Changes in landscape ecology between nature reserve and palm oil plantation in West Java, Indonesia based on the observations of macrofungal population

Abstract. Arko PF, Sudirman LI, Qayim I. 2021. Changes in landscape ecology between nature reserve and palm oil plantation in West Java, Indonesia based on the observations of macrofungal population. Biodiversitas 22: 4526-4537. As the biggest tropical country in Southeast Asia with the third-largest forest, Indonesia has limited data on macrofungal diversity. The limitation of the data is due to the lack of study on macrofungi in high biodiversity locations such as Dungus Iwul Nature Reserve (CADI). The purpose of this study was to determine and analyze the population of macrofungal species caused by the conversion in landscape structure (fragmentation and land-use change) that occurred in CADI patch and oil palm plantation of PT Perkebunan Nusantara VIII (PTPN) matrix, Cigelung, West Java. The sampling method used was opportunistic sampling assisted by line intercept. The macrofungal identification was based on morphological characters. The analysis of community ecology was performed in R programme. The results showed that macrofungal population and diversity in CADI were the highest, followed by PTPN planted in 2004 and planted in 2003, with a significant difference among the three study locations. The community dominance index shows the opposite, with the highest in PTPN 2003 and the lowest in CADI. These results showed changes in macrofungal population and diversity from the conversion in landscape structure. There were eleven indicator species in CADI, two species in PTPN 2003, and five species in PTPN 2004.

The assessment of benthic ecosystems and substrate profile of Bawean Island East Java Province

Bawean Island is located 80 km north of the East Java mainland. This island is known to have a natural coral reef ecosystem that is still preserved. However, the condition of the coral reefs on the island has not been widely studied and documented. This study aims to determine in detail the substrate profile and to analyze the condition of the coral reefs that are scattered along the coast of Bawean Island. Profiling of the bottom substrate and benthic habitat was carried out using the Line Intercept Transect method at 14 dive points. Furthermore, the percentage of coral coverage and other types of substrates is calculated. The results showed that in general the condition of coral reefs in Bawean Island was in the range of poor to good conditions (% living coral cover <25% - 74%). However, the condition of coral reefs and benthic habitats on Bawean Island is threatened by sea sand mining and the use of destructive fishing method. Based on the condition of the coral reefs, the waters of Bawean Island was recommended as one of the marine protected areas in East Java.

Study on suitability of Derawan Island as marine tourism destination towards development of sustainable tourism in the new capital city candidate of Indonesia

Derawan Island is one of the leading tourist destinations in Kalimantan Timur Province which is a candidate for the new capital city of Indonesia. Marine tourism on Derawan Island relies on the potential of marine resources so that a suitability study is needed for the development of sustainable tourism. This study aims to determine the suitability of marine tourism, especially the interest in diving and snorkeling in sites of Derawan Island. Data collection was carried out by surveying in December 2020 at five snorkeling and six popular dive sites in Derawan Island. Data on coral community, the number of coral fish species, and the water quality parameters are used to analyze the suitability of marine tourism. Line Intercept Transect (LIT) method was used to collecting coral community data, Underwater Visual Census (UVC) method was used to collect data on the abundance of reef fish species, and in situ water quality parameters. Tourism suitability index formula (IKW) using the four classification marine tourism suitability matrix was used to analyze the data. The results of the analysis show the suitability index for diving tourism as a whole is in suitable to very suitable category, while the snorkeling tourism suitability index is in the suitable category.

Predicting canopy cover of diverse forest types from individual tree measurements

Quantifying tree canopy cover is fundamental to applications in forestry and ecology, but estimates vary substantially depending on type of field measurement, imagery, or active sensing used. Our objective was to improve estimates of stand-level canopy cover from standard tree inventory measurements, using representative data collected across diverse forest plant association groups across Oregon, USA. Canopy cover was measured with line intercept sampling on 1706 inventory plots and compared to calculations from individually tallied trees. We investigated adjustments of tree crown area equations, adjustments of crown overlap factors, and modeling from climatic variables and standard forest measurements to estimate line intercept cover. Estimates based on simple crown width equations adjusted for tree social position and caps on maximum cover, had the lowest error (RMSE = 14% cover) of crown width approaches across all vegetation types. Random crown overlap applied to unadjusted crown area only performed well in drier forest types and was unable to match high line intercept cover levels (>90%) often found in productive forest types. Although statistical models had somewhat greater precision than the simpler crown-width summation approaches (RMSE of 12%), accuracy was comparable. The greater flexibility of crown width summation approaches could make them more useful in forestry applications and beyond our study area.

Laju Sedimentasi Di Perairan Ekosistem Terumbu Karang Kampung Yakore Distrik Demta Kabupaten Jayapura

Sedimentation can be one of the factors that limit coral life because it can cover coral polyps, in high numbers it can even cause coral death. The purpose of this study was to determine the rate of sedimentation in the coral reef ecosystem and to determine the condition of coral reef cover in the waters of Kampung Yakore. This research was carried out from January to May 2021. The method used in this study was to collect sediment in a sediment trap for 14 days and the LIT (Line Intercept Transect) method to observe the condition of live coral cover. Data were collected at 3 stations at a depth of 3 m and 5 m. The results showed that the sedimentation rate in the waters of Kampung Yakore was moderate to very heavy where the highest sedimentation rate was at station 3 with a depth of 5 m. The sedimentation rate ranged from 30.28 – 67.74 mg/cm²/day at a depth of 3 m. Meanwhile, at a depth of 5 m, the sedimentation rate ranged from 68.30 – 133.21 mg/cm²/day. This shows that the sedimentation rate in the waters of Kampung Yakore is at a very heavy impact level. It is suspected that the high sedimentation rate is caused by the time when data collection is carried out during the rainy season so that the river discharge is getting bigger and carrying sediment to the sea. The percentage of live coral cover in the waters of Kampung Yakore was classified as "moderate" to "good" with percentages ranging from 39.28% - 71.76% at a depth of 3 m and ranging from 30.7% - 56.12% at a depth of 5 m. The highest percentage of the cover was at station 2 with a depth of 3 m, which was 71.76%.Key Words: Sedimentation Rate; Coral Reef Ecosystem; Coral Cover; Yakore VIllage

Tutupan Terumbu Karang pada Kedalaman Berbeda di Perairan Pantai Batu Sungu, Desa Les, Kabupaten Buleleng

Bali island has many magnificent underwater coral reef gardens that attract tourists. Besides Pemuteran and Menjangan island waters, Batu Sungu water has also potential to be a new tourist destination. Thus, to determine the potency and management plan in Batu Sungu waters, this research aimed to examine the overall coral cover, coral growth forms, other benthic forms, and each of their components in 5 and 10 m depths. The overall coral cover, coral growth forms, other benthic forms, and each of their components were counted by using the Line Intercept Transect (LIT) method. Before collecting data, study sites were observed by using the Manta Tow method. Data were collected in 2 depths (5 dan 10 m) with 5 sites each (replicates) that separates within 50 to 150 m. A 25 m LIT was spread parallel to the coastline above the reefs. Live coral colonies, other benthic forms below the transects were measured for the number, length, and growth forms. Water quality was measured in situ (temperature, current, and clarity) and ex situ (pH). Results showed that the category of coral coverage in Batu Sungu water is "good” in 5 m and "moderate” in 10 m whereas there was no significant difference among each component of the overall coral cover. The most dominant coral growth form among the 2 depths was Coral Massive whereas significantly abundant in 5 m. Moreover, the number of Coral Foliose was found significantly high in the same depth. Other coral growth forms were relatively similar in numbers in two depths. As likewise, the cover of other benthic forms and its component were not significantly different among two depths, except Dead Coral with Algae which significantly plentiful in 5 m. Sand was dominantly found in two depths with no significant difference. Furthermore, Coraline Alga was only observed in 5 m, however, there were no Macroalga and Alga Assemblages found at this depth. It is assumed that the similarity number of the overall coral cover, coral growth forms, other benthic forms, and each of their components is related to the alikeness of water quality among the two depths.

CORAL REEF COVER RELATIONSHIP TO POMACENTRIDAE AND PHYTOPLANKTON CORAL FISH IN KASIAK ISLAND OF WEST SUMATRA PROVINCE

Kasiak Island is one of the islands located in the waters of Pariaman, West Sumatra, and located right in front of Pariaman City. Around the sea, the island is surrounded by coral reefs and is a protected area. In the aquatic area of Kasiak Island has never been conducted research on the relationship of coral reef cover to the coral Pomacentridae and phytoplankton. Therefore, it is necessary to conduct research on this matter in the waters of Kasiak Island, West Sumatra Province. Data collection of coral reef cover is done by the LIT (Line Intercept transect) method with a transect length of 50 meters at a depth of 5 meters using scuba equipment. Coral fish observation is done by UVC (Underwater Visual Census) method with a transect length of 50 meters and an observation area of 2.5 meters left and right at a depth of 5 meters. Phytoplankton sampling is conducted during the day at 11.00 to 15.00 WIB at five points of the station with a depth of 5 meters using Vandorn water sampler volume 2 L with a total take of 100 L, then filtered using Plankton net no 25 and inserted into a sample bottle of 125 ml, then preserved using Lugol 4% as much as 4-6 drops, after which analyzed in the laboratory. Based on the results there is a very strong relationship between coral cover to the abundance of coral fish, where coral cover contributes to the abundance of coral fish by 93.87%, which means that the higher the percentage of coral cover the more species and abundance of coral fish are found. Then the a strong relationship between coral reef cover and phytoplankton abundance, where coral reef cover contributes to the abundance of phytoplankton by 56.37%, which means an increase in the percentage of coral reef cover along with the increasing abundance of phytoplankton.

POPULATION CONDITIONS OF ECHINOIDEA AND CORAL REEF COVERS IN PONCAN GODANG ISLAND, SIBOLGA, NORTH SUMATERA

Poncan Godang Island is included in the appropriate category based on the suitability of land for the Sibolga tourist area, with the presence of tourism activities that can also affect the amount of biodiversity in it. Considering the importance of coral reefs for biodiversity and sea urchins which also have a role in coral reef ecosystems, it is necessary to conduct research on the condition of sea urchins population and the percentage of coral reefs on Poncan Godang Island. Sea urchin and coral reef data were collected using the Line Intercept Transect (LIT) method by monitoring directly on the transect line along 50 meters. The results obtained indicate that the population of sea urchins in the waters of Poncan Godang Island, North Sumatra can be described, that sea urchins do not affect the coral reef ecosystem because at stations 1 and 5 there is no sea urchin and the percentage of coral cover is classified as bad, but at station 3 there are 32 individuals with coral reef cover conditions, while at stations with The percentage of good coral cover is that at station 4 there are only 25 individuals, as well as at station 2 where the percentage of coral cover is higher than station 3 and there are no sea urchins

Coral Reefs Health Status in the East Java: a Case Study in Banyuwangi, Situbondo, Probolinggo

Coral reef ecosystems are among the most productive natural biodiversity resources in tropical coastal areas, within seagrass beds and mangrove forests. Besides, coral reefs have very high ecological impacts and economic value that are managed well and sustainably. Also, healthy ecosystems will undoubtedly provide more incredible benefits and values, so studies need to be conducted to determine the health of coral reefs. While P2O LIPI is an institution that is the guardian of coral reef health data in Indonesia, there is limited information related to the coastal areas of East Java that has not been widely reported. This study aimed to find out the percentage of living hard corals and the health status of the ecosystem at three reef sites: Banyuwangi, Situbondo, and Probolinggo. Field surveys were carried out in June-July 2019, using the Line Intercept Transect (LIT) method. The materials used in this study are Self-Contain Underwater Breath Apparatus-SCUBA diving equipment, roll meters, and an underwater camera. The results showed that the hard coral cover living in Banyuwangi accounted for 28.91%, Situbondo was 31.20%, and Probolinggo (34.77%). Therefore, this study interpreted that the coral reef ecosystem was a moderate category (25% - 49.9%).

Shallow-Water Species Diversity of Common Intertidal Zoantharians (Cnidaria: Hexacorallia: Zoantharia) along the Northeastern Coast of Trinidad, Southern Caribbean

Zoantharians are colonial cnidarians commonly found in shallow tropical Caribbean coral reefs, and are known to be globally distributed. Common species in genera Zoanthus and Palythoa occur at Toco, Trinidad, where they are more abundant than their Scleractinia counterparts relative to benthic coverage. In this study, distribution, morphological and molecular data were collected to determine species and symbiont identification to provide more insight on zoantharians. The Line Intercept Point (LIT) transect method recorded coverage at three sites: Salybia (SB), Pequelle (PB), and Grande L’Anse (GA) Bays along the northeastern coast. Variations in morphology, such as tentacle count, oral disk color and diameter were collected from colonies in situ. All specimens were zooxanthellate, and molecular and phylogenetic analyses were done by sequencing the cytochrome oxidase subunit I (COI) gene, and the internal transcribed spacer (ITS) region for species and symbiont identification, respectively. Results showed mean Zoantharia percentage cover was 32.4% ± 5.1 (X ± SE) at SB, 51.3% ± 6.5 (PB), and 72.2% ± 6.1 at GA. Zooxanthellate zoantharians were identified as Palythoa caribaeorum, Palythoa grandiflora, Zoanthus pulchellus, and Zoanthus sociatus. Symbiodiniaceae genera were identified as Cladocopium and Symbiodinium in Palythoa and Zoanthus spp., respectively. Although this is the first molecular examination of zoantharians, and their symbionts in Trinidad, more research is needed to identify and document species distribution and symbiont biodiversity to understand their ecology in these dynamic ecosystems.

Bioecology of coral reef in Panjang Island of Central Java Indonesia

Coral reefs currently are suffered from natural factors along with increasing anthropogenic activity. Panjang Island, a small reef island located in Jepara Regency, may also be experiencing such conditions. Therefore, this work was aimed to observe the condition of the coral cover of Panjang Island. Line intercept transect was applied to survey the coral cover and mortality index from fourteen stations. Insitu data consisted of the bottom substrate composition of the reefs and the physical parameters of the sea. The secondary data, i.e. coral reef area maps from 2001 to 2019 were taken from Landsat Image 7 and 8, data of wind were obtained from www.ogimet.com, while tidal data were collected from BMKG. The bathymetry was determined from the Geospatial Information Agency data, salinity global analysis forecast Phy 001.024 (CMEMS). Sea surface temperature (SST), and chlorophyll-a distribution were analyzed using ENVI software. The result showed that Panjang Island has a poor to the moderate condition of hard coral. Two out of six categories of abiotic and dead coral were found to be high. The mortality index of coral was in the high category (average 0.52). During research periods the sea waters were characterized by high sea surface temperature (29.34-30.94°C), chlorophyll-a was also tended to be high (0-2.65 mg.m-3), and an average of salinity was high 32 ‰. The weak currents came to all sides of the island, therefore the coral reef was not exposed to extreme currents. The waves came from the east, then the energy decreases after being blocked by coral reefs on the eastern side of the island, so that coral reefs in the northeast and south sides were safer to be exposed. The results suggest that hydrodynamic ecology directly or indirectly affected the percentage of coral cover and mortality index at the reefs of Panjang Island.

STRATEGI PENGELOLAAN EKOSISTEM TERUMBU KARANG DI DAERAH WISATA AIR TANJUNG BENOA DAN JEMELUK AMED, BALI

Tanjung Benoa and Jemeluk Amed are two famous marine tourism sites in Bali. This study aims to determine the state of coral ecosystem in its life form, factors associated with coral damage, and the strategy to manage coral in those two area. We used two methods: Line Intercept Transect (LIT) and SWOT. The live coral coverage condition in Tanjung Benoa is in moderate and worse category. While the Jemeluk Amed is in moderate level and good condition, respectively. Factors causing damage to coral ecosystem are: the corals are under pressure, some corals are already bleaching, the anchoring activity and oil spill from ships, and algae. The coral reefs ecosystem in Tanjung Benoa and Jemeluk Amed can be sustained in good condition with government support and NGOs in the development of environmentally friendly activities and monitoring studies, implementation of coral reef preservation rules (prohibition of taking coral reefs) and colaboration of the community, government, and NGOs to carry out coral reef rehabilitation and monitoring studies. As one of the tourism area in Bali, the role of universities are needed for continuous research on the state of coral reefs to maintain environmentally friendly and sustainable tourism.Keywords: Coral reef; Life form; Strategy; Marine conservation.

Kondisi Terumbu Karang di Perairan Gili Gede, Sekotong Lombok Barat

Protection and sustainable data collection are very important in order to protect the coral reef ecosystem. This research was conducted to monitor and determine the condition of coral reefs in the eastern part of Gili Gede Island, which is administratively located in Sekotong Sub-District, West Lombok Regency, NTB. The method used is Line Intercept Transect (LIT). Furthermore, the starting point of the transect stretch is recorded using GPS coordinates and the depth gauge is used to estimate the depth of the water. The results showed that the status of coral reefs tended to be badly damaged with the mean value of all stations (21.92%). Fishery activities and pressure from the land are thought to be several factors that tend to affect the poor coastal ecosystem

Which Method for Which Purpose? A Comparison of Line Intercept Transect and Underwater Photogrammetry Methods for Coral Reef Surveys

The choice of ecological monitoring methods and descriptors determines the effectiveness of a program designed to assess the state of coral reef ecosystems. Here, we comparer the relative performance of the traditional Line Intercept Transect (LIT) method with three methods derived from underwater photogrammetry: LIT on orthomosaics, photoquadrats from orthomosaics, and surface analyses on orthomosaics. The data were acquired at Reunion Island on five outer reef slopes and two coral communities on underwater lava-flows. Coral cover was estimated in situ using the LIT method and with LITs and photoquadrats digitized on orthomosaic. Surface analyses were done on the same orthomosaics. Structural complexity of the surveyed sites was calculated from digital elevation models using three physical descriptors (fractal dimension, slope, surface complexity), and used to explore their possible influence in coral cover estimates. We also compared the methods in terms of scientific outputs, the human expertise and time required. Coral cover estimates obtained with in situ LITs were higher than those obtained with digitized LITs and photoquadrats. Surfaces analyses on orthomosaics yielded the lowest but most the precise cover estimates (i.e., lowest sample dispersion). Sites with the highest coral cover also had the highest structural complexity. Finally, when we added scientific outputs, and requirements for human expertise and time to our comparisons between methods, we found that surface analysis on the orthomosaics was the most efficient method. Photoquadrats were more time-consuming than both in situ and digitized LITs, even though they provided coral cover estimates similar to those of digitized LITs and yielded more than one descriptor. The LIT in situ method remains the least time-consuming and most effective for species-level taxonomic identifications but is the most limited method in terms of data outputs and representativeness of the ecosystem.

Coral Reef Coverage and Reef Fish Abundance in Menyawakan Island, Karimunjawa

Karimunjawa is one of the National Parks in Indonesia, a marine conservation area known for its diverse coral reefs, and mangrove forest. This study aims to determine coral reef status in Menyawakan Island at the northwest part of Karimunjawa Archipelago. Coral coverage as well as reef fish data were collected from the South, West, North, and East side of Menyawakan Island. Surveys were conducted at a depth of 5 and 10 meters, using the Line Intercept Transect (LIT) for coral coverage and visual census for reef fish abundance. The highest coral cover, categorized as good condition, was found in the North side of Menyawakan Island at a depth of 5 m (64.94%). Pomacentrus shows the greatest abundance with 291 individuals on the South side of Menyawakan Island. Overall coral cover in Menyawakan Island is categorized as medium to good condition, while the highest reef fish abundance is dominated with family of Pomacentridae, which are native habitat in coral reef area.

Evaluation of rangeland condition in miombo woodlands in eastern Tanzania in relation to season and distance from settlements

Miombo woodlands sustainability in east and south-central Africa is threatened by human activities, including overgrazing. This study investigated seasonal variations in rangeland condition in three grazed areas in miombo woodlands in eastern Tanzania. Transect lines were established across the grazing areas, sampling points were identified and marked at every 10% of the length of transect line. Sampling points were categorised in different distances with respect to settlement. The line intercept method was used to collect data on vegetation cover and forage distribution, while herbaceous forage biomass was estimated using a disc pasture meter. A total of 118 different plant species were observed and grasses comprised 40.6% of all herbaceous species. Bothriochloa pertusa, Cynodon plectostachyus, Hyparrhenia rufa and Urochloa mosambicensis grass species dominated miombo grazed areas in various seasons and distances. These perennial grass species are desirable and indicated moderate grazing activities in miombo. Season affected grass cover, herbaceous forage biomass and nutritional composition. Grass cover and forage biomass were at the lowest during late dry season while forage nutritional quality was best during early dry season. Distance from settlement had no effect on grass cover and herbaceous forage biomass. Rangeland condition was generally fair, livestock stocking rate in continuously grazed drylands should be set at the lowest monthly forage biomass in order to ensure grazing land sustainability.
