| • Host age: infestation & mortality & distribution • One hypothesis:
 ○ Older: infestation ↑
 § More time to accumulate parasites
 • Another:
 ○ Older: lower infestation
 § Immune↑ & mortality of youngers
 • Author
 ○ Infestation → survival changes
 ○ Gerbils
 § Partial support
 □ Infestation and distribution: same
 □ Mortality:  younger( ↓48%)
 ○ Effect of age: not in differences in recruitment and motarlity
 § But also: other traites
 □ recruitment and mortality:  opposite direction
 ® e.g.wood mice
 ◊ Adult : recruitment↑  BUT  better immune
 □ Other factors:  exposure,immune ,hostmortality
