Abstract

The genus Macaca, member of sub-family Cercopithecinae, is the most widely distributed non-human primates in Asian countries. The habitats are strongly influence the dietary variation of the populations. The dietary variation of the macaques reflect ecological plasticity in coping with differences both in availability and abundance of food. The macaques are plastic in taking any kind of food that available in their home range and adjust their behaviour according to its abundance. Here, we present the dietary variation of long-tailed macaques (Macaca fascicularis) in the high altitude rain forest of Telaga Warna, West Java, Indonesia. The proportion of their food from natural sources is greater than those from visitors. The natural food consisted of plants, small animals (insects and earthworm), fungi and water from lake. The plant food comprised of 29 species plus a few mosses. The frequency of eating artificial food was influenced by visitors who come for picnic. In this site, the macaques learned that the visiting of tourists is identical with food.

Abstract

The physical growth that occurs in schoolage children is makes this period one of the most important phases in the human life cycle. Within this period, puberty is indicated by growth spurts that increase both stature (BH) and bodyweight (BW). The focus of this research is to evaluate the age-related body size variation in Sasak children living at different altitudes on the island of Lombok, Indonesia: low, medium, and high. Our results showed that children living at low altitude were taller and heavier than children of the same age living at medium and high altitudes. Up until the onset of puberty, the children at medium altitude have similar stature and weight to those residing at high altitude, but they are shorter and lighter thereafter. There were significant differences in the height and weight of girls in different altitude locations, but no significant difference for boys. The effect of SES on child growth can be comparison between Sasak and other populations in Indonesia. In general, the Sasak children are shorter and lighter than children of the same age in urban populations, and relatively similar in size to the children in rural populations. Indicators of socioeconomic status such as family income and parental education were shown to be more influential factors in the differentiation of physical growth between populations than the altitude factor

Abstract

The face is an important visual stimulus in daily life and each face identifies a particular person. The bone structure of the skull along with various soft tissues and coloration influence perception of the face. Facial averageness, and bilateral symmetry are the two most commonly used criterion of facial attractiveness, yet, both may be perceived differently based on hormonal status of the person observed. Facial perceptions may also differ according to cultural norms. In this research, we examined variations in face-shape among Sundanese male and female adults aged 18 to 40. We applied geometric-morphometric methods to analyze the landmark-based morphological variations in the frontal and lateral views of subjects’ faces. We identified five types of female frontal face views and four of male. We also identified five types each of female and male lateral face views. The trichion, gonion and gnathion were three most variable landmarks among the face views in our study, and highly determined the shape of the individuals’ faces. Multiple face type variation may refer to many categories of attractive faces since there is no exactly perfect category in the assessment of facial attractiveness by the viewers. Therefore, we believe that the configuration of facial features cannot constitute the sole visual criterion of facial attractiveness.

Abstract

The objectives of this study were to reveal ecological preferences and distribution of all species of Caridina found in Lake Lindu and their catchment area. Specimens from 39 sampling sites were caught using tray net and hand net. There are three species of Caridina found in the lake system, i.e. Caridina linduensis, Caridina kaili and Caridina dali. There is no overlapping distribution among the species. Caridina kaili is a true riverine species and it is never encountered sympatric with C. dali nor C. linduensis. This species is abundant in streams and ditches with moderate flow running water and gravel–cobble substrate. It is mainly spread within streams west to the lake. Both C. daliand C. linduensis can be found in the lake and streams with very slow current to almost stagnant water, muddy sand substrate and associated with roots of water plants and leaf litter. However, C. dali is never occurred together with C. linduensis and they are less abundant compare to C. kaili. Distribution of Caridina spp. in Lake Lindu is probably affected by the temperature of their habitats and the occurrence of introduced fish such as Mozambique tilapia (Oreochromis mossambicus), common carp (Cyprinus carpio), and an alien riceland prawn (Macrobrachium lanchesteri). These introduced and alien species can have the potency to become predators or competitors for the Caridina spp. It is also the first record for M. lanchesteri present in Lake Lindu.

Abstract

Reasoning is a process to solve the problem. This process needs cognitive functions in thinking, learning, and making decision. Cognitive style is a term to explain human natural preferences in gathering and processing information. Humans appears to reason using two cognitive processing styles; the first system is called as intuitive thinking style that is spontaneous, effortless, and without conscious search, whereas the second system is called as reflective or analytical thinking that works in a deliberate, analytical, procedural, and controllable process. In human context, sometimes people encounter difficult problem or unknown situation that have to be coped by ideas that are both novel and adaptive to the task constraints. People who solve the problem successfully are called creative. Creativity is the base to enhance competitiveness among students that might result in good academic performance. The present study examined cognitive style and creative quality in affecting academic achievement of university students in Indonesia. The result showed that students who used analytical thinking tended to have higher academic success, especially in life science majors. Moreover, it was found that students would need to materialize their creative potential to reach greater academic achievement in demanding classes; for instance, the final year of undergraduate program.

Abstract

Understanding body size growth pattern is one of the best ways to find out biological variation in phenotypic plasticity, health and nutritional statuses, and quality of life. Optimum environment and better nutrition are associated with rapid growth, tall stature, and early puberty. However, poor living condition impacts every stage of development, which results in variation in growth rates, growth periods, and body sizes across populations. Baduy is one of traditional populations who inhabit mountainous area in Kanekes Village, Lebak Regency, Banten Province, Indonesia. The traditional obligatory duties and taboos resulted in genetic, geographic, and cultural isolations. This leads to question whether the biocultural condition affects the growth pattern of their body size. We measured the body height, weight, and mass index of 340 girls and 239 boys aged 4–30 years sampled from 39 of 61 hamlets using cross-sectional method. We found that Baduy people had prolonged growth resulting in small body size because of slow rate and low spurt. This might be a selection to save body maintenance costs in biocultural condition with poor nutrition and high physical activity.

Abstract

Several small-scale populations exhibited phenotypic plasticity whereby growth spurt of body height occurred much earlier than age at menarche and this was not followed by same early spurt of body weight. This leads to question whether growth trajectory of stature follow the same growth trajectory of body mass and whether the trajectory itself is associated to sexual maturity. We evaluated developmental plasticity observed in Baduy girl, a traditional population in Indonesia, in facing strenuous environmental and biocultural conditions. We measured stature and body mass cross-sectionally. We determined age at menarche as population average of age of girls that had already got their first menstruation. Growths of body fat and weight followed a same mode and timing and their spurts pivoted on the age at menarche. In contrast, growth spurt of body height occurred four years earlier than menarche and velocity curve of body linearity progressed in opposite direction to that of body ponderality. The prevailing poor nutrition and high physical activity elicited principle of ontogenetic allometry to synchronize the acceleration and deceleration of growths in body linearity and ponderality whereby growth in body height functions to reach the body size target and to provide skeletal framework for development of body mass. The biocultural conditions lead to slow bodily growth rate with low spurt resulting in the characteristics of Baduy girl that was small in size and late in both sexual maturity and full-grown ages.

Abstract

Species detection and identification is a crucial steps in biodiversity assessment. Traditional methods are often invasive and resource intensive. The number of studies demonstrating successful of eDNA metabarcoding approach in species identification has increased rapidly in recent years. Some of large terrestrial mammals have reportedly utilize natural salt licks as a source of minerals in the diet and its genetic material left in the environment can be used to identify species from this site. An eDNA metabarcoding protocol had been carried out to identify Sulawesi mammals from Adudu natural salt-licks, Nantu Wildlife Reserve, Gorontalo. Environmental DNA were extracted from water samples, Amplicon libraries were prepared by PCR amplification and Illumina MiSeq high throughput sequencing. Reads processing and taxonomic assignment carried out in two bioinformatics packages, PipeCraft-1.0 and OBITools-2.11. Two endangered Sulawesi mammals species had been identified, i.e. lowland anoa (Bubalus depressicornis) and babirusa (Babyrousa babyrussa). The accuracy of mammal species identification using eDNA metabarcoding is affected by rigorous experimental procedures, DNA marker reliability, and availability of reference sequence database.

Abstract

The studies of parasites in buffaloes have not been widely explored. The aim of the present study was to explore the prevalence of gastrointestinal worm infection in buffaloes. The fresh faecal samples were collected from 89 buffaloes and observed by a modified McMaster technique. The faecal of buffaloes were collected in Bogor, Demak, East Java, and Lombok. The results of identification on gastrointestinal parasites show that there were one cestode and eight nematode. The total prevalence and infestation of cestodes and nematodes was found highest in Bogor. The prevalence and infestation of differences in geographical conditions were found highest in Bogor. The prevalence of gastrointestinal worm in males were highest than female, whereas for larger was found in females. The prevalence of gastrointestinal worms was found at age 1 year, whereas a larger infestation was found at the age of 1-5 years. The calculation of FEC in Bogor was 840 EPG, in Demak 375 EPG, in East Java 570 EPG and in Lombok 13 EPG. This study informed that there were nine genera of gastrointestinal worm found in Java and five genera in Lombok. Types larvae were found six i.e Strongyloides, Haemonchus, Cooperia, Oesophagostomum, Bunostomum and free living larvae.
