The effect of hydroperiod on seed banks in semi-permanent prairie wetlands
… was to determine if hydroperiod affected seed pool characteristics. Additionally, 48 samples were collected in 1986 from wetland P1 to determine if seed bank composition changed annually without a change in mature vegetation. Seed bank composition was determined by placing soil samples in …

Breeding System, Heterozygosity, and Seed Germination in a Population of Missouri Bladder-Pod, Lesquerella Filiformis Rollins
… species, allozyme genotypes for seeds produced from one generation of natural breeding were used to estimate the breeding system and to examine the fitness consequences of heterozygosity. Both multilocus and single-locus estimates of the outcrossing rate (tm=1.000, ts=0.996) …

The soil seed bank in Agathis australis (D. Don) Lindl. (kauri) forests of northern New Zealand and its potential role in secondary successions
The soil seed bank in Agathis australis (D. Don) Lindl. (kauri) forests of northern New Zealand is quantified, and its potential role in secondary successions examined. Seed bank data from a number of kauri forest sites stratified by successional time and distance from forest edges are summarized …

Investigating mechanisms maintaining plant species diversity in fire prone Mediterranean-type vegetation using spatially-explicit simulation models
… this study: regeneration mode, annual maximum seed production, seed size, maximum crown diameter, drought tolerance, dispersal mode and seed bank type. Trait sets are used for the definition of plant functional types (PFTs). The PFT dynamics are simulated annual by iterating life history …
