“…Lawton et al ., (2017) identify the cosmopolitan freshwater macroalgae genus Oedogonium as an ideal candidate for open pond systems, as it is resilient, competitively dominant and has biomass productivities comparable with microalgae 44 . Sakharova et al ., (2018) have illustrated that Oedogonium is resistant to the grazing of zebra mussels 45 and so therefore a coculture system in which zebra mussels remove competing microalgae species, reducing competition for light and nutrients, may help to improve Oedogonium yields further.…”

Synthetic Ecology is a novel concept describing the design of de novo ecological communities for a designated purpose. This study is a proof of concept for harnessing Synthetic Ecology in expanding the scale of commercially relevant micro algae ( Chlorella vulgaris ) cultivation using stable Synthetic Ecologies in open environments as opposed to vulnerable monocultures. We focused on whether the grazing activity of zebra mussels ( Dreissena polymorpha ) would result in a consistent, and commercially favourable, dominance of Chlorella in cultures that were also inoculated with a competing and potentially invasive cyanobacteria ( Synechocystis sp. PCC6803 ). The key result of this study was that in axenic mixed species co-cultures, zebra mussels had a significantly greater negative effect on Synechocystis cell numbers than Chlorella (P < 0.0001). The zebra mussels’ putative preference for Synechocystis over Chlorella suggests they could be used to maintain the dominance of Chlorella in outdoor cultivation systems prone to contamination by invasive cyanobacteria.

“…This also reduces nutrients and energy availability for planktivores, resulting in smaller young-of-the-year fish (Hansen et al, 2020). Improved light conditions and increased nutrient availability in the benthos also have led to an increase in filamentous algae and periphyton after zebra mussel establishment (Lowe and Pillsbury 1995;Sakharova et al, 2018). In some instances, zebra mussel densities have become high enough to reduce dissolved oxygen (DO) concentrations in the water column (Caraco et al, 2000;Effler et al, 2004).…”

Phytoplankton response to water quality threats in Midwest reservoirs

Harmful cyanobacterial blooms and invasive species threaten water quality. These threats are expected to worsen in the future, emphasizing the need for creative management solutions and a thorough understanding of their impacts. The objective of this dissertation is to investigate the influence of light on biomass and community composition of phytoplankton with the hypothesis that light will have an impact, regardless of nutrients and grazing. We investigate a novel geoengineering approach designed to control cyanobacteria by reducing light. We demonstrate that daily application of glacial rock flour, a fine particulate that floats on the water's surface, reduces light by half and results in up to a 78 percent decrease in cyanobacterial biovolume. We also look at the accumulation of microcystin in the tissues of bluegill and largemouth bass. Microcystin is higher in bluegill, likely because they feed from lower trophic levels. It is also higher in spring and decreases throughout the year, suggesting that time of the year might be an important consideration for microcystin fish consumption advisories. We also find that invasive zebra mussels are not causing an increase in water clarity in MO reservoirs like they are in natural, northern latitude lakes. This could be because reservoir conditions are suboptimal for zebra mussels, thus preventing them from reaching high densities. Understanding how aquatic resources have responded to stressors in the past enables us to predict how they will respond to changes in the future.

The introduction of invasive species has become an increasing environmental problem in freshwater ecosystems due to the high economic and ecological impacts it has generated. This systematic review covers publications from 2010 to 2020, focusing on non‐native invasive freshwater bivalves, a particularly relevant and widespread introduced taxonomic group in fresh waters. We collected information on the most studied species, the main objectives of the studies, their geographical location, study duration, and type of research. Furthermore, we focused on assessing the levels of ecological evidence presented, the type of interactions of non‐native bivalves with other organisms and the classification of their impacts. A total of 397 publications were retrieved. The studies addressed a total of 17 species of non‐native freshwater bivalves; however, most publications focused on the species Corbicula fluminea and Dreissena polymorpha, which are recognised for their widespread distribution and extensive negative impacts. Many other non‐native invasive bivalve species have been poorly studied. A high geographical bias was also present, with a considerable lack of studies in developing countries. The most frequent studies had shorter temporal periods, smaller spatial extents, and more observational data, were field‐based, and usually evaluated possible ecological impacts at the individual and population levels. There were 94 publications documenting discernible impacts according to the Environmental Impact Classification for Alien Taxa (EICAT). However, 41 of these publications did not provide sufficient data to determine an impact. The most common effects of invasive bivalves on ecosystems were structural alterations, and chemical and physical changes, which are anticipated due to their role as ecosystem engineers. Despite a considerable number of studies in the field and advances in our understanding of some species over the past decade, long‐term data and large‐scale studies are still needed to understand better the impacts, particularly at the community and ecosystem levels and in less‐studied geographic regions. The widespread distribution of several non‐native freshwater bivalves, their ongoing introductions, and high ecological and economic impacts demand continued research. Systematic reviews such as this are essential for identifying knowledge gaps and guiding future research to enable a more complete understanding of the ecological implications of invasive bivalves, and the development of effective management strategies.
