Abstract. Ihsan M, Mardiastuti A, Masy’ud B, Mulyani YA. 2021. Population status and sustainability of Yellow-crested cockatoo (Cacatua sulphurea sulphurea) on Pasoso Island, Central Sulawesi, Indonesia. Biodiversitas 22: 3277-3283. Yellow-crested cockatoo (Cacatua sulphurea sulphurea) is a sub-species of Cacatua sulphurea which is spread in Sulawesi and several surrounding islands, including on Pasoso Island. This cockatoo population is under tremendous pressure until categorized as critical. So far, there is no comprehensive information about population status and sustainable population size. The objective of this research area was to assess the current status or size of the population, study the size of the sustainable population and study the determinants factor of the Yellow-crested cockatoo population sustainability on Pasoso Island. The result showed that the population of the Yellow-crested cockatoo in Pasoso Island was only 3 individuals, consists of 2 adults as the parent, and 1 young individual. From 5 analyzed scenarios of the minimum sustainable population size, the 4.1 scenario is the best scenario to maintain the sustainability of the Yellow-crested cockatoo population on Pasoso Island, which is a minimum population size of four pairs (8 adult individuals). The determinants of population sustainbility analysis with the minimum sustainable population size (8 individuals or 4 pairs of broodstock) showed that inbreeding and predation as determinant factors. These factors need to be controlled through mating management and predator control by both humans and carnivorous animals.

Penelitian ini bertujuan untuk mengkaji daya saing komoditi kakao di Sulawesi Tengah dan melihat peran pemerintah dalam meningkatkan daya saing komoditi kakao. Data primer berasal dari observasi, wawancara dan kuesioner, sementara data sekunder berasal dari instansi terkait. Metode analisis menggunakan Policy Analysis Matrix (PAM) dan analisis sensitivitas. Penelitian ini menemukan bahwa nilai PCR Kabupaten Parigi Moutong 0,589 dan Kabupaten Sigi 0,396. Sedangkan nilai DRC Kabupaten Parigi Moutong 0,387 dan Kabupaten Sigi 0,319. Hal tersebut mengindikasikan bahwa usahatani komoditi kakao di Sulawesi Tengah memiliki daya saing, namun tidak menguntungkan secara ekonomi karena Sulawesi Tengah menghasilkan biji kakao yang tidak difermentasi akibatnya petani menerima harga rendah. Berdasarkan hasil analisis, pemerintah belum memberikan proteksi terhadap harga biji kakao dalam negeri melalui harga referensi biji kakao sehingga harga biji kakao didaerah penelitian masih tergolong rendah jika dibandingkan dengan harga di pasar internasional. Sementara terhadap input, pemerintah telah memberikan kebijakan subsidi kepada petani, namun implementasinya masih perlu perbaikan terutama terkait penyaluran dan pengelolaan bantuan agar merata. Kajian ini merekomendasikan masih diperlukan kebijakan pemerintah baik terhadap input maupun output untuk meningkatkan produktivitas, menurunkan biaya produksi dan menaikkan harga jual biji kakao, sehingga dapat meningkatkan daya saing biji kakao. The purpose of this study is to assess the competitiveness of cocoa in Central Sulawesi and to investigate the role of government in improving the competitiveness of cocoa. The primary data were generated through observation, interviews and some questionnaires. The secondary data were obtained from the agency or the institution related to the research. This study uses the Policy Analysis Matrix (PAM) and sensitivity analysis. The study found that the PCR value for Parigi Moutong district was 0.589 and Sigi district was 0.396. While, the DRC value for Parigi Moutong district was 0.387 and Sigi district was 0.319. This indicates that cocoa beans farming in Central Sulawesi has competitiveness, but not economically beneficial because Central Sulawesi produces unfermented cocoa beans consequently farmers receive low prices. Based on the results of the government's impact on output analysis, the government did not provide protection for domestic cocoa seed prices through the reference price of cocoa beans, consequently the price of domestic cocoa beans, particularly in the research area, was relatively low compared to the price of cocoa beans at the international market. Seen from the government policy on inputs, the government have provided subsidies to farmers but they need to improve the distribution and management of aid to be evenly distributed. It is necessary to set up good government policy on inputs and outputs in order to increase cocoa seed productivity, decrease production cost and increase the price which simultaneously can improve its competitiveness in the research location.

Acute and chronic skin wounds due to burns, pressure injuries, and trauma represent a substantial challenge to healthcare delivery with particular impacts on geriatric, paraplegic, and quadriplegic demographics worldwide. Nevertheless, the current standard of care relies extensively on preventive measures to mitigate pressure injury, surgical debridement, skin flap procedures, and negative pressure wound vacuum measures. This article highlights the potential of adipose-, blood-, and cellulose-derived products (cells, decellularized matrices and scaffolds, and exosome and secretome factors) as a means to address this unmet medical need. The current status of this research area is evaluated and discussed in the context of promising avenues for future discovery.

Procapra Przewalskii

AbstractIn 2008 Przewalski's gazelle Procapra przewalskii, endemic to the Qinghai–Tibetan Plateau, China, was recategorized from Critically Endangered to Endangered on the IUCN Red List. The species is still, however, threatened, and the human population and accompanying domestic livestock are increasing around Qinghai Lake. Here we provide up-to-date information on the distribution and population size of the species, evaluate its current conservation status and discuss the difficulties of protecting this gazelle species. We used both distance sampling and total counts to survey 16 sites where the species has been reported and found it at 13 of these, occupying a total area of c. 250 km2. Population size estimated from distance sampling (1,635) and total counts (1,544) was similar. About 20% of the gazelles located were in newly discovered areas for the species. The results indicate an overall growth in the population of Przewalski's gazelle since 2003, although some subpopulations have declined or been extirpated. In spite of conservation efforts Przewalski's gazelle is still threatened by habitat degradation and loss, habitat fragmentation, fencing, intensified competition with domestic livestock and predation. Further growth of this gazelle population is constrained by limited habitat availability and human–gazelle conflict. We recommend that management and conservation strategies need to incorporate comprehensive knowledge of the gazelle, long-term monitoring, and captive breeding of injured and orphaned gazelles to form a potential pool of individuals for future reintroductions to the historical range of the species outside the Qinghai Lake basin.

A study of the population status, habitat preference, and activity pattern of nonbreeding flamingos was carried out in Lakes Abijata, Shalla, and Chitu, part of the Great Rift Valley, Ethiopia, from 2011 to 2013. The current population status and habitat preference of flamingos in the area are still poorly known. Likewise, data on diurnal and seasonal activity pattern of the species are scarce and this leads to the misunderstanding of how Flamingos use local wetlands throughout the different seasons. Data regarding population size and activity pattern were gathered during the wet and dry seasons. Point-count method was used to estimate the population size. Behaviors were recorded using scan sampling techniques. A total of 53671 individuals representing two species of flamingo were counted during both wet and dry seasons from the three lakes. There were more flamingos during the dry season than the wet season in Lake Abijata contrary to Lakes Shalla and Chitu during the wet season. Lesser flamingos (Phoeniconaias minor) were the most abundant species comprising 95.39%, while Greater Flamingos (Phoenicopterus roseus) accounted for 4.61% of the total population. Lake Abijata is the major stronghold of Lesser Flamingos in the area. There was significant variation in the mean number of both species during the wet and dry season in the different study sites of the lake, respectively. The species were known to use varied habitats within the lakes. The Lesser Flamingo mainly preferred the shoreline and mudflat areas of the lakes. However, Greater Flamingo on several occasions showed preference to offshore area of the lakes. Seasonal average flock sizes were not similar between the species. There was a strong relationship between time allocated to each activity and time of day. Feeding activity varied among daylight hours and was higher in the evening (76.5%) and late morning (74.56%) and least during midday (54%). Some variations in activity breakdown were observed between time blocks and season. Conservation efforts in the park should include the wild flora and fauna not only of the land but also of the aquatic systems. The information in this study will be very useful for the future management of the species in the area.

Abstract The research paper is aimed to modify the human health impact assessment of Cr in soils. The current article presents the input of several critical parameters for the human health Impact Score (IShum) assessment in soils. The modification of the IShum is derived using geological data (results of neutron activation analysis of soils are used in the IShum calculation; research area is divided using the watersheds) and population size and density. Watersheds reflect the local environmental conditions of the territory unlike the administrative units due to their geological independence. The calculations of the Characterization factor value underestimate the influence of the population size and density on the final result. Default regional values cannot be considered during the assessment of the potential human health impact for the big sparsely inhabited areas. In case of very low population density the result will be overrated and underestimated in the opposite case. The current approach demonstrates the generosity of the geographical separation in the USEtox model. The same approach can be utilized for other geo zones due to the accessibility of this information (area size, population size and density, geological and landscape features).
