Feeding by the Pfiesteria-like heterotrophic dinoflagellate Luciella masanensis.
To explore the feeding ecology of the Pfiesteria-like dinoflagellate (PLD) Luciella masanensis (GenBank Accession no. AM050344, previously Lucy), we investigated the feeding behavior and the kinds of prey species that L. masanensis fed on and determined its growth and ingestion rates of L. masanensis when it fed on the dinoflagellate Amphidinium carterae and an unidentified cryptophyte species ...
متن کاملFerric iron reduction by acidophilic heterotrophic bacteria.
Fifty mesophilic and five moderately thermophilic strains of acidophilic heterotrophic bacteria were tested for the ability to reduce ferric iron in liquid and solid media under aerobic conditions; about 40% of the mesophiles (but none of the moderate thermophiles) displayed at least some capacity to reduce iron. Both rates and extents of ferric iron reduction were highly strain dependent. No a...
متن کاملGrowth, Grazing, and Starvation Survival in Three Heterotrophic Dinoflagellate Species.
To assess the effects of fluctuating prey availability on predator population dynamics and grazing impact on phytoplankton, we measured growth and grazing rates of three heterotrophic dinoflagellate species-Oxyrrhis marina, Gyrodinium dominans and Gyrodinium spirale-before and after depriving them of phytoplankton prey. All three dinoflagellate species survived long periods (> 10 d) without alg...
متن کاملPredation by the heterotrophic dinoflagellate Protoperidiniurn cf. divergens on copepod eggs and early naupliar stages
The heterotrophic dinoflagellate Protopemdinium cf. divergens, known as prey for adult copepods, itself feeds on copepod eggs and early naupliar stages. One to several P. cf. divergens can attack an egg or nauplius larger than themselves. The time for an egg to be digested was proportional to the number of P. cf. divergens attacking it. Ingestion rates of P, cf. djvergens on Acartia tonsa eggs ...
متن کاملFerrous Iron Is a Significant Component of Bioavailable Iron in Cystic Fibrosis Airways
UNLABELLED ABSTRACT Chronic, biofilm-like infections by the opportunistic pathogen Pseudomonas aeruginosa are a major cause of mortality in cystic fibrosis (CF) patients. While much is known about P. aeruginosa from laboratory studies, far less is understood about what it experiences in vivo. Iron is an important environmental parameter thought to play a central role in the development and main...
