Abstract
Community structure and functional diversity of polypores (Basidiomycota) in the Atlantic Forest of Santa Catarina State, Brazil
Highlights
Polypores constitute one of the main groups of wood-decay fungi
The following substrate data were recorded for each fungal occurrence: diameter and length, and the condition [living trunk (LT); dead trunk (DT): standing or fallen logs and stumps; living branch (LB); dead branch (DB); and on the ground (OG)]
Community structure based on species abundance showed (Figure 3; Table 1) that Polyporus dictyopus Mont., Perenniporia martia (Berk.) Ryvarden, and Fuscoporia wahlbergii (Fr.) T
Summary
Polypores constitute one of the main groups of wood-decay fungi. The diversity of wood-decay fungi of the Atlantic Forest has been approached by several authors (e.g., LOGUERCIO-LEITE et al, 2002; RYVARDEN; MEIJER, 2002; DRECHSLER-SANTOS et al, 2008). Baltazar and Gibertoni (2009) presented the most extensive literature list with 733 aphyllophoraceous species, of which more than 50% were polypores. Despite their importance in the ecology of forests, there are few ecological studies about this group in the Atlantic Forest (e.g., COCKLE et al, 2012). Ecological studies have suggested that different groups of polypore species, acting as parasites and/or saprophytes, degrade different types of woody substrates. These functional groups have distinct decay capabilities and perform different roles in ecosystems. Among the wood-decay fungi, Polyporaceae s.l., as well as some Corticiaceae s.l. and Hymenochaetaceae, have been considered well suited to study the key role of woody debris in old-growth forests (BADER et al, 1995)
