Lake Ladoga (17 891 km 2 ) is the largest lake in Europe, with a 258 000 km 2 drainage area that extends to much of north-western European Russia and eastern Finland. Its ecosystem has been systematically investigated since 1976, and sporadically since the 1950s. Monitoring programmes have included studies on its hydrology, water chemistry and biology (phytoplankton, bacterioplankton, zooplankton, benthos, macrophytes and fish). The sampling frequency per vegetation season (spring, summer and… 
Highlights of large lake research and management in Europe
TLDR
Although large lakes are among the best-studied ecosystems in the world, the application to them of environmental regulations such as the European Water Framework Directive is a challenging task and requires that several natural and management aspects specific to these water bodies are adequately considered.
Current state of bacterial community of Lake Ladoga
Abstract The data are presented on a quantitative assessment of the bacterioplankton community of Lake Ladoga and total bacterial numbers dynamic in the period from 2009 to 2019. The trophic state of
Eutrophication and restoration in temperate lakes
Eutrophication affects many lakes and reservoirs worldwide. It is caused by excessive amounts of nutrients entering waterbodies from their catchments, mainly due to human activity. The main sources
Deglaciation history of Lake Ladoga (northwestern Russia) based on varved sediments
Lake Ladoga in northwestern Russia is Europe's largest lake. The postglacial history of the Ladoga basin is for the first time documented continuously with high temporal resolution in the upper 13.3
A new method to generate a high-resolution global distribution map of lake chlorophyll
A new method was developed, evaluated, and applied to generate a global dataset of growing-season chlorophyll-a (chl) concentrations in 2011 for freshwater lakes. Chl observations from freshwater

The present state of Lake Ladoga, Russia — a review
TLDR
Until the carly 1960s, Lake Ladoga was oligotrophic and characterized by good water quality, but within the past 20-30 years, as a result of human impact, the ecological state seems to have deteriorated, with elevated nutrient concentrations and decreased transparency.
Integrated monitoring of Lake Ladoga, Russia
Lake Ladoga (17,891 km') is the largest lake in Europe; its mean depth is 47 m, maximum depth 230 m, and its 258,000-km' drainage area extends to much of north-western European Russia and eastern
The trophic state of Lake Ladoga as indicated by late summer phytoplankton
As a part of the joint Russian-Finnish evaluation of human impact on Lake Ladoga, we studied the phytoplankton of the lake in order to find biological indicators for eutrophication. A second aim of
Seasonal succession of zooplankton of Lake Ladoga (NW Russia)
Lake Ladoga, the 1argest 1ake in Europe, was oligotrophic until the mid-1960s and became mesotrophic in the 1970s due to intensive eutrophication (RUMYANTSEV et al. 1999). Some long-term trends in
Ecological problems of Lake Ladoga: causes and solutions
Lake Ladoga (the largest lake in Europe) was characterized by good water quality some decades ago. Now as a result of human impact, the saprobity and toxicity of water have changed, phytoplankton

Long‐term changes in the phytoplankton of large lakes in response to changes in nutrient loading
TLDR
A model is suggested based on experiences from more than 50 Swedish lakes investigated during a series of years to get a tool for water management where disturbing and highly disturbing total phytoplankton volumes can be anticipated from a certain phosphorus concentration.
Trophic gradients and associated changes in the plankton community in two bays of Lake Ladoga
Simultaneous analyses of water quality parameters, and the composition of phytoplankton, crustacean and rotifer assemblages were done at two sampling areas in Lake Ladoga: the Sortavala Archipelago
