Project Progress: 

• Ash Hamilton, PhD student at the University of Chicago, led an international team of scientists (including Gavin Salas, the lab’s RAMP fellow) on a 10 day field work trip in Baja California Sur, Mexico. This fieldwork is a crucial part of Ash’s dissertation work on effective population size through time on the endangered, endemic Quercus brandegeei. This trip involved the group monitoring selected trees at several sites, collecting more than 1300 acorns in total from these trees, and prepping pots, soil, and nursery space to plant a select 1200 of the collected acorns at a local nursery. When these acorns grow into seedlings, they will be sampled by Ash for genetic analyses and then adopted out to local community members as a part of a conservation program “¡Salvemos el encino arroyero!” led by the Morton Arboretum and a regional governmental agency in Mexico (CIBNOR) [link to CIBNOR].

Outreach and Training

• Sean Hoban, Tree Conservation Biologist, led a consortium of scientists worldwide to create support materials for policy makers at a recent scientific and technical meeting of the Parties to the Convention on Biological Diversity, held in Nairobi Kenya in October. The team created a policy brief translated in four languages, a short video, a flyer, and a post for an online CBD discussion forum. The materials were presented on an easy to read website. This builds on the engagement and support the team provided at the Kunming Montreal Global Biodiversity meetings in December 2022. The goal of the materials was to explain the recent implementation of genetic diversity indicators in a fast, affordable manner in nine countries, including four megadiverse countries. One message highlighted was that many populations worldwide may be on the precipice of large losses of genetic diversity, and that this status of biodiversity can be monitored in all countries, without the need for DNA sequencing data.

Events and Presentations

• Sean Hoban, Tree Conservation Biologist, presented a seminar virtually at the University of Connecticut on November 17 to approximately 15 students and faculty.

• Castilla, A.R., Brown, A., Hoban, S., Abhainn, E.A., Robinson, J.D., Romero‐Severson, J., Smith, A.B.,Strand, A.E., Tipton, J.R. and Dawson, A., 2023. Integrative demographic modelling reduces uncertainty in estimated rates of species' historical range shifts. Journal of Biogeography. OPEN ACCESS
  • This publication from several current or former Morton employees (Hoban, Brown) and CTS Fellows (Strand, Castilla) was the capstone of an NSF project to improve methods in biogeography- the study of species’ ranges and how they change over time. The paper showed that it is possible to integrate ecological niche models, pollen fossil data, and genetic data to better understand how fast tree species (specifically, Fraxinus pennsylvanica, green ash) migrated north after the last Ice Age. The paper also provides hints about how fast species may respond to modern climate change, and provides open source code for the methods for others to use. This project team’s work was originally sparked by CTS seed funding to bring the researchers together to meet in 2017.
• Carroll, C., Hoban, S. and Ray, J.C., 2023. Lessons from COP15 on effective scientific engagement in biodiversity policy processes. Conservation Biology. OPEN ACCESS
  • This publication provides a perspective and review of the advancement of science-based policy in the Convention on Biological Diversity.  The authors write about the challenges and opportunities of expanding the idea of conservation beyond just conserving species to conserving both genes and ecosystems. The article touches on efforts to conserve 30 percent of ecosystems by 2030, and efforts to measure and manage genetic diversity affordably and quickly. Challenges included explanation of definitions, the speed and complexity of policy negotiations, science communication, and incentives and guidance for scientists to engage.

Events and Presentations:
​

• Members from the Global Tree Conservation Program (Silvia, Kate and Victor) and the Conservation Biology group (Emily, Austin and Gavin) attended the Rare Plant Research and Mentoring Program (RAMP) Annual Symposium in Atlanta Botanic Garden. During this meeting, Research Aides Victor García and Gavin Salas presented an update on their research and participated in multiple career development workshops and activities. This activity is part of the NSF-funded Rare Plant RAMP Project. Next year’s symposium will be hosted at Morton Arboretum.  
  
  
• Sean Hoban presented a seminar at University of Toronto October 6. He also spent the day meeting about 15 graduate students and postdocs in the department. The audience for the seminar was about 30 students and professors. Sean also presented a seminar virtually at the University of Memphis on October 19 and met 6 students and postdocs to discuss their work.
• Sean Hoban attended the GEO BON (Group on Earth Observation Biodiversity Observation Network) meeting “Monitoring Biodiversity for Action,” in Montreal, Canada. This meeting brought together many kinds of scientists in biodiversity monitoring, reporting, and policy- from eDNA, to satellites, to community based monitoring. At the conference Sean networked with representatives from IUCN, GBIF, BGCI, the Quebec biodiversity center, and the Forest People’s Program. Sean also gave a talk titled “Assessing genetic diversity in the absence of genetic data, using indicators” to an audience of about 30.

We had two new members join the Hoban lab this month: Mikaely Evans, a rising junior at Macalaster College, started her time in the Hoban lab as a NSF REU; and Samarth Mohan, a rising high school junior, started working as a volunteer. Very exciting news and welcome to them both!

Additionally, Emily Schumacher was promoted to the Tree Conservation Biology Lab Manager in the lab. ​In her new role, Emily will work closely with the lab scientist in planning new methodologies and initiatives to continue to grow the Tree Conservation Biology program and increase her role in managing budgets and grant reporting. With Emily’s guidance, the program will seek ways to more effectively research and disseminate knowledge on tree conservation biology, mentor future plant conservationists, and manage a complex set of strategic partnerships including NSF, IMLS, USGS, IUCN, the US Botanic Garden and US Forest Service.

  • This paper describes a project underway to apply indicators of genetic diversity conservation which are affordable and simple, in nine countries around the world. We address concerns of policy makers and implementation challenges, and describe a roadmap for further development and deployment, incorporating feedback from a broad community. We demonstrate that countries can successfully and cost-effectively report the status of species’ genetic diversity and adaptive capacity with existing biodiversity observation data, and, in doing so, better conserve the Earth's biodiversity.

Outreach: 

• ​​Sean Hoban, Tree Conservation biologist has been invited to join the Whitebark Pine Recovery Plan Genetics Working Group.  This team, led by the US Fish and Wildlife Service, is advising on writing a Recovery Plan for whitebark pine (Pinus albicaulis), which was recently listed under the Endangered Species Act.  The recovery plan will have a goal of listing all activities needed to recover the species to the point it can be delisted.
