Preparing For The Worst: Enhancing Seedling Traits To Reduce Transplant Shock In Semi-Arid Regions, Douglas Evan Mainhart, Bradley O. Christoffersen, R. Alexander Thompson, Charlotte M. Reemts, Alejandro Fierro-Cabo

School of Integrative Biological & Chemical Sciences Faculty Publications

The spatial extent of semi-arid hot regions is forecasted to grow through the twenty-first century, complicating restoration and reforestation plans. In arid and semi-arid climates, seedlings are more susceptible to transplant shock due to lower soil moisture throughout the year. Determining strategies to reduce seedling stress and improve survival post-planting will be paramount to continued reforestation efforts in a changing climate. We quantified seedling physiological, morphological, and field performance (mortality and growth) response for five species native to the semi-arid region of South Texas (Erythrina herbacea L., Celtis pallida Torr., Fraxinus berlandieriana DC, Malpighia glabra L., and Citharexylum berlandieri B.L …

Nursery Cultural Practices Influence Morphological And Physiological Aspen Seedling Traits: Implications For Post-Fire Restoration, Aalap Dixit, Owen Burney

Aspen Bibliography

Aspen forests are threatened by the impacts of a changing climate and are showing large-scale mortality with meager natural regeneration to restore these loses. Therefore, there is an increasing demand for high-quality aspen seedlings to assist with forest restoration efforts. Nursery cultural practices can be used to alter aspen seedling traits to improve adaptability to dry planting conditions. In this study, the effects of container size (SC10 and D30; 158 and 590 mL, respectively) and nursery irrigation treatment (high and low irrigation; 90% and 70% container capacity, respectively) on seedling growth and a suite of morphological and physiological traits were …

Exploring The Multifunctional Landscapes Model In Areas Dominated By Non-Native Tree Plantations, Andrea Monica D. Ortiz, Eugenia M. Gayó, Noelia Carrasco Henríquez, Bárbara Jerez Henríquez, Aníbal Pauchard

SOSE Affiliate: Manila Observatory

Multifunctional landscapes offer an integrated approach to production, conservation, and human well-being. However, the challenges of implementing them in territories where plantations dominate are yet not well understood. This is the case in Chile, where plantations of non-native pines and eucalypts are extensively planted in its South-Central regions for timber and pulp. The resulting landscape homogenization, environmental degradation, and increased wildfire risk have caused and exacerbated conflicts, impacting biodiversity and the well-being of local communities and the Indigenous Mapuche Peoples. After the mega-wildfires in the region in 2023, science-policy discourse promoted the multifunctional landscapes model as a way to increase …

Cascading Effects Of Assumption Violations In An Extension Program Development Model, Susan T. Guynn, Patrick Hiesl, Shari L. Rodriguez, Janet Steele

Journal of Human Sciences and Extension

The Cooperative Extension Service delivers informal educational programs that can help to improve the lives of citizens and communities. Planning, design, implementation, and evaluation are crucial considerations for Extension programs and serve as the foundation for the Extension Program Development Model. The Extension Program Development Model has underlying assumptions that may not be explicitly stated or apparent to Extension practitioners, but if the assumptions are violated, it can lead to cascading effects that impact the effectiveness of an Extension program. This paper will discuss the assumptions of the Extension Program Development Model and the potential impacts of assumption violations. We …

Barriers To Implementation Of California Vegetation Treatment Program Projects, Jacquelyn Morales

Master of Science in Environmental Sciences and Management Projects

To better defend wild lands within California's state responsibility areas against wildfire, progress toward efficient fuels management is vital. Created in effort to increase pace and scale of forest fuels reduction, the California Vegetation Treatment Program (CalVTP) serves as method to expedite fire fuel reduction, fuel break development, and ecological restoration projects by streamlining environmental regulatory approval. To better assess the progress of fuels management projects across the state, this professional project aims to look at barriers faced by project proponents when using the CalVTP. A questionnaire was emailed to the project proponents behind the 81 unique CalVTP projects in-progress. …

Forest Defoliation By And Invasive Outbreak Insect: Catastrophic Consequences For A Charismatic Mega Moth, Richard L. Lindroth, Mark R. Zierden, Clay J. Morrow, Patricia C. Fernandez

Aspen Bibliography

Earth is now experiencing declines in insect abundance and diversity unparalleled in human history. The drivers underlying those declines are many, complex, and incompletely known. Here, using a natural experiment, we report the first test of the hypothesis that forest defoliation by an invasive outbreak insect compromises the fitness of a native insect via damage-induced increases in toxicity of the forest canopy. We demonstrate that defoliation by the invasive spongy moth (Lymantria dispar) elicits an average 8.4-fold increase in foliar defense expression among aspen (Populus tremuloides) genotypes. In turn, elevated defense dramatically reduces survivorship, feeding, and …

Simulating The Long-Term Response Of Forest Succession To Climate Change In The Boreal Forest Of Northern Ontario, Canada, Guy R. Larocque, F. Wayne Bell, Eric B. Searle, Stephen J. Mayor, Thomas Schiks, Parvin Kalantari

Aspen Bibliography

The effect of climate change on forest dynamics is likely to increase in importance in the forthcoming decades. For this reason, it is essential to predict the extent to which changes in temperature, precipitation, and atmospheric CO₂ might affect the development of forest ecosystems and successional pathways. The gap model ZELIG-CFS was used to simulate the potential long-term effects of climate change on species-specific annual change in mean basal area and stand density under two scenarios of representative concentration pathways (RCP), 4.5 and 8.5, for the boreal forest region of Ontario, Canada, where mean temperature, precipitation, and atmospheric CO …

Chinese Tallow Long-Term Impact On Stand Dynamics In A Bottomland Hardwood Forest Following Vegetation Management, Nicklaus R. Langlois

Electronic Theses and Dissertations

Chinese tallow (Triadica sebifera (L.) Small) is an invasive tree known to have negative impacts on bottomland hardwood forests. Chinese tallow is proficient in reproducing and surviving in bottomland hardwood forests because it is more flood and shade tolerant than most native trees. The long-term effectiveness of Chinese tallow control is an important topic to research as only a few long-term studies of Chinese tallow control have been conducted. A 10-year re-measurement of 22 paired plots installed in 2012 on the Pineywoods Mitigation Bank near Diboll, Texas following herbicide treatments examined Chinese tallow and native tree stand structure. Each …

Investigation Of Using Natural Deep Eutectic Solvents (Nades) For Extraction Of Bioactive Compounds From Aronia Melanocarpa Fruit, Melek Zor

Turkish Journal of Agriculture and Forestry

In this study, for the extraction of polyphenolic compounds found in high amounts in aronia fruit, three different extraction methods (classical, ultrasound, ultrasonic), three different traditional solvents (water, ethanol, acidified 80% methanol) as well as five different natural deep eutectic solvents (NADES) were used. Color indices as L*, a*, b*, C* and H° values, total phenolic, total flavonoid, total monomeric anthocyanin, total antioxidant capacity (DPPH, ABTS and FRAP assays) and phenolic compounds of aronia fruit extracts were analyzed. There were significant differences in the measured parameters depending on the extraction method and solvent type. Extracts in ultrasound extraction and classical …
