Zooplankton biodiversity and community structure vary along spatiotemporal environmental gradients in restored peridunal ponds
2015
<p>Zooplankton assemblages in neighboring ponds can show important spatial and temporal heterogeneity. Disentangling the influence of regional versus local factors, and of deterministic versus stochastic processes has been recently highlighted in the context of the metacommunity theory. In this study, we determined patterns of temporal and spatial variation in zooplankton diversity along one hydrological year in restored ponds of different hydroperiod and age. The following hypotheses regarding the assembling of species over time were tested: i) dispersal is not limited in our study system due to its small area and high exposure to dispersal vectors; ii) community dissimilarity among …
Gentrifizierung in periurbanen Räumen Frankreichs: Am Beispiel des Umlandes von Nancy
2019
International audience; Gentrifizierungsprozesse in periurbanen Räumen Frankreichs fanden in der Forschung bisher kaum Beachtung; sie wurden als naheliegende Prozesse in Kernstädten verstanden und untersucht. Zudem wurde eher die Krise der Vorstädte, der banlieues beachtet, womit Stigmatisierung und Ausgrenzung analyseleitend wurden. Im vorliegenden Beitrag wird nun hingegen am Beispiel des Umlandes der Metropole Nancy (Region Grand Est) Gentrifizierung als Entwicklung herausgestellt, die sich ebenfalls als konstitutiv für periurbane Räume und damit kleinere Umlandgemeinden von Städten bzw. insbesondere Metropolen andeutet. Vor dem Hintergrund einer Beleuchtung bisheriger Forschungszugänge …
Where do the highly educated migrate? Micro-level evidence from finland
2003
This paper analyses the role which migration of highly educated labour plays in human capital reallocation. The study focuses on actual migrants, examining the direct effect of educational attainment on destination choices. The paper uses the ordered probability model and a micro-level data set in econometric analyses. Individual level investigations of migrants show that highly educated migrants are likely to move to urban regions. As a result, the reallocation of highly educated labour, and thereby also the redistribution of human capital, seems to be taking place in Finland. peerReviewed
Towards understanding the epidemiology of Neisseria meningitidis in the African meningitis belt: a multi-disciplinary overview
2016
International audience; Objectives: Neisseria meningitidis is the major cause of seasonal meningitis epidemics in the African meningitis belt. In the changing context of a reduction in incidence of serogroup A and an increase in incidence of serogroups W and C and of Streptococcus pneumoniae, a better understanding of the determinants driving the disease transmission dynamics remains crucial to improving bacterial meningitis control.Methods: The literature was searched to provide a multi-disciplinary overview of the determinants of meningitis transmission dynamics in the African meningitis belt.Results: Seasonal hyperendemicity is likely predominantly caused by increased invasion rates, spo…
Redistribution of tax resources: a cooperative game theory approach
2021
AbstractWe consider the problem of how to distribute public expenditure among the different regions of an economic entity after all taxes have been collected. Typical examples are: the regions that make up a country, the states of a federal country, or the countries of a confederation of countries. We model the problem as a cooperative game in coalitional form, called the tax game. This game estimates the fiscal resources collected in each region, or coalition of regions, by differentiating between what comes from economic activity within each region and what comes from trade with the other regions. This methodology provides a measure of the disagreement within a region, or coalitions of re…
Religion and the Scandinavian Welfare State: Public Support for Socio-economic Rights in Times of Migration
2020
The theme of this article is the legitimisation of social and economic rights within the context of the Scandinavian welfare state. This problem has become more prominent in the light of the recent influx of immigrants from countries in the Middle East and Africa dominated by other religious and cultural traditions than Lutheran Protestantism. Two questions are discussed in the article. First, what role has religion played vis-a-vis the development of the welfare states in Scandinavia? Second, in what ways have recent immigration trends influenced popular support for welfare provision and social rights?
Mitochondrial DNA in the central european population
2000
Sequencing of mtDNA is an advanced method for the individualisation of traces. Disadvantages of this method are expensive and time-consuming analysis and evaluation procedures as well as the necessary stock of population-genetic data which is still insufficient. Central European institutes of forensic medicine from Germany, Austria, and Switzerland have been working together since the beginning of 1998 to establish a mtDNA database. The aim is to build up a large stock of forensically established data and provide population-genetic data for frequency investigations, which will serve as a basis for expert opinions and scientific research. Good data quality is ensured by using original sequen…
New Insights Into Mitochondrial DNA Reconstruction and Variant Detection in Ancient Samples
2021
Ancient DNA (aDNA) studies are frequently focused on the analysis of the mitochondrial DNA (mtDNA), which is much more abundant than the nuclear genome, hence can be better retrieved from ancient remains. However, postmortem DNA damage and contamination make the data analysis difficult because of DNA fragmentation and nucleotide alterations. In this regard, the assessment of the heteroplasmic fraction in ancient mtDNA has always been considered an unachievable goal due to the complexity in distinguishing true endogenous variants from artifacts. We implemented and applied a computational pipeline for mtDNA analysis to a dataset of 30 ancient human samples from an Iron Age necropolis in Poliz…
Analisi paleogenetica dei cacciatori-raccoglitori della Sicilia: nuovi dati sul primo popolamento dell’isola
2022
The first undisputed colonization of the island has been linked to Late or Final Epigravettian groups after the Last Glacial Maximum (LGM), as evidenced by the fossil record. Two significant sites to investigate this issue are the Grotta di San Teodoro (Acquedolci, Messina) and the Grotta d’Oriente (Favignana island). The Grotta di San Teodoro has yielded the oldest and largest human skeletal sample yet found in Sicily. Inside the cave, during field excavations carried out in the 1937-1947 years, seven human adults have been discovered (ST1-ST7). In the Grotta d’Oriente four prehistoric burials assigned to Late Upper Paleolithic (Oriente A and C) and Mesolithic (Oriente B and X) were uneart…
