    Unique responses to climate change can occur across intraspecific levels, resulting in individualistic adaptation or movement patterns among populations within a given species. Thus, the need to model potential responses among genetically distinct populations within a species is increasingly recognized. However, predictive models of future distributions are regularly fit at the species level Cited by: 8. Reticulate evolution and incomplete lineage sorting among the ponderosa pines. G. Bucci, M.

A recent study using mitochondrial DNA analysis demonstrated substantial genetic variation among ponderosa pine populations in the western U.S., identifying 10 haplotypes with unique evolutionary lineages that generally correspond spatially with distributions of the Pacific (P. p. var. ponderosa) and Rocky Mountain (P. p. var. scopulorum Cited by:

Most ponderosa pines in northwestern and western Nevada have long needles (13–25 cm), in fascicles of 3 needles, as do those on the west slope of the Sierra Nevada and along the Pacific Coast of : David Alan Charlet.

Jeffrey pine has a much smaller geographic and ecological range than does ponderosa pine being confined to Baja California, California and the Siskiyou Mountains of Oregon.

Native ponderosa pines encounter and hybridize with other western yellow pines (P jeffreyi Grev. & Balf., P.

nigra x P. resinosaCited by:   The Jeffrey pine (Pinus jeffreyi) and the ponderosa pine (Pinus pinderosa) look very similar. Once these two trees were classified as the same species or some botanists considered the Jeffrey pine a variety of the ponderosa pine.

To further confuse the situation the ponderosa and Jeffrey pines occasionally hybridize. For the plant community that is dominated by this tree, see Ponderosa pine forest. "Ponderosa pines" redirects here. For the place, see Ponderosa Pines, : Drjbh. Ceographic Variation in Ponderosa Pine I.

Sugar pines grow to heights of feet tall with diameters of up to 10 feet and are second only to giant sequoias in their total volume of wood.
