The extent of inbreeding depression and the magnitude of
heterozygosity–fitness correlations (HFC) have been suggested to depend on
the environmental context in which they are assayed, but little evidence
is available for wild populations. We combine extensive molecular and
capture–mark–recapture data from a blue tit (Cyanistes caeruleus)
population to (1) analyze the relationship between heterozygosity and
probability of interannual adult local recruitment and (2) test whether
environmental stress imposed by physiologically suboptimal temperatures
and rainfall influence the magnitude of HFC. To address these questions,
we used two different arrays of microsatellite markers: 14 loci classified
as neutral and 12 loci classified as putatively functional. We found
significant relationships between heterozygosity and probability of
interannual local recruitment that were most likely explained by variation
in genomewide heterozygosity. The strength of the association between
heterozygosity and probability of interannual local recruitment was
positively associated with annual accumulated precipitation. Annual mean
heterozygosity increased over time, which may have resulted from an
overall positive selection on heterozygosity over the course of the study
period. Finally, neutral and putatively functional loci showed similar
trends, but the former had stronger effect sizes and seemed to better
reflect genomewide heterozygosity. Overall, our results show that HFC can
be context dependent, emphasizing the need to consider the role of
environmental heterogeneity as a key factor when exploring the
consequences of individual genetic diversity on fitness in natural
populations.
DataBaseThe file contains the information about blue tit individuals
captured in consecutive years in two populations located in center of
Spain. Data base shows informaction for each individual about; sex,
location, age, physical condition, local-immigrant status and if they were
captured in the following year. It also shows the genetic diversitiy
indexes for the set of all markers, neutral markers and functional markers
separately, as well as genetic information about each microsatellite.
