Mixotrophy is the occurrence of phagotrophy and phototrophy in the same organism. In
ciliates the intracellular phototroph can be unicellular green algae (zoochlorellae) …

Mutual interactions in the form of symbioses can increase the fitness of organisms and
provide them with the capacity to occupy new ecological niches. The formation of obligate …

Acquisition of phototrophy is widely distributed in the eukaryotic tree of life and can involve
algal endosymbiosis or plastid retention from green or red origins. Species with acquired …

Deep chlorophyll maxima (DCM) are absolute maxima of Chlorophyll-a concentration
among the vertical profile that can be found in deep layers of stratified lakes. In this …

Freshwater lakes are subject to variable degrees of eutrophication. Within lakes, the
planktonic bacterial community (PBC) and sediment bacterial community (SBC) are both …

Planktonic ciliate composition and distribution together with physicochemical variables were
investigated in a shallow hypersaline lagoon, Pulicat, India, during three seasons, ie, pre …

We measured biomass and primary production of picophytoplankton (PicoPhy: 0.2–2 μm)
and of autotrophic size fraction> 2 μm in six deep ultraoligotrophic lakes in the Andean …

High Hg levels in the pristine lacustrine ecosystems of the Nahuel Huapi National Park, a
protected zone situated in the Andes of Northern Patagonia, Argentina, have initiated further …

This study showed first results on the geographical distribution of mixotrophic ciliates of the
genus Stentor in the Chilean North Patagonian Lake District. Thirteen deep North …

The light climate at the deep chlorophyll maxima (DCM) was analysed in a set of lakes of the
North Patagonian Andean region. Apparent and inherent optical properties in relation to the …
