Abstract: The affects of zebra mussels in freshwater systems in North America have been well documented—particularly on native mussels (the St. Croix has 40 species). In 1992, the first zebra mussels were discovered in the Mississippi above the confluence with the St. Croix River, but reproduction was not pinpointed in the St. Croix until 2000. The NPS has gathered information about the population age structure of St. Croix zebra mussels to determine recruitment, growth rates, and mortality. Anecdotal accounts of periodic, but substantial zebra mussel die-offs in large river systems have been recently noted suggesting an early season recruitment followed by a late season population crash. These observations have been casual and not systematically well documented. In order to predict impacts to river biota, an organized assessment of seasonal population dynamics of zebra mussels in a large river system is necessary. The St. Croix River is a 6th order system with various zebra mussel infestations within the downstream most 22 miles, however in 2007, densities of this invasive animal reached over 12000m2 within the last 6 miles. If conditions in certain rivers allow for veliger settlement and establishment, but mussels cannot mature, implications for management are numerous.

Abstract: Social psychology has largely remained on the periphery of the discussion of nationalism, due, in part, to its tendency to gloss over the nation in pursuit of more general phenomena such as intergroup comparison. While few researchers report any problems with the term itself, it is widely agreed that concrete manifestations of nationalism are notoriously difficult to obtain for empirical study. Moreover, such an exercise is seen as futile because nationhood is thought to derive from the imagination of those who consider themselves part of a common national community. However, large public gatherings can create an opportunity to anchor the national imagination through the employment of symbols and national icons, invoking a sense of shared past and common destiny. The present study takes as an example the St Patrick’s Day celebrations in Dublin: the largest public display of nationalism in Ireland. The content of participants' national imaginings were obtained through photo elicitation interviews (PEI) and the active re-construction of the crowd event. The data reveal that crowd events form an arena in which to foster a sense of comradeship and common purpose in order to serve contemporary interests. This can be seen to mask the actual inequality and exploitation that exists beyond the realm of national imagination, in the reality of the social world.
