The 141‐year period for Dr. Beal's seed viability experiment: A hybrid surprise
American Journal of Botany, Volume 110, Issue 11, November 2023., 2023 Abstract Premise In 1879, Dr. William Beal buried 20 glass bottles filled with seeds and sand at a single site at Michigan State University. The goal of the experiment was to understand seed longevity in the soil, a topic of general importance in ecology, restoration, conservation, and agriculture, by periodically assaying germinability of these seeds ...

Iridoid Glycosides from Verbascum thapsus L.
Chemical and Pharmaceutical Bulletin, 1991 Five novel iridoid glycosides were isolated from the fresh whole plants of Verbascum thapsus L. (Scrophulariaceae). The structures of these iridoid glycosides were determined ont he basis of spectral and chemical evidence. These compounds were classified into two types : one iridoid glycosides contains ajugol, and the others contain 6-O-(α-L ...

Compost legacy effects in active roadside restoration: Medium‐term shifts in plant succession
Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.Roadside restoration experiment established on volcanic tephra following road construction in Andean Patagonia. A single application of municipal (MC) or biosolids (BC) compost rapidly increased plant cover compared with untreated controls (C) but led to distinct, exotic‐dominated plant communities over 6 years.
