    ABSTRACT: Regular ecological investigations usually on a fortnightly basis have been carried out at the Saidenbach Reservoir (SE Germany) and its tributaries since 1975. The data show a sudden decrease in the phosphorus import of over 60% in 1990, resulting in the abrupt change of the trophic state from eutrophic to weakly mesotrophic. Contrary to expectations, the average annual phytoplankton abundance did not decrease but almost doubled on average over the years after 1990. This was primarily due to mostly warmer winters after 1990 causing longer spring overturns, which minimized sedimentation losses, enabled better utilization of the phosphorus reserves, and resulted in higher yields of the diatom-dominated phytoplankton spring mass development. In the summers after 1990, the mass growth of the diatom Fragilaria crotonensis, which in the past used to dominate in this season and effectively transported phosphorus to the sediment by settling, was considerably reduced because of lower P supply and stronger stratification. However, the decrease in the biomass of Fragilaria was overcompensated by the increased abundance of cyanobacteria. They benefitted not only from declining phosphorus competition by Fragilaria but also from higher thermal stability and temperature in the epilimnion. Hence, even higher summer biomasses were observed despite considerably lowered phosphorus import. The analysis of the long-term dataset clearly illustrates the deciding impact of hydrophysical factors on the phytoplankton growth, also under nutrient deficient conditions. The altered mixing and stratification pattern caused by climate change did not only prevent the re-oligotrophication of the reservoir but even enhanced the phytoplankton production. It seems that global warming modifies the interplay between physical and nutrient limitation mechanisms and the limits and models used in the past to classify trophic-state levels have to be verified. The study shows the enormous significance and indispensability of uninterrupted ecological long-term datasets, including reliable data of the ecosystem's organismic structure, for research about the consequences of climate change.

    ABSTRACT: Mass aggregation of waterfowls for breeding, results in allochthonous nutrient inputs into aquatic systems. This study evaluated accumulation of bird droppings as allochthonus nutrient input and its fluctuations in Anavilundawa International Ramsar Sanctuary in Sri Lanka where Asian openbill (Anastomus oscitans) mass breeding occurs annually. Reservoir was divided into four strata: Inlet, breeding ground, reservoir centre and outlet. The highest nutrients levels (NO3-�, PO43-�, NH4+, alkalinity) and the lowest dissolved oxygen and pH levels were recorded in breeding grounds for both surface and bottom water. The highest turbidity was recorded in inlet surface and centre bottom water. Canonical Variate Analysis of water quality parameters indicated the significantly distinct influence of ornithological eutrophication on surface water of four strata whilst, showing similarities in water quality of bottom layers in inlet and outlet. In the breeding ground, surface water was covered with thick mats of aquatic flora consisting of Water hyacinth, Salvinia, duckweed and Polygonum. Therefore, it is concluded that in addition to dilution, amelioration of water quality could also be happening due to absorption by plants. Due to interactions between invasive plants and waterfowls, restoration with native aquatic flora is needed to be considered to regain reservoir resilience and self-sustenance.

    ABSTRACT: In recent years, there has been an increasing interest in the ecology of algal species Gonyostomum semen (Ehr.) Diesing, as it is often referred as an invasive species and a climate change indicator. Like many other flagellates, the species has the ability to active swimming, therefore it is often found unevenly distributed in the water column. Although there are several studies focused on the species vertical distribution (VD) and its diurnal changes, there is no general agreement about the causes and mechanisms of the phenomenon. In this paper, we analyzed G. semen VD in three stratified humic lakes in the new area of its spread in Central Europe, aiming to determine the common pattern of this phenomenon as well as to search any relationship with chemical and biotic factors. The results of this investigation showed that VD of the alga during the day varied among three lakes and that Gonyostomum migrated upward in the morning and downward in the afternoon, but it could stay in deep, anoxic and dark layers through most of the diurnal cycle. The analysis of chemical factors revealed that phosphate retrieval from deeper layers is probably not a key driver of the alga uneven VD and its migrations. Diurnal observations showed that three dominating zooplankton species (Asplanchna priodonta, Ceriodaphnia quadrangula, and Eudiaptomus graciloides) changed their vertical position in parallel to Gonyostomum. We have suggested in conclusions that the pattern of G. semen VD in temperate stratified lakes is not universal, but rather depends on particular lake conditions, including phosphate content and light climate. Since the zooplankton VD could play a regulating role in the alga behavior, further research in this field would be of great help in understanding this invasive alga ecology. =======© 2013 WILEYVCH Verlag GmbH & Co.

    ABSTRACT: We investigated the influence of light on phototactic behavior and reproduction in two species of rotifer from the Brachionus plicatilis species complex (B. plicatilis sensu stricto (s. s.) and Brachionus manjavacas). This was done to understand how light effects these species so that we might use this knowledge to establish a more efficient aquaculture protocol. We used four different light wavelengths (white, with peaks at 460 and 570 nm; blue at 470 nm; green at 525 nm; and red at 660 nm) and four intensities (i.e., 0.5–30.0 W/m2). Using micro-spectrophotometry we determined that eyespots of these two Brachionus species absorbed blue and green light 5.5 times more than red light. B. plicatilis s. s. showed positive phototaxis under white, blue, and green light at lower light intensities, but no phototaxis under red light at all intensities (0.5, 6.2, 15.0, and 30.0 W/m2). Similar patterns of phototaxis were observed in B. manjavacas and did not differ among mictic, amictic females, and male rotifers. Population growth rate of B. plicatilis s. s. under dark condition was 1.1–1.2 times higher than that under white light condition. No significant differences were observed in population growth rate at 3.8 and 6.2 W/m2 at all light wavelengths. On the other hand, population growth rates at 0.5 and 1.6 W/m2 were the lowest under blue light. According to these results, both wavelength and intensity of light affect the population growth of rotifers, which in turn may be influenced by the rotifers' wavelength-dependent phototaxis.
