Dung-beetle pollination and more
Sakai and Inoue present the first report on the pollination of Lowiaceae, a family of the Zingiberales, and describe a new system of dung-beetle pollination. Further, Sakai and members of the Canopy Biology Programin Sarawak, originally led by T. Inoue, continue their comprehensive research (AJB 85: 1477-1501) on the pollination biology of the lowland dipterocarp forest of Sarawak, Malaysia, with observations on beetle pollination of Shorea Dipterocarpaceae). (see p. 56 and p. 62)
Forest recruitment
Clark et al. provide an exceptionally deep review of recruitment limitation in forests. Their conclusions about the limitations of short-term/small spatial studies are thought provoking and troubling. (see p. 1)
Single-founder genetics
Trifolium amonenum was believed extinct until a single plant was discovered in 1993. Knapp and Connors compare allozyme diversity in offspring of this single plant vs. that of a population of 200 individuals discovered during the course of the study and find surprising diversity in the bottlenecked population. (see p. 124)
Re-evaluation of Berg's correlation-pleiades concept
Studies to date have generally supported the correlation-pleiades concept proposed by Berg in 1960 that floral traits associated with specialized pollination mechanisms are decoupled from phenotypic variation in vegetative traits. Armbruster et al. tested this idea using nine tropical species and found that the relationship between flower and vegetative traits is not easily predicted.
