Changes in plant communities associated with timber management in natural forests in the moist tropics

摘要: Introduction Disturbance is integral to a forest's ecology, and selective logging form of disturbance. Whether disturbance natural or anthropogenic, it likely that the biotic interactions within system are influenced by it. This volume attests importance tropical forest function diversity. And while there still many unknowns in how change with perturbation, particularly when impacts as variable those associated timber management, an understanding these changes important inform development management interventions ecologically sustainable, i.e. where manipulations stay limits patterns for forests (e.g. ecological forestry, sensu Seymour & Hunter 1999) ecosystem functions maintained (Forest Stewardship Council (FSC) 2000). Generally, approaches study other silvicultural based on comparisons, example control versus impact designs unlogged, old-growth used (Johns 1983; Lambert 1992; Silva et al . 1995), various treatments compared, different systems 1996; Pinard Putz 1996), harvest intensities (Kasenene 1987; Panfil Gullison 1998; van der Hout 1999), stand-improvement (Fox Chai 1982; de Graaf 1999; Gerwing 2001). But forms anthropogenic impacts, detecting difficult because complexity variability (temporal spatial) (Underwood 1991, 1993).
