Study of Sumatran Tiger (Panthera tigris sumatrae) Breeding Season in Conservation Institution in Indonesia.
No full textThe aim of the study is to find out the reproduction pattern especially breeding season of sumateran tiger in ex-situ habitat or conservation institution (zoo and safari park) in Indonesia. The reproductive data were obtained from sumateran tiger regional and international studbook 2004-2010. The time of breeding were decided from the time of birth subtracted by the number of average pregnancy duration that range from 95 to 110 days or three months. The result of this study showed that sumateran tiger breed throughout the year; therefore, the sumatran tiger in conservation institution in Indonesia are non-seasonal breederr.Harimau Sumatera merupakan satu-satunya subspesies dari Panthera tigris yang masih ada di Indonesia. Harimau Sumatera diklasifikasikan oleh CITES ke dalam Appendix I critically endangered oleh IUCN. Kajian ini bertujuan untuk mengetahui pola reproduksi khususnya musim kawin harimau Sumatera yang berada di habitat ex-situ atau lembaga konservasi di Indonesia. Data didapatkan melalui penelusuran daya reproduksi harimau Sumatera berdasarkan studbook harimau Sumatera regional dan internasional tahun 2004-2010. Data dianalisis secara deskriptif untuk status reproduksi meliputi jumlah anak per kelahiran, musim kawin dan masa produktif. Bulan perkawinan dapat ditentukan berdasarkan bulan terjadinya kelahiran. Penghitungan bulan perkawinan didapatkan dengan cara mengurangi tanggal kelahiran anak dengan rataan lama kebuntingan harimau yang berkisar antara 95 sampai 110 hari atau lebih kurang tiga bulan. Hasil penelusuran dari studbook didapatkan bahwa perkawinan harimau Sumatera merata setiap bulan dalam satu tahun sehingga pada harimau Sumatera yang hidup di lembaga konservasi di Indonesia tidak mempunyai musim kawin

DNA sexing of Sumatran Tiger (Panthera tigris sumatrae) based on amelogenin genes
No full textNowadays, forensic and wildlife research, especially the Sumatran tiger needs further research with a molecular approach. Molecular approaches are needed for forensic and wildlife research including for sex identity. This study used the amelogenin gene as a marker for identification based on previous studies of Felidae species. The sample used consisted of 10 blood samples from Sumatran tigers of known sex were collected by the Dharmasraya Sumatran Tiger Rehabilitation Center (PRHSD), one hair sample, and two bone samples whose sex was unknown were collected from Natural Resources Conservation Center West Sumatra (BKSDA). The PCR results of the amelogenin gene of the Sumatran tiger confirmed the sex of 10 samples of known sex’s Sumatran tiger (Four male samples and six female samples), and Three samples of unknown sex were identified as females. Male was characterized by the electrophoresis appearance of two bands, while in female’s only one band, with PCR product sizes of at least 190 bp for AMELY and at least 210 bp for AMELX

Daily Behavior of Sumatran Tiger (Panthera tigris sumatrae Pocock, 1929) at Dharmasraya Sumatran Tiger Rehabilitation Center, Arsari Djojohadikusumo Foundation
No full textIn supporting the Sumatran tiger translocation and release program from rehabilitation centers to the wild, a behavioral study is needed as one of supporting tools for the success of the translocation and released program. This research aimed for understanding the daily behavior and the level of habituation of Sumatran tigers to human that have been rehabilitated at the Dharmasraya Sumatran Tiger Rehabilitation Center (PR-HSD) ARSARI. Observations of daytime behavior were conducted through direct observation, while night time observations were carried out using camera traps with and instantaneous scan sampling method at intervals of 2 minutes. The research focused on the two individuals, male tiger (Putra Singgulung) and female tiger (Ria). The research reveals that resting behavior was the most frequently observed in Putra Singgulung, accounting for 63.47%. Putra Singgulung displayed stereotyped behavior more prominently during the night accounts for, at 53.04%. For Ria, hiding behavior was the most common during the day, making up 96.30% of her observed behavior, while night time observation showed that Ria engaged in a significant amount of locomotion behavior, at 62.18%. Based on highly contrasting observations of behavior, it was found that the level of habituation for Putra Singgulung is high, while for Ria, it is low. Therefore, it can be conclude from the behavioral observations that the likelihood of release for Ria is higher than for Putra Singgulung
Pioneering Conservation Efforts with Crowdfunding Scheme for the Sumatran Tiger Conflict
No full textHuman-wildlife conflicts present significant challenges in conservation efforts. This study delves into the effectiveness of crowdfunding, intervention mechanisms, and communication initiatives in addressing the human-wildlife conflict, specifically concerning the sumatran tiger. By leveraging data from NGO web platforms, exploratory documentation, national records, and a broad spectrum of literature reviews, we aimed to unravel the nuanced dynamics of these initiatives in the conservation framework. Our findings indicate that while crowdfunding platforms such as the sapu jerat campaign offer innovative fundraising avenues, the harmonized efforts of communication strategies and robust intervention mechanisms create lasting impacts. This study underscores the essence of multifaceted approaches, stressing the value of stakeholder collaborations, including NGOs, local communities, and governmental agencies. Furthermore, this research accentuates the increasing role of digital tools in enhancing conservation efforts, suggesting a paradigm shift in contemporary conservation strategies. Hence, this study offers invaluable insights for conservationists, decision-makers, and NGOs aiming to optimize their strategies in the context of human-wildlife conflicts. At a more detailed level, the intervention mechanisms of the Sumatran Tiger Project demonstrate the importance of adaptive management, inter-agency collaboration, and sustainable financing as key components. This study highlights that the combination of technology, community involvement, strategic planning, and effective storytelling can provide a sustainable future for the sumatran tiger.
 
Automatic detection of potentially illegal online sales of elephant ivory via data mining
No full textIn this work, we developed an automated system to detect potentially illegal elephant ivory items for sale on eBay. Two law enforcement experts, with specific knowledge of elephant ivory identification, manually classified items on sale in the Antiques section of eBay UK over an 8 week period. This set the “Gold Standard” that we aim to emulate using data-mining. We achieved close to 93% accuracy with less data than the experts, as we relied entirely on metadata, but did not employ item descriptions or associated images, thus proving the potential and generality of our approach. The reported accuracy may be improved with the addition of text mining techniques for the analysis of the item description, and by applying image classification for the detection of Schreger lines, indicative of elephant ivory. However, any solution relying on images or text description could not be employed on other wildlife illegal markets where pictures can be missing or misleading and text absent (e.g., Instagram). In our setting, we gave human experts all available information while only using minimal information for our analysis. Despite this, we succeeded at achieving a very high accuracy. This work is an important first step in speeding up the laborious, tedious and expensive task of expert discovery of illegal trade over the internet. It will also allow for faster reporting to law enforcement and better accountability. We hope this will also contribute to reducing poaching, by making this illegal trade harder and riskier for those involved
PAT-1 Case report: Metastatic ganglioneuroma in a Sumatran Tiger
No full textNeuroblastic tumors, which are uncommon tumors of nerve cell origin, are classified into neuroblastoma, ganglioneuroblastoma, and ganglioneuroma depend-ing on the degree of maturation of neoplastic neuroblasts and development of schwannian stroma [2,4,7]. Ganglioneuroma is a rare neuroectodermal tumor of the peripheral nervous system. Ganglio-neuromas generally are considered to be benign neoplasms composed of both mature ganglion cells and nerve fascicles with axons, Schwann cells, fibroblasts, and other connective tissue elements [1]. The aim of this study is to clarify the pathomor-phological feature of a subcutaneous ganglio-neuroma which occurred in a Sumatran tiger.
The Utilization of Traditional Conservation of Sumatran Tiger as a Potential Development of Biology Teaching Materials
No full textIndigenous communities have long had an unwritten norm system that regulates the protection of forests and biodiversity inside. The principle of traditional conservation on the island of Sumatra for the preservation of Sumatran tigers is to implement environmental management in the form of prohibitions or invitations in forest areas. On the other hand, this cultural concept is intertwined with learning. Students can discuss lesson concepts in a cultural perspective to support meaningful learning in biology lessons. Therefore, the purpose of this study is to find out the values of traditional conservation of the Sumatran tiger which can be used as a source of developing biology teaching materials based on cultural perspective. The method used in this research is a literature review and content analysis. Researchers searched works of literature from multiple data search engines, namely PubMed, Google Scholar, Mendeley, Semantic Scholar and the Publish or Perish. Data is processed and analyzed according to research needs. Based on the results of the study, obtained results regarding the identification of Sumatran tiger, threats, and forms of conservation in the natural habitat of the Sumatran tiger. Based on the Curriculum 2013, the relevance of this study is linked to the biology material on biodiversity in basic competencies 3.2 and 4.2 regarding distribution, threat analysis, and conservation efforts of biodiversity for the grade of 10-th of high school. The material is also included in the learning outcomes of the Merdeka Curriculum phase E for class x regarding understanding and process skills analyzing interactions between ecosystem components and efforts to conserve biodiversity. These material resources can be developed into a module-based on local culture to be studied independently by students
Population genetics and structure of the Sumatran tiger
No full textThe two key determinants of population persistence in fragmented landscapes are
population size and connectivity. Populations with high levels of genetic variation and
large population size are expected to have a lower risk of extinction. Similarly,
populations with high rates of connectivity are expected to persist long-term. For
many elusive landscape species it is difficult to obtain direct estimates of these
parameters, but genetic sampling can offer powerful indirect assessments. Whilst
these techniques have been applied to the study of many wide-ranging carnivores,
this study represents the first example in the Sumatran tiger (Panthera tigris
sumatrae). Extensive field surveys were conducted to collect faecal samples from
several Tiger Conservation Landscapes and protected areas on Sumatra. Samples
were then processed according to optimised protocols to obtain reliable results. In
order to quantify extinction risk I first estimated genetic variation and effective
population size using microsatellite loci. I also determined relative levels of
connectivity using estimates of differentiation (FST), gene flow and genetic clustering.
Results indicate that Sumatran tigers have high levels of genetic variation and that
their effective population size is within the expected range. There is very little
population structure and there is no obvious evidence for barriers to dispersal. The
Batang Hari/Kerinci Seblat ecosystem emerged as a potential source population and
in contrast there was some evidence of isolation affecting the population of Way
Kambas NP in the extreme south of the island. Overall, despite high levels of human
land cover conversion over the past 20-30 years, few genetic changes have been
expressed in the Sumatran tiger. The immediate threat to tigers is not the loss of
genetic diversity, but the rapidly declining area of suitable habitat in which they can
survive
