Florística e fitossociologia em três diferentes fitofisionomias campestres no Sul do Brasil

Abstract

-(Floristic and phytosociology of three different grassland physiognomies of Southern Brazil). The purpose of this study was to evaluate the composition and structure of three different types of grassland vegetation of Southern Brazil. We aimed to discuss the floristic similarities among these areas and the influence of the Cerrado flora in their composition. Thirty plots of 1 × 1 m were placed in each area for the quantitative sampling. Additionally, species that occurred around the plots were also collected. In total, 283 species were sampled, with 163 species in CS, 87 species in CU, and 59 in CR. 36.48% (85) of the species sampled in this study also occur in the Cerrado. The cluster analysis showed that the floristic composition of the three grassland areas is significantly different due to several factors, especially the soil water system. Keywords: Campos Gerais, community structure, grassland, Paraná State, Southern Brazil Das espécies identificadas em nível específico,36,48% (85) foram citadas para áreas de Cerrado da região. As análises de agrupamento apontaram que as composições florísticas das três formações campestres são significativamente distintas entre si, isto se deve a diversos fatores, especialmente em relação ao regime hídrico do solo.

Classification of South Brazilian grasslands: Implications for conservation

“…In recent years, there have been advances in the floristic knowledge of grassland ecosystems in the region, but studies usually considered single sites or, at best, smaller regions, and have been conducted using different sampling designs and methods (e.g., for Pampa: Caporal & Boldrini, ; Ferreira & Setubal, ; Freitas, Boldrini, Müller, & Verdum, ; Setubal & Boldrini, ; Pinto et al., ; Menezes, Müller, & Overbeck, ; Silva Filho, Macedo, Souza Vieira, & Neves, ; for highland grasslands: Zanin, Longhi‐Wagner, Souza, & Rieper, ; Moro & Carmo, ; Kozera, Kuniyoshi, Galvão, & Curcio, ; Andrade et al., ; Moraes et al., ; Silva, Andrade, Velazco, Galvao, & Carmo, ). These studies are important for describing local floristic patterns and grassland vegetation structure and can be used to describe regional vegetation patterns.…”

Floristic survey of the Furnas Gêmeas region, Campos Gerais National Park, Paraná state, southern Brazil

“…Several studies have pointed these families as having the larger number of taxa in the Campos Gerais region (Hatschbach and Moreira Filho 1972, Carmo 2006, Nanuncio and Moro 2008, Dalazoana and Moro 2011, Moro et al 2012, Silva et al 2016, and therefore, we noticed that FG still retains part of its original flora.…”

Synopsis of Poaceae in the grassland formations of the Parque Estadual do Guartelá, Paraná State, Brazil

“…Quite a few of the floristic surveys conducted in Campos Gerais, mention the Poaceae taxa. Among them, it is worthwhile to highlight the works presented by Aguiar & Vieira (2011) performed in the Parque Estadual do Cerrado; Ferreira & Maranho (2011), Oliveira & Maranho (2011), Freitas et al (2011), and Silva et al (2016) in the Parque Estadual Vila Velha, and, finally, IAP (2002) and Carmo (2006) in the PEG, where 40 taxa were indicated, of which seven were identified to genera level and one to family.…”
