In this first worldwide synthesis of in situ and satellite-derived lake data, we find that lake summer surface water temperatures rose rapidly (global mean= 0.34°C decade ) between 1985 and 2009. Our analyses show that surface water warming rates are dependent on combinations of climate and local characteristics, rather than just lake location, leading to(More)
Global environmental change has influenced lake surface temperatures, a key driver of ecosystem structure and function. Recent studies have suggested significant warming of water temperatures in individual lakes across many different regions around the world. However, the spatial and temporal coherence associated with the magnitude of these trends remains(More)
Changes in the seasonal dynamics of phytoplankton are potentially important, because they can generate a mismatch between the timing of peak productivity and that of consumers, thereby interrupting energy flow between trophic levels. Here, we use a long term data set for the phytoplankton community in the southern basin of Lake Baikal, Siberia to analyse(More)
The effect that climate change in the Lake Baikal region has on the state of the lake plankton is discussed. The increase in water temperature in the photic layer and chlorophyll a content during direct stratification is demonstrated with the use of a database containing the results of plankton observations from 1951 to 2000. The number of small-cell algae(More)
Multivariate autoregressive (MAR) models have been useful in elucidating food web dynamics and stability from freshwater plankton monitoring data, but their applicability to marine datasets has not been as well explored. Characteristics of marine systems, such as the movement of water masses by tides and currents, may present unique challenges to MAR(More)
Large-scale climate change is superimposed on interacting patterns of climate variability that fluctuate on numerous temporal and spatial scales—elements of which, such as seasonal timing, may have important impacts on local and regional ecosystem forcing. Lake Baikal in Siberia is not only the world’s largest and most biologically diverse lake, but it has(More)
