Resumo: | In order to detect patterns of rural vegetation in the coastal region of the Pampa Biome, a floristic survey of a natural pasture located on the Southern Coastal Plain in Rio Grande do Sul, in the buffer zone of the Ecological Reserve of Taim (32 ° 32'03.27 S” and 52 ° 31'43.98 ”O), was conducted. The evaluations were carried out by in frames 0,25m² to estimate the botanical composition and the Daubenmeire scale was used to assess plants coverage. Aiming to detect possible patterns of vegetation variation in a Entisols Quartzipsamments, sandy texture, flat relief, lake and marine sediment substrate, the sample units were distributed in order to characterize three visually contrasting conditions: I - higher relief, with greater drainage and high proportion of bare soil (> 30%); II - intermediate relief, medium drainage and medium proportion of uncovered soil (10 to 20%); III.- lower relief, higher humidity and lower proportion of uncovered soil (<10%). 66 0.25m² frames were used, distributed in the three conditions. A total of 18 species were recorded in six families. The specie with the greatest coverage was Axonopus parodii regardless of soil condition, since Paspalum pumilum was only found in condition III, indicating its high dependence on greater water availability. All species in the hot season are perennial while all hibernal species are annual, and of these, Poa annua shows a strong tendency to greater coverage with increased soil moisture. |

Las evaluaciones se realizaron en tablas de 0,25m² para estimar la composición botánica y se utilizó la escala de Daubenmeire para evaluar la cobertura. Con el fin de detectar posibles patrones de variación de la vegetación en un Neossolo cuarzo hisromórfico, textura arenosa, relieve plano, sustrato lacustre y sedimentario marino, se distribuyeron las unidades de muestra para caracterizar tres condiciones visualmente contrastantes: I - relieve mayor, con mayor drenaje y alta proporción de suelo desnudo (>30%); II - relieve intermedio, drenaje medio y proporción media de suelo descubierto (10 a 20%); III.- Menor relieve, mayor humedad y menor proporción de suelo descubierto (<10%). Se utilizaron 66 marcos de 0,25m² distribuidos en las condiciones. Se registró un total de 18 especies en seis familias. La especie con mayor cobertura fue Axonopus parodii independientemente de la condición del suelo, mientras que Paspalum pumilum solo se encontró en la condición III, lo que indica su alta dependencia de una mayor disponibilidad de agua. Todas las especies en la estación cálida son perennes mientras que todas las especies hibernales son anuales, y de estas, Poa annua muestra una fuerte tendencia a una mayor cobertura con mayor humedad del suelo.Com o objetivo de detectar padrões de vegetação campestre da região litorânea do Bioma Pampa foi conduzido levantamento florístico de uma pastagem natural localizada na Planície Costeira Sul no Rio Grande do Sul, na zona de amortecimento da Reserva Ecológica do Taim (32°32’03.27”S e 52°31’43.98”O). As avaliações foram realizadas em quadros de 0,25m² para estimar a composição botânica e utilizou-se a escala Daubenmeire para avaliação de cobertura. Visando detectar possíveis padrões de variação de vegetação num Neossolo Quartzarênico hidromórfico hístico, textura arenosa, relevo plano, substrato sedimentos lacustres e marinhos, as unidades amostrais foram distribuídas de modo a caracterizar três condições visualmente contrastantes: I – relevo mais alto, com maior drenagem e alta proporção de solo descoberto (>30%); II – relevo intermediário, drenagem média e média proporção de solo descoberto (10 a 20%); III.- relevo mais baixo, maior umidade e menor proporção de solo descoberto (<10%). Foram utilizados 66 quadros de 0,25m² distribuídos nas três condições. Foi registrado um total de 18 espécies em seis famílias. A espécie de maior cobertura foi Axonopus parodii independentemente da condição do solo, já o Paspalum pumilum somente foi encontrado na condição III, indicando sua alta dependência de maior disponibilidade hídrica. Todas as espécies de estação quente são perenes enquanto todas hibernais são anuais e destas, Poa annua mostra forte tendência a maior cobertura com o aumento da umidade do solo.Research, Society and Development2020-12-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1098510.33448/rsd-v9i12.10985Research, Society and Development; Vol. 9 No. 12; e24791210985Research, Society and Development; Vol. 9 Núm. 12; e24791210985Research, Society and Development; v. 9 n. 12; e247912109852525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/10985/9879Copyright (c) 2020 Gabriela Maia de Azevedo; Juares Gonçalves da Silva Junior; Otoniel Geter Lauz Ferreira; Lisandre de Oliveira; Carlos Nabinger; Élen Nunes Garcia; Stefani Macarihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAzevedo, Gabriela Maia de Silva Junior, Juares Gonçalves daFerreira, Otoniel Geter LauzOliveira, Lisandre deNabinger, CarlosGarcia, Élen NunesMacari, Stefani2020-12-30T23:32:22Zoai:ojs.pkp.sfu.ca:article/10985Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:55.662210Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
