Stomatal Differences In Western Aspen And Linkage To Drought Tolerance, Brianne Palmer
Stomatal Differences In Western Aspen And Linkage To Drought Tolerance, Brianne Palmer
Undergraduate Honors Capstone Projects
Aspen (Populus tremuloides) is the most widely distributed broadleaf forest tree in North America. However, aspen are declining rapidly in areas of the Intermountain West. Aspen in this area are prone to experiencing limited moisture and high temperatures. An important aspect of plant physiology when dealing with these stressors is stomatal function. Stomata control the rate of photosynthesis, therefore, the size and frequency of the stomata is likely to influence the survival of the species in this environment.
An unusual feature of aspen is the high frequency of triploidy in the southern portion of its range. Stomata! size …

Biodiversity Prioritization: A Comparison Of Data Types, Kari Norman
Undergraduate Honors Capstone Projects
The identification of important areas for biodiversity is essential for effective allocation of limited conservation resources. Prioritizing regions for conservation based on biodiversity is typically done using global biodiversity maps created using range map data for one or more taxa. While the use of range maps makes pragmatic sense since large-scale survey data is rarely available, it is important to understand the sensitivity of the results to the use of range map data. We studied how prioritizations may change between data types using the North American Breeding Bird survey (BBS) and BirdLife International range maps as a comparison case study. …
