Phylogenetic Effects

Insufficient calcium (Ca) or magnesium (Mg) in the diets of humans and animals has negative effects on health. Knowledge of the concentrations of Ca and Mg in edible crops can help inform the formulation of appropriate diets. There are large differences in shoot concentrations of both Ca ([Ca]shoot) and Mg ([Mg]shoot) between angiosperm orders. For example, relative to other angiosperms, commelinid monocot species generally have lower [Ca]shoot and [Mg]shoot; species from the Cucurbitales, Malvales and Brassicales generally have higher [Ca]shoot and [Mg]shoot; and species from the Oxalidales and Caryophyllales generally have higher [Mg]shoot but similar [Ca]shoot, which results in higher [Mg]shoot/[Ca]shoot quotients. In this paper the evolution of the combined traits of high [Mg]shoot and high [Mg]shoot/[Ca]shoot quotient in the Caryophyllales was resolved at the family level. All Caryophyllales families had high mean [Mg]shoot and [Mg]shoot/[Ca]shoot quotients, suggesting that both of these traits evolved in an ancient ancestor of all Caryophyllales families.

Abstract LTR retrotransposons comprise a major component of the genomes of eukaryotes. On occasion, retrotransposon genes can be recruited by their hosts for diverse functions, a process formally referred to as co-option. However, a comprehensive picture of LTR retrotransposon gag gene co-option in eukaryotes is still lacking, with several documented cases exclusively involving Ty3/Gypsy retrotransposons in animals. Here we use a phylogenomic approach to systemically unearth co-option of retrotransposon gag genes above the family level of taxonomy in 2,011 eukaryotes, namely co-option occurring during the deep evolution of eukaryotes. We identify a total of 14 independent gag gene co-option events across more than 740 eukaryote families, eight of which have not been reported previously. Among these retrotransposon gag gene co-option events, nine, four, and one involve gag genes of Ty3/Gypsy, Ty1/Copia, and Bel-Pao retrotransposons, respectively. Seven, four, and three co-option events occurred in animals, plants, and fungi, respectively. Interestingly, two co-option events took place in the early evolution of angiosperms. Both selective pressure and gene expression analyses further support that these co-opted gag genes might perform diverse cellular functions in their hosts, and several co-opted gag genes might be subject to positive selection. Taken together, our results provide a comprehensive picture of LTR retrotransposon gag gene co-option events that occurred during the deep evolution of eukaryotes, and suggest paucity of LTR retrotransposon gag gene co-option during the deep evolution of eukaryotes.

Studies suggesting that medicinal plants are not chosen at random are becoming more common. The goal of this work is to shed light on the role of botanical families in ethnobotany, depicting in a molecular phylogenetic frame the relationships between families and medicinal uses of vascular plants in several Catalan-speaking territories. The simple quantitative analyses for ailments categories and the construction of families and disorders matrix were carried out in this study. A Bayesian approach was used to estimate the over- and underused families in the medicinal flora. Phylogenetically informed analyses were carried out to identify lineages in which there is an overrepresentation of families in a given category of use, i.e., hot nodes. The ethnobotanicity index, at a specific level, was calculated and also adapted to the family level. Two diversity indices to measure the richness of reported taxa within each family were calculated. A total of 47,630 use reports were analysed. These uses are grouped in 120 botanical families. The ethnobotanicity index for this area is 14.44% and the ethnobotanicity index at the family level is 68.21%. The most-reported families are Lamiaceae and Asteraceae and the most reported troubles are disorders of the digestive and nutritional system. Based on the meta-analytic results, indicating hot nodes of useful plants at the phylogenetic level, specific ethnopharmacological research may be suggested, including a phytochemical approach of particularly interesting taxa.

Comparative Ethnobotany

Plants are important in traditional Inuit life. They are used for food, tea, medicine, etc. Based on semi-structured interviews with 35 informants, we documented and compared plant names and uses in Kangiqsualujjuaq, Nunavik, and in Nain, Nunatsiavut. Plant names and uses were expected to be similar between communities owing to common boreal–subarctic environments and cultural ties. Both communities reported the same number of taxa, with equivalent proportions of vascular and nonvascular plants, growth forms, use categories, and medicinal uses. Forty-three species were used in each community, for a total of 78 species from 39 families. Despite a high overlap in species distributions, only 35% of nonvascular and 56% of vascular species were used in both communities. Correspondence was higher at the family level (64% of nonvascular and 75% of vascular families shared). The Ericaceae family was the most used, followed by Rosaceae. Thirteen of 30 medicinal species were shared between communities. There was a low correspondence regarding the conditions for which the medicinal species were used. Edible taxa were shared the most (52%). Plant uses unique to either Nain or Kangiqsualujjuaq may reveal separate bodies of traditional knowledge, or may reflect an overall loss of ethnobotanical knowledge in the Subarctic due to recent lifestyle changes.

History Of

Previous analyses of the history of Phanerozoic marine biodiversity suggested that the post-Paleozoic increase observed at the family level and below was caused, in part, by an increase in global provinciality associated with the breakup of Pangea. Efforts to characterize the Phanerozoic history of provinciality, however, have been compromised by interval-to-interval variations in the methods and standards used by researchers to calibrate the number of provinces. With the development of comprehensive, occurrence-based data repositories such as the Paleobiology Database (PaleoDB), it is now possible to analyze directly the degree of global compositional disparity as a function of geographic distance (geo-disparity) and changes thereof throughout the history of marine animal life. Here, we present a protocol for assessing the Phanerozoic history of geo-disparity, and we apply it to stratigraphic bins arrayed throughout the Phanerozoic for which data were accessed from the PaleoDB. Our analyses provide no indication of a secular Phanerozoic increase in geo-disparity. Furthermore, fundamental characteristics of geo-disparity may have changed from era to era in concert with changes to marine venues, although these patterns will require further scrutiny in future investigations.

Abstract The problem of drug addiction for individuals, especially young people, is one of the most dangerous pests that cause many problems in various health, social and psychological aspects facing every society, but rather the whole world. The phenomenon of drug addiction often leaves individuals with dangerous negative effects on their behavior, whether towards themselves or towards others, and this requires the relevant institutions to strive for important and constructive solutions to reform such individuals, and then rid them of their negative behaviors, rehabilitate them and integrate them into society, to become active and effective individuals through their adoption of positive behaviors that are acceptable in line with the values, customs and traditions of their societies to which they belong. Therefore, our current study came to shed light on the most important effects resulting from the phenomenon of drug addiction among individuals through achieving the two research objectives which seek to know: 1- Causes of addiction to drug use among individuals 2- The effect of drug abuse on society. Upon verifying the two research objectives by relying on the analytical method of literature and previous studies, the two researchers reached the following results: First - The most important causes of youth addiction to drugs are poverty, begging, loss of one or both parents, the presence of a criminal in his family, invalid education and other various phenomena and deviations. Second - The symptoms of drug addiction push the addicted person to adopt deviant behaviors, as well as afflicting the addicted individual to psychological and mental pressures, and then afflicting his family with chronic diseases, in addition to the family breakdown occurring in the homes of drug addicts. Key words: drugs; Drug effect; The individual and society.

The street child that is driven by circumstances to live outside the supportive structure of the family, is on his own. He doesn’t have the educational developmental opportunities that children who grow up in families and societies do. He finds himself in a unique educational and living environment. From an educational psychologist’s point of view, this environment is abnormal. It is therefore a great challenge for the educational psychologist to try and avoid or resolve negative effects of the child's living environment. An exploratory-, descriptive-, contextual- and qualitative study was done, with the aim of gaining insight and understanding into the life of the street child in Hillbrow as well as his experiences of his situation. The results obtained from the interviews were placed in four categories. These categories are: The street child’s continuous struggle to survive, his need for a “normal child life” , his inability to accept responsibility and the presence of a normative awareness within the street child. In conclusion it is clear that the experiential world of the street child is multi-facetted. In general it appears that the street child has many limitations and difficulties which he experiences, and that input by an educational psychologist can have meaningful influence in his life.

The macroscopic and microscopic characters of dorsal guard hairs of Indian lagomorphs (four species of pikas and three species of hare) are described; the cuticular and medullary characters are similar between the species studied.  The cuticular and medullary characters, however, are dissimilar between the family Ochotonidae and Leporidae.  The cross-section of hair of the species had shown two identical shapes between the family Ochotonidae and Leporidae.  The cross-section was observed as an oval shape in all the four ochotonid species, whereas there was a dumb-bell shape in all three leporid species.  The hair of the Indian lagomorphs can easily be differentiated up to the family level on the basis of their unique cuticula, medulla and cross-section of the dorsal guard hair.  The high-resolution microphotographs and key characteristics of hair that are presented here can be used as an appropriate reference for family-level identification of Indian lagomorphs.

King Uros (1243-1276) erected the Church of the Holy Trinity in the Sopocani monastery in about 1270 and, in it, he prepared tombs for the first hegoumenos of Sopocani, his mother Queen Ana, for himself and the then archbishop, Joanikije (Fig. 1). Over each tomb there is a marble sarcophagus surrounded by appropriate wall paintings. The tombs of Uros and Joanikije were located in the western bay of the naos. Thus, the recently announced hypothesis, that the endowed did not intend to be buried in Sopocani, is unfounded. The intention of King Uros was only brought into question in 1276 when he was driven from the throne by his older son, Dragutin. The overthrow caused a major drama in the family, the state and the Church. King Uros retired to the southern part of the state (Hum), where he became a monk and subsequently died (perhaps in 1277). His wife Jelena received vast territories from her son, the new king, which she practically ruled independently, while Archbishop Joanikije, after having denied Dragutin his blessing, retired with the former king and died in the region of Pilot in 1279. King Dragutin (1276-1282) made a great effort to mitigate the negative effects of the overthrow: he continued his father's foreign policy established good relations with neighboring Dubrovnik, took pains to appease his mother, Queen Jelena, by granting her vast territories, and to win the support of the Church by erecting, repairing or presenting gifts to several churches and monasteries. He certainly obtained the Sopocani monastery through hereditary ktetorial rights.
