Tree species dominance in neotropical savanna aboveground biomass and productivity

Above-ground biomass accumulation in Cerradão managed by the mass ratio

“…Forests, such as the Cerradão vegetation, are closed canopy environments where light resources are limited; thus, higher growth potential and lower growth investment strategies determine species survival and growth (Finegan et al 2015;Hoffmann et al 2012;Poorter & Rozendaal 2008;Wright et al 2010). In addition, positive relationships between potential growth traits, especially maximum height, and aboveground biomass corroborate studies that have evaluated the ability of community-weighted means to estimate ecosystem properties and processes (Ali et al 2017;Finegan et al 2015;Terra et al 2021;Vargas-Larreta et al 2021).…”

“…Although wood density improves estimates of woody species biomass and represents a trade-off between growth and survival (Chave et al 2006;Pérez-Harguindeguy et al 2016;Souza, 2020), no significant relationships were found between community-weighted means of wood density and above-ground biomass in the assemblages, unlike the results of Ali et al (2017), de Souza et al (2019), andVargas-Larreta et al (2021), who found significant relationships between communityweighted means of wood density and biomass. The relationship between these variables may have been affected by the present scale of analysis, since the variance of wood density (mean values) occurred at larger spatial scales, following gradients of temperature and precipitation, and edaphic characteristics (Oliveira et al 2022;Terra et al 2018Terra et al , 2021.…”

“…Using biomass accumulation as an example, depending on the environment, species in stands with higher specific leaf area may have a competitive advantage over species with lower specific leaf areas, promoting an increase in the total leaf area of these species assemblages, increasing their photosynthetic potential and consequently their total biomass. A conventional method for examining ecosystem processes using functional traits is by using trait mean, maximum, or variance values, weighted by the number of individuals within a community; a "community weighted mean" (CWM) (Ali et al 2017;Finegan et al 2015;Garnier et al 2004;Lavorel et al 2008;Terra et al 2021).…”

“…The use of CWM traits and functional metrics is becoming increasingly common worldwide (Ali et al 2017;Finegan et al 2015;Sonkoly et al 2019;Vargas-Larreta et al 2021). For the Brazilian savannah (Cerrado biome), studies have been conducted to verify strategic differences between species from contrasting environments (Freitas et al 2012;Hoffmann et al 2005Hoffmann et al , 2012Maracahipes et al 2018), to determine the relationships between ecosystem processes and functional diversity (Meira Junior et al 2016;Terra et al 2018Terra et al , 2021 and to verify functional changes in veetation over time (Meira Junior et al 2016). However, these studies have been primarily conducted only in cerrado sensu stricto and semi-deciduous forests.…”

Species Distribution and Patterns in a Forest-savannah Ecotone: Environmental Change and Conservation Concerns

“…Such dominance is however not characteristic of such transition zone alone, but are also patterns of dominance and monodominance that are similar to rainforest ecosystems [18] . The dominance of species in ecosystem borders directly on the successes species achieves in an environment [19] . Such is mainly characterized by the frequency/abundance of such species in a community.…”
