Even under today’s climatic conditions, the long-extinct straight-tusked elephant could still live in Europe. This is the conclusion of a recent study. For this finding, the Sport Ecology research group at the University of Bayreuth combined fossil finds with reconstructions of past climates. The researchers present their findings in the journal Frontiers of Biogeography.

What for?
Our perception of nature is shaped by what we experience in our surroundings. Ecosystems without direct human influence are often perceived as “natural.” However, when considering insights gained from fossils, it becomes clear that today’s ecosystems— even without direct human intervention—differ significantly from those in which the species of our landscapes evolved thousands of years ago. Studies like the one carried out by the Bayreuth research team highlight the importance of studying past ecosystems for conservation. Understanding how climate and environmental changes have historically affected large mammals can provide valuable insights for modern conservation strategies.

Elephants are among the largest land mammals on Earth and are often referred to as “ecosystem engineers” because they sustainably alter their surroundings through grazing, trampling, and digging. Europe, too, had an elephant: the straight-tusked elephant (Palaeoloxodon antiquus) lived on our continent for around 700,000 years. The species survived multiple ice ages before becoming extinct during the last one due to additional hunting pressure from humans. Throughout its existence, the straight-tusked elephant helped shape Europe's landscape, maintaining open spaces and light woodlands. Many native plant species are still adapted to these conditions today.
“The German name Waldelefant (forest elephant) originates from the assumption that this species primarily lived in the wooded regions of Europe. However, fossil evidence shows that P. antiquus often inhabited open or semi-open habitats with mosaic-like vegetation, similar to modern elephants,” explains Prof. Dr. Manuel Steinbauer, Chair of Sport Ecology at the University of Bayreuth.
To reconstruct the way of life of P. antiquus and, in particular, its actual habitat—known as the realised niche—the research team examined scientific literature and palaeontological databases for fossil finds of P. antiquus that could be assigned to specific Marine Isotope Stages. Marine Isotope Stages are periods in the earth's history that reflect climate history, representing warm and cold stages. The Bayreuth research team assigned fossil finds from across Europe to either a warm or cold stage and used climate models from these periods to reconstruct the realised niche of the straight-tusked elephant. A comparison with modern climate data suggests that straight-tusked elephants would still be able to live in Europe today. The climate in Western and Central Europe would be particularly suitable, except for mountainous regions such as the Alps and the Caucasus.
“In the past, megafauna like the straight-tusked elephant and their regulatory mechanisms—such as grazing—were omnipresent. Many European species, particularly plants that thrive in open habitats, likely established in their diversity in Europe because they benefited from these ecological influences. Traditional conservation strategies in Europe primarily aim to protect biodiversity by shielding habitats from human activities. However, this strategy alone is unlikely to restore the lost ecological functions of megafauna,” says Franka Gaiser, a doctoral student in the Sport Ecology research team and lead author of the study.
Modern conservation projects actively reintroduce large herbivores to Europe. However, this comes with challenges, as the ecological processes that have shaped modern ecosystems are not yet fully understood. Additionally, today’s large herbivores cannot entirely replace the role of extinct megafauna, as both the animals themselves and the landscape structures, as well as species interactions, have changed significantly.
