Laurentian Great Lakes Warming Threatens Northern Fruit Belt Refugia, Robert Warren

Biology Faculty Datasets

Climate refugia are anomalous ‘pockets’ of spatially or temporally disjunct environmental conditions that buffer distinct flora and fauna against prevailing climatic conditions. Physiographic landscape features, such as large water bodies, can create these micro-to-macro-scale terrestrial habitats, such as the prevailing westerly winds across the Laurentian Great Lakes that create relatively cooler leeward conditions in spring and relatively warmer leeward conditions in autumn. The leeward Great Lakes climate effects create a refugia (popularly known as a ‘fruit belt’) favorable for fruit-bearing trees and shrubs. This fruit belt refugia owes its existence to seasonal inversions whereby spring cooling prevents early flower budding …
