Why is it that some parasites cause high levels of host damage (ie virulence) whereas others
are relatively benign? There are now numerous reviews of virulence evolution in the …

Infections that consist of multiple parasite strains or species are common in the wild and are
a major public health concern. Theory suggests that these infections have a key influence on …

Parasites and infectious diseases are everywhere and represent some of the most potent
forces shaping the natural world. They affect almost every aspect imaginable in the life of …

Up to now in our study of continuous population models we have been assuming that x (t),
the growth rate of population size at time t, depends only on x (t), the population size at the …

The hypothesis of group selection fell victim to a seemingly devastating critique in 1960s
evolutionary biology. In Unto Others (1998), we argue to the contrary, that group selection is …

At a time of unprecedented expansion in the life sciences, evolution is the one theory that
transcends all of biology. Any observation of a living system must ultimately be interpreted in …

It has been more than two decades since the formulation of the so‐called 'trade‐
off'hypothesis as an alternative to the then commonly accepted idea that parasites should …

Several evolutionary processes influence virulence, the amount of damage a parasite
causes to its host. For example, parasites are favored to exploit their hosts prudently to …

Recent studies suggest that parasites (interpreted broadly to include viruses, bacteria,
protozoans and helminths) may influence the numerical magnitude or geographical …

The evolution of competitive interactions among viruses was studied in the RNA phage φ6 at
high and low multiplicities of infection (that is, at high and low ratios of infecting phage to …
