Stepfamily Structure and Transfers Between Generations in U.S. Families.

ABSTRACT: Unstable couple relationships and high rates of repartnering have increased the share of U.S. families with stepkin. Yet data on stepfamily structure are from earlier periods, include only coresident stepkin, or cover only older adults. In this study, we use new data on family structure and transfers in the Panel Study of Income Dynamics (PSID) to describe the prevalence and numbers of stepparents and stepchildren for adults of all ages and to characterize the relationship between having stepkin and transfers of time and money between generations, regardless of whether the kin live together. We find that having stepparents and stepchildren is very common among U.S. households, especially younger households. Furthermore, stepkin substantially increase the typical household's family size; stepparents and stepchildren increase a household's number of parents and adult children by nearly 40 % for married/cohabiting couples with living parents and children. However, having stepkin is associated with fewer transfers, particularly time transfers between married women and their stepparents and stepchildren. The increase in the number of family members due to stepkin is insufficient to compensate for the lower likelihood of transfers in stepfamilies. Our findings suggest that recent cohorts with more stepkin may give less time assistance to adult children and receive less time assistance from children in old age than prior generations.

Project description:BACKGROUND:Plants are colonized by a great diversity of microorganisms which form a microbiota and perform additional functions for their host. This microbiota can thus be considered a toolbox enabling plants to buffer local environmental changes, with a positive influence on plant fitness. In this context, the transmission of the microbiota to the progeny represent a way to ensure the presence of beneficial symbionts within the habitat. Examples of such transmission have been mainly described for seed transmission and concern a few pathogenic microorganisms. We investigated the transmission of symbiotic partners to plant progeny within clonal plant network. METHODS:We used the clonal plant Glechoma hederacea as plant model and forced newly emitted clonal progeny to root in separated pots while controlling the presence of microorganisms. We used an amplicon sequencing approach of 16S and 18S rRNA targeting bacteria/archaea and fungi respectively to describe the root microbiota of mother and clonal-plant offspring. RESULTS:We demonstrated the vertical transmission of a significant proportion of the mother plants' symbiotic bacteria and fungi to the daughters. Interestingly, archaea were not transmitted to the daughter plants. Transmitted communities had lower richness, suggesting a filtration during transmission. We found that the transmitted pool of microorganisms was similar among daughters, constituting the heritability of a specific cohort of microorganisms, opening a new understanding of the plant holobiont. We also found significant effects of distance to the mother plant and of growth time on the richness of the microbiota transmitted. CONCLUSIONS:In this clonal plant, microorganisms are transmitted between individuals through connections, thereby ensuring the availability of microbe partners for the newborn plants as well as the dispersion between hosts for the microorganisms. This previously undescribed ecological process allows the dispersal of microorganisms in space and across plant generations. As the vast majority of plants are clonal, this process might be therefore a strong driver of ecosystem functioning and assembly of plant and microorganism communities in a wide range of ecosystems.
