Abstract
Lichens are organisms capable of interacting with the environment, playing an important role in the modification of their substrate. In coastal areas of northeastern Brazil with sandy soils, as an extension of Atlantic rainforest, or in an interface with semi-arid Caatinga biome and high mountain humid forests, named brejos , lichens of the family Cladoniaceae are found forming pillows on these soils. They interact with their substrate, influencing the chemical composition and biota. In this study, we summarize data about the interaction of these lichens with Quartzarenic Neosols, which occurs in this phytophysiognomy named tabuleiros or cerrados .
Highlights
Lichens are exceptional organisms in their interactions with environmental factors and play an important role in ecosystem functioning (Nash III, 2008).In this context, in natural environments, lichens can be found inhabiting different tree branches (Figure 1), barks (Figure 2), leaves (Figure 3), rocks (Figure 4), and soils (Figure 5), in addition to other, man-made substrates

Researchers are focusing on the role of secondary metabolites of lichens in ecosystem functioning, since they can act in rock weathering (Silva et al, 2012) and soil development through the percolation of phenolic compounds which result from their secondary metabolism, interfering in the ecosystems’ biota and chemical composition
