مصطلحات موضوعية: Democracia deliberativa, Meios de comunicação social, Retórica, Argumentação, Referendo, This study analyzes and compares the material published by two newspapers – Folha de São Paulo, from Brazil, and Público, from Portugal, on the referendums that happened in both countries in 2005 and 2007 respectively. The purpose is verifying whether in this material there are discourses with arguments that might be considered useful to a deliberative process, in the perspective of democracy as it is defended by Jürgen Habermas. According to Simone Chambers, newspaper material is classified as either plebiscitary rhetoric or deliberative rhetoric. The former is characterized by the presence of more elements that do not contribute for the attainment of a public deliberation, whereas the latter contains significant presence of elements considered important for the development of this process. The reinforcement of some of its elements in the newspaper materials – this investigation assesses and quantifies which elements are privileged by the media – may bring it closer or apart of what is considered important for a public debate in a habermasian perspective. The decision on privileging one or another element is a choice that the media makes. Upon choosing, it leaves the border area, with many open possibilities, and starts a demarcation process. When it demarcates, it sets limits for either process. Taking into consideration that the media has ambivalent potentials, this investigation makes this assumption: it is not possible to define the role that the media plays in specific events of public deliberations, such as referendums, because in its material all the rhetoric elements are present, both those favoring and impairing the deliberative process. Nevertheless, given its production and publicizing reasoning, it reveals some of the limits that prevent it from complexifying the public agenda themes. The assumption made here is that its choices privilege the rhetoric elements that are in consonance with the logic of evidence, which is refractory to an argumentative process. It is temerarious to consider the media as a central forum for public deliberation because it privileges more elements that limit an argumentative process. If its power of scope may be taken as something potentially useful for carrying out deliberative processes in contemporary democracies, the mere availability of this apparatus does not allow us to jump to conclusions that its practice effectively contributes for the development of public debate. For its potential, and also for allowing that inside it also circulates material identified with a deliberative rhetoric, one could even see the media as a player able to play a complementary role, but not a central one, in the broader process of public deliberation. Under this light, one cannot dismiss completely the possibility that the material produced by the media triggers a deliberative process in society when it is appropriated of or reinterpreted in several ways by the various players of the public scope

جغرافية الموضوع: operated by the U.S. Fish & Wildlife Service, where the grassland plots are located, is of course dominated by black grama (Bouteloua eriopoda). Other highly prevalent grasses include Sporabolus contractus, S. cryptandrus, S. flexuosus, dominantly Gutierrezia sarothrae, Ephedra torreyana, Krascheninnikovia lanata, Opuntia imbricata

الوقت: * Sevilleta LTER Project Area Description (from the Phenology metadata) The Sevilleta National Wildlife Refuge, operated by the U.S. Fish & Wildlife Service, is located in Socorro County in central New Mexico. The Sevilleta spans approximately 100,000 ha of land and has vegetative influences representative of the Chihuahuan Desert, the Great Plains grassland and the Colorado Plateau. * Study Area Description (summarized from the Sevilleta LTER website) The Black Grama Core site, where the grassland plots are located, is of course dominated by black grama (Bouteloua eriopoda). Other highly prevalent grasses include Sporabolus contractus, S. cryptandrus, S. flexuosus, Muhlenbergia aernicola and Bouteloua gracilis. There is also a significant presence of shrubs, dominantly Gutierrezia sarothrae, along with less abundant Atriplex canescens, Ephedra torreyana, Krascheninnikovia lanata, Opuntia imbricata, O. clavata, O. phaeacantha, Yucca glauca and what are presumed to be encroaching, yet sparsely distributed, creosote (Larrea tridentata). Notable forb species included Allionia incarnata, Astragalus missouriensis, Chamaesyce serrula, Cryptantha crassisepala, Descarania obtusa, Plantago patagonica, Sphaeralcea wrightii, and Tidestromia lanuginosa. The Creosote Core site, where the shrubland plots are located, is characterized as Chihuahuan Desert Scrub dominated by a creosote bush overstory. Other common shrubs include Gutierrezia sarothrae, Opuntia macrocentra, and Yucca glauca. The site is also characterized by numerous dense, grass-dominated patches, reflecting proximity to the Black Grama Core site and the presumably recent appearance of creosote bush. Dominant grasses include Bouteloua eriopoda, Dasyochloa pulchellum, Scleropogon brevifolia, Muhlenbergia porteri, and Pleuraphis jamesii. Notable forb species included Bahia absinthifolia, Chaetopappa ericoides, Hoffmannseggia glauca, Lesquerella fendleri, Cryptantha crassisepala, and Spaeralcea wrightii. The mixed plots are located in an ecotone reflecting the transition between the sites described above. Larrea tridentata and Bouteloua eriopoda are both common at the mixed plots site. Another common grass at this site is Muhlenbergia arenicola. Common forbs include Physalis integrifolia, Plantago patagonica, Linum puberulum, and Astragalus missouriensis var. mimetes. In general the ecotone site is less diverse than either the Black Grama Core Site or the Creosote Core Site., 2005

الوقت: Site Location: The Blue Grama Core Site is one of 5 current core SEVLTER study sites. Core studies include meteorology, rodent abundance, pollinator diversity, monthly phenology, and NPP. Additional studies have examined the Bootleg Canyon fire of 1998 and grass patch dynamics. Vegetation: Vegetation is characterized as Plains-Mesa Grassland, dominated by blue and black gramma (Bouteloua gracilis and B. eriopoda) and galleta grass (Hilaria jamesii), Site Location: The Pinyon-Juniper Core Site, or Cerro Montoso has been the focus for SEVLTER studies since 1989. Meteorology, NPP, rodent and ground-dwelling arthropod populations, pinyon and juniper mycorhizal response to fertilizer, pinyon-juniper fruit and nut production, and an assessment of pinyon mortality are ongoing studies at the site. Previous studies included analysis of pinyon tree rings for regional historical climate reconstructions. Vegetation: The vegetation is classic New Mexico Pinyon-Juniper Woodland, dominated by Colorado pinyon (Pinus edulis) and one-seed juniper (Juniperus monosperma), accompanied by gray oak (Quercus grisea), as well as a diverse shrub component including scrub liveoak (Q. turbenela), mountain mahogany (Cercocarpus montanus), broom snakeweed (Gutierrezia sorothrae), sacahuista (Nolina microcarpa), algerita (Mahonia haematocarpa), Apache plume (Falugia paradoxa), tree cholla (Opuntis imbricata), skunkbush (Rhus trilobata) and banana yucca (Yucca baccata). Grass diversity is also high, and open spaces between trees are dominated by blue grama (Bouteloua gracilis), with hairy, sideoats (B. hirsuta, B. curtipendula), and black grama (B. eriopoda) also significant. Other common grasses included purple threeawn (Aristida purpurea), wolftail (Lycurus phleoides), mountain and ring muhly (M. montanus and M. torreyi), and New Mexican porcupinegrass (Stipa neomexicana). Common forbs included Nuttal loco (Astragalus nuttallianus), Louisiana sage (Artemesia ludoviciana), Fendlers arabis (Arabis fendleri), Fendlers sandmat (Chamaesyce fendleri), New Mexico thistle (Cirsium neomexicanum), False pennyroyal (Hedeoma oblongifolia), bastard sage (Eriogonum wrightii), Pinge bitterweed (Hymenoxys richardsonii), large four oclock (Mirabilis multiflora), Fendler penstemon (Penstemon fendleri), and globemallow (Sphaeralcea hastulata and S. wrightii)., Site Location: Five Points is the general area which emcompasses the Black Grama Grassland (known as Five Points Grassland) and Creosote Core (Five Points Larrea) study sites and the transition between Chihuahuan Desert Scrub and Desert Grassland habitats. Both core sites are subject to intensive research activities, including measurements of NPP, phenology, pollinator diversity, and ground dwelling arthropod and rodent populations. There are drought rain-out shelters in both the Grassland and Creosote sites, as well as another set in the mixed ecotone with co-located ET Towers. The grassland Small Mammal Exclosure Study is located here, as well as many plots related to patch mapping and biotic transitions. Vegetation: Desert Grassland habitat is ecotonal in nature and the Black Grama Core site is no exception, bordering Chihuahuan Desert Scrub at its southern boundary and Plains-Mesa Grassland at its northern, more mesic boundary. There is also a significant presence of shrubs, dominantly broom snakeweed (Gutierrezia sarothrae), along with less abundant fourwing saltbush (Atriplex canescens), Mormon tea (Ephedra torreyana), winterfat (Krascheninnikovia lanata), tree cholla (Opuntia imbricata), club cholla (O. clavata), desert pricklypear (O. phaeacantha), soapweed yucca (Yucca glauca), and what are presumed to be encroaching, yet sparsely distributed, creosotebush (Larrea tridentata). Characteristically, the dominant grass was black grama (Bouteloua eriopoda). Spike, sand, and mesa dropseed grasses (Sporobolus contractus, S. cryptandrus, S. flexuosus) and sand muhly (Muhlenbergia arenicola) could be considered co-dominant throughout, along with blue grama (B. gracilis) in a more mesic, shallow swale on the site.

Characteristically, the dominant grass was black grama (Bouteloua eriopoda). Spike, sand, and mesa dropseed grasses (Sporobolus contractus, S. cryptandrus, S. flexuosus) and sand muhly (Muhlenbergia arenicola) could be considered co-dominant throughout, along with blue grama (B. gracilis) in a more mesic, shallow swale on the site. Notable forb species included trailing four oclock (Allionia incarnata), horn loco milkvetch (Astragalus missouriensis), sawtooth spurge (Chamaesyce serrula), plains hiddenflower (Cryptantha crassisepala), blunt tansymustard (Descarania obtusa), wooly plaintain (Plantago patagonica), globemallow (Sphaeralcea wrightii), and mouse ear (Tidestromia lanuginosa)., Site Location: Rio Salado is about 3 km West I-25 just south of the Rio Salado. Site is accessed by taking San Acacia exit, going west and then taking the frontage road back north to the Sevilleta gate. After entering the refuge turn left after about .2 mi and take this road about 1.4 mi to a T in the road at the power lines. An earthen berm stops road travel here and the station is located about 300 m west on the blocked road., 1995-10-04 to 2005-09-24

مصطلحات موضوعية: SEV, Sevilleta National Wildlife Refuge, New Mexico, LTER, Vegetation, line-intercept

جغرافية الموضوع: including measurements of NPP, phenology, pollinator diversity, as well as another set in the mixed ecotone with co-located ET Towers. The grassland Small Mammal Exclosure Study is located here, dominantly broom snakeweed (Gutierrezia sarothrae), Mormon tea (Ephedra torreyana), winterfat (Krascheninnikovia lanata), tree cholla (Opuntia imbricata), club cholla (O. clavata)

الوقت: Site Location: Five Points is the general area which emcompasses the Black Grama Grassland (known as Five Points Grassland) and Creosote Core (Five Points Larrea) study sites and the transition between Chihuahuan Desert Scrub and Desert Grassland habitats. Both core sites are subject to intensive research activities, including measurements of NPP, phenology, pollinator diversity, and ground dwelling arthropod and rodent populations. There are drought rain-out shelters in both the Grassland and Creosote sites, as well as another set in the mixed ecotone with co-located ET Towers. The grassland Small Mammal Exclosure Study is located here, as well as many plots related to patch mapping and biotic transitions. Vegetation: Desert Grassland habitat is ecotonal in nature and the Black Grama Core site is no exception, bordering Chihuahuan Desert Scrub at its southern boundary and Plains-Mesa Grassland at its northern, more mesic boundary.
