Mongolian cattle from China have strong adaptability and disease resistance. We aimed to compare the gut microbiota community structure and diversity in grazing Mongolian cattle from different regions in Inner Mongolia and to elucidate the influence of geographical factors on the intestinal microbial community structure. We used high throughput 16S rRNA sequencing to analyze the fecal microbial community and diversity in samples from 60 grazing Mongolian cattle from Hulunbuir Grassland, Xilingol Grassland, and Alxa Desert. A total of 2,720,545 high-quality reads and sequences that were 1,117,505,301 bp long were obtained. Alpha diversity among the three groups showed that the gut microbial diversity in Mongolian cattle in the grasslands was significantly higher than that in the desert. The dominant phyla were Firmicutes and Bacteroidetes, whereas Verrucomicrobia presented the highest abundance in the gut of cattle in the Alxa Desert. The gut bacterial communities in cattle from the grasslands versus the Alxa Desert were distinctive, and those from the grasslands were closely clustered. Community composition analysis revealed significant differences in species diversity and richness. Overall, the composition of the gut microbiota in Mongolian cattle is affected by geographical factors. Gut microbiota may play important roles in the geographical adaptations of Mongolian cattle.

The first of the research objectives discussed in this article was to analyze the differences related to the valuation of particular factors influencing the purchase process in the smartphone industry, expressed by respondents with different sensitivity and environmental awareness, as well as the assessment of their knowledge about the impact of smartphones on the natural environment. The second objective of the research was to determine whether the level of environmental sensitivity, awareness and knowledge about the impact of smartphones on the environment has a statistically significant influence on the respondents’ choice of smartphone brand. The survey was conducted using an on-line questionnaire, distributed by a specialized research agency on a representative sample of over 1000 Polish residents. In order to identify the various customers clusters, the expectation-maximization algorithm and the v-fold cross-validation were used. Additionally, in order to analyze the significance level of differences between clusters the nonparametric Mann-Whitney U-test was carried out. The results show unequivocally that people with a different approach to ecological issues demonstrate statistically significant differences in their purchasing behaviors in the smartphone industry. Furthermore, it was noticed that in the case of comparing some smartphones brands, there is a statistically confirmed difference in the environmental sensitivity and awareness of the customers who use them. Moreover, the research has shown that in Polish customers’ consciousness smartphones are mistakenly considered to be relatively safe and environmentally friendly products.

AbstractSome children are more affected than others by their upbringing due to their increased sensitivity to the environment. More sensitive children are at heightened risk for the development of internalizing problems, particularly when experiencing unsupportive parenting. However, little is known about how the interplay between children’s sensitivity and parenting leads to higher levels of depressive symptoms. In the current study, we investigated the interaction between early parenting and children’s sensitivity on levels of depressive symptomatology in middle childhood, exploring the role of rumination as a possible mediator in a community sample. Participants included 196 USA resident families, from a middle class and mostly European–American background, and their healthy children, followed up from age 3 until 9 and 12 years. Environmental sensitivity was assessed observationally when children were 3 years old. Parenting style was based on parent-report at the age of 3 years. When children were nine, they completed questionnaires on rumination and depressive symptoms (repeated at 12 years). Analyses were run applying a Bayesian approach. Children’s sensitivity interacted with permissive parenting in predicting rumination at age 9. Rumination, in turn, was associated with depressive symptoms at age 9 and, to a lesser extent, at age 12. No relevant interactions emerged for authoritative and authoritarian parenting. Sensitive children may be at heightened risk for internalizing problems when exposed to a permissive parenting style. Permissive parenting was associated with increased ruminative coping strategies in sensitive children which, in turn, predicted higher levels of depression. Hence, rumination emerged as an important cognitive risk factor for the development of depressive symptoms in sensitive children.
