The morpho-functional classifications of phytoplankton have been recently proposed as useful tools in the aquatic biomonitoring. In this study, we compared three different classifications in a range of different environmental conditions, a set of six shallow lakes with different stable states. The studied lakes are located in the Pampa Plain from Argentina,(More)
We investigated nine Pampean shallow lakes (Argentina) across a moisture gradient (mean annual precipitation 1,000–500 mm), under the framework of a network project of lake monitoring whose main objective was to analyse the responses of ecosystems to different stressors associated with human activities. We postulate that species bloom in different shallow(More)
We aimed to identify the driver/s of phytoplankton diversity (gamma, beta, alpha) and community composition in a Pampean floodplain wetland (Otamendi), using species and functional groups. We performed a seasonal regional survey (2004–2006, phytoplankton regime) across the different aquatic systems in the wetland. Gamma diversity was 254 species. Beta(More)
We investigated the phytoplankton structure in 60 lakes across a latitudinal gradient (2150 km), from Austral Patagonia to Antarctica, including environments ranging from oligotrophic to eutrophic. We analysed the latitudinal variation of species richness (local and regional) and evenness, as well as the similarity decay in phytoplankton composition in(More)
We analysed the changes in phytoplankton and in the main limnological features in a shallow lake during its transition from a clear-vegetated regime to a turbid one from 2005 to 2013. As samplings were discontinuous, data were analysed considering three different sampling periods. At the beginning of the first period, the lake was in a clear-vegetated(More)
We performed a short-term cross-transplant experiment (72 h) using dialysis bags in two shallow lakes with contrasting regimes (clear-vegetated and phytoplankton-turbid). We assessed the changes in the structure of the microbial planktonic communities in response to the variations in the limnological conditions. Important changes were observed in >2(More)
The limnological features of Lake Boeckella, the main water body of Esperanza/Hope Bay (Antarctic Peninsula), were evaluated over a 16-year period, under a climate change context evidenced by the increasing air temperature trend reported for this region for the last 50 years. We analyzed the physicochemical and phytoplankton data of the lake obtained from(More)
This special issue of Hydrobiologia is devoted to the shallow lakes of the Central Plains of Argentina. The contributors were invited to submit papers dealing with different ecological topics including physical features, climatic and geological characteristics of the region, as well as studies focusing on aquatic communities (fish, zooplankton,(More)
