Item Building maps of plant surface chemistry using literature and citizen-collected mass spectrometry samples(2022-06) Nguyen, Dien LeUnderstanding plant chemicals can greatly help achieve the important goals of reducing negative environmental impacts of agriculture and achieving high crop yields. One class of chemicals that has a big influence on plant health and growth is triterpenoid. However, there is a limited number of biological systems in which to study triterpenoids in detail. To increase the number of study systems, and thus our potential to build knowledge of triterpenoid function, there is a critical need to understand which triterpenoids can be found on which plant species' surface. The objective of this project was to build maps of plant surface compound presence with an emphasis on triterpenoids, using published and newly acquired gas chromatography-mass spectrometry data. The maps reveal trends that some triterpenoids are very commonly found on plant surface, while others are rare. In addition, divergent and convergent evolution traits among plants regarding their triterpenoid and other wax compounds presence were also identified.Item Fruit Herbivory on Individual Plants in Long-Term Study of Population Dynamics of Clarkia xantiana ssp. xantiana at 26 sites in the Kern River Valley, California, USA from 2001 to 2015(2017-07-28) Moeller, David; Geber, Monica A; Eckhart, Vince M; moeller@umn.edu; Moeller, DavidDocumentation of fruit herbivory on individual plants in long-term study of population dynamics of Clarkia xantiana ssp. xantiana at 26 sites in the Kern River Valley, California, USA from 2001 to 2015.Item Fruiting Plant Number in Long-term Study of Population Dynamics of Clarkia xantiana ssp. xantiana at 35 Populations in the Kern River Valley, California, USA from 2006 to 2017(2017-07-25) Moeller, David; Geber, Monica A; Eckhart, Vince M; moeller@umn.edu; Moeller, DavidDocumentation of data collected on fruiting plant number per 0.5m2 in long-term study of population dynamics of Clarkia xantiana ssp. xantiana at 35 populations in the Kern River Valley, California, USA from 2006 to 2017Item Perceptions of Invasive Species and Their Control Among the MN Tourism Industry(University of Minnesota Tourism Center, 2014) Schneider, Ingrid E.; Qian, XinyiThis project sought baseline information on perceptions of invasive species and theie control among the Minnesota tourism industry. The majority of respondents agreed that both invasive plant & aquatic invasives were harmful to Minnesota’s environment, economy & society. Similarly, the majority of respondents indicated all 7 control methods presented in the questionnaire would be effective to control invasive species.Item Site Characteristics and Climate in Long-Term Study of Population Dynamics of Clarkia xantiana ssp. xantiana at 35 Sites in the Kern River Valley, California, USA from 2006 to 2017(2017-07-25) Moeller, David A; Geber, Monica A; Eckhart, Vince M; moeller@umn.edu; Moeller, David ASite locations and environmental variables of 35 populations of Clarkia xantiana ssp. xantiana where plant density and fruit production have been measured in a long term demographic study.
