Transgenerational effects of parent and grandparent gender on offspring development in a biparental beetle species.
نویسنده
چکیده
Parental effects on offspring life-history traits are common and increasingly well-studied. However, the extent to which these effects persist into offspring in subsequent generations has received less attention. In this experiment, maternal and paternal effects on offspring and grand-offspring were investigated in the biparental burying beetle Nicrophorus vespilloides, using a split-family design. This allowed the separation of prenatal and postnatal transgenerational effects. Grandparent and parent gender were found to have a cumulative effect on offspring development and may provide a selection pressure on the division of parental investment in biparental species.

Why does it take two to tango? Lifetime fitness consequences of parental care in a burying beetle
In species that require parental care, each parent can either care for their offspring or leave them in the care of the other parent. For each parent this creates three possible parental care strategies: biparental care, uniparental (male or female) care, and uniparental desertion by either the male or female. The burying beetle, Nicrophorus orbicollis, typically exhibits biparental care of off...
متن کاملPaternal influences on offspring development: behavioural and epigenetic pathways.
Although mammalian parent-offspring interactions during early life are primarily through the mother, there is increasing evidence for the impact of fathers on offspring development. A critical issue concerns the pathways through which this paternal influence is achieved. In the present review, we highlight the literature suggesting several of these routes of paternal effects in mammals. First, ...

Environmental conditions experienced by parents are increasingly recognized to affect offspring performance. We set out to investigate the effect of parental larval diet on offspring development time, adult body size and adult resistance to the bacterium Serratia marcescens in Drosophila melanogaster. Flies for the parental generation were raised on either poor or standard diet and then mated i...

Stressful parental environments can influence offspring size and development either adaptively or maladaptively, yet little is known about species' differences in this complex aspect of phenotypic plasticity. We performed a reciprocal split-brood experiment to compare transgenerational plasticity in response to drought stress in two closely related annual plant species. We raised inbred replica...
