    Hadi UK, Takaoka H
    Acta Trop, 2018 Sep;185:133-137.
    PMID: 29452114 DOI: 10.1016/j.actatropica.2018.02.013
    Indonesia is one of the megadiversity country in the world endowed with rich and unique biodiversity insects such as blackflies species (Diptera: Simuliidae). Blackflies are found almost anywhere with running water suitable as habitat for the immature stages. This family is one of the most important groups of blood-sucking insects. This study collates the records of Simulium (Diptera: Simuliidae) in previous publications related fauna of Indonesia. Based on the results of this study, there were 124 species of blackflies in Indonesian Archipelago. All species are assigned to the genus Simulium Latreille s.l., and are placed into five subgenera, i.e. Gomphostilbia Enderlein, Morops Enderlein, Nevermannia Enderlein, Simulium Latreille s.str. and Wallacellum Takaoka. Further classification into 27 species groups within the subgenera were also made. Checklists of Indonesian Simuliidae are provided including data on the distribution of each species.

  3. Long term flow change threatens invertebrate diversity in temporary streams: Evidence from an island
    Garcia C, Gibbins CN, Pardo I, Batalla RJ
    Sci Total Environ, 2017 Feb 15;580:1453-1459.
    PMID: 28027801 DOI: 10.1016/j.scitotenv.2016.12.119
    Here we provide the first evidence of long term reductions in flow in temporary streams on the Mediterranean island of Mallorca and use a simple metric of the degree of water permanence (the number of days with water) to highlight the implications of flow change for aquatic invertebrate diversity. Analysis of a 33year data set for 13 streams on the island yielded evidence of consistent downward trends in water permanence, particularly in spring and summer. Data from 27 relatively undisturbed mountain streams indicate that the diversity of benthic invertebrates in temporary streams across the island is directly related to water permanence. Streams with lower values of water permanence support few species overall and have less abundant invertebrate assemblages; the abundance and species richness of sensitive mayfly, stonefly and caddisfly taxonomic groups is also reduced in streams with lower water permanence. Although developed using spatial data, these flow-invertebrate relationships suggest that future reductions in water permanence may lead to reduced diversity. We argue that the 'number of days with water' is a simple but ecologically-relevant metric of water permanence that can be used effectively to monitor change in threatened temporary streams worldwide.

  4. Fulltext Arbuscular mycorrhizal trees influence the latitudinal beta-diversity gradient of tree communities in forests worldwide
    Zhong Y, Chu C, Myers JA, Gilbert GS, Lutz JA, Stillhard J, et al.
    Nat Commun, 2021 May 25;12(1):3137.
    PMID: 34035260 DOI: 10.1038/s41467-021-23236-3
    Arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) associations are critical for host-tree performance. However, how mycorrhizal associations correlate with the latitudinal tree beta-diversity remains untested. Using a global dataset of 45 forest plots representing 2,804,270 trees across 3840 species, we test how AM and EcM trees contribute to total beta-diversity and its components (turnover and nestedness) of all trees. We find AM rather than EcM trees predominantly contribute to decreasing total beta-diversity and turnover and increasing nestedness with increasing latitude, probably because wide distributions of EcM trees do not generate strong compositional differences among localities. Environmental variables, especially temperature and precipitation, are strongly correlated with beta-diversity patterns for both AM trees and all trees rather than EcM trees. Results support our hypotheses that latitudinal beta-diversity patterns and environmental effects on these patterns are highly dependent on mycorrhizal types. Our findings highlight the importance of AM-dominated forests for conserving global forest biodiversity.

  5. Impact of climate change on biodiversity loss: global evidence
    Habibullah MS, Din BH, Tan SH, Zahid H
    Environ Sci Pollut Res Int, 2022 Jan;29(1):1073-1086.
    PMID: 34341937 DOI: 10.1007/s11356-021-15702-8
    The present study investigates the impact of climate change on biodiversity loss using global data consisting of 115 countries. In this study, we measure biodiversity loss using data on the total number of threatened species of amphibians, birds, fishes, mammals, mollusks, plants, and reptiles. The data were compiled from the Red List published by the International Union for Conservation of Nature (IUCN). For climate change variables, we have included temperature, precipitation, and the number of natural disaster occurrences. As for the control variable, we have considered governance indicator and the level of economic development. By employing ordinary least square with robust standard error and robust regression (M-estimation), our results suggest that all three climate change variables - temperature, precipitation, and the number of natural disasters occurrences - increase biodiversity loss. Higher economic development also impacted biodiversity loss positively. On the other hand, good governance such as the control of corruption, regulatory quality, and rule of law reduces biodiversity loss. Thus, practicing good governance, promoting conservation of the environment, and the control of greenhouse gasses would able to mitigate biodiversity loss.

  6. Fulltext Diversity of isoprene-degrading bacteria in phyllosphere and soil communities from a high isoprene-emitting environment: a Malaysian oil palm plantation
    Carrión O, Gibson L, Elias DMO, McNamara NP, van Alen TA, Op den Camp HJM, et al.
    Microbiome, 2020 06 03;8(1):81.
    PMID: 32493439 DOI: 10.1186/s40168-020-00860-7
    BACKGROUND: Isoprene is the most abundantly produced biogenic volatile organic compound (BVOC) on Earth, with annual global emissions almost equal to those of methane. Despite its importance in atmospheric chemistry and climate, little is known about the biological degradation of isoprene in the environment. The largest source of isoprene is terrestrial plants, and oil palms, the cultivation of which is expanding rapidly, are among the highest isoprene-producing trees.

    RESULTS: DNA stable isotope probing (DNA-SIP) to study the microbial isoprene-degrading community associated with oil palm trees revealed novel genera of isoprene-utilising bacteria including Novosphingobium, Pelomonas, Rhodoblastus, Sphingomonas and Zoogloea in both oil palm soils and on leaves. Amplicon sequencing of isoA genes, which encode the α-subunit of the isoprene monooxygenase (IsoMO), a key enzyme in isoprene metabolism, confirmed that oil palm trees harbour a novel diversity of isoA sequences. In addition, metagenome-assembled genomes (MAGs) were reconstructed from oil palm soil and leaf metagenomes and putative isoprene degradation genes were identified. Analysis of unenriched metagenomes showed that isoA-containing bacteria are more abundant in soils than in the oil palm phyllosphere.

    CONCLUSION: This study greatly expands the known diversity of bacteria that can metabolise isoprene and contributes to a better understanding of the biological degradation of this important but neglected climate-active gas. Video abstract.

  7. The value of biodiversity for the functioning of tropical forests: insurance effects during the first decade of the Sabah biodiversity experiment
    Tuck SL, O'Brien MJ, Philipson CD, Saner P, Tanadini M, Dzulkifli D, et al.
    Proc Biol Sci, 2016 Dec 14;283(1844).
    PMID: 27928046
    One of the main environmental threats in the tropics is selective logging, which has degraded large areas of forest. In southeast Asia, enrichment planting with seedlings of the dominant group of dipterocarp tree species aims to accelerate restoration of forest structure and functioning. The role of tree diversity in forest restoration is still unclear, but the 'insurance hypothesis' predicts that in temporally and spatially varying environments planting mixtures may stabilize functioning owing to differences in species traits and ecologies. To test for potential insurance effects, we analyse the patterns of seedling mortality and growth in monoculture and mixture plots over the first decade of the Sabah biodiversity experiment. Our results reveal the species differences required for potential insurance effects including a trade-off in which species with denser wood have lower growth rates but higher survival. This trade-off was consistent over time during the first decade, but growth and mortality varied spatially across our 500 ha experiment with species responding to changing conditions in different ways. Overall, average survival rates were extreme in monocultures than mixtures consistent with a potential insurance effect in which monocultures of poorly surviving species risk recruitment failure, whereas monocultures of species with high survival have rates of self-thinning that are potentially wasteful when seedling stocks are limited. Longer-term monitoring as species interactions strengthen will be needed to more comprehensively test to what degree mixtures of species spread risk and use limited seedling stocks more efficiently to increase diversity and restore ecosystem structure and functioning.

  8. Habitat change and biodiversity loss in South and Southeast Asian countries
    Tan YL, Chen JE, Yiew TH, Habibullah MS
    Environ Sci Pollut Res Int, 2022 Sep;29(42):63260-63276.
    PMID: 35459997 DOI: 10.1007/s11356-022-20054-y
    South and Southeast Asia is by far the most populous region in Asia, with the greatest number of threatened species. Changes in habitat are a major contributor to biodiversity loss and are more common as a result of land-use changes. As a result, the goal of this study is to use negative binomial regression models to investigate habitat change as one of the important drivers of biodiversity loss in South and Southeast Asian countries from 2013 to 2018. According to the negative binomial estimates, the findings for the habitat change measures are quantitatively similar for the impacts of agricultural land and arable land on biodiversity threats. Agricultural and arable land both have a positive impact on biodiversity loss. We found that, contrary to our expectations, the forest area appears to have an unexpected direct influence on the number of threatened species. A higher number of threatened species is associated with rising per capita income, human population and a low level of corruption control. Finally, the empirical findings are consistent across taxonomic groups, habitat change measures and Poisson-based specifications. Some policy implications that could mitigate biodiversity loss include educating and promoting good governance among the population and increase the conservation effort to sustain green area and national forest parks in each country.

  10. Fulltext Estimating biodiversity impacts without field surveys: A case study in northern Borneo
    Kitzes J, Shirley R
    Ambio, 2016 Feb;45(1):110-9.
    PMID: 26169084 DOI: 10.1007/s13280-015-0683-3
    In many regions of the world, biodiversity surveys are not routinely conducted prior to activities that lead to land conversion, such as development projects. Here we use top-down methods based on global range maps and bottom-up methods based on macroecological scaling laws to illuminate the otherwise hidden biodiversity impacts of three large hydroelectric dams in the state of Sarawak in northern Borneo. Our retrospective impact assessment finds that the three reservoirs inundate habitat for 331 species of birds (3 million individuals) and 164 species of mammals (110 million individuals). A minimum of 2100 species of trees (900 million individuals) and 17 700 species of arthropods (34 billion individuals) are estimated to be affected by the dams. No extinctions of bird, mammal, or tree species are expected due to habitat loss following reservoir inundation, while 4-7 arthropod species extinctions are predicted. These assessment methods are applicable to any data-limited system undergoing land-use change.

  11. Fulltext Landscape-level human disturbance results in loss and contraction of mammalian populations in tropical forests
    Greco I, Beaudrot L, Sutherland C, Tenan S, Hsieh C, Gorczynski D, et al.
    PLoS Biol, 2025 Feb;23(2):e3002976.
    PMID: 39946310 DOI: 10.1371/journal.pbio.3002976
    Tropical forests hold most of Earth's biodiversity and a higher concentration of threatened mammals than other biomes. As a result, some mammal species persist almost exclusively in protected areas, often within extensively transformed and heavily populated landscapes. Other species depend on remaining remote forested areas with sparse human populations. However, it remains unclear how mammalian communities in tropical forests respond to anthropogenic pressures in the broader landscape in which they are embedded. As governments commit to increasing the extent of global protected areas to prevent further biodiversity loss, identifying the landscape-level conditions supporting wildlife has become essential. Here, we assessed the relationship between mammal communities and anthropogenic threats in the broader landscape. We simultaneously modeled species richness and community occupancy as complementary metrics of community structure, using a state-of-the-art community model parameterized with a standardized pan-tropical data set of 239 mammal species from 37 forests across 3 continents. Forest loss and fragmentation within a 50-km buffer were associated with reduced occupancy in monitored communities, while species richness was unaffected by them. In contrast, landscape-scale human density was associated with reduced mammal richness but not occupancy, suggesting that sensitive species have been extirpated, while remaining taxa are relatively unaffected. Taken together, these results provide evidence of extinction filtering within tropical forests triggered by anthropogenic pressure occurring in the broader landscape. Therefore, existing and new reserves may not achieve the desired biodiversity outcomes without concurrent investment in addressing landscape-scale threats.

  12. Fulltext A DNA barcode reference of Asian ferns with expert-identified voucher specimens and DNA samples
    Kuo LY, Tang SK, Huang YH, Xie PJ, Chen CW, Chang ZX, et al.
    Sci Data, 2024 Dec 02;11(1):1314.
    PMID: 39622837 DOI: 10.1038/s41597-024-04161-8
    Ferns belong to species-rich group of land plants, encompassing more than 11,000 extant species, and are crucial for reflecting terrestrial ecosystem changes. However, our understanding of their biodiversity hotspots, particularly in Southeast Asia, remains limited due to scarce genetic data. Despite harboring around one-third of the world's fern species, less than 6% of Southeast Asian ferns have been DNA-sequenced. In this study, we addressed this gap by sequencing 1,496 voucher-referenced and expert-identified fern samples from (sub)tropical Asia, spanning Malaysia, the Philippines, Taiwan, and Vietnam, to retrieve their rbcL and trnL-F sequences. This DNA barcode collection of Asian ferns encompasses 956 species across 152 genera and 34 families, filling major gaps in fern biodiversity understanding and advancing research in systematics, phylogenetics, ecology and conservation. This dataset significantly expands the Fern Tree of Life to over 6,000 species, serving as a pivotal and global reference for worldwide barcoding identification of ferns.

  13. Island geography drives evolution of rattan palms in tropical Asian rainforests
    Kuhnhäuser BG, Bates CD, Dransfield J, Geri C, Henderson A, Julia S, et al.
    Science, 2025 Mar 14;387(6739):1204-1209.
    PMID: 40080567 DOI: 10.1126/science.adp3437
    Distributed across two continents and thousands of islands, the Asian tropics are among the most species-rich areas on Earth. The origins of this diversity, however, remain poorly understood. Here, we reveal and classify contributions of individual tropical Asian regions to their overall diversity by leveraging species-level phylogenomic data and new fossils from the most species-rich Asian palm lineage, the rattans and relatives (Arecaceae, Calamoideae). Radiators (Borneo) generate and distribute diversity, incubators (Indochina, New Guinea, and Sulawesi) produce diversity in isolation, corridors (Java, Maluku, Sumatra, and the Thai-Malay Peninsula) connect neighboring regions, and accumulators (Australia, India, Palawan, and the Philippines) acquire diversity generated elsewhere. These contrasting contributions can be explained by differences in region size and isolation, elucidating how the unique island-dominated geography of the Asian tropics drives their outstanding biodiversity.

  14. Monitoring in the Western Pacific region shows evidence of seagrass decline in line with global trends
    Short FT, Coles R, Fortes MD, Victor S, Salik M, Isnain I, et al.
    Mar Pollut Bull, 2014 Jun 30;83(2):408-16.
    PMID: 24746094 DOI: 10.1016/j.marpolbul.2014.03.036
    Seagrass systems of the Western Pacific region are biodiverse habitats, providing vital services to ecosystems and humans over a vast geographic range. SeagrassNet is a worldwide monitoring program that collects data on seagrass habitats, including the ten locations across the Western Pacific reported here where change at various scales was rapidly detected. Three sites remote from human influence were stable. Seagrasses declined largely due to increased nutrient loading (4 sites) and increased sedimentation (3 sites), the two most common stressors of seagrass worldwide. Two sites experienced near-total loss from of excess sedimentation, followed by partial recovery once sedimentation was reduced. Species shifts were observed at every site with recovering sites colonized by pioneer species. Regulation of watersheds is essential if marine protected areas are to preserve seagrass meadows. Seagrasses in the Western Pacific experience stress due to human impacts despite the vastness of the ocean area and low development pressures.

    PMID: 25210584 MyJurnal
    THE DIVERSITIES OF MANGROVE TREES AND OF THEIR ASSOCIATED GASTROPODS WERE ASSESSED FOR TWO MANGROVE REGIONS ON THE WEST COAST OF PENINSULAR MALAYSIA: Langkawi Island and Sungai Merbok. The mangrove area sampled on Langkawi Island was recently logged and replanted, whereas the area sampled in Sungai Merbok was part of a protected nature reserve. Mangrove and gastropod diversity were assessed in four 50 m(2) (10 × 5 m) sites per region. The species richness (S), Shannon Index (H') and Evenness Index (J') were calculated for each site, and the mean S, H' and J' values were calculated for each region. We report low tree and gastropod S, H' and J' values in all sites from both regions. For Langkawi Island, the mean S, H' and J' values for mangrove trees were S = 2.00±0, H' = 0.44±0.17 and J' = 0.44±0.17; the mean S, H' and J' values for gastropods were S = 4.00±1.63, H' = 0.96±0.41 and J' = 0.49±0.06. In Sungai Merbok, the mean S, H' and J' values for mangrove trees were S = 1.33±0.58, H' = 0.22±0.39 and J' = 0.22 ±0.39; the mean S, H' and J' values for gastropods were S = 4.75±2.22, H' = 1.23±0.63 and J' = 0.55±0.12. This study emphasises the need for baseline biodiversity measures to be established in mangrove ecosystems to track the impacts of anthropogenic disturbances and to inform management and restoration efforts.

  17. The Denser Canopy of Mangrove Drives the Structure of Insect Communities
    Setyawan YP, Wakhid, Suhadi
    Trop Life Sci Res, 2020 Oct;31(3):77-90.
    PMID: 33214857 DOI: 10.21315/tlsr2020.31.3.6
    Mangrove restoration in Trenggalek, East Java has resulted an age variation of mangrove ecosystem. Diverse species of insects predominantly found in mangroves were collected using yellow pan traps, swipe nets and by direct picking from three different sites. This research was conducted from April until August 2015. There are 9,181 individual insects associated with mangroves comprised of 42 species from 31 families and eight orders. The first site or the 15 years old mangrove (66.22% canopy cover) indicated the highest Shannon diversity index at 2.54, Evenness index of 0.32 and Margalef richness index of 4.84. The lowest diversity was recorded in the third site or the five years old mangrove (19.65% canopy cover), with the Shannon diversity index at 2.28, Evenness index at 0.26 and Margalef richness index at 4.59. The most abundant species located was the Eristena mangalis, with 1,724 individuals (relative abundance of 18.78%), followed by Monolepta sp. with 1,649 individuals (relative abundance of 17.96%). These are the phytophagous insects associated with mangrove leaves. This study concluded that the older mangrove ecosystem have a denser canopy that supports insect life.

  18. Fulltext Differences in meiofauna communities with sediment depth are greater than habitat effects on the New Zealand continental margin: implications for vulnerability to anthropogenic disturbance
    Rosli N, Leduc D, Rowden AA, Clark MR, Probert PK, Berkenbusch K, et al.
    PeerJ, 2016;4:e2154.
    PMID: 27441114 DOI: 10.7717/peerj.2154
    Studies of deep-sea benthic communities have largely focused on particular (macro) habitats in isolation, with few studies considering multiple habitats simultaneously in a comparable manner. Compared to mega-epifauna and macrofauna, much less is known about habitat-related variation in meiofaunal community attributes (abundance, diversity and community structure). Here, we investigated meiofaunal community attributes in slope, canyon, seamount, and seep habitats in two regions on the continental slope of New Zealand (Hikurangi Margin and Bay of Plenty) at four water depths (700, 1,000, 1,200 and 1,500 m). We found that patterns were not the same for each community attribute. Significant differences in abundance were consistent across regions, habitats, water and sediment depths, while diversity and community structure only differed between sediment depths. Abundance was higher in canyon and seep habitats compared with other habitats, while between sediment layer, abundance and diversity were higher at the sediment surface. Our findings suggest that meiofaunal community attributes are affected by environmental factors that operate on micro- (cm) to meso- (0.1-10 km), and regional scales (> 100 km). We also found a weak, but significant, correlation between trawling intensity and surface sediment diversity. Overall, our results indicate that variability in meiofaunal communities was greater at small scale than at habitat or regional scale. These findings provide new insights into the factors controlling meiofauna in these deep-sea habitats and their potential vulnerability to anthropogenic activities.

    The available knowledge of the round fungus beetle subfamily Cholevinae (Leiodidae) from the island of Borneo is reviewed, and the results of newly studied material presented. The currently known 30 species (of which 14 are newly described herein) represent the genera Micronemadus (one species), Catops (one species), Baryodirus (one species), Ptomaphaginus (14 species), and Ptomaphaminus (13 species). The following new species are described: Micronemadussondaicus Schilthuizen & Perreau, sp. n., Ptomaphaginusgrandis Schilthuizen & Perreau, sp. n., P.louis Schilthuizen & Perreau, sp. n., P.muluensis Schilthuizen & Perreau, sp. n., and P.isabellarossellini Schilthuizen, Njunjić & Perreau, sp. n., and Ptomaphaminuskinabatanganensis Njunjić, Schilthuizen & Perreau, sp. n., P.testaceus Schilthuizen & Perreau, sp. n., P.nanus Schilthuizen & Perreau, sp. n., P.marshalli Schilthuizen & Perreau, sp. n., P.hanskii Schilthuizen & Perreau, sp. n., P.sarawacensis Schilthuizen & Perreau, sp. n., P.layangensis Schilthuizen & Perreau, sp. n., P.microphallus Schilthuizen & Perreau, sp. n., and P.alabensis Schilthuizen & Perreau, sp. n. It is expected that the cholevine biodiversity of Borneo is still far from completely known. Nonetheless, provisional identification keys to all species known so far are presented.
