Bacterial community structure in a latitudinal gradient of lakes: the roles of spatial versus environmental factors
SUMMARY 1. We analysed the latitudinal variation of bacterioplankton in 45 freshwater environments (lakes, shallow lakes and ponds) across a transect of more than 2100 km stretching from ArgentineanExpand

Microbial eukaryote communities exhibit robust biogeographical patterns along a gradient of Patagonian and Antarctic lakes.
Microbial eukaryotes play important roles in aquatic ecosystem functioning. Unravelling their distribution patterns and biogeography provides important baseline information to infer the underlyingExpand

Microbial planktonic communities of freshwater environments from Tierra del Fuego: dominant trophic strategies in lakes with contrasting features
We analysed the structure of the microbial plankton communities of different typesof freshwater environments from the southernmost region of South America (Tierradel Fuego). Water bodies were groupedExpand

Grazing rates of protists in wetlands under contrasting light conditions due to floating plants
We examined the effect of light attenuation, due to floating plants, on the community structure of the main phagotrophic protists and their grazing rates in a wetland in the Lower Parana Basin.Expand

Picoplankton abundance and cytometric group diversity along a trophic and latitudinal lake gradient
The picoplankton (PP) is responsible for major ecosystem functions in most aquatic environments. However, not much is known about the factors that regulate its total abundance and communityExpand

Zooplankton succession during extraordinary drought–flood cycles: A case study in a South American floodplain lake
Abstract We examined the zooplankton abundance and composition of Laguna Grande, a floodplain wetland of the Lower Parana Basin (Argentina), during an extraordinary drought–flood cycle that affectedExpand

Which environmental factors trigger the dominance of phytoplankton species across a moisture gradient of shallow lakes?
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 mainExpand

In situ prey selection of mixotrophic and heterotrophic flagellates in Antarctic oligotrophic lakes: an analysis of the digestive vacuole content
We investigated the selective predation of mixotrophic and heterotrophic flagellates(MF and HF) on different heterotrophic prokaryote phylotypes (HPP; Bacteria þArchaea) living in natural assemblagesExpand

Seasonal-dependence in the responses of biological communities to flood pulses in warm temperate floodplain lakes: implications for the “alternative stable states” model
In floodplains located in temperate regions, seasonal variations in temperature affect biological communities and these effects may overlap with those of the flood regime. In this study we exploredExpand
