Abstract

Southern conifers have evolved under different evolutionary pressures compared with northern lineages, but in both regions these plants have undergone extensive extinction and range alteration over the Cenozoic (the last 66 Myr). It is not possible to observe the ecology of fossils directly, but indirect evidence of changes in bioclimatic envelopes can be derived from no-analogue assemblages (i.e., groups of co-occurring fossils that have climatically incongruous living relatives). We identify and examine the specific pairs of no-analogue fossils within assemblages to disentangle the effects of climatic factors on past conifer extinctions and suggest which of these factors are likely to threaten southern conifer biodiversity in the future.
