Helicobacter pylori Outer Membrane Vesicles Engage TLR2 Through NapA to Promote Epithelial Association and Inflammatory Signalling

Journal of Extracellular Vesicles, Volume 15, Issue 10, October 2026.
ABSTRACT Helicobacter pylori infection is characterized by chronic gastric inflammation driven by persistent activation of innate immune signalling pathways. Outer membrane vesicles (OMVs) released by H. pylori are important mediators of host–pathogen interactions. Although several mechanisms of OMV internalization have been described, how specific OMV‐

The Beneficial Effects of Sustainable Farming on Multitrophic Biodiversity Are Amplified Under Harsh and Less Predictable Environmental Conditions

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT The expansion and intensification of agricultural lands are major contributors to the global biodiversity loss. Alternative sustainable management practices, such as integrated and organic farming, have emerged as tools to mitigate this loss and make food production and nature conservation compatible.

High and dry: Environmental conditions drive opportunities for disease transmission in desert bighorn sheep

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
By using probabilistic models to predict contacts as a function of spatially and temporally varying environmental conditions, we show that population‐level conditions at the time of disease introduction can structure opportunities for transmission within each population.

Effects of Forest Cover and Seasonality on Several Faunal Groups in Cattle Ranching Landscapes of Los Tuxtlas, Mexico

Biotropica, Volume 58, Issue 4, July 2026.
Forest cover within cattle ranches can strongly shape faunal biodiversity. In Los Tuxtlas, Veracruz, Mexico. We show that butterflies, moths, dung beetles, and birds respond differently to forest cover across habitats (pastures vs. forest fragments) and seasons, as a function of their specialization and resource needs.
