Effect of nitrogen concentration, two-stage and prolonged cultivation on growth rate, lipid and protein content of Chlorella vulgaris
(2019)BACKGROUND: The effects of the initial nitrogen concentration, as well as of two-stage and prolonged cultivation on the growth rate, lipid and protein content of Chlorella vulgaris were examined. Additionally, a kinetic ... -
Energy budget in organic and conventional olive groves
(2007)An energy analysis, combined with an economic one, in conventional and organic olive groves is useful in evaluating present situation and deciding best management strategies. The objective of this study was to evaluate the ... -
Energy flow for integrated apple production in Greece
(2006)Integrated production requires constant improvement of methods employed to achieve high fruit quality and yield with minimal inputs. This work was undertaken to evaluate the energy inputs for apple production, to identify ... -
Evaluation and cross-comparison of vegetation indices for crop monitoring from sentinel-2 and worldview-2 images
(2017)Farmers throughout the world are constantly searching for ways to maximize their returns. Remote Sensing applications are designed to provide farmers with timely crop monitoring and production information. Such information ... -
Evaluation of Growth Media Incorporating Cotton Ginning By-products for Vegetable Production
(2012)The suitability of by-products from the cotton ginning industry for incorporation into growth media for three vegetable crops was examined. Composts were prepared by mixing the by-product with soil in 5 ratios (20:80, ... -
Evidence for European brown hare syndrome virus introduction with translocated brown hares (Lepus europaeus): implications for management of restocking operations
(2013)Context. Criticisms of wildlife restocking operations typically focus on concerns that translocations can lead to the introduction of pathogens, and risk the integrity of locally adapted genetic diversity. Restocking ... -
Exploring the existence of Kuznets curve in countries' environmental efficiency using DEA window analysis
(2009)This paper, using data envelopment (DEA) window analysis and generalized method of moments (GMM) estimators, examines the existence of a Kuznets type relationship between countries' environmental efficiency and national ... -
Exposure of Eurasian magpies and turtle doves to West Nile virus during a major human outbreak, Greece, 2011
(2012)A major number of West Nile virus (WNV) infections in humans occurred in 2010 in northern Greece, with 262 laboratory confirmed cases. In 2011, fewer cases were reported, but the pattern was more dispersed throughout the ... -
Extraction Parameters Significantly Influence the Quantity and the Profile of PLFAs Extracted from Soils
(2011)Phospholipid fatty acid (PLFA) analysis is a robust method for characterizing soil microbial communities. We determined the effects of extraction solvent (chloroform vs dichloromethane) and buffer (phosphate vs citrate) ... -
Fishing down, fishing through and fishing up: fundamental process versus technical details
(2011)Fishing through, fishing up (i.e. the observation that mean trophic levels [MTLs] of catches are increasing with time) and the question of agreement between MTL from catches and surveys have been used to question fishing ... -
From trickle to flood: the large-scale, cryptic invasion of California by tropical fruit flies
(2013)Since 1954, when the first tropical tephritid fruit fly was detected in California, a total of 17 species in four genera and 11 386 individuals (adults/larvae) have been detected in the state at more than 3348 locations ... -
Genetic evidence for survival of released captive-bred brown hares Lepus europaeus during restocking operations in Greece
(2007)To prevent the decline of the brown hare Lepus europaeus, especially as a result of hunting pressure, restocking programmes, using hares from elsewhere, were carried out in Greece up to 2001. Using diagnostic RFLP mitochondrial ... -
Genetic structure of Greek brown hare (Lepus europaeus) populations as revealed by mtDBNA RFLP-PCR analysis: implications for conserving genetic diversity
(2001)The genetic differentiation and the phylogenetic status of brown hare (Lepus europaeus) populations from central Greece as well as the impact of the releases of reared individuals on the native populations genetic structure ... -
Hazards that threaten Greek wetlands: The case of Lake Koronia
(2008)Wetlands all over the world have been recognized as some of the most productive, multifunctional and dynamic ecosystems and they are under protection according to European Union legislation. However, they are under imminent ... -
Human impact on avian diversity in rural Mediterranean areas
(2015)Human activities influence the biodiversity of Mediterranean ecosystems and are involved in the transformation of natural habitats into farmland. We surveyed birds using the point count method on 288 plots at a 50-m radius ... -
Impact of a beneficial and of a pathogenic Fusarium strain on the fingerprinting-based structure of microbial communities in tomato (Lycopersicon esculentum Milll.) rhizosphere
(2011)Fusarium solani strain FsK (FsK), isolated from a plant pathogen-suppressive compost, grows endophytically in tomato roots and controls infestations by Fusarium oxysporum f.sp. radicis-lycopersici (FORL). The effect of ... -
The Impact of Biofumigation and Chemical Fumigation Methods on the Structure and Function of the Soil Microbial Community
(2011)Biofumigation (BIOF) is carried out mainly by the incorporation of brassica plant parts into the soil, and this fumigation activity has been linked to their high glucosinolate (GSL) content GSLs are hydrolyzed by the ... -
Impact of Fungicides on the Diversity and Function of Non-target Ammonia-Oxidizing Microorganisms Residing in a Litter Soil Cover
(2012)Litter soil cover constitutes an important micro-ecosystem in sustainable viticulture having a key role in nutrient cycling and serving as a habitat of complex microbial communities. Ammonia-oxidizing bacteria (AOB) and ... -
