Some Biogeographers, Evolutionists and Ecologists:
Sears, Paul Bigelow (United States 1891-1990)
plant ecology, conservation
||Although not a prolific scientific writer, Sears spent
a good portion of his early years investigating the history of postglacial
vegetation in eastern North America. There he involved himself in studies
concerning archeology-fossil pollen relations, field and data recording
techniques, prairie enclaves in forested areas, climate changes, and biogeographic
relationships. He was especially known for his development of the techniques
of pollen analysis. More importantly, possibly, this background gave him
an appreciation for ecological change as affected by human beings, and
in the second half of his life he became known as one of the country's
leading conservationists and writers on environmental subjects. His 1935
book Deserts on the March was especially influential, stimulating
a greater national appreciation of the importance of soil conservation,
and focusing attention on the interplay between ecology and human activity.|
