Pace of life predicts Trinidadian guppy parasite resistance and fecundity tolerance, but not mortality tolerance

Host defence against parasites can include limiting parasite growth, ‘resistance’, limiting the mortality cost of infection, ‘mortality tolerance’, and limiting the reproductive cost of infection, ‘fecundity tolerance’. Theoretically, these three host strategies have very different epidemiological and evolutionary outcomes. In particular, because of its positive effect on parasite population size, mortality tolerance should be under strong positive selection and may therefore be less variable between populations than either resistance or fecundity tolerance. Additionally, host investment in each strategy can be expected to differ between populations that experience different ecological conditions. Here, we tested how populations of Trinidadian guppies Poecilia reticulata from the upper and lower courses of three rivers responded to experimental infection with a novel strain of Gyrodactylus turnbulli. In line with theoretical predictions, we found that lower course populations, previousl..., , # Pace of life predicts Trinidadian guppy parasite resistance and fecundity tolerance, but not mortality tolerance

## Description of the data and file structure

Here we infected female guppies - Poecilia reticulata - from several different Trinidadian populations. We then dissected the females and counted their offspring.

**Description:** This is a csv file of the data from the experiment.

##### Variables

* MaternalID: Identify of the mother
* DateDissected: Date sample was dissected in YYYYMMDD format OrderDissected: For each day of dissection, order dissection occurred in (1 = 1st sample dissected on that date, 2 = 2nd, etc.)
* OffspringNumber: Number of offspring; since each offspring gets its own row, should be either 1 (with a stage in the next column) or 0 (mother had no offspring)
