Plasmid composition of Staphylococcus species

Canadian Journal of Microbiology, 1981
A total of 342 staphylococci representing 13 different recognized species were screened for plasmid composition using agarose gel electrophoresis techniques. Plasmids of molecular weight (MW) 30 × 106 or larger in size were uncommon in staphylococci.

Species Composition of the Forest

2003
One of the most striking features of tropical forests is their extraordinary species diversity (MacArthur 1969; Gentry 1982). The diversity of tropical trees supports a remarkable diversity of vertebrate and insect herbivores that have been shown to inflict a more intense pest pressure than in temperate settings (Landsberg and Ohmart 1989; Coley and ...

Composition and biosynthesis of molecular species of retina phosphoglycerides

Neurochemistry International, 1980
Recent studies on the fatty acid composition and labeling by glycerol of individual molecular species of retinal phosphoglycerides are presented. Docosahexaenoate-containing species are important constituents of retina phospholipids. 22:6 and saturated fatty acids appear in similar amounts in hexaenes (nearly 50% each).

Diversity and Composition of Plant and Lichen Species

2013
Abstract Among the elements of forest biodiversity, vegetation, including epiphytes, is the foundation of ecosystem functioning and primary production. Basic features for harmonized large-scale and intensive monitoring of vascular plants, cryptogams, and epiphytic lichens are presented. For the assessment of ground vegetation on the European scale, a

DNA base composition of species of the genusSaccharomyces

Antonie van Leeuwenhoek, 1975
DNA base compositions (GC content) of Saccharomyces species are reported and discussed. Several amendments of the four groups given by van der Walt are suggested, viz. the transfer of S. kluyveri to group 1, and of S. eupagycus, S. cidri, S. montanus, S. microellipsodes and S. florentinus to group 2. The synonomy of S. amurcae and S. cidri is suggested.

Mineral composition of basidiomes of Amanita species

Mycological Research, 2005
Basidiomes of 43 samples of eight Amanita species were gathered from different habitats of Hungary. The mineral composition (22 elements) was analysed by the ICP method in three independent replications, and mineral compositions found as discussed and compared.

Validation of the species composition index

Agricultural Systems, 1986
Abstract This paper is a validation of the Species Composition Index (SCI). The SCI is a data-handling technique which expresses the botanical composition of a sward as a vector. Inclusion of these vectors allows the incorporation, in response models, of the dynamic changes in species composition of sods which occur over time.

[Species composition of mycococci].

Mikrobiologiia, 1980
The phenotypical similarity between 34 microbial strains was determined, and they were classified on the principle of maximal general similarity in 70 traits. All the strains were subdivided into three groups within which the similarity of the strains was not less than 85%. The groups correspond to the species Mycococcus capsulatus, M.

Statistical Interpretation of Species Composition

Journal of the American Statistical Association, 2001
The relative abundance of different species characterizes the structure of a biological community. We analyze an experiment addressing the relationship between omnivorous feeding linkages and community stability. Our goal is to determine whether communities with different predator compositions respond similarly to environmental disturbance. To evaluate
