“…For example, decomposition of the floating macrophyte Hydrocharis morsusranae was inversely related to its Cd, Cu, and Ni contents, but was positively related to its Ca, Fe, and Mg contents. 82 In addition to mineral elements, polyphenolic substances in plant litter play a role in the decomposition process. They can interact with plant proteins, forming complexes that resist decay or counter degradation-related enzymes, thereby rendering them inactive.…”

Aquatic macrophyte litter decomposition (AMD) is essential for material cycling and energy flow in freshwater ecosystems. This decomposition process encompasses several stages, each demanding the involvement of specific organisms. As interspecific interactions evolve, so does the process of decomposition. However, a comprehensive review specifically highlighting the central roles and intricate dynamics of these interspecific interactions in the decomposition process is notably lacking. Therefore, we herein introduce the stages of AMD and, in conjunction with interspecific relationships, delve into the impact of biotic and abiotic factors and litter quality on AMD. After reviewing the literature, it becomes evident that almost every stage of litter decomposition requires the participation of decomposer organisms. Moreover, the decomposition capabilities vary significantly among different decomposer organisms, with each exhibiting unique sensitivities to environmental shifts. Therefore, understanding these interspecific relationships is pivotal for interpreting the current global shifts in AMD. However, due to monitoring and statistical constraints, previous discussions of AMD have largely focused on a few decomposer organisms with limited exploration of wider decomposer communities. This review emphasizes the need to strengthen research on interspecific relationships within the decomposer community, thereby supporting future investigations into the mechanisms that drive elemental cycling in freshwater ecosystems.

“…The studies conducted so far in natural aquatic ecosystems [GAŁCZYŃSKA, BEDNARZ 2012;POLECHOŃSKA, DAMBIEC 2014;POLE-CHOŃSKA et al 2017;POLECHOŃSKA, SAMECKA-CYMERMAN 2015;SKWIERAWSKI, SKWIERAWSKA 2013] show the possibility of occurrence of H. morsus-ranae in waters contaminated with metals, including heavy metals. The results confirming the accumulation of substantial amounts of metals in the plant's tissues as well as high efficiency of such accumulation in defined environmental conditions, support including H. morsus-ranae to a group of bioindicators of waters contaminated with metals [GAŁCZYŃSKA 2012;POLECHOŃSKA, DAMBIEC 2014;POLECHOŃSKA et al 2017;POLECHOŃSKA, SAMECKA-CYMERMAN 2015]. Chlorophyll content is one of the parameters which may indicate the viability of a bioindicator when conducting studies.…”

“…Due to high phytoremediation potential of H. morsus-ranae and quick decomposition time of the plant combined with the release of the elements accumulated in the leaves to water [GAŁCZYŃSKA 2012;POLECHOŃSKA, SAMECKA-CYMERMAN 2015;, the possibility of using the plant for phytoremediation of waters contaminated with metals are limited mainly by the length of application time.…”

Anthropogenic pollution leads to increased concentrations of metals in the freshwater and macrophyte. Aquatic plants substantially contribute to the structure, function as well as and service provision of aquatic ecosystems. Our microcosm experiments were to test the possibility of the physiological response of Hydrocharis morsus-ranae to metal (Cd, Pb, Cu, Zn, Mn, Fe at three level of concentration) contaminated waters. Biomass was analysed at the beginning and at the end of the experiment. At the same time contents of photosynthetic pigments in leaves were estimated spectrophotometrically. We found that this macrophyte had the ability to grow in contaminated waters, but the effects of high concentration of isolated metals in water will indicate changes consisting in the disappearance of a significant part of biological populations were which manifested in alteration of the content of photosynthetic pigments as well as this plant's growth. We show that generally stress of Zn and Cu influenced the drop of dry biomass which was connected with a positive correlation between the amount of dry biomass and the content of chlorophyll a and carotenoids, or only carotenoids, respectively. The highest stress of Pb and Fe (third concentrations of these metals) also influenced the drop of biomass. We concluded that none of Cd concentrations were toxic to this plant, but the effect of Mn stress was not unequivocal. Moreover, plant growth was stimulated by low Fe concentrations (first concentration) demonstrating the hormesis effect. When plants were exposed to this metal, there was no evidence of damage to the photosynthetic processes.
