Effects of competition and predation risk from a life history intraguild predator on individual specialisation

Individuals can deploy a variety of ecological and behavioural strategies to obtain resources, often using only a subset of the total resource diversity used by their population. This phenomenon of individual specialisation (IS) is nearly ubiquitous across taxa, and has the potential to affect population dynamics and ecosystem processes. Pairwise antagonistic interactions such as competition and predation can influence the degree of IS in a population, but little is known about the combined effects of multiple simultaneous interaction types between species, including intraguild predation (competition and predation from a single antagonist). 
We address this gap by asking how the combination of competition and predation risk from an invasive intraguild predator – Eurasian perch Perca fluviatilis – impacts the degree of dietary and habitat IS in a native New Zealand fish, the common bully Gobiomorphus cotidianus. Bullies exhibit a generalised diet at the population level and compete ..., , # Effects of competition and predation risk from a life history intraguild predator on individual specialisation

## Description of the data and file structure

Data from mesocosm study on effects of small perch (competitor) and large perch (predation risk) on individual common bully diet and habitat use. Diet and habitat are stored in separate spreadsheets, each with a detailed R script that walks through all analyses used in the manuscript.
