional characteristic of the appendicular skeleton of Sailfin Lizard (Hydrosaurus amboinensis), associated with their function and behavior. The appendicular skeleton of the Sailfin lizard was studied morphofunctional by observing and measuring the bones that make up the extremities. The naming of bones and their parts is based on the Nomina Anatomica Veterinaria 2017 and other journals. The clavicle and interclavicle bones are located anterior to the scapula coracoid which has a convex shape. The patella ulnar bone is found at the humeroulnar joint and the radius et ulna bones have a relatively long antebrachial interosseous space. On the hind legs, the coxal bone has a relatively broad acetabulum, two lunula bones and patellar mineralization are found at the craniodorsal of the femorotibiofibular joint, and tibia et fibula bones have a relatively long crural interosseous space. The palmar part of the carpal bone is found in the palmar sesamoid bone, while the tarsi bones have a fused astragalus and calcaneus bones to become astragalocalcaneus bones. The pedis skeleton's size is relatively long compared to the manus skeleton and has a different middle phalanx bone. The extremity skeletal structure allows the Sailfin Lizard to do movements such as walking, running, climbing, running on water, and swimming.Key words: appendicular skeleton; morphofunction; Sailfin lizard.
