(University of Oregon, 2022-10-26)Animals are colonized by a consortium of microbes that sense and respond to their immediate environments. These microbes, collectively called the gut microbiota, promote epithelial proliferation in a diversity of animal ...
-
(University of Oregon, 2020-02-27)Two central questions in neuroscience are how the brain is capable of both generating the diversity of neurons necessary for generating appropriate behaviors and how developmental programs are capable of then wiring these ...

A Microsporidian Parasite Infects Ribbon Worms of the Genus Maculaura on the Eastern Pacific Coast (University of Oregon, 2019-04-30)The small nemertean <i>Maculaura alaskensis</i> is used as a model for studies of pilidiophoran development. During several microinjection experiments, it became clear several batches of oocytes obtained from wild-caught ...

(University of Oregon, 2018-09-06)Invasive colonial tunicates pose substantial economic threat to the shellfish aquaculture industry, but their population dynamics and ecological impacts are highly variable and region-specific. This thesis contributes to ...
-
(University of Oregon, 2021-09-13)Pattern formation, or specifically symmetry breaking, is a fundamental process essential for proper asymmetric cell division. In asymmetrically dividing stem cells, the evolutionarily conserved Par polarity complex localizes ...
-
(University of Oregon, 2024-03-25)Host-microbe interactions within the gastrointestinal tract have long been recognized as pivotal for maintaining physiological balance. However, the intricate mechanisms underlying these interactions remain enigmatic. This ...
-
(University of Oregon, 2018-10-31)One feature of the brain is that different parts of it respond to different stimuli. This means not all brain regions or neurons within those regions are active at a given moment. This feature of the brain gives it the ...

(Thesis (Ph.D.)--Oregon, Dept. of Biology, 1968)
-
(Thesis (M.S.)--University of Oregon, 1993., 1993)The lower distributional limits (fronts) of callianassid shrimp populations were observed at five sites in South Slough, Coos Bay estuary, Oregon. Fronts at four sites exhibited similar shoreward-seaward movements ...

(Thesis (Ph.D.)--University of Oregon, 1973, 1973-06)
-
(University of Oregon theses, Dept. of Biology, Ph.D., 1978, 1978-06)
-
(University of Oregon, )The communities of microorganisms associated with humans and other animals are characterized by a large degree of diversity and unexplained variation across individual hosts. While efforts to explain this variation in ...

(University of Oregon theses, Dept. of Biology, M.S., 1980, 1980-12)
-
(University of Oregon, 2008-09)Cellular polarity is a biological mechanism that is conserved across metazoa and is used in many different biological processes, one of which is stem cell self-renewal and differentiation. Stem cells generate cellular ...
-
(University of Oregon, 2006-12)Survival depends on our ability to detect and integrate sensory information from multiple modalities, allowing for the most efficient behavioral response. For example, barn owls must combine sights and sounds from the ...
-
(University of Oregon, 2021-04-29)Quorum sensing is a mode of bacterial communication that relies on the production and secretion of signaling molecules known as autoinducers. Group-wide detection of autoinducers gives rise to collective gene expression ...
-
(University of Oregon, 2013-10-03)Human intestinal microbiomes exhibit a large degree of interindividual compositional variation. Animal models, such as the zebrafish, facilitate the design of controlled and highly replicated studies that allow us to ...
-
(University of Oregon, 2018-04-10)Diabetes is a metabolic disease characterized by the loss of functional pancreatic beta cells. The incidence of diabetes has risen rapidly in recent decades, which has been attributed at least partially to alterations in ...
-
(University of Oregon, 2011-12)This dissertation describes research into microbial influences on host signaling in the zebrafish intestine. Vertebrate organisms are consistently exposed to microbes, especially on epithelial tissues that are exposed to ...
