ABSTRAKEmpat belas sampel air laut diamati komunitas planktonnya. Sampel diambil di kawasan perairansuaka perikanan Gili Ranggo Teluk Serewe Lombok Timur, menggunakan jaring plankton bermatajaring 20 mikron. Pengamatan dan identifikasi spesies plankton dilaksanakan di LaboratoriumBiologi Dasar UPT-MIPA Universitas Mataram. Kepadatan setiap jenis fitoplankton danzooplankton ditentukan berdasarkan jumlah individu per liter air. Indeks keanekaragaman jenisfitoplankton dan zooplankton ditentukan berdasarkan “Indeks Shannon-Wienner”. Selanjutnya,hubungan kuantitatif antara fitoplankton dan zooplankton ditentukan dengan menggunakan“Korelasi Jenjang Spearman”. Total plankton teridentifikasi adalah 123 spesies meliputi 82 spesiesfitoplankton dan 41 spesies zooplankton. Komunitas fitoplankton didominasi oleh spesies dari familiBacillariophyceae (diatom), yaitu sebanyak 75 spesies. Tujuh spesies lainnya adalah anggota darifamily Dinophyceae (dinoflagellata). Sedangkan komunitas zooplankton di perairan suaka perikananGili Ranggo Teluk Serewe Lombok Timur didominasi oleh spesies dari genus Tintinnopsis. Nilaiindeks keanekaragaman jenis fitoplankton dan zooplankton termasuk dalam kategorikeanekaragaman sedang. Hubungan kuantitatif fitoplankton dengan zooplankton pada tarafsignifikansi 5% dengan tujuh pasang jenjang, diperoleh hasil rs Hitung lebih kecil dari rs Tabel (0,643 <0,857), artinya bahwa tidak terdapat korelasi positif antara fitoplankton dan zooplankton.Kata-kata kunci: kuantitatif, fitoplankton, zooplankton, suaka perikananABSTRACTFourteen of 50 ml volume bottle plankton net collecting samples were observed for the community ofplankton (phytoplankton and zooplankton) of the fish sanctuary of Gili Ranggo (Serewe Bay) eastLombok. Samples observation and plankton identification were done at the Laboratory of Biology,UPT-MIPA University of Mataram. Density or abundant of each plankton species was determinedbased on the number of individual per liter. Shannon-Wienner Diversity Index was applied fordetermining the species diversity index. Furthermore, the “Spearman Correlation” was also appliedfor analyzing the quantitative correlation of phytoplankton and zooplankton. Total of 50 generacontaining 123 species of plankton were fully identified. This study fully identified of 82 species ofphytoplankton, the members of both Dynophyceae (dinoflagellates) and Bacillariophyceae (diatom)families, and 41 species of zooplankton. The fish sanctuary of Gili Ranggo, Serewe Bay wasdominated by the member of Bacillariophyceae family. The 41 species of zooplankton is dominatedby the species of the genus Tintinnopsis. Both phytoplankton and zooplankton communities have ahigh species diversity index category. Quantitative correlation of phytoplankton and zooplankton ata seven pair and significant of 5%, is rs count less than rs Table (0.643 < 0.857). This means, there wasno possitive correlation between the present of phytoplankton and zooplankton communities.Key Words: quantitative, phytoplankton, zooplankton, fish sanctuary

The diversity of freshwater zooplankton is still little known in Mexico, particularly in reference to insular zooplankton communities. Diaptomid copepods (Crustacea: Copepoda: Calanoida) are a widespread group worldwide, and Mexico harbours high diaptomid diversity. Based on a recent sampling of freshwater zooplankton on a Caribbean Island of Mexico, we present the first record of a diaptomid copepod from an island freshwater ecosystem. It shows the well-known tendency of Neotropical diaptomids to have restricted distributional patterns and high levels of endemism. The species recorded, Mastigodiaptomus ha (Cervantes-Martínez, 2020) appears to have a restricted distribution in the Yucatan Peninsula (YP), and the island as well. In order to explore potential differences between the island and continental populations of this species, its phenetic and genetic diversity was analysed by performing morphological comparisons and also by exploring differences of the habitat conditions and genetic sequences (CO1 gene). Our analysis revealed a low (average = 0.33%) genetic divergence between both populations; likewise, both the morphology and habitat conditions closely resemble each other in these two populations. The low genetic divergence between the continental and island populations of M. ha suggests an early common origin of the species in the geological history of the YP.

Abstract The paper presents the results of an investigation of physical-chemical features of water as well as rotifer and crustacean abundance and diversity measures, relating to the taxonomic richness and species diversity index, in three lobelia lakes differing in trophic status and morphometric features. The main purpose of this study was to establish the diversity of zooplankton communities in the open water area of lobelia lakes, including extracting species common for each lake and also to find environmental predictors which are responsible for the development of zooplankton communities. Despite the fact that the three studied lakes are of the same origin, located in the same vicinity and have generally similar environmental factors, zooplankton community structure revealed a great variation in reference to species diversity (only ca. 20% of the species were common for all lakes) and particularly in inhabiting species. Obrowo Lake had the most diverse assemblages of both rotifers and crustaceans compared to Modre and Pomysko lakes. In the taxonomic structure species that are rare for the Polish fauna, such as e.g. Holopedium gibberum and Heterocope appendiculata, occurred. Even though the examined lobelia lakes are ecosystems that undergo varying human-induced impacts, they still remain taxonomically very variable aquatic ecosystems, containing rare species of very high ecological status. The observed symptoms of deterioration of water quality, reflected in the zooplankton biocoenotic features, showed that the best conditions were attributed to Obrowo Lake in comparison with the two remaining lakes – Modre and Pomysko. Total nitrogen and chlorophyll a concentration were decisive for the distribution of zooplankton species in Pomysko and Obrowo lakes, while in case of Modre lake water reactivity and conductivity were of higher impact.
