“…Mixotrophy is the occurrence of phagotrophy and phototrophy in the same organism. A phagotroph consumes phototrophs, such as flagellates, and leaves them intact, thus deriving organic matter from them [72,73]. Although most ciliates are heterotrophic, many species are mixotrophic [74].…”

Peatlands are extremely valuable ecosystems of enormous biological diversity, mainly due to their specific geological and hydrological conditions. One of the most important threats facing these habitats is overgrowth resulting from intensifying succession processes. Due to the fact that peatlands are endangered or vanishing, attempts are made to restore their original natural assets. The aim of the present study was to determine the effect of active conservation of peatland ecosystems, in the form of removal of birch trees, on communities of ciliates. The subject of the research was the Durne Bagno peat bog, located in Polesie National Park in eastern Poland. Analysis of the results of long-term research (nine years) showed that active conservation measures affect the physical, chemical, and hydrological properties of peatlands. In the habitat where birch trees were cut down, the water level, temperature, and chlorophyll a concentration in the vast majority of cases were higher than in the area with Betula L. Changes in habitat conditions are reflected in the taxonomic composition and abundance of ciliates. In the habitat from which birch trees were removed, ciliate abundance was higher than in areas where birch remained. The total number of taxa in the habitats was the same, but there were seasonal differences. The most taxa were recorded in spring and summer and the fewest in autumn. Thus, analysis of the results indicates that ciliates are an appropriate indicator group of species for biomonitoring of peatland restoration.

“…The canonical biplot analysis (Figure 4) shows that environmental factors (physical and chemical) had a greater influence on the abundance and composition of phytoplankton in the three salt ponds than predatory factors or zooplankton. Although Brebes and Sampang salt ponds are characterized by the dominance of Didinium sp., a carnivorous zooplankton type, Tuban salt ponds are characterized by Tintinnopsis sp., which has tendencies as an herbivore (Camarillo and Zaragoza 2021). It is widely known that zooplankton as a predator impacts plankton composition.…”

Abstract. Susilowati R, Bengen DG, Krisanti M, Januar HI, Rusmana I. 2023. Temporal and spatial distribution of plankton community in three Indonesian salt pond environments. Biodiversitas 24: 1833-1844. Plankton is a biological community that plays an important role in biological systems during salt crystallization. The correlation between plankton communities and water quality parameters was examined in three salt pond center areas (Brebes, Tuban, and Sampang). The values of nutrient content in Brebes were higher compared to other locations, with phosphate (5.38-5.66 mg/L), nitrate (0.17-0.74 mg/L), nitrite (0.07-0.1 mg/L), and total organic matter (0.03-0.07 mg/L). Based on multivariate analysis, there was no significant difference in the abundance of plankton among the three salt pond locations. Furthermore, Spearman's correlation test indicated a negative correlation (Sig<0.05) between salinity and the abundance and diversity of plankton. The highest abundance of phytoplankton (127,721±11.227 cells/L) and zooplankton (3,339±391 idvs/L) was found in the Brebes. Phytoplankton from the genera Bacillarophyceae Bacillarophyceae was dominant in the three locations. In Brebes and Sampang, the dominant classes of zooplankton were Litostomatea, whereas, Oligotrichea was dominant in Tuban, The phytoplankton community structure has a diversity index (H') of 0.91-2.05, and Evenness index (E) ranging from 0.12-0.20, and a dominance index (C) showing a level of 0.14-0.34. At the same time, the zooplankton community has a diversity index (H') of 0.81-1.64, an evenness index (E) that has ranged from 0.18-0.22, and a dominance index (C) that has ranged from 0.03-0.20. The research examines plankton communities in varying salinity and their response to environmental changes. This data is useful for managing salt pond productivity, vital for sustainable and high-quality salt production.

“…A commonly identified effect of eutrophication is 'biotic homogenization'. This term refers to an increase in the repeatability of species composition in different places or samples and is determined quantitatively by means of a dissimilarity index [12,13].…”

Global climate change and increasing human impact are the main factors intensifying eutrophication of peatland ecosystems. Due to the high sensitivity of certain groups of microorganisms, they can serve as indicators of the degree of eutrophication and thereby provide much important information for assessment of the state of peatland ecosystems. However, there is still little knowledge of how changes in the fertility of the environment can affect the microbiome of carnivorous plants in these ecosystems. This study was conducted to verify the following hypotheses: (1) the microbiome of carnivorous plant traps reflects the trophic status of the habitat; (2) an increase in the concentration of biogenic compounds causes a greater increase in the size of microbial communities in the aquatic environment than in the traps. An experiment was carried out in laboratory conditions to determine the effect of simulated eutrophication on the microbiome of Utricularia vulgaris L. An experimental increase in habitat fertility caused an increase in the abundance of bacteria, flagellates, testate amoebae, ciliates, and rotifers, while a decrease in abundance was observed for crustaceans. The increase in the concentration of biogenic compounds also modified the taxonomic composition of communities of microorganisms and small metazoa as well as the strength of trophic relationships; as the trophic level increased, the relationships between bacteria and heterotrophic flagellates; bacteria and testate amoebae; and bacteria and ciliates became stronger.
