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 of the food webs. We compared lakes with different regimes (clear vegetated and turbid), in periods with contrasting hydrological conditions. Samplings were conducted during late summer in 2015 (higher water levels), 2016 and 2017 (lower water levels). In each lake we measured limnological variables an...

Los lagos urbanos son ecosistemas que tienden a una rapida eutrofizacion y que pueden desarrollar floraciones fitoplanctonicas en el periodo estival. En tres lagos urbanos de la Ciudad Autonoma de Buenos Aires (Regatas, Rosedal y Centenario), sometidos a diferentes estrategias de manejo, durante el periodo calido septiembre 2014 - abril 2015 se estudio la estructura y la dinamica del fitoplancton, y se analizo la composicion de especies y de grupos funcionales, y su relacion con parametros ambie...

In order to evaluate patterns of phytoplankton community structure and primary production limitation, we analyzed the phytoplankton communities (chlorophyll a, biovolume, species richness, and primary production) of a set of 20 shallow lakes encompassing a wide range of phosphorus and light levels. The degree of limitation or co-limitation by phosphorus and/or light was estimated using a combined index. We found a direct relationship between irradiance in the water column (I mean) and the light ...

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 basaltic plateaus, located in one of the most arid regions of South America, hold thousands of shallow lakes and ponds and some large lakes, where vegetated lakes are the prime habitat for waterbirds, including endemic threatened species. We studied 31different lakes at the two main Patagonian plateaus (Strobel an...

Abstract We characterized molecularly the first freshwater member ever reported for the family Bathycoccaceae in Lake Musters (Argentinean Patagonia). Members of this family are extremely numerous and play a key ecological role in marine systems as primary producers. We cloned a fragment comprising the SSU rRNA gene + ITS region from environmental DNA using specific mamiellophyte primers. The unique SSU rRNA gene sequence obtained clustered robustly with Bathycoccus prasinos . Analysis of the tw...
