The fate of areas of south-eastern American deciduous forests which were dominated, before the arrival of the pathogen, by chestnut and species of oak has been traced (Fig. 10) over nearly 40 years (Day Monk, 1974). The demise of chestnut from its standing as a canopy dominant was rapid, taking about 20 years, with a complete failure to return. During this period eeosystem productivity was reduced (as shown by a reduction in tree basal area. Fig. 10). However, the place of chestnut in the forest has been taken by a number of species, in particular oak and tulip tree, which have steadily increased in dominance. The community has clearly changed markedly but the ecosystem as a whole has shown complete recovery, in terms of re-establishing tree basal area. The place of chestnut in the oak-chestnut forests has been taken by other native species. So in the context of conservation, although the loss of chestnut is unfortunate, it has not been at the eost of an invasion of alien species of tree. 

A general scheme for the bloassay directed Isolation and characterization of antimicrobial agents from plants Is presented and discussed. The utility of the procedure Is demonstrated by the characterization of two antimicrobial alkaloids from the tulip tree, Llrlodendron tullplfera L. The generalization of the approach to the study of allelopathic agents In plants Is suggested. 

We wish to emphasize that our success for characterization of the substances responsible for the antimicrobial activity found in the tulip tree was due to utilization of a plan of procedure which incorporates the following elements ...

Tulip trees are tall-growing with alternate, 3-lobed leaves. Yellow flowers appear near the top of the tree in late spring or early summer. Tulip tree makes a fine specimen tree for large properties.

Fig. 7.13 Potential foodplants along a 3600-mile latitudinal transect of the ran Papilio glaucus (at the approximate bisection of the ranges of the two races see Fig 7 The most frequently reported foodplant species are numbered (1-20) for identification here and listed in Fig. 7.14. The ranges of paper birch, Betulapapyrifera ( 2), and tulip tree, Liriodendron tuHpifera ( 18) illustrate the closeness of the hostplant transition zone (i.e. where the northern meets the southern) with that for the two P. glaucus races (cf.Fig. 7.12).
