the islamic revolution helped develop a new discourse and semantic system. one of the methods to study or analyze the political phenomena is critical discourse analysis namely, that of laclau and mouffe›s discourse, the most pertinent. this article examines its main question whether the values of the islamic revolution concepts and identity are constructed, spread and articulated according to l...

We studied short-term (1–3 years) responses of plant species and functional group abundances, richness, evenness, diversity, and similarity following cessation of 25 years (1972–1997) of herbicide application in a remnant of Blackland Tallgrass Prairie in central Texas. Substantial increases in plant cover from 1998 to 2000 were observed for annual forbs (359%–900%), primarily attributable to f...

We used 7 years of live-trapping data from an Illinois population of prairie voles to examine how survival and reproductive success varied with size and composition of social groups. Specifically, we examined measures of fitness for residents of single female units, male–female pairs and communal groups. Reproductive success, measured as either the number of young that survived to 12 or 30 days...

Social behavior of the prairie vole, Microtus ochrogaster, including monogamy, mate guarding, philopatry, communal nesting, and territoriality, evolved as an adaptation to habitats with low food prevalent in the original range of the species. These behaviors are associated with low population densities and low amplitudes of fluctuation characteristic of low food habitats. In particular, reprodu...

of their natural distributions in southern Alberta, Canada. In this semi-arid area, poplars are obligate riparian species but they occupy several intergrading ecoregions. Populus deltoides Bartr. ex Marsh predominates in the warmest and driest eastern prairie ecoregions; P. balsamifera L. occupies the cooler and wetter western parkland and montane ecoregions; and P. angustifolia James and hybri...

I compared growth and arbuscular mycorrhizal fungal (AMF) colonization of two prairie grasses (Wild rye [Elymus canadensis] and Little bluestem [Schizachyrium scoparium]), an earlyand a late-dominating species in prairie restorations, respectively, grown in soil from restored prairies of differing age, soil characteristics, and site history. There were no consistent patterns between restoration...

L-band brightness predicted by the land surface process/radiobrightness (LSP/R) model for prairie grassland appears to be somewhat lower than expected [1]. A crucial reason for the underestimate of the L-band brightness is that the soil surface was treated as smooth. In this paper, surface scattering of the soil determined by the IEM model is incorporated into the LSP/R model to examine its imp...

INTRODUCTION Many tracts of native vegetation still remain in the western portion of that vast North American grassland known as True Prairie. Some are mowed annually for the crop of excellent forage, but far greater areas are now in native pasture (Weaver & Fitzpatrick 1932, 1934). One result of the long years of study of the grazed portion of this grassland was the recognition of the manner i...
