This thesis is an effort to formalize and document some of the changes occuring in the Warwar Valley of Gongola State, Nigeria, West Africa. The documentation will comprise a photographic study over time accompanied by an ethnographic narrative. Information gathered from photographic images, field notes and the anthropological record will...

Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
For many decades, production and assembly lines have played an important role in industrial manufacturing systems. In particular, they have proved to be an efficient way to organize the production of high volume products in many industries. In their effort to improve the efficiency of production lines, researchers encountered two...

Hybridization has been identified as a significant factor in the evolution of plants as groups of interbreeding species retain their phenotypic integrity despite gene exchange among forms. Recent studies have identified similar interactions in animals; however, the role of hybridization in the evolution of animals has been contested. Here we...

Background:
Phylogeographic studies of aquatic insects provide valuable insights into mechanisms that shape the genetic structure of communities, yet studies that include broad geographic areas are uncommon for this group. We conducted a broad scale phylogeographic analysis of the least salmonfly Pteronarcella badia (Plecoptera) across western North America. We tested...
