“…In the case of Fuente de Piedra lake this shadow effect, related to eutrophication phenomena, would be mostly due to the growth of the filamentous algae U. flexuosa. A similar phenomenon has been reported in a shallow alkaline mill-pool which had about 60 % of its surface covered by filamentous algae in forms of floating or benthic mats (Irfanullah & Moss, 2004).…”

Conde-Álvarez, R.M., Bañares-España, E., Nieto-Caldera, J.M., FloresMoya, A. & Figueroa, F.L. 2012. Submerged macrophyte biomass distribution in the shallow saline lake Fuente de Piedra (Spain) as function of environmental variables. Anales Jard. Bot. Madrid 69(1): 119-127.Aquatic macrophyte biomass, diaspore bank distribution and their relationship to spatial variability of depth, nutrients (nitrite, nitrate, ammonium and soluble reactive phosphorus) as well as sediment granulometry in an athalassohaline lake have been studied during one wet hydrological year. The results indicate that species growing in the lake show different spatial distribution patterns throughout the lake. Indirect gradient analysis (canonical analysis) results showed a first axis defined as a function of Ulva flexuosa Wulfen biomass which is, in turn, positively correlated with interstitial ammonium and Soluble Reactive Phosphorus (SRP). The second axis was mainly established due to Lamprothamnium papulosum (Wallr.) J. Groves biomass which correlated positively to depth and negatively to interstitial ammonium and SRP. These results revealed a NE-SW eutrophic gradient allowing the U. flexuosa biomass proliferation. This phenomenon could increase the shadow effect over the rest of the macrophytes inhabiting this shallow lake. Moreover, the eutrophic harmful effect on the macrophyte physiology and over the diaspore bank could have important consequences in the survival of such important populations. The results reported in this study show the need for studies as the base to select sampling points for monitoring this wetland.Keywords: submerged macrophytes, eutrophication, lakes, maps, Fuente de Piedra, Spain.

“…The question whether herbivores can prevent the colonisation of macrophytes in restored shallow water bodies is debated. Experiments where macrophytes were transplanted in restored lakes showed that herbivores (large fish and waterfowl) strongly reduced macrophyte biomass (Lauridsen et al, 1993;Sondergaard et al, 1996;Lauridsen et al, 2003b;Irfanullah & Moss, 2004;Van de Haterd & Ter Heerdt, 2007;Moore et al, 2010). However, Perrow et al (1997) and Strand & Weisner (2001) found no significant reduction due to herbivory by fish and birds in restored lakes of the biomass of macrophytes that had developed spontaneously, whereas Hilt (2006) found a more than 90% reduction of P. pectinatus vegetation through grazing.…”

“…However, with increasing nutrient loading, phytoplankton biomass may increase, creating water turbidity which may result in light limitation and disappearance of submerged macrophytes (Scheffer et al, 1993). However, before the water becomes turbid, there can be direct shading of macrophyte leaves by the accumulation of epiphyton or filamentous algae, which causes macrophyte decline or inhibits their return (Phillips et al, 1978;Weisner et al, 1997;Jones & Sayer, 2003;Roberts et al, 2003;Irfanullah & Moss, 2004;Hilt et al, 2010). Besides the indirect effect of nutrients on macrophyte growth (via light limitation), certain nutrients can be toxic for macrophytes, including ammonium which can be toxic at high concentrations for many macrophyte species (Smolders & Roelofs, 1996), whereas nitrate has been shown to reduce the growth of Chara species (Lambert & Davy, 2011).…”

Restoring macrophyte diversity in shallow temperate lakes: biotic versus abiotic constraints

et al. 2012

Although many lake restoration projects have led to decreased nutrient loads and increased water transparency, the establishment or expansion of macrophytes does not immediately follow the improved abiotic conditions and it is often unclear whether vegetation with high macrophyte diversity will return. We provide an overview of the potential bottlenecks for restoration of submerged macrophyte vegetation with a high biodiversity and focus on the biotic factors, including the availability of propagules, herbivory, plant competition and the role of remnant populations. We found that the potential for restoration in many lakes is large when clear water conditions are met, even though the macrophyte community composition of the early 1900s, the start of humaninduced large-scale eutrophication in Northwestern Europe, could not be restored. However, emerging charophytes and species rich vegetation are often lost due to competition with eutrophic species. Disturbances such as herbivory can limit dominance by eutrophic species and improve macrophyte diversity. We conclude that it is imperative to study the role of propagule availability more closely as well as the biotic interactions including herbivory and plant competition. After abiotic conditions are met, these will further determine macrophyte diversity and define what exactly can be restored and what not.

“…We conclude that the extensive turfs (up to 4 cm thick) of Corallina officinalis at sites southeast of the Boags Rocks outfall (Brown et al 1990) are very likely to inhibit re-establishment of H. banksii, even if water quality was conducive to early development and growth. Alternate stable states are often resistant to restoration efforts because of positive feedbacks that maintain the state (Irfanullah & Moss 2004, Troell et al 2005, Young et al 2005). This study shows that restoring the H. banksii habitat and associated species at southeastern sites (e.g.…”

Fucoid algae often dominate intertidal rocky shores, providing habitat and modifying ecosystem resources for other species, but are susceptible to discharge of sewage effluent. In this study we assessed the potential for competition from coralline turfs to inhibit restoration of the intertidal fucoid macroalga Hormosira banksii at sites associated with an ocean outfall a scenario of improving following water quality in the nearshore coastal environment. The percentage cover and number of individuals of H. banksii were negatively correlated with both the percentage cover and turf height of Corallina officinalis. In contrast, H. banksii was positively associated with rocky substrata and recruited well to rock-surface substrata. Importantly, there appears to be a threshold abundance where the percentage cover of H. banksii rarely reaches above 20% cover amongst coralline turfs with > 40% cover. These data support a model of alternative community states: H. banksii dominated canopy on rocky substrata versus C. officinalis turf. In field and laboratory experiments, extensive coralline turfs (up to 4 cm thick) were shown to inhibit recruitment of H. banksii. This study shows competitive exclusion by coralline turfs may limit the successful restoration of habitat provided by H. banksii to shores that have been affected by sustained discharge of secondarily treated sewage effluent. We suggest potential strategies for management authorities to consider when seeking ways of restoring fucoid communities affected by anthropogenic disturbances such as wastewater disposal.KEY WORDS: Hormosira banksii · Restoration · Sewage effluent · Recruitment · Competition · Ecosystem engineer · Alternative stable states Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 419: [47][48][49][50][51][52][53][54][55][56] 2010 effluent discharge (Manning 1979, Brown et al. 1990, Doblin & Clayton 1995, Kevekordes 2000, 2001.Melbourne, the coastal capital city of Victoria, Australia, has a population of 3.81 million (ABS 2007) and a daily sewage effluent discharge of 855 × 10 6 l (MW 2009).

Hormosira banksii has disappeared completely from Boags Rocks and is greatly reduced in abundance at sites to the southeast of the outfall since the commencement of effluent discharge in 1975 (Manning 1979, Brown et al. 1990, Bellgrove et al. 1997.
