Drivers of phytoplankton diversity in Patagonian and Antarctic lakes across a latitudinal gradient (2150 km): the importance of spatial and environmental factors
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.Expand

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

Presence, abundance and bacterivory of the mixotrophic algae Pseudopedinella (Dictyochophyceae) in freshwater environments
The genus Pseudopedinella has been described as mixotrophic; however, ecological information about this algal stramenopile (Heterokonta) is unclear. We investigate the environmental conditions thatExpand

Metabolic dependence of phytoplankton species richness
Aim To analyse the dependence of phytoplankton species richness on temperature within the framework of the metabolic theory of ecology (MTE) with explicit consideration of its assumptions andExpand

Microbial planktonic communities in lakes from a Patagonian basaltic plateau: influence of the water level decrease
In this study we analyzed the structure of the microbial planktonic communities in 16 lakes located in one of the Patagonian plateaus. In these environments picoplankton constitute a key component ofExpand

Both lake regime and fish introduction shape autotrophic planktonic communities of lakes from the Patagonian Plateau (Argentina)
Strobel Plateau hosts more than 1,500 shallow lakes displaying different water regimes, which constitute the habitat for many species. Although the region is naturally fishless, many of the lakesExpand

When the tiny help the mighty: facilitation between two introduced species, a solitary ascidian and a macroalga in northern Patagonia, Argentina
Facilitation is recognized as one of the mechanisms by which nonnative species are integrated into new assemblages. The solitary ascidian Styela clava and the macroalga Undaria pinnatifida wereExpand

Influence of fish introduction and water level decrease on lakes of the arid Patagonian plateaus with importance for biodiversity conservation
Abstract Biodiversity loss in shallow lakes is associated to several factors among which water level decrease and fish introduction are indicated as potential stressors. The Patagonian basalticExpand
