Oxygen isotope compositions were measured by ion microprobe in individual micrometer-sized quartz grains extracted from one aerosol sample collected on the Cape Verde Islands and from four surface samples (three soils and one sediment) representin...

Non-isotopic immunoassays for human tumor necrosis factor alpha (TNF alpha) and human interleukin-6 (IL-6) were established by employing the dissociation-enhanced lanthanide fluoroimmunoassay (DELFIA) system based on the time-resolved fluoroimmuno...

Individuals of Pontoscolex corethrurus Muller, a geophagous tropical earthworm, were fed with two soils that have P-sorption contrasting characteristics. Water-soluble and exchangeable-P contents increased significantly in casts produced after ing...

Genome sizes (nuclear DNA contents) were documented spectrophotometrically for 29 species of North American cyprinid fishes. The data were then merged with comparable genome size data (published previously) from an additional 20 North American cyp...
