Supervariate Gel Transforms into Various Biominerals in Salt Solutions
It is revealed that common calcium‐based biominerals can form from a stable, non‐toxic ‘supervariate’ gel. This tunable gel selectively yields calcite or hydroxyapatite in carbonate/phosphate solutions, while CaCl₂ facilitates the formation of dihydrate calcium pyrophosphate, which converts to hydroxyapatite upon drying. These findings provide insights

The Measurement of Species Diversity
Annual Review of Ecology and Systematics, 1974Inspired significantly by the provocative papers of MacArthur (34, 35, 38) and Hutchinson (22), ecologists over the past twenty years have devoted considerable energy to the explanation of patterns of diversity in ecologic systems. Despite considerable interest, however, no generally accepted definition of diversity has emerged.
