Signals, cues, and information use in foraging decisions of herbivorous insects and a leaf-folding plant
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 12/1/2024] Group living organisms rely heavily on cues and signals from other group members to make decisions. I studied how foraging decisions are influenced by communication in two species of plant-feeding ...
Adaptations enabling PBP1a-driven polar growth in Agrobacterium tumefaciens
(University of Missouri--Columbia, 2023)
a unique set of challenges. In one, A. tumefaciens freely lives in the soil where it encounters many environmental stressors such as salinity, antibiotics, nutrient availability, changes in pH, and temperature that hinder its ability to grow. Upon...
(Socio-)ecological tools and insights for a changing climate
(University of Missouri--Columbia, 2022)
as ecosystem resilience. In my dissertation, I call into question conventional lethal sampling approaches for bumble bees, an economically and ecologically important pollinator group, and simultaneously advance non-lethal techniques. Additionally, with aims...
Mining the Drosophila gustatory receptor family for new thermosensitive proteins : basic science and tool development
(University of Missouri--Columbia, 2021)
Extrinsic control of neural activity is a powerful paradigm for understanding how neural circuits operate and regulate behavior. Traditionally, optogenetic tools are used to activate or inhibit neuronal activity with light. ...
Unveiling glial pathways involved in neuronal communication
(University of Missouri--Columbia, 2022)
is an excellent model for gaining genetic insight onto basic glio-biology. The overall goal of this dissertation was to identify glial genes which modify neuronal activity. To accomplish this, I took advantage of the TRPA1-induced paralysis behavior...
Disentangling the feedback signals coordinating the ion channel mRNA profile of motor neurons of the crustacean stomatogastric ganglion
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] How do neural networks reliably produce motor behaviors over the course of an organism's life? Remarkably, neural networks are able to stabilize their outputs in spite of physiological perturbations ...
