Grazing of protozoa and its effect on populations of aquatic bacteria

MW Hahn, MG Höfle - FEMS microbiology ecology, 2001‏ - academic.oup.com

Predation as a sha** force for the phenotypic and genotypic composition of planktonic bacteria

K Jürgens, C Matz - Antonie Van Leeuwenhoek, 2002‏ - Springer
Predation is a major mortality factor of planktonic bacteria and an important sha** force for

Gross growth efficiencies of protozoan and metazoan zooplankton and their dependence on food concentration, predator‐prey weight ratio, and taxonomic group

D Straile - Limnology and Oceanography, 1997‏ - Wiley Online Library
A comprehensive dataset on the gross growth efficiency (GGE) of planktonic protozoans and
