Meteorological factors are associated with most of the interannual variability in primary production at both Castle Lake, California (4 l”N, 122%‘) and Lake Tahoe, California-Nevada (39”N, 12O”W). At Castle Lake, extreme values of annual primary production, either much higher or lower than the long-term average, are likely to occur during the phenomenon of El Nifio/Southern Oscillation. Two plausible pathways for the impacts of these large-scale climate events at Castle Lake were identified…

Interannual fluctuations in primary production: Direct physical effects and the trohic cascade at Castle Lake, California
Direct physical effects and cascading trophic interactions operate together to determine interannual variability in the seasonal pattern .of primary productivity at Castle Lake, California. Principal
Climatic forcing and primary productivity in a subalpine lake: Interannual variability as a natural experiment
We analyzed a 42‐yr record of primary productivity in small, subalpine Castle Lake to determine how climatic variability might influence lake primary productivity. A Pacific Decadal Oscillation (PDO)
The potential effects of global warming on the primary productivity of a subalpine lake.
Atmospheric scientists have predicted that large-scale climatic changes will result from increasing levels of tropospheric CO{sub 2}. The authors have investigated the potential effects of climate
Origins and scale dependence of temporal variability in the transparency of Lake Tahoe, California–Nevada
Secchi depth has been measured in Lake Tahoe an average of every 12 d since July 1967. Because of the unusual clarity of the lake, Secchi depth measurement is responsive to small changes in
Effects of climatic fluctuations and vertical mixing on the interannual trophic variability of Lake Garda, Italy
A linked chain of causal factors—namely, winter air temperature, spring lake temperature, extent of the spring lake overturn, and extent of surface nutrient enrichment—had significant effects on the
In the sentinel-site approach to monitoring ecological resources, relatively small numbers of locations are chosen for intensive study, each location being selected to represent a certain, preferably
Trend, seasonality, cycle, and irregular fluctuations in primary productivity at Lake Tahoe, California-Nevada, USA
Primary productivity has been measured routinely at Lake Tahoe since 1967, and a number of mechanisms underlying variability in the productivity record have now been identified. A long-term trend due
Seasonal dynamics and phytoplankton diversity in high mountain lakes (Jöri lakes, Swiss Alps)
The development of the phytoplankton in two years with very distinct weather situations was compared. In 1996, the ice on Jori Lake III melted in mid June, summer stratification persisted during two

SummaryWe investigated the effects of climate variability on the thermal structure of Lake Tahoe, California-Nevada, 1970–2002, and with principal components analysis and step-wise multiple
Long time series from the English Lake District : irradiance-dependent phytoplankton dynamics during the spring maximum
We analyzed rates ofphytoplankton increase and decline during the spring maximum via long-term (25 yr) records of biomass (ChI a) and abundance of the dominant diatom, Asterf-· onella formosa,


Climatic Forcing: Effects of El Ni�o on a Small, Temperate Lake
Temperature profiles measured regularly for 21 years reveal the interannual differences in winter-to-summer heat gain in Castle Lake, California, a small subalpine lake, where the seasonal thermal structure for years in which the lake gains significantly more or less heat than normal is shown.
Climatological estimate of the average monthly energy and water budgets of Lake Tahoe California‐Nevada
An estimate of the average monthly energy and water budgets of Lake Tahoe, California-Nevada is made from commonly available meteorological, hydrological, and limnological data. The water budget
Influence of Salmonine Predation and Weather on Long-Term Water Quality Trends in Lake Michigan
Trends in Lake Michigan water quality over 1975–84 appear to reflect reduced nutrient loadings as indicated by gradual declines in spring total phosphorus (TP) and summer epilimnetic chlorophyll a
A 116-yr Southern Oscillation index record was used in conjunction with environmental data and reports from various authors on disturbances to the anchoveta fishery, marine bird life, etc. off the
Heat Budgets of Lakes
The heat budget of a lake can best be described as its integrated, thermal response to its external physical climate. Unlike oceans where large-scale advective processes play a major role in the heat

Biological Consequences of El Ni�o
Evidence from 1982 and 1983 suggests effects on higher organisms such as fish, seabirds, and marine mammals, but several more years of observation are required to accurately determine the magnitude of the consequences on these higher trophic levels.
Factors regulating phytoplankton production and standing crop in the world's freshwaters
A regression analysis of global data for freshwater phytoplankton production, chlorophyll, and various nutrient parameters revealed that a high proportion of the variance could be explained by annual phosphorus input (loading), once a simple correction for water renewal time was applied.
The Importance of Regenerated Nitrogen to Phytoplankton Productivity to Phytoplankton Productivity in a Subalpine Lake
The importance of this rapid turnover of nitrogen to phytoplankton growth is consistent with the results of previous Castle Lake studies, and with the current conceptual model of primary production in the mixed layer of nitrogen—deficient marine ecosystems.
