Anthropogenic effects on bacterial diversity and function along a river-to-estuary gradient in Northwest Greece revealed by metagenomics
(2016)Studies assessing the effects of anthropogenic inputs on the taxonomic and functional diversity of bacterioplankton communities in lotic ecosystems are limited. Here, we applied 16S rRNA gene amplicon and whole-genome ... -
Aquaculture systems and pathological problems of new species reared in fresh water in Greece [Χαρακτηριστικά εκτροφής και παθολογικά προβλήματα νέων ειδών εκτρεφόμενων ψαριών γλυκού νερού οτην Ελλάδα]
(2017)Published data on growth and pathology of the fish species: Mugil cephalus (mullet) and Acipenser gueldestaedi (sturgeon), under intensive culture, is limited. In particular, data on dietary requirements is non-existing. ... -
A catastrophic change in a european protected wetland: From harmful phytoplankton blooms to fish and bird kill
(2022)Understanding the processes that underlay an ecological disaster represents a major scientific challenge. Here, we investigated phytoplankton and zooplankton community changes before and during a fauna mass kill in a ... -
Cyanotoxins as the “common suspects” for the Dalmatian pelican (Pelecanus crispus) deaths in a Mediterranean reconstructed reservoir
(2018)Toxic cyanobacterial blooms have been implicated for their negative consequences on many terrestrial and aquatic organisms. Water birds belong to the most common members of the freshwater food chains and are most likely ... -
Epidemiological investigation of Legionella pneumophila serogroup 2 to 14 isolates from water samples by amplified fragment length polymorphism and sequence-based typing and detection of virulence traits
(2016)The aim of this study is to explore the dispersion, clonality, and virulence of Legionella pneumophila serogroups 2 to 14 in the Greek environment. Eighty L. pneumophila serogroup 2 to 14 strains isolated from water ... -
Geochemical modeling of mercury in coastal groundwater
(2022)The systematic analysis of groundwater in the Greek island of Skiathos revealed a seasonal increase of total mercury concentrations after the extensive groundwater abstraction during the busy and heavily touristic summer ... -
Gravity currents with large salinity in a gravel bed valley: an experimental study
(2022)In the current study experiments in a valley (a composite cross-sectional tank consisting of a rectangular upper cross section and a lower trapezoidal) were performed. The purpose of this research is to study the gravel ... -
Irrigation of radish (Raphanus sativus L.) with microcystin-enriched water holds low risk for plants and their associated rhizopheric and epiphytic microbiome
(2020)Microcystins (MCs) are toxins produced during cyanobacterial blooms. They reach soil and translocated to plants through irrigation of agricultural land with water from MC-impacted freshwater systems. To date we have good ... -
Quantifying the changes in genetic diversity within sequence-discrete bacterial populations across a spatial and temporal riverine gradient
(2019)Recent diversity studies have revealed that microbial communities of natural environments are dominated by species-like, sequence-discrete populations. However, how stable the sequence and gene-content diversity are within ... -
Using H2O2 treatments for the degradation of cyanobacteria and microcystins in a shallow hypertrophic reservoir
(2016)Toxins produced by cyanobacteria in freshwater ecosystems constitute a serious health risk worldwide for humans that may use the affected water bodies for recreation, drinking water, and/or irrigation. Cyanotoxins have ...
