Human brain posseses the ability to create a concept to assist the process of grouping individual object or events into different classes or categories. We call this grouping process as categorization. In addition to humans, the ability to categorize has also been proposed for animals. Being able to identify, visually or otherwise, a new object as a member of a category is an advantage for animals.

Abstract

Human brain posseses the ability to create a concept to assist the process of grouping individual object or events into different classes or categories. We call this grouping process as categorization. In addition to humans, the ability to categorize has also been proposed for animals. Being able to identify, visually or otherwise, a new object as a member of a category is an advantage for animals. Present experiment aims to test the categorization ability in discriminating species by Macaca fascicularis. Using match-to-sample task with photographs of monkeys and human as stimuli, we tested whether monkeys able to categorize monkey individuals as a class against human individuals as another class. We found that monkeys categorized humans differently from monkeys. The monkeys used physical characteristic such as shape and colors from the photographs to create different concepts of human and monkeys.

Abstract

Papuan white snake (Micropechis ikaheka) is endemic to New Guinea (the region of the Papua and Papua New Guinea). Internal histology of skin layer and the microtopography structure on the surface scales of M. ikaheka were the aims of the study. This study also related to zoogeographical of the snake in Papua. Geographical skin color variation of M. ikaheka can be described in three groups, i.e. brown, yellow and black group. The three groups of the snake have specific zoogeography in the mainland of Papua and satellite islands to Papua New Guinea. Paraffin method used in this work showed approximately five layers i.e. oberhautchen, the beta (b)-layer, the mesos layer, the alpha (a)-layer, and the dermis in the snake skin. Although the paraffin method cannot explain the arrangement of pigment cells, however, the dark color on the dermis might contain melanophores that might cause dark color of the snake body. Overlapping scales formed the hinge region were flexible to assist the snakes when they moved across substrate. Scanning electron microscopy (SEM) of the oberhautchen of all of M. ikaheka revealed no microornamentation. However, dorsal and ventral scales showed many follicles on the entire surface of the boundary scales.

Abstract

Limited data is hitherto available on the diversity and dispersal of parasitic mites of geckos in Indonesia. Here, we collected three species of geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii throughout Indonesia to study the distribution and diversity of its parasitic mites. We conducted detail morphological analysis of the mites using whole mount polyvinyl lactophenol and scanning electron microscope preparation. Three species of ectoparasite mites from genus Geckobia were identified in a total of 221 individuals out of 448 geckos collected from 25 sites in Indonesia. Two species were G. glebosum and G. bataviensis, and the other one was designated as Geckobia sp 1. Based on our result, the three mites species were spread randomly and live sympatrically. The G. bataviensis mite showed the widest distribution, because it was found in almost all gecko collection sites, hence the most cosmopolitan mites. We also found that C. platyurus gecko had the lowest mite prevalence which might due to the fact that it has the least number of skin folds, an important site for mite protection. This result implies that further research on the relationship of anatomy of gecko skin with chelicera and claw structure of mites is necessary in the future.

Abstract

Green turtle (Cheloniamydas; Testudines) is included in the group of polyandryanimals, which is single female mated with many male. DNA polymorphism method generally considered to have a high degree of accuracy as compared to other methods to elucidate polyandry phenomena on many animals. In this research, three microsatellite loci were used to identify the number and frequency of genotypes per locus, the number and frequency alleles per locus, and genotypes and number of alleles in the nest. The purpose of this research was to study the reproductive pattern of Cheloniamydas and compensation eggs of males from hatchling’s population in turtle conservation area of Pangumbahan Coastal Park, West Java. The result showed that from 10 nests, we could find 37 genotypes with 11 alleles for D108 locus, 21 genotypes with 9 alleles for B103 locus, and 27 genotypes with 9 alleles for C102 locus. The alleles number of each nest was more than 5 alleles for 5 nests, and more than 4 alleles for the remaining nests. Based on the probabilities of alleles contribution of each parent, the green turtle was polyandry animals.

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

Anoa is an endemic ungulate in Sulawesi and its status now is endangered because the population continues to decline. Conservation genetics is one of the crucial issues in the anoa conservation strategy and action plan 2013-2022 document, but this genetic data is not yet available. To investigate and provide valuable information for conservation genetics measures, thirteen polymorphic microsatellites were used to analyze 20 adult anoa. Anoa has relatively low genetic diversity within populations (HO = 0.58), and high genetic differentiation among populations (FST = 0157). Although the anoa population has a bottleneck signal (T.P.M: 0.019; P0.05), the bottleneck simulation results show that the loss of genetic diversity is being slow over the next 100 years (9.5%). We provide some recommendations for conservation genetics based on the findings in this paper, including monitoring and genetically mapping for other anoa populations due to bottleneck signals, establishing the founder of the ex-situ population by examining their genetic diversity status, maintaining and increasing the number of individuals in the ex-situ population to genetically safe population size, and managing anoa populations by avoiding inbreeding. In-situ and ex-situ conservation programs should be combined to maintain the genetic diversity of anoa.

Abstract

In Indonesia, the sand crab Albunea symmysta distribution includes Java, Sumatra, and Moluccas. Populations are assumed to be differentiated between western and eastern Indonesia due to the Wallace line; however, no information on the genetic diversity and differentiation of A. symmysta in Indonesia is available. This study was conducted to clarify the genetic diversity and differentiation of A. symmysta in Indonesia. During the sampling campaign, A. symmysta specimens were found only in Java and Papua. Genetic analysis based on the 643-bp fragment of the partial COI gene from 32 individuals revealed significant genetic differentiation between the Java and Papua populations (FST = 0.94, p < 0.005). The haplotype connectivity of the five A. symmysta sampling sites revealed a two-clade network. Based on analysis of molecular variance, most of the variation was found among populations (94.21%) rather than within populations (5.79%). Tajima's D and Fu's FS values indicated a population expansion. Overall, the findings support a high level of differentiation between the Java and Papua A. symmysta populations, suggesting the separation of population stocks due to low connectivity.

Abstract

Gallus varius, an indigenous bird species of Indonesia, demonstrates significant genetic diversity. The genetic diversity assessment in G. varius encompassed both mitochondrial DNA (mtDNA) and nuclear DNA, with the mtDNA analysis primarily centered on domain I of the control region. This study aimed to describe the genetic diversity and structure of G. varius inhabiting Java, Madura, Lombok and Sumbawa based on the middle-lower part of control region mtDNA. Genomic DNA was extracted from the calamus tip of feather, then the middle-lower part of control region was amplified and sequenced using two pairs of primers. In the examined control region, spanning from 944 to 1,008 bp, 13 bp of nucleotide variation was observed, with nucleotide diversity at 0.0021. Between G. varius samples and the reference (NC_007238.1), a total of 7 haplotypes were identified, 5 unique and 2 shared haplotypes, with haplotype diversity at 0.7692. The substantial diversity of haplotypes in this study and two previous study suggests that the genetic diversity of G. varius has remained stable over the past two decades. Additionally, genetic distance data indicate there is multiple G. varius subspecies, and the haplotype network accentuates signs of population differentiation.

Abstract

We conducted a preliminary survey of the wild common palm civet Paradoxurus hermaphroditus in a secondary forest in Pangandaran Nature Reserve, West Java, Indonesia. We collected 125 fresh fecal samples between October 2018 and August 2019. We conducted faecal analyses after species confirmation by camera trapping and faecal DNA analysis. Almost all faeces contained fruits and seeds (frequency of occurrence: 97.6%), while the percentage of animal matter (including mammals, birds, insects, non-insect arthropods, and molluscs) was much lower (22.4%). We observed no seasonal differences in major faecal contents. Higher dependence on fruits by the common palm civets was similar to those in other study sites. Seeds of at least eight different plant species were found in the faeces of the common palm civets, which implied that the common palm civets would play roles as seed dispersal agents.

Abstract

The crowing of male Gallus exhibits diverse sound patterns. This is believed to be related to the phenotypic diversity of vocal organs, one of which is influenced by the nucleotide diversity of the associated genes. The SOX9 gene, involved in cartilaginous tissue growth and development, is reported to contribute e in the development of larynx and syrinx. This study aimed to characterize the CDS regions of exons 1 and 2 of the SOX9 gene in junglefowl to assess its diversity. Genomic DNA was extracted from ten individuals of G. varius from Lombok and Sumbawa. The CDS regions of SOX9 gene exons 1 and 2 were amplified using two primer pairs. Additionally, the CDS regions of SOX9 gene exons 1 and 2 from 54 junglefowl SRA data in an online repository were mapped and analyzed. The study identified all nucleotide sequences as CDS regions of SOX9 gene exons 1 and 2. Six shared, and 24 unique haplotypes were constructed. A putative amino acid sequence common to all Gallus species was also identified. The diversity observed in the CDS regions of SOX9 gene exons 1 and 2 nucleotide sequence showed a different level with the diversity observed in its amino acid sequence.
