This study aimed at determining the population genetic structure of Mediterranean fruit flies (Ceratitis capitata) in North-eastern Brazil, so as to improve our understanding of the viability of the inter-simple sequences repeat (ISSR) markers in Brazilian populations, along with inferences on population genetic composition which can be used in management programs. For this, ISSR markers were used in groups collected from four municipalities in this region. Primers were polymorphic, revealing moderate expected heterozigosity, with 80% of the variation occurring within populations and moderate structure. Bayesian analysis revealed K = 3, consistent with pairwise FST and indicating low structure between Barra do Choça and Planalto, and moderate structure between Caraíbas and Planalto. Data indicated high diversity, suggesting two interpretations: the analyzed populations arose from a single population and are now under structuring processes, or populations had different origins, but are currently connected by gene flow. Thus, ISSR primers were affective in obtaining information about genetic structure of C. capitata populations in North-eastern Brazil, as evidenced by high polymorphism and separation or grouping of populations according to their allelic compositions. Furthermore, this paper provides useful information for understanding the genetic diversity, population structure and gene flow of C. capitata populations in this region and developing regional strategies for the control and management of the species.

Changes in what anthropologists understand “clan” to refer to, and the social relations that many sociologists think of as constituting a “nuclear family” are at the centre of this article. It is based on ethnography among Wampar speakers in north-eastern Papua New Guinea (PNG). Among the Wampar, different, sometimes conflicting, transitions relevant to the emergence of the family as an accentuated social entity can be observed; yet all are a result of Christianisation and the local effects of capitalism. Nominally patrilineal clans (sagaseg), after a period when they seemed to have a somewhat diminished social significance, are again crucial social units: a result of the government’s requirement that statutory Incorporated Land Groups (ILGs) form the sole legal basis of compensation for land use. At the same time, there has been an increasing emphasis on the nuclear family, which, along with the aspiration for modern lifestyles (and their associated consumption patterns) and education for children, has reconfigured the gendered division of labour. Ideals of companionate marriage and values specific to the nuclear family have become much more critical to social practices. In some families, traditional notions of descent have lost importance to such an extent that some young people are no longer aware of their sagaseg membership. Wampar men and women discuss these conflicting tendencies and argue about the different values that ground them. Which argument prevails often depends on the specific position of the person confronting them.

A new species of the genus Ocnogyna Graslin, [1837], O. mooseri sp. n. is described from north-eastern Libya. The female of the new species is fully winged but differs from all known species groups of Ocnogyna in a number of diagnostic features and is also externally reminiscent of Tajigyna gansoni Dubatolov, 1990 endemic to Tajikistan. The diagnostic comparison is made with the North African Ocnogyna advena (Fabricius, 1787) having externally similar males but brachypterous females and to the externally dissimilar Ocnogyna parasita (Hübner, 1790) species group having the most similar female genitalia structures.

The subjective well-being of children in residential care is a relevant issue given the practical implications for improving the lives of these children who live in contexts of vulnerability. The question addressed in this respect was: “How does this well-being change over the years”? Thus, the aim of this study was to compare the subjective well-being displayed by adolescents aged 11–14 in residential care in Catalonia (north-eastern Spain) in 2014 to that displayed by adolescents in residential care in 2020. To this end, 572 responses to a questionnaire adapted from the Children’s Worlds project (364 from 2014 and 208 from 2020) were analysed with respect to the life satisfaction items. In both 2014 and 2020, the questionnaires had the same wording, and data were disaggregated by gender. No significant differences in means were observed between most of the life satisfaction items in 2014 and 2020, with the exception of satisfaction with friends and classmates and the area where you live, with lower means for these items in 2020. There is a discussion of the possible influence of COVID-19 on these results, while the overall stability of these children’s subjective well-being over the years is highlighted.

Abstract. Recently, a significant increase in the atmospheric moisture content has been documented over the Arctic, where both local contributions and poleward moisture transport from lower latitudes can play a role. This study focuses on the anomalous moisture transport events confined to long and narrow corridors, known as atmospheric rivers (ARs), which are expected to have a strong influence on Arctic moisture amounts, precipitation, and the energy budget. During two concerted intensive measurement campaigns – Arctic CLoud Observations Using airborne measurements during polar Day (ACLOUD) and the Physical feedbacks of Arctic planetary boundary layer, Sea ice, Cloud and AerosoL (PASCAL) – that took place at and near Svalbard, three high-water-vapour-transport events were identified as ARs, based on two tracking algorithms: the 30 May event, the 6 June event, and the 9 June 2017 event. We explore the temporal and spatial evolution of the events identified as ARs and the associated precipitation patterns in detail using measurements from the French (Polar Institute Paul Emile Victor) and German (Alfred Wegener Institute for Polar and Marine Research) Arctic Research Base (AWIPEV) in Ny-Ålesund, satellite-borne measurements, several reanalysis products (the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) Interim (ERA-Interim); the ERA5 reanalysis; the Modern-Era Retrospective analysis for Research and Applications, version 2 (MERRA-2); the Climate Forecast System version 2 (CFSv2); and the Japanese 55-Year Reanalysis (JRA-55)), and the HIRHAM regional climate model version 5 (HIRHAM5). Results show that the tracking algorithms detected the events differently, which is partly due to differences in the spatial and temporal resolution as well as differences in the criteria used in the tracking algorithms. The first event extended from western Siberia to Svalbard, caused mixed-phase precipitation, and was associated with a retreat of the sea-ice edge. The second event, 1 week later, had a similar trajectory, and most precipitation occurred as rain, although mixed-phase precipitation or only snowfall occurred in some areas, mainly over the coast of north-eastern Greenland and the north-east of Iceland, and no differences were noted in the sea-ice edge. The third event showed a different pathway extending from the north-eastern Atlantic towards Greenland before turning south-eastward and reaching Svalbard. This last AR caused high precipitation amounts on the east coast of Greenland in the form of rain and snow and showed no precipitation in the Svalbard region. The vertical profiles of specific humidity show layers of enhanced moisture that were concurrent with dry layers during the first two events and that were not captured by all of the reanalysis datasets, whereas the HIRHAM5 model misrepresented humidity at all vertical levels. There was an increase in wind speed with height during the first and last events, whereas there were no major changes in the wind speed during the second event. The accuracy of the representation of wind speed by the reanalyses and the model depended on the event. The objective of this paper was to build knowledge from detailed AR case studies, with the purpose of performing long-term analysis. Thus, we adapted a regional AR detection algorithm to the Arctic and analysed how well it identified ARs, we used different datasets (observational, reanalyses, and model) and identified the most suitable dataset, and we analysed the evolution of the ARs and their impacts in terms of precipitation. This study shows the importance of the Atlantic and Siberian pathways of ARs during spring and beginning of summer in the Arctic; the significance of the AR-associated strong heat increase, moisture increase, and precipitation phase transition; and the requirement for high-spatio-temporal-resolution datasets when studying these intense short-duration events.
