“…When softwater lakes in SW Norway reacidified after liming, the elevated CO 2 and NH 4 + availability resulted in luxurious growth of J. bulbosus (Schuurkes et al, 1987;Roelofs, Brandrud & Smolders, 1994;Lucassen et al, 1999), while in Sweden, liming of softwater lakes has led to massive expansions of M. alterniflorum (Roelofs, 1983;Dickson et al, 1995;Brandrud, 2002).

Could rising aquatic carbon dioxide concentrations favour the invasion of elodeids in isoetid‐dominated softwater lakes?

Summary 1. During the past century, isoetid vegetation types in softwater lakes have often been invaded by faster‐growing elodeids. In these C‐limited systems, this may be related to rising aquatic CO2 levels. 2. In a laboratory experiment we tested the growth response of two elodeid species, Myriophyllum alterniflorum and Callitriche hamulata, at four different CO2 levels, ranging from 20 to 230 μmol L−1. In addition, we tested the effect of the nutrient status of the sediment on the growth of C. hamulata at the different CO2 levels. 3. Shoot and root growth increased with rising CO2 availability. Irrespective of sediment type, growth was minimal to negative at the lowest CO2 treatment level, while becoming positive at CO2 levels around 40–50 μmol L−1. Substantial growth was only obtained when the macrophytes were growing on mesotrophic sediments. The plants reached close to maximal growth at CO2 levels of c. 100 μmol L−1. 4. Within this experiment, the growth of C. hamulata at CO2 levels above 90 μmol L−1 may have been limited by N and P availability in both sediment types. The growth rate of M. alterniflorum did not seem to be limited by N and P availability, most likely due to its much higher relative root production. 5. The experimental results show that neither M. alterniflorum nor C. hamulata is able to invade isoetid‐dominated softwater lakes at very low aquatic CO2 concentrations. However, if the sediments contain enough nutrients, a rise in aquatic CO2 could allow the invasion of elodeid species leading to the subsequent disappearance of slow‐growing isoetids.

“…Several hypotheses have been forwarded to explain the massive increase in J. bulbosus biomass in rivers and lakes, the most common being the growth in hydropower development with resulting alterations in hydrology and ice cover (Rørslett, 1987(Rørslett, , 1990Johansen, 1993;Johansen et al, 2000;Hindar et al, 2003), increased water temperature (Rørslett, 1987;Johansen, 1993;Hindar et al, 2003) and acidification, liming and reacidification (when liming is terminated) coupled with an increase in CO 2 and sediment ammonium and phosphorus (Aulio, 1987;Svedäng, 1992;Roelofs, Brandrud & Smolders, 1994;Roelofs et al, 1995;Lucassen et al, 1999). However, in Norway, we find massive J. bulbosus growth in waters both with and without hydropower development, at both low and high altitude, and in both limed and unlimed lakes and rivers, such that a consistent explanation for J. bulbosus nuisance growth in both rivers and lakes is still lacking.…”

Nuisance growth of Juncus bulbosus: the roles of genetics and environmental drivers tested in a large‐scale survey

et al. 2012

View full text Add to dashboard Cite

Summary 1. Invasive species can transform aquatic ecosystems, and the nuisance growth of the freshwater macrophyte Juncus bulbosus has become a problem in many lakes and rivers in northern Europe. It affects biodiversity strongly and conflicts with human uses, not least compromising the generation of hydroelectricity. The causes of the proliferation of these massive stands of J. bulbosus are not finally resolved, however. 2. In this study, a wide range of catchment, lake and sediment parameters (n = 34) were assessed for 139 lakes in Southern Norway, with the aim of explaining the presence or absence of J. bulbosus and to assess potential drivers behind its prolific growth. 3. Juncus bulbosus was more often present in lakes with lower pH and phosphate concentrations, and a higher element ratio of dissolved inorganic nitrogen (DIN) to total phosphorus (DIN : TotP). 4. Despite the many parameters measured across substantial environmental gradients, none explained nuisance growth. Genetic screening (amplified fragment length polymorphism fingerprinting) of plants from a subset of lakes and additional river sites also showed no genetic differences between the various growth forms. A macrophyte trophic index, however, suggested that the most problematic growth occurred in the most oligotrophic lakes. 5. The lack of consistent patterns may reflect either factors not assessed in our survey, or that the current extension of stands represents a gradual cumulative response over time, not characterised effectively in our snapshot survey. Nevertheless, we can now exclude some putative causes of nuisance growth, including in particular genetics and N‐deposition.

“…Juncus bulbosus patches usually occurred where organic matter had accumulated. In The Netherlands, Juncus bulbosus is known to colonise acidified softwater lakes that are enriched in nitrogen (Roelofs et al, 1994;Lucassen et al, 1999). Possibly, the different desmid communities on Juncus bulbosus reflect local nitrogen-enriched growth conditions in the lakes.…”

Substrate specificity of periphytic desmids in shallow softwater lakes in Belgium

et al. 2006

View full text Add to dashboard Cite

At 6 sites in 5 mesotrophic softwater lakes in the wetland Zwart Water (Belgium), periphyton samples were collected on different substrates ranging from macrophytes to mosses and sandy sediment. Significant differences between substrates were observed at 5 out of 6 sites studied. The differences between the substrates, however, could not be related to known effects of these substrates on their chemical environment (e.g., excretion of H + ions, CO 2 or allelopatic substances) nor to their morphology. Therefore, differences between substrates were probably related to differences in local environmental conditions associated with these substrates. Differences in desmid community composition between substrates within a lake were always smaller than differences with samples from other lakes.
