Individual behaviour, growth, survival and vulnerability to hunting in a large mammal

Humans have exploited wild animals for thousands of years. Recent studies indicate that harvest-induced selection on life-history and morphological traits may lead to ecological and evolutionary changes. Less attention has been given to harvest-induced selection on behavioural traits, especially in terrestrial systems. We assessed in a wild population of large terrestrial mammals whether decades of hunting led to harvest-induced selection on trappability, a proxy of risk-taking behaviour. We investigated links between trappability, horn growth and survival across individuals in early life and quantified the correlations between early life trappability and horn growth with availability to hunters and probability of being shot. We found positive among-individual correlations between early life trappability and horn growth, early life trappability and survival, and early life horn growth and survival. Faster growing individuals were more likely to be available to hunters and shot at a youn..., , , # Individual behaviour, growth, survival and vulnerability to hunting in a large mammal

This data set was collected for males of a wild bighorn sheep population. It contains information on rams early life behavior, growth and survival as well as two measures of their vulnerability to hunting later in life.

## Description of the data and file structure

All the necessary data are contained in a single csv file where:

* ID, is the individual identity of each ram.
* Year, is a grouping variable regrouping every observations that were taken in the same year.
* Cohort, is a grouping variable regrouping rams that were born the same year.
* Age, is the age of rams in years when the measures was taken.
* PopSize, is the total population size when the measure was taken.
* MeanPopSize, is the mean population size individuals experienced from ages 1 to 4.
* Trappability, is the annual number of captures of rams in a corral trap baited with salt.
* HornGrowth, is the annual growt...
