The mangrove forest are natural and renewable. resources Mangrove has the physical, chemicaland biological function which highly support the fulfillment of human needs and serve as a bufferbalance of the ecosystem in coastal areas. One of the functions associated with the mangrovebiological existence as a source of diversity of marine life. Marine life is affected by the presenceof mangrove forests among mangrove crab (Scylla serrata) to maintain the ecological balance andcause the energy cycle running fast. This study aims to determine the condition of environmentalfactors, the relative fitness and spatial distribution of mangrove crabin the mangrove forests BlockBedul Kali Segoro Alas Purwo National Park. Data from the study are described and classified bysimilarity of environmental factors, then performed multiple linear regression betweenenvironmental factors with relative fitness and spatial distribution of mangrove crabs. The resultsshowed that the average relative fitness mangrove crabs at all the research station is 69 with astandard deviation of 13.51. Spatial distribution of mangrove crab at any observation station isless than 1, so it can be concluded that the distribution is uniform. Environmental factors withrelative fitness mud crab significant correlation, but no significant correlation betweenenvironmental factors with the spatial distribution of mangrove crabs.

Holothurioidea well known as Sea Cucumber is one of the classes from the Echinodermata phylum. Sea cucumbers are benthic animals that move slowly. Currently they already identified about 1135 species. Their existence usually associated with abiotic factors such as water salinity, temperature, pH, wave motion, light intensity and the substrate. The ability of the Holothurioidea to adapt to the abiotic factors will affect species diversity. The research aims is to determine the species diversity in the intertidal zone at Pancur Shore of the Alas Purwo National Park. It includes the species composition, species diversity index and the index of equality The study was conducted on 14th-21st of June 2014, by using systematic plotting transect method. The results found: one order, one family, two generas and eight species. The Species diversity index of Holothurioidea at Pancur Shore is low (0.930) and the equality index  classified uneven (0.447).Keywords: Holothurioidea, intertidal, diversity, evennes

Abstract The aim of this study to find out the optimal level of salinity for the growth and survival of the mud crab (Scylla serrata). The weight of crab seeds were about 47.65-51.32 grams and the carapace length ranged from 64.35-71.30 mm, then put into 12 tanks (1 m x 1 m x 0.4 m) with a density of 4 crab seed per tank. During the maintenance of this test, mangrove crab was fed with fresh chicken intestines as much as 10% of its body weight per day. Water changes are carried out more than 150% per week. At the beginning of the experiment, each tank was conditioned to the same water salinity in all experimental units, namely 33 ppt. To see the effect of differences in salinity levels on the growth and survival of mud crabs, 4 treatments were made consisting of (A) 33 ppt salt content, (B) 31 ppt salt content, (C). The salt content is 29 ppt, and (D) the salt content is 27 ppt. From the results of this experiment, it is known that a decrease in the salt content of 4 ppt is the best treatment for the growth of mud crabs, but has no effect on the survival value.

Observation Method

Butterflies are one type of insect found in the green open space of Pontianak City. Butterflies can be used as bioindicators of environmental changes because butterflies are very sensitive to biotic and abiotic factors (Rizal, 2007). This study aims to obtain data and analyze the diversity of butterfly species in the green open space of Pontianak City. The study used a field observation method with sweeping net techniques and explored areas in three habitats namely Sylva Untan Arboretum, Untan S1 Forestry Campus and West Kalimantan Governor's Hall Pavilion. The three green open spaces were chosen based on the density and diversity of the vegetation. The results of the study found 22 types of butterflies. The same six types are found in three different types of open green space, namely Leptosia nina, Agamemnon Graphium, Papilio polytes, Hipolimnas bolina, Eurema hecabe, and Appias lybithea. The species diversity index at the Arboretum has a value of 2.74, Campus S1 Forestry Untan with a value of 2.19 and Pendopo Park with a value of 2.02. This value indicates that species diversity in green open space is classified as medium.Keywords: butterfly diversity, green open space, bioindicator

Abstract. Poedjirahajoe E, Sulityorini IS, Komara LL. 2019. Short Communication: Species diversity of mangrove in Kutai National Park, East Kalimantan, Indonesia. Biodiversitas 20: 3641-3646. Kutai National Park (KNP) in East Kalimantan, Indonesia is blessed with natural mangrove forests. However, there is only very little information relating to the species composition and mangrove diversity. Therefore, this study was conducted to assess the mangrove tree species diversity and richness in Kutai National Park, East Kalimantan, Indonesia. The study results showed that the mangrove trees density was 1,214 trees/ha in the line transect vegetation survey with 1.7 ha plot. The number of mangrove species in KNP was 17 from 6 families. The dominant species with large numbers of individuals were Rhizophora mucronata, Rhizophora apiculata, and Bruguiera sexangula. The diversity index was low in mangroves in Pandan Bay Estuary, and Kaba Bay compared to that in Lombok bay’s mangroves.

Abiotic Resources

National parks are forest ecosystems that contain biotic and abiotic resources. Biodiversity is the data and information necessary to understand the degree of loss of species diversity and formulate a sustainable alternative of decline in these resources. The research objective is to study the reciprocal relationship between elevation and habitat of a species in an ecosystem. Research conducted at the National Park (TN) Meru Betiri. The results show that there are spatial variabilities of the species diversity based on the elevation in the study area. Elevation is inversely proportional to species diversity index, the higher the elevation, the species diversity index tends to decline, but the index of the importance of endemic species have increased. Group stand structure and species composition is influenced by the level of elevation with their own environment.

Butterflies are species of insect found in all types of habitats. Butterflies can be used as bio-indicators of environmental change because butterflies are very sensitive to biotic and abiotic factors. The aim of this study to obtain data the diversity of butterfly species in several habitat types in the PT.Hutan Ketapang Industri. This study used observation method with a sweeping that is using insect nets and researchers are free to explore the area randomly for a specified time. This research was conducted in 5 Habitats, kerangas forest, peat swamp, lowland dipterocarps, riparian and wetlands. Five forest types are selected based on the density and diversity of forest vegetation. The results found 14 species with a total of 316 individuals. Based on the calculation of species diversity index of butterflies in five locations of 2.54212, shows that the diversity is classified as moderate and has an abundance index value of 0.963289 indicates that the abundance is classified as high. Then obtained a value of species wealth index of 2.75651 is classified as moderate and has a value of dominance index of 0.0868651 indicates that there is no dominant typeKeywords:  butterfly, diversity, indicator habitat, bioindicator
