Short-term benefits, but transgenerational costs of maternal loss in an insect with facultative maternal care

Short-term benefits, but transgenerational costs of maternal loss in an insect with facultative maternal care.

A lack of parental care is generally assumed to entail substantial fitness costs for offspring that ultimately select for the maintenance of family life across generations. However, it is unknown whether these costs arise when parental care is facultative, thus questioning their fundamental importance in the early evolution of family life. Here, we investigated the short-term, long-term and tra...

Epigenetic mechanisms and the transgenerational effects of maternal care.

The transmission of traits across generations has typically been attributed to the inheritance by offspring of genomic information from parental generations. However, recent evidence suggests that epigenetic mechanisms are capable of mediating this type of transmission. In the case of maternal care, there is evidence for the behavioral transmission of postpartum behavior from mothers to female ...

Costs and Benefits of Competitive Traits in Females: Aggression, Maternal Care and Reproductive Success

Recent research has shown that female expression of competitive traits can be advantageous, providing greater access to limited reproductive resources. In males increased competitive trait expression often comes at a cost, e.g. trading off with parental effort. However, it is currently unclear whether, and to what extent, females also face such tradeoffs, whether the costs associated with that ...

Maternal satisfaction with maternal-infant nursing care in Campeche, Mexico.

OBJECTIVE Evaluate and compare maternal-satisfaction (global and areas) with maternal-child nursing care (MSMINC) and to explore the relationship of MSMINC with wait time, length of visit, and maternal age and education. METHODS Cross-sectional descriptive study comprising 213 mothers. Group 1 (n = 84), mothers of children aged <1 year, and Group 2 (n = 129), mothers of children between 1 and...
