Disparate distribution patterns between canopy and subcanopy life-forms in two temperate North American forests

摘要: Quantitative vegetational data of canopy and woody subcanopy species (two life-forms adapted to occupy different strata at maturity) were compared with collected in two temperate forest ecosystems determine whether they exhibit a similar pattern distribution. Tidal freshwater swamps (21 stands) southern Appalachian forests (19 examined from obtained using identical sampling methods. Separate structural analyses the canopy, sapling, indirect ordination algorithm Detrended Correspondence Analysis. Environmental measurements each stand assessed for their relationship distribution stands depicted by diagrams.
