Abstract
Recent developments in understanding and predicting species responses to climate change have emphasised the importance of both environmental variability and consideration of the wider biotic community. To date, the interaction between the two has received less attention. However, considerable bodies of theory and empirical results suggest that multi-species consequences of variability can have strong impacts on range limits and the speed of range shifts. Here we demonstrate how biotic interactions and temporal variability can act together to influence range shift dynamics and highlight the need to understand these interactions in order to predict how species will respond to global change. We emphasise the value and utility of partitioning approaches applied to parameterised models to determine the direction and relative importance and direct of these forces in empirical systems.
