AbstractThe illegal wildlife trade is driving declines in populations of a number of large, charismatic animal species but also many lesser known and restricted-range species, some of which are now facing extinction as a result. The ploughshare tortoise Astrochelys yniphora, endemic to the Baly Bay National Park of north-western Madagascar, is affected by poaching for the international illegal pet trade. To quantify this, we estimated population trends during 2006–2015, using distance sampling surveys along line transects, and recorded national and international confiscations of trafficked tortoises for 2002–2016. The results suggest the ploughshare tortoise population declined > 50% during this period, to c. 500 adults and subadults in 2014–2015. Prior to 2006 very few tortoises were seized either in Madagascar or internationally but confiscations increased sharply from 2010. Since 2015 poaching has intensified, with field reports suggesting that two of the four subpopulations are extinct, leaving an unknown but almost certainly perilously low number of adult tortoises in the wild. This study has produced the first reliable population estimate of the ploughshare tortoise and shows that the species has declined rapidly because of poaching for the international pet trade. There is an urgent need for increased action both in Madagascar and along international trade routes if the extinction of the ploughshare tortoise in the wild is to be prevented.

Abstract. Susilowati A, Rachmat HH, Elfiati D, Kholibrina CR, Kusuma YS, Siregar H. 2019. Population structure of Cotylelobium melanoxylon within vegetation community in Bona Lumban Forest, Central Tapanuli, North Sumatra, Indonesia. Biodiversitas 20: 1681-1687. In many forests stand, Cotylelobium melanoxylon is hard to find in the wild at present day because its bark has been intensively harvested for traditional alcoholic drink and sold by kilogram in traditional market in North Sumatra and Riau. This activity has put the species into serious threats of their existence in their natural habitat. We conducted study to determine the population structure of the species at seedling to tree stage in Bona Lumban Forest, Central Tapanuli. We used purposive sampling by making line transect at forest area where C. melanoxylon naturally grow. There were four transects with each transect consisted of five plots in which nested plots were established to record data at four growth stages, resulting in 80 plots in total. The result showed that the Important Value Index (IVI) for C. melanoxylon were 66.33, 17.65, 11.82, 12.90; Diversity Index (H) were 2.9, 1.90,2.88, 2.53 and 12.90, Index of evenness (E) were 0.844, 0.534, 0.85, 0.935 and the Index of Richness (R) were 5.71, 7.13, 5.37, 3.67 for the stage tree, pole, sapling, and seedlings, respectively This result demonstrates that C. melanoxylon still grows naturally in Bona Lumban at all stages from tree to seedling. However, there might be a problem in its natural regeneration as there is big difference of its high IVI at tree stage compared to IVI value for its younger stages. The regeneration status of C. melanoxylon was also classified into fair. This might be generated from the condition that the existing mature trees remaining were no longer productive and healthy due to excessive harvesting for its bark.

Indonesia has been identified as the highest priority country for parrot conservation based on the number of species, endemics, and threats (trapping and smuggling). It is crucial to understand the current population status of parrots in the wild in relation to the illegal wildlife trade but the ecology and population dynamics of most parrot species in this region remain poorly understood. We conducted a parrot survey around an area of high biodiversity in the Manusela National Park, in Seram Island, Indonesia. We used a combination of fixed-radius point counts and fixed-width line transects to count multiple species of parrots. We recorded nearly 530 wild parrots from 10 species in and around Manusela National Park. The dominant parrot species were Eos bornea, Trichoglosus haematodus, and Geoffroyus geoffroyi. We applied the Savage selectivity index to evaluate poaching of parrot species in proportion to their abundance and which species had higher than expected poaching pressure. This study has important implications for the conservation status of endemic parrots (Cacatua moluccensis, Lorius domicella, and Eos semilarvata) and shows that parrots in the Manusela NP are largely threatened by poaching.

Abstract This study aims to identify the structure, composition, and current status of highland peat vegetation in the Lintong Nihuta Sub-district, Humbang Hasundutan Regency, North Sumatra Province. The research conducted from December 2020 to April 2021. This study uses a survey method. The plots were laid using the purposive sampling method considering that the observed plots were those with naturally growing vegetation and accessible terrain. Sampling used the double plot vegetation analysis method with a plot size of 4 x 4 m for seedlings and 20 x 20 m for saplings obtained by measuring the minimum area of the plot. The data obtained were analyzed for frequency calculations, important value index (IVI), and Shannon-Weiner diversity index (H’). The results of the vegetation analysis showed that from the four existing growth classes, only two growth classes were found at the research site, namely seedlings and saplings with a total of 23 species. The vegetation composition is dominated by shrub habitus which indicates that this peatland has been degraded. The dominant species in the study site were Lepinoria mucronata Rich. and Dicranopteris linearis (Burm.) F. Underw. The value of the biodiversity index (H’) is 0.8 with a low criterion which means the vegetation ecosystem at the study site is unstable

Unique Species

The Indian Pangolin Manis crassicaudata, is an ‘Endangered’ mammal species native to Pakistan but facing a risk of extinction due to hunting pressure for its scales used in trade.  The current study investigated habitat preference of this unique species in the Margalla Hills National Park, Islamabad, from September 2011 to August 2012.  Three habitat types, viz, human vicinity area, agricultural land, and wild/natural area, were searched for recording signs of Indian Pangolin.  Data on habitat preference was collected from direct and indirect signs of the species by monitoring 85 line transects, each measuring 500m in length and 50m in width, in 17 different sampling sites.  A total of 323 signs of Indian Pangolin were recorded including 299 burrows, 10 live sightings, and 14 scats of the species.  The maximum number of signs were recorded in wild or unmodified natural area (55.1%), followed by those in vicinity to human use area (20.12%), while the least (24.76%) were found in agricultural area.  Statistical comparison using one-way analysis of variance of pangolin field signs, among three different types of habitats studied, differed significantly (df= 48, F= 13.723, p <0.001).  Similarly, LSD analysis further revealed that field signs of Indian pangolin recorded on natural or wild habitat significantly differed from those which were on agricultural land and human vicinity area (p <0.001).  The study concludes that the Indian Pangolin prefers habitats in the wild or natural area over those close to human vicinity and agricultural lands.

Lullabies are essentially sung for their soothing nature but, as this article shows, they have other important functions. One of the most important of these is that lullabies may provide much-needed language stimulation with important long-term consequences for future learning. This paper begins the work of addressing the dearth of scholarly research on lullabies, especially in the Yoruba (Nigeria: Niger-Congo) culture. It looks at the range of themes, dictions, and prosody that are intertwined to reveal Yoruba beliefs and world-views about children, starting with their time in the womb. The study uses a descriptive survey method to analyse data collected through participant observation. It shows that Yoruba lullabies not only offer insights into Yoruba cultural beliefs but also depend greatly on figurative expression and prosodic systems. These rich literary qualities identify lullabies as the earliest sub-genre of children's poetry.

Essential Contribution

Way Kambas National Park (WKNP) is home of five protected big mammals including sumatran elephants.  It shares its border with 22 of 37 villages surrounding the national park.  Understanding their existence in the wild is a priority, and  wildlife genetics is a crucially needed. Besides poaching and habitat fragmentation, wildlife-human conflict is one big issue.  Elephant Training Center (ETC) in WKNP is built for semi in-situ conservation effort on captive sumatran elephants that mainly have conflict histories with local people.  Participative observation and bio-molecular analysis were conducted to learn the importance of captive Sumatran elephant for conservation effort.  Through captive sumatran elephants, database and applicable methods are expected to be developed supporting the conservation of their population in the wild.  Participative observation and molecular identification was carried on captive sumatran elephants in ETC, WKNP under multiple year Terapan grant of Ministry of Research and Technology Higher Education, Indonesia. Gene sequence and cytological analyses showed that the captive sumatran elephants are closely related and tend to be domesticated.  Translocation among ETC to avoid inbreeding, and maintaining the captive sumatran elephant as natural as possible are highly recommended. Developing genetic database can be a reference for both captive and wild sumatran elephants.
