Flowering and floral visitation predict changes in community structure provided that mycorrhizas remain intact
Download2018-01-01
Pollination is critical for plant fitness and population dynamics, yet little attention is paid to the role of flowering and plant-pollinator interactions in structuring plant communities, including community responses to environmental change. Changes in arbuscular mycorrhizal fungi (AMF),...

Biotic homogenization within and across eight widely distributed grasslands following invasion by Bromus inermis
Download2019-01-01
Stotz, G. C., Gianoli, E., Cahill, J. F.
Invasive species can alter the structure and function of the communities they invade, as well as lead to biotic homogenization across their invasive range, thus affecting large-scale diversity patterns. The mechanisms by which invasive species can lead to biotic homogenization are poorly...

Dettlaff, M. A, Marshall, V., Erbilgin, N., Cahill, J. F.
Although the negative effects of root herbivores on plant fitness are expected to be similar to those of above-ground herbivores, the study of below-ground plant defences is limited compared to the rich literature on above-ground defences. Current theory predicts that concentrations of defensive...

Scaling Disturbance Instead of Richness to Better Understand Anthropogenic Impacts on Biodiversity
Download2015-01-01
Mayor, S. J., Cahill, J. F., He, F., Boutin, S.
A primary impediment to understanding how species diversity and anthropogenic disturbance are related is that both diversity and disturbance can depend on the scales at which they are sampled. While the scale dependence of diversity estimation has received substantial attention, the scale...

Grazing by wild and domesticated grazers occurs within many terrestrial ecosystems worldwide, with positive and negative impacts on biodiversity. Management of grazed lands in support of biological conservation could benefit from a compiled dataset of animal biodiversity within and adjacent to...

Large-scale insect outbreak homogenizes the spatial structure of ectomycorrhizal fungal communities
Download2019-01-01
Ectomycorrhizal fungi (plant symbionts) are diverse and exist within spatially variable communities that play fundamental roles in the functioning of terrestrial ecosystems. However, the underlying ecological mechanisms that maintain and regulate the spatial structuring of ectomycorrhizal fungal...

2015-01-01
Soil microbial communities and processes have repeatedly been shown to impact plant community assembly and population growth. Soil-driven effects may be particularly pronounced with the introduction of plants to non-native ranges, as introduced plants are not typically accompanied by transference...

Metabolism of isoniazid by neutrophil myeloperoxidase leads to isoniazid-NAD+ adduct formation: A comparison of the reactivity of isoniazid with its known human metabolites
Download2024-01-01
The formation of isonicotinyl-nicotinamide adenine dinucleotide (INH-NAD+) via the mycobacterial catalase-peroxidase enzyme, katG, has been described as the major component of the mode of action of isoniazid (INH). However, there are numerous of human peroxidases that may catalyze this reaction....

William James's \"The Will to Believe\" has been criticized for offering untenable arguments in support of belief in unvalidated hypotheses. Although James is no longer accused of suggesting we can create belief ex nihilo, critics continue to charge that James s defense of belief in what he...

Assis, Leandro C.S., Brigandt, Ingo
Taxa and homologues can in our view be construed both as kinds and as individuals. However, the conceptualization of taxa as natural kinds in the sense of homeostatic property cluster kinds has been criticized by some systematists, as it seems that even such kinds cannot evolve due to their being...
