Recent technological advances have led to the discovery that free-living, planktonic protozoa are ubiquitous in nature and appear to be important components of pelagic food webs (e.g., fluorescent straining, flow cytometry). Despite this, limited information exists tying their seasonality to rate processes that drive succession patterns. The abundance, and seasonal growth and grazing loss of an entire...
In this study we examine the influence of environmental variability on the α and β diversity of testate amoeba assemblages from plankton samples. The samples were collected in the littoral and pelagic zones of the rivers and lagoons of the Paraná River floodplain, over one hydrological cycle. Seventy-three species were identified. Alpha diversity was similar in both lagoons and rivers. Although the...
