Summary

Recurring drying and wetting events are likely to increase in frequency and intensity in predicted future droughts in the central United States and alter the regeneration potential of species. We explored the resistance of seed banks to successive droughts in 53 sites across the nine locations in baldcypress swamps in the southeastern United States. Along the Mississippi River Alluvial Valley and northern Gulf of Mexico, we investigated the capacity of seed banks to retain viable seeds after successive periods of drying and wetting in a greenhouse study. Mean differences of species richness and seed density were compared to examine the interactions of successive droughts, geographical location and water regime. The results showed that [...]

Purpose

Data were collected to determine the effect of repeated drying events on seedbank species from the Mississippi River Alluvial Valley and the northern Gulf of Mexico, to inform management and conservation decisions on coping with future drought.
