Abstract

Functional traits and strategies of trees can effectively indicate the progress of forest recovery during succession. This study investigates variations in leaf and wood traits, CSR functional strategies, and trade-offs in resource acquisition adopted by plants in secondary forests of different recovery ages, comparing them to old-growth forests. We also examined the relationships between traits, aboveground biomass dynamics, and edaphic variables in the Bragantina region, Eastern Amazon. Our evaluation focused on leaf area (LA), specific leaf area (SLA), leaf dry matter content (LDMC), and wood density (WD). Secondary forests exhibited higher LDMC and WD compared to old-growth forests, with low trait variation among secondary forests regardless of recovery age. Stress tolerance (S) was the dominant strategy in secondary forests, whereas old-growth forests showed a balanced proportion of stress tolerance and competitive strategies. Coordination was identified among WD, stress strategy (S), and LDMC. Significant relationships were found between functional traits and soil variables. Our results highlight the slow functional recovery of secondary forests in the Bragantina region which is associated with intense land use prior to natural regeneration and the fragmented landscape.

期刊介绍: FLORA publishes original contributions and review articles on plant structure (morphology and anatomy), plant distribution (incl. phylogeography) and plant functional ecology (ecophysiology, population ecology and population genetics, organismic interactions, community ecology, ecosystem ecology). Manuscripts (both original and review articles) on a single topic can be compiled in Special Issues, for which suggestions are welcome. FLORA, the scientific botanical journal with the longest uninterrupted publication sequence (since 1818), considers manuscripts in the above areas which appeal a broad scientific and international readership. Manuscripts focused on floristics and vegetation science will only be considered if they exceed the pure descriptive approach and have relevance for interpreting plant morphology, distribution or ecology. Manuscripts whose content is restricted to purely systematic and nomenclature matters, to geobotanical aspects of only local interest, to pure applications in agri-, horti- or silviculture and pharmacology, and experimental studies dealing exclusively with investigations at the cellular and subcellular level will not be accepted. Manuscripts dealing with comparative and evolutionary aspects of morphology, anatomy and development are welcome.
