Genomic diversity and population structure analysis reveal few genetic differences among Ethiopian indigenous sheep populations
2017
African sheep, like other domestic sheep, are domesticated from the Asiatic mouflon (Ovis orientalis). They entered the continent through the North and the Horn of Africa regions following maritime and terrestrial trading routes. Ethiopia is one of the main entry points of various plant and animal domesticates into Africa. It is characterised by diverse agro-ecologies, ancient human ethnic diversity and the presence of indigenous sheep breeds/populations of unprecedented morphological diversity (e.g. tail types). Here, we investigate the genome diversity and population structure of 146 unrelated animals from 11 Ethiopian indigenous sheep populations. DNA was extracted from ear tissue punche…
"I felt like a lonely person in the desert" : a case study on factors moderating interunit communication in multinational headquarters-subsidiary rel…
2017
One of the biggest challenges for internationalizing businesses is to develop and maintain efficient internal communication processes across national and cultural borders. This thesis aims to examine what are the most important organizational structures and communicational practices for a successful multinational headquarters-subsidiary relationship, and what do the communicational practices, such as the mechanics of language use and interunit knowledge-transfer, imply about the efficiency of global co-operation. This study considers the experiences of one case company’s Finnish headquarters and Dutch subsidiary on internal communication in a crucial phase of internationalization. The data …
Disentangling directional and fluctuating asymmetry in a genome-wide association study.
2018
8 pages; International audience; Although directional and fluctuating asymmetry have been frequently assessed independently, they are indeed associated concepts both in theory and in practice. However, they can be difficult to disentangle in genome-wide association studies, where the appropriate shape statistics are not fully developed. Although the usage of Procrustes distances to overcome this problem may be tempting, this does not reliably help to identify the underlying genetic components of directional and fluctuating asymmetries. Here, similarities and differences among different approaches have revealed that the genetic component of the skull asymmetry in this population of mice is m…
Percorsi della devianza e della diversità. Dall'"uomo atavico" al "senza permesso di soggiorno"
2007
Il volume, oltre a tracciare l’evoluzione dei concetti riconducibili all’ampia fenomenologia delle condotte devianti, ne rintraccia ed evidenzia i processi culturali e sociali che vi fanno da sfondo. Costituendosi come un articolata ed approfondita riflessione sulle teorie dell'agire sociale e sui i modi con cui si determinano le relazioni, il volume si sofferma sulle strategie argomentative e i processi interpretativi con cui i “devianti” – gli stranieri, i “senza fissa dimora”, i “diversi”, i “disoccupati” – costituendo proiettivamente una minaccia all’ordine sociale, sono stati nel tempo individuati, etichettati ed emarginati dalle istituzioni. Ogni capitolo è correlato, oltre che da una…
Ethnicity, 2013/8 : Ethnic Diversity and Ethnic Studies
2013
"Ethnicity" – a peer-reviewed journal was established by the Institute of Philosophy and Sociology (University of Latvia). The journal publishes original works about ethnicity in different fields of knowledge – sociology, history, social linguistics, social psychology, law, political science.
Análisis conjunto y espacios naturales: una aplicación al Paraje Natural del Desert de les Palmes
2007
We use stated preference methods to analyze consumer preferences on the attributes of protected natural areas and to estimate the willingness to pay for reducing the risk of fires in the site. For the first goal, conjoint analysis is used. Three attributes are considered: biodiversity, dimension of the natural area and the economic contribution that would have to be made for its maintenance and preservation. The willingness to pay for reducing the risk of fires has been estimated using choice experiment. The data have been gathered from a mail survey conducted among people living near the Desert de les Palmes Park, a protected area located in the Valencian Community (Spain). En el trabajo s…
Database Species-Area Relationships in Palaearctic Grasslands
2012
The Database Species-Area Relationships in Palaearctic Grasslands (GIVD ID EU-00-003) is an initiative of the European Dry Grassland Group (EDGG) and primarily functions as repository for all data sampled during the EDGG Research Expeditions. During these expeditions two types of highly standardised sampling of dry grassland vegetation in the Palaearctic realm are carried out: (i) nested-plot sampling on squares of 0.0001, 0.001, 0.01, 0.1, 1, 10, and 100 m2; (ii) additional normal releves of 10-m2 plots. For all plot sizes, the terricolous vascular plants, bryophytes, and lichens are recorded that are superficially present (shoot presence). Additionally, for all 10-m2 plots species cover i…
Effective Practices in Mitigating Soil Erosion from Fields
2017
Soil erosion by water is a natural process that cannot be avoided. Soil erosion depends on many factors, and a distinction should be made between humanly unchangeable (e.g., rainfall) and modifiable (e.g., length of the field) soil erosion factors. Soil erosion has both on-site and off-site effects. Soil conservation tries to combine modifiable factors so as to maintain erosion in an area of interest to an acceptable level. Strategies to control soil erosion have to be adapted to the desired land use. Knowledge of soil loss tolerance, T, i.e., the maximum admissible erosion from a given field, allows technicians or farmers to establish whether soil conservation practices need to be applied …
Land use effects on bacterial diversity in Mediterranean soils vulnerable to desertification
2021
The soil microbiota is recognized as key player in both diversity and productivity of terrestrial ecosystems and it is mandatory to include its role in soil quality evaluation. The bacterial communities in soils vulnerable to desertification can undergo perturbations by various human activities, such as unsustainable land use and management, and by climate change. Alteration in microbial diversity and composition are sentinels of the impact of environmental changes on soil quality. Within the LIFE Desert-Adapt project we analyze the soil bacterial diversity and composition across European Soils threatened by desertification in the southern Mediterranean regions (Italy, Spain and Portugal) a…
A soil biodiversity survey coupled with the national soil quality monitoring network?
2021
International audience; Despite its importance for human activities, soil biodiversity remains largely unknown and threatened. Aware of the need for large-scale monitoring, we studied the feasibility to add a soil biodiversity survey (RMBS-Biodiversity) to the already existing French soil quality monitoring network (RMQS). We worked with soil biodiversity experts to couple RMBS-Biodiversity with RMQS i.e. to choose soil taxons and functions, the methodologies and the sampling design. According to the experts, the sampling design of RMQS fits with a soil biodiversitysurvey. We propose sampling protocols for i) bacteria and fungi, ii) protists, iii) nematodes, iv) mesofauna (particularly spri…
