Effective Conservation

Plants are the bedrock of life on Earth but are increasingly threatened with extinction. The most cost-effective way of conserving plant diversity is through Protected Areas (PAs). However, the locality, size, and management of PAs are crucial for effectively maintaining diversity and have been criticized as currently inadequate. Using Armenia as our study site and orchids as our study taxa, we sought to (1) identify spatial patterns of orchid diversity hotspots and corresponding PA network sites; (2) examine if the current PA network is effective at capturing orchid species richness and diversity and (3) explore the relationship between the range of area suitability of species and level of protection. We used data collected from herbarium, field visits and GBIF occurrence records. Using freely available mapping software, we created heatmaps of observations and species richness. We compared PA sites based on the number of species (species richness) and diversity (Shannon–Weiner Index). Species range was developed using the MaxEnt model and a correlation analysis was performed against the proportion of the range within PA. We found that 57% of PA sites have a representation of at least one species of orchid, but some threatened species are not presented within any PA site. The Tavush and Syunik province not only held the highest species richness (>10 species), but the PA network within also held high orchid diversity (2.5 diversity index value for Dilijan National Park). We did not find a significant relationship between the range of area suitability for orchids and protection; however, all our target species had less than 30% of their range under protection. Our study highlights important challenges related to the limitations of available data, and we discuss these implications towards effective conservation outcomes for orchids for the region.

Abstract: The objective of this work was to analyze the spatial distribution and the behavior of species richness and diversity in a shrub savanna fragment, in 2003 and 2014, using ordinary kriging, in the state of Minas Gerais, Brazil. In both evaluation years, the measurements were performed in a fragment with 236.85 hectares, in which individual trees were measured and identified across 40 plots (1,000 m2). Species richness was determined by the total number of species in each plot, and diversity by the Shannon diversity index. For the variogram study, spatial models were fitted and selected. Then, ordinary kriging was applied and the spatial distribution of the assessed variables was described. A strong spatial dependence was observed between species richness and diversity by the Shannon diversity index (<25% spatial dependence degree). Areas of low and high species diversity and richness were found in the shrub savanna fragment. Spatial distribution behavior shows relative stability regarding the number of species and the Shannon diversity index in the evaluated years.

A comprehensive inventory of faunal biodiversity was conducted within three Key Biodiversity Areas of Central Visayas. Mt. Bandilaan Natural Park (MBNP), Balinsasayao Twin Lakes Natural Park (BTLNP), and Rajah Sikatuna Protected Landscape (RSPL). Three primary wildlife groups were surveyed: bats, birds and amphibians. Species diversity and population trends were then analyzed to assess areas of biodiversity importance. RSPL generally had the highest species richness and diversity index while MBNP consistently had the lowest. When pooled. The surveyed areas resulted in a high diversity index and rate of endemicity showing the importance of multiple areas of protection. These findings can be utilized to prioritize habitat protection as well as to serve as a baseline information for future biodiversity inventories. J. Biodivers. Conserv. Bioresour.

Cultivation Practice

Indonesia memiliki luasan hutan hujan tropis terluas nomor tiga setelah Brazil dan Afrika. Namun, tingkat degradasi hutan yang tinggi di Indonesia menyebabkan negara ini menjadi salah satu penyumbang emisi gas rumah kaca terbesar di dunia. Salah satu penyebab turunnya luasan hutan tropis di Indonesia adalah praktek perladangan berpindah. Suksesi vegetasi pasca perladangan berpindah dapat memberikan layanan ekologis berupa peningkatan tutupan vegetasi dan perbaikan sifat tanah yang jarang sekali terekspose pada tingkat lanjut. Penelitian ini bertujuan untuk mengetahui dinamika suksesi vegetasi padalahan pasca perladangan berpindah tingkat lanjut. Penelitian dinamika suksesi vegetasi dilakukan dengan pengambilan sampel tanaman bawah, semai sapihan dan pohon di lahan pasca perladangan dengan tiga umur yang berbeda, yaitu bera muda (1 – 10 tahun), bera sedang (11 – 20 tahun), bera tua (> 20 tahun), dan hutan alam dengan menggunakan metode petak bersarang dengan plot yang ditempatkan secara sistematik. Analisis vegetasi dengan menggunakan Indeks Nilai Penting, Kelimpahan Jenis, Keragaman, dan Kemerataan. Analisis varian dengan uji lanjut DMRT digunakan jika hasil dari tiap index vegetasi berbeda signifikan antar umur perladangan. Adanya pola peningkatan serta perbedaan yang nyata (P < 0,05) antara kelimpahan dan keragaman jenis vegetasi penyusun lahan bera sedang dengan lahan bera tua pada tingkatan pohon kecuali vegetasi penyusun tanaman bawah. Nilai keragaman dan kelimpahan jenis tingkat pohon lahan bera tua tidak berbeda nyata dengan hutan alam namun memiliki komposisi yang berbeda.The Dynamics of Succession of Vegetation in the Post-Shifting Cultivation Area in Central KalimantanAbstractIndonesia’s forests is the third largest tropical forest after Brazil and Africa. However, the high rate of forest degradation in Indonesia led this country become one of the most largest contributor of greenhouse gas emissions in the world. One of the causes of the degradation of tropical forest in Indonesia is the shifting cultivation practice. The succession of vegetation after shifting cultivation practice can provide ecological services such as increasing vegetation cover and improving soil properties but takes too long to recover. This study aims to understand the dynamics of vegetation succession in the post-shifting cultivation advanced stage. This study was conducted using systematical nested sampling method to take sample of shurb and herbs, and trees, including, seedling and, sapling growth stage form three different stage of post-shifting cultivation land areas, ie young fallow (1 - 10 years), intermediate fallow (11 - 20 years), old fallow (> 20 years), and natural forest. The vegetation data were then analyzed using Important Value, Species Richness, Diversity and Evenness Indices. Analysis of variance with post-hoc test of DMRT assays was used if the results each vegetation indices differed significantly between stage of post-shifting cultivation land. The Species Richness and Diversity Index of shurb and herb, seedling, sapling, and tree have significantly increased (P < 0,05) except the herb and shrub communities. The Species richness and Diversity Index of tree stage of old fallow were not significantly different from natural forest but it was composed with different species.

Abstract. Yudaputra A, Rahardjo P. 2020. Short Communication: Plant species richness and diversity in Karangsambung-Karangbolong National Geopark, Indonesia. Biodiversitas 21: 1735-1742. The information on plant species richness and diversity in Karangsambung-Karangbolong National Geopark, Central Java is very limited. This study aimed: (1) to investigate plant species richness and abundance as well as floristic composition in Karangsambung-Karangbolong National Geopark; (2) to reveal the potential uses of plant species recorded in the area. Square sampling plots were applied for nine sampling locations. Square plot of 10 x 10 m was applied to record tree, while nested plots of 5 x 5 m and 2 x 2 m were applied to record sapling and understorey plants including shrubs and herbs, respectively. The highest plant species richness was found in the location with higher elevation and mountainous topography. The species abundance reaches its maximum values at low to moderate elevation. Shannon Diversity Index (H) showed that tree and sapling have moderate diversity, whereas understorey plant has high diversity. Melastoma malabathricum, Clidemia hirta, Zingiber zerumbet, and Ageratum conyzoides are the most abundant plants in this Geopark. Most of plants recorded have potential benefit as medicinal uses.

Abstract The primary objective of this study was to investigate the seasonal fish and crustacean variations concerning taxonomic composition, species richness, and diversity in sandy beach habitat. For this purpose, we investigated the Sonmiani Hor lagoon area during four distinct seasons, i.e., northeast (NE) monsoon, pre-monsoon, south-west (SW) monsoon, and post-monsoon for one year. During each haul, the net was pulled about 100m along the beach in 0.5m depth. The results showed a strong linear correlation between the diversity index and equitability in fishes (r = 0.978). The diversity index was strong negatively correlated with the abundance and biomass (r = -0.978, -0.972, respectively). The physical attributes like sea surface water temperature and salinity showed a strong negative effect on species assemblages (r = -0.981 and -0.943, respectively). The mean air and water temperature illustrated approximately 3°C difference during NE and pre-monsoon seasons. However, salinity, pH, and electrical conductivity did not show any significant seasonal variabilities. Under the ecological indices, the fish species displayed higher diversity (H’ = 3.19) during SW monsoon, whereas the lowest diversity was observed during pre-monsoon (H’ = 1.58). The equitability and species richness, however, remained more noticeable during SW monsoon (J’ = 0.81). The total number of individuals of fish and crustaceans reached 4799 with 3813 fish individuals and 986 individuals of crustaceans. A total of 27 families of fish while five crustacean families comprising of 30 genera and 38 fish species while ten genera and 17 species of crustaceans were recorded. Liza subviridis displayed the highest abundance among the sampled fish species. In conclusion, fish species constituted a significant part of the coastal fauna in the study area. The seasonal variations displayed distinct variations in fish species composition and diversity.

Malaise Traps

A study on abundance and diversity of Hymenoptera was conducted in Gunung Datuk, Rembau. Samplings were conducted from November 2014 to February 2015 using six Malaise traps. Three traps were placed at Site 1 at 700m height for high elevation and the remaining traps were placed at Site 2 at 200m height for low elevation. A total number of 221 Hymenopteran were collected which consist of nine families namely Ichneumonidae, Formicidae, Braconidae, Bethylidae, Evaniidae, Tiphiidae, Vespidae, Pompilidae and Apidae. In this study, 93 individuals were obtained from Site 1, comprising nine families and 43 morphospecies while 127 individuals were obtained from Site 2 with nine families and 45 morphospecies. Formicidae was the most dominant family collected from both sites with a total of 104 individuals while the least family recorded was Apidae with only one individual. Shannon’s Weiner Diversity Index (H’) showed Site 1 had the higher diversity value with H’ = 3.17 compared to Site 2 with value H’ = 3.12. For Evenness Index, Site 1 had higher value compared to Site 2 with E’ = 0.84 and E’ = 0.82 respectively. Moreover, for Margalef Richness Index, Site 1 recorded R’ = 9.24 while site two recorded R’ = 9.08 which concluded that Site 1 had higher species richness compared to Site 2. Paired t-test showed that both sites had no significant difference with p>0.05. Overall study showed that the diversity and abundance of Hymenoptera in Gunung Datuk were low since the value of H’ is less than 3.50.

This paper is concerned with the socio-spatial and ethical politics of redistribution, specifically the allocation of natural resources rents from political and economic cores to the economic and geographical peripheries whence the resource originated. Based on a case study of the coal seam gas sector in Queensland's Surat Basin, this paper focuses on the operation of the Queensland State Government's regional development fund for mining and energy extraction-affected regions. Employing an environmental justice framework, we critically explore the operation of these funds in ostensibly helping constituent communities in becoming resilient to the worst effects of the ‘staples trap’. Drawing on secondary demographic and housing data for the region, as well as primary information collected from key respondents from mid-2018 to early 2019, we show that funds were distributed across all of the local government areas, and allocated to projects and places primarily on a perceived economic needs basis. However, concerns were raised with the probity of the funds’ administration. In terms of recognition justice, the participation of smaller and more remote towns and local Indigenous communities was hampered by their structural marginalisation. Procedurally, the funds were criticised for the lack of local consultation taken in the development and approval of projects. While spatially concentrated expenditure may be the most cost-effective use of public monies, we argue that grant application processes should be open, transparent and inclusive, and the outcomes cognisant of the developmental needs of smaller communities, together with the need to foster regional solidarity and coherence.
