Functional diversity influence in forest wood stock: a study of the brazilian savanna

Abstract

ABSTRACT:Research regarding biodiversity and ecosystem services has been demonstrating a positive correlation among the ecosystem processes, such as the carbon sink into plant biomass and the quantity of carbon in natural vegetation. Nonetheless, it is hard to understand the biodiversity measurements, because they involve gene, phenotypic, population, species, community and ecosystem diversity. The functional diversity refers to the species richness and variety, their characteristics and how that affects the functioning of an ecosystem. Primary productivity is a key factor that affects the functioning of a forest ecosystem. Thus, the aim of this paper was to evaluate the influence of functional diversity on the woody volume productivity (as a proxy for primary production) in the Brazilian savanna. We used six functional characteristics, and to verify the relation between forest production and functional diversity facets, we tested many models. Regarding wood volume, the best models were the exponential and logarithmic. None of the linear models showed significant regression parameters as there was no additive relationship among the multifaceted aspects of functional diversity and wood volume. We found a positive correlation between the functional diversity and primary productivity, which can be used to forecast the effects of diversity variation on ecosystem services.

“…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.…”
