Defence variation within a guild of aphid-tending ants explains aphid population growth

1. RScript_field experiments: R Script to calculate the probabilities of aphid natural enemies of being ejected from thistles by the ant Dorymyrmex tener. Data is available in 'data_field experiments.txt'2. RScript_ant exclusion experiments: R Script to calculate the effect of the ant Dorymyrmex tener on aphid density and the abundance of aphid natural enemies on thistles. Data is available in 'data_ant exclusion experiments'3. RScript_ladybug encounters: R Script to calculate ant species aggressiveness toward ladybugs. Data is available in 'data_ladybug encounters'4. RScript_syrphid larvae encounters: R Script showing how to calculate ant species aggressiveness toward syrphid larvae. Data is available as 'data_syrphid larvae encounters.txt'5. RScript_aphid intrinsic rate of increase: R Script used to calculate aphid intrinsic rate of increase. Data is available as 'Data_aphid intrinsic rate of increase.txt.'
