The hologenome theory of evolution (HTE), which is under fierce debate, presupposes that parts of the microbiome are transmitted from one generation to the next [vertical transmission (VT)], which may also influence the evolution of the holobiont. Even though bacteria have previously been described in early life stages of corals, these early life stages (larvae) could have been inoculated in the water and not inside the parental colony (through gametes) carrying the parental microbiome. How Symbiodinium is transmitted to offspring is also not clear, as only one study has described this mechanism in spawners...

PURPOSE: Early perceived pubertal timing and faster maturation have been linked to increased risk of adolescent substance use (SU), particularly for girls, but the mechanisms underlying this association are not well understood. We sought to replicate and extend findings from Westling et al. (2008) showing that peer deviance mediates the link between early puberty and SU with stronger pathways in the context of low parental knowledge of adolescents' whereabouts and activities. METHODS: Participants (n = 1,023; 52% female, 24% nonwhite, and 12% Hispanic) were recruited through middle schools...

BACKGROUND: Fussy eating is common in young children, often raising concerns among parents. The use of pressuring feeding practices may provoke or worsen child fussiness, but these practices could equally be a parent's response to child fussy eating. OBJECTIVE: In longitudinal analyses, we assessed directionality in the relation between fussy eating and parent's pressure to eat across childhood. METHODS: Study participants were 4845 mother-child dyads from the population-based Generation R cohort in the Netherlands...

Using combined linkage and association mapping, 26 stable QTL and six stable SNPs were detected across multiple environments for eight ear and grain morphological traits in maize. One QTL, PKS2, might play an important role in maize yield improvement. In the present study, one bi-parental population and an association panel were used to identify quantitative trait loci (QTL) for eight ear and grain morphological traits. A total of 108 QTL related to these traits were detected across four environments using an ultra-high density bin map constructed using recombinant inbred lines (RILs) derived from a cross between Ye478 and Qi319, and 26 QTL were identified in more than two environments...

Individual differences in a child's sensitivity to stress may influence whether youth exposed to trauma develop symptoms of psychopathology. We examined the interaction between HPA-axis reactivity to an acute stressor and exposure to different types of childhood trauma as predictors of mental health symptoms in a sample of youth. Youth (n = 121, ages 9-16; 47% female) completed a standardized stress task, including 5 post-stress salivary cortisol samples. Parents also completed the Child Behavior Checklist as a measure of child internalizing and externalizing symptoms in the past month, and completed the Early Trauma Inventory (ETI) as a measure of their child's trauma exposure...

Theoretical advances in the study of the development of aggressive behaviors indicate that parenting behaviors and child aggression mutually influence one another. This study contributes to the body of empirical research in this area by examining the development of child aggression, maternal responsiveness, and maternal harsh discipline, using 5-year longitudinal data from a nationally representative sample of Turkish children (n = 1009; 469 girls and 582 boys). Results indicated that: (i) maternal responsiveness and harsh discipline at age 3 were associated with the subsequent linear trajectory of aggression; (ii) reciprocally, aggressive behaviors at age 3 were associated with the subsequent linear trajectories of these two types of parenting behaviors; (iii) deviations from the linear trajectories of the child and mother behaviors tended to be short lived; and, (iv) the deviations of child behaviors from the linear trajectories were associated with the subsequent changes in mother behaviors after age 5...

Oxygen and nitrate availability as well as the presence of suitable organic or inorganic electron donors are strong drivers of denitrification; however, the factors influencing denitrifier abundance and community composition in pristine aquifers are not well understood. We explored the denitrifier community structure of suspended and attached groundwater microorganisms in two superimposed limestone aquifer assemblages with contrasting oxygen regime in the Hainich Critical Zone Exploratory (Germany). Attached communities were retrieved from freshly crushed parent rock material which had been exposed for colonization in two groundwater wells (12...

Relationships with parents and friends are important contexts for developing romantic relationship skills. Parents and friends may influence both the timing of involvement and the quality of romantic relationships. Three models of the joint influence of parents and friends (direct effects model, mediation model, and moderator model) have been proposed. The present study uses data from a longitudinal study (n = 1012; 49.8% female; 81.1% Caucasian) to examine how attachment and friendship quality at age 10 years predict romantic relationship involvement and quality at ages 12 and 15 years...

Laboratory selection with Vip3Aa of a field-derived population of Heliothis virescens produced >2040-fold resistance in 12 generations of selection. The Vip-Sel resistant population showed little cross-resistance to Cry1Ab and no cross-resistance to Cry1Ac. Resistance was unstable after 15 generations without exposure to the toxin. F1 reciprocal crosses between Vip-Unsel and Vip-Sel indicated a strong paternal influence on the inheritance of resistance. Resistance ranged from almost completely recessive (mean h = 0...

Carrion beetles in the genus Nicrophorus rear their offspring on decomposing carcasses where larvae are exposed to a diverse community of decomposer bacteria. Parents coat the carcass with antimicrobial secretions prior to egg hatch (defined as Pre-Hatch care) and also feed regurgitated food, and potentially bacteria, to larvae throughout development (defined as Full care). Here we partition the roles of pre- and post-hatch parental care in the transmission and persistence of culturable symbiotic bacteria to larvae...

Many studies have been shown that maternal stress during pregnancy and in early life period influences offspring in the behavioral and molecular aspects in human and animal models. Recent research has indicated that the environmental condition of males before conception has effects on next generations. We evaluated whether preconception paternal stress (PPS) could influence on hippocampal glucocorticoid receptor gene (GR), (NR3C1) expression, corticosterone response and behavioral outcomes of their offspring...

PURPOSE: We know very little about how transgender people create their families and the issues involved in these decisions. This qualitative study explored the parenting intentions and desires of 32 self-identified transgender individuals who want to become parents in the future. METHODS: Data were collected using an open-ended survey with 32 transgender men and transgender women regarding when and how they want to become parents in the future. RESULTS: We found that transgender individuals expressed specific desires for parenthood, such as biological relatedness and barriers to parenthood, such as physical limitations or lack of legal protections, which influence how transgender individuals choose to become parents in the future...

BACKGROUND: The past 20 years have seen distinct shifts in the way the participation of children and adolescents in research is viewed. This has been emphasized by the growing pediatric research enterprise. Additional information on children's and adolescents' experiences during research participation is needed to better inform researchers on the ethical conduct of research with this vulnerable population. AIMS: The objective of this analysis was to examine ethical issues in research with children and adolescents from their perspective as participants, including: assent, parental consent, risk perception, impact of research participation, and incentives...

Eruptive forest insects are highly influential agents of change in forest ecosystems, and their effects have increased with recent climate change. State-dependent life histories contribute significantly to the population dynamics of eruptive forest insect herbivores; however, the proximate mechanisms by which these species shift between states is poorly understood. Laboratory bioassays were conducted using the mountain pine beetle (Dendroctonus ponderosae) to determine the effect of maternal host selection on offspring host preferences, as they apply to population state-dependent behaviors...

OBJECTIVES: This longitudinal study examined the effect of emerging vocabulary production on the ability to produce the phonetic cues to prosodic prominence in babbled and lexical disyllables of infants with cochlear implants (CI) and normally hearing (NH) infants. Current research on typical language acquisition emphasizes the importance of vocabulary development for phonological and phonetic acquisition. Children with CI experience significant difficulties with the perception and production of prosody, and the role of possible top-down effects is, therefore, particularly relevant for this population...
