Plankton Community Structure

The influence of filter-feeding bivalves on plankton communities, nutrients, and water quality in a given aquatic ecosystem is so profound that they can be considered ecosystem engineers. In a 70-day mesocosm experiment, we tested the hypothesis that Corbicula fluminea would change plankton community structure by reducing small zooplankton and large phytoplankton and improve water quality by reducing nutrients. We monitored levels of nitrogen and phosphorus, organic suspended solids (OSS), and light at the sediment surface. Within the plankton, phytoplankton biomass (as Chl a, >0.45 μm), the biomass of microphytoplankton (>20 μm), nanophytoplankton (2–20 μm), picophytoplankton (0.2–2 μm), and zooplankton were determined. Compared with the controls, C. fluminea reduced the abundance of rotifers and the biomass of phytoplankton, and picophytoplankton, thereby modifying the plankton community structure. We did not observe reductions in TN and TP concentration, but OSS concentrations were reduced, and light intensity at the sediment surface was increased as a result of the improved water transparency. Our research shows that colonization by C. fluminea may modify plankton community structure and improve water quality of eutrophic shallow lakes, shedding further light on the ecological roles of filter-feeding bivalves in aquatic ecosystems.

Plankton Community Structure

Minapadi is an integration of rice cultivation with fish breeding in one location. This research was conducted in the village of Talagasari, District Garut Kadungora because this area is thought to have nutrient elements in the form of specific micro and macro minerals that are good for agriculture and fisheries. Planktons are microscopic organisms that form an important link in the life of aquatic organisms. This research aimeds to analyze the quality of water, mineral composition and its effects on plankton community structure in minapadi. The research method used was purposive sampling. Plankton relationship with water quality and dissolved minerals were analyzed using a Canonical Correspondence Analysis (CCA). Sampling was done 6 times in the period May 20 - July 25, 2018. Research shows that there are 31 orders of plankton consisting of 26 orders of phytoplankton and 5 order of zooplankton. Phytoplankton diversity index and dominance over their respective research ranged from 0,5149 to 0,8797 and 0,1203 to 0,4851, while for zooplankton from 0 to 0,8 and from 0,2 to 0,1. The water quality parameters measured primarily by temperature, DO, pH, nitrates, phosphates, ammonia qualify recommended PP 82 2001, third class. There is a concentration of dissolved minerals that exceeds the normal condition nitrates, phosphates, ammonia qualify recommended PP 82 2001, third class. There is a concentration of dissolved mineral exceeds the normal condition K, S, Si, Ca, Fe, Mn, Cu, and Cl, which led to the dominance of the phylum Euglenophyta, Bacillariophyta, and arthropods.

ABSTRAKMengingat peranan zooplankton dalam ekosistem perairan sangat penting, maka dilakukan penelitian dengan tujuan untuk menganalisis struktur komunitas zooplankton yang meliputi jenis, kelimpahan, dan indek ekologi, dan  kaitan  distribusi zooplankton dan kualitas perairan di Perairan Kabupaten Lombok Utara. Pengumpulan data dirancang dengan sistem informasi geografis (SIG) pada 23 stasiun pengamatan yang ditentukan dengan teknik acak sederhana.  Hasil penelitian menunjukkan bahwa jenis dan kelimpahan zooplankton yang ditemukan di Perairan Kabupaten Lombok Utara cukup bervariasi dengan jumlah genus  sebanyak 9 yang terbagi  dari  5 kelas.  Berdasarkan perhitungan indeks ekologi menunjukkan bahwa struktur  komunitas zooplankton dalam kategori perairan yang kurang stabil. Kelimpahan dan indeks ekologi zooplankton  dipengaruhi oleh kondisi lingkungan (fisik-kimia) perairan antara lain  kecerahan, pH dan oksigen terlarut. Kata kunci : zooplankton,  struktur komunitas, kualitas perairan, kelimpahanABSTRACTConsidering that the role of zooplankton in aquatic ecosystems is very  important, research is carried out with the aim of analyzing zooplankton community structure which includes the type, abundance, and ecological index, and the relation of zooplankton distribution and water quality in North Lombok Regency Waters. Data collection was designed with a geographical information system (GIS) on 23 observation stations that were determined by simple random techniques. he results of this study indicate that the type and abundance of zooplankton found in the waters of North Lombok Regency are quite varied with the number of genus as many as 9 which are divided into 5 classes. Based on the calculation of the ecological index shows that the zooplankton community structure is in the category of less stable waters. The abundance and ecological index of zooplankton is influenced by the environmental (physical-chemical) conditions of the waters including brightness, pH and dissolved oxygen. Keywords: zooplankton, community structure, water quality, abundance
