Description

From the Introduction ... 'The vegetation mosaic in any landscape is a function of environmental variation and historic disturbances, whether caused by humans or other factors. Many studies have focused on species composition in relation to environmental gradients, and secondary succession is one of the oldest themes in ecology....Ecological research on landscapes, with its focus on the causes and significance of patterns beyond the scale of single stands or isolated communities, has been stimulated in part by human-caused landscape fragmentation....My objective is to explore the potential effects of certain insects, fungi, and parasitic angiosperms on landscape pattern in forested wildlands, with the belief that studying such interactions can lead to the improved management of landscapes in which forests are being fragmented by timber harvesting or homogenized due to the fire suppression. I'll focus on parasites (sensu lato) and fire because (1) their interaction is interesting and widespread, (2) both can have significant effects on vegetation mosaics, and (3) both are often subjected to control measures. I emphasize the mosaic in wildlands because wilderness landscapes were the setting for the evolution of our biota and are changing due to human interferences. Understanding the causes and significance of the vegetation mosaic of wildlands may help in the design of domesticated landscapes. coniferous forest are emphasized because of the literature available, but brief comparisons will be made to other vegetation types.'
