Soil Arthropod

Coal mining can disrupt the balance of the ecosystem, including the soil environment ecosystem as a habitat for soil arthropods. This study aims to see the soil arthropod family, relative density, diversity, dominance and evenness of soil arthropods in the revegetation area of the ex-mining area of PT. Bara Alam Utama. The re-search was conducted in the revegetation area of the former coal mine area of PT. Bara Alam Utama in Lahat district, South Sumatra. The research area consists of 8 location points, namely natural areas, revegetation areas of age 7,6,5,4,3,2 and 1 year. The study was conducted using an exploratory survey method, sampling was car-ried out based on the purposive sampling method by drawing a 100 m long transect with 5 sample plots inside measuring 20 x 10 m at each revegetation age. The results showed that the highest soil arthropod diversity index was found at the 3 year old revegetation location (H = 0.915) and the highest soil arthropod evenness index was at the 3 year old revegetation location (e = 0.17), while the highest soil arthropod dominance index was at 5 year old revegetation location (D = 0.886) which causes the 5 year revegetation location to have the lowest soil ar-thropod diversity index and evenness index (H = 0.351 and e = 0.054), while the lowest soil arthropod domi-nance index value is at the 3 year old revegetation location (D = 0.667), so it can be seen that there is a correla-tion between the diversity index and the evenness index of soil arthropods where both are inversely proportional to the results of the calculation of the dominance index. The high and low diversity index at each research loca-tion is influenced by abiotic factors (pH, soil temperature and soil moisture), age of revegetation and type of vegetation

AbstrakEchinodermata merupakan salah satu kelompok invertebrata yang memegang peranan penting, baik secara ekologi maupun ekonomi. Pengetahuan tentang organisme ini sangat dibutuhkan terkait dengan keberadaannya di alam yang semakin tergerus oleh pembangunan dan aktivitas manusia yang tidak ramah lingkungan. Penelitian ini bertujuan untuk mengetahui struktur komunitas Echinodermata di kawasan intertidal Gili Meno, Lombok Utara, yang dilakukan pada bulan April 2018 di 6 stasiun pengamatan yang tersebar di kawasan intertidal. Pengambilan data dilakukan dengan metode belt transect dengan pengulangan sebanyak 2–4 kali pada setiap stasiun, dengan luas transek 100 m2. Hasil pengamatan menunjukkan bahwa ditemukan 13 spesies yang berasal dari 4 kelas Echinodermata, yaitu Asteroidea (1 spesies), Echinoidea (4 spesies), Holothuroidea (4 spesies), dan Ophiuroidea (4 spesies). Hasil penghitungan indeks ekologi menunjukkan bahwa indeks keanekaragaman komunitas Echinodermata berkisar antara 0,16–1,36 (kategori rendah-sedang). Indeks dominansi di setiap stasiun berkisar antara 0,32–0,94 (kategori rendah-sedang), sedangkan indeks kemerataan sebesar 0,25 (kategori rendah). Hal ini menunjukkan bahwa stabilitas komunitas Echinodermata di kawasan intertidal Gili Meno tergolong rendah. Hasil penelitian ini diharapkan dapat menjadi acuan dalam pembangunan kawasan wisata yang ramah lingkungan tanpa mengabaikan keberadaan sumber daya hayati laut di kawasan Gili Meno, Lombok Utara.Abstract Echinoderms are one group of invertebrates that play an essential role, both ecologically and economically.

For gauging suitability of zygopteran odonates as bioindicators of ecosystems, an attempt was made to record the seasonal diversity of damselflies from seven different types of habitats in Paschim Medinipur District, West Bengal covering 14 land use sites. The study revealed existence of 19 species of damselflies belonging to 10 genera under two families. While the riparian zone had maximum number of species (15), paddy field had the lowest number (six). Ceriagrion coromandelianum and Agriocnemis pygmaea were the most common species. C. coromandelianum was eudominant in grassland and wetland-forest interface, whereas A. pygmaea was eudominant in fish pond and paddy field. Six species, viz., Paracercion calamorum, P. malayanum, Pseudagrion australasiae, P. decorum, P. spencei, and P. microcephalum were confined only to the riparian zone. Maximum abundance of damselflies was found in the riparian zone and minimum in the paddy field. Damselflies exhibited a distinct peak in March–April and a lesser peak in September–October. Most of the land use patterns exhibited similar zygopteran faunal composition. Species diversity index was moderate (1.4–2.5) and evenness index was on the higher side (0.76–0.94). Dominance Index ranged from 26.2 to 64.6. Riparian zone appeared to be the least stressed and most equitable habitat with highest diversity and evenness index and lowest dominance index. Paddy field seemed to be the harshest habitat for damselflies with least diversity and highest dominance index. The present study suggests that community analysis of damselflies can be quite useful in the assessment of the quality of any ecosystem.
