How to live in contrasting habitats? Acquisitive and conservative strategies emerge at inter- and intraspecific levels in savanna and forest woody plants

Short gradient, but distinct plant strategies: The CSR scheme applied to subtropical forests

“…Restinga ecosystems (Silva, Souza, Caliman, Voigt, & Lichston, 2018) and in ecotones between savanna and forest ecosystems (Dayrell et al, 2018;Maracahipes et al, 2018). Components C and S performed better in differentiating regional forest types, whereas component R showed not only less importance (as can be expected, to some extent, for tree species and tree communities in general: Pierce et al, 2013), but also less differences between forest types.…”

“…The stress‐tolerant component was very important for the subtropical forests studied here, especially for Araucaria and Pampean forests, which face lower minimum temperatures and/or larger ranges of annual temperature. Other studies have shown the relation of this component to colder environments (Vasseur et al., 2018) or, in more general terms, to harsher environments such as in coastal Restinga ecosystems (Silva, Souza, Caliman, Voigt, & Lichston, 2018) and in ecotones between savanna and forest ecosystems (Dayrell et al., 2018; Maracahipes et al., 2018). Components C and S performed better in differentiating regional forest types, whereas component R showed not only less importance (as can be expected, to some extent, for tree species and tree communities in general: Pierce et al., 2013), but also less differences between forest types.…”

“…Over larger spatial scales, latitude has a direct effect on species distribution (Gaston, 2000), and, as a result of the adaptation of species or even populations to climate, also influences the distribution of ecological strategies (Vasseur et al., 2018). Environmental filters determine species distributions via selection on species characteristics, resulting in changes in species composition (Bergamin et al., 2012; Rezende et al., 2015), alpha and beta diversity (dos Santos, Saraiva, Müller, & Overbeck, 2015), and ecological strategies (Maracahipes et al., 2018) of communities across environmental gradients. Thus, in transition zones between phytogeographical units, even short variations in environmental conditions may determine different ecological strategies at the regional scale, as observed by the significant associations of components C, S, and R with temperature and precipitation variables.…”

Potencial de plantios homogêneos de espécies nativas para catalisar a recuperação da biodiversidade e proporcionar o uso sustentável da Reserva Legal

“…Experimentos controlados de biodiversidade e funcionamento de ecossistemas (BEFbiodiversity and ecosystem functioning) têm apontado que, em média, sistemas com mais espécies possuem maior biomassa acumulada e recursos utilizados dentro dos níveis tróficos, sendo que a variância destes atributos é menor ao longo do tempo, quando comparados a sistemas com somente uma espécie(BALVANERA et al 2006;CARDINALE et al 2006;DUFFY 2009). Assim, espécies em ambientes florestais ricos em nutrientes podem investir em larga superfície foliar por unidade de massa foliar, que aumenta a taxa de crescimento da planta e otimiza sua habilidade competitiva por luz no interior das florestas(MARACAHIPES et al 2018). Em geral, espécies tolerantes à sombra possuem área foliar específica e massa da semente maiores(WESTOBY et al 2002).…”
