“…This is most probably due to the stress that the spatial and temporal variability of the lagoonal environment of the ponds poses for the biota, allowing only the adapted brackish waters and lagoonal species to dominate (Barnes, 1994). On the other hand, numerical abundance of both phytoplankton and macrofauna was much higher in the ponds than in the adjacent nearshore marine environment.…”

This paper focuses on the structure of the phytoplankton and macrobenthic invertebrates communities in a productive solar saltworks, as well as the major abiotic determinants of the observed biotic patterns. The observed patterns in the structure of the biotic communities attest that the ecosystem of the low salinity ponds of Kalloni Saltworks is similar to a productive coastal lagoon. Major abiotic determinants include the salinity and confinement gradients, as well as inorganic nutrients loads. The episodic enrichment of the water column in the ponds with either new nutrients from the incoming seawater, or regenerated nutrients released from the sediment, was shown to stimulate the growth to bloom levels of phytoplankton species indicative of organic enrichment and coastal eutrophication. Algal biomass and the accumulated detritus and organic matter on and within the sediment are exploited by opportunistic herbivores and deposit feeders tolerant to organic enrichment. Management measures are needed for the mitigation of the productiveness of the low salinity ponds, e.g. lower water residence times, a shallower water column, facilitation of the oxygenation of the sediment, sediment removal in winter and culture and harvesting of the naturally occuring, edible Cerastoderma glaucum bivalves.

“…Likewise, the accumulated detritus and organic matter on and within the sediment is exploited by opportunistic deposit feeders (e.g. Capitella capitata, Malacoceros fuliginosus, Microdeutopus gryllotalpa, Chironomidae) tolerant to organic enrichment (Barnes, 1994).…”

“…For at least two species that decrease in their distribution, the current salinity range cannot be the problem. These species are Nereis diversicolor, although larvae are less tolerant than adults (Wolff 1973;Barnes 1994) and Ficopomatus enigmaticus.…”

The former tidal inlet Lake Veere was turned into a stagnant brackish lake in 1961. Ever since, the system has shown a continuous degradation. The current study shows the monitoring results for the macrozoobenthic communities and the abiotic conditions for the period 1990-2008. This includes the first step to remediation, the restoration of the exchange between the tidal marine Eastern Scheldt and Lake Veere in 2004. A continuous decline in water clearance co-occurring with decreasing macrofauna densities and richness was observed till 2004. Water quality (e.g., secchi depth, nutrient levels, and oxygen conditions) improved significantly after the measure at a higher salinity level with less variation. But the macrofauna densities, biomass, and diversity did not improve yet. First indications of changes in the benthic communities by arrival of new and returning species are however observed and show that restoration at macrofauna level follows the improved abiotic conditions with a delay of several years.

“…Biodiversity, therefore, tends to be low and lagoons are inhabited by organisms that have a broad tolerance to fluctuating conditions. Lagoons also tend to contain a narrow range of niches and mainly favour a suite of organisms adapted to shallow, soft sediment habitats (Barnes 1994;. Nevertheless, like estuaries, lagoons are highly productive and important feeding and migratory sites for waterfowl and shorebirds (Nelson-Smith 1977;Barnes 1980;Gillespie et al 1991).…”

“…Herbarium acronyms are as in Holmgren et al (1990), except for the Sir Wilfred Grenfell College (SWGC) which is not yet listed. Vascular plant nomenclature follows Crow and Helquist (2000), that of invertebrate groups, Barnes (1994), and fishes, Scott and Crossman (1973). Methods for gametangial measurements and illustrations are consistent with those described in Mann (1994b).…”

Charophytes of Insular Newfoundland II: <em>Chara evoluta</em> and <em>Chara canescens</em>

The rare Newfoundland disjuncts Chara evoluta and Chara canescens are compared morphologically, ecologically, and geographically. Although very similar morphologically, they can readily be distinguished by their monoecious/dioecious nature, cortical cell features and coronula size. Ecological differences are more subtle and difficult to quantify. In Newfoundland the two species are restricted to coastal saline lagoons in the southwest region of the Island, with C. evoluta exhibiting an association with Chara aspera. The flora and fauna of these unique habitats are poorly documented even though it is known that they are associated with other rare species including the Piping Plover and the Banded Killifish. Consideration of some degree of protection as special habitats within the provincial ecological reserve strategy is suggested. An updated key to all species of charophytes known to inhabit Newfoundland and Labrador is included, and a brief overview of their ecological distributions is provided.
