The dilution method is typically applied to estimate the growth and mortality rates of phytoplankton, but it is also used to study bacterioplankton. The method comprises creating a gradient of dilutions to reduce the encounter rates between bacterivo

The biomass, production, composition of autotrophic phytoplankton andhetero-trophic bacteria were studied along with environmental and biologicalparameters. Samples were taken from Vistula river water (at Kiezmark) andfrom the river plume to the oute

The dependence between temperature and clearance rate of the ciliate Balanion comatum Wulff 1919 was assessed in the coastal zone of the southern Baltic Sea. Five in situ experiments were carried out with the use of wheat starch as a surrogate of foo

Nanoflagellates are important bacterivores, but their role isoften underestimated because forms capable of phagotrophy andcontaining chlorophyll (mixotrophs) are excluded from analyses.Research conducted in the coastal zone of the Gdańsk Basin (Balt

The ciliate Mesodinium rubrum Lohmann 1908 (=Myrionecta rubra Jankowski 1976) is an important phototrophic organism in the Gdańsk Basin. In June 2002 the vertical distribution and size structure of the M. rubrum population were studied. Its presence

Life-detection experiments carried out in extraterrestrial locations provided inconclusive results whether processes observed were biological or chemical. In this study, the typical effect of temperature on metabolic rates is described and a life-det

The aim of this study was to evaluate the present state of a small (area of 0.2 ha), shallow (mean depth of 2 m) and approximately 30-year-old post-peat reservoir located in Bruskowskie Bagno, a Baltic raised mire in northern Poland. The study was co

Pelagic and benthic primary production and respiration were measured at an offshore station in the shallow, 1.2 m deep, polymictic Lake Gardno (Poland) to examine the role of the pelagic zone and the sediments in the overall carbon budget of this lak

In aquatic environments, ciliates integrate the energy flowing through bacteria, smaller protozoa, and the prevailing fraction of algae and are further grazed upon by metazooplankton. Ciliates are incorporated into budgets and models describing ecosy
