Abstract | Links | BibTeX | Tags: Cockatoo, conservation, Harvesting, Protection, Trade @article{Haryoko2021, Birds are among the most favored pet animals and are nurtured because of their melodious voice, intelligence, and beautiful feathers. Therefore, these animals are usually traded in both local and international markets. Wild bird trades are dominated by species from the order Passeriformes/songbirds and Psittaciformes/parrots. Furthermore, one of the Psittaciformes groups that are in high demand as a pet is the cockatoos. The Goffin's cockatoo or Tanimbar corella/Cacatua goffiniana (Finsch, 1863)is one of seven species of parrots native to Indonesia and has been traded for decades. This endemic bird from the Tanimbar Islands (Maluku) has been protected by the Indonesian government since 1990 and has been on the CITES Appendix I since 1992. Therefore, this study aims to review the harvesting of C. goffiniana and the effect the bird's protection status has on its trade. It was conducted by investigating the legal trade data for 1981-2018, information on illegal trade, and ex-situ conservation of this species. The review on the trade of C. goffiniana was assessed using descriptive analysis. Furthermore, Independent Samples T-Test was used to determine the differences between the number of C. goffiniana traded before and after the bird was listed in Appendix I CITES and protected by Indonesia's law. The results showed that the number of exported Cacatua goffiniana for 38 years to 34 countries was 151,684. Furthermore, the United States of America was the largest importer with a total of 118,356/78.03%. It was discovered that the number of birds legally exported by Indonesia has decreased dramatically since 1990 because these animals are protected by Indonesian law. Consequently, there was a significant difference between the number traded before and after their designation as protected species. The nonparametric correlation between protection status and Appendix I CITES listing to the number of these animals traded was statistically significant. Finally, existing conservation practices involve efforts to restock the population by means of captive breeding programs. However, as conservation agencies have shown little success in breeding these species, the efforts are not sufficient to fulfill the demand. Therefore, illegal trade is still a major threat to the natural populations. |

September, pp. 1–9, 2021, ISSN: 2296665X. Abstract | Links | BibTeX | Tags: biodiversity, climate change, conservation, mammal, tropical landscape @article{Condro2021a, The Leuser Ecosystem is one of the essential landscapes in the world for biodiversity conservation and ecosystem services. However, the Leuser Ecosystem has suffered many threats from anthropogenic activities and changing climate. Climate change is the greatest challenge to global biodiversity conservation. Efforts should be made to elaborate climatic change metrics toward biological conservation practices. Herein, we present several climate change metrics to support conservation management toward mammal species in the Leuser Ecosystem. We used a 30-year climate of mean annual temperature, annual precipitation, and the BIOCLIM data to capture the current climatic conditions. For the future climate (2050), we retrieved three downscaled general circulation models for the business-as-usual scenario of shared socioeconomic pathways (SSP585). We calculated the dissimilarities of the current and 2050 climatic conditions using the standardized Euclidean distance (SED). To capture the probability of climate extremes in each period (i.e., current and future conditions), we calculated the 5th and 95th percentiles of the distributions of monthly temperature and precipitation, respectively, in the current and future conditions. Furthermore, we calculated forward and backward climate velocities based on the mean annual temperature. These metrics can be useful inferences about species conservation. Our results indicate that almost all of the endangered mammals in the Leuser Ecosystem will occur in the area with threats to local populations and sites. Different conservation strategies should be performed in the areas likely to present different threats toward mammal species. Habitat restoration and long-term population monitoring are needed to support conservation in this mega biodiversity region. |

Repi, Terri; Masy'ud, Burhanuddin; Mustari, Abdul Haris; Prasetyo, Lilik B Population density, geographical distribution and habitat of Talaud bear cuscus (Ailurops melanotis Thomas, 1898) Journal Article In: Biodiversitas, vol. 21, no. 12, pp. 5621-5631, 2020. Abstract | Links | BibTeX | Tags: Ailurops melanotis, conservation, density, distribution, habitat, population @article{Repi2020, The Talaud bear cuscus (Ailurops melanotis) has been reported from Sangihe (the largest island in the Sangihe Island group) and Salibabu (within the Talaud Islands). As an endemic species of Indonesia, this species is rare and there is no certainty regarding its precise geographic distribution or population size. This research aimed to estimate population density and provide the first preliminary data on its geographical distribution, as well as general description of its habitat. Our research shows that A. melanotis occurs on three islands: Salibabu Island, Nusa Island, and Bukide Island, and probably also exists in the Sahandaruman mountain on Sangihe Island. Our population surveys estimate, population density on each island as: Salibabu: 3.69 ± 2.54 ind/km2, with an estimated total population of 28.95 individuals, Nusa Island: was 12.31 ± 2.58 ind/km2, with an estimated population of 19.08 individuals, and Bukide Island: 7.17 ± 1.79/km2, with an estimated population of 10.40 individuals. Information regarding population is a key guiding factor in conservation efforts, where population size is related to extinction risk (threat status) and its geographical distribution, this can help to determine conservation priorities for species or habitats. |
