Persistence of episomal HIV-1 infection intermediates in patients on highly active anti-retroviral therapy
(2000)Treatment of HIV-1-infected individuals with a combination of anti- retroviral agents results in sustained suppression of HIV-1 replication, as evidenced by a reduction in plasma viral RNA to levels below the limit of ...

Habitat diversity, ecological requirements of species and the Small Island Effect
(2009)Aim: To explore the causal factors leading to a significant Small Island Effect (SIE), that is, the absence of the commonly found species-area relationships below an island size, on the terrestrial isopod communities from ...

Hotspots of endemic terrestrial invertebrates in southern Greece
(2001)In the present paper we identify biodiversity hotspots of endemic terrestrial invertebrates in southern Greece, using four different criteria and five taxonomic groups. The hotspots identification procedure was facilitated ...

Article
From plots to islands: Species diversity at different scales
(2012)Aim To investigate how plant diversity of whole islands ('gamma') is related to alpha and beta diversity patterns among sampling plots within each island, thus exploring aspects of diversity patterns across scales. Location ...

Article
A comparison of terrestrial isopod communities among different habitat types on Mt. Chelmos (Peloponnisos, Greece)
(2012)The mountainous communities of terrestrial isopods (Crustacea, Oniscidea) have not been ex-tensively studied so far, even though they can offer important insights to the structuring of iso-pod diversity, to the role of ...

Article
The Aegean archipelago: A natural laboratory of evolution, ecology and civilisations
(2017)The Aegean archipelago, comprising numerous islands and islets with great heterogeneity in topographic, geological, historical and environmental properties, offers an ideal natural laboratory for ecological and evolutionary ...

Article
Patterns of taxonomic diversity among terrestrial isopods
(2015)The publication of the world catalog of terrestrial isopods some ten years ago by Schmalfuss has facilitated research on isopod diversity patterns at a global scale. Furthermore, even though we still lack a comprehensive ...

Article
Species co-occurrence: The case of congeneric species and a causal approach to patterns of species association
(2006)Aim: To test whether congeneric species are significantly associated with one another in space, either positively or negatively. Also, to provide a framework for a causal investigation of co-occurrence patterns by a parallel ...

Article
Altitudinal terrestrial isopod diversity
(2005)We have assessed the diversity of terrestrial isopods across an elevational and habitat gradient on Mt. Panachaiko (NW Peloponnisos, Greece). Previous knowledge on the biodiversity of this mountain was restricted to very ...

Article
From sampling stations to archipelagos: Investigating aspects of the assemblage of insular biota
(2004)Aim To investigate the formation of nestedness and species co-occurrence patterns at the local (sampling station), the intermediate (island group), and the archipelago scale. Location The study used data on the distribution ...

Revisiting the saproxylic beetle ‘Propomacrus cypriacus Alexis & Makris, 2002’ (Coleoptera: Euchiridae) using molecular, morphological and ecological data
(2017)Propomacrus cypriacus a saproxylic beetle endemic to Cyprus, was described as a species distinct from P. bimucronatus on the basis of a few morphological characters and has been evaluated as Critically Endangered by IUCN, ...

Article
A biogeographical analysis of terrestrial isopods (Isopoda, Oniscidea) from the central Aegean islands (Greece)
(1996)Terrestrial isopods (Isopoda, Oniscidea) of forty-three central Aegean islands and islets are analysed from a biogeographical point of view. The oniscid fauna consists of sixty-nine species, thirty-two genera anti fourteen ...

Article
The species-area relationship of terrestrial isopods (Isopoda
(1996)Data on species richness of terrestrial isopods (Oniscidea) from central Aegean islands (Greece), together with previously published data sets from other taxa and areas, are critically analysed under the basic premises of ...

Article
Altitudinal effect on species richness of Oniscidea (Crustacea
(1992)Species richness decreases with altitude, and at the same rate on all three mountains. The faunal similarity among altitudinal zones is inversely related to species density (total number of species present at each mountain), ...

Article
Testing for nestedness in the terrestrial isopods and snails of Kyklades islands (Aegean archipelago, Greece)
(1999)Most insular communities exhibit nestedness, with the species assemblages of the more depauperate islands constituting subsets of those of the richer. Several methods for the estimation and evaluation of nestedness have ...

Article
A biogeographical analysis of Greek Oniscidean endemism
(1998)Despite our incomplete knowledge of Greek Oniscidea, a great number of species have already been described, of which 69% are endemic. This unusually high percentage of endemics is a result of intense speciation triggered ...

N-alpha-terminal Acetylation of Histone H4 Regulates Arginine Methylation and Ribosomal DNA Silencing
(2013)Post-translational modifications of histones play a key role in DNA-based processes, like transcription, by modulating chromatin structure. N-terminal acetylation is unique among the numerous histone modifications because ...

Tail autotomy affects bipedalism but not sprint performance in a cursorial Mediterranean lizard
(2016)Running is essential in all terrestrial animals mainly for finding food and mates and escaping from predators. Lizards employ running in all their everyday functions, among which defense stands out. Besides flight, tail ...
