Variation In Response To Phosphorus Among Sweetpotato (Ipomoea Batatas L.) Cultivars, Jeffrey Cole Denis Gregorie
Variation In Response To Phosphorus Among Sweetpotato (Ipomoea Batatas L.) Cultivars, Jeffrey Cole Denis Gregorie
LSU Doctoral Dissertations
Phosphorus (P) is essential for plant growth and is often a major limiting nutrient in agriculture. In sweetpotato (Ipomoea batatas), studies on the role of P on storage root yield have been limited because of the lack of response and inconsistent results across cultivars and years. Growing evidence shows that current phosphate (Pi) fertilizer rates can be reduced while maintaining productivity. Newly published molecular evidence shows differential expression of phosphate starvation response genes among sweetpotato cultivars, further supporting the hypothesis of cultivar-specific Pi sensitivity. The research herein sought to characterize root system architecture and yield response to Pi …
Trait Variation In Bryophytes At Karst Cave Entrances, Chenoa Briggs
Trait Variation In Bryophytes At Karst Cave Entrances, Chenoa Briggs
2023 Midwest Ecology & Evolution Conference
Cave entrances are critical ecosystems in their role as ecotones between the interior cave environment and the surrounding external environment. Bryophytes are highly sensitive to environmental changes and many species found at caves are specialists to those habitats. This study aims to identify how functional traits of bryophytes are affected by the cave environment. Bryophytes and environmental variables were sampled from six cave entrances. Functional trait data was collected from literature. The data from this study supplies information on the functional traits of bryophytes and can provide insight into the effects of environmental pressures on community assembly.
Bryophyte Ecosystem Services: How Bryophytes Impact Ecosystem Processes And Their Use In Urban Systems, Keila Spangler
Bryophyte Ecosystem Services: How Bryophytes Impact Ecosystem Processes And Their Use In Urban Systems, Keila Spangler
University Honors Theses
Bryophytes, which include mosses, liverworts, and hornworts, are non-vascular plants that provide crucial ecosystem services in natural and urban systems. In natural systems, these services include carbon, water, and nutrient cycling and maintenance of community level biodiversity. In urban systems, bryophytes can be used as green roof substrate, as bioindicators to monitor pollution and air quality, for horticulture uses, and in medicine. Although bryophytes possess some qualities, such as reproduction by spores, that may give them an advantage compared to vascular plants as the climate warms, their response to climate change remains understudied. This paper will review the literature on …
Spatio-Temporal Dynamics Of Fungal Communities And Their Effects On Plants, Kel Cook
Spatio-Temporal Dynamics Of Fungal Communities And Their Effects On Plants, Kel Cook
Biology ETDs
Fungi perform several critical functions in the environment. Spatiotemporal distributions of fungal communities will mediate when and where these functions happen and how they vary across the landscape. I first explored tropical tree canopy fungal community variation at small spatial scales and documented near total turnover of fungi across sub-meter distances and among adjacent substrates. The second chapter analyzed fungal turnover over the course of three years, where community stability was driven primarily by abundant fungi. In the third chapter, I tested effects of the environment, including host plant and habitat, on canopy fungal communities and found only small effects, …
Intraspecific Variation In Dehydration Tolerance: Insights From The Tropical Plant Marchantia Inflexa, Rose A. Marks
Intraspecific Variation In Dehydration Tolerance: Insights From The Tropical Plant Marchantia Inflexa, Rose A. Marks
Theses and Dissertations--Biology
Plants are threatened by global change, increasing variability in weather patterns, and associated abiotic stress. Consequently, there is an urgent need to enhance our ability to predict plant community dynamics, shifts in species distributions, and physiological responses to environmental challenges. By building a fundamental understanding of plant stress tolerance, it may be possibly to protect the ecological services, economic industries, and communities that depend on plants. Dehydration tolerance (DhT) is an important mechanism of water stress tolerance with promising translational applications. Here, I take advantage natural variation in DhT to gain a deeper insight into this complex trait. In addition, …
