A quorum sensing regulated small volatile molecule reduces acute virulence and promotes chronic infection phenotypes
(2011)A significant number of environmental microorganisms can cause serious, even fatal, acute and chronic infections in humans. The severity and outcome of each type of infection depends on the expression of specific bacterial ...

Whole-genome fetal and maternal DNA methylation analysis using MeDIP-NGS for the identification of differentially methylated regions
(2016)DNA methylation is an epigenetic marker that has been shown to vary significantly across different tissues. Taking advantage of the methylation differences between placenta-derived cell-free DNA and maternal blood, several ...

Topologically constrained domains of supercoiled DNA in eukaryotic cells
(1997)The size of supercoiled, topologically constrained DNA domains within the squamous carcinoma cell line SQ-20B were determined by direct comparison with a panel of irradiated supercoiled plasmid DNAs. Loss of supercoiling ...

Nest-site preferences of Eleonora's Falcon (Falco eleonorae) on uninhabited islets of the Aegean Sea using GIS and species distribution models
(2012)Eleonora's Falcon breeds colonially on small islands of the Mediterranean Sea and Macaronesia. Despite the wealth of papers highlighting the importance of nesting characteristics on this species' breeding performance, few ...

Article
Complementing the puzzle of Eleonora's Falcon (Falco eleonorae) migration: New evidence from an eastern colony in the Aegean Sea
(2012)Eleonora's Falcon (Falco eleonorae) is an endemic breeder of the Mediterranean Sea and the Canary Islands that overwinters in Madagascar and surrounding areas. Recent telemetry studies have revealed the migratory journey ...

Article
Estimating the population size of Scopoli's Shearwaters (Calonectris diomedea) frequenting the Strofades islands (Ionian Sea, western Greece) by raft counts and surveys of breeding pairs
(2017)The Strofades Island complex in the Ionian Sea comprises two small islands, i.e. Stamfani and Arpyia, and several rocks. The islands host a significant Scopoli's Shearwater (Calonectris diomedea) colony, which is regarded ...

Article
Does by-catch pose a threat for the conservation of seabird populations in the southern ionian sea (eastern Mediterranean)? A questionnaire-based survey of local fisheries
(2013)A significant number of studies worldwide have shown that incidental catches (by-catch) of seabirds in fishing gear might pose a considerable risk for the conservation of their populations. Nevertheless, reliable data on ...

Article
Factors influencing the occurrence of Eleonora's falcon Falco eleonorae breeding colonies on Greek islands
(2013)During the breeding seasons of 2004-2006, the population of Eleonora's falcon Falco eleonorae was censused on > 900 islands in the Ionian and the Aegean Seas, Greece. However, only one third of the islands hosted breeding ...

Distribution modelling of Eleonora's Falcon Falco eleonorae Géné, 1839 occurrence in its wintering grounds: A niche-based approach with satellite telemetry data
(2014)Summary Eleonora's Falcon is a long-distance migrant of the Palearctic region. In recent years, the advent of satellite telemetry has enabled a more detailed investigation of the species's migratory and wintering periods. ...

Article
Sex determination of scopoli's shearwater (calonectris diomedea) juveniles: A combined molecular and morphometric approach
(2013)The absence of juvenile sexual dimorphism in birds often impedes sex determination using external morphology. We examined sex ratio variation in Scopoli's Shearwater (Calonectris diomedea) fledglings (n = 135) on a Strofades ...

Article
Current and future suitability of wintering grounds for a long-distance migratory raptor
(2017)Conservation of migratory species faces the challenge of understanding the ecological requirements of individuals living in two geographically separated regions. In some cases, the entire population of widely distributed ...

Article
The island rule is not valid in terrestrial isopods (Crustacea: Oniscidea)
(2017)The island rule posits that small animals grow larger on islands, whereas large-bodied ones are expected to dwarf, but remains largely unexplored in invertebrates. We tested the rule at an inter-specific level on terrestrial ...

Environment shapes the digestive performance in a Mediterranean lizard
(2017)An efficient digestive system is of pivotal importance for survival as it governs the energy flow from the environment to organisms. Reptiles require relatively little energy, and their digestive system can readily respond ...

LiSIs: An online scientific workflow system for virtual screening
(2015)Modern methods of drug discovery and development in recent years make a wide use of computational algorithms. These methods utilise Virtual Screening (VS), which is the computational counterpart of experimental screening. ...

Article
The bacterial metabolite 2-aminoacetophenone promotes association of pathogenic bacteria with flies
(2014)Bacteria contaminate insects and secrete metabolites that may affect insect behaviour and potentially fitness through unknown mechanisms. Here we show that the 'grape-like' odorant 2-aminoacetophenone (2AA), secreted by ...

Biogeography of body size in terrestrial isopods (Crustacea: Oniscidea)
(2016)This study tries to unveil the contribution of climatic shift in shaping the extreme body size diversity in terrestrial isopods (Oniscidea). Trying to explain size variation at an interspecific level, we test five hypotheses: ...
