Abstract: Abstract The overproduction of offspring is commonly associated with high hatching failure and a mechanism for dispensing with surplus young. We used experimental evolution of burying beetle populations Nicrophorus vespilloides to determine causality in these… read more here.

Paternal investment with an uncertain future: effects of predator exposure on filial cannibalism and nesting behaviour

DOI: 10.1016/j.anbehav.2017.07.024
Abstract: Owing to trade-offs between investment in current and future reproduction, factors that diminish a parent's survival prospects, such as predation threat, are expected to increase investment in existing young. Nevertheless, effects of predation risk on… read more here.

DOI: 10.1016/j.anbehav.2018.03.003
Abstract: Although the consumption of one's own offspring is often viewed as maladaptive, under some circumstances this behaviour can be a beneficial way to terminate parental care. When the costs of providing care are extremely high… read more here.

DOI: 10.1016/j.beproc.2017.03.019
Abstract: A novel type of filial cannibalism has been reported in pipefishes, in which the eggs are absorbed through the male's brood-pouch epithelium. The present study explored the applicability of stable isotope analysis for the detection… read more here.

Mothers modify the cost of reproduction by dynamic changes in antioxidant function and filial cannibalism

DOI: 10.1098/rsbl.2022.0319
Abstract: Investment in current reproduction may negatively influence subsequent fitness. Oxidative stress has been proposed as a potential mediator of this trade-off between current and future reproductive success. However, evidence of reproduction causing oxidative stress is… read more here.
