The Great Lakes Fishery Commission has traditionally supported the conservation of genetic diversity native to the Great Lakes, and counseled caution in adding new species to the Great Lakes aquatic community. Since extinction of sub-specific taxa and establishment of new species in the Great Lakes have proven irreversible, caution and conservatism are warranted. The Commission's mandate has served the Great Lakes well in preventing, controlling, and managing exotics. For example, the Commission (1) provides a forum for interjurisdictional consultation prior to planned introduction of new fish species; (2) represents fishery agency concerns for inadvertent introductions to outside interests, as in the case of ship ballast introductions; (3) champions the conservation of genetic diversity native to the Lakes; and (4) controls the exotic sea lamprey at levels which permit fishery agencies to attain their fish community objectives.

The ancient Romans famously distinguished between civic life in Rome and military matters outside the city—a division marked by the pomerium, an abstract religious and legal boundary that was central to the myth of the city's foundation. This book explores, by means of images and texts, how the Romans used social practices and public monuments to assert their capital's distinction from its growing empire, to delimit the proper realms of religion and law from those of war and conquest, and to establish and disseminate so many fundamental Roman institutions across three centuries of imperial rule. The book probes such topics as the appearance in the city of Romans in armor, whether in representation or in life, the role of religious rites on the battlefield, and the military image of Constantine on the arch built in his name. Throughout, the book reveals how, in these instances and others, the ancient ideology of crossing the pomerium reflects the efforts of Romans not only to live up to the ideals they had inherited, but also to reconceive their past and to validate contemporary practices during a time when Rome enjoyed growing dominance in the Mediterranean world. The book explores a problem faced by generations of Romans—how to leave and return to hallowed city ground in the course of building an empire.
