Non-Indigenous Species (NIS) Know No Geopolitical Borders—An Update of NIS in the Aegean Sea

In this work, combined efforts by Greek and Turkish scientists produced an updated validated NIS inventory of the Aegean ecoregion, covering 120 years of records up to August 2024. Of the 342 NIS currently present in the Aegean Sea, the majority (281 species) have invaded the South Aegean, followed by the North Aegean (128 species…

Indications of Understorey Management Practices impact on Vascular Plant and Arthropod Diversity in Olive Groves on Lesvos, Greece

This study investigates the impact of three understorey management practices – herbicide application, understorey clearing, and undisturbed understorey – on the biodiversity of plant and arthropods in olive groves in the Gera region on Lesvos, Greece. The study found that herbicide application had a negative effect on plant diversity, but less pronounced effects on arthropods….

Lessepsian migration in the Mediterranean Sea in an era of climate change: Plague or boon?

The eastern Mediterranean Sea has suffered severe impacts from climate change, causing the decline of native biodiversity. Based on a global systematic review, we found that climate change has been the main driver of local extinctions globally since the 1990s; the eastern Mediterranean is flagged as an extinction hotspot. This region is also a bioinvasions…

Faunistic Study of Auchenorrhyncha in Olive Orchards in Greece, Including First Records of Species

The study of Auchenorrhyncha species composition in Greek olive orchards is crucial due to the potential threat of Xylella fastidiosa invading the region. Recent studies have begun exploring agricultural landscapes, particularly olive and citrus orchards. From 2016 to 2022, biodiversity surveys were conducted in thirteen olive orchards across three regions of Greece: Peloponnese, Sterea Ellada,…

New warnings of a ‘Butterfly Effect’ — in reverse

New warnings of a ‘Butterfly Effect’ — in reverse

A Yale-led study warns that global climate change may have a devastating effect on butterflies, turning their species-rich, mountain habitats from refuges into traps. Think of it as the “butterfly effect” — the idea that something as small as the flapping of a butterfly’s wings can eventually lead to a major event such as a hurricane…

Why Earthworms, Ants, and Termites Matter for Climate Health

Why Earthworms, Ants, and Termites Matter for Climate Health

A new Nature publication shows how soil invertebrates influence the world beneath our feet and thus also ecosystem services worldwide. Since the Industrial Revolution, global changes have led to a decline in biodiversity. To address these changes, it is crucial to understand what constitutes healthy ecosystems – and how to protect and build them. A…

New records of introduced species in the Mediterranean (August 2024)

This Collective article presents 18 introduced taxa in the Mediterranean Sea, belonging to seven phyla and documented at 22 new locations and seven countries spanning from the Levantine to the western Mediterranean. These records include the first country records of the African mussel Perna perna (Syria), the sea slug species complex Elysia cf. marginata-grandifolia (Cyprus),…

Notes on ants (Hymenoptera: Formicidae) of Lesvos island, Greece

With an area of 1,633 km2 and approximately 400 km of coastline, Lesvos isthe third-largest Greek island and the eighth-largest in the Mediterranean. Situated in the northeastern part of the Aegean archipelago and bordering Turkey, Lesvos has been known to host 59 ant species and morphospecies. In this article, we present a list of 84…

Evidencing the northward extension of loggerhead sea turtle nesting activity in the Aegean Sea, Greece: new records of sporadic nesting on Lesvos and Chios islands

The Mediterranean Sea hosts a diverse array of marine species, including the loggerhead sea turtle (Caretta caretta), a keystone species for conservation efforts. However, knowledge of its nesting localities within the Aegean Sea, particularly in the northern regions, remains limited. Here, we report the first documented instances of successful loggerhead turtle nesting and hatchling emergence…

Alien ants (Hymenoptera, Formicidae) on a quest to conquer Greece: a review including an updated species checklist and guidance for future research

Biological invasions represent one of the main drivers of biodiversity loss with adverse impacts on human societies, economies and public health. More than 500 ant species have been transported outside their native range with the help of humans, while the majority of them have managed to establish viable populations in the wild. Nevertheless, data from…
