Assessing marine ecosystem response to nutrient inputs
(2001)The response of the Pagasitikos Gulf to enrichment caused by run-off fertilizers and the development and evolution of harmful algal blooms is investigated through ecosystem modelling. A standard generic complex model has ... -
Bacterioplankton growth on extracellular organic carbon from marine microalgal cultures
(2005)Marine bacterial growth on extracellular organic carbon (EOC) of Chlorella minutissima, Dimaliella tertiolecta and Chaetoceros gracilis was studied. EOC was retrieved after filtration of optimum growing algal cultures at ... -
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 ... -
Changes in heterotrophic Picoplankton community structure after induction of a phytoplankton bloom under different light regimes
(2019)Bacterial and archaeal diversity and succession were studied during a mesocosm experiment that investigated whether changing light regimes could affect the onset of phytoplankton blooms. For this, 454-pyrosequencing of the ... -
CHLfuzzy: a spreadsheet tool for the fuzzy modeling of chlorophyll concentrations in coastal lagoons
(2008)CHLFuzzy is a user-friendly, flexible, multiple-input single-output Takagi-Sugeno fuzzy rule based model developed in a MS-Excel (R) spreadsheet environment. The model receives a raw dataset consisting of four predictor ... -
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, ... -
Differential effect of hydroxen peroxide οn toxic cyanobacteria of hypertrophic mediterranean waterbodies
(2022)Cyanobacterial blooms have been known since ancient times; however, they are currently increasing globally. Human and ecological health risks posed by harmful cyanobacterial blooms have been recorded around the world. These ... -
Ecological implications of raw sewage sea disposal in Elefsis bay (Saronikos gulf, Greece)
(1997)The disposal of Athens wastewater at the entrance of the Elefsis bay constitutes the major source of nutrient pollution for the bay. This disposal combined with the absence of river discharge, lack of run off from cultivated ... -
Everything is not everywhere: Can marine compartments shape phytoplankton assemblages?
(2019)The idea that 'everything is everywhere, but the environment selects' has been seminal in microbial biogeography, and marine phytoplankton is one of the prototypical groups used to illustrate this. The typical argument has ... -
Haematococcus: A successful air-dispersed colonist in ephemeral waters is rarely found in phytoplankton communities
(2016)In a literature search, the presence of Haematococcus in phytoplankton communities and its biogeography were investigated. Haematococcus, although showing a wide biogeographical distribution, has been rarely found in ... -
Implementation of the Water Framework Directive: Lessons Learned and Future Perspectives for an Ecologically Meaningful Classification Based on Phytoplankton of the Status of Greek Lakes, Mediterranean Region
(2019)The enactment of the Water Framework Directive (WFD) initiated scientific efforts to develop reliable methods for comparing prevailing lake conditions against reference (or nonimpaired) states, using the state of a set ... -
A study of oil pollution effects on the ecology of a coastal lake ecosystem
(1997)This study aims to examine ecological affinities in Lake Koumoundourou in Central Greece. The main finding of the study is that, although the lake is heavily polluted by crude oil, the water circulation, which is assisted ... -
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 ... -
Warming and Acidification Effects on Planktonic Heterotrophic Pico- and Nanoflagellates in a Mesocosm Experiment
(2016)We studied the response of the heterotrophic flagellate (HF) community to the combined impact of warming and ocean acidification in a mesocosm experiment with a plankton community from the western Baltic Sea. We performed ... -
Zooplankton population seasonal variations in relation to nutrients. Case study of Lake Kastoria, Western Macedonia, Greece
(2017)In order to evaluate the trophic status of Lake Kastoria, seasonal pattern of nutrients, chlorophyll-a and zooplankton have been examined from January to December 2011. Lake Kastoria is a polymictic lake, characterized by ...
