Emphasis on quality in iNaturalist plant collections enhances learning and research utility

Following the switch to remote online teaching in the wake of the COVID-19 pandemic, the plant taxonomy course at the University of Georgia (UGA) switched to iNaturalist for the specimen collection portion of the course requirements. Building off extant rubrics, the instructors designed project guidelines for a fully online plant collection experience to alleviate plant awareness disparity. Researchers collected stratified samples from the UGA iNaturalist project along with four other institutions projects to determine if rubrics and project guidelines could improve the quality of observations to make them useful in plant science research. The specific rubric was shown to improve quality of iNaturalist observations. Researchers found that iNaturalist increased engagement as a student-centered tool but did not enhance their manual keying skills as the app uses automatic identification. Instructors recommend continuing to use iNaturalist to supplement physical collection and keying along with a detailed rubric and guidelines for collection.

Effect of soilless media on small-scale propagation of Pinguicula gigantea

Because of their large size, colorful flowers, and insectivorous habit, butterworts (genus Pinguicula) are desirable ornamental plants among hobbyists and botanical conservatories. Propagation via leaves is a popular propagation method for the genus, especially for tropical species. P. gigantea, a species found approximately 700m above sea level in Oaxaca, Mexico, was selected to evaluate its preference for various blends of soilless media. This study found that number of leaves produced by plantlets is significantly impacted by soil type. However, there was no significant difference in biomass, plantlet diameter or average number of plantlets produced between soil treatments. These results suggest that soils with high nitrogen content may promote increased leaf number, but do not significantly affect plant biomass.
