Purpose The purpose of this work was to determine the pro-and anti-inflammatory properties of the single-cell organism Euglena gracilis (EG) and various fractions of its whole biomass. Methods Heterotrophically grown EG was tested, along with its aqu

Summary Seston availability and quality can affect the condition, nutrient stoichiometry and nutrient excretion of dreissenid mussels and other aquatic consumers. Nutrient excretion by dreissenid mussels may affect phytoplankton community composition

This 42-day study evaluated the effects of dietary supplementation with β-1,3-glucan (Aleta™) on the vaccination response to Newcastle disease virus (NDV), avian infectious bronchitis virus (IBV), and infectious bursal disease (IBD) in a non-chall

This study determined the effect of a dried algae product containing beta-1,3-glucan on broiler performance and immunity during an Eimeria challenge. Heterotrophically grown Euglena gracilis, which contained ∼55% beta-1,3-glucan, was dried and mill

An important objective in understanding harmful phytoplankton blooms is determining how environmental factors influence the toxicity of bloom-forming species. We examined how nutrients and grazers (dreissenid mussels) affect the production of microcy

We tested the hypothesis that zebra mussels ( Dreissena polymorpha ) have positive effects on the toxin-producing cyanobacterium, Microcystis aeruginosa , at low phosphorus (P) concentrations, but negative effects on M. aeruginosa at high P, with a l

An important goal of coral reef ecology is elucidating the factors driving the distribution of corals, and to this end much attention has focused on disturbances and biotic agents. In this study, small-scale variations in the abiotic characteristics

An existing volunteer monitoring network in the state of Michigan was exploited to conduct a statewide survey of the cyanobacterial toxin, microcystin, and to test hypotheses about the interactive influences of eutrophication and dreissenid mussel in

Lakes in carbonate-rich watersheds commonly precipitate calcium carbonate as calcite, and this is accelerated by photosynthetic uptake of carbon dioxide. Co-precipitation of phosphate with calcite is one reason that algal growth in such lakes tends t
