Airborne microeukaryote colonists in experimental water containers: diversity, succession, life histories and established food webs
(2011)Airborne freshwater and marine microeukaryotes in the city of Thessaloniki, situated in Thermaikos Bay, Greece, were examined as sources of colonization of experimental water containers during the period autumn 2007 to ... -
Analysis of olive fly invasion in California based on microsatellite markers
(2009)The olive fruit fly, Bactrocera oleae, is the main pest of the olive fruit and its expansion is exclusively restricted to the cultivation zone of the olive tree. Even though olive production has a century-old history in ... -
Apparent richness and community composition of Bacteria and Archaea in geothermal springs
(2009)The archaeal and bacterial 16S rRNA gene diversities of the Polihnitos (89 degrees C), Edipsos (81.8 degrees C), Thermopiles (38.9 degrees C), Eleftheres (41.2 degrees C) and Lagadas (35.2 degrees C) geothermal springs in ... -
Are Leaf Glandular Trichomes of Oregano Hospitable Habitats for Bacterial Growth?
(2012)Phyllospheric bacteria were isolated from microsites around essential-oil-containing glands of two oregano (Origanum vulgare subsp. hirtum) lines. These bacteria, 20 isolates in total, were subjected to bioassays to examine ... -
Assessment of microcystin distribution and biomagnification in tissues of aquatic food web compartments from a shallow lake and evaluation of potential risks to public health
(2012)The objectives of this study were: (1) to examine the distribution and bioaccumulation of microcystins in the main components of the food web (phytoplankton, zooplankton, crayfish, shrimp, mussel, snail, fish, frog) of ... -
Assessment of site specific benthic impact of floating cage fanning in the eastern Hios island, Eastern Aegean Sea, Greece
(2006)The site specific impact on the benthic fauna was assessed within a 4.64 km(2) area of intensive aquaculture situated on the eastern side of Hios island (Aegean Sea, Greece) at I I stations seasonally between November 2000 ... -
Beetle-robot hybrid interaction: sex, lateralization and mating experience modulate behavioural responses to robotic cues in the larger grain borer Prostephanus truncatus (Horn)
(2020)Ethorobotics, a new fascinating field of biorobotics, proposes the use of robotic replicas as an advanced method for investigating animal behaviour. This novel research approach can also encourage the development of advanced ... -
Beyond the manual: Practicing deliberative visioning in a Greek island
(2009)Deliberative visioning refers to processes of inclusive, multi-stakeholder deliberation over a desirable future. Methodologies include scenario workshops, future searches and community visioning. This paper looks critically ... -
Bird community characteristics as indicators of sustainable management in olive grove ecosystems of Central Greece
(2015)The role of breeding birds as indicators of sustainable management in olive groves was investigated. The data revealed significantly higher alpha diversity in organic and abandoned olive groves and maquis than in conventional ... -
Climate-related geographic shift and sudden population increase of a small pelagic fish (Sardinella aurita) in the eastern Mediterranean Sea
(2008)Round sardinella (Sardinella aurita) is a thermophilous small pelagic clupeid fish that is exploited by the purse-seine fishery across the Mediterranean Sea. For many years, its Aegean Sea distribution has been confined ... -
Comparison of essential oils and genetic relationship of Origanum x intercedens to its parental taxa in the island of Crete
(2002)Plants of the taxa Origanum onites and Origanum vulgare were allowed to cross-pollinate under natural open field conditions and to produce a mixed population of putative hybrid Origanum x intercedens and parent genotypes. ... -
Cuckoo and biodiversity: Testing the correlation between species occurrence and bird species richness in Europe
(2015)The use of biodiversity surrogates is an increasingly popular tool, because it provides strong results while reducing the costs of conservation studies. Here, we hypothesize that cuckoo (Cuculus canorus) occurrence may ... -
Determinants of visitor pro-environmental intentions on two small greek islands: Is ecotourism possible at coastal protected areas?
(2012)A relatively under-researched question is whether there is a possibility of influencing environmentally aware tourists regarding ecotourism at destinations that continue to develop under a pattern of mass 'seaside' tourism. ... -
Diapause termination of Rhagoletis cerasi pupae is regulated by local adaptation and phenotypic plasticity: escape in time through bet-hedging strategies
(2014)Persistence and thriving of univoltine, herbivore insect species of the temperate zone rely on obligate diapause response that ensures winter survival and synchronization with host phenology. We used a stenophagous fruit ... -
Dissipation of pure and broccoli-released glucosinolates in soil under high and low moisture content
(2013)Glucosinolates (GSLs) are secondary metabolites found in Brassica species. Upon tissue disruption GSLs are hydrolyzed by myrosinase enzymes to isothiocyanates (ITCs) which are highly toxic to microbes. Therefore the ... -
Diversity and Spatial Distribution of Prokaryotic Communities Along A Sediment Vertical Profile of A Deep-Sea Mud Volcano
(2011)We investigated the top 30-cm sediment prokaryotic community structure in 5-cm spatial resolution, at an active site of the Amsterdam mud volcano, East Mediterranean Sea, based on the 16S rRNA gene diversity. A total of ... -
Do Botanical Pesticides Alter the Structure of the Soil Microbial Community?
(2009)The effects of synthetic pesticides on the soil microbial community have been thoroughly investigated in the past mostly by culture-dependent methods and only few recent studies have used culture-independent approaches for ... -
Does natal habitat preference modulate cereal kernel preferences in the rice weevil?
(2013)The influence of larval diet source in Sitophilus oryzae (L.), a primary grain feeder, on the choice of a new cereal host by young adult was investigated through a multiple choice comparative bioassay. For this purpose, ... -
Ecotoxicological properties of wastewater treated using tertiary methods
(2006)The objective of this work was the examination of the efficiency of coagulation and ozonation processes for the production of reclaimed wastewater with low toxicity. Municipal secondary effluents were treated by FeCl 3, ... -
The effect of government expenditure on the environment: An empirical investigation
(2013)This paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980-2000. We estimate both the direct and indirect effects of government spending on pollution. ...
