On Golem Grad Island in North Macedonia, an alarming behavioral observation has emerged among the Mediterranean turtle population. Male turtles aggressively pursue the few available females, creating an untenable environment where these females are not only harassed but often driven to extreme actions, such as jumping off cliffs. Dragan Arsovski, an ecologist who has been studying these turtles since 2008, indicates that what once seemed like a humorous sight has revealed a darker reality, culminating in population decline due to overcrowding of aggressive males and the distress faced by females.

The island, characterized by its steep cliffs and sparse female turtles, creates a setting where the relentless mating attempts by males lead to dire consequences. The situation has been examined in a recent article published in 'Ecology Letters', which documented the heightened risks to females due to the aggressive behavior of males chasing them. With an estimated thousand Mediterranean tortoises present on the island, the skewed ratio of aggressive males to submissive females places tremendous pressure on the surviving females, further limiting their chances of reproduction.

As the ecological dynamics unfold on Golem Grad Island, the implications of such behavior extend beyond immediate animal welfare concerns to highlight broader issues of biodiversity and environmental health. The aggressive mating practices that lead to female turtles leaping off cliffs signal an urgent need for conservation efforts to stabilize the population and mitigate the risk of extinction. Without intervention, the future of these Mediterranean turtles—already facing significant challenges—may be jeopardized even further, underscoring the delicate balance of ecosystems.
