SummaryExtensive variation was observed for alkaloids in Lupinus nanus. Of the nine alkaloids studied, one was always present, one was nearly always present, one was nearly always absent, and the occurrence of the remaining six was extremely variable. There was little divergence between four geographic subspecies. All populations exhibited polymorphisms for at least two alkaloids. The average number of polymorphisms per population was approximately 4.5 or 5o percent of alkaloids studied. The highest number was found in L. nanus ssp latifolius and the smallest number in L. nanus ssp apricus. The high frequency of some alkaloids suggests natural selection. Alkaloid number 9 was found in all plants throughout all populations of the four subspecies examined. Methods for measuring divergence of populations from subspecies profiles in terms of alkaloid frequencies were developed. Estimates indicated that marginal populations often diverged more from subspecies profiles than did central populations. Methods for measuring population variance were developed and estimates often indicated that central populations were more variable than marginal populations. But these generalizations were not without exception. POPULATIONS L. nanus ssp apricus: Five populations of L. nanus ssp apricus were studied. Their geographic distribution is concentrated north of San Francisco in the North Coast Ranges, although there are populations in the * Supported in part by NIH training grant GMoo7oi -Financial support towards publication is gratefully acknowledged (ed.).

A Re-examination of the Alkaloids of Lupinus cosentinii

“…Esters of 13-hydroxymultiflorine are also absent from the seed and appear to have been converted, at least in part, to the free base. Published data on North American lupins (17) and our own unpublished data on other Mediterranean lupins suggest that alkaloid patterns may vary considerably within an apparently homogeneous species. By contrast L. cosentinii seems to be a species with a stable alkaloid pattern.…”

Variation in Lupinus arboreus alkaloid profiles and relationships with multiple herbivores

“…Quinolizidine alkaloids have broad-spectrum effects against pathogens, insects, and vertebrate herbivores (Mankinen et al, 1975;Wink, 1992;Wink and Latz-Bruning, 1995). The population of L. arboreus at our study site experiences spatial and temporal variability in herbivory and damage to individual plants and among lupine stands can vary dramatically.…”
