Social-ecological resilience (SER) expresses the capacity of a social-ecological system to adapt and transform. We investigated the ways in which different types and transformations of social capital influence the SER of a region. The study area, the Asteroussia Mountains in southern Crete, Greece, is a typical semiarid hilly/mountainous area of the eastern Mediterranean in which land degradation is one of the most important issues in land management, mostly related to overgrazing because of the growing size of the flocks of sheep and goats. The approach followed was qualitative, with in-depth interviews with a small number of key stakeholders in the area. The findings indicate many important changes in the area in terms of its production, economy, and...

Field measurements of coastal waves and currents in Portugal and Greece
Provedor de dados: 5
Autores: Paillard, Michel; Prevosto, Marc; Barstow, Sf; Soares, Cg.
The MAST II WAVEMOD Project aimed at improving stochastic modelling of ocean waves and currents in coastal waters. In order to supplement existing data, two measurement campaigns were carried our, one on the Atlantic coast of Portugal, and, secondly, on the northern coast of Crete in the Mediterranean. The Portuguese measurements covered 7 months during winter 1993-1994, while off Crete, measurements started early in February 1994 and continued for 10 months, In both sites, two directional Waveriders and one non-directional Waverider were deployed along a transect our from the coast in water depths between 10 and 100 m. In addition, the Mediterranean site also incorporated measurements of mean current velocities. Available satellite data were analysed to...

Répartition et organisation des foraminifères actuels dans le golfe de Kalloni (Grèce)
Provedor de dados: 5
Autores: Favry, A; Guelorget, O; Debenay, Jp; Lefebvre, A; Perthuisot, Jp.
As part of a global investigation of foraminifera importance in the Mediterranean paralic realm, the distribution of present foraminifera in Kalloni Bay was studied through species determination and counting. From these basic data, density, species richness, Shannon Index and dominance were calculated for several stations covering the whole basin. In addition, a factorial analysis of correspondances between stations and species assemblages was performed. All these methods concur in showing that the organization of foraminifera populations follows sc principal longitudinal gradient from the entrance towards the most continental reaches and a subsidiary transverse gradient. When compared with sedimentological data, the distribution of foraminifera does not...

On altitude dependent characters in Albinaria idaea (L. Pfeiffer, 1849), with a revision of the species (Gastropoda Pulmonata: Clausiliidae)
Provedor de dados: 16
Autores: Engelhard, G.H.; Slik, J.W.F.
Several forms of Albinaria idaea (L. Pfeiffer, 1849) have been described as (sub)species from various sites on Mt. Ida (Central Crete). In recent years, however, much additional material has been collected, which made clear that no sharp boundaries exist between these forms. Moreover, several characters proved to be altitude dependent to a certain extent. It may be concluded that on Mt. Ida only a single evolutionary entity can be distinguished, viz. A. i. idaea. On the isolated Mt. Kedros, south-west of Mt. Ida, an undescribed allopatric form was found, which because of its smaller size and differences in altitude dependent characters was given subspecific rank as A. i. amabilis ssp. nov. On the Paximadia Isles, south of Central Crete, a percostate and a...

Increased genetic diversity in Greek populations of the genus Ligidium (Crustacea: Isopoda: Oniscidea) revealed by RFLP analysis of mtDNA segments
Provedor de dados: 16
Autores: Klossa-Kilia, E.; Kilias, G.; Sfenthourakis, S.
We investigated mtDNA genetic differentiation and the phylogenetic relationships of 11 populations of the oniscidean genus Ligidium. We studied nine populations from Greece, assigned to three nominal species (L. euboicum, L. germanicum and L. beieri), and two from central Europe (L. germanicum and L. hypnorum), applying RFLP analysis of two mtDNA segments (12S rDNA and 16S rDNA) amplified by PCR. The analysis revealed seven monomorphic and four polymorphic populations, and 17 different haplotypes, each one present in one population only. Several restriction enzymes produced population specific patterns, enabling discrimination among the different populations. The estimated net nucleotide divergence between populations ranges from 1.06 to 16.52%, while the...

Beiträge zur Kenntnis der Pupillacea : XI. Speleodentorcula Beroni gen. &amp; spec. nov. (Mollusca: Gastropoda: Orculidae) Aus einer Höhle in Euboea, Griechenland
Provedor de dados: 16
Autores: Gittenberger, E.
A new troglobitic genus and species, viz. Speleodentorcula beroni gen. &amp; spec. nov., is described from the island of Euboea, Greece. The species, known from a single cave only, is quite isolated systematically. According to the structure of its shell and the genitalia S. beroni should be classified with the Orculidae. Within this family Speleodentorcula is most similar to Walklea anatomically; conchologically there is some vague resemblance to Fauxulus (apertural denticles) and Odontocyclas, Walklea, Fauxulus and Afriboysidia (surface sculpture). Speleodentorcula alone is considered the sister group of the taxon encompassing these last mentioned four genera.

On the only Greek Sphincterochila species, two Libyan close relatives, Cerigottella subgen. nov., and an extended diagnosis of the Sphincterochilidae (Mollusca, Gastropoda Pulmonata)
Provedor de dados: 16
Autores: Gittenberger, E.
From Greece, based on conchological characters, a single, endemic Sphincterochila species has been reported about a century ago. Its occurrence is still thought to be restricted to the islet of Andikithira. The structure of the genitalia, hitherto unknown, demonstrates that it concerns a separate species indeed; its closest relatives known are two Libyan species. These three species differ from the Sphincterochila species studied so far most clearly by the stimulatory organ, inserting not on the genital atrium but far more distally on the vagina. They are classified within Cerigottella subgen. nov.

Marine invertebrate diversity in Aristotle’s zoology
Provedor de dados: 16
Autores: Voultsiadou, E.; Vafidis, D.
The aim of this paper is to bring to light Aristotle’s knowledge of marine invertebrate diversity as this has been recorded in his works 25 centuries ago, and set it against current knowledge. The analysis of information derived from a thorough study of his zoological writings revealed 866 records related to animals currently classified as marine invertebrates. These records corresponded to 94 different animal names or descriptive phrases which were assigned to 85 current marine invertebrate taxa, mostly (58%) at the species level. A detailed, annotated catalogue of all marine anhaima (a = without, haima = blood) appearing in Aristotle’s zoological works was constructed and several older confusions were clarified. Some of Aristotle’s “genera” were found to...

Three species of the actinian genus Telmatactis Gravier, 1916, viz. T. forskalii (Ehrenberg, 1834), T. solidago (Duchassaing &amp; Michelotti, 1864) and T. cricoides (Duchassaing, 1850), occurring in Greece and the eastern Mediterranean, are described and discussed. Detailed data on the cnidom of the three species are provided. The characteristic penicilli of members of the genus Telmatactis are discussed. These penicilli were classified by Schmidt (1969, 1972) as p-rhabdoids (= penicilli) B1b, but it is here claimed that they actually belong in Schmidt's B2 group (provisionally as penicilli B2c).

Insectivores (Erinaceomorpha, Soricomorpha; Mammalia) from Karydia and Komotini (Thrace, Greece; MN 4/5)
Provedor de dados: 16
Autores: Doukas, C.S.; Hoek Ostende, L.W. van den.
The insectivores from the Thrace locality of Karydia (MN 4) are described, as well as an erinaceid molar from thenearby locality of Komotini (MN 5). The Karydia assemblagecontains the same genera of the Greek MN 4 localityAliveri, with the addition of a shrew and of Plesiosorex. An M2 of the latter is the southernmost occurrence of this genus, and the first record from the Mediterranean area. At the species level there are differences between Karydia and Aliveri. As Galerix kostakii n.sp. from Karydia is interpreted as a descendant of G. symeonidisi from Aliveri, a younger age for the Thrace locality, as was already assumed on the basis of the rodents, is confirmed. A model is proposed in which the symeondisi-kostakii lineage gives rise to Parasorex, of...

Autores: Willemse, F.; Helversen, O. von; Odé, B.
This paper presents a summary of the current knowledge on the systematics of the Greek taxa of Chorthippus, morphologically characterised by angled lateral pronotal keels (usually grouped as Glyptobothrus). Prior to this paper, based on traditional morphology, ten taxa of Chorthippus with angled lateral pronotal keels were recognized from Greece. Based on morphology as well as (and more importantly so) bioacoustics thirteen Greek taxa are now recognised. With addition of a few additional related taxa that occur only outside Greece, all are treated in this paper: Chorthippus apricarius apricarius (Linnaeus, 1758), C. vagans vagans (Eversmann, 1848) (not in Greece), C. v. cypriotus (Uvarov, 1936) stat. nov.

Development and Prospects of the Greek Cooperative Credit System
Provedor de dados: 31
Autores: Karafolas,   Simeon.
The credit cooperative system was established in Greece in 1993, following the creation of the appropriate legislative framework. The Greek system distinguishes two types of institutions: the cooperative bank that functions as a bank and the credit cooperative that cannot provide banking services. The Greek cooperative system is characterized by the autonomous and nonhomogenous development of the cooperative banks and credit cooperatives. Moreover, in 2001 the cooperative banks created a central nation-wide bank that has since helped the further development of the credit cooperative system. However and despite the large number of geographic departments involved in the credit cooperative system, the expansion of cooperative banks in the Greek bank market is...

Wine Roads in Greece: A Cooperation for the Development of Local Tourism in Rural Areas
Provedor de dados: 31
Autores: Karafolas,   Simeon.
An association of Wine Roads was developed in Greece at the beginning of the 1990s in an attempt to boost rural tourism. The association was created by wine producers in the regions of Macedonia and was then extended to Epirus, Thessaly and Thrace. Its main purpose has been the promotion of wine companies and the association's regional members, while its specific targets have been the development of local tourism, the support of cultural heritage and the improvement of product quality and related services. The Wine Roads initiative has received substantial financial support from the European Union and the State of Greece, mainly through the LEADER II program. However, socioeconomic results for the participating companies and regions appear to differ. An...

The contribution of innovations in total factor productivity of organic olive enterprises
Provedor de dados: 31
Autores: Karafillis,   C.C.; Papanagiotou,   Evangelos.
This paper measures the contribution of innovations in total factor productivity(TFP) of organic olive farmers. By constructing an innovation variable instead of the use of a time trend, technical change is replaced by technical difference and TFP growth becomes TFP difference. Primary cross section data on organic olive enterprises from a Greek region is used in the application of the restricted frontier profit function. Farmers are classified into groups according to their innovative ‘profile’. TFP difference among consecutive innovation groups is decomposed into technical difference and adjustment in innovativeness effects. Furthermore, efficiency differences among innovation groups are estimated. Results indicate that more innovative farmers perform...

ADULT EQUIVALENT SCALES REVISITED
Provedor de dados: 31
Autores: Demoussis,   Michael; Mihalopoulos,   Vassilis.
Use of the Tobit model for estimation of adult equivalent scale (AES) parameters and expenditure equations presupposes that zero observations represent exclusively corner solutions.  This paper tests for the underlying causes of zero observations and estimates accordingly the AES parameters, the household size in adult equivalents and the resulting expenditure equations and consumption profiles.  The empirical application concerns Greek household "soft" and "hard" cheese consumption.  The statistical results indicate that for the examined cheese categories the "double hurdle participation" model adjusted for non-normality and heteroskedasticity is the appropriate model for the estimation of AES parameters and expenditure equations.

Structural equation model (LISREL 8) was applied to test the causal relationships between tourist travel motivations and tourist destination. A survey containing Likert scale questions was conducted to collect data from 100 tourists who had travelled to Greece’s tourist destination. With the help of factor analysis, four dimensions were identified for scales used in the study: travel cost satisfaction, tourism product, tourism product attributes, and tourism product management. Results indicated that the travel cost satisfaction of tourists has a positive influence on tourism product, tourism product attributes and tourism product management. Moreover, our results suggested that the tourist demographics has a positive influence on tourism product and...

The present paper presents a two stage research which aims to depict the motivations and cognitive structures of quality food consumers through the use of Means–End Chain (MEC) approach and laddering technique. Quality food entails both organic and local protected/traditional products. The first stage of the research involved a meta-analysis of published journal articles regarding the purported motivations and cognitive structures of consumers when purchasing quality food. The results show that the values and motivations identified by the various researches varied greatly, thus a thematic categorization followed in order to produce a useful conceptual framework for the analysis of quality food cognitive structures. In the second stage we validated the...

The Greek small farms paradigm: between decline and persistence
Provedor de dados: 31
Autores: Vounouki,   Eleftheria.
Although Greece is one of the older Member States of the European Union, its agricultural structures have not followed the same evolution compared to those of other Western European countries. In the majority of the latter, the number of farms and farmers has declined subsequently to the modernisation movement, while Greek agriculture has maintained a high number of farms and farmers. The Greek case can be considered as a paradigm between two EU country groups: the old and the new Member States. This paper deals with the reasons leading to this phenomenon: how do Greek farms manage to resist to an increasingly liberalised environment and to the reduction of EU and State financial support? Why do young people go on dealing with agriculture? This is a...

Efficiency in Damage Control Inputs: A Stochastic Production Frontier Approach
Provedor de dados: 31
Autores: Karagiannis,   Giannis; Tsionas,   Efthimios; Tzouvelekas,   Vangelis.
The present paper extents the existing literature providing a theoretically consistent framework for measuring input-specific technical efficiency in damage control inputs within a stochastic production frontier model. The theoretical framework for modeling damage control agents is based on Fox and Weersink (1995) model specification that allows for increasing returns on damage control inputs. The empirical model accounts veterinary expenses as the damage control input and it is applied on a panel data set of sheep farms in Greece during the 1989-92 period. The results suggest that sheep farms in Greece are using inefficiently immunization and antibiotics in their flock as their average technical efficiency level was 72.82%. On the other hand, technical...

Information Acquisition and Adoption of Organic Farming Practices
Provedor de dados: 31
Autores: Genius,   Margarita; Pantzios,   Christos J.; Tzouvelekas,   Vangelis.
This study offers an empirical framework for analyzing farmers' joint decisions to adopt organic farming practices and to seek technical (i.e., farming) information from various sources. To that end, a trivariate ordered probit model is specified and implemented in the case of organic land conversion in Crete, Greece. Findings suggest that the decisions of information acquisition and organic land conversion are indeed correlated, and different farming information sources play a complementary role. Structural policies improving the farmer's allocative ability are found to play an important role in encouraging organic farming adoption.

Provedor de dados: 31
Autores: Haque,   Imdadul; Rozakis,   Stelios; Ganko,   Ewa; Kallivroussis,   Leonidas.
Recent reforms in the Common Agricultural Policy and the sugar regime caused serious concerns for the future of the European sugar industry. At the same time, the European Commission considers transportation bio-fuels as a key factor for reducing reliance on imported fuels, emission levels of greenhouse gases and to meet rural development goals. Matching the sugar sector with bio-ethanol production may create opportunities for sustainable management of the existing sugar industry infrastructure and also serve bio-fuel policy targets. A partial equilibrium economic model is used in order to evaluate the shift from sugar to bio-ethanol production in Thessaly, Greece. In the agricultural feedstock supply and industrial processing sub-models are articulated...

INVESTIGATING THE "COMPLEMENTARITY HYPOTHESIS" IN GREEK AGRICULTURE: AN EMPIRICAL ANALYSIS
Provedor de dados: 31
Autores: Katrakilidis,   Constantinos P.; Tabakis,   Nikolaos M.
This study investigates determinants of private capital formation in Greek agriculture and tests the "complementarity" against the "crowding out" hypothesis using multivariate cointegration techniques and ECVAR modeling in conjunction with variance decomposition and impulse response analysis.  The results provide evidence of a significant positive causal effect of government spending on private capital formation, thus supporting the "complementarity" hypothesis for Greek agriculture.

CAP Reform and the Mediterranean EU-Member States
Provedor de dados: 31
Autores: Borresch,   Rene; Kavallari,   Aikaterini; Schmitz,   P. Michael.
In the previous years the Mediterranean Member States of the EU came across the Reform of the CAP and especially last year faced the second wave of the Reform for three typical Mediterranean products, namely cotton, olive oil and tobacco. In this paper a partial equilibrium model is used to simulate the impacts of decoupling, as a key point of the decided CAP Reform. The second wave of the Reform appears to be of crucial importance for the southern EU countries and although the producer's income is reduced, there are positive welfare effects.

Evading Farm Support Reduction via Efficient Input Use: The Case of Greek Cotton Growers
Provedor de dados: 31
Autores: Pantzios,   Christos J.; Rozakis,   Stelios; Tzouvelekas,   Vangelis.
The present paper examines the importance that efficient resource use may have for cotton growers under the current EU policy regime. To that end, input-oriented technical and scale efficiency score for a sample of 172 cotton-growing farms are empirically quantified. The results suggest that cotton farms in the sample are not efficient mainly due to the nature of the policy regime governing the sector throughout EU. By becoming efficient, the co-responsibility levy will be reduced by 18.3% and farms may increase their profits by 50.1% on the average.

Comparison of Industrial Dynamics of Food and Beverage Industry in Bulgaria, Romania and Greece
Provedor de dados: 31
Autores: Kopeva,   Diana Ilieva; Shterev,   Nikolay; Blagoev,   Dimitar.
Industry dynamic is a key indicator for sustainable industry growth. It depends on variety of factors on international and regional level. One of the important driving forces on international level is seen in the face of economic and political alliances. Cultural and regional policies, and social behaviour are driving industry dynamics on a regional level though. Our hypothesis is that specific differences of industrial dynamics of the Balkan countries occurred based on economic and political alliances (EU membership; Euro zone, Black Sea Economic Cooperation). This hypothesis is verified with analysis of a traditional for the Balkans industrial sector like Food and Beverage. The paper aims to find out more evidence to verify a basic hypothesis. It...

Investigating a Paradigm of Food System Sustainability:The Case of Fresh Vegetable Production and Distribution in Crete
Provedor de dados: 31
Autores: Apostolides,   Kristy; Kambourakis,   Emmanouil.
In opposition to the current paradigm of the globalized the food system, many regional initiatives have arisen to reorganize the food system into localized or regionalized supply chains. This study explores the existing food supply chain for field fruit and vegetable production within the island of Crete, Greece, by examining the production and distribution of food stuffs through the wholesale system and to determining the geographic and retail terminal points for these Cretan-produced items. Through case studies, this paper examines the typology of production and maps the distribution of vegetables and melons produced on the island as the first step to determining the current level of food system sustainability, and opportunities and barriers for greater...

Assessing the Perspectives of EU Cotton Farming: Technical and Scale Efficiencies of Greek Cotton Growers
Provedor de dados: 31
Autores: Pantzios,   Christos J.; Rozakis,   Stelios; Tzouvelekas,   Vangelis.
Utilizing the stochastic frontier approach, this paper estimates output and input-oriented technical and scale efficiency levels for a sample of cotton-growing farms in Thessaly, Greece. The empirical results suggest that Greek cotton farm operations are technically and scale inefficient. There is a considerable scope for improvement in resource use and thereby in farm income of cotton farms; Greek cotton farmers could reduce production costs by 20.4%, making more efficient utilization of the existing production technology. Factors responsible for the technical efficiency differentials observed among cotton-growers include the farmer's age and education as well as the farm's land fragmentation and output specialization.

Provedor de dados: 31
Autores: Boutsouki,   Christina; Zotos,   Yorgos; Masouti,   Zafeiria.
In Greece, the traditional perceptions of private label were once of low quality, unbranded alternatives, attracting the most cost-conscious consumers. In today’s private label market, however, a different level of products has emerged – the premium “branded” private label product. Based on a consumer survey conducted in Greece, the current study discusses consumer’s attitude and satisfaction with respect to private label products. Frequency of purchase and consumer characteristics are also discussed in light of empirical evidence.

New entrants policy into agriculture: researching new farmers’ satisfaction
Provedor de dados: 123
Autores: Chatzitheodoridis,Fotios; Kontogeorgos,Achilleas.
Abstract: During the last three decades, the European Union has adopted a series of policies aiming to increase the new farmers entering the primary sector. This scheme, namely the “New Entrants Policy”, is reflected to the relevant regulations of the Common Agricultural Policy. After many years of implementation, there is still limited information regarding young farmers’ perceptions and participation to this scheme. Against this backdrop, a questionnaire was developed in order to assess the degree of new farmer’s satisfaction on their decision to enter the agricultural sector by participating in this scheme. Furthermore, we tried to evaluate the factors and motivations that determined their decision. The survey was carried out in Greece during an...

Wild vegetables do not lie: Comparative gastronomic ethnobotany and ethnolinguistics on the Greek traces of the Mediterranean Diet of southeastern Italy
Provedor de dados: 39
Autores: Pieroni,Andrea; Cattero,Valentina.
ABSTRACT Bio-cultural and historical aspects of the “wild plant” portion of the Mediterranean Diet are still very much understudied despite the large number of bio-medical studies on the topic. The current gastronomic ethnobotanical and ethnolinguistic field study focused on the wild leafy vegetables used among Greek populations in SE Italy and NE Greece. A total of 52 folk taxa, corresponding to 58 wild botanical species, were recorded. The frequency of consumption of these wild ingredients was higher in NE Greece than in SE Italy, although approximately one-third of the recorded wild taxa overlapped in the two study sites. Most of these common species were designated by cognates, having in most cases a clear Greek origin, while one-third of the recorded...

Classification of Potential Sheep Heat-Stress Levels According to the Prevailing Meteorological Conditions
Provedor de dados: 111
Autores: Dimitris K. Papanastasiou.
Many researchers have found that physiology, welfare, health, and productivity of ruminants are significantly affected when they are exposed to heat-stress conditions. In such cases, heat-stress may also cause a reduction of farmers&amp;rsquo; profit in various ways. Heat-stress levels are significantly affected by the prevailing meteorological conditions. This paper aims to study the potential daily peak heat-stress conditions to which sheep are exposed and to classify them according to the prevailing meteorological conditions. For these purposes, temperature, relative humidity, wind speed and incoming solar radiation data were analyzed. The meteorological data were recorded during the summers of the period 2007 &amp;ndash; 2012 by an automated...

Optimal Financial Insulation Thickness of a Broiler House
Provedor de dados: 111
Autores: Panagakis- FBC, Panagiotis; Manolakos, Dimitris; Axaopoulos, Petros.
A common method for environmental control in livestock facilities is to use thermal insulation for exterior walls and roof. In regions with cool winters increasing the insulation thickness decreases the heating requirements, however in regions with hot summers may lead to unwanted increase of inside temperature, thus intensifying cooling loads. It is worth noting that financial thickness optimization of a broiler house external walls and gable roofs insulation for different orientations has not been sufficiently addressed, thus a detailed transient simulation was used to model existing energy audited broiler house and to calculate its annual heating and cooling loads. For that, hourly climatic data and all the heat and moisture gains and losses resulting...

Invasiveness of Cut-Leaf Ground-Cherry (Physalis angulata L.) Populations and Impact of Soil Water and Nutrient Availability
Provedor de dados: 117
Autores: Travlos,Ilias S.
Biological invasions are a major threat to natural ecosystems and agroecosystems, while weed flora is noticeably changing globally. In this study we evaluated the potential of cut-leaf ground-cherry (Physalis angulata L.), a species native to America, to invade the semi-arid regions of Greece. Greenhouse and laboratory experiments were conducted to evaluate the effects of different environmental resources (nutrient and water availability) on seedling growth, biomass production, fecundity, and seed germination of four populations of cut-leaf ground-cherry. Our results suggest that cut-leaf ground-cherry does not tolerate extreme drought during the first growth stages, while it can survive and produce adequate and rapidly germinated seed (&gt; 85%) under low...
