Medicago Sativa L. Saponin‐Driven Lactobacillus Intestinalis Restores Intestinal Stemness in Naturally Aged Mice via the Bile Acid‐FXR‐Wnt Signaling Axis

Advanced Science, EarlyView.
This study examines the mechanism by which alfalfa saponin (AS) regulates intestinal stemness via modulation of the gut microbiota. The results indicate that AS significantly increases the abundance of Lactobacillus intestinalis, which subsequently activates Wnt signaling via bile acid metabolism and enhances intestinal stemness. These findings provide

Seedling emergence and herbage yield of summer‐active tall fescue sown at different times and sowing depths

Grassland Research
Background Tall fescue is sensitive to sowing depth and, in the Pampas region of Argentina, its sowing is often delayed from autumn (average air temperature 18.5°C) to winter (average air temperature 10.0°C).

Biomimetic Multiscale‐Structured Biomass Graphene/Polyurethane Sponge Composite for Flexible Pressure Sensors and Intelligent Cushioning Materials

Advanced Science, EarlyView.
In this study, a multifunctional conductive sponge composite (MAPU) is developed using a biomimetic, hierarchical construction strategy emulating the growth process of natural wood. This approach involved integrating biomass‐derived graphitic nanoflakes, synthesized from luffa vine (LVGN), into a polyurethane (PU) sponge matrix.

Short‐term effects of soil texture, biochar, manure, and tillage practices on warm‐climate forage yields and nutrient content

Grassland Research
Background Biochar (BC) amendment to soils can affect crop yields negatively, especially during the first season following application, by binding essential nutrients; however, little data exist on its effects on warm‐climate forage yields and nutritive ...

Quantifying the land‐use change due to soybean‐based biodiesel in the United States

Applied Economic Perspectives and Policy, EarlyView.
Abstract We quantify the impact of soybean oil‐based biodiesel production on US cropland, using a method that accounts for the intermediate effect of soybean crushing facilities. Based on U.S. Environmental Protection Agency data for biodiesel production and proprietary data for soybean crushing facilities over 2011–2020, we find that the elasticities ...

Intake and diet preference of dairy heifers grazing mixed or alternating rows of birdsfoot trefoil and cool‐season grasses

Grassland Research
Background Mixtures with birdsfoot trefoil (BFT) increase herbage intake in grazing cattle. We hypothesized that BFT spatially separated from grasses would increase preferential grazing of BFT and herbage intake compared to grass and BFT in mixed rows ...

Urban meadows as an alternative to short mown grassland: effects of composition and height on biodiversity

Ecological Applications, 2019
There are increasing calls to provide greenspace in urban areas, yet the ecological quality, as well as quantity, of greenspace is important. Short mown grassland designed for recreational use is the dominant form of urban greenspace in temperate regions

Climate Change Agricultural Comparative Advantage and the US Trade Balance

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.

High land‐use intensity exacerbates shifts in grassland vegetation composition after severe experimental drought

Global Change Biology, 2018
Climate change projections anticipate increased frequency and intensity of drought stress, but grassland responses to severe droughts and their potential to recover are poorly understood.
