Meat from silvopastoral systems, due to its provision of numerous ecosystem services such as wildfire risk reduction in Mediterranean forests, can address societal growing demands for meat produced with lower environmental impacts. Differentiation of meat from these systems may contribute to their economic sustainability and hence to reverse their decline in the Mediterranean. This study investigated consumer preferences and willingness-to-pay (WTP) for beef and lamb meat from silvopastoral systems associated to the provision of wildfire prevention service and explored two alternative ways of labelling this service. Through a choice experiment survey considering type of pasture, length of grazing period, production distance and price, we gathered data from 1209 meat consumers in two Spanish cities. We considered forest grazing with a target purpose as a level in the type of pasture attribute and it was presented either as grazing to prevent wildfires or grazing to reduce biomass in two alternative versions of the valuation survey. The random parameter logit model revealed the highest preferences and WTP towards nearby production distances, followed by targeted grazing and forest grazing, while the length of grazing period was less relevant. No significant differences in consumers WTP were found between conveying targeted grazing either as fire prevention or biomass reduction. Our findings also suggest that consumers' preferences varied with location, attitudes towards local food and environmental role of grazing and consumption habits. Knowledge gathered in our work contributes to understand consumers perceptions on the beneficial environmental impacts of meat production.

Livestock grazing endophyte-infected (E+) tall fescue can exhibit persistent systemic vasoconstriction and fescue toxicosis. Isoflavones in legumes, most notably red clover (RC), are known hypotensive agents. The objective of the experiment was to evaluate the effect of isoflavone supplementation via RC hay, every day or every other day (QOD), on average daily gain (ADG) of steers grazing E+ tall fescue pastures and their physiological recovery after grazing when managed on a non-toxic diet (28-d).

Accurate estimation of individual feed intake is essential for calculating feed efficiency, planning diets, monitoring cow herds, and managing grazing cows. This study aimed to evaluate the performance and applicability of estimation equations developed to predict pasture herbage DMI (PHDMI) in dairy cows using behavioral traits recorded and scored by the RumiWatch system. The study had 4 primary objectives: (1) to compare the behavioral characteristic outputs of 2 versions of the RumiWatch converter (0.

Many ant species show dramatic shifts in behaviour when infected with parasites, but the molecular basis of these behavioural changes is not well understood. An example is the wood ant, Formica aserva, which serves as an intermediate host for the lancet liver fluke, Dicrocoelium dendriticum. Infected ants leave their nests during the cool hours of the day, ascend a flower and then attach themselves to a petal with their mandibles.

Microscale symbioses can be critical to ecosystem functions, but the mechanisms of these interactions in nature are often cryptic. Here, we use a combination of stable isotope imaging and tracing to reveal carbon (C) and nitrogen (N) exchanges among three symbiotic primary producers that fuel a salmon-bearing river food web. Bulk isotope analysis, nanoSIMS (secondary ion mass spectrometry) isotope imaging, and density centrifugation for quantitative stable isotope probing enabled quantification of organism-specific C- and N-fixation rates from the subcellular scale to the ecosystem.

We have developed a vacuum-compatible liquid flat-jet apparatus that delivers stable, sub-micrometer sheets for soft-x-ray spectroscopy. Interchangeable PEEKsil microjets (ϕ 25-100 μm) collide to form a leaf-like jet that runs reproducibly for more than 6 h at ∼0.1 Pa.
