There is a growing demand for wild caught juvenile fish to supply the market for aquaculture. However, little is known about the genetic effects of juvenile collection from wild populations. There are a number of imminent threats to both aquaculture systems and wild fish populations. Juvenile collection from a single population can for example reduce population’s evolutionary potential as well as the disease resistance within an aquaculture pond. In this study, we investigated the local genetic structure of juvenile mullets collected from five sites around Bagamoyo (Tanzanian mainland) and Zanzibar Island, East Africa. Fish were caught in low tide using a seine net. The fish were morphologically identified, and then genetically identified using direct sequencing of the CO1 gene with cross referencing with the Barcode of Life Database (BOLD) systems.  Molecular variance analyses were used to infer genetic subdivision based on geographic sampling site as well as inferring population structure through the Bayesian assignment test implemented in STRUCTURE 2.3. Our results showed that samples morphologically identified as Mugil cephalus where in fact Valamugil buchanani and we also found evidence of an introgression genome event, where the gene flow from one species may have affected the general gene pool. The Bayesian analysis revealed a clear genetic population structure among the sampled fish; the main difference was the presence of a unique mainland cluster. Our findings may have important implications for management and conservation of mullet fishes in the region and elsewhere.

BACKGROUND: Animal migration requires adaptations in morphological, physiological and behavioural traits. Several of these traits have been shown to possess a strong heritable component in birds, but little is known about their genetic architecture. Here we used 454 sequencing of brain-derived transcriptomes from two differentially migrating subspecies of the willow warbler Phylloscopus trochilus to detect genes potentially underlying traits associated with migration.RESULTS: The transcriptome sequencing resulted in 1.8 million reads following filtering steps. Most of the reads (84%) were successfully mapped to the genome of the zebra finch Taeniopygia gutatta. The mapped reads were situated within at least 12,101 predicted zebra finch genes, with the greatest sequencing depth in exons. Reads that were mapped to intergenic regions were generally located close to predicted genes and possibly located in uncharacterized untranslated regions (UTRs). Out of 85,000 single nucleotide polymorphisms (SNPs) with a minimum sequencing depth of eight reads from each of two subspecies-specific pools, only 55 showed high differentiation, confirming previous studies showing that most of the genetic variation is shared between the subspecies. Validation of a subset of the most highly differentiated SNPs using Sanger sequencing demonstrated that several of them also were differentiated between an independent set of individuals of each subspecies. These SNPs were clustered in two chromosome regions that are likely to be influenced by divergent selection between the subspecies and that could potentially be associated with adaptations to their different migratory strategies.CONCLUSIONS: Our study represents the first large-scale sequencing analysis aiming at detecting genes underlying migratory phenotypes in birds and provides new candidates for genes potentially involved in migration.

The aim of this article is to suggest an explanatory set of factors to the popularity of gated housingin the Polish context. The explanation focuses on the divide between the public and the private sphere andencompasses economic, cultural and institutional explanations to the gating phenomenon. The empirical material consists of interviews, discourse analysis, a questionnaire, official reports and data, and legal regulation analysis. The Polish example display that both the remnants from the past and the contemporaryideals can be derived from the public-private divide. This divide has played a central role in the negotiationson urban space, the role of housing, and the identities and activities connected to housing and spatial issuessince 1989. It is argued that the introduction of market economy followed by socio-economic inequalities,has resulted in specific forms of creative strategies for individual actions among Poles and to the popularityof gated housing

The aim of this article is to examine the reasons behind the growing popularity ofgated communities in Poland by applying cultural, institutional and economic explanationsin the Polish context. The empirical material consists of interviews, newspaperarticles, legal acts concerning housing, official documents and a questionnaire. Thedivide between the public and private spheres is central to the explanatory model, andit is argued that it is this that has played a central role in the emergence and popularityof gated forms of housing in Poland. The introduction of a market economy and subsequentsocio-economic inequalities has resulted in specific forms of individual strategiesregarding housing preferences. It is suggested here that this specific form ofindividualism, connected with institutional shortcomings, cultural legacies and thepresent housing market, is reflected in the enclosed and private living spaces of today’s Poles.

This study examines how gender interplays with the news agenda during a very large scale event, in a country still undergoing political transition and where journalism plays a significant role in the nation-building process. The present study brings new knowledge to this area by examining the news agendas in South Africa on a specific gender-related issue: the rights of sex workers and trafficking victims, concerning men and children as well, but women in particular. This issue is often debated in connection with global sports events such as the World Cup. Drawing on interviews with media practitioners and on discourse analysis, the purpose of this study was to examine the news discourse on sex labour and trafficking and the connection with the 2010 FIFA World Cup. The findings suggest that the media discourse during the event was permeated with the rhetoric of nation-building. The combination of sport, media, and nationalism in a country in transition resulted in the ‘symbolic annihilation’ (Tuchman, 1978b) of a specific gender issue.

In this article we problematize our field roles as two linguistic ethnographers who aim to study the communication and documentation practices drawn upon by care workers in elderly care facilities in Sweden. Our field roles are discussed in relation to the complex nature of care workers’ knowledge and competence, which results from three different aspects of their work-identities: institutional, professional, and individual. As researchers, we found ourselves in constant dialogue with the research participants, and our field roles were continuously shaped and reshaped according to the individuals and the situations in which we became involved. Even aspects of our own identities taken into the field, such as our background and personal qualities, proved to be important in establishing good relations with the care staff. Coming closer to the participants’ professional identity proved to be of utmost importance for interpreting their choices and decisions in the workplace. Identity negotiation is presented here as a constructive way of discussing ethnographic field roles in the research field.

We report recent fieldwork on an early-16th-century wreck in the Stockholm archipelago, Sweden. The discovery not only provides new insights into early carvel shipbuilding and its adoption across northern Europe but manifests the changing role of ships and the nature of power and agency in the process of state formation at the dawn of the modern world.

Social movement activism requires emotional motivation and entails emotional costs, and, because of this, activists tend to be deeply involved in the management of emotions – or emotion work – and not just in connection with protest events, but also on an everyday basis. Based on a case study of animal rights activism in Sweden, this article identifies five types of emotion work that animal rights activists typically perform: containing, ventilation, ritualization, micro-shocking and normalization of guilt. The emotion work performed by activists, it is argued, is best understood from a moral-sociological perspective building on Durkheim’s sociology of morality, based on which the article then outlines key elements of a comprehensive theoretical framework for the study of emotion work in social movements.
