Physiological and Morphological Responses of Nitrogen-Fixing Red Alder (Alnus Rubra) and Sitka Alder (Alnus Viridis Ssp. Sinuata) to Flooding: Inter- and Intraspecific Comparisons
… soils. To identify factors that contribute to flood tolerance in these two species and to determine whether red alder progeny from naturally wet and dry sites vary genetically in their capacity to tolerate flooding, I conducted greenhouse experiments subjecting both species to a short term …

The Regeneration Niche in Bottomland Hardwood Forests: Tree and Herbaceous Communities Along Interacting Gradients of Flood and Light in East Texas Floodplains
… on how gradients in light availability and flooding shape understory composition and exploring a potential trade-off between shade and flood tolerance. Field surveys demonstrated that small canopy gaps in BLH forest support shade-tolerant tree seedlings and increase understory plant …

The effects of rhizosphere inundation on the growth and physiology of red maple (Acer rubrum L.) seedlings derived from wet and dry sites
… three physiographic regions of Virginia were flooded to test whether red maple seedlings derived from wet sites are affected differently by flooding than are seedlings derived from dry sites. Thirteen weeks of soil inundation on seedling growth found no interactions between flooding and …

Factors affecting root system response to nutrient heterogeneity in forested wetland ecosystems
… did not respond to P-rich patches in both floodplain (nutrient-rich) and depressional swamps (nutrient-poor) swamps, but results were inconclusive because the growth medium (sand) potentially hindered root growth. In floodplain forests, roots proliferated into N-rich patches but not P-rich …

Sapling growth and recruitment as affected by flooding and canopy gap formation in a river floodplain forest in southeast Texas
… determine regeneration patterns. I reconstructed flooding history using a combination of river gauging, a local water-level recorder, and contour maps. 1979 was an extreme flood year for this site, as was 1989. Reduction in flooding frequency since dam construction in 1965 was significant for all …

Threshold for complete submergence of Typha domingensis.
… data in a constructed wetland after a natural flood, followed by two controlled experiments designed to simulate deep flood conditions. In the observational study, rhizomes from 750 Typha ramets were methodically unearthed to reveal that none of the individual plants survived a multi-week …

Screening Diverse Soybean Germplasm for Water-logging Tolerance
… soybean germplasm collection for water-logging tolerance (WLT) at both the V5 and R1 growth stage and to develop a method to screen soybean for WLT in greenhouse. One hundred thirty five genotypes consisting of historical genotypes, PIs, drought and WLT tolerant breeding lines were screened for …
