This study experimentally reveals that the response of <i>Daphnia magna</i> Straus and <i>Daphnia pulex</i> plankton ensembles to photostimulation depends on the intensity of the attracting light. This makes it difficult to identify the occurrence and change of pollutant concentration. The large variability in the magnitude of the behavioral response is caused by the nonlinear response of plankton ensembles to the intensity of the attractor stimulus. As the intensity of the photostimulation increases, the variability of the phototropic response passes through increase, decrease, and relative stabilization phases. This paper proposes a modification of the photostimulation method: paired photostimulation involving the successive exposure to two photostimuli of increasing intensity. The first stimulus stabilizes the behavioral response, while the increase in response to the second stimulus makes it possible to more accurately assess the responsiveness of the plankton ensemble. The study demonstrates good reliability and increased sensitivity of this method of detecting changes in environmental toxicity when compared with single photostimulation or traditional bioindication through the survival rate of test organisms.</p>","PeriodicalId":50359,"journal":{"name":"Inland Water Biology","volume":"75 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141153820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quantative characteristics of the bottom communities had been optimally described with the depth ranges. The wave activity significantly affected only the numbers of zoobenthos in the upper 10 m. The openness of the bay had a greater influence on the abundance and biomass of benthos in the range of 1–10 m, presumably taking into account the influence of reflected waves. The biggest numbers and biomass of zoobenthos were in the littoral of the close bay. In the semiclose bay and on the open coast, the maximum abundance of benthic invertebrates shifted in the sublittoral (depth &gt;8 m), where waves affected the benthic communities less. The types of ground significantly affected only the taxonomical composition. In general, the preferential effect on the quantity characteristics of benthos on the rocky slope zone had the features of a shore (openness and depth patterns).

The heterotrophic dinoflagellate <i>Oxyrrhis marina</i> is an excellent model for understanding these processes. In this study, flow cytometry was used to analyze the dynamics of consumption by this predator of its natural prey, the microalga <i>Isochrysis galbana</i> (ISO), and plastic microspheres (MS) of the same size. Furthermore, the effects of the diets containing these components on the swimming speed and movement patterns of <i>Oxyrrhis marina</i> cells were assessed. This was achieved using a computational method for analyzing video recordings of <i>O. marina</i> movement. It was observed from the first minutes of the experiment that the dinoflagellates actively consumed both types of prey, but by the end of the experiment, the number of MS in the medium decreased to a lesser extent, from 4.4 to 2.2 × 10⁵ cells/mL, while <i>Isochrysis galbana</i> cells were almost completely grazed, with their abundance dropping by more than two orders of magnitude, from 4.9 × 10⁵ cells/mL to 2.3 × 10³ cells/mL. Such dynamics were associated with a compensatory increase in the number of microspheres in the medium due to their excretion and repeated phagocytosis by <i>Oxyrrhis marina</i>. Interestingly, the ingestion of plastic microspheres, which led to an increase in dinoflagellate cell size, did not significantly reduce their mobility or impair their locomotion. The ‘unproductive’ consumption of microplastics, which provided no nutritional benefit, resulted in a statistically significant reduction in dinoflagellate abundance compared to controls and the microalgae-fed experiment. This decline was attributed to the high energy expenditure of the population in constantly searching for, phagocytosing, and excreting microspheres. Contrary to expectations, the predators did not abandon this unproductive feeding strategy. Instead, their cell mobility increased over time, exacerbating the situation. These processes could have far-reaching negative implications for the entire food web. Specifically, microplastics 'packaged' by unicellular organisms could be transferred to higher trophic levels, potentially accumulating in mollusks, fish, and larger predators.</p>","PeriodicalId":50359,"journal":{"name":"Inland Water Biology","volume":"2 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141151582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
