Relationship Between Macroinvertebrate Diversity With Elements C and N in The Mangrove Forest of Wonorejo Surabaya

Abstract

Conservation of mangrove forests can be supported by constantly analyzing the interactions of organisms in these habitats. Mangrove plants require C and N nutrients in high concentrations. Based on these nutrient requirements, it is hypothesized that there is also a correlation between the species and diversity of macroinvertebrates in mangrove forests with C and N nutrients. In this study, randomized purposive sampling was conducted to obtain macroinvertebrate species. The physical and chemical properties of soil and water were also measured in this study. The specimens obtained were then identified. In addition, an analysis of the content of C and N in soil and water samples was also carried out. Dominance and diversity analysis as well as statistical analysis were carried out to determine certain species that were resistant to a high concentration of C and N. In this current study 32 species were identified. The highest species diversity index was at station 1 (2.868) and the highest dominance index was at station 2 (0.182). Based on the test results for the highest C nutrient at station 3 (2.055) and N at station 4 (0.129). The relationship between macroinvertebrate diversity with elements C dan N is inversely propostional. The higher the diversity of macroinvertebrate, the lower the elements C and N.
