Habitat Structure Influences Parent-Offspring Association in a Social Lizard

Habitat Structure Influences Parent-Offspring Association in a Social Lizard

Parental care emerges as a result of an increase in the extent of interaction between parents and their offspring. These interactions can provide the foundation for the evolution of a range of complex parental behaviors. Therefore, fundamental to understanding the evolution of parental care is an understanding of the factors that promote this initial increase in parent-offspring association. He...

Strong Parent–Offspring Association of Metabolic Syndrome in Korean Families

OBJECTIVE To investigate the associations of metabolic syndrome (MetS) and its components between adolescents and their parents in Korea. RESEARCH DESIGN AND METHODS We analyzed data for 4,657 subjects (1,404 fathers, 1,404 mothers, 957 sons, and 892 daughters) from the Korean National Health and Nutrition Examination Surveys conducted between 1998 and 2008. RESULTS Compared with adolescent...

Natal social environment influences habitat selection later in life

Parent–offspring conflict

Is this soap opera or science? It can be both, but in evolutionary biology it refers to the subtly different ways natural selection acts on genes expressed in parents and their offspring. To give a concrete example, consider a parent with two offspring: other things being equal, the parent is likely to be under natural selection to give equal amounts of food to each of its young. But natural se...

Gestational diabetes influences retinal Muller cells in rat's offspring

Objective(s): The Muller cell is the principal glial cell of the vertebrate retina. The expression of Glial fibrillary acidic protein (GFAP) in the Muller cells was used as a cellular marker for retinal damage. This study was done to evaluate the effect of gestational diabetes on retinal Muller cells in rat's offspring. Materials and Methods: In this experimental study, 12 Wistar rat dams were ...
