Introduction & Background With an increasing awareness of the growing level of plastic in the environment, human activity has a significant impact on the health of both marine and terrestrial ecosystems. After one year of daily macroplastic surveys on remote coasts of Samos, a new project was inititated this spring aiming to assess the influx
Seagrass, in particular Posidonia oceanica, plays an important role in the ecosystem and provides several services. It ensures the maintenance of physical, chemical and biological conditions. It provides a habitat for many different species, is a nursery, hunting and predator area. Furthermore, it mediates flow, is a coastal erosion protection by stabilizing the sea beds and it decreases the water power
The Aegean Sea hosts some of the most important remaining marine mammal and sea turtle populations in the Mediterranean. Thanks to their unique biodiversity and pristine waters, the islands attract many sea enthusiasts all year long, especially during the summer season. Bad encounters between boats and mammals are common and can have disastrous consequences for animals.
What is an artificial reef and why are we developing and using one? The artificial reef project has been ongoing since March 2017. It is a long-term project with the aim to successfully create reefs that increase biodiversity in the surrounding waters. The project is still in its experimental stage, but the long-term aim is
Have you ever stood on the shoreline, with waves lapping back and forth and allowed your mind to dive down into the mysterious world that lies beneath the waves? What creatures prowl the depth in search of their next meal? Dolphins, Sharks, Giant squid? What if I tell you that this mystery can be solved
Common dolphin (D. delphis) bioacoustics project – a study about vocalization and sociality of the common dolphin population in the Aegean Sea, February-March 2018. Common dolphins often live in pods consisting of around 12-20 individuals in the Mediterranean Sea (Murphy et al., 2008). The population of this particular species has been declining at an alarming
  Mankind is having a major impact on every ecosystem on earth. 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 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
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
