The common dogwood (Cornus sanguinea L., Cornaceae) across the European continent represents a species with validated ornamental and nutraceutical value that has been utilized by humans for thousands of years but has been abandoned during modern times. It still represents however, a valuable but neglected native germplasm resource. The development...

The snowy Mespilus, or serviceberry (Amelanchier ovalis Medik., Rosaceae) represents a neglected and underutilized small fruit tree species with high nutritional value. In this work, we present the results of a long-term study facilitating the sustainable exploitation of A. ovalis as a new germplasm resource from the Greek flora. Ten wild-growing p...

The landscape in Greek mountains has changed dramatically during the last decades mainly due to abandonment of past land uses . In the context of the research project “Ecotime Machine - Application development for 4D tour in landscape history”, we investigated the landscape history of South-East Gramos mountain, through a combination of different m...

Wild-growing Cornelian cherries (Cornus mas L., Cornaceae) are well-known native fruits in Greece since ancient times that are still consumed locally nowadays. Modern research has highlighted the value of Cornelian cherries as functional food with exceptional health benefits on account of the fruits’ biochemical profile. However, apart from local c...

In the context of sustainable utilisation of valuable but neglected plant resources, a multifaceted study is presented herein for Greek native genotypes of elderberry (Sambucus nigra L., Caprifoliaceae), a species with an appreciated pharmaceutical and nutritional value. At the first phase, fresh plant materials (leaves, softwood cuttings) were col...

Dogroses belong to a taxonomically difficult genus and family and represent important phytogenetic resources associated with high ornamental, pharmaceutical-cosmetic and nutritional values, thus suggesting a potentially high exploitation merit. Triggered by these prospects, wild-growing Rosa canina populations of Greece were selected for investigat...

In the context of the project “Ecotime Machine - Application development for 4D tour in landscape history”, we investigated the vegetation history of South-East Grammos mountain, through the photointerpretation of 3 successive aerial photos series (1945, 1970, 2015), vegetation samplings and review of data collected by previous Forest Management Pl...

During the research project “Ecotime Machine - Application development for 4D tour in landscape history”, we investigated the vegetation history of South-East Gramos mountain, through the photointerpretation of 3 successive aerial photos series (1945, 1970, 2015), in combination with other methods. Results prove an important increase of forest area...

Agroforestry and small-scale traditional farming systems as well as multi- functional forest landscapes survived in many rural areas in Europe (both in mountains and islands) that escaped the large scale agricultural transformation that has been supported by the EU Common Agricultural Policy (CAP). How can we build a more resilient rural economy in...

Greek mountains have a rich landscape history, hosting for centuries dynamic communities and productive activities. Through 20th century, these activities are gradually abandoned. Consequently, forest ecosystems succeed agricultural and pastoral land. The prominence of this landscape history, beyond historical and scientific interest, may work as a...

Within the scope of the POPULISMUS research project (2014–5), we have engaged in a methodological cross-fertilization between Essex School-inspired methods of analysis and computer-assisted text analysis (drawing on corpus linguistics). In this chapter, emphasis is placed on the Greek case and the material analyzed involves newspaper articles from...

This article focuses on two issues involved in the formation and political trajectory of populist representations within political antagonism. First, it explores the role of crisis in the articulation of populist discourse. This problematic is far from new within theories of populism but has recently taken a new turn. We thus purport to reconsider...

Revisiting the trend of identifying populism with extreme right parties, in this paper we aim to problematize such associations within the context of today’s Europe. Drawing on examples from relevant parties in France and the Netherlands, and applying a discourse-theoretical methodology, we test the hypothesis that such parties are better categoriz...

Critical engagement with the case of Chavismo in Venezuela can offer valuable insights for a fuller understanding of contemporary populism in Latin America. While for some scholars Chávez's populism has fostered popular empowerment, others dwell on the newly confirmed tensions between populism, liberal rights, and democratic proceduralism. This art...

A united and peaceful Europe seemed a distant dream for the generation that went through the experience of war and destruction in the first half of the 20 th century. In the latter part of that century, this hope did eventually gain shape and reality in the European Union. Despite its official proclamation of peace, social well being, and an altern...

The representation of a complex but stable, self-regulated and, finally, harmonious nature penetrates the whole history of Ecology, thus contradicting the core of the Darwinian evolution. Originated in the pre-Darwinian Natural History, this representation defined theoretically the various schools of early ecology and, in the context of the cyberne...

The conflicts around the scientific status of the concept of diversity are considered here as symptoms of hidden, socially originated, ideological representations inherent in the theoretical context of western ecology. Species diversity was coined in the 1940s, as a constant in the statistical models that described the distribution of individuals i...
