A Multidimensional Investigation Of The Niche: Geographic Distributions, Body Size, And Interspecific Interactions Of Late Quaternary North American Canidae, Melissa Pardi
Biology ETDs
A pressing conservation challenge is understanding how organisms will be impacted by climate change. From the paleontological record, we know organisms have options when facing change: they can do nothing, move, or adapt. These responses shape an organism's niche (a foundational concept in biology) that is abiotically constrained, but modified by biotic interactions. The greatest disturbances in recent North American geologic history is the human mediated extinction of megafauna ~11,700 years B.P. and climate change following the last glacial period. We used the fossil record to address ecological questions concerning conservationists; our focus was on Canidae and humans. Species distribution …

"In terms of volume and potential impact, the most serious conservation problem in the world today is the destruction of lowland tropical forests and the extinction of their fauna. Since 1950, according to the Food and Agriculture Organization, half of the world's forests have vanished (Cultural Survival, Inc., 1982). The conversion rate of these forests is currently so great that a recent National Research Council (1980a) panel has predicted that their existence as a natural ecosystem will cease by the year 2000, except perhaps in two areas - Western Amazonia and Central Africa. One important step toward the preservation of …
