“…If no other macrophytes establish during the senescence of P. crispus the water may become dominated by phytoplankton and risks being shifted into a turbid state. This might further impair benthic food webs, a key pathway in shallow water bodies, which has largely been ignored (Puche et al, 2021; Vadeboncoeur et al, 2003).…”

Submerged macrophytes play a key role in maintaining a clear‐water phase and promoting biodiversity in shallow aquatic ecosystems. Since their abundance has declined globally due to anthropogenic activities, it is important to include them in aquatic ecosystem restoration programs. Macrophytes establishment in early spring is crucial for the subsequent growth of other warm‐adapted macrophytes. However, factors affecting this early establishment of submerged macrophytes have not been fully explored yet. Here, we conducted an outdoor experiment from winter to early spring using the submerged macrophytes Potamogeton crispus and Vallisneria spinulosa to study the effects of shading, nutrient loading, snail herbivory (Radix swinhoei), and their interactions on the early growth and stoichiometric characteristics of macrophytes. The results show that the effects strongly depend on macrophyte species. Biomass and number of shoots of P. crispus decreased, and internode length increased during low light conditions, but were not affected by nutrient loading. P. crispus shoot biomass and number showed hump‐shaped responses to increased snail biomass under full light. In contrast, the biomass of the plant linearly decreased with snail biomass under low light. This indicates an interaction of light with snail herbivory. Since snails prefer grazing on periphyton over macrophytes, a low density of snails promoted growth of P. crispus by removing periphyton competition, while herbivory on the macrophyte increased during a high density of snails. The growth of V. spinulosa was not affected by any of the factors, probably because of growth limitation by low temperature. Our study demonstrates that the interaction of light with snail herbivory may affect establishment and growth of submerged macrophytes in early spring. Macrophyte restoration projects may thus benefit from lowering water levels to increase light availability and making smart use of cold‐adapted herbivores to reduce light competition with periphyton.

“…Both phytoplankton and zooplankton samples were taken with a sampler from the shores at a depth of approximately 25 cm. We include in our "plankton" analyses all the species found in the samples collected from the water column, including the benthic organisms (which were also present in these kinds of samples since the wetland is a shallow habitat with vegetation) because they are a relevant part of the aquatic network (Rojo et al 2017;Puche et al 2021). Phytoplankton samples were xed with lugol; individuals of each population were taxonomically identi ed, classi ed, counted and measured to obtain body-size (µm 3 ) as well as population and total biovolume (mm 3 /l; Rodrigo and Segura 2020).…”

“…Furthermore, inside the CWs, vegetation and the proximity of the sediment contributed, along with benthic biota, to the community found in the water column. This combination allows a very effective plankton-benthos network to be established in which benthic organisms play a central role in spreading the effects of disturbances to the community (Puche et al 2021). In conclusion, we have seen how CWs with different features have been bene cial to the environment by improving the plankton communities.…”

“…These mainly benthic taxa can migrate to the water column (Round and Eaton 1966) and are related to mixotrophic feeding (Jones 2000). In this way, their presence and biomass represent a considerable energy input to the plankton communities from the microbial food web (Calero et al 2015), acting as a bypass of carbon ux toward the autotrophic food web (Medina-Sánchez et al 2004; Puche et al 2021). With respect to zooplankton, the rotifer/cladoceran richness ratio decreased in 72% of the samplings over time from the Inlet to the Outlet (Table S1).…”

“…Focusing on the community composition offers information about water-quality-indicator species and the existence of certain key roles in the wetland's trophic web (Declerck et al 1997;). This approach can consider that water quality improves within a CW if the plankton composition changes towards a higher diversity of roles, which allows a more e cient transference of energy and matter, and a higher stability in the food web (Puche et al 2021). Despite these facts, there are still few studies on the planktonic community of CWs (Luyiga and Kiwanuka 2003;Chen et al 2011;Li et al 2014;Castro-Castellon et al 2016).…”

Constructed wetlands (CWs) are created to enhance wildlife and improve water quality. These services are especially relevant when the CWs are linked to a natural wetland. The CWs effectiveness in improving water quality has been demonstrated, but their role in enhancing the plankton biodiversity discharged into the wetland has not. To assess this, we analysed the plankton community of three structurally different CWs created within a protected Mediterranean wetland (Albufera de València Natural Park) over two years (2014–2015). We hypothesize that alpha-diversity in the inlet communities (a species mix from anthropically disturbed environments) will be higher than those from inner and outlet sites where natural assembly processes occur, and the beta-diversity of the Natural Park will increase due to the different communities found within and between the CWs. The first hypothesis was only partially supported: in two CWs the diversity decreased due to the loss of chlorophytes and cyanobacteria, or the dominance of large copepods or cladocerans. However, when organisms in the inlet bloomed, the emerging assemblages within the CW increased the diversity, as occurred in the third CW. The species of the resulting communities were indicative of improved water quality. The second hypothesis was also proved: the CWs contributed to beta-diversity as they functioned as generators of communities. Within the CWs, vegetation and sediment supplied benthic species to the water column. Communities being discharged into the wetland were much more dissimilar than those arriving in the CWs. Therefore, the wetland assemblage beta-diversity increased thanks to the diversity of CWs.

The effectiveness of constructed wetlands (CWs) created to improve water quality has been demonstrated. However, their role in enhancing biodiversity, such as in plankton communities, is still understudied. To assess this, we analysed, over two years, the plankton of three structurally different CWs which are intermediaries between low-quality waters and a protected Mediterranean wetland (Albufera de València Natural Park). We estimated the alpha-diversity of each CW and the beta-diversity among their different sectors. In two CWs, the diversity decreased as water flowed from the Inlet (a species mix from anthropically disturbed environments) to the Outlet, due to natural assembly processes. In the other CW, as it received water dominated by a few species, the emerging assemblages increased the diversity. Moreover, comparing the three CWs, the most divergent communities were those in the outlets (due to the emergence of exclusive species, biovolume differences, etc.). Therefore, they contributed to beta-diversity as they acted as generators of communities, which were characterized by the loss of cyanobacteria and chlorophytes, the dominance of large copepods or cladocerans and the presence of unshared species. We emphasize the importance of having structurally and functionally different CWs to enhance biodiversity and improve biological water quality in natural parks.
