In situ growth rates of interstitial ciliates of a sandy hyporheic zone were determined by a modification of the dilution technique. Preconditioned sediment was used as a dilution substrate. Field incubation was conducted in the upper 3 cm sediment layer; samples were taken on 3 days (Days 0, 21 and 35) in October to November 2002. Mean growth rates varied between 0.070 d–1 (Pleuronema spp.) an...

The present research explores the relationship between the two components of autobiographical memory--episodic and semantic self-knowledge--and identity strength in older adults living in the community and residential care. Participants (N= 32) completed the autobiographical memory interview and measures of personal identity strength and multiple group memberships. Contrary to previous research...

We report an in-depth survey of next-generation DNA sequencing of ciliate diversity and community structure in two permanently ice-covered McMurdo Dry Valley lakes during the austral summer and autumn (November 2007 and March 2008). We tested hypotheses on the relationship between species richness and environmental conditions including environmental extremes, nutrient status, and day length. On...

A new species of Stenolemus Signoret, 1858, Stenolemus annulatus sp. nov. (Reduviidae: Emesinae) is described from India. This new species is closely related to S. susainathani Wygodzinsky from Nilgiri Hills, South India and S. larat Wygodzinsky from Moluccas, Larat, by sharing common characteristics such as the ratio of distance between eyes and their width, long antennal first segment, slight...

where (v,1, ..., v,,) is a given probability vector, and (Xt(x), Yl(x)), ..., (X.(x), Y,(x)) is a permutation of (X1, I71) . . . . , (X, , Y,) according to increasing values of IlXi-x[I, x e R a. When [IXi-xll = H X j x l [ but i < j , X i is said to be closer to x than X~. The consistency properties of m, for special choices of the weight vector (v,,, ..., v,,,) are discussed in Cover (1968), ...

Peritrich ciliates are commonly found as epibionts, colonizing living organisms, or attached to non-living substrates in freshwater, estuarine and marine environments. Several species of peritrich epibionts are obligate, which means that they are able to only colonize other organisms, while others are facultative attaching to living or non-living substrates. The peritrich Zoothamnium intermediu...

High concentrations of the ciliate Epidinium Crawley are associated with damaged regions of fresh plant material undergoing digestion in the sheep rumen. This finding supports that postulate that sequestration in the rumen explains the low rate of passage of protozoa despite the high flow rate of liquid from the rumen. The maintenance of Epidinium in the rumen, despite their slow growth rate, i...
