Summary
Abstract: This atlas displays the distribution of modern pollen abundances in
North America, both geographically and relative to various climatic,
bioclimatic, and vegetational variables. It is intended to aid analyses
of modern pollen-environment relationships as well as the climatic and
ecological interpretations of fossil pollen diagrams. The atlas is based
upon a recent compilation of pollen samples from surface sediments and
polsters that includes 4549 samples, 134 pollen types, and independent
climatic and vegetational attributes for all locations. Atlas pages are
presented for 106 pollen types, representing all of the major and many
minor pollen types found in North America. Ten pollen types are split
into eastern and western regional groups, using the corresponding
species range maps as a guide. The pages are designed to show in detail
the distribution of pollen abundances with respect to key climatic and
vegetational variables; each set includes a map of modern pollen abundances
plus a series of visualizations of pollen-climate and pollen-vegetation
relationships. The relationship between pollen abundances and indices of
fractional broadleaf and needleleaf areal cover is consistent with the
ecological associations of the plant taxon, and biomes can be distinguished
by the characteristic frequencies of various pollen abundances, although
abundances for individual taxa may vary widely within a given biome.
Pollen-abundance distributions with respect to environmental gradients
are usually characterized by an upper-limit unimodal distribution,
except where the representation of multiple species by a single pollen
morphological type results in multimodal distributions. Consequently,
high pollen abundances are usually more climatically informative than
low pollen abundances. Although individual pollen types are rarely
diagnostic of a particular climatic regime or vegetation type,
assemblage-level information about the abundances of many pollen types
provides a strong basis for paleoenvironmental inference.
