Spatial patterns of planktonic ciliate communities for assessment of marine environmental status were studied from June 2007 to May 2008 in Jiaozhou Bay, Qingdao, northern China. Ciliate communities were sampled biweekly at five sampling sites with a spatial gradient of environmental stress. Multivariate/univariate analyses demonstrated that: (1) the(More)
The morphology and morphogenesis of the stylonychine hypotrich Rigidohymena candens (Kahl, 1932) Berger, 2011, isolated from garden soil in Qingdao, China, were investigated using live observation and protargol impregnation methods. The Qingdao isolate possesses all diagnostic morphological characters of R. candens. The main events during binary fission are(More)
INTRODUCTION In order to reveal the potential relationships between body-size patterns of microzooplankton and environmental status, the spatial patterns in body-size spectra of ciliated zooplanktons were studied based on an annual dataset in a bay of the Yellow Sea, northern China. MATERIALS AND METHODS A total of 120 samples were collected at a depth of(More)
The morphology and infraciliature of two novel marine scuticociliates, Metanophrys orientalis spec. nov. and Uronemella sinensis spec. nov., collected from sandy beaches at Qingdao, China, were investigated using live observation and protargol-staining methods. Metanophrys orientalis spec. nov. is distinguished by the following characteristics: marine(More)
A new approach to determining sampling effort for analyzing biofilm-dwelling ciliate colonization was studied in the coastal waters of the Yellow Sea, northern China, from May to June 2010. The optimal sample size for evaluating biofilm-dwelling ciliate colonization increased with shortening exposure time, and can be determined according to the probability(More)
INTRODUCTION In order to identify a potential surrogate of planktonic ciliate communities for marine bioassessments and evaluating biological conservations, the different taxonomic/numerical resolutions and taxa as surrogates were studied in Jiaozhou Bay, northern China during a 1-year cycle (June 2007-May 2008). MATERIALS AND METHODS Samples were(More)
INTRODUCTION With quick responses to environmental changes, easy sampling, relative immobility, increasing availability of easily used taxonomic references, and allowing standardization for temporal and spatial comparisons, the biodiversity measures of microperiphyton communities have widely been accepted as useful indicators to evaluate environmental(More)
The living morphology and infraciliature of a new marine hypotrichous ciliate, Holosticha bradburyae nov. spec., collected from the coastal water off Qingdao (Tsingtao), China, are investigated. This species is characterized by: body size 150–320 × 25–75 μm with brownish to dark brown cell colour, ca. 53 adoral membranelles and 1 anteriorly positioned(More)
The morphology and morphogenesis of the large marine heterotrichous ciliate, Condylostoma spatiosum Ozaki & Yagiu in Yagiu, 1944, isolated from Jiaozhou Bay off Qingdao (Tsingtao), China, were investigated using live observation and protargol impregnation. A detailed redescription is given since no infraciliature data about this "well-studied" species are(More)
Colonization features and taxonomic relatedness measures of ciliate communities have been used as useful indicators for marine bioassessment. The influence of enumeration time periods on analyzing colonization features measures of periphytic ciliate communities was studied in coastal waters of the Yellow Sea, northern China, during the period of May-June(More)
