The Aegean Sea is one of the marine areas of our planet that has maintained its mystique throughout time. One of the species contributing to this mystique is the Mediterranean monk seal (Monachus monachus). The species has inhabited the waters of the Aegean since classical times, a fact that was well-known to ancient Greeks. Unfortunately, gradual,...

Understanding behavioral ontogeny is important for the successful conservation of endangered marine mammals. This is particularly the case for phocid seals, as during the early stages of their life they must acquire, largely independently, essential survival skills. We studied the maternal behavior and early behavioral ontogeny of the Mediterranean...

• Small‐scale fisheries may pose a serious threat to the conservation of marine mammals. At the same time various factors have led to the decline of small‐scale fisheries, often making them unsustainable. Current rates of biodiversity loss and the reduction of fish stocks and fisheries dictate a thorough understanding of fisheries‐related issues an...

The Aegean and Ionian Seas in Greece host currently the largest population of the endangered Mediterranean monk seal (Monachus monachus). The species is the only pinniped of the Mediterranean Sea that uses marine caves (monk seal shelters) with specific morphological characteristics for resting and pupping. The existence of such marine caves is of...

Mixed species groups (MSG) occur among different mammalian species, ranging from related species to species belonging to different orders. MSG may enhance foraging and predator avoidance, or provide social benefits. These advantages, however, may not be equally distributed between the participating species. Although the habitat of Mediterranean com...

The National Marine Park of Alonissos, Northern Sporades (NMPANS) is the largest Marine Protected Area in Greece (2220 km2). In the summers (June – September) of 2013–2015 and 2017–2018, we conducted boat-based surveys to study the poorly-known cetaceans of the NMPANS. Across 79 survey days and 2565 km of navigation, we encountered four species: co...
