LSU Doctoral Dissertations
In recent years, the rheological aspects of suspensions/emulsions applied by cellulose nanomaterials (CNMs) have been gained considerable interests due to high gel-forming properties ascribed by hydrophilicity, crystallinity, ease functionalization, and high aspect ratio. Introducing residual lignin in CNMs (LCNMs) seemed to be capable of achieving various advantages in the application of CNMs ascribed by hydrophobicity, binding effects, and abundant aromatic groups derived from complexity of lignin. This dissertation dedicates to the characterizations of (L)CNMs, and rheological properties of (L)CNMs applied fluids (i.e., suspension and emulsion). In the suspension system, the presence of lignin in LCNMs decreased gel strength, viscosity, and …

Contrasting Effects Of Climate Warming On Hosts And Parasitoids: Insights From Rocky Mountain Aspen Leaf Miners And Their Parasitoids, Alisha A. Shah, Emily Hamant, Juan G. Rubalcaba, Beau Larkin, Andrew A. Forbes, H. Arthur Woods
Aspen Bibliography
Because temperature has pervasive effects on biological rates, climate warming may alter the outcomes of interactions between insect hosts and their parasitoids, which, for many host species, constitute the single largest source of mortality. Despite growing interest in parasitoid-host responses due to climate change, there are few empirical tests of thermal tolerance differences between non-model lepidopteran hosts and their parasitoids and almost none from mountain ecosystems where warming is occurring more rapidly. We examined the thermal ecology of a host–parasitoid interaction in the Rocky Mountains using the wild populations of the aspen leaf miner (Phyllocnistis populiella) and a …

The extent of wildfires in tundra ecosystems has dramatically increased since the turn of the 21st century due to climate change and the resulting amplified Arctic warming. We simultaneously studied the recovery of vegetation, subsurface soil moisture, and active layer thickness (ALT) post-fire in the permafrost-underlain uplands of the Yukon-Kuskokwim Delta in southwestern Alaska to understand the interaction between these factors and their potential implications. We used a space-for-time substitution methodology with 2017 Landsat 8 imagery and synthetic aperture radar products, along with 2016 field data, to analyze tundra recovery trajectories in areas burned from 1953 to 2017. We found …

Bryce Canyon Aspen: Recent Trends, Future Actions, Paul C. Rogers
Aspen Bibliography
In cooperation with Bryce Canyon National Park, we undertook a survey of quaking aspen (Populus tremuloides Michx.) conditions throughout the Park with the intention of better understanding conditions and prescribing corrective measures where needed. There are clear disparities within the Park between sustainable aspen conditions and failing stands. Based on condition of mature trees, but most importantly regeneration and recruitment of juvenile stems, most aspen forests within Bryce Canyon are in poor condition. Aspen recruitment—generally sapling-sized trees that have survived browsing ungulates—is the most important metric of future stand resilience and here we found 83% of all aspen sample …

The former study suggests that Italian consumers are willing to pay premiums for new bio-based products but expect discounts on second-hand clothing, revealing a sustainability bias. This study adds more insights into such a bias by examining factors influencing consumers’ willingness to pay a premium for bio-based clothing and their expected discounts for second-hand items. Using Bayesian Mindsponge Framework (BMF) analytics on a dataset of 402 Italian consumers, the findings reveal that environmental concerns are positively associated with premiums for bio-based clothing, while higher income and education levels are also associated with the higher premium that consumers are willing to …

Edge Feathering Across Forest-Meadow Ecotones Increases Light Heterogeneity And Understory Plant Diversity, Aruni Kadawatha, Jean H. Burns
Faculty Scholarship
Ecotones, the transitional zones between distinct habitats, are vital for ecosystem functioning and habitat diversity. Traditional management practices frequently create abrupt boundaries, leading to stressful conditions for organisms. To address this challenge, an underutilized land management technique called “edge feathering”, which involves gradual thinning of the canopy along the forest edge, has been introduced. This study, con- ducted at Holden Arboretum in Kirtland, Ohio, investigated the effects of edge feathering on light availability and understory plant diversity in edge feathered and control treatments. We calculated the coefficient of variation in light availability as light heterogeneity and plant diversity indices at …

Changing Fire Regimes In The Great Basin Usa, Eva K. Strand, Kori Blankenship, Corey Gucker, Mark Brunson, Eugénie Montblanc
Aspen Bibliography
Wildfire is a natural disturbance in landscapes of the Western United States, but the effects and extents of fire are changing. Differences between historical and contemporary fire regimes can help identify reasons for observed changes in landscape composition. People living and working in the Great Basin, USA, are observing altered fire conditions, but spatial information about the degree and direction of change and departure from historical fire regimes is lacking. This study estimates how fire regimes have changed in the major Great Basin vegetation types over the past 60 years with comparisons to historical (pre-1900) fire regimes. We explore potential …

Monitoring And Modeling Legacy Tree Response To Restoration Treatments In The Klamath Mountains, Oregon, Usa, Isaac Joseph Ball
Dissertations and Theses
Climate change and its disruption of historical drought and wildfire patterns pose a substantial threat to forest health in the western United States. This threat is compounded by past management practices like fire suppression. The largest, oldest, and most ecologically valuable trees are particularly vulnerable, making their conservation a key objective of climate-adaptive forest management. Restoration treatments such as mechanical thinning have been shown to enhance tree growth and drought resilience in dry conifer forests, but long-term monitoring is necessary to understand their sustained effects. This study used dendroecological tree-ring analysis to investigate the effects of thinning on the growth, …

Occurrence Of Spotted Wing Drosophila (Drosophila Suzukii) In Wild Berries In Forested Areas Of Marquette And Keweenaw Counties, Upper Peninsula Of Michigan, Alexis M. Shatrau, Erika I. Hersch-Green
The Great Lakes Entomologist
Spotted-wing Drosophila (SWD, Drosophila suzukii Matsumura, Diptera: Drosophilidae) is an invasive fly that targets unripe soft-fruits causing premature ripening, dehiscence, and rotting. While the presence of SWD in agricultural systems is well-documented, much less is known about the host range of SWD in wild areas, especially in more northern latitudes where colder temperatures and short summers are thought to restrict their life-cycles and limit population growth. In 2019 and 2020, we collected wild berries from two counties in the Upper Peninsula of Michigan, with long, cold winters, to determine the prevalence, host range, and seasonal/temporal variation of SWD. We found …

Changes In Foliar Chemistry And Nutrient Resorption In Northern Hardwood Forests In Response To Long-Term Experimental Nitrogen And Phosphorus Addition, Jenna M. Zukswert, Timothy J. Fahey, Matthew A. Vadeboncoeur, Daniel S. Hong, Ruth D. Yanai
Faculty Publications
Northern hardwood forests have long been assumed to be primarily nitrogen limited, but may often be co-limited by multiple elements. Nutrient limitation can be inferred through responses of foliar and litter chemistry to nutrient addition over time. We compared community-level foliar and litter chemistry and resorption efficiency in a long-term, factorial nitrogen (N) and phosphorus (P) fertilization study across 10 forest stands at three sites in New Hampshire, where N and P were added annually. We measured N, P, calcium (Ca), magnesium (Mg), and potassium (K) in foliage from codominant trees and in fresh litter in 2008–2010 (pretreatment) and again …

Understanding The Accuracy And Best Use Of The Woodland Stick As A Tree Height And Diameter Measurement Tool: A Case Study In Oregon, Francisca Belart, Lauren Grand, Alicia Christiansen
Journal of Extension
We conducted a study to assess the accuracy of the Woodland Stick in determining tree diameter and height as compared to professional measurements and how bias can affect tree volume calculation. After comparing professional measurements with five non-professionals (NP’s) using the Woodland Stick, we found that three out of five NP’s had significant differences in mean dbh, and all of the NP’s had significant differences in mean total height. The overall bias for dbh across users was +0.5 inches and +5.1 ft for height. These deviations can result in volume differences between 0 and 30 bf on a single tree.

The olive (Olea europaea L.) is widely distributed due to its high adaptability to different environmental conditions. However,in recent years, sudden extreme temperature decreases and frost damage have caused significant yield and quality losses in some regions.This situation has led to the development of varieties with high frost tolerance, suitable for regions where cold damage may occur.It takes many years to develop varieties using classical breeding methods in olives. Therefore, early selection should be made usingbiotechnological methods. Markers about any trait provide a great advantage, especially in plant species with a very long juvenile sterilityperiod, as they allow for a …

Excessive salinity poses serious threats to crop productivity and global food security. Salt stress reduces crop growth and final productivity by inducing ionic, osmotic, and oxidative damage. Applying plant growth hormones is thought to be an efficient method of reducing the negative effects of salinity. Brassinosteroids (BRs) are plant hormones that have demonstrated appreciable effects against different abiotic stresses. BRs can mitigate the deleterious impacts of salt stress by improving water and nutrient uptake, membrane stability, antioxidant activities, and osmolyte synthesis while maintaining the hormonal balance. Furthermore, BRs can also improve the metabolic and molecular responses of plants to help …
