Carlos Rivera [email protected] Co-Authors Esteban Galeano, Theodor Leininger, Emile Gardiner Abstract (Include Poster Title) Title: Molecular Archiving of Stoneville and Other Eastern Cottonwood Clones Abstract: The current high demand for eastern cottonwood (Populus deltoides) (Fig. 1) in carbon fixation and biofuel production applications has raised the necessity to genotype and archive the Stoneville (ST) clones, which are used worldwide. In Spring 2024, we will collect fresh leaves of 100 ST clones and 300 additional individuals from trials in Mississippi, Alabama, and Tennessee. DNA will be extracted from leaves and genotyped. We will perform fingerprinting and estimate genetic diversity for each clone with the most informative SNPs. Finally, we will upload the information to a public repository.

Quentin Boccaleri [email protected] Co-Authors Krishna Poudel, Courtney Siegert, Adam Polinko Abstract (Include Poster Title) Optimized Site Selection for Short Rotation Woody Crop Systems in the Lower Mississippi Alluvial Valley. The advent of the carbon market along with demands for bioenergy has created expanding opportunities for Short Rotation Woody Crop (SRWC) systems. In the Lower Mississippi Alluvial Valley (LMAV), opportunities for landowners manifest as afforestation projects for Populus deltoides and Salix nigra on marginal agricultural sites.These pioneer species thrive on alluvial sites and have strong genetic improvement. This makes them the best candidates for SRWC plantations in the region. This project seeks to develop a spatial process-based 3PG (Physiological Processes Predicting Growth) model for both species and conduct simulations across the LMAV based on a variety of silvicultural and site inputs. Biomass yield from this model will be used to develop an economic analysis to determine the viability of the site for afforestation in the context of pervious agricultural yield. This poster will detail the proposal of this thesis project, including methods and expected results. Submitted Files 341158637183902324_qb_srwc_posterv2.pdf |

Emily White [email protected] Co-Authors Courtney Siegert, Joshua Granger, Cade Booth, Drew Williams Abstract (Include Poster Title) Carbon Sequestration Potential of Non-Commercial Tree Species in the Southeast Landowner participation in carbon exchange markets has become increasingly popular in the southeastern U.S. Advances in the knowledge of species-specific carbon storage are critical for development of accurate carbon quantification. Woody debris is a major component of the global carbon cycle, and the decomposition of wood is affected by the quality of substrate, climate, and the type and abundance of decomposer organisms. However, variation among tree species is a major factor affecting decomposition and long-term carbon storage that is not well known. To address this knowledge gap, a field experiment was initiated in 2021 to test the decomposition rates across several common, but silviculturally unimportant, species that exist on the landscape, with the goal of identifying species with desirable traits to facilitate long term carbon storage. Preliminary analysis found that wood density could be an indicator of sequestered carbon. After testing of time zero, six month, and twelve month data, the species with the highest total mass loss on average across all three sites was Red maple (29.8%) closely followed by Sweetgum (28.6%). Osage orange had the least mass loss with an average of only 6.2% after 12 months across all three sites. White oak had the highest percent density loss after six months (15.0%) however, had one of the lowest amounts of total mass loss on average after 12 months (11.8%). Preliminary data suggests that Loblolly pine has the highest portion of carbon composition (51.5%) however Osage orange has the greatest sequestration potential because it releases carbon the slowest (0.89%/6mo).
