Phytoplankton plays an important role in the structure and functioning of an aquatic ecosystem, thus affecting other groups of organisms [1]. The growth of phytoplankton depends mainly on the availability of nitrogen and phosphorus [2-4]. Excessive eutrophication caused by high nutrient concentrations (especially phosphorus and nitrogen) along with strong cyanobacterial blooms results in decreasing aquatic ecosystem biodiversity [5].

“…Despite the cyanobacteria presence in phytoplankton communities, the high average value of biodiversity at the level of 3.7 in the winter and spring confirmed a significant share of occasional species, especially diatoms and green algae. On the other hand, the presence of numerous euglenoids and cryptophytes in Lake Łeknenskie demonstrated the high content of organic matter in suspension (Celewicz-Gołdyn et al 2010).…”

Qualitative analyses of nitrogen and phosphorus loads reaching the lake ecosystem provide a basis for pollution control, which is of paramount importance in shallow lakes due to the rapid turn-over of matter and energy. The studies of both external and internal loading were conducted in Lake Łeknenskie, a very shallow, through-flow lake situated in Western Poland. Strong eutrophication is manifested in rich rush vegetation and a lack of submerged macrophytes as well as nitrogen and phosphorus concentrations (max 13.04 mg N dm−3 and 0.32 mg P dm−3, respectively). Constant domination of cyanobacteria in the phytoplankton community was noted in almost all seasons with a 98% share in summer, resulting in 20 cm water transparency and 223 μg dm−3 of chlorophyll-a. The zooplankton community was dominated by rotifers. The main source of nutrients was the River Nielba. Spatial external nutrient loading was 1.93 g P m−2 yr−1 and 77.55 g N m−2 yr−1. An even higher load of phosphorus was released from the bottom sediments, 2.18 g P m−2 yr−1. A comprehensive action plan is required, aiming at the reduction of both external and internal nutrient loading. A series of solutions regarding local environmental conditions should be applied in the lake catchment, including biogeochemical barriers, denitrification walls, artificial retention basins or wetlands, but most of all – improvement in the functioning of the wastewater treatment plant. Restoration is possible, however, protection measures reducing external loading should be undertaken prior to phosphorus inactivation in the water column and in the bottom sediments, supported by biological methods e.g. biomanipulation.

Humic Substances Delay Aging of the Photosynthetic Apparatus of Chara hispida

In freshwaters, dissolved humic substances (HSs) distinguish apparently HS-avoiding Charophytes from apparently HS-tolerant ones, but the underlying mechanisms so far remain obscure. In this contribution, we tested direct and indirect effects of HSs on Chara hispida (L.) Hartm. Using Rhodamine B, we showed that C. hispida is able to adsorb or even uptake and, subsequently, desorb and depurate organic compounds in the molecular mass range of the applied fulvic acids. To classify direct and indirect HS-mediated effects due to reduced light quantities, or to effects more strongly elicited by red relative to blue light, plants were exposed to HSs directly as well as through a neutral foil, or shaded by means of an external HS-containing reservoir (low-light variant). We showed that the apparently HS-tolerant C. hispida exhibited reduced lipid peroxidation and non photochemical quenching of chlorphyll fluorescence when exposed to HSs. Plants directly exposed to HSs were significantly different from control as well as to foil-shaded plants in terms of chl a+b, VAZ/chl, and β-Car/chl; yet, in low-light plants these variables did not differ from control and HS-exposed plants, suggesting that the shift in favor of red lights in the low-light variant led to a reduction in its cells' internal antioxidant content. However, the Fv/Fm ratio in HS-exposed plants decreased more slowly than in all other exposure variants, indicating that the photosynthetic apparatus aged more slowly, by a mechanism yet to be discovered. Our study indicates that both direct and indirect effects contribute to the HS tolerance of C. hispida.

Relationship between plankton assemblages and habitat characteristics of stands of Typha angustifolia and Chara hispida in Lake Wielkowiejskie

Abstract: The results of investigations performed in Lake Wielkowiejskie showed the influence of macrophyte architecture, understood as plant density, on the structure of plankton communities as well as the habitat preferences of particular species in both seasonal and spatial aspects.
