Adaptive paternal effects? Experimental evidence that the paternal environment affects offspring performance.
The ability of females to adaptively influence offspring phenotype via maternal effects is widely acknowledged, but corresponding nongenetic paternal effects remain unexplored. Males can adjust sperm phenotype in response to local conditions, but the transgenerational consequences of this plasticity are unknown. We manipulated paternal density of a broadcast spawner (Styela plicata, a solitary ...
متن کاملExperimental evidence for paternal effects on offspring growth rate in Arctic charr (Salvelinus alpinus).
Sexual selection theory predicts that females should choose males that signal viability and quality. However, few studies have found fitness benefits among females mating with highly ornamented males. Here, we use Arctic charr (Salvelinus alpinus), a teleost fish with no parental care, to investigate whether females could gain fitness benefits by mating with highly ornamented and large-sized ma...
متن کاملPaternal Behavior and Offspring Aggression
Aggression can have a critical impact on the functioning of societies. Some aspects of aggression have received considerable attention, such as links between parenting behavior and offspring aggression in humans. Although acknowledged as being important to the understanding of human aggression, animal aggression has been relatively unstudied. Recent mammalian animal research is emerging that ad...
متن کاملContrasting Effects of Maternal and Paternal Age on Offspring Intelligence
Both maternal and paternal ages are increasing in the developed world. The average age of mothers at time of childbirth has increased from 26.4 years in 1974 to 29.3 years in 2002, while the average age of fathers has increased from 29.2 years in 1980 to 32.1 years in 2002 [1]. This increase in the average parental age is most likely due to the societal trend for couples to delay starting a fam...
متن کاملPaternal social enrichment effects on maternal behavior and offspring growth.
Paternal environmental experiences are significant predictors of developmental outcomes in offspring and can occur even in the absence of paternal care. Although there has been a recent focus on the role of environmentally induced changes in the male germline in producing these effects, the potential mediating role of mothers has not been investigated. A role for mothers in the transmission of ...
