“…The significantly greater parallel evolution of AL relative to FL morphotypes after week 10 (figure 5.4) suggests that they at least follow different adaptive trajectories, and not simply "catch up" with the FL types later. The emergence of FL morphs has been reported in various species of Aspergillus grown under similar glucose limiting conditions as in our study (Swift et al, 2000;Withers et al, 1994).…”

(A) Resource quality, (B) Resource durability, (C) Presence of multiple individuals. (D) Describes general conditions for a tradeoff between mycelial growth rate and asexual spore yield. The alternate strategies mentioned in (A-C) are not necessarily mutually exclusive and most fungi are likely to employ a combination of these strategies based on ecology and organismal biology.
