ABSTRACT Paleolimnological reconstructions of past changes in carbon stable isotopic composition chironomid head capsules (δ 13 C HC ) were used to quantify the impacts atmospheric sulphur and nitrogen depositions on processing at base lake food webs. We hypothesised that deposition flows through webs are influenced by nutrient limitation, as increasing inputs expected drive higher primary producer biomass nitrogen‐limited lakes, thus its availability for benthic consumers. The δ values...
Abstract Most studies aiming to explore the response of algae and zooplankton trophic interactions climate variability have only been focused on unidirectional very short‐term trends in temperature changes. As a result, non‐stationary aspect change (warming cooling periods, frequencies) remains completely unstudied. We studied elemental stable isotope composition sedimentary organic matter, photosynthetic pigments, carbon Cladocera resting eggs sediment record covering last c . 2,600 years....
