Biological invasions provide unique opportunities for studying life
history trait changes over contemporary time scales. As spatial spread may
be related to changes in parasite communities, several hypotheses (such as
the evolution of increased competitive ability (EICA) or EICA-refined
hypotheses) suggest immune changes in invasive species along invasion
gradients. Although native hosts may be subject to similar changes in
parasite selection pressures, their immune responses have been rarely
investigated in invasion contexts. In this study, we evaluated immune
variations for invasive house mice Mus musculus domesticus, invasive black
rats Rattus rattus and native rodents Mastomys erythroleucus and Mastomys
natalensis along well-characterised invasion gradients in Senegal. We
focused on antibody-mediated (natural antibodies and complement) and
inflammatory (haptoglobin) responses. One invasion route was considered
for each invasive species, and environmental conditions were recorded.
Natural-antibody mediated responses increased between sites of
long-established invasion and recently invaded sites only in house mice.
Both invasive species exhibited higher inflammatory responses at the
invasion front than in sites of long-established invasion. The immune
responses of native species did not change with the presence of invasive
species. These patterns of immune variations do not support the EICA and
EICA refined hypotheses, and they rather suggest a higher risk of exposure
to parasites on the invasion front. Altogether, these results provide a
first basis to further assess the role of immune changes in invasion
success.
