The cumulative cost of reproduction hypothesis predicts that reproductive
costs accumulate over an individual’s reproductive lifespan. While
short-term costs have been extensively explored, the prevalence of
cumulative long-term costs and the circumstances under which such costs
occur alongside or instead of short-term costs, are far from clear.
Indeed, few studies have simultaneously tested for both short-term and
cumulative long-term reproductive costs in natural populations. Even in
mammals, comparatively little is known about cumulative effects of
previous reproduction, especially in species with high variation in
offspring numbers, where costs could vary among successful reproductive
events. Here, we quantify effects of previous short-term and cumulative
long-term reproduction on current reproduction probability and litter size
in wild female yellow-bellied marmots (Marmota flaviventer), and test how
these effects vary with age and between two contrasting environments. We
provide evidence for cumulative long-term effects: females that had both
reproduced frequently and weaned large litters on average in previous
years had decreased current reproduction probability. We found no evidence
for short-term reproductive costs between reproductive bouts. However,
females weaned larger litters when they had weaned larger litters on
average in previous years, and had lower current reproduction probability
when their previous reproductive success was low. Together these results
suggest that, alongside persistent among-individual variation, long-term
reproductive history affects current reproductive success.
