Interactions Between the Herbaceous and Shrubby-Arboreal Components in a Semiarid Region in the Northeast of Brazil: Competition or Facilitation?

Abstract: -Under conditions of high stress, interactions between species can be positive. Islands of perennial vegetation can improve the conditions of the understory and facilitate the establishment of herbaceous plants. The hypothesis of this study is that islands of perennial vegetation in an area of caatinga harbor, a greater richness, diversity and density of herbaceous plants, and that individuals reach a greater height and diameter than in open spaces. The study was conducted in Petrolândia, Pernambuco, Brazil. T… Show more

“…Em ambientes antropizados, existe uma maior disponibilidade de luz, modificando a estrutura do estrato herbáceo (Santos et al 2006, Benevides et al 2007, Silva 2011, Zelarayán et al 2015. Apesar de evidências mostrarem que o desenvolvimento deste estrato é limitado pelo sombreamento (Inácio & Jarenkow 2008, Lima & Gandolfi 2009, Citadini-Zanetti et al 2011, ilhas de vegetação perene podem facilitar o estabelecimento de plantas herbáceas na Caatinga (Silva et al 2015).…”

“…Commonly, some of these areas are abandoned after land use and the vegetation naturally regenerates. Consequently, landscapes of caatinga vegetation are often composed of young and mature forest fragments (Araújo et al 2007;Lopes et al 2012;Silva et al 2015;Santos et al 2016;Araujo et al 2017). Therefore, the caatinga becomes a good model for monitoring the effect of forest conservation status and precipitation temporal variation on leaf morphofunctional attributes of populations.…”
