Appendages of alto Paraná river basin, making used index based in fishes developed by Fialho (2009). For that then it was considered 14 describes: Globals ( Diversity simpson s rate e equitability), taxonomic (abundance and rich resourse of the species of those families Callichthyidae, Genere Incertae Sedis in Characidae (GISC), Curimatidae and Gymnotidae and trofic group of detritivory and abundance of Sternopygidae family and the rich specie of the Heptapteridae family. In this work the sampling was maden on the dry weater (from may to September of 2009). In 27 sampling sites 14 afluents streams of river Piracanjuba, 7 afluentes of river Meia Ponte and 6 of stream Santa Maria the collect icthyofauna it was maden by the electrofishing method. Witch in on single passing in on part of 100 m located amount and others low waters. The results show that 27 stream reaches only the sampling sites P03, P11, and P21 had a bigger escores value but it was not considered as preserved as IBP protocol prosposed by Fialho (2009). For other wise 10 sampling sites (P01,P07,P08,P09,P12,P16,P18,P19,P22 and P25) showed values igual 0, then it is considered with higher degree of anthropogenic desarrengement. With tthis comes with the conclusion all the sampling site are anthropogenic that can be explained by the intense cattle raising activity in that place. / Este trabalho tem como objetivo, avaliar a qualidade do meio aquático das bacias hidrográficas dos rios Piracanjuba, Meia Ponte e ribeirão Santa Maria, pertencentes à bacia do alto rio Paraná, utilizando um índice baseado em peixes, desenvolvido por Fialho (2009). Para isso, foram considerados 14 descritores, assim distribuídos: globais (Índice de diversidade de Simpson, Equitabilidade), taxonômicos (abundâncias e riqueza de espécies das famílias Callichthyidae, Genere Incertae Sedis in Characidae (GISC), Curimatidae e Gymnotidae e do grupo trófico dos detritívoros; abundância da família Sternopygidae e a riqueza de espécies da família Heptapteridae). Neste trabalho, as coletas foram realizadas no período de estiagem (maio a setembro de 2009), em 27 pontos amostrais, sendo 14 riachos afluentes do rio Piracanjuba, sete afluentes do rio Meia Ponte e seis do ribeirão Santa Maria. A coleta da ictiofauna foi realizada pelo método da pesca elétrica com uma única passada em um trecho de 100 m, localizados a montante e outro na jusante. Os resultados mostraram que dos 27 pontos amostrais, apenas os pontos P03, P11 e P21 tiveram maiores valores dos escores, mas não foram classificados como preservados, conforme protocolo do IBP, proposto por Fialho (2009). Por outro lado, dez pontos (P01, P07, P08, P09, P12, P16, P18, P19, P22, P25) apresentaram valores iguais a zero, sendo assim considerados com maior grau de perturbação antrópica. Com isso, conclui-se que todos os pontos amostrais são antropizados, o que pode ser explicado pela intensa atividade agropecuária da região.

Rates of carbon and peat accumulation were studied in a series of peat landforms within discontinuously frozen peatlands near Fort Simpson, Northwest Territories. An extended distribution of the White River volcanic ash layer was used as a chronostratigraphic horizon to ensure a consistent time span of peat deposition among peat cores and to allow a large core sample size without the expense of radiocarbon dating. Apparent recent carbon accumulation rates measured over the past 1200 years were not significantly different among rich fen, peat plateau, and collapse fen (means 13--14 g C M-2 yr-1). Poor fen and bog mean accumulation rates were 20--22 g C M-2 yr -1 and were not significantly different from each other. Microtopography and water table position appear to be important controls on both carbon and vertical peat accumulation rates. A regional survey incorporating measurements from other parts of the southwestern Northwest Territories and the southeastern Yukon shows rates similar to those near Fort Simpson. / The aggradation of permafrost results in 50 and 65% decreases in carbon and vertical peat accumulation rates, respectively. Carbon and peat accumulation continue to decrease significantly with both increasing permafrost maturity and the number of ground fires. The internal degradation of permafrost results in nearly a doubling in carbon accumulation rates, yet permafrost degradation at the margins of a peat plateau results in carbon accumulation rates similar to the peat plateau. / Clymo's (1984) carbon accumulation model was applied to cores from each landform in addition to a core spanning the entire developmental history of the peatland. Results indicate that true carbon accumulation and sequestration efficiency rates in ombrotrophic peatlands are lower in the upper Mackenzie Valley than for other boreal regions, primarily owing to high decomposition rates. The cessation of carbon accumulation is being approached. The model also serves to highlight the dangers of using apparent and true carbon accumulation rates interchangably. / Apparent and true carbon accumulation rates are significantly lower than published rates from other parts of northern Canada, Finland, and the Former Soviet Union. Low and variable summer precipitation in the region may be a significant factor through increased aerobic decomposition and/or decreased plant production caused by moisture stress.

The purpose of this study was to analyze and evaluate the narrative strategies within the family unit in Harriette Arnow's novel, The Dollmaker. The analysis of the narrative strategies reflected in family stories offered insight into how family members are "identified" or bonded to the family unit. A critical construct was proposed using Kenneth Burke's theories of substance, identification and consubstantiality for the analysis of family narratives as a means of familial identification.Four narrative themes were isolated which typified the storytelling activity in the family.The analysis revealed patterns of language, images and related rhetorical dimensions which affected the process and degree of familial identification. The analytical tool developed for this study was demonstrated to be of considerable utility when applied to a literary artifact. Further refinement of this tool would result in a more workable instrument for analyzing the storytelling activity which permeates the family unit.

A static chamber technique was used to measure methane emissions in July and August, 1995 from peatland sites in the Fort Simpson area, Northwest Territories, at the southern fringe of the discontinuous permafrost zone. Sites were classified ecologically and geomorphologically, and water table and temperature regimes were monitored. / Methane emissions ranged from $-$3.3 to 1144.2 mg/m$ sp2 cdot$d, from raised frozen sites to pond sites, respectively, similar to emissions recorded from other boreal regions. Water table was the strongest predictor of CH$ sb4$ emission. Although peat temperature is significantly correlated to methane flux, it did not significantly improve the flux-water table relationship. Methane storage within the saturated portion of the peat profile ranged from 0.2 to 4.2 g/m$ sp2$ over depths ranging from 30 to 76 cm, and did not play a large role in surficial emissions. The zone immediately above and below the water table appears to regulate methane diffusion to the surface. Residence times (storage/flux) ranged from 12 to 30 days in poor fens, and from 6 to 5789 days in fens. / Ranges and mean fluxes of methane were determined according to landform and water table position. Based on the geomorphology of the area, overall flux determined for the Fort Simpson area, map NTS 95H, NW1/4, is estimated to be 19 mg/m$ sp2 cdot$d.
