Aegean Bath Sponges: Historical Data and Current Status
(2011)This study attempts to evaluate the status of the populations of bath sponges (species of the genera Spongia and Hippospongia) in the Aegean, combining historical sources dated before a series of disease outbreaks that ... -
Cosmopolitan heterotrophic microeukaryotes are active bacterial grazers in experimental oil-polluted systems
(2008)We investigated the population dynamics and prevailing 18S rDNA phylotypes of microeukaryotes (<= 10 mu m) in microcosms containing seawater from either an unpolluted oligotrophic site or a chronically oil-polluted mesotrophic ... -
Detection and Zoonotic Potential of Trichinella spp. from Free-Range Pig Farming in Greece
(2012)Trichinellosis is a serious parasitic zoonosis, which is widely distributed around the world. Pork meat is still the predominant source of outbreaks of human trichinellosis in many countries. The aim of this study is to ... -
Dietary differences are reflected on the gut prokaryotic community structure of wild and commercially reared sea bream (Sparus aurata)
(2014)We compared the gut prokaryotic communities in wild, organically-, and conventionally reared sea bream (Sparus aurata) individuals. Gut microbial communities were identified using tag pyrosequencing of the 16S rRNA genes. ... -
Different phytoplankton descriptors show asynchronous changes in a shallow urban lake (L. Kastoria, Greece) after sewage diversion
(2013)Phytoplankton long-term changes were examined in a shallow urban lake (L. Kastoria, Greece) after sewage diversion in nine distinct years from 1994-2010. Using different levels of phytoplankton descriptors (diversity, ... -
A new species of Halichondriidae, Topsentia vaceleti n. sp (Halichondrida, Demospongiae, Porifera), collected from coralligenous bottoms of the Aegean Sea
(2012)A new species, Topsentia vaceleti n. sp., was collected from 70m depth, on a coralligenous bed of the Aegean Sea by trawl (sponge fishing gear "gagava"). The specimen is spherical, 8 cm in diameter, with deep surface ... -
Population-specific demography and invasion potential in medfly
(2011)Biological invasions are constantly gaining recognition as a significant component of global change. The Mediterranean fruit fly (medfly) constitutes an ideal model species for the study of biological invasions due to its ... -
Selecting landscape metrics as indicators of spatial heterogeneity-A comparison among Greek landscapes
(2014)This paper investigates the spatial heterogeneity of three landscapes along an altitudinal gradient and different human land use. The main aim was the identification of appropriate landscape indicators using different ... -
Sponge epibionts on ecosystem-engineering ascidians: The case of Microcosmus sabatieri
(2010)The study of epibionts on habitat engineering ascidians is of increasing interest because changes in the population structure of the latter may affect associated communities, especially in the case of commercially exploited ... -
Sponges of economical interest in the Eastern Mediterranean: an assessment of diversity and population density
(2008)The aim of this paper was to investigate diversity and population density of sponges with manifest or potential economical interest for the first time in the Eastern Mediterranean. For this purpose, the area of Dodecanese, ... -
Temporal shifts of the Norway lobster (Nephrops norvegicus) gut bacterial communities
(2010)The aim of this study was to investigate the gut bacterial communities of Nephrops norvegicus individuals, using a suite of molecular tools consisting of automated ribosomal intergenic spacer analysis, 16S rRNA gene-internal ...
