  text: In lakes, trophic change and climate change shift the relationship between
    nutrients and physical factors, like temperature and photoperiod, and interactions
    between these factors should affect the growth of phytoplankton species differently.
    We therefore determined the relationship between P-limited specific growth rates
    and P-quota (biovolume basis) of Stephanodiscus minutulus and Nitzschia acicularis
    (diatoms) at or near light saturation in axenic, semi-continuous culture at 10,
    15 and 20 °C and at 6, 9 and 12 h d−1 photoperiod. Photoperiod treatments were
    performed at constant daily light exposure to allow comparison. Under these conditions,
    we also performed competition experiments and estimated relative P-uptake rates
    of the species. Temperature strongly affected P-limited growth rates and relative
    P uptake rates, whereas photoperiod only affected maximum growth rates. S. minutulus
    used internal P more efficiently than N. acicularis. N. acicularis was the superior
    competitor for P due to a higher relative uptake rate and its superiority increased
    with increasing temperature and photoperiod. S. minutulus conformed to the Droop
    relationship but N. acicularis did not. A model with a temperature-dependent normalised
    half-saturation coefficient adequately described the factor interactions of both
    species. The temperature dependence of the quota model reflected each species’
    specific adaptation to its ecological niche. The results demonstrate that increases
    in temperature or photoperiod can partially compensate for a decrease in P-quota
    under moderately limiting conditions, like during spring in temperate lakes. Thus
    warming may counteract de-eutrophication to some degree and a relative shift in
    growth factors can influence the phytoplankton species composition.

  text: 'When severely degraded fens are rewetted, they often become shallow lakes
    with an average water depth of less than 1 m. The additional high nutrient availability
    in highly decomposed peat soils of these newly formed ecosystems favours the fast
    establishment of a small number of helophytes while the return of lost target
    species like low sedges and brown mosses could be delayed for decades. We hypothesise
    that the phosphorus (P) uptake of the newly developed vegetation substantially
    influences the P cycle in rewetted fens. Therefore, we investigated how much of
    the P released in upper degraded peat soils is pumped across the redox-interface
    between the soil and surface water (=‘P barrier’) during the growing season (∼150
    days) by six helophytes (Phragmites australis, Typha latifolia, Glyceria maxima,
    Carex acutiformis, Carex riparia, and Phalaris arundinacea) in five rewetted fens.
    We then assessed how this would affect the different plant-available P fractions
    in the rooted degraded peat layers. The highest P uptake during the growing season
    (duration 150 days from May to September) was recorded for T. latifolia and G.
    maxima (3.0 and 2.8 g m−2, respectively). Overall, the P uptake was in the range
    of the P mobilisation rates we measured in highly decomposed peat soils (range:
    0.8–15.6 g P m−2, n = 30), but four to 10-fold higher than diffusive net P fluxes
    at the interface between soil and surface water. Accordingly, helophytes are able
    to compensate for the high P mobilisation in degraded peat soils during the growing
    season, by incorporating this P into biomass. On the other hand a large part of
    the plant-P stock is released after die back through leaching and mineralisation,
    which increases the P load of these newly formed shallow lakes and possibly also
    of adjacent water courses. We estimated that it would still take 20–50 years to
    exhaust the large pool of plant-available P in highly decomposed peat soils if
    aboveground biomass was removed. Without any further management apart from fen
    rewetting it is unlikely that the fens will return to low nutrient levels within
    a human life time.'

  text: Diatoms often dominate temperate lakes and rivers in spring, when increasing
    temperature and daylength coincide with decreasing silicate concentrations. Since
    interactions between these factors may be important, we cultivated Stephanodiscus
    minutulus and Nitzschia acicularis (freshwater diatoms) under silicon limitation
    at different temperatures and photoperiods in continuous and batch culture. The
    Monod parameters of Si-limited growth indicated that S. minutulus should be superior
    under Si limitation. The type of interaction between silicate, temperature and
    photoperiod differed between species and indicated that the advantage of S. minutulus
    increases under low temperatures and photoperiods. Competition experiments in
    semicontinuous culture confirmed these predictions and were described accurately
    with a model of factor interactions. Multiple regression analysis of field data
    from a shallow eutrophic lake showed that dissolved silicate (DSi), temperature,
    photoperiod and total phosphorus (TP) were the most important predictors of spring
    centric diatom biovolume, where lower temperatures and photoperiods favour this
    group and higher biovolumes coincide with DSi depletion and higher TP. Pennate
    diatoms depended more on light, winter population size and grazer abundance. Conditions
    in situ suggested that factor interactions play a role during spring under strong
    Si limitation. We propose that the type of interaction reflects specific niche
    adaptation. Understanding interactions between physical factors and nutrients
    will increase our understanding of phytoplankton diversity and predictive accuracy
    of phytoplankton dynamics including combined effects of climate and trophic change.

  text: We investigated the combined effects of thermal pollution from a nuclear power
    plant (NPP) and regional climate warming on the thermal regime of a lake. For
    this purpose, we used the lake model FLake and analyzed 50 years of temperature
    data from Lake Stechlin, Germany, which served as the cooling water reservoir
    for the Rheinsberg NPP from 1966 until 1990. Both modeling and statistical data
    analysis revealed a strong influence of the NPP cooling water discharge on the
    lake water temperatures and the vertical stability of the water column. A remarkable
    effect of thermal pollution consisted of strong vertical mixing in winter produced
    by the discharge of warm water into the lake when ambient water temperatures were
    below 4 °C. This effect caused a significant increase in the deep hypolimnion
    temperatures and a corresponding decrease of the vertical stability in the summer.
    In turn, climate warming had the opposite effect on the summer stability by increasing
    lake surface temperatures. Both the thermal pollution and climate change increased
    the duration of the summer stratification period. Our results suggest that industrial
    thermal pollution in temperate lakes during winter is stored in the deep water
    column until the next winter, whereas heat added in the summer dissipates relatively
    rapidly into the atmosphere. Accordingly, the winter thermal pollution could have
    a long-lasting effect on the lake ecology by affecting benthic biogeochemical
    processes.

  text: 'We measured specific growth rates of Stephanodiscus minutulus, Nitzschia
    acicularis (diatoms), and Limnothrix redekei (cyanobacterium) under fluctuating
    and constant light in semi-continuous culture at 10°C, 15°C, and 20°C and under
    photoperiods of 6 h d−1 and 12 h d−1. Fluctuating light regimes simulated regular
    vertical mixing in lakes with a ratio of euphotic to mixed depth (zeu : zmix)
    of 1 and 0.5 on a cloudless day. Light fluctuations at zeu : zmix = 1 decreased
    the growth rates of S. minutulus, N. acicularis, and L. redekei by 18%, 33%, and
    29%, respectively, compared to constant light at the same daily light supply.
    Temperature had no effect on this decrease. Halving zeu : zmix (simulating deep
    mixing) had the same effect on growth as halving the photoperiod, demonstrating
    that these factors are cumulative. We introduce a simple empirical factor to adjust
    growth rates measured under constant light to account for fluctuating light. This
    factor is independent of temperature and photoperiod, applies over a range of
    zeu : zmix, and accurately describes present and published growth rates of several
    species. We show how to account for temporal variability of the light supply at
    different temperatures and photoperiods when predicting growth rates of phytoplankton.'

  text: Global climate change alters the relationship between temperature and light
    in aquatic ecosystems, which is expected to affect the success of different phytoplankton
    species. To examine this, the interactions between temperature, photoperiod and
    light exposure (LE) (integral daily light supply) on specific growth rates were
    analysed for Limnothrix redekei, Planktothrix agardhii (cyanobacteria), Nitzschia
    acicularis and Stephanodiscus minutulus (diatoms). A model of factor interactions
    was developed based on new (P. agardhii and St. minutulus) and previously published
    laboratory studies. It describes the measured data with high precision. Temperature
    and photoperiod affect the parameters of the light-growth response curve differently,
    but these effects are the same for all species. The link between functions for
    temperature and photoperiod is more species-specific. Using meteorological data,
    the model developed here was used to study the interplay of these factors during
    a spring bloom in Lake Müggelsee (Berlin). It was found that while all three factors
    influenced phytoplankton growth, temperature and photoperiod were more important
    than LE. Both the intensities of the factors and the interactions between them
    influenced each species to a different degree. The results may help improve our
    understanding and ability to predict shifts in phytoplankton communities caused
    by weather patterns and climate change.
