Host radiation refers to the ability of parasites to adapt to new environments and expand or change their niches. Adaptation to one specific environment may involve a loss in adaptation to a second environment. Thus, fitness costs may impose limits to niche expansion and constitute the cost of specialization. Several reports have addressed the cost of host radiation in vesicular stomatitis virus (VSV), but in some cases the experimental setup may have resulted in the overestimation of fitness… CONTINUE READING
