A PLANT TRAIT-BASED APPROACH TO EVALUATE THE ABILITY OF NATIVE C\u3csub\u3e3\u3c/sub\u3e AND C\u3csub\u3e4\u3c/sub\u3e GRASSES TO RESTORE FUNCTIONALITY TO A REMNANT BLUEGRASS SAVANNA-WOODLAND IN KENTUCKY, USA.

Temperate Midwestern oak savannas are considered imperiled ecosystems with \u3c 1 % remaining since the time of European settlement and are identified as critical areas for preservation. Restoration of Midwestern oak savannas is challenging due to the lack of accurate historical data, few intact remnants remaining to study, and lack of restoration ecology studies. A plant trait-based approach was used to evaluate the ability of six C3 and three C4 native bunchgrasses to restore functionality to a remnant savanna–woodland of the Bluegrass Region of Kentucky. The response and effect framework was used to assess the response of the nine native grasses according to the habitat filters of interannual precipitation, inter- vs. intra-specific competition, and simulated grazing. The effect traits associated with plant-soil nitrogen and carbon cycling were also assessed. The response traits of interannual competition and inter- vs. intra-specific competition along with the effect traits plant-soil nitrogen and carbon cycling were measured in a monoculture experiment conducted at Griffith Woods WMA. The simulated grazing or clipping experiment was conducted over three months in a heated greenhouse experiment. Four of the C3 species were of the genus Elymus which had significant differences in life history traits compared to the other species and made them particularly well adapted to the Bluegrass Savanna-Woodland. The Elymus species were not well adapted to the most intense clipping treatment. For the other two C3 species, C. latifolium would be a better competitor than D. clandestinum under normal conditions. D. clandestinum had the most number of plastic traits and was the only species to exhibit all three grazing strategies. Comparing the C4 species, T. flavus and P. anceps grew well in the monoculture but A. virginicus did not. The life history traits of A. virginicus does not make this species a good candidate for restoration at this site. The three C4 species were well adapted to clipping. The results of this study suggest that the C3 species, particularly the Elymus, are well adapted to the eutrophic mesic conditions of the Bluegrass Savanna-Woodland, and that the C4 species are better adapted to disturbance

Observations on the state of comparative administration research in Europe : more comparable than comparative

This article tries to review public administration research undertaken in Europe since about 1980. As there is little comparative research, an attempt is made to systematize comparable research along three dimensions: organization structures (macro and micro), meta-policymaking as it refers to budgeting and planning procedures, and research about personnel and personnel policy. It is obseroed that neo-conseroative reform policies in the Anglo-American countries have had a noticeable impact on the orientation of academic research. Subsequently, these policies not only affected macro-structures by privatization and decentralization measures, but also gave meta-policymaking a characteristic turn, quite as it tried to induce a more managerialist role understanding in the civil seroice. It is argued in favor of more basic research and the institutionalization of administrative monitoring on the national level as well as stronger cooperation on the international level to advance comparative research beyond secondary analysis of the incidentally comparable
