Enrichment plantings into secondary forest are an important option in restoring species diversity and ecosystem services. However, little attention has been given to environmental requirements for species performance. This study evaluated the effects of lightgaps and topographic position on the growth and survival of four native tree species (Pouteria caimito, Garcinia macrophylla, Dipteryx odorata and Cynometra bauhiniaefolia) planted into a 26-year old secondary forest originating from abandoned pastures in the central Amazon Basin. Artificial lightgaps and control plots under closed canopy were uniformly distributed on plateaus and bottomlands near water bodies. Seedlings were planted randomly into the plots and monitored …

Floodplain forest species diversity is driven, in part, by variation in disturbance regime. Flood patterns create heterogeneity in microsite quality from small differences in elevation across a floodplain which, in turn, influence flood timing and duration. Differences in species’ regeneration niches in relation to hydrologic patterns can account for long-term coexistence of various species. In the past century floodplain forests have exhibited a wide range of changes in stand development and species composition as a result of altered hydrology in rivers and floodplains. I evaluated the role of regeneration in floodplain forest systems of the Lower Mississippi River Alluvial Valley …

LSU Master's Theses
Ecological processes controlling transition areas of coastal wetlands between marshes (not forested) and swamps (forested) are poorly understood, despite important ecosystem services provided and strong interest in managing for ecosystem structure and function. The objective of this work was to identify how soil chemistry and stand density control individual-tree growth of the important coastal species baldcypress (Taxodium distichum (L.) Rich.) and pondcypress (Taxodium distichum var. imbricarium (Nutt.) Croom) along a coastal salinity gradient. Tree cores, soil samples, and stand density measurements were collected for sixty cypress trees at the coastal Joyce Wildlife Management Area, Louisiana, which is a …
