The last few decades have seen a dramatic increase in water pollution due to various types of waste generated by human activity. These include plastic and glass accumulating in the shore area of lakes and oceans. These substrates may be colonized by various groups of aquatic organisms. Little is known of the trophic interrelationships between micro- and macroorganisms colonizing plastic (PB) and glass bottles (GB). Therefore, the main objective of the present study was to determine the taxonomic composition and abundance of micro- and macroorganisms colonizing artificial, anthropogenic substrates, the trophic relationships between the organisms colonizing these substrates, and the influence of the physicochemical properties of the water on the formation of such assemblages. Studies of micro- and macroorganisms were carried out on the surface of PB and GB in a eutrophic retention basin. Both the species richness and abundance of microorganisms and metazoa were found to be determined by the type of substrate colonized as well as by the physicochemical properties of the water (primarily the content of total organic carbon and biogenic compounds). Furthermore, the trophic structure of microbial assemblages demonstrated seasonal variability. In spring, the substrates were colonized by typical bacterivorous ciliates, whereas in the following seasons there was a larger share of omnivorous species (ciliates and rotifers). This may indicate that the accumulation of various types of anthropogenic waste, in the present case GB and PB, may contribute to changes in the matter and energy cycle, including the carbon cycle, in various microhabitats of aquatic ecosystems.

瓶子上的缩影:保留容器中塑料和玻璃基质定殖的实验测试:

在过去的几十年中,由于人类活动产生的各种废物,水污染急剧增加。其中包括堆积在湖泊和海洋沿岸地区的塑料和玻璃。这些底物可能被各种水生生物定殖。微生物和微生物在塑料(PB)和玻璃瓶(GB)上的营养相互关系鲜为人知。因此,本研究的主要目的是确定定居在人工,人为底物上的微生物和大微生物的分类学组成和丰度,定居在这些底物上的生物之间的营养关系以及水对水的理化性质的影响。这种组合的形成。在富营养化滞留池中对PB和GB的表面进行了微生物和大微生物的研究。发现微生物和后生动物的物种丰富度和丰富度都取决于所定殖的底物类型以及水的理化特性(主要是总有机碳和生物化合物的含量)。此外,微生物组合的营养结构显示出季节性变化。在春季,基质被典型的细菌性纤毛虫定殖,而在随后的季节中,杂食性物种(纤毛虫和轮虫)的份额更大。这可能表明,各种类型的人为废物(在当前情况下为GB和PB)的积累可能有助于物质和能量循环(包括碳循环)的变化,
