This study looks at Ocotillo (Fouqieria splendens) at the northern extent of its range in New Mexico. Gross morphological and phenological measurements are made in the field and leaves are collected for isozyme work. Questions that this study may address are: Do individuals at range edges show reduced genetic diversity relative to individuals in the heart of the range? Do population age structures(Can we age them?) differ at edges. Can we, in time, determine stasis or movement of populations? Are demographics germane to the study questions? What other methods, in addition to isozyme work will we use to get at the relative genetics of these populations?

Location: South Gate is the major entry point onto the southeast side of the Sevilleta NWR. Just north of the gate is Met Station 41. Research here has included a Gunnison's prairie dog reintroduction as well as re-sampling of historic BLM 1976 vegetation transects, and juniper-creosote distribution. Vegetation is highly impacted by historical cattle grazing and is sparse. Burro grass (Scleropogon brevifolius) is dominant.siteid: 11
