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 ...

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 ...

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 ...

Current and future suitability of wintering grounds for a long-distance migratory raptor
Kassara, Christina; Gangoso, L.; Mellone, U.; Piasevoli, G.; Hadjikyriakou, T. G.; Tsiopelas, N.; Giokas, Sinos; López-López, P.; Urios, V.; Figuerola, J.; Silva, R.; Bouten, W.; Kirschel, A. N. G.; Virani, M. Z.; Fiedler, W.; Berthold, P.; Gschweng, M. (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 ...

Distribution modelling of Eleonora's Falcon Falco eleonorae Géné, 1839 occurrence in its wintering grounds: A niche-based approach with satellite telemetry data
Kassara, Christina; Fric, Jakob; Sfenthourakis, Spyros (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. ...

Factors influencing the occurrence of Eleonora's falcon Falco eleonorae breeding colonies on Greek islands
Kassara, Christina; Fric, Jakob; Sfenthourakis, Spyros (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 ...

Nest-site preferences of Eleonora's Falcon (Falco eleonorae) on uninhabited islets of the Aegean Sea using GIS and species distribution models
Kassara, Christina; Dimalexis, Anastasios; Fric, Jakob; Karris, Georgios; Barboutis, Christos; Sfenthourakis, Spyros (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 ...

Synchronous parallel composition in a process calculus for ecological models
Toro, Mauricio; Philippou, Anna; Kassara, Christina; Sfenthourakis, Spyros (2014)In this paper we extend PALPS, a process calculus proposed for the spatially-explicit, individual-based modeling of ecological systems, with a synchronous parallel operator. The semantics of the resulting calculus, S-PALPS, ...

Variation in breeding parameters of Eleonora's falcon (Falco eleonorae) and factors affecting its reproductive performance
Xirouchakis, Stavros M.; Fric, Jakob; Kassara, Christina; Portolou, Danae; Dimalexis, Anastasios; Karris, Georgios; Barboutis, Christos; Latsoudis, Panagiotis; Bourdakis, Stratis; Kakalis, Eleftherios; Sfenthourakis, Spyros (2012)We gathered data for a four-year period (2004-2007) on the nesting ecology and reproductive performance of Eleonora's falcon in the Aegean Sea. We investigated in an indirect way the relation between clutch size and ...
