Transgenerational Effects of Maternal Age on Offspring Fitness in Crickets
… can have both positive and negative effects on offspring fitness, and thus, parental age can be considered a parental effect. As a parental effect, parental age may affect a variety of offspring traits and may cascade to influence several generations of offspring. Given the complexities of …

Qualitative and Quantitative Fitness Consequences of Advanced Maternal Age
<p>Parental age can affect offspring fitness across taxa and through various mechanisms. However, the effect(s) of advanced maternal age on offspring, particularly in insects, has not been comprehensively reviewed making it difficult to draw conclusions about the effects of advanced maternal age on …

Social Determinants of Immature Phenotype and Survival in Wild Baboons and Other Mammals
… of understanding all the factors contributing to offspring survival in a single species may seem hopelessly challenging, even in a relatively well-studied model organism living under controlled conditions. This challenge is even greater when considering free-living animals that are subject to …

Effects of Inbreeding on Endangered Red Wolves (Canis rufus)
Inbreeding depression, the reduction in offspring fitness caused by mating among close relatives, is widespread in small populations and a major concern in conservation biology because it can affect population persistence. The negative effects of inbreeding results in the evolution of inbreeding …

The population biology of Ligia oceanica (L.)(Crustacea: Oniscoidea)
… to alter egg size seasonally may optimise total offspring fitness in the different environments they experience.(ii) An ability of small, mature females to delay reproduction until the following year may also increase their fitness. By assuming that offspring survival is related to egg size it is …

Evolutionary and proximate constraints on egg size in butterflies
… that are assumed to strongly shape variation in offspring size and number: maternal size and maternal nutrition. Both are assumed to affect reproductive traits and thereby maternal and offspring fitness. Phenotypic correlations between maternal size and egg size within various butterfly species …

Sexual conflict and division of labour during incubation
… and between care of current and future offspring. Within a biparental system, models predict that an individual will do better if it can reduce its own level of investment and rely on its partner to compensate, but that the partner should not compensate completely or it will be …

The neural regulation of fatherhood, insights from the anemonfish amphiprion ocellaris
… animal kingdom, and when present is critical for offspring survival. Parental care represents a conflict: should parents invest in offspring fitness at the consequence of forgone reproductive opportunities? Or should they relinquish their parental duties in pursuit of additional mating events and …

Fitness and Implications of Reproductive Decisions for Black Brant Nesting on the Yukon-Kuskokwim Delta, Alaska
… mate loss might be expected to reduce fitness, either through reduced survival or reduced future reproductive investment. In the second chapter, human harvest of male brant was used as an experiment to examine effects of mate loss on fitness of female brant. Nineteen years of …
