This publication provides a comprehensive review of the nomenclature and distribution of the Geadephaga of America, north of Mexico. Overall 2439 valid species-group taxa in 208 genera are catalogued along with their synonyms. Besides the usual information pertaining to author(s), date and page of publication, the type locality, location of name-bearing type, first reference establishing each synonym, and etymology for many patronymic names are provided for species-group names. Genus-group names are listed with the author(s), year of publication, page citation, type species with manner of fixation and etymology for most. The geographical distributions of all species-group taxa are briefly summarized and their state and province records are indicated. About 2500 references are listed with publication dates for many in order to assess priority of names.Several new nomenclatural acts are introduced including one new genus-group taxon, one new replacement name, three changes in precedence, five new genus-group synonymies, 65 new species-group synonymies, one new species-group status, and 12 new combinations.The work includes also a discussion of the notable private North American carabid collections, a synopsis of all extant world geadephagan tribes and subfamilies, a brief faunistic assessment of the fauna, a list of North American fossil Geadephaga, a list of North American Geadephaga larvae described or illustrated, a list of species described from specimens mislabeled as from North America, and a list of unavailable names listed from North America.

With the removal and destruction of natural areas for human use, there is a push to restore natural habitats. However, most restoration activities focus on reestablishing plant communities, while less is known about the recovery of organisms in higher trophic levels and their functional roles. Considering functional traits (those that explain an organisms' response to environmental change and impacts on ecosystems) of restored communities may reveal how communities, and the ecosystem functions they drive, recover. Of particular interest are ground beetles (Coleoptera: Carabidae) because of their diversity and important ecological roles as consumers. This study focused on the ground beetle community's taxonomic and functional responses to time since restoration, presence of bison, and prescribed fire to make predictions of how ground beetles influence restoration outcomes in tallgrass prairie. Specifically, the functional responses of interest were seed and arthropod predation. FDiv and FDis, two measures of functional diversity, were negatively affected by prescribed fire and presence of bison, but older restored sites had higher FDiv and FDis values. Predation rates, related to ecosystem functioning, also declined with recent fire. Older sites also had a higher activity density (abundance) of ground beetles, and bison created particularly favorable habitat for carnivorous and flightless species. While there was no clear pattern of how site age or bison impacted the ground beetle community, prescribed fire tended to reduce functional diversity and predatory function. Therefore, land managers should consider the timeframe between prescribed burns in order to allow the ground beetle community to reestablish, if the goal is to increase ground beetle community diversity and functional diversity.
