Floristic, frequency, and vegetation life-form spectra of a cerrado site

Abstract: We used Raunkiaer's system to classify in life-forms the vascular plants present in 12 random 25 m 2 quadrats of a cerrado site. The study area is covered by cerrado sensu stricto and is located in the Valério fragment, at about 22º13'S and 47º51'W, 760 m above sea level, in the Itirapina Ecological and Experimental Station, São Paulo State, southeastern Brazil. The floristic spectrum considers the life-form of each species, while in the frequency spectrum, each species is weighted by its frequency. The vegeta… Show more

“…O cálculo do volume com casca obtido pela cubagem rigorosa forneceu um total de 16,18 m³/ha de madeira, correspondendo a 10,84 m³/ha (67%) o volume total dos fustes e a 5,33 m³/ha (33%) o dos galhos. Batalha et al (2004) Figura 1. Curva de forma exponencial negativa da distribuição diamétrica de 490 árvores encontradas em um hectare de cerrado stricto sensu, na região de Planaltina de Goiás.…”

“…A revisão bibliográfica encontrou poucas referências (SCOLFORO; SILVA, 1993;PAULA et al, 1998;OLIVEIRA et al, 1998;PAULA, 2003;BATALHA et al, 2004;REZENDE et al, 2006) relativas ao volume de madeira da fitofisionomia cerrado. Deduz-se, consequentemente, que o parâmetro volumétrico de madeira para as áreas de cerrado é pouco conhecido, mesmo reconhecendo a existência, em várias regiões com vegetação nativa, de uma intensiva extração madeireira para fins energéticos.…”

“…Thus, for these reasons the frequency spectrum is not suggested in studies of rocky outcrop sites. Similarly to that described by Batalha & Martins (2004) for cerrado sites, the floristic spectrum is suggested, if working in sufficiently large areas because it could provide an indication of the prevailing phytoclimate. On the other hand, the vegetational spectrum is recommended for small-area analysis, because it provides a detailed description of the physiognomy related with ecological factors.…”

“…For instance, most tropical ecosystems (Batalha and Martins, 2004;Koulibaly et al, 2006;Ouedraogo et al, 2011;Schmidt et al, 2005) have ascertained that the phanerophytes are the most dominant life form especially in the forested regions. In most savannas ecosystems however, the therophytes (Aghaei et al, 2013;Medvecka et al, 2013;Turki and El Shayeb, 2005), chamaephytes (Gimenez et al, 2004) and hemicryptophytes (Amjad, 2012;Dimopoulos and Georgiadis, 1992;Klimes, 2003) have been reported to dominate different regions depending on how well they interact with their environment (Zarezade et al, 2007).…”
