As wild fish stocks decline worldwide, land-based fish rearing is likely to be of increasing relevance to feeding future human generations. Little is known about the structure and role of microbial communities in fish aquaculture, particularly at larval developmental stages where the fish microbiome develops and host animals are most susceptible to disease. We employed next-generation sequencin...

The child-rearing environment has drastically changed over the past fifty years. Many factors associated with the changes in the environment have resulted in heightened child-rearing anxiety among mothers. For example, advancement of industries, urbanization, and expansion of the information society have led to a change in family structure. Nuclear families that consist of only a few members ha...

OBJECTIVES Parental rearing behavior is one factor that influences the strength of resilience. In turn, resilience influences depression. However, it is unclear whether resilience has a mediating effect on the relationship between parental rearing and depression in adolescents with congenital heart disease (CHD). Therefore, the associations between parental rearing behavior and resilience and b...

The aim of the current study was to evaluate the effects of lavender (Lavandula angustifolia) powder as an herbal feed additive on growth performance, carcass traits, meat quality, jejunal histomorphology, and ileal microbial population in broiler chickens. A total of two hundred twenty one day-old male broiler chicks were used in a completely randomized design with five treatments and four rep...

The number of lambs sold per ewe mated in the breeding flock has a considerable impact on sheep operation profitability. This depends primarily on fertility, prolificacy (# of lambs), and lamb survival, mothering ability, milk production of the ewe and lamb growth rate. Optimal reproduction does vary by environment and management system – some sheep operations don’t want a lambing rate over 200...

An 11-year follow-up study explored the effects of paternal involvement in child rearing and maternal employment in prior years on grades and educational expectations of a group of white, middle-class adolescents from intact families. Past maternal employment was found to be a more powerful predictor of children's academic performance and expectations than was amount of father involvement. Part...

Physiological adaptation through acclimation is one way to cope with temperature changes. Biochemical studies on acclimation responses in ectotherms have so far mainly investigated consequences of short-term acclimation at the adult stage and focussed on adaptive responses. Here, we assessed the consequences of rearing Drosophila melanogasterat low (12°C), benign (25°C) and high (31°C) temperat...

Animal societies vary in the number of breeders per group, which affects many socially and ecologically relevant traits. In several social insect species, including our study species Formica selysi, the presence of either one or multiple reproducing females per colony is generally associated with differences in a suite of traits such as the body size of individuals. However, the proximate mecha...

BACKGROUND Parental rearing behavior is a significant etiological factor for the vulnerability of psychopathology and has been an issue of clinical research for a long time. For this scope instruments are important who asses economically recalled parental rearing behavior in a clinical practice. Therefore, a short German instrument for the assessment of the recalled parental rearing behavior Fr...
