Insights Into The Conservation Of The Rare Perennial Herb, Astragalus Applegatei, Sean Stewart
Cal Poly Humboldt theses and projects
As anthropogenic activities expand, conservation of rare and endangered species is critical to reduce extinction risks. Collecting and analyzing demographic data can assist in the development of conservation strategies and can help evaluate the success of existing strategies. In this study, I built integral projection models from five years of demographic data and conducted a population viability analysis on four populations of the rare perennial herb, Astragalus applegatei, to inform conservation decisions. I also assessed how planting A. applegatei seedlings might contribute to the growth of an extant population. I found that one population was already below the extinction …

The casual posting of a misidentified photograph led to a tweet exchange among Chris Martine, Bucknell University; Ryan Folk, Florida Museum of Natural History; and Scott Schuette, Pennsylvania Natural Heritage Program in June 2017. The scientists used their private accounts to conduct a discussion about the specific species identified. This exchange opened the possibility of a previously unknown range of a rare species, which Martine explored further and documented in the scientific publication PhytoKeys.

Taxonomic delimitation of rare species is vital for accurate assessments of diversity and for their conservation. Cycladenia humilis, the sole species of Cycladenia, is an enigmatic perennial widely dispersed across the western United States. Within this species there are three currently recognized varieties: C. humilis var. humilis in Northern California, C. humilis var. venusta in Southern California, and C. humilis var. jonesii in Utah and Northern Arizona. Some populations occur geographically in areas between the typical distribution of each variety and the presently accepted taxonomy inadequately addresses these populations. Using five nDNA regions, we seek to clarify relationships between current …
