Aldrovandi's Herbarium

Central Idea

  • Researchers have found a 500-year-old herbarium from Italy, particularly Bologna in the north.
  • This collection, meticulously crafted by Italian naturalist Ulisse Aldrovandi between 1551 and 1586, offered a window into the past.

Aldrovandi’s Herbarium

  • Floristic Changes: The herbarium, containing 5,000 specimens, unveiled a tapestry of historical changes in Italy’s flora over five centuries.
  • Human Impact: Clues of human disturbance, habitat loss, transformation, and the invasion of alien species emerged from the pressed and preserved plant specimens.
  • Climate Change: The collection allowed insights into the impact of climate change on Italy’s botanical landscape.
  • Demographic Trends: European demographic shifts, excluding the European part of the former USSR, were reflected in the herbarium.
  • Extinct and Unknown Species: The herbarium hinted at species, both native and alien, that have vanished or remain undiscovered in contemporary times.

Legacy of Transformation

  • New World Influence: Aldrovandi’s herbarium holds the memory of Europe’s first encounters with species from the Americas, which later invaded the continent.
  • Transforming Flora: It documents the initial signs of a profound transformation in European flora and habitats, paving the way for the introduction of new species and ecological shifts.
