In nature, tadpoles encounter food on substrates oriented at different angles (e.g. vertically along stems, horizontally on the bottom of the pond). We manipulated the orientation of food-covered surfaces to test how ...

We had demonstrated that membrane adsorption or penetration differentially modulated β-Galactosidase (β-Gal) activity against soluble substrates (Coll. and Surf., 24, 21, 2002). In a heterogeneous media, not only the enzyme ...

The additive partition diversity has been a promising method to analyze patterns of diversity in hierarchical studies. Streams are recognized for having a spatial structure hierarchically organized in increasing scales, ...
