Resource selection, predation risk, and population dynamics of woodland caribou
… caribou declines indirectly through changes to apparent competition dynamics within the predator-prey community. Apparent competition occurs as a negative indirect interaction between prey species, mediated by their direct interactions with a shared predator. I first review apparent competition, …

Habitat Selection and Range Overlap of Moose and White-tailed Deer in the Boreal Plains of Saskatchewan
… 50 years. This expansion raises concerns about apparent competition, where one species increases predation or pathogen pressure on another. Such interactions are well documented between white-tailed deer and caribou; here, I examine potential apparent competition between white-tailed deer and …

Biogeographical Approaches for Studying Species Invasion
… herbivory suggest a possibility of an asymmetric apparent competition between native and invasive genotypes. A replicated field study in four sites along the Atlantic Coast showed that invasive genotypes could suppress the fitness of native genotypes by herbivore-mediated apparent competition. …

Interactions between Bromus tectorum, grasshoppers, and native plants in sagebrush steppe communities
… by native herbivores through the mechanism of apparent competition: species competing indirectly through shared natural enemies. If an invasive exotic is a less preferred food source for herbivores than native plants, per capita feeding impacts may increase on natives, thus facilitating exotic …

Ionic balance and growth of carnations
… the uptake of the other cations. There was no apparent competition among anions for uptake. Sulfate and nitrate remained fairly constant in the plant tissue regardless of nutrient treatment. Phosphate was readily taken up, probably in luxury quantities. The chloride ion apparently was taken up …

Mechanistic studies of a multidrug efflux protein from <i>Escherichia coli</i>
… for binding to MdtM at pH values < 6.7. This apparent competition may be as a result of direct competition for the binding site but is more likely as a result of proton mediated conformational changes. These changes could lead to MdtM no longer being in the high affinity inward open …

Assessing the effects of invasive Ligustrum sinense and Lonicera japonica on rare and federally threatened Scutellaria montana
… was included to help isolate the effects of competition from non-insect herbivory, another possible pressure negatively influencing S. montana, and to isolate the effects of competition from apparent competition. I hypothesized that interspecific competition with L. sinense and L. japonica …

Resource selection and abundance estimation of moose: Implications for caribou recovery in a human altered landscape
… prey for wolves (Canis lupus), resulting in apparent competition. We first examined habitat selection of moose in 2 regions with differing intensities of human disturbance in west-central Alberta and east-central British Columbia to assess how human disturbance affects the spatial separation …

EFFECT OF NICOTINE ON LUNG S-ADENOSYLMETHIONINE AND PNEUMOCYSTIS PNEUMONIA DEVELOPMENT
… has the potential to induce polyamine flux, an apparent competition for the same polyamine transport system impairs simultaneous uptake of both compounds at effective concentrations. In conclusion, we showed that chronic nicotine administration causes reduction of AdoMet levels in rat lung …
