1. Environments change rapidly, and it is unclear whether organisms with
complex life-styles, such as avian migrants, are able to adjust
sufficiently. For understanding human impacts on ecosystem functioning, it
is crucial to understand how well, and by which mechanisms species are
able to adapt. 2. To improve the understanding of migrants’ ability to
adjust their annual timing to climate change, we investigated ontogenetic
hatch date effects on adult spring migration timing and female egg laying
dates. We experimentally delayed hatch dates of pied flycatchers Ficedula
hypoleuca by one week in three breeding seasons by delaying incubation
onset. We investigate if natural and experimental (shifts in) hatch date
affected timing of recruiting individuals up to at least three years after
the manipulation. 3. Spring arrival dates were positively correlated to
natural variation in hatch dates in three of the five years considered,
but no such effects were found in egg laying. Experiments showed that
delayed hatching resulted in delayed arrival and laying only in one-year
old and not in older birds. These effects were mostly observed during one
of the study years. 4. The discrepancy between experimental and natural
hatch date effects indicate that a causal hatch date effect is not
generally responsible for the correlation between hatch date and timing
during adulthood. Instead, we propose that natural hatch date effects on
spring arrival arise from genetic variation in migration schedules, while
delays in hatching induced carry-over effects on arrival and laying dates
in offspring (e.g. the experimental effect in 2010). Strong support for
year-specific expression of hatch date and delay effects on time schedules
imply that trait-variation can be easily obscured. The latter may explain
the lack of hatch date effects on female egg laying. 5. Our results imply
that plasticity in breeding phenology does not provide pied flycatchers
with a non-genetic inheritance route to rapidly advance annual cycles.
Instead, plasticity may rather masks (genetic) trait-variation for
selection to act on, and thereby slow down micro-evolutionary adaptation
to changing environments.
timing1_descriptiveA descriptive dataset with field data used to study
timing of arrival and laying of pied flycatchers, Ficedula hypoleuca, in
relation to their date of hatching (at birth), as studied in a breeding
population in Drenthe (The Netherlands). This includes chicks born in
2007-2013 that did not perceive experimental delay treatments, and that
arrived and/or laid their eggs at least once in
2010-2014.timing2_experimentalAn experimental dataset with field data used
to study timing of arrival and laying of pied flycatchers, Ficedula
hypoleuca, in relation to their date of hatching (at birth), as studied in
a breeding population in Drenthe (The Netherlands). This includes chicks
born in 2009-2011 that were part of a delayed hatching experiment (i.e. a
control or delay treatment), and that arrived and/or laid their eggs at
least once in 2010-2014.survival_experimentalA dataset with pied
flycatcher chicks born in 2009-2011 within the delayed hatching experiment
(as control or delay) in relation to their treatment, body weight and
'survival'.README
