“…The main abiotic factors, which influence phytoplankton abundance, seem to be the ice and snow thickness regulating the light penetration. While the ice is not overlaid by snow, the clear ice can transmit even 75-95% of the incoming photosynthetically-active radiation, while the snow cover reduces it to 10% (Wright 1964;Bolsenga & Vanderploeg 1992).…”

“…Low water and air temperature, very low light intensities and short day period combine to reduce phytoplankton growth (Eloranta 1981;Phillips & Fawley 2002b;Barone & NaselliFlores 2003). Moreover, ice-cover and snow layer on the top of the ice may completely (almost 100%) reduce light penetration in the lake (Bolsenga & Vanderploeg 1992). Additionally, ice-cover effectively seals off the water column from the stirring action of wind-induced circulation and accompanying exchange of gases with the atmosphere (Wright 1964;Spaulding et al 1993).…”

Phytoplankton samples were collected from three mesotrophic lakes: Piaseczno, Rogóźno and Krasne during winter seasons (from January to March). The samples were analyzed for species analysis and abundance of planktonic algae in relation to different depths of water column (0-7 m). Selected water physical-chemical parameters were also measured. Abundance of phytoplankton depended strongly on the thickness of snow and ice cover or mixing conditions. The maximal phytoplankton total number reached about 5 × 10 6 ind. L −1 beneath the clear ice in the Krasne Lake, minimal numbers were recorded under the thick snow and ice layers in the Piaseczno Lake (2 × 10 3 ind. L −1 ). The winter phytoplankton communities were dominated by flagellates principally cryptomonads (Cryptomonas spp. Rhodomonas minuta), euglenophytes (Trachelomonas volvocina, T. volvocinopsis), dinoflagellates (Peridinium bipes, Gymnodinium helveticum) and chrysophytes (Mallomonas elongata, M. akrokomos, Dinobryon sociale) or non-motile small species of blue-green algae (e.g. Rhabdoderma lineare, Limnothrix redekei), diatoms (Stephanodiscus spp., Asterionella formosa), and green algae (e.g. Scenedesmus spp., Monoraphidium spp.). Phytoplankton abundance and structure showed differentiation during the winter season and along the water column as well.

“…Bolsenga and Vanderploeg (1992) found that if the ice was not snow covered, the amount of photosynthetically active radiation reaching the top of the water column beneath clear ice in Grand Traverse Bay was -45% of that at the air-ice interface. This 45% is still sufficient for algal production.…”

Records of freezeup and breakup dates for Grand Traverse Bay, Michigan, and Lake Mendota, Wisconsin, are among the longest ice records available near the Great Lakes, beginning in 185 1 and 1855, respectively. The timing of freezeup and breakup results from an integration of meteorological conditions (primarily air temperature) that occur before these events. Changes in the average timing of these ice-events are translated into changes in air temperature by the use of empirical and process-driven models. The timing of freezeup and breakup at the two locations represents an integration of air temperatures over slightly different seasons (months). Records from both locations indicate that the early winter period before about 1890 was -15°C cooler than the early winter period after that time; the mean temperature has, however, remained relatively constant since about 1890. Changes in breakup dates demonstrate a similar 1.0-l .5"C increase in late winter and early spring air temperatures about 1890. More recent average breakup dates at both locations have been earlier than during 1890-l 940, indicating an additional warming of 1.2"C in March since about 1940 and a warming of 1 . 1°C in January-March since about 1980. Ice records at these sites will continue to provide an early indication of the anticipated climatic warming, not only because of the large response of ice cover to small changes in air temperature but also because these records integrate climatic conditions during the seasons (winter-spring) when most warming is forecast to occur. Future reductions in ice cover may strongly affect the winter ecology of the Great Lakes by reducing the stable environment required by various levels of the food chain.

“…Ice formation, for instance, has a substantial influence on the underwater light, temperature, and turbulence regime [4,28]. Thus, changes in the duration of ice cover periods may induce significant changes in the inocula of phytoplankton, which in turn may affect the seasonal succession of plankton.…”

Impacts of climate warming on freshwater ecosystems have been documented recently for a variety of sites around the globe. Here we provide a review of studies that report long-term (multidecadal) effects of warming trends on thermal properties and plankton dynamics in northern hemispheric lakes. We show that higher lake temperatures, shorter periods with ice cover, and shorter stagnation periods were common trends for lakes across the hemisphere in response to the warmer conditions. Only for shallow dimictic lakes was it observed that deepwater temperatures decreased. Moreover, it became evident that phytoplankton dynamics and primary productivity altered in conjunction with changes in lake physics. Algal spring blooms developed early and were more pronounced in several European lakes after mild winters with short ice cover periods, and primary productivity increased in North American lakes. Effects of elevated temperatures on zooplankton communities were seen in an early development of various species and groups, as is documented for cladocerans, copepods, and rotifers in European lakes. Furthermore, thermophile species reached higher abundance in warmer years.Obviously, the nature of responses is species specific, and depends on the detailed seasonal patterning of warming. Complex responses such as effects propagating across trophic levels are likely, indicating that observed climateecosystem relationships are not generally applicable. Nonetheless, the picture emerges that climate-driven changes in freshwater ecosystems may be synchronised to a certain extent among lakes even over great distances if climatic influences are not masked by anthropogenic impacts or differences in lake morphology. Macro-scale climatic fluctuations -such as the North Atlantic Oscillation or the El Niño-Southern Oscillation -were identified as the most important candidates responsible for such coherence, with the former predominating in Europe and the latter in North America. We emphasise, however, that the driving mechanisms and the future behaviour of these oscillations are Gerten and Adrian: Climate Warming on Freshwater Ecosystems TheScientificWorldJOURNAL (2002) 2, 586-606 587 rather uncertain, which complicates extrapolation of observed effects into the future. Thus, it is necessary to quantify the most important climate-ecosystem relationships in models of appropriate complexity. Such models will help elucidate the multiple pathways climate affects freshwater ecosystems, and will indicate possible adverse effects of a warmer future climate.KEY WORDS: climate change, freshwater ecosystems, North Atlantic Oscillation, El Niño-Southern Oscillation, lake ice, long-term, phytoplankton, zooplankton, large-scale synchronization DOMAINS: freshwater systems, ecosystems and communities, atmospheric systems, ecosystems management INTRODUCTIONWeather and climate regulate physical, chemical, and biological processes in freshwater ecosystems at all time scales [1].
