“…For N. hyalina and T. glomerata the samples were collected from a single site for each species, in the small available patches they formed when they appeared. N. hyalina disappeared from the selected site during this study in September 2009, however, in further surveys after the collection of samples for the present study, it was found again in other zones of the pond (Rodrigo et al, 2015). T. glomerata, a vernal species, only appeared in winter time and specimens of this species could be collected from January 2010 to the end of the study.…”

“…One of the constructed systems was a pond to try to mimic the formerly abundant springs in the Natural Park, which nowadays have deteriorated due to desiccation and pollution (Rodrigo et al, 2015). After the construction of the pond basin in 2008, it was fed by groundwater sources via a deep artesian borehole from the end of that year.…”

“…Temperature, dissolved O 2 , conductivity, total phosphorus, soluble reactive phosphorus, total nitrogen, chemical oxygen demand and sestonic chlorophyll a were determined in each sampling occasion following standard methods (APHA, 1998; for details see Rodrigo et al, 2015). An integrated water sample was taken from the deepest part of the pond to measure these variables ( Fig.…”

“…This crayfish species has been found to feed preferentially on charophytes rather than higher plants (Cirujano et al, 2004). Also herbivorous waterfowl (mainly coots) feed directly on the charophyte stands and several species of fish have been detected in the pond (Rodrigo et al, 2015). Benthic invertebrates might feed directly on macrophytes but food could also be indirectly supplied by macrophytes which provide space for attached epiphytes (Jaschinski et al, 2011).…”

Quantitative descriptions of foodweb structure based on isotope niche space require knowledge of producers’ isotopic signatures. In freshwater ecosystems charophytes are one of the main components of submerged vegetation and the feeding base for many herbivorous consumers, but knowledge about their organic carbon isotopic signatures is sparse. In this study, the δ13C organic values (and organic %C and %N) of the four species of submerged macrophytes (three charophytes - Chara hispida, Nitella hyalina and Tolypella glomerata - and one angiosperm, Myriophyllum spicatum) growing in a newly created shallow pond were measured monthly over a period of one year, to discern if i) all charophyte species susceptible to being food for consumers and growing in the same waterbody have the same C isotopic composition; ii) the δ13C values of a charophyte species change on a seasonal and spatial scale; iii) the different parts (apical nodes, internodes, rhizoids, reproductive organs, oospores) of a charophyte species have the same isotopic composition. The δ13C, %C and %N values of organic matter in the sediments where the plants were rooted were also measured as well as several limnological variables. The δ13C values for the angiosperm (-13.7±0.7‰) indicated 13C-enrichment, whereas the N. hyalina δ13C values were the most negative (-22.4±0.7‰). The mean δ13C value for C. hispida was -19.0±1.0‰ and -20.7±0.8‰ for T. glomerata. C. hispida δ13C values had a significant seasonal variation with 13C-poor values in the cold season, and slight spatial differences. Statistically significant differences were found between charophyte rhizoids (13C-enriched) and the other parts of the thalli. The δ13C values in the sediments varied throughout time (-13‰ to -26‰). The C content was lower in the charophytes than in the angiosperm and there were no large differences among the charophytes. Charophyte fructifications were enriched in organic C compared to the thalli parts. The study provides an isotopic baseline for further studies for the elucidation of higher trophic-level relationships which are particularly complex in shallow water bodies where interactions between the pelagic and the benthic zones are intricate.

Macrophytes are a good long‐term indicator of quality of aquatic ecosystems and are essential for the proper functioning of the entire lake ecosystem. Submerged vegetation is considered to be indicative of an improvement of the ecological status of these lakes. Here, we analyzed the distribution, structure, and diversity of vegetation communities in four eutrophic water bodies (postglacial lakes: Sławskie and Uzarzewskie and man‐made lakes: Maltański Reservoir and Turawa Średnia Reservoir) after the application of restauration and protections measures. The restoration measures included biomanipulation, phosphorus inactivation, hypolimnion aeration, or injection of nitrate‐rich waters to the hypolimnion. All of them were sustainable and did not cause drastic changes in the ecosystem. Between 9 and 17 macrophyte communities were found in the examined water bodies. The largest effects were observed after the simultaneous use of three lake restoration techniques which led to the appearance of 17% charophytes. Pronounced effects leading to the higher contribution of elodeids to the macrophyte community were achieved in the lake in which two methods were applied. Least effective was the method focused on hypolimnion restoration in a small lake, which did not cause the reappearance of submerged vegetation. Spontaneous recovery achieving good status is also possible in a large lake in case of applying the thorough conservation measures. An intensive growth and diversity of macrophytes was a result of the improvement in the water quality as a consequence of undertaken protective activities and/or restoration measures. However, the re‐colonization of submerged macrophytes during restoration process is not obvious and the feed‐back mechanisms may delay a response of the ecosystem. The vegetation of the studied lakes was unstable, showing high variability in individual years of research, which indicates that these ecosystems are still under reconstruction and not reach equilibrium state yet.
