The Aegean archipelago: A natural laboratory of evolution, ecology and civilisations
Sfenthourakis, Spyros; Triantis, Kostas A. (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 ...

Altitudinal effect on species richness of Oniscidea (Crustacea
Sfenthourakis, Spyros (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), ...

Altitudinal terrestrial isopod diversity
Sfenthourakis, Spyros; Anastasiou, Ioannis P.; Strutenschi, T. (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 ...

Altitudinal Variation of Oniscidean Communities on Cretan Mountains
Lymberakis, Petros; Mylonas, Moysis; Sfenthourakis, Spyros (Brill, 2003)In the present paper we present a study on the effect of geographical elevation on the communi- ties of terrestrial isopods. We analysed the patterns of species diversity and the phenology ofOnis- cidea ...

Are terrestrial isopods able to use stridulation and vibrational communication as forms of intra and interspecific signaling and defense strategies as insects do? A preliminary study in Armadillo officinalis
Cividini, Sofia; Sfenthourakis, Spyros; Montesanto, Giuseppe (2019)The capability of producing sounds and vibrations is well known in insects and is thought to be a form of intra- and interspecific communication. Sounds and vibrations are used and modulated for several aims such as ...

Between-island compositional dissimilarity of avian communities
Pitta, Eva; Kassara, Christina; Tzanatos, Evangelos; Giokas, Sinos; Sfenthourakis, Spyros (2014)Compositional dissimilarity patterns of biotic communities can vary among different types of insular systems and among taxa with different dispersal abilities. In this work we examined compositional dissimilarity patterns ...

Biodiversity patterns of terrestrial isopods from two island groups in the Aegean Sea (Greece): Species-area relationship, small island effect, and nestedness
Triantis, Kostas A.; Sfenthourakis, Spyros; Mylonas, Moisis (2008)Although almost one third of Aegean islands have an area smaller than 1 km2, very few studies have concentrated on this spatial Scale. We investigate biodiversity patterns of terrestrial isopods in 2 island groups (Kalymnos ...

Article
A biogeographical analysis of Greek Oniscidean endemism
Sfenthourakis, Spyros; Giokas, Sinos (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 ...

A biogeographical analysis of terrestrial isopods (Isopoda, Oniscidea) from the central Aegean islands (Greece)
Sfenthourakis, Spyros (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 ...

Biogeography of body size in terrestrial isopods (Crustacea: Oniscidea)
Karagkouni, Maria; Sfenthourakis, Spyros; Feldman, A.; Meiri, S. (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: ...

Community variation of spiders, beetles and isopods in three small island groups of the Aegean Sea: the interplay between history and ecology
Pitta, Eva; Kassara, Christina; Trichas, Apostolos; Sfenthourakis, Spyros; Chatzaki, Maria (2017)Aim: To study the variation in the species turnover and nestedness components of compositional dissimilarity in a multi-taxa and multi-island-group system. In addition, to examine the influence of several biogeographical ...

Article
A comparison of terrestrial isopod communities among different habitat types on Mt. Chelmos (Peloponnisos, Greece)
Sfenthourakis, Spyros; Skouras, D.; Anastasiou, Yiannis (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 ...

Competition for shelter occupancy between a native freshwater crab and an invasive crayfish
Savvides, P.; Louca, V.; Sfenthourakis, Spyros (2015)Potamon potamios populations have decreased significantly due to the degradation of its habitat caused by human activities, mainly the use of insecticides. Today, P. potamios is protected by Cypriot law, but not much ...

Complementing the puzzle of Eleonora's Falcon (Falco eleonorae) migration: New evidence from an eastern colony in the Aegean Sea
Kassara, Christina; Fric, Jakob; Gschweng, M.; Sfenthourakis, Spyros (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 ...

Compositional dissimilarity patterns of reptiles and amphibians in insular systems around the world
Pitta, Eva; Kassara, Christina; Giokas, Sinos; Sfenthourakis, Spyros (2013)Several studies have shown that taxa with poor dispersal ability have a higher level of compositional dissimilarity than good dispersers. However, compositional dissimilarity patterns between islands with respect to dispersal ...

Deterministic assembly and anthropogenic extinctions drive convergence of island bird communities
Triantis, Kostas A.; Rigal, Francois; Whittaker, Robert J.; Hume, Julian P.; Sheard, Catherine; Poursanidis, Dimitrios; Rolland, Jonathan; Sfenthourakis, Spyros; Matthews, Thomas J.; Thebaud, Christophe; Tobias, Joseph A. (Wiley, 2022-06-10)Aim Whether entire communities of organisms converge towards predictable structural properties in similar environmental conditions remains controversial. We tested for community convergence in birds by comparing the ...
