One of the greatest threats to water quality is accelerated eutrophication, resulting from
human activity, like the high intensity of tourism, surface runoffs from fertilized fields, and …

The ratio of primary production to ecosystem respiration rates (P: R ratio) is an ostensibly
simple calculation that is used to characterize lake function, including trophic status, the …

В книге обобщены многолетние (1976-2006 гг.) данные по первичной продукции
планктона в каскаде волжских водохранилищ. Обсуждается экологическая роль …

We estimated the contributions of sedimentation and cell lysis to the loss of two large
phytoplankton species (Fragilaria crotonensis and Staurastrum dorsidentiferum) in Lake …

We measured stable nitrogen (N) and carbon (C) isotope ratios, lignin-derived phenols, and
fossil pigments in sediments of known ages to elucidate the historical changes in the …

We analyzed the vertical distributions of 19 polycyclic aromatic hydrocarbons (PAHs), total
organic carbon (TOC), total nitrogen (TN) and stable carbon isotope ratio (δ13C) in a 27cm …

The effect of aquatic birds on nutrient cycling and energy flow was investigated in two soda
pans, one turbid and the other colored, with different physical and chemical characteristics …

Vertical distributions of both concentrations and stable isotopic compositions of nitrate,
including the 17O‐excesses (Δ17O), were determined four times during 1 yr within the …

Global climate change and anthropogenic oligotrophication are expected to reshape the
dynamics of primary production (PP) in aquatic ecosystems; however, few studies have …

The nutrient ion concentrations in the interstitial waters of biofilms (BFs) formed on reed and
stone surfaces were investigated in the northern and southern basins of Lake Biwa over …
