DETECTING TRENDS IN SPECIES COMPOSITION

Ecological Applications, 1998
Species composition reflects a combination of environmental and historical events at a site; hence, changes in species composition can provide a sensitive measure of ecologically relevant changes in the environment. Here, we consider the analysis of species composition when multiple sites are followed through time.

Sphingolipid Composition in Bacteroides Species

Anaerobe, 1995
Sphingolipid profiles of strains from species of genus Bacteroides, and representative strains from Prevotella and Porphyromonas, were analyzed by thin-layer chromatography and infrared spectrophotometry. Two major types of phosphosphingolipid, ceramide phosphorylethanolamine and ceramide phosphorylglycerol, were detected in B. fragilis, B.

SAMPLING THE SPECIES COMPOSITION OF A LANDSCAPE

Ecology, 2002
The abundances and spatial distribution of species is central to biogeography and conservation. Several theories have been offered to explain landscape-scale species distribution patterns. The verification of biogeographic theories, as well as conservation decisions, must be based upon empirical data gathered from necessarily restricted censuses. It is

Tannin composition of barbatimão species

Fitoterapia, 2002
A comparative study of tannin composition of three species known as barbatimão (Stryphnodendron adstringens, Stryphnodendron polyphyllum and Dimorphandra mollis) was developed by TLC, hydrolysis followed by PC, and colorimetry. Principal component analysis of the data obtained showed strong differentiation between the genus Dimorphandra and ...
