摘要Tail autotomy incurs energetic costs, and thus, a
trade-off in resource allocation may lead to compromised
immunity in lizards. We tested the hypothesis that tailless
lizards will favor constitutive innate immunity responses
over an energetically costly inflammatory response. The
influence of fasting and colorful ornamentation was also
investigated. We experimentally induced tail autotomy in
the lizard Eutropis multifasciata and found that inflammation
was suppressed by tail loss, but not further affected by
fasting; the suppressive effect of colorful ornamentation was
manifested only in males, but not in females. Constitutive
innate immunity was not affected by any of these factors. As
expected, only costly inflammation was compromised, and a
less expensive constitutive innate immunity might be favored
as a competent first-line defense during energetically
demanding periods. After considering conventional tradeoffs
among tail regeneration and reproduction, further
extending these studies to incorporate disease risk and how
this influences escape responses to predators and future
reproduction would make worthwhile studies.
