Distinct oxygen environments shape picoeukaryote assemblages thriving oxygen minimum zone waters off central Chile
(Oxford University Press, 2020-09)
Oxygen minimum zones (OMZs) support ocean biogeochemical cycles of global importance. The OMZ off central Chile is characterized by seasonally variable oxygen concentrations due to upwelling events. Bacterial and archaeal ...
Los protistas mixotróficos en la estructura trófica planctónica de lagos Norpatagónicos
En ambientes lacustres con una alta relación luz:nutrientes, como son los lagos andinos norpatagónicos, los protistas mixotróficos dominan la producción primaria y conectan la producción microbiana con el zooplancton y los ...

Top-down effects of an exotic serpulid polychaete on natural plankton assemblage of estuarine and brackish systems in the SW Atlantic
(Coastal Education & Research Foundation, 2014-11)
The invasive reef-building polychaete Ficopomatus enigmaticus (Fauvel, 1923) has become well-established in many temperate brackish waters. To analyze preferences for different planktonic food sources, short-term (~1.5 h), ...
High sensitivity of 454 pyrosequencing for detection of rare species in aquatic communities
(Wiley, 2013-06)
1. Concerns regarding the rapid loss of endemic biodiversity, and introduction and spread of non-indigenous species, have focused attention on the need and ability to detect species present in communities at low abundance. ...
Picocyanobacteria aggregation as a response of predation pressure: The direct contact is not necessary
(Wiley Blackwell Publishing, Inc, 2020-08)
Picocyanobacteria (cells <2 µm) can be found either as single-cells (Pcy) or embedded in a mucilaginous sheath as microcolonies or colonies (CPcy). It has been demonstrated that phenotypic plasticity in picocyanobacteria ...
Grazing impact and prey selectivity of picoplanktonic cells by mixotrophic flagellates in oligotrophic lakes
(Springer, 2019-03)
Mixotrophy by planktonic algae can dominate picoplankton predation in oligotrophic environments. We compared the grazing activity and prey preference of different mixotrophic taxa from natural communities of two oligotrophic ...
