From the very tops of the tallest peaks to the deepest abysses in our oceans, the world is changing, and how we measure these impacts, is also changing. Bioindicator species are helping us understand how we have affected our world and can even
Microplastics in Edible Fish and Invertebrates
Thursday, 15 March 2018
Microplastics content found in edible fish and invertebrate species of the Eastern Aegean Sea, February 2018 The increasing abundance of marine plastic debris is a worldwide issue and it represents a critical threat in areas such as the Mediterranean Sea. Many studies so far already documented the negative effects of this global issue on marine
Quantifying Macroplastic Accumulation
Saturday, 10 March 2018
One of the projects of Archipelagos marine conservation team is the study and assessment of the litter that is accumulating on coastal zones, waterways and wildlife areas here on Samos and Lipsi islands. This litter has the potential to cause many fatalities both on land in the marine environment. Macroplastics are plastic pieces larger than
Abundance and Distribution of Echinoderms Throughout the Island of Samos
Tuesday, 30 January 2018
Echinoderms play an important role in marine, benthic ecosystems. They can be both carnivorous or, most importantly, grazers. The grazing of sea urchins specifically reduces the rate of colonization on bare rocks by settling organisms. This keeps algae in check, thereby enhancing the biodiversity of coral reefs. Despite that, echinoderms sometimes have large population swings
Seagrass mapping in the Aegean Sea
Friday, 12 January 2018
The last half year, the GIS-team was working out a method for seagrass mapping. Global seagrass meadows are under threat. Reduction of water clarity, climate change and dredging destroy meadows at an incredible speed of 1.5% a year. The mapping of the Greek seagrass meadows, especially the specie Posidonia Oceanica, remains behind and counteracts conservation
Determining the Ratio of Microplastic in Zooplankton in Surface Waters Surrounding Samos Island
Thursday, 21 December 2017
The presence of vast amounts of plastics in our oceans is cause for great concern for our marine wildlife due to their toxicity, persistence and ubiquity. With the production of plastics increasing, these pollutants are entering our oceans and breaking down into microplastics (MPs) at an ever-increasing rate. Microplastics are buoyant fragments of <5mm which
Jackals in Samos Airport
Thursday, 07 December 2017
This spring Archipelagos Institute started working with Samos International Airport to establish the population and distribution of the golden jackal (Canis aureus L.) in the airport area.

Maritime Traffic Impact on Seagrass Vitality and Invertebrate Richness
Thursday, 07 December 2017
Seagrass plays a vital role in the health of coastal ecosystems all across the world. It is useful in sediment stabilization and carbon storage, and it supports a very diverse set of organisms. The seagrass beds often house commercial invertebrate and fish species, and are therefore not only ecologically important but economically, as well. Seagrasses
Posidonia Oceanica Mapping in the Southeastern Aegean Sea
Monday, 20 November 2017
Posidonia oceanica meadows are one of the most valuable ecosystems of the Mediterranean Sea. Climate change, fishing activities and anthropogenic influences threaten the survival of these meadows. Since the 20th century, 30% of the seagrass meadows have disappeared. Therefore, there is an increasingly pressing need to map the current extent of the seagrass cover. The
