Unraveling Biodiversity Patterns: Climate's Impact Over Time

Explore the historical changes in biodiversity due to climatic shifts, from past glacial periods to interglacial eras, revealing the intriguing dynamics of species diversity development. Delve into the research by Duane Griffin from the Geography Department to understand the impact of climate fluctuations on biodiversity. Reflect on Alexander von Humboldt's musings on the uneven weave of the Earth's verdant carpet. Join the discourse on whether the tropics are a cradle or a museum for species gains and losses. Uncover the mysteries of the diversity gradient and its evolution throughout the millennia.

  1. What Happened to BiodiversityLast Time Climate Ran Amok? Duane Griffin Geography Dept

  2. The carpet of flowering verdure spread over the naked crust of the Earth is unevenly woven: more tightly where the sun rises higher in the…skies, more loosely nearer the inert poles. Alexander von Humboldt 1808

  3. Why? Species gains and losses Tropics: Cradle or Museum?

  4. Cradle or Museum?
