Department of Agronomy and Horticulture: Faculty Publications

DREB has been reported to be involved in plant growth and response to environmental factors. However, the function of DREB in growth and development has not been elucidated in alfalfa (Medicago sativa L.), a perennial tetraploid forage cultivated worldwide. In this study, an ortholog of MtDREB1C was characterized from alfalfa and named MsDREB1C accordingly. MsDREB1C was significantly induced by abiotic stress. The transcription factor MsDREB1C resided in the nucleus and had self-transactivation activity. The MsDREB1C overexpression (OE) alfalfa displayed growth retardation under both long-day and short-day conditions, which was supported by decreased MsGA20ox and upregulated MsGA2ox in the OE …

Sustainability And Drivers Of Populus Tremuloides Regeneration And Recruitment Near The Southwestern Edge Of Its Range, Connor D. Crouch, Nicholas P. Wilhelmi, Paul C. Rogers, Margaret M. Moore, Kristen M. Waring

Aspen Bibliography

Quaking aspen (Populus tremuloides Michx.) ecosystems are highly valued in the southwestern United States because of the ecological, economic, and aesthetic benefits they provide. Aspen has experienced extensive mortality in recent decades, and there is evidence that many areas in Arizona, United States lack adequate recruitment to replace dying overstory trees. Maintaining sustainable levels of regeneration and recruitment (i.e. juveniles) is critical for promoting aspen ecosystem resilience and adaptive capacity, but questions remain about which factors currently limit juvenile aspen and which strategies are appropriate for managing aspen in an increasingly uncertain future. To fill these critical knowledge gaps, …

The Effects Of Age And Type Of Rearing On Contrafreeloading Behavior In Female Goats, Carly Weems

Honors Theses

Contrafreeloading (CFL) is the willingness of an animal to work for food. This study continues the 2022 pilot study, in which thirteen female goats from the Andrews University Sustainable Agriculture Department were tested to see if there was any correlation between age and contrafreeload in goats, and additionally investigates whether or not there is any correlation between type of rearing and contrafreeloading behavior in female goats. The pilot study found no direct correlation between age and contrafreeloading, therefore early life feeding techniques were also considered for this study.

Eighteen female goats representing three different age groups and three types of …

Where Have All The Flowers Gone? A Call For Federal Leadership In Deer Management In The United States, Bernd Blossey, Darragh Hare, Donald M. Waller

Aspen Bibliography

Forests in the United States continue to lose biodiversity and many fail to regenerate due to high deer (family Cervidae) abundance. Declines in biodiversity and overall ecosystem health due to high deer populations increases prevalence of wildlife and human diseases associated with increasing tick abundances and decreases forest resilience and the ability to deliver benefits provided by healthy ecosystems. In the eastern and midwestern United States, white-tailed deer (Odocoileus virginianus) are the main stressor, while in the western U.S. elk (Cervus elaphus) and black-tailed and mule deer (Odocoileus hemionus) can become equally problematic.

What Soil Is Worth: A Cost-Benefit Framework Analysis Of Syntropic Farming, Aubrey Kettley

Independent Study Project (ISP) Collection

Syntropic farming, a type of regenerative agriculture, models its farming system after a forest. This type of farming prioritizes soil health while also providing a varied yield of crops. Because it is a fairly new system globally, little research has been done on the economic impacts of syntropic farming, and therefore the feasibility of scaling up regenerative systems like this. This study aims to analyze the economic feasibility of this system through a literature review and a cost-benefit analysis framework. The results highlight the applicability, environmental advantage and economic feasibility of the system. Based on the presented framework, the short …

Sovereign Seeds: Analyzing The Sustainability Of Peasant Seeds In The Context Of Climate Change And Rural Exodus In Tunisia, Alice Carlson

Independent Study Project (ISP) Collection

How sustainable are peasant seeds? I answer this question on the basis of three elements: environment, economy, and social justice. Using interviews with farmers from various regions of Tunisia, an interview with an expert on climate change and migration, and an interview with a civil society organization working to promote sustainable agriculture, I found that peasant seeds are a sustainable solution for a suffering agricultural sector. Depleted water sources and drought are bringing to light the problems with water-intensive hybrid seeds, and farmers are losing money. As young men increasingly leave the agricultural sector, women are left behind, finding themselves …
