“…Finally, there is evidence that investment into current reproduction increases with the age of the female parent in N. orbicollis as predicted by the terminal investment hypothesis (Creighton et al, 2009). Thus, if handicapping leads to terminal investment, we might have expected weighted females to gain less weight during breeding, as this trait is used as a proxy for investment in future reproduction (Creighton et al, 2009;Billman et al, 2014). We found no evidence that weighted females lost more weight during the breeding period than control females, suggesting that our results provide no overall support for terminal investment triggered by handicapping.…”

“…Our main aim was to examine joint effects of handicapping and brood size on the overall level of care provided by females and on female weight change during breeding. The latter is used as a proxy for how much females consume from the carcass to invest into their future reproduction (Creighton et al, 2009;Billman et al, 2014). We expect an effect of the interaction between handicapping and brood size only if handicapping leads to a greater divergence in the cost function at higher levels of care ( Fig.…”

“…These two scenarios focus on how parents might adjust their investment during the current breeding attempt, but these adjustments might also have implications for future reproduction, which will in turn contribute to population dynamics. Parents that increase their overall investment in current reproduction are expected to suffer future costs in the form of a smaller second brood (Creighton et al 2009;Ward et al 2009;Billman et al 2014), whereas there might not be any future costs associated with merely adjusting the trade-off between number and size of offspring. Theoretical modeling and long-term field studies are now needed to better understand these dynamics.…”

“…Prehatching care includes preparation of the carcass and investment of nutrients in eggs (Rozen et al 2008;Monteith et al 2012), while posthatching care includes brood defense, secretion of antimicrobials, and food provisioning (Eggert et al 1998;Smiseth et al 2003;Rozen et al 2008). Last, there is evidence for a trade-off between investment in current and future reproduction in N. vespilloides and the related Nicrophorus orbicollis: females that overproduce offspring in the first breeding attempt suffer a reduction in fecundity in future breeding attempts (Creighton et al 2009;Ward et al 2009;Billman et al 2014).…”

“…For example, the use of valuable resources, such as carrion or dung, as food source by the developing young might promote the evolution of parental care and family life, as offspring benefit from parental protection against competitors. However, family living might also be fostered on such resources by direct parental benefits: each parent might benefit personally from staying and defending the resource, as it enables them to feed from a high-quality diet, thereby enhancing self-maintenance and future reproductive opportunities (Creighton et al, 2009;Billman et al, 2014;Pilakouta et al, 2016;Chemnitz et al, 2017). However, if such a shared food source is limited, competition over its consumption might ensue between the family members, as each party will benefit from consuming more resources than is in the interest of the other members (Pilakouta et al, 2016).…”
