Mean population growth (multiplication rate, logged) per unit time (hour), of fast- and slow-killing virus strains. Over 8 h, host availability was less limited, resulting in higher relative population growth rate of the higher transmitting and less virulent (slow-killing) populations, whereas hosts were more limiting over 24 h, resulting in higher population growth of the lower transmitting and virulent (fast-killing) populations. Data are means (n = 6) ± s.e.m.
