网页2024年7月4日 · Worked example of how niche metrics were computed for three Pinus species, where we quantified niche widths as the distance between 0.01 and 0.99 quantiles for both realized occurrences (BIEN and Little’s range maps) and potential occurrences (a combination of realized occurrences plus arboreta occurrences). (J) …

网页2023年2月6日 · The lodgepole pine (Pinus contorta Dougl. ex Loud.) has probably the widest range of environmental tolerance of all conifers in Western North America. In its native range, it grows from the Pacific Coast to the Rocky Mountains from 64° N in Yukon Territory to 31° N in Baja California at elevations <3,900 m.
