Center for Tree Science Strategy (3.67061)
Date: 2014Type: Document
Description:Around the world, trees are under threat in the wild and in urban areas. Only concerted effort can preserve tree diversity, urban forests, and the many benefits they provide to people and the environment. But those efforts are hampered by a lack of scientific understanding of the complex challenges faced by trees and forests and by a diminishing pool of people trained to meet those challenges. The Center for Tree Science at The Morton Arboretum catalyzes scholarship and training for the future of trees and people.

Effects of climate on the growth response and anatomical tradeoffs of red and white oak (3.85993)
Date: August 16 2019Creator: Rollinson, Christine R.
Type: Document
Description:Poster presented by Jessica Oros, Ross Alexander, and Christy Rollinson at the Ecological Society of America Conference on August 16, 2019.
Overview: Oak, a ring porous genus, grows hollow xylem structures (vessels) for transporting water. Different species of oak, such as Quercus alba and Quercus rubra, may show variations in earlywood vessel size and density. We asked the question, “Do climate and management impact tradeoffs in vessel growth in these two species of oak?”

Forecasting tree phenology and climate vulnerability by leveraging botanic garden collections and citizen science observations (3.85994)
Date: August 13 2019Creator: Rollinson, Christine R., Zumwalde, Bethany , Reidy, Brendon
Type: Document
Description:Poster presented by Christine R. Rollinson, Bethany A. Zumwalde, and Brendon Reidy at the Ecological Society of America Conference on August 13, 2019.
Overview: Phenology has been widely used as a bioindicator of potential tree responses to climate change. Additionally, past studies have successfully modeled species distributions based on phenology because plants are unlikely to persist in a location if they are at high risk of freeze damage to leaves, flowers, or fruits. Large citizen science networks such as the USA National Phenology Network have increased the spatial distribution observations for many tree species, but are unable to robustly capture rare or threatened species having restricted or climate-sensitive distributions. Botanic gardens and arboreta help fill this gap by growing diverse arrays of species, often emphasizing preservation of rare species through taxonomically or geographically oriented collections. At The Morton Arboretum, we are combining phenology observations of tree species both in and outside of their natural habitats through volunteer and national citizen science efforts in order to better determine climatic constraints on tree species distributions. In 2017, we began to pilot these concepts through analyses of the genus Quercus (oaks) as one of the most broadly distributed and ecologically important taxa across the globe.
In 2017, we monitored leaf and reproductive phenology for 64 trees from 29 species of Quercus, which was then expanded to 234 trees representing 58 species in 2018. Due to a mild winter in 2017, the onset of budburst was nearly 3 weeks earlier in 2017 than in 2018, although the dates of peak fall color were similar across years. In both years, species showed a narrower range for date of first budburst than for peak fall color, suggesting more consistent cues for start of growing season in temperate deciduous oaks than for the end of season. In the future, we will use the phenological covariance among co-occurring or phylogenetically related species in botanic gardens and the USA National Phenology Network to better assess climate sensitivity and potential vulnerability of species of concern.

Proposed species extinction target fails to capture the diversity in biodiversity (3.86484)
Date: August 13 2020Creator: Hoban, Sean M.
Type: Document
Description:An eLetter response to the Science article: Rounsevell, M.D.A., Harfoot, M., Harrison, P.A., Newbold, T., Gregory, R.D. & Mace, G.M. "A biodiversity target based on species extinctions." Science 368, no. 6496 (2020) : 1193-1195.
The eLetter points out that a headline global biodiversity conservation target on species extinctions has numerous defects: a negative rather than positive outlook, inability to measure on realistic timeframes, inequity across countries, past historical failures, and neglect of other components of biodiversity (traits, genes, ecosystems, functions, services).
Grafting has enormous ex-situ conservation potential (3.86485)
Date: August 25 2020Creator: Cannon, Charles H., Kua, Chai-Shian
Type: Document
Description:An eLetter response to the Science article: McCann, M.C. "Chimeric plants--the best of both worlds." Science 369, no. 6504 (2020): 618-619.
This online letter to the editor argues that grafting, a unique property of plant propagation, is an exciting and potentially powerful way to preserve, manage, and explore plant biodiversity.
