A human fashion brand model to define critical symbiotic relationships for celebrity fashion emulation
… into adulthood, in much the same way that relationships with peers do. Preceding celebrity research has involved using the “celebrity as an endorser for another brand's product… rather than understanding the celebrity brand itself” (Moulard, Garrity, & Rice, 2015). This investigation …

Impacts of symbiotic relationships on risk, return and value of micro-, small and medium enterprises
This thesis investigates the impact of symbiotic relationships on risk, return and value of micro-, small and medium enterprises (MSMEs). The research study examines how connections and networking help MSMEs to enhance financial gains by maximising return and minimising risks associated with …

Symbiotic relationships of <i>alnus glutinosa</i> with arbuscular mycorrhizal fungi and with <i>frankia</i>
The occurrence in Scotland of arbuscular mycorrhizal fungi (AMF) infective on <i>Alnus glutinosa</i> and the effects on early growth of inoculation of seedlings with AMF and <i>Frankia </i>were investigated. AMF characteristic of <i>Glomus</i>-like fungi were detected microscopically in <i>A. …

Invasive Hosts and their Context Dependent Relationships with Native Symbionts
Symbiotic relationships display plasticity through time, depending on a variety of factors that include host properties, symbiont densities, and environmental conditions. Invasive species can affect symbiotic relationships by introducing invasive symbionts, reducing the population of native …

Symbiosis
… M. Foucault, 1979 All elements exist in relationships of varying degrees. These engagements are considered symbiotic when there is an intimate understanding and exchange of each other's values which govern their associations. Those biological interrelationships which evolve reciprocally …

Hitching a ride: A gastropod-associated microbiome community at a Hydrate Ride methane seep and impacts on local biogeochemical cycling
… the first discovery of cold seeps in the 1980s. Symbiotic relationships, often rooted in geochemistry of the environment, have proven to be ubiquitous at cold seeps. However, our understanding of symbiotic relationships at extreme environments is limited. In this thesis, we first review two kinds …

Ecology and behaviour of burrowing prawns and their burrow symbionts
… other species, often leading to the evolution of symbiotic relationships. Engineered structures provide non-trophic (e.g. refuge) and trophic functions (e.g. food) for burrow symbionts, however, the relative importance of these functions for symbionts is poorly understood. The behavioural …

Characterization of the Genes Involved in Biosynthesis and Transport of Schizokinen, a Siderophore Produced by <em>Rhizobium leguminosarum</em> IARI 917.
… are soil dwelling organisms that form symbiotic relationships with host plants and fix atmospheric nitrogen, while the bacteria receive nutrients. <em>R. leguminosarum</em> IARI 917 produces a siderophore characterized as 'schizokinen'. In the present study, we have characterized the …

Isolation and Identification of the Siderophore "Vicibactin" Produced by <em>Rhizobium leguminosarum</em> ATCC 14479.
… are characterized both by their formation of symbiotic relationships with leguminous plants and their ability to fix atmospheric nitrogen. <em>Rhizobium leguminosarum</em> ATCC 14479, which infects the red clover <em>Trifolium pratense</em>, was found to produce a trihydroxamate siderophore. …

Isolation, Purification, and Chemical Characterization of the Dihydroxamate-Type Siderophore, "Schizokinen," Produced by <em>Rhizobium leguminosarum</em> IARI 917.
… are characterized by their ability to form symbiotic relationships with leguminous plants, where they can fix nitrogen for the host plant and the plant provides the bacteria with nutrients. Under iron-limiting conditions, Rhizobia are known to produce siderophores. <em>Rhizobium …

The bi-directional relationship between gut microbiota and autoimmunity
… of microbiota. These microbes have evolved symbiotic relationships with humans due to their close proximity with their host. As a result, the immune system adapts to the microbiota thus modulating immunological function. Autoimmunity is a state in which there are aberrant immune responses …

A hybrid mathematical model of fungal mycelia: tropisms, polarised growth and application to colony competition
… and supporting plants and animal life through symbiotic relationships. Certain species of fungi are common pathogens causing disease and infection in plants and animals. The highly integrated nature of fungi in relation to the environment and all life emphasises the importance of developing a …

Invertebrate Fauna of the Carapaces of the Texas River Cooter (Pseudemys texana) and the Red-Eared Slider (Trachemys scripta elegans)
Symbiotic relationships occur between many pairs of species of organisms. The relationship between algae and turtles recently has been quantified. The relationship between turtles and aquatic invertebrates is less known. This study described quantitatively the invertebrate fauna inhabiting the …
