Morgan's three students (Muller, Sturtevant, and Bridges) introduced reductionist empirical methods to the study of the chromosomal theory of heredity. Herman J. Muller concentrated on mutations, namely changes in the heterocatalytic properties of genes, without losing their autocatalytic (self-replication) properties. Experimental induction of mutations allowed quantitative analyses of genes' ...
In the emerging area of nanotechnology, a key issue is related to the potential impacts of the novel nanomaterials on the environment and human health, so that this technology can be used with minimal risk. Specifically designed to combine on a single structure multipurpose tags and properties, smart nanomaterials need a comprehensive characterization of both chemicophysical properties and adeq...
This research aimed to determine the soil seed bank and its relationship with environmental factors that have an influence in the distribution of the vegetation above the ground in an excluded area of natural grassland in the South of Brazil. Most of the 122 identified species in the seed bank were perennials. Data analysis indicated three distinct community groups, according to the size and co...
