Assessing the reliability of salinity inference models from diatom assemblages: an examination of a 219-lake data set from western North America

Abstract: Surface-sediment samples for diatom analyses, along with water chemistry and other limnological data, were collected from 113 fresh and saline lakes on the southern Interior Plateau and in the southern Rocky Mountain Trench of British Columbia, and combined with an existing calibration data set of 102 lakes from the southern interior of British Columbia and 11 saline lakes from the northern Great Plains. Diatom-based salinity inference models (= transfer functions) were developed using weighted-averaging and w… Show more

“…There was no statistical relationship between counting intensity and species richness. Past lakewater salinity was estimated from changes in the relative abundance of fossil diatoms using inference models that relate diatom species composition to modern lake chemistry (Wilson et al 1996). The predictive ability of these diatom-inference models is strong and highly significant, as judged from the relationship between inferred and observed salinity in a suite of modern lakes (bootstrapped r 2 ϭ 0.8-0.9, p Ͻ 0.001; Fritz et al 1999).…”

“…Given this general paucity of information, ecologists have recently adopted a quantitative approach to ecological reconstruction (e.g. Imbrie and Kipp, 1971;Nelson and Kashima, 1993;Hemphill-Haley, 1995a, b, c;Jones and Juggins, 1995;Wilson, et al, 1995;Gasse et al, 1997;Sherrod, 1999;Zong et al, 2001;Sawai, et al, 2004a, b). In coastal studies, the transfer function approach is producing a new generation of high-resolution sea-level reconstructions that is seeking to bridge the gap between shortterm instrumental records and long-term, traditional geological reconstructions or geophysical predictions (e.g.…”

“…Samples were freeze-dried and prepared according to standard procedures (Batterbee, 1986;Wilson et al, 1996). All diatoms were identified to the lowest possible taxonomic level and taxonomy following Krammer andLange-Bertalot (1986-1991), Germain (1981) and Schrader and Gersonde (1978).…”
