Spatial context allows the evolution of the control of nitrification by plants

open access: yesJournal of Ecology, EarlyView.
Using a theoretical approach, we show that assuming that the effects of the control of nitrification are spatially restricted to the rhizosphere, the control of nitrification is likely to be selected in perennial plants and ecosystems in which nitrate losses are greater than ammonium losses. The selected strategy optimizes biomass production.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

open access: yesIntegrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Wet Lab Protocols Matter: Choice of DNA Extraction and Library Preparation Protocols Bias Ancient Oral Microbiome Recovery

open access: yesMolecular Ecology Resources, EarlyView.
ABSTRACT Ancient DNA (aDNA) analysis of archaeological dental calculus has provided a wealth of insights into ancient health, demography and lifestyles. However, the workflow for ancient metagenomics is still evolving, raising concerns about reproducibility.

Effectiveness of the iVac System Compared to Conventional Irrigation and Ultrasonic Activation in Reducing Microbial Biofilm, Lipopolysaccharides and Apical Extrusion

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This in vitro study evaluated the effectiveness of irrigation techniques (IT)—conventional irrigation (CI), ultrasonic activation (UA), and iVac system (IA)‐ using 2.5% NaOCl and saline in reducing Enterococcus faecalis, Escherichia coli and Candida albicans in root canals and intratubular dentine.
