Biological invasions have become one of the most important drivers of
biodiversity loss and ecosystem change world-wide. However, it is still
unclear how invasions may interact with local abiotic stressors, which are
expected to increase as global change intensifies. Furthermore, we know
little about the response to biological invasions of insects, despite
their disproportionate contribution to global animal biodiversity. The aim
of the present work is to investigate the impact of an invasive aquatic
insect on the co-occurrence patterns of native species of insects along a
salinity gradient, and determine which assembly rules are driving these
patterns. First, we characterised the habitat specialisation and
functional niches of each species from physiological and biological
traits, respectively, and their degree of overlap. Second, we used field
data to compare the co-occurrence patterns of native and invasive species
in invaded and non-invaded areas of southern Iberia and northern Morocco.
Finally, we tested if habitat filtering or niche differentiation assembly
rules mediate their co-occurrence. In non-invaded areas, habitat filtering
drives habitat segregation of species along the salinity gradient, with a
lower contribution of niche differentiation. The presence of the invasive
insect modifies the distribution and co-occurrence patterns of native
species. In invaded areas, niche differentiation seems to be the main
mechanism to avoid competition among the invasive and native species,
enabling coexistence and resource partitioning. The combined study of
functional niche similarity and abiotic stressor tolerance of invasive and
native species can improve our understanding of the effects of invasive
species along abiotic stress gradients. This approach may increase our
capacity to predict the outcomes of biological invasion in a global change
context.
