Unlocking Probiotic Potential: Physicochemical Approaches to Evaluate Probiotic Bacterial Adhesion Potential to the Intestinal Tract

open access: yesMolecular Nutrition &Food Research, EarlyView.
From the oral cavity to the establishment of bacterial adhesion in the intestinal tract, probiotic cells traverse 4 main stages: (1) bacterial transport, (2) reversible adhesion, (3) irreversible adhesion, and (4) biofilm formation. Each stage involves distinct mechanisms that govern the adhesion potential of bacteria to the intestinal mucus, which ...

General mechanisms for a top–down origin of the predator–prey power law

open access: yesOikos, EarlyView.
The ratio of predator‐to‐prey biomass density is not constant along ecological gradients: denser ecosystems tend to have fewer predators per prey, following a scaling relation known as the ‘predator–prey power law'. The origin of this surprisingly general pattern, particularly its connection with environmental factors and predator–prey dynamics, is ...

Paving the Way for Improved Representation of Coupled Physical and Biogeochemical Processes in Arctic River Plumes—A Case Study of the Mackenzie Shelf

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Processes affecting the transformation of riverine dissolved organic carbon (DOC) across the land‐to‐ocean aquatic continuum are still poorly constrained in Arctic models, leading to large uncertainties in simulated air–sea CO2 fluxes of the coastal periphery.

Longitudinal Variability in the Oxygen Demand of Channel Bed Matrix Sediment in a UK Agricultural Catchment: Implications for Managing the Sediment Problem

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The presence of excess fine‐grained matrix sediment in channel beds can exert an oxygen demand in this critical habitat for fish spawning and invertebrates. Therefore, reducing the oxygen demand of channel bed sediment through targeted intervention may deliver better cost–benefit from catchment management.
