We list via barcode/ISBN so please note that the images are stock images and may not be the exact copy you receive, furthermore the details about edition and year might not be accurate as many publishers reuse the same ISBN for multiple editions and as we simply scan a barcode or enter an ISBN we do not check the validity of the edition data when listing.

We aim to dispatch prompty, the service used will depend on order value and book size. We can ship to most countries, see our shipping policies. Payment is via Abe only.…

Soft cover. Etat : Very Good. 1st Edition. 771-779 pages with tables, map and graph. Quarto (11" x 8 1/4") bound in original publisher's pictorial wrappers. Volume 173, number 3999. First edition. "Pleistocene Changes in the Fauna and Flora of South America" (published in Science, 1971), challenged the long-held belief that tropical regions remained environmentally stable during the Quaternary. Instead, biological and geological data reveal dynamic shifts. The paper revolutionized historical biogeography by challenging the long-held assumption that the tropical regions of South America had remained ecologically stable for millions of years. Before this work, scientists believed that while Eurasia and North America suffered massive glacial disruptions during the Pleistocene epoch, the South American tropics remained largely unchanged. Vuilleumier demonstrated that South America was actually highly unstable and deeply impacted by climatic shifts. Instead of ice sheets, the main drivers of change in tropical South America were alternating dry (arid) and wet (humid) cycles. Vuilleumier's paper served as a crucial springboard and synthesist piece for the "Refugia Hypothesis" (pioneered around the same time by ornithologist Jürgen Haffer). By providing comprehensive biological data on both high Andean montane birds/plants and lowland fauna, she offered a unified explanation for why South America, particularly the Amazon basin, possesses such an extraordinarily dense wealth of biodiversity today.
