The interaction between road network and natural landscape type
(2007)The construction of new road infrastructure can impact on landform in a number of ways. The type of natural landscape and the terrain or topographical features of the land determines where roads can go and therefore strongly ... -
Interconnectivity vs. isolation of prokaryotic communities in European deep-sea mud volcanoes
(2013)During the past two decades, European cold seep ecosystems have attracted the scientific interest and to date there are several studies which have investigated the community structure and biodiversity of individual sites. ... -
Intraspecific genetic variation of striped red mullet (Mullus surmuletus L.) in the Mediterranean Sea assessed by allozyme and random amplified polymorphic DNA (RAPD) analysis
(1999)Allozyme analysis on 20 putative enzyme-coding loci and RAPD analysis on 154 markers, amplified by eight decamer random primers, were used to assess the genetic variation of striped red mullet, Mullus surmuletus L., collected ... -
The invasion route for an insect pest species: the tobacco aphid in the New World
(2010)Biological invasions are rapid evolutionary events in which populations are usually subject to a founder event during introduction followed by rapid adaptation to the new environment. Molecular tools and Bayesian approaches ... -
Investigation of factors affecting the trophic state of a shallow Mediterranean reconstructed lake
(2017)In this article, we focus on shallow sub-tropical lakes and study the factors that determine their trophic state and food web structure. We use the model PCLake to simulate lake nutrient dynamics and investigate key factors ... -
Land spreading of wastewaters from the fruit-packaging industry and potential effects on soil microbes: Effects of the antioxidant ethoxyquin and its metabolites on ammonia oxidizers
(2016)Thiabendazole (TBZ), imazalil (IMZ), ortho-phenylphenol (OPP), diphenylamine (DPA), and ethoxyquin (EQ) are used in fruitpackaging plants (FPP) with the stipulation that wastewaters produced by their application would be ... -
Landscape protection and management in Greece: Problems, perspectives, and policies
(2003)An assessment of all actors involved to make suggestions for the establishment of the adequate bodies, services and mechanisms that would help for a new landscape strategy and policy in Greece was presented. The renewal ... -
A learning progression should address regression: Insights from developing non-linear reasoning in ecology
(2016)Although ecological systems at varying scales involve non-linear interactions, learners insist thinking in a linear fashion when they deal with ecological phenomena. The overall objective of the present contribution was ... -
Major histocompatibility complex variation at class II DQA locus in the brown hare (Lepus europaeus)
(2009)The major histocompatability complex (MHC) is a multigene family of receptors that bind and present antigenic peptides to T-cells. Genes of the MHC are characterized by an outstanding genetic polymorphism, which is considered ... -
Mapping the optimal forest road network based on the multicriteria evaluation technique: the case study of Mediterranean Island of Thassos in Greece
(2015)The sustainable management of forest resources can only be achieved through a well-organized road network designed with the optimal spatial planning and the minimum environmental impacts. This paper describes the spatial ... -
Microsatellite and Wolbachia analysis in Rhagoletis cerasi natural populations: population structuring and multiple infections
(2014)Rhagoletis cerasi (Diptera: Tephritidae) is a major pest of sweet and sour cherries in Europe and parts of Asia. Despite its economic significance, there is a lack of studies on the genetic structure of R.cerasi populations. ... -
Mitochondrial DNA variation in northeast atlantic and mediterranean populations of norway lobster, Nephrops norvegicus
(2004)Analysis of the genetic structure of the Norway lobster (Nephrops norvegicus), a marine crustacean with high commercial value, was undertaken to gain information regarding the differentiation of Atlantic from Mediterranean ... -
Mitochondrial phylogeography of the European wild boar: the effect of climate on genetic diversity and spatial lineage sorting across Europe
(2014)Aim Climate changes in the past had a deep impact on the evolutionary history of many species and left genetic signatures that are often still detectable today. We investigated the geographical pattern of mitochondrial DNA ... -
Modeling and optimization of the smart grid ecosystem
(2016)The smart energy grid has evolved into a complex ecosystem, with new entering actors such as aggregators, and traditional ones like consumers, operators and generators having fundamentally different, active roles in the ... -
Modeling the effect of social factors on improving biodiversity protection
(2012)The aim of this study is to investigate the effect of social factors (expressed as social and institutional trust social norms, and social networks) on the decision of individuals to pay for improvement of environmental ... -
Molecular phylogenetic convergence within Elasmobranchii revealed by cytochrome oxidase subunits
(2015)The phylogenetic relationships within the subclass of Elasmobranchii are under question within the academic community and their systematic classification based on morphological, or physiological characteristics has not yet ... -
Oil consumption and economic efficiency: A comparative analysis of advanced, developing and emerging economies
(2011)This paper investigates the economic efficiency-oil consumption relationship in 42 countries during the period 1986-2006. In a first stage by using DEA window analysis countries' economic efficiencies are obtained. In a ... -
Phylogenetic relationships among four species of Mullidae (Perciformes) inferred from DNA sequences of mitochondrial cytochrome b and 16S rRNA genes
(2001)DNA sequence comparisons of two mitochondrial DNA genes were used to infer phylogenetic relationships among four species of mullids. Approximately 238 by of the mitochondrial 16S ribosomal RNA (rRNA) and 261 by of the ... -
Phylogeography of the brown hare (Lepus europaeus) in Europe: a legacy of south-eastern Mediterranean refugia?
(2009)We analysed the population genetics of the brown hare (Lepus europaeus) in order to test the hypothesis that this species migrated into central Europe from a number of late glacial refugia, including some in Asia Minor. ... -
Phylogeography of the rock partridge (Alectoris graeca)
(2003)We used mitochondrial DNA control-region and microsatellite data to infer the evolutionary history and past demographic changes in 332 rock partridges (Alectoris graeca ) sampled from throughout the species' distribution ...
