Endoparasite infestation of Indian Muntjac (Muntiacus muntjak) in Citra Pesona Ladangku Animal Park, North Sumatra

An investigation on the infestation by endoparasites in the fecal samples of Indian Muntjac (Muntiacus muntjak) captived at Citra Pesona Ladangku Animal Park, North Sumatera, Indonesia had been conducted from October to November 2020. The study aimed to determine the endoparasite species, prevalence, and intensity of the infestation. Fecal samples were prepared for microscopical examination using glass bead sedimentation method. Based the observation on 9 deers, three species of endoparasites were found namely Ascaris sp, Haemonchus sp and Paramphistomum sp. Observations in the first week revealed the prevalence of each species from often (Ascaris sp, Haemonchus sp) to common (Paramphistomum sp) with light (Haemonchus sp, Paramphistomum sp) to moderate (Ascaris sp). Observations in the second week only revealed the presence of Paramphistomum with often prevalency and light intensity of infection.

Analysis of muntjac deer genome and chromatin architecture reveals rapid karyotype evolution

Closely related muntjac deer show striking karyotype differences. Here we describe chromosome-scale genome assemblies for Chinese and Indian muntjacs, Muntiacus reevesi (2n = 46) and Muntiacus muntjak vaginalis (2n = 6/7), and analyze their evolution and architecture. The genomes show extensive collinearity with each other and with other deer and cattle. We identified numerous fusion events unique to and shared by muntjacs relative to the cervid ancestor, confirming many cytogenetic observations with genome sequence. One of these M. muntjak fusions reversed an earlier fission in the cervid lineage. Comparative Hi-C analysis showed that the chromosome fusions on the M. muntjak lineage altered long-range, three-dimensional chromosome organization relative to M. reevesi in interphase nuclei including A/B compartment structure. This reshaping of multi-megabase contacts occurred without notable change in local chromatin compaction, even near fusion sites. A few genes involved in chromosome maintenance show evidence for rapid evolution, possibly associated with the dramatic changes in karyotype.

Karakter Morfologi Rambut Kelompok Cervidae Indonesia

Identification through animal hair character is one of a very important forensic tool given the high level of animal trade in Indonesia, one of which is the deer family (Cervidae). Indonesia has four species of Cervidae, there are Rusa timorensis (Javan deer), Rusa unicolor (Sambar deer), Muntiacus muntjak (Barking deer) and Axis kuhlii (Rusa Bawean). Until now, no information about the morphological character of Indonesian cervidae’s hair. In this study, we used 30 shaft/individual/species from Javan deer (8 individuals), Sambar deer (5 individuals), Barking deer (5 individuals) and Bawean deer (5 individual) from specimens collection of Museum Zoologicum Bogoriense (MZB) and field collections. Hairs were analyzed for macroscopic and microscopic, with several parameters of morphology, cuticular structure, medula, cross-section, and medullary index. The result showed that the special character of this family was filled lattice medulla structure and can be used for species identification.

Differences of terrestrial mammal species diversity between natural forest and edge forest areas in Batutegi Protected Forest, Lampung, Indonesia

This research is an explorative quantitative survey by testing differences in species of terrestrial mammals found in natural forest (core) and edge forest (ecoton) areas. The data collection was obtained by using camera traps installed for 3 months based on a grid cell 2 x 2 km, with a total of 16 camera traps placed in core area and another 17 were in ecotone. The object of this research was medium (0.3 kg) to large terrestrial mammals. The t test was used to determine the differences the species diversity of mammals between two research areas. The study shows that there are 22 species of terrestrial mammals with a total of 552 individuals, which is distributed in both research areas. In the core area there are 18 species with 237 individuals, while in the ecotone there are 18 species with 315 individuals. Analyses the species richness index was 17.8171 for the core area while 17.8262 for the ecotone area. Similarity index in both study areas ranged from 0.7106 to 1. While the value of diversity index (Shannon-Wiener) in the core area H '= 2.2038 and in the ecotone area H' = 2.0541. Three species with the greatest relative abundance values are Porcupine (Hystrix brachyura), Barking Deer (Muntiacus muntjak), and Wild Boar (Sus scrofa). Based on the t tests of the two research areas, which are core area and ecotone, obtained tcount 0.41365 (p 0.05), it can be interpreted that the diversity of terrestrial mammals species in the core and ecotone areas is not the same.Penelitian ini merupakan penelitian kuantitatif survei eksploratif dengan melakukan pengujian perbedaan terhadap jenis mamalia teresterial yang ditemukan di wilayah hutan alam (inti) dan wilayah hutan tepi (ekoton). Pendataan mamalia teresterial menggunakan camera trap yang dipasang selama 3 bulan berdasarkan grid cell 2 x 2 km, dengan 16 camera trap dipasang di areal inti dan 17 lainnya di ekoton. Objek penelitian adalah mamalia teresterial berukuran sedang (0,3 kg) hingga mamalia besar. Uji t digunakan untuk menentukan perbadaan keragaman jenis mamalia teresterial pada dua areal penelitian. Hasil penelitian menunjukkan terdapat 22 jenis mamalia teresterial dengan total 552 individu, yang tersebar di kedua areal penelitian. Pada areal inti terdapat 18 jenis dengan 237 individu, sedangkan pada areal ekoton ditemukan 18 jenis dengan 315 individu. Analisis indeks kekayaaan jenis menunjukkan nilai 17,8171 untuk areal inti dan 17,8262 untuk areal ekoton. Indeks kemerataan pada kedua areal penelitian berkisar antara 0,7106 hingga 1. Sedangkan nilai indeks keragaman (Shannon-Wiener) pada areal inti H’ = 2,2038 dan pada areal ekoton H’= 2,0541. Tiga jenis mamalia teresterial dengan kelimpahan relatif terbesar yaitu Landak (Hystrix brachyura), Kijang (Muntiacus muntjak), dan Babi hutan (Sus scrofa). Berdasarkan uji beda terhadap dua areal penelitian yaitu areal hutan alam (areal inti) dan areal tepi hutan (ekoton) didapatkan thitung 0,41365 (p 0,05), maka dapat diartikan bahwa keragaman jenis mamalia teresterial di areal inti dan ekoton tidak sama.

Timor Deer (Cervus Timorensis) Arrest System Marind People with Tidal Local Wisdom

Deer are wildlife that has economic value because it can produce meat, leather, and velvet (young horn). Deer populations in nature have decreased due to uncontrolled wild poaching and damage to habitat. Indonesia has five types of deer, i.e., Cervus unicolor, Cervus timorensis, Axis kuhlii, Muntiacus Muntjak, and Axis axis (deer total). However, deer in Indonesia that have the opportunity to be empowered, there are several types, namely Cervus timorensis, Cervus unicolor and Axis axis, and in Merauke, especially in the had tribe0 has its distinctive characteristic in the process of catching deer. The purpose of the study was to know the pattern of deer arrest by the Malind tribe. The method used in this research is to conduct surveys and Wawan ways as well as observation of the field, the data in the analysis in a descriptive approach to conclude the investigation. The results showed that the pattern of deer caught in the Marind tribe traditionally done with snares, bamboo rinsing, as well as patterns carried out covering the forest burning Sawvana in the dry season of the cattle, besieged fire and dwelling on the land, and the season The community rained to the deck area (dense forest) that became the deer's dwelling and avoided the puddle of the sea, and the community captured it quickly. The chance of this research is the process of catching deer, in general, is done by the had in 2 ways that in the summer by burning and drought with the trap system.
