Ferns, Fern Gametophytes, Fern Reproduction, Woodman Hollow in Iowa
Field observations of spore availability, gametophyte establishment and survival, and sporophyte production were made over a one-year period. Maximum spore release for most species occurred shortly after spore maturation in mid to late summer, but some spores remained on sporophyte fronds through the winter and were available for germination the following spring. Gametophytes of Cystopteris fragilis, Woodsia obtusa and Adiantum pedatum became established in late summer and fall. Production of sporophytes occurred both in fall and in the following spring. Both gametophytes and juvenile sporophytes survived the winter in relatively unchanged condition. Results indicate that it is feasible and important to correlate field studies with current laboratory studies of fern reproductive biology.
