Environmental changes may stress organisms and stimulate an adaptive
phenotypic response. Effects of inbreeding often interact with the
environment and can decrease fitness of inbred individuals exposed to
stress more so than that of outbred individuals. Such an interaction may
stem from a reduced ability of inbred individuals to respond plastically
to environmental stress; however, this hypothesis has rarely been tested.
In this study, we mimicked the genetic constitution of natural inbred
populations by rearing replicate Drosophila melanogaster populations for
25 generations at a reduced population size (10 individuals). The
replicate inbred populations, as well as control populations reared at a
population size of 500, were exposed to a benign developmental temperature
and two developmental temperatures at the lower and upper margins of their
viable range. Flies developed at the three temperatures were assessed for
traits known to vary across temperatures, namely abdominal pigmentation,
wing size, and wing shape. We found no significant difference in
phenotypic plasticity in pigmentation or in wing size between inbred and
control populations, but a significantly higher plasticity in wing shape
across temperatures in inbred compared to control populations. Given that
the norms of reaction for the noninbred control populations are adaptive,
we conclude that a reduced ability to induce an adaptive phenotypic
response to temperature changes is not a general consequence of inbreeding
and thus not a general explanation of inbreeding–environment interaction
effects on fitness components.
