The Biology and Ecology of Tintinnid Ciliates:Models for Marine Plankton
Biology and Ecology Tintinnid Ciliates Marine Plankton

2015/7/16
Single-celled eukaryotes called protists are vitally important to marine ecosystems. Protists with chloroplasts (algae) carry out most of the primary production in the sea. What feeds on this algal pr...
Effect of zooplankton-mediated trophic cascades on marine microbial food web components (bacteria, nanoflagellates, ciliates)
zooplankton-mediated trophic marine microbial food

2014/4/17
To examine the grazing effects of copepod-dominated mesozooplankton on heterotrophic microbial
communities, four mesocosm experiments using gradients of zooplankton abundance were carried out at a
c...
Role of dispersal in shaping communities of ciliates and heterotrophic flagellates within riverine biofilms
Role of dispersal heterotrophic flagellates

We tested the role of immigration from the plankton on the structure of local surface-associated communities
of ciliates and heterotrophic flagellates (HF) in flow cells fed with fresh riverine water...
Light versus food supply as factors modulating niche partitioning in two pelagic mixotrophic ciliates

We studied the vertical distribution of two mixotrophic ciliates,Ophrydium naumanniandStentor araucanusin two contrasting summer seasons (strong vs. mild windy years) to determinewhether differences i...
Effect of pH on growth, cell volume, and production of freshwater ciliates, and implications for their distribution
pH on growth cell volume production freshwater ciliates

We investigated the effect of pH on growth, cell volume, and production of the freshwater ciliates Urotricha farcta, U. furcata, and U. castalia in laboratory cultures with Cryptomonas sp. as food. Ov...
Attachment to suspended particles may improve foraging and reduce predation risk for tintinnid ciliates
Attachment to suspended particles improve foraging reduce predation risk tintinnid ciliates

2014/5/19
We describe a new behavior of planktonic ciliates. The field-collected tintinnid Eutintinnus inquilinus attached with its lorica to a range of surfaces, including particulate aggregates. Most tintinni...
Evidence for constant and highly specific active food selection by benthic ciliates in mixed diatoms assemblages

2014/5/14
Observational and experimental studies have shown that phagotrophic ciliates are highly selective predators.
However, little is as yet known about the actual mechanisms involved in prey selection. We...
The trophic role of marine pelagic ciliates and heterotrophic dinoflagellates in arctic and temperate coastal ecosystems: A cross-latitude comparison
The trophic role of marine pelagic ciliates heterotrophic dinoflagellates in arctic temperate coastal ecosystems A cross-latitude comparison
<
2014/5/26
We compared seasonal studies of ciliates and heterotrophic dinoflagellates conducted in Disko Bay (West Greenland, ~69°N) and the Kattegat (Denmark, ~56°N). In both systems, ciliates and heterotrophic...
Influences of benthic boundary-layer flow on feeding rates of ciliates and flagellates at the sediment-water interface

Heterotrophic protists are integral to sedimentary food webs, but influences on their activities are poorly understood, especially the role of benthic boundary-layer flow. Effects of flow on ingestion...
