Fauna bentik (makrozoobentos) telah dianggap sebagai salah satu kriteria untuk menilai keberhasilan program restorasi mangrove. Kajian korelasi karakteristik lingkungan terhadap makrozoobentos di kawasan reboisasi mangrove Kepulauan Seribu telah dilakukan pada bulan Maret 2014. Hal ini bertujuan untuk mengetahui pengaruh yang diakibatkan oleh karakteristik lingkungan (parameter fisika kimia perairan) terhadap kepadatan makrozoobentosnya. Data biota makrozoobentos di kawasan reboisasi mangrove Kepulauan seribu dikumpulkan dengan membuat transek garis dan plot yang ditarik dari titik acuan (tegakan mangrove terluar) dan tegak lurus garis pantai sampai ke daratan, dimana pengamatan dilakukan di tiga stasiun (pulau). Sebanyak 6 famili dan 6 spesies makrozoobentos telah ditemukan di kawasan reboisasi mangrove Kepulauan Seribu. Komposisi dan kepadatan spesies tertingginya adalah Littoraria scabra. Karakteristik lingkungan yang diukur tidak begitu berbeda antar stasiun serta juga tidak melebihi ambang batas baku mutu. Semakin rendah konsentrasi salinitas dan DO, maka kepadatan makrozoobentosnya semakin tinggi, sedangkan semakin tinggi konsentrasi pH perairan, maka kepadatan makrozoobentosnya semakin menurun. Kemudian parameter suhu dengan kepadatan makrozoobentos tidak memiliki pengaruh.THE EFFECT OF ENVIRONMENTAL CHARACTERISTICS OF MAKROZOOBENTOS IN MANGROVE REFORESTATION AREA OF SERIBU ISLANDS, INDONESIA. Benthic fauna (macrozoobenthos) has been considered as one of the criteria for assessing the success of a mangrove restoration program. A correlation study of environmental characteristics of macrozoobenthos in the Seribu Islands mangrove reforestation area was carried out in March 2014. It aims to determine the effect caused by environmental characteristics (water physical-chemical parameters) on its macrozoobenthos density. Data of macrozoobenthos biota in the Seribu Islands mangrove reforestation area were collected by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland, where observations were made at three stations (islands). Six families and six macrozoobenthos species have been found in the Seribu Islands mangrove reforestation area. The composition and density of the highest species were Littoraria scabra. The measured environmental characteristics were not very different between stations and also did not exceed the quality standard threshold. The lower the salinity and DO concentration, the higher the density of macrozoobenthos, while the higher the concentration of water pH, the lower the density of macrozoobenthos. Then the temperature parameters with macrozoobenthos density had no effect.

Mangrove reforestation is often carried out in various regions or regions, but information about the relationship of environmental factors and the distribution of fauna associations is still very minimal. The Principal Component Analysis (PCA) study on the correlation of environmental factors and the spatial distribution of the molusks community in the Seribu Islands mangrove reforestation area was conducted in March 2014 with the aim of analyzing environmental factors for the diversity and presence of the molusks. Environmental factors are measured insecurely, while the moluccan community is collected by making line transects and plots measuring 10 x 10 m2 and in the size of 10 x 10 m2, a small plot of 1 x 1 m2 is made. The results of the study show that environmental factors are not so different between stations and do not exceed the quality standard for the lives of 4 species of mollusks, where the parameters of aquatic pH are the environmental factors that most influence their distribution.Keywords: environmental factors, distribution, mollusks community, mangrove reforestation, Seribu Islands

AbstractThe study of the environmental characteristics and conditions of macrobenthic fauna in the mangrove reforestation area of Pramuka, Panggang, Karya, and the Seribu Islands was carried out in April 2014. This study aims at the basic data in mangrove management in Indonesia, especially after mangrove planting. Measurement of environmental characteristics is carried out by in-situ methods while collecting macrobenthic fauna by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland. The results of the study show that the measured environmental characteristics are not very different between stations and also do not exceed the quality standards for marine life. A total of 6 macrobenthic fauna species have been found with varying densities. The highest density is at Station 3 (05.00 ind/m2) and the lowest is at Station 1 (02.00 ind/m2). In addition, the macrobenthic fauna Atilic (Columbella) scripta, Metopograpsus latifrons, Littoraria scabra, Saccostrea cucculata and Cardisoma carnifex are associated or closely related to silt or sand substrates. Furthermore, the water quality parameters that most determine the distribution and density of macrobenthic fauna in the mangrove reforestation area of Pulau Pramuka, Panggang and Karya Seribu Islands District are pH.

After a minor coral bleaching event in 1993, a more dramatic episode occurred in Tahiti from March to July 1994. Coral bleaching was recorded along four continuous 25-m-long line transects. Physico-chemical parameters of the sea water (temperature, salinity, dissolved oxygen and pH) were noted once a week, and solar UV-B flux was recorded daily before and during the bleaching episode. Results emphasized the importance of the taxonomic position of coral in susceptibility to bleaching. The evolution of bleaching through time was related to mean daily solar UV-B flux and sea-water temperature. Moreover, comparison of the 1993 and 1994 data suggested temperature and/or UV-B thresholds that may elicit minor or severe bleaching events.

The abundance of macro benthic organisms was observed from a migratory bird visiting lake in Jahangirnagar University, Savar for a period from July 2016 to June 2017. A total of 22 species belonging to three phyla (viz. Mollusca, Annelida and Arthropoda) and 14 families was recorded with maximum abundance in summer season and minimum in winter season. Molluscan population (37%) was dominant in benthos, followed by Annelida (31%) and Arthropoda (28%). Average values of water temperature, dissolved oxygen and water pH were within standard permissible ranges in the aquatic habitats of the country. Water and soil parameters were in suitable ranges for the growth and abundance of benthos. Correlation indicated that Mollusca and Annelida were closely dependent on water temperature, water pH, water depth, soil organic carbon and soil organic matters, whereas Arthropoda had less dependency on them. In the present study lower Shanon-Wiener diversity index (2.55-2.92) and low species richness (18-24) clearly demonstrated that the lake is moderately polluted. J. Biodivers. Conserv. Bioresour.
