Local ciliate communities associated with aquatic macrophytes [PDF]

open access: yes, 2014
This study, based within the catchment area of the River Frome, an important chalk stream in the south of England, compared ciliated protozoan communities associated with three species of aquatic macrophyte common to lotic habitats: Ranunculus ...

Bioavailability and trophic transfer of humic-bound copper from bacteria to zooplankton [PDF]

open access: yes, 1999
: The effect of humic acid (HA) on uptake and transfer of Cu by selected marine organisms from the microbial loop was determined. Bacteria grown with and without 15 µg Cu l-1 and with and without 10 mg Suwannee River Humic Acid (SRHA) l-1 were fed to ...

SPECIES COMPOSITION OF PSAMMOPHILIC CILIATES OF SUMGAIT CASPIAN COAST

open access: yesЮг России: экология, развитие, 2014
. Comparative data on the species composition and species saprobic indicators of the psammon ciliates from Sumgait coast of the Caspian Sea are given.Methods. “Alive” samples were collected using a small clean plastic wide mouth bottles.

Novel insights into the genetic diversity of Balantidium and Balantidium-like cyst-forming ciliates [PDF]

open access: yes, 2013
Balantidiasis is considered a neglected zoonotic disease with pigs serving as reservoir hosts. However, Balantidium coli has been recorded in many other mammalian species, including primates. Here, we evaluated the genetic diversity of B.

Effect of zooplankton-mediated trophic cascades on marine microbial food web components (bacteria, nanoflagellates, ciliates) [PDF]

open access: yes, 2009
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 coastal marine site.

High infestation and phylogenetic position of Epistylis sp. (Ciliophora, Peritrichia) on Aegla serrana Buckup & Rossi (Crustacea, Anomura) from southern Brazil [PDF]

open access: yesAnais da Academia Brasileira de Ciências
High infestations of epibiont ciliates on vertebrates or invertebrates are normally related to aquaculture tanks or similar environments, and the importance of this relationship in natural habitats is often disregarded. Here, we describe the first record

Neglect of Presence of Bacteria Leads to Inaccurate Growth Parameters of the Oligotrich Ciliate Strombidium sp. During Grazing Experiments on Nanoflagellates

open access: yesFrontiers in Marine Science, 2020
Oligotrich ciliates play a key role in linking microbial food webs to the traditional grazing food chain. Hence, the numerical (growth) and functional (grazing) responses of oligotrich ciliates are very important issues in studies of marine ecosystems ...

Ciliados (Protozoa) de sedimentos secos de una charca temporaria de la Argentina [PDF]

open access: yes, 2009
Temporary ponds represent special environments that are inhabited by organisms adapted to changing environmental conditions. Ciliates are able to survive complete loss of water in these transient habitats through cyst formation. Nevertheless, ciliates
