Resumen:
Aim Parental care improves the survival of offspring and therefore has a
major impact on reproductive success. It is increasingly recognized that
coordinated biparental care is necessary to ensure the survival of
offspring in hostile environments, but little is known about the
influence of environmental fluctuations on parental cooperation.
Assessing the impacts of environmental stochasticity, however, is
essential for understanding how populations will respond to climate
change and the associated increasing frequencies of extreme weather
events. Here we investigate the influence of environmental stochasticity
on biparental incubation in a cosmopolitan ground-nesting avian genus.
Location Global.
Methods We assembled data on biparental care in 36 plover populations
(Charadrius spp.) from six continents, collected between 1981 and 2012.
Using a space-for-time approach we investigate how average temperature,
temperature stochasticity (i.e. year-to-year variation) and seasonal
temperature variation during the breeding season influence parental
cooperation during incubation.
Results We show that both average ambient temperature and its
fluctuations influence parental cooperation during incubation. Male care
relative to female care increases with both mean ambient temperature and
temperature stochasticity. Local climatic conditions explain
within-species population differences in parental cooperation, probably
reflecting phenotypic plasticity of behaviour.
Main conclusions The degree of flexibility in parental cooperation is
likely to mediate the impacts of climate change on the demography and
reproductive behaviour of wild animal populations.
