Biodiversity can act as an indicator of the ecological system and as a medium for knowing species changes. Insects are living things in a world that has a high species diversity. One insect that has a functional role in the ecosystem is ants. The purpose of this study was to calculate and analyze diversity of the types of ants in four types of ecosystems and analyze the effect of habitat characteristics on the abundance of ants. Ant sampling using the hand sorting method was taken from the soil and litter parts in four ecosystems, namely secondary forest, ulin stands, oil palm plantations, and rubber stands in Sultan Thaha Syaifuddin Forest Park Batanghari District, Jambi Province. The results showed a total of 940 ants were obtained, from 296 individuals in Secondary Forest, 198 individuals in oil palm plantations, 307 individuals in ulin stand, 139 individuals in rubber stand. Ants are more commonly found in parts of the soil than litter. The highest ant diversity in the soil and litter is found in secondary forest. Environmental factors that influence the presence of ants in each ecosystem are soil temperature and thickness of litter. Keywords: ants, biodiversity, ecosystems, hand sorting, tahura.

Biodiversitas 21: 1326-1331. Natural habitat existence in oil palm plantation has high conservation value and plays an important role in maintaining biodiversity. However, different taxa may have different responses to the presence of natural habitats. This research was aimed to investigate the effect of natural habitat existence on ant and termite diversity in oil palm plantation. The field research was conducted in oil palm plantation located in Central Kalimantan, Indonesia. Twelve plots of oil palm plantation with different habitat characteristics were selected. Ants and termites were sampled using hand collection in six subplots for each plot. In total, 38 species of ants and 9 species of termites were collected from all research areas. The results showed that the area of natural habitats and the distance of oil palm field to natural habitats affected the diversity of termites in the oil palm plantation, but ant diversity did not show to be affected by the same conditions. Based on the generalized linear model, the area of natural habitats in the oil palm plantation had a negative relationship with the diversity of termites. In conclusion, the termite species community is more affected by natural habitats than ants in oil palm plantation.

Abstract The purpose of this study was to determine the habitat characteristics of the Sumatran Elephant in the Serbajadi District Forest. Data collection by looking at the use of habitat which is characterized by the distribution of faeces found in various habitat units in the home range of the Sumatran Elephant. The method used is observation with a track with a size of 3,600 m which is divided into 20 observation plots with a distance between plots of 100 m. The data obtained in the field were analyzed descriptively and presented in tabular form. The results of this study indicate that the Habitat Characteristics of the Sumatran Elephant in the Serbajadi District Forest chose habitat units with very dense canopy cover (>75%), moderate feed availability (26-50%), rare mineral source trees availability (< 3 trees/plot). availability of sparse scrubbing trees (<3 trees/plot), close to primary forest (0-500 m), low land elevation (0- 400 masl), gentle slope (0-20°), close to water sources (0-250m). Secondary forest/vegetation type and frequency of habitat use based on the findings of faeces that the Sumatran elephant most frequently visited was secondary forest than primary forest because the secondary forest was for feeding activities while the primary forest was used for resting and reproduction.

Context Oil palm plantations have become a dominant landscape in Southeast Asia, yet we still understand relatively little about the ways wildlife are adapting to fragmented mosaics of forest and oil palm. The bearded pig is of great ecological, social and conservation importance in Borneo and is declining in many parts of its range due to deforestation, habitat fragmentation and overhunting. Aims We assessed how the bearded pig is adapting to oil palm expansion by investigating habitat utilisation, activity patterns, body condition and minimum group size in a mosaic landscape composed of forest fragments and surrounding oil palm plantations. Methods We conducted our study in Sabah, Malaysian Borneo, in and around the Lower Kinabatangan Wildlife Sanctuary, a protected area consisting of secondary forest fragments (ranging 1200–7400ha) situated within an extensive oil palm matrix. We modelled bearded pig habitat use in forest fragments and oil palm plantations using survey data from line transects. Camera traps placed throughout the forest fragments were used to assess pig activity patterns, body condition and minimum group size. Key results All forest transects and 80% of plantation transects showed pig presence, but mean pig signs per transect were much more prevalent in forest (70.00±13.00s.e.) than in plantations (0.91±0.42s.e.). Pig tracks had a positive relationship with leaf cover and a negative relationship with grass cover; pig rooting sites had a positive relationship with wet and moderate soils compared with drier soils. Ninety-five percent of pigs displayed ‘good’ or ‘very good’ body condition in forests across the study area. Pigs also aggregated in small groups (mean=2.7±0.1s.e. individuals), and showed largely diurnal activity patterns with peak activity taking place at dawn and dusk. Groups with piglets and juveniles were more active during the day and less active at night as compared to overall activity patterns for all groups. Conclusions Our findings suggest that bearded pigs in our study area regularly utilise oil palm as habitat, as indicated by their signs in most oil palm sites surveyed. However, secondary forest fragments are used much more frequently and for a wider range of behaviours (e.g. nesting, wallowing) than adjacent oil palm plantations. These forests clearly remain the most important habitat for the bearded pig in the Lower Kinabatangan Wildlife Sanctuary, and their protection is a high conservation priority for this species. Implications Consistent bearded pig presence in oil palm is potentially an indication of successful adaptation to agricultural expansion in the study area. The apparently good body condition displayed by the vast majority of pigs in our study likely results from year-round cross-border fruit subsidies from surrounding oil palm plantations. The consistent diurnal activity displayed by groups containing piglets and juveniles may indicate predator avoidance strategies, whereas the substantial nocturnal activity we observed by other groups could suggest fewer threats for larger individuals. However, the overall effects of oil palm expansion in the region on bearded pig population health, foraging ecology, and movement ecology remain unknown.A

Abstract. Ramlah S, Santosa Y, Santoso N, Rushayati SB. 2021. The variation of bird diversity in various oil palm land cover in North Mamuju, West Sulawesi, Indonesia. Biodiversitas 22: 3068-3074. The development of oil palm plantations provides various positive impacts. On the other hand, this development is suspected to bring negative impacts on biodiversity, especially reducing bird species diversity. Based on the other research, well-managed oil palm plantations that maintain high conservation value areas have high species diversity. This study aimed to identify bird species diversity in different types of oil palm plantation land covers in North Mamuju. Data observation of bird species was performed using the transect method. There were 4 transects on each land cover. The results of this study showed that the young oil palm area had a high index of diversity and species richness. The high species diversity in the young palm area was caused by habitat variations. There was a water flow that provides more feed sources. The distance between the young oil palm area and secondary forest area affected the number of species, species richness and diversity of bird species. The category of insectivore guild which included aerial insectivores and insectivores was the dominant guild in all types of land cover, both in the number of species and the number of individual abundances.

Converting of tropical rain forest into plantation and agriculture land uses has been claimed as a main factor that affects to global warming and climate change. In order to provide a comprehensive information of the issue, a field observation on  peat properties in relation to CO2 emission under several land use types had been done  at Lubuk Ogong Village, Pelalawan District, Riau Province from May 2011-April 2012. Five land use types, namely A. mangium, bare land, oil palm, rubber, and secondary forest have been selected in the study site. Observations were made for chemical and physical properties, above and below ground C-stock and CO2 emissions. The results showed a higher variation of peat depth and a below ground C-stock was almost linearly with a peat depth. Below ground C-stock for each land use was around 2848.55 Mg ha-1, 2657.08 Mg ha-1 5949.85 Mg ha-1,  3374.69 Mg ha-1, 4104.87 Mg ha-1 for secondary forest, rubber, oil palm, bare land, and A. mangium, respectively. The highest above ground C-stock observed on a secondary forest was 131.5 Mg ha-1, followed by the four years A. mangium 48.4 Mg ha-1, the 1-2 years A. mangium 36.6 Mg ha-1, and the 4 years A. mangium 34.4 Mg ha-1. While, CO2 emissions in the study sites were 66.58±21.77 Mg ha-1yr-1, 66.17±25.54 Mg ha-1yr-1, 64.50±31.49 Mg ha-1yr-1, 59.55±18.30 Mg ha-1yr-1, 53.65±16.91 Mg ha-1yr-1 for bareland, oil palm, secondary forest, A. mangium, and rubber, respectively.

Isolation and identification of cellulolytic bacteria at fibric, hemic, and sapric peat in Teluk Bakung Peatland, Kubu Raya District, Indonesia. Biodiversitas 21: 2103-2112. Cellulose degrading bacteria was one of the microbial removers of organic matter contained in the soil into simpler monomers so that it can be utilized by other organisms. The objective of the research was to obtain cellulose-degrading bacteria found on fibric, hemic, and sapric peat in forest and shrubs (oil palm). The bacteria were isolated by pour plate method on 1% CMC media. Selected isolates were assayed quantitatively based on the activity of cellulase enzyme, identified with 16S rDNA. The density of cellulolytic bacteria in the secondary forest peat of fibric, hemic, sapric were 2.1x103 cfu/g, 5.9x104 cfu/g, and 4.9x104 cfu/g whereas, in the area of shrubs/oil palm peat fibric, hemic and sapric 6.9x104 cfu/g, 8.4x104 cfu/g and 3.4x105 cfu/g respectively. There were 19 bacterial isolates that have clear zones around the colony as degradation of cellulose had highest ability to degrade cellulose with clear zones of 5-7 mm. The strain of SB1.1.1 showed highest activity of cellulase enzyme 11.17 U/mL, followed by HH3.1.1 strain and SB2.3 7.83 U/mL. Based on the phylogeny tree, strain SB1.1.1 and HH3.1.1 have the closest kinship relationship with Bacillus cereus with a kinship relationship of 100%, while SB2.3 has the closest kinship relationship with Bacillus stratosphericus with a relationship of 99.85 %.

Intergrated Forest for Conservation Education of Wan Abdul Rachman (IFCE WAR) Great Forest Park is a conservation forest zone which has natural area and cultivated area.  The natural area in Wan Abdul Rachman Great Forest Park consists of secondary forest, whereas the cultivated area consists of agroforestry with cacao plants and agroforestry with coffee plants. The different land use in both areas caused the difference in carbon sink specifically in litter and soil. The research was aimed to study the difference of litter and soil carbon stock in natural and cultivated area in IFCE WAR Great Forest Park.  The observation plots included in the current study was determined using purposive sampling method. The research was conducted in June until August 2015. Data was analyzed using analysis of variance and continued with honestly significant difference test. The results showed that there was no difference of litter carbon stock in cultivated area and natural area in IFCE WAR Great Forest Park, whereas the soil carbon stock in natural area was higher than that in cultivated area.

Diversity, permanence, and activity of terrestrial arthropods were investigated in four areas of different land use in the lowlands of the Pacific coast of Colombia with the aim to identify potential predator species for the palm root borer, Sagalassa valida. Ten pitfall traps were established along a 100 m transect in four areas: a secondary forest, a 20 year.-old peach palm plantation, and two hybrid oil palm plantations of three and seven years of age, respectively. Twenty-two collections were made covering a whole year. All ants were identified to species or morphospecies level, the other arthropods to order or where possible to family level. In total, 50,603 arthropods were captured, the most abundant were ants (37.0 %), followed by Collembola (35.4 %), Acari (10.6 %), Coleoptera (7.0 %) and Diptera, Hemiptera and Araneae in almost equal numbers (around 2.5 %). Orthoptera (92 % Gryllidae) were present in all collections, always at low numbers. The highest number of ants were recorded in the oil palm transects; Diptera, Hemiptera and Orthoptera were more numerous in the secondary forest, Acari, Araneae and Collembola in the palm transects. Ectatomma ruidum was by far the dominant ant species (84.9 % of all specimens) and absent from only 20 of the 880 captures. The second most frequent ant genus were army ants with two species, Labidus praedator and L. coecus. Rainfall, even area-wide flooding, and temperature did not explain variability in captures of any taxonomic group satisfactorily. We conclude that E. ruidum might be the predator to provide control of the root borer and recommend further studies on its efficiency.

Balancing the goals of sustainable planning under climate and land use change (CLUC) with ecosystem service functions is a huge challenge for the management and programming of protected areas today. We construct a new evaluation framework towards the perspectives of sustainable land management based on the choice experiment (CE) model, and apply it to investigate the public’s preferences for the forest parks in Taiwan. This study found that implementing organic farming, increasing species populations, increasing the acreage of secondary forest area, and developing an integrated framework for ecotourism would best satisfy the public’s preferences for sustainable land use management. Second, we identify that the heterogeneity of the public’s preferences for forest park management varies depending on whether individuals are (1) members of environmental groups, (2) agricultural landowners, and (3) residents of the municipality. Third, we find integrated land use programs generate the highest welfare values among scenarios comprising different financial attributes.
