Assessment of Fish Biodiversity in P. oceanica seagrass meadows in Lipsi island   Posidonia oceanica is an endemic seagrass species of the Mediterranean Sea. Research in other areas of the Mediterranean Sea has shown that P. oceanica meadows provide habitats for a diverse fish community and they have an especially important role as breeding and
Population Assessment of the Mediterranean chameleon  The Mediterranean Chameleon (Chamaeleo chamaeleon) is one of only two existent species of Chamaleonidae in Europe. It can be found in the southern part of Spain, Portugal, Italy and Greece. Until a few decades ago, only a few parts of Greece supported populations of this species; namely the islands
Assessing the Grazing Activity of Sea Urchins Sea urchins are herbivorous animals that live on rocky substrate and graze on macroalgae. Pollution and overfishing of their predators, led to massive increase of the sea urchin population across the Mediterranean. As a consequence, macroalgae forests has tended to disappear, causing cascades effects on other organisms that
Comparison of Microplastics Found Within the Gastrointestinal Tract of Caretta caretta Megan J. Kelly, University of Salford Lauren .J. Kageler, Dickinson College   The pollutions of the oceans is a rising concern of environmentalists and researchers worldwide. Plastic production and its usage in several fields, from food packaging over water bottling to clothing, increased in

GIS Team, June 2017

Mapping Seagrass Meadows With Specially Equipped Kayaks   The GIS (Geographic Information Systems) team of Archipelagos Institute is spread out over Samos and Lipsi islands. They work in collaboration with other teams to create tools that facilitate better research, field work and communication of data. This means that GIS projects encompass smaller, more supportive tasks
Monitoring Strandings of Marine Mammals and Turtles   The Archipelagos Marine Mammal Research Team has collected for over 15 years, data from stranded marine animals including sea turtles (Caretta caretta), dolphins (Stenella coeruleoalba, Delphinus delphis, Tursiops truncatus), and monk seals (Monachus monachus) from various areas of Greece. The aim of this work is to determine
Development of a Methodology to Assess Anchor Damages on Posidonia Seagrass Meadows   Following the increase of coastal urbanization, 46% of the Posidonia oceanica meadows have disappeared or become threatened by a number of factors including boat anchoring. In the Aegean islands, where recreational yachting is a major touristic activity this environmental threat is an
Photo-Identification of Short Beaked Common Dolphins (Delphinus delphis)   The Marine Mammal Team of Archipelagos Institute has for many years been collecting photographs of the populations of the resident Short Beaked Common dolphins (Delphinus delphis) while conducting boat surveys. This valuable photographic material is then processed to perform photo identification via mark and recapture techniques.
Research Assessing the Dietary Preferences of Golden Jackals The Golden Jackals are opportunistic feeders, meaning that they will eat anything available, ranging from grapes and carobs to rodents and birds or even animal carcasses. The aim of this research project is to investigate the preference of seasonal and easy to find food, like carob or
Installation Project of Lipsi base On Lipsi Island, where the Aegean Marine Life Sanctuary will be located, the renewable energy team is aiming to create a research base and veterinary clinic that may fully function using renewable energy sources. With the average monthly sunshine on Lipsi reaching approximately 400 hours, and winter sunshine hours still

Media Team, December 2016

Material for awareness-raising on the threats of plastics This month Archipelagos’ media team, in cooperation with Microplastics research team, worked on posters and leaflets as a part of an awareness raising campaign in regards to “Why we are moving away from Plastic”. The main goal is to enlighten the public on how small plastic particles can leach from

Microplastics Team, December 2016

Analysis of the content of the gastrointestinal tract of a Loggerhead turtle (Caretta caretta) in the search for micro-plastics. At the beginning of November, a sea turtle stranding (Caretta caretta) on Psili Ammos beach allowed the start of a new study: micro-plastic research in stomach and intestinal contents. The sea turtle was necropsied and the

Habitat modelling of common dolphin, Delphinus delphis, in the Aegean Sea by using different dynamic models The aim of the project is to complete habitat modelling of common dolphins, Delphinus delphis, in the Aegean Sea by using different dynamic models.  Populations of marine mammals found in Mediterranean Sea are genetically distinct from their North Atlantic
Posidonia oceanica mapping Posidonia oceanica is an aquatic flowering plant endemic to the Mediterranean, instrumental in providing habitats and nursery grounds to a diverse array of species in the area. Although the seagrass is imperative to ecosystem health, conservation efforts have not mirrored this: Posidonia oceanica’s status is only listed as “least concern” in the
Research on the Golden Jackal of Samos Jackal diet preference survey Jackals are opportunistic feeders, meaning that they will eat anything available at the moment, ranging from grapes and carobs to rodents and birds or even animal carcasses. The aim of this survey is to investigate the preference of seasonal and easy to find food

Microplastics Team, November 2016

Studying Surface Water for Plankton & Microplastics In this project we collect sea surface water in the eastern Aegean Sea to find trends between the amount of plankton and microplastics and establish if a correlation exists. We hypothesise that greater quantities of plastics leads to fewer plankton in the neustonic layer leading to a greater

GIS Team, November 2016

Distribution model for common dolphins near the island of Samos The aim of this project is to develop a species distribution model (SDM) for common dolphins which takes into account dynamic environmental factors such as sea surface temperature, salinity and chlorophyll. SDMs take occurrence or abundance data about certain species and extrapolate this data in space and

Renewable Energy Team, November 2016

Applications of Small Scale Renewable Applications in the Aegean Sea islands Desalination stills Desalination stills are using the suns radiant energy to evaporate water. The evaporated water is then condensed again on a cool inside surface, where it drips down and is collected. Archipelagos’ prototype is a two slope basin solar still with a 20°
