Woody vegetation dynamics in a floodplain campo de murundus in central Brazil

Abstract

Campos de murundus (grasslands dotted with knolls that are covered with savanna-like woody vegetation) are a common landscape in central Brazil. In this study, we assessed for the first time the dynamics of the vegetation in a floodplain campo de murundus, describing changes in composition and structure of the woody vegetation. ). Nevertheless, the community showed a gain in basal area owing to the growth of surviving individuals and, particularly, to the rise in the number of basal sprouts. We argue that the small floristic turnover may be related to the great resilience of the woody vegetation, whereas the structural changes might reflect the effects of the burnings in the area.

Recurrent wildfires drive rapid taxonomic homogenization of seasonally flooded Neotropical forests

“…With longer dry seasons and increased fire frequencies as a result of climate change (Aragão et al 2008;Marengo et al 2011;Gatti et al 2014), seasonally flooding forests in southern Amazonia will likely suffer significant changes in their species compositions and ecosystem functioning with BH. The diversity of vegetation types in ASP demands a careful fire management plan if one aims to maintain the vegetation diversity in the area, since it is composed of a mosaic of vegetation with very different tolerance to fire, including fire thrivers and fire-tolerant and fire-intolerant vegetation communities (Pinard et al 1999;Marimon et al 2008Marimon et al , 2012Marimon et al , 2015Oliveras et al 2014;Pinto et al 2014).…”

Diversidade de Asteraceae em um campo de murundus no sudoeste de Goiás, Brasil

“…com/s/59e753cd680cfc39f3ed>). Portanto, essa parece ser mais uma característica importante de campos de murundus e que pode indicar que esta fitofisionomia savânica comporta elevada riqueza de espécies (Resende et al 2004;Marimon et al 2012;Pinto et al 2014).…”

“…A fitofisionomia campo de murundus apresenta expressiva riqueza florística, porém, apenas parcialmente conhecida. O componente arbustivo-arbóreo foi mais estudado (e.g., Oliveira-Filho & Martins 1991;Oliveira-Filho 1992b;Marimon & Lima 2001;Resende et al 2004;Marimon et al 2012;Pinto et al 2014) do que o herbáceo-subarbustivo, para o qual destaca-se o estudo de Marimon et al (2012).…”

Man-made soil drainage alters the vegetation structure and woody species distribution in campo de murundus

“…Campos de murundus are characterized as savanna formations which occur in the Brazilian Central Plateau. These fields are important for the maintenance of the water flow, showing groundwater outcrops, especially during the rainy season (Resende, Araújo, Oliveira, Oliveira, & Ávila Júnior, 2004;Pinto, Mews, Jancoski, Marimon, & Bomfim, 2014;Marimon et al, 2015). Also known as parque de cerrado (sensu Ribeiro & Walter, 2008), varjão or covoais, the latter being the term popularly known in southwestern Goiás.…”

“…In recent years the disturbance of agriculture on edaphic and microbiological properties were assessed in the studied area (Santos, Custódio Filho, Freitas, Correchel, & Carneiro, 2014;Gomes Filho et al, 2014;Assis et al, 2014;Carneiro et al, 2015;Rotta et al, 2015;Souza et al, 2016). However, little is known about the anthropogenic effects on the campos de murundus woody flora (Pinto et al, 2014). To our knowledge, no other study has investigated the flora composition and vegetation structure of campos de murundus in Goiás, especially when the surrounding matrix is dominated by monocultures and the land is intensively managed.…”
