The extent of this bias is greater when there is a high level of extrinsic mortality; this accounts for much the diversity in life-history patterns

I marshal evidence that asymptomatic host individuals maintain persistent populations of viral pathogens; that these pathogens replicate; that they are often extremely variable; that selection within hosts causes the evolution of pathogens better able

What, then, can biologists who study senescence do with the comparative method — an approach that dates back to Buffon, Locke, Plin

Most importantly, the genetics of yeast is highly-developed and readily applicable to the dissection of longevity. Two candidate longevity genes have al

A review of studies of plant demography reveals senescent declines in both annual and perennial plants, but also suggests that there are some plant species which may not be expected to show senescence. Thus, future com

Recent progress in studying the evolutionary biology of senescence has been made through the use of new species, such as . and ., because of the ease of working with them in the laboratory and because investigators have used the

In this paper we summarize the way in which crowding may have an immediate impact on longevity, either through the phenomenon known as dietary restriction or through alterations in the quality of the environment brought on by the presence of large numbers of individua
