Racial Identity Among Mixed Adolescents in Hawaii: A Research Note

The islands of Hawaii are well-known for their unique level of racial heterogeneity and admixture, overt norms of racial tolerance and harmony, and temperate climate. Of central interest to the social scientist is the manner in which racial and cultural blending take place in such a complex society, particularly among those of mixed racial origin; Hawaii provides a social laboratory in which to study such processes in depth. This paper, viewing racial identity as an important index of intergroup relations, examines the racial identities and related reasons of forty high school adolescents in Hawaii in order to highlight controlling factors of the social environment

Soil seed banks of fringing salt lake vegetation in arid Western Australia - density, composition and implications for postmine restoration using topsoil

Although studies of seed banks in arid ecosystems are commonplace, they are lacking for the large arid zone of Western Australia. Across the six major plant communities fringing a large salt lake within this zone, topsoil (0-5 cm depth) was collected from 12 to 36 sites per community. Samples were dried, spread out on a bed of vermiculite in seedling trays and placed in a well-watered glasshouse to determine the readily germinable component of the soil seed bank. Subsamples of topsoil were treated with smoke water, hot water or flooding to help determine seed bank of species with dormancy mechanisms. As with other studies of arid seed banks, large numbers of grasses and forbs emerged from the topsoil, with relatively small numbers of woody perennial species and hummock grasses (Triodia spp.) present, even in communities where such species were dominant. There were, however, a few exceptions where a reasonable density of dominant trees/shrub seed was present in topsoil. Soil treatment generally had limited effect on composition and density of emergent seedlings. Although floristic similarity between soil seed banks and corresponding above-ground vegetation was modest, there were clear differences in soil seed bank composition between communities. The implications of the results for using topsoils to restore landforms of the study area after mining or other disturbance are discussed
