| T23 |
0-155 |
Sentence |
denotes |
Alternatively, the “tradeoff” hypothesis suggests that there is some intermediate level of parasite virulence [3,6,14] that is optimal for a given setting. |
| T24 |
156-276 |
Sentence |
denotes |
In this scenario, too high a virulence kills the host and parasite and too low a virulence leads to failure to transmit. |
| T25 |
277-499 |
Sentence |
denotes |
Applying this hypothesis specifically to free-living survival would suggest that selection for increased free-living survival should come at the expense of virulence (producing a pathogen that is less harmful to the host). |
| T26 |
500-642 |
Sentence |
denotes |
Mechanistically, as a consequence of increased adaptation to a nonhost environment, a virus may be less fit to replicate inside a host [9,15]. |
| T27 |
643-789 |
Sentence |
denotes |
For example, a more robust viral capsid may help to survive harsh environmental conditions but may make it more difficult to package RNA/DNA [15]. |
| T28 |
790-977 |
Sentence |
denotes |
More generally, the tradeoff hypothesis can be framed in the context of a life-history tradeoff: investment in certain parts of the life cycle often comes at the expense of others [2,16]. |
