Colonization dynamics of oro-gastrointestinal microbes critical to infant health
… vivo. In Chapter 5, a model for Candida albicans colonization in neonatal piglets was developed. C. albicans is a commensal fungus for which colonization mechanisms are understudied. A surveillance analysis identified a C. albicans–negative piglet population at the University of Illinois-Urbana …

Changes in colonization dynamics and community structure of protozoans and macroinvertebrates in response to stress
The response of macroinvertebrate and protozoan colonization dynamics to industrial pollution was determined in a thermal organic effluent and in a metals effluent. The relationship of the time course data to the MacArthur-Wilson model is considered, along with Pinkham and Pearson's community …

Nasopharyngeal colonization dynamics with Streptococcus pneumoniae and associated antimicrobial resistance in a South African birth cohort
Introduction: Nasopharyngeal (NP) colonization by Streptococcus pneumoniae (the pneumococcus) precedes the development of respiratory tract infection. Colonization by antimicrobial-resistant pneumococci, especially in infants, is a major public health concern as pneumococcus is a frequent cause of …

Patterns of microbial community development in isolated aquatic systems
… were used as aquatic islands to investigate the colonization dynamics of protozoan, algal and microinvertebrate taxa. Polyurethane foam (PF) artificial substrates were used as sampling devices in these systems. Distance from another aquatic system was found to have a significant effect …

Reproductive traits of pioneer gastropod species colonizing deep-sea hydrothermal vents after an eruption
The colonization dynamics and life histories of pioneer species are vital components in understanding the early succession of nascent hydrothermal vents. The reproductive ecology of pioneer species at deep-sea hydrothermal vents may provide insight into their dispersal, population connectivity, and …

The role of rooting strategies on the eco-hydrology of semi-arid regions
… ability of the new scheme to capture the complex dynamics of natural systems was evaluated by comparisons to hourly-timescale energy flux, soil moisture and vegetation growth observations from the Walnut Gulch Experimental Watershed, Arizona. Very good agreement was found between the model and …

Reproductive traits of pioneer gastropod species colonizing deep-see hydrothermal vents after an eruption
The colonization dynamics and life histories of pioneer species are vital components in understanding the early succession of nascent hydrothermal vents. The reproductive ecology of pioneer species at deep-sea hydrothermal vents may provide insight into their dispersal, population connectivity, and …

Structure and function of zooplankton colonization in twelve new experimental ponds
… (Coleman 1981). Physico-chemistry, zooplankton colonization dynamics, zooplankton community structure and function were analyzed every two weeks from 5 February 1988 to 10 February 1989. Ponds varied in physico-chemistry at points in time but followed similar patterns during the study year. …

Analysis of Bacterial-Host Interactions Between Campylobacter jejuni and the Avian Host During Commensalism
… C. jejuni promotes an asymptomatic, intestinal colonization of many animals, especially avian species, to result in commensalism. The primary route of transmission to humans is through the consumption or handling of undercooked poultry meats, making C. jejuni of particular importance to the …

Ecology of plant-animal interactions during plant population expansion processes
… in different contexts, affecting natural dynamics. Currently, significant changes in the landscape, such as rural abandonment or the protection of natural areas, are creating a new ecological context for the formation and regeneration of new forested areas. Although the of the role of …

Bacterial colonization of the nasopharynx in paediatric patients with acute respiratory viral symptoms
… those vaccine strains. This will likely alter colonization dynamics, with perhaps serotype replacement or the emergence of vaccine escape mutants. Evidence to date suggests that vaccine serotypes have been partially displaced, and that some non-vaccine strains, such as 19A, are increasingly …

Effects of diversity on community assembly dynamics in newly formed pond communities
… a new habitat will influence community assembly dynamics. Previous studies have shown that species diverse communities can buffer against invasion by heterospecifics. In addition, the monopolization hypothesis predicts that a genetically diverse population will be more likely to adapt to the …
