Soil moisture controls environmental processes and species distributions, but it is difficult to measure and interpolate across space. Topographic Wetness Index (TWI) derived from digital elevation model is therefore often used as a proxy for soil ...

Sphingolipid Composition in Bacteroides Species
Anaerobe, 1995Sphingolipid 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, 2002The 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, 2002A 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 ...

Spatial heterogeneity in species richness and species composition
Grassland Science, 2010AbstractVisually detecting and measuring actual spatial heterogeneity is relatively easy using traits of grassland vegetation communities, e.g. ‘quantitative’ traits such as spatial heterogeneity in biomass, vegetation cover and frequency of occurrence for each species. In the present paper, we consider substantively ‘qualitative’ aspects of vegetation,

Unmanned aerial vehicle methods makes species composition monitoring easier in grasslands
Ecological Indicators, 2018Species composition plays a critical role in environmental conservation, ecosystem functioning and health of grasslands. However, there is no efficient and long-term monitoring method.

Lipid composition of 30 species of yeast
Lipids, 1976AbstractThe detailed composition of cellular lipid of more than 23 species of yeast has been determined quantitatively by thinchrography on quartz rods, a method previously used for estimating cellular lipids of seven species of yeast. That data was fortified by neutral and phospholipid quantitations on 30 species of yeast cells.
