The Prediction of Plankton Diversity and Abundance in Mangrove Ecosystem

Abstract

The abundance of phytoplankton and zooplankton have correlation with mangrove conditions in coastal area. The mangrove degradation give negative impact for abundance and diversity phytoplankton and zooplankton. The research aimed to analysis and construct prediction model of abundance and biodiversity of phytoplankton and zooplankton in mangrove ecosystem. The research used the transect method (to determine mangrove density), filtering method (to analyze abundance of phytoplankton and zoopankton) and statistical method (to develop estimation modeling of plankton abundance). The results showed that (1) the mangrove density between 250 trees/Ha - 1250 trees/Ha (2) the phytoplankton abundance were 10.675 Indv/L (in mangrove rarely) - 24.290 indv/ L (in mangrove high density), (3) the zooplankton abundance were 261 Indv/L (in mangrove rarely) - 2.204 indv/L (in mangrove high density) (4) The modelling analysis showed that (1) the phytoplankton abundance (y) = 0.0303 x2 - 22.059 x + 13004 and (2) the zooplankton abundance (y) = 0.0057x2 – 5.39 x + 1458.2, with x = mangrove densityKeywords: phytoplankton and zooplankton, mangrove density, abundance, estuary and lagoon

The Mangrove Density, Diversity, and Environmental Factors as Important Variables to Support the Conservation Program of Essential Ecosystem Area in Muara Kali Ijo, Pantai Ayah, Kebumen

“…The potential data on mangrove density showed that the mangrove ecosystem in Muara Kali Ijo is regenerating (Hilmi et al 2015;Nur and Hilmi 2021). Mangrove density, domination, and regeneration of mangrove species have a positive impact on the potentials of plankton (Andriyani et al 2020;Hilmi et al 2020), other micro and macro-organisms (Su et al 2012;Yin et al 2018), land animal habitats, other organisms, and birds (Putra et al 2019;Wolswijk et al 2020).…”

Evaluation of Mangrove Water Quality in Pancer Cengkrong, Trenggalek and Sine, Tulungagung, East Java, Indonesia Using Phytoplankton as Bioindicators

“…The low value of DO in Sine is due to the influence of anthropogenic activities such as tourist attractions, and settlements that produce a lot of organic and inorganic waste from the disposal of the surrounding population. Meanwhile, the high DO value at Cengkrong 2008-2009 was due to the location being far from anthropogenic activities and land degradation so that mangrove growth was optimal and capable of maximal remediation of organic matter (Hilmi et al, 2020;Samara et al, 2020). Dissolved oxygen in water is used by aquatic organisms for cell metabolism through the respiration process so that energy is formed (Singh et al, 2017) The BOD values obtained showed significant differences ranging from 2.64-5.96 mg/L (Table 5).…”

“…As they are located at transition areas of inland and seawater, mangroves are affected by tides. Mangroves adapt to survive in this vulnerable environment by having high adaptability to salt (halophytes), low oxygen levels, and unstable soils, and experiencing an inundation cycle due to tides (Hilmi et al, 2020). Mangroves have important roles in maintaining and protecting the coast from sea waves, as a storage of carbon stock, and as a habitat for other organisms (Saifullah et al, 2016).…”

“…Phytoplankton community structure and diversity can be measured as bioindicators of aquatic ecosystem health. Phytoplankton is important as primary producers and involve in nutrient cycles that support growth and survival of organisms in the mangrove ecosystem (Hilmi et al, 2020;Khumaidi et al, 2020). In addition, phytoplankton float passively in the waters, their life cycle is short and they respond to environmental changes quickly which makes them a good bioindicator of water quality (Hilmi et al, 2020).…”

One way to use phytoplankton as a bioindicator is to use a biotic index such as Tropic Diatom Index (TDI) and Pollution Tolerance Value (%PTV).…”
