Abstract The widespread human activity on Earth exerts strong selective pressures the species with which we coexist. Faced constant environmental change, respond mechanisms of adaptation, expansion, retraction or displacement. Species that establish new populations outside their former range as a result human-induced change are called 'neonatives'. Many birds now appear to be expanding ranges in response habitat modification and climate change.

Abstract When species undergo poleward range expansions in response to anthropogenic change, they likely encounter less diverse communities new locations. If low diversity provide weak biotic interactions, such as reduced competition or predation, range‐expanding may experience high niche opportunities. Here, we investigated if oak gall wasp follow a latitudinal gradient (LDG) and lower weaker interactions at the poles for community member, Neuroterus saltatorius . We performed systematic surveys of wasps on dominant oak, Quercus garryana , throughout most its range, from northern California Vancouver Island, British Columbia. On 540 trees 18 sites, identified 23 morphotypes three guilds (leaf detachable, leaf integral, stem galls). regressions between diversity, latitude, other abiotic (e.g. temperature) habitat patch size) factors reveal followed an LDG. To uncover patterns local first partial correlations morphotype occurrences within regions). then abundances co‐occurring are putatively competitive antagonistic. Q. ‐gall LDG, with higher latitudes, particularly loss detachable morphotypes. Detachable wasps, including species, co‐occurred trees, co‐occurrences expanded region. Abundances N. integral galls were negatively related, suggesting antagonistic interactions. Overall, found that LDGs create associations might facilitate ecological release member. Given ubiquity nature, moving into communities. Yet, understanding pattern provides is not well explored. Our large‐scale study documenting related phytophagous insects co‐occur host plant reveals opportunities Biogeographical important mechanisms contributing altered under range‐expansions.
