This chapter explores the growing threats faced by top predators in the Mediterranean Sea. Climate change, overfishing, and plastic pollution may affect their migration patterns and lead them to abandon established reproduction areas. For instance, tuna might not find its spawning grounds due to warmer water, sea turtles might fight against plastic debris to lay…
This summer, I spent two months on the island of Lesvos, Greece, the setting of the National Science Foundation-sponsored Pollinators, Climate Change, and the Aegean Archipelago Research Experience for Undergraduates (REU). Our team of seven students and four senior researchers from various backgrounds in the U.S. worked to untangle the interacting stressors impacting bees in…
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…
Fire regime is predicted to change, particularly in Mediterranean climate regions, towards more severe and frequent fire events. From a predictive perspective, trait-based ecology offers a comprehensive framework to characterize vegetation responses to fire. Since fires induce erosion and decrease soil nutrients, species’ functional traits and their distribution at community level should reflect these changes….
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….
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…
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…
Environmental lawyers say that the new concessions threaten endangered species in the biodiversity-rich Hellenic Trench. Greece is allowing US fossil fuel giant Chevron to drill next to a protected coastal area, sparking a legal complaint from green NGOs. The government announced in January that it would be opening up new areas for offshore oil and…
Butterflies are disappearing in the United States. All kinds of them. With a speed scientists call alarming, and they are sounding an alarm. A sweeping new study published in Science for the first time tallies butterfly data from more than 76,000 surveys across the continental United States. The results: between 2000 and 2020, total butterfly…
Researchers at Göttingen University show keys to nature conservation measures at landscape level How can the loss of species and habitats in agricultural landscapes be stopped? Up to now, measures have mostly been implemented by individual farms. In contrast, agri-environmental measures that are planned across farms at landscape level offer greater potential for creating suitable…
