Soils contain the largest pool of carbon that is actively cycling on human timescales, leading many to view soils as a natural climate solution with multiple co-benefits. The field of soil science is rapidly evolving, but without a unified understanding of soil carbon dynamics. This dissertation leverages two distinct long-term...
Dielectrophoresis (DEP) is a separation method in which a non-uniform electric
field is used to induce a dipole moment in a suspended particle. If the polarization
of the particle is greater than that of the suspending medium, the particle will move
towards the region of higher field strength (positive DEP);...
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants and are mostly products of the incomplete combustion of organic material. PAHs are often found in environmental samples as a complex mixture of isomers. In addition, the same sources that produce complex PAH mixtures also produce other poorly characterized mixtures of organic compounds,...
This thesis presents a discussion of the main materialistic theories proposed to explain the process of development among the indigenous population of Latin America. Four theoretical approaches are presented and discussed. The first one deals with the social group referred to as peasants. The second one explains the process of...
Aim: The ecological effects of biological invasions are well documented, but little
is known about the effects of invaders on the genetic structure of native
species. We examined the phylogeography, genetic variation and population
structuring of two galaxiid fishes, Aplochiton zebra and A. taeniatus, threatened
by non-native salmonids, and whose...
