Host-enemy interactions provide limited biotic resistance for a range-expanding species via reduced apparent competition

Aim: As species’ ranges shift poleward in response to anthropogenic change, they may lose antagonistic interactions if they move into less diverse communities, fail to interact with novel populations or species effectively, or if ancestral interacting populations or species fail to shift synchronously. We leveraged a poleward range expansion in a tractable insect host-enemy community to uncover mechanisms by which altered antagonistic interactions between native and recipient communities contributed to “high niche opportunities” (limited biotic resistance) for a range-expanding insect.
Location: North America, Pacific Northwest
Methods: We created quantitative insect host-enemy interaction networks by sampling oak gall wasps on 400 trees of a dominant oak species in the native and expanded range of a range-expanding gall wasp species. We compared host-enemy network structure between regions. We measured traits (phenology, morphology) of galls and interacting parasitoids, predicting gre..., , R (packages include: vegan, bipartite) , This README file was generated on 2023-09-07 by Kirsten Prior
