From elizabeth_krone at fws.gov Wed Sep 4 16:37:52 2024 From: elizabeth_krone at fws.gov (Krone, Elizabeth C) Date: Wed, 4 Sep 2024 21:37:52 +0000 Subject: [APWG] SAVE THE DATE & RSVP: Plant Conservation Alliance e-Meeting, September 11, 2024, 2-4pm ET, with speaker Wendy Hodgson Message-ID: ***SAVE THE DATE*** Please RSVP to attend our fifth PCA meeting of 2024 where we welcome Wendy Hodgson, Herbarium Curator Emerita, Senior Research Botanist, Desert Botanical Garden, who will discuss ?Grand Canyon ? more than stunning geology, vistas and strange squirrels ? her Green Heart, the unsung legacy of plants.? ABOUT THE PRESENTATION: Studying plants and plant communities within the vast Canyon is no walk in the park so to speak. It is extremely challenging, facing an array of obstacles rarely experienced. Even more than grit and determination, studying the Canyon?s plants requires extensive collaboration involving the Park Service, Indigenous Peoples, outside researchers and community scientists, continually building on the work of previous intrepid plant explorers. Wendy will share reasons for the great diversity in the Canyon, introduce a few of its intriguing botanists that braved wild white water and steep cliffs to gather specimens, and spotlight some likewise charismatic plants. She will also highlight collaborative work that has continued for years as well as new, exciting projects, all of whose goals are to better understand what occurs where, including identifying and mitigating threats to rare species, the quest to identify new taxa, understanding how certain plants evolved and dispersed in the Grand Canyon and the Canyon?s role as an important genetic reservoir and refugia. And of course, how to get the public to wonder what plants occur down there. ABOUT OUR PRESENTER: Wendy Hodgson has lived in the Sonoran Desert for 55 years. She holds a B.S. in wildlife biology and an M.S. in botany from Arizona State University. This year Wendy celebrated 50 years of working at the Desert Botanical Garden in Phoenix, having started in 1974 as an assistant to famed agave expert Dr. Howard S. Gentry. Today she is the Herbarium Curator Emerita and Senior Research Botanist. Her research focuses on the Agave family, particularly the systematics and role of agaves, yuccas and Hesperoyucca in pre- and post-contact cultures. Wendy also focuses on Southwest floristics with a special emphasis on the Grand Canyon, where for 35 years she has searched for plants. She has authored or co-authored nine species new to science, including three from Grand Canyon. Wendy also focuses on Sonoran Desert food plants, publishing Food Plants of the Sonoran Desert, winner of the Klinger Book Award presented by the Society for Ethnobotany. She is an advocate for collaboration, working closely with numerous federal agencies, conservation groups, academia, community scientists and Indigenous Peoples in the study and conservation of plants and their habitat. This meeting is held remotely and open to all. More information about the presentation can be found on our PCA Meetings page. *** PLEASE RSVP TO ATTEND THIS MEETING *** RSVP by Tuesday, September 10, to elizabeth_krone at fws.gov The meeting login details will be shared with all respondents via calendar invite and email by Tuesday September 10.

Participants have shared countless stories about how information gained from their participation in this conference had a direct impact on the lands they steward. * The NAC provides science-based content for natural area practitioners and researchers seeking applied science, practical solutions, and knowledge transfer related to the management of natural areas on a day-to-day basis; such as land stewards in land trusts, nature centers, and nature preserves who manage land for their conservation or natural area values. * The NAC supports the conservation and the protection of biodiversity by providing access to quality science, new knowledge, best practices, and emerging methodologies for those who steward natural areas. Theme: Where Science Meets Stewardship Detailed agenda: https://www.naturalareas.org/detailed_agenda.php Fees/other: Full Registration until September 30: $649; One day, student, and late registration options available. Details & Registration: Registration is open through September 30; https://www.naturalareas.org/2024_natural_areas_conference.php Hosted by: Natural Areas Association; https://naturalareas.org/ -------------- next part -------------- An HTML attachment was scrubbed...

Britton, an annual plant in the mint family, is considered invasive in the United States where it excludes native vegetation in natural areas and can cause respiratory illness in livestock. An effective biological control agent would improve perilla management, but none have been developed or proposed. This study investigated the biocontrol potential of a fungal pathogen, Colletotrichum shisoi, recently found infecting perilla in North America. The growth rates and morphology of seven Colletotrichum shisoi isolates were recorded. A virulence assay was performed on two perilla accessions, and the number and size of foliar lesions produced were used to select a single isolate, Colletotrichum shisoi isolate 21-072, exhibiting consistently high virulence for further evaluation of biocontrol efficacy and host specificity. Treatment with 0.5?mL of 1???107 spores/mL H2O caused a 52% reduction in shoot height and 84% reduction in root length of invasive perilla seedlings compared to a control treatment (P?50% plant mortality from 48 to 24?h, but oil emulsions exhibited a mild phytotoxic effect on seedlings. Four additional perilla accessions were susceptible to C. shisoi, and none of 34 other species included in host range experiments developed disease symptoms following inoculation. These results suggest C. shisoi 21-072 could be an effective antagonist of perilla and likely poses a low risk of non-target impacts. * -- This email has been checked for viruses by Avast antivirus software. www.avast.com -------------- next part -------------- An HTML attachment was scrubbed...
