Educational internationalism, universal human rights, and international organisation: International Relations in the thought and practice of Robert Owen
Robert Owen, the early nineteenth-century social reformer, made a greatly more significant contribution to the theory and practice of International Relations than has hitherto been assumed. This article shows how Owen helped to develop an understudied but distinctive form of internationalist thought focusing on the role of education in the pursuit of peace. Owen's previously neglected contributions to human rights norms and to international organisation are also explored, including his promotion of universal rather than nationally-oriented human rights standards, his role in the nascent movement towards the formation of international non-governmental organisations, and his contribution to international federalist ideas. Following an introduction to Owen's place in the literature, this article discusses each of these contributions of Owen to the theory and practice of International Relations in turn. The analysis reveals that Owen's contributions in each of these aspects are as significant for their limitations as for their insights
Conservation of Forest Birds: Evidence of a Shifting Baseline in Community Structure
Quantifying changes in forest bird diversity is an essential task for developing effective conservation actions. When subtle changes in diversity accumulate over time, annual comparisons may offer an incomplete perspective of changes in diversity. In this case, progressive change, the comparison of changes in diversity from a baseline condition, may offer greater insight because changes in diversity are assessed over longer periods of times. Our objectives were to determine how forest bird diversity has changed over time and whether those changes were associated with forest disturbance.We used North American Breeding Bird Survey data, a time series of Landsat images classified with respect to land cover change, and mixed-effects models to associate changes in forest bird community structure with forest disturbance, latitude, and longitude in the conterminous United States for the years 1985 to 2006. We document a significant divergence from the baseline structure for all birds of similar migratory habit and nest location, and all forest birds as a group from 1985 to 2006. Unexpectedly, decreases in progressive similarity resulted from small changes in richness (<1 species per route for the 22-year study period) and modest losses in abundance (-28.7 - -10.2 individuals per route) that varied by migratory habit and nest location. Forest disturbance increased progressive similarity for Neotropical migrants, permanent residents, ground nesting, and cavity nesting species. We also documented highest progressive similarity in the eastern United States.Contemporary forest bird community structure is changing rapidly over a relatively short period of time (e.g., approximately 22 years). Forest disturbance and forest regeneration are primary factors associated with contemporary forest bird community structure, longitude and latitude are secondary factors, and forest loss is a tertiary factor. Importantly, these findings suggest some regions of the United States may already fall below the habitat amount threshold where fragmentation effects become important predictors of forest bird community structure
