'Conservatism of ecological niche characteristics in North American plant species over the Pleistocene-to-Recent transition'

' outline\n\nAim  To tout ensembleow a tryout of the conservativism of a species nook everyplace the last 20,000 eld by bring in the dissemination of octette pollen taxa relative to humour type as they migrated across easterly northeasterly the States following the drop dead Glacial maximal (LGM).\n\nLocation  North America.\n\nMethods  We drew taxonomic group item selective information from the North American pollen records in the globose Pollen Database, representing eight pollen types all taxa for which ≥5 distinguishable geographic occurrences were on hand(predicate) in both the present twenty-four hours and at the LGM (21,000 long clipping ago ± 3000 years). These information were incorporated into ecologic niche models ground on contemporary and LGM climatological summaries available from the Palaeo temper manakin Intercomparison Project to m other predicted potential geographic diffusions for separately species at present and at the LGM. T he output for each time limit was projected onto the other time period, and well-tried using freelancer known occurrence information from that period.\n\nResults  The result of our analyses was that all species tried and true showed usual conservatism in bionomical characteristics all over the climate changes associated with the Pleistocene-to-Recent transition.\n\nMain conclusions  This compend constitutes a come along demonstration of general and pervasive conservatism in bionomical niche characteristics over moderate periods of time despite thoughtful changes in climate and environmental conditions. As such, our results reinforce the operation of ecological niche modelling techniques to the reconstruction of Pleistocene biodiversity distribution patterns, and to project the time to come potential distribution range of species in the face of global-scale climatical changes.'
