The consumption of alcohol prior to food intake results in alcohol metabolism occurring in the liver, and the liver is often damaged in chronic alcoholics. This paper highlights the possibility that alcohol consumption in the absence of adequate nutrition after an extended period of time may lead to activation of the glyoxylate cycle, an energy pathway associated with the conversion of fat into carbohydrate which until recently was thought to only exist in plants and bacteria.

AbstractNutrient enrichment can simultaneously increase and destabilise plant biomass production, with co‐limitation by multiple nutrients potentially intensifying these effects. Here, we test how factorial additions of nitrogen (N), phosphorus (P) and potassium with essential nutrients (K+) affect the stability (mean/standard deviation) of aboveground biomass in 34 grasslands over 7 years. Destabilisation with fertilisation was prevalent but was driven by single nutrients, not synergistic nutrient interactions. On average, N‐based treatments increased mean biomass production by 21–51% but increased its standard deviation by 40–68% and so consistently reduced stability. Adding P increased interannual variability and reduced stability without altering mean biomass, while K+ had no general effects. Declines in stability were largest in the most nutrient‐limited grasslands, or where nutrients reduced species richness or intensified species synchrony. We show that nutrients can differentially impact the stability of biomass production, with N and P in particular disproportionately increasing its interannual variability.

The rapid growth of agriculture has led to a significant increase in energy utilization and CO2 emissions. Agriculture performs a pivotal role in improving every country’s economy. The current study has the main objective to analyses the long-run impact of agricultural CO2 discharge on economic growth, energy consumption (electricity utilization in the agriculture sector), financial development, foreign direct investment (FDI), and population for India. For the period 1978–2018, we applied ADF, PP, ERS, and KPSS unit root and Z&A and CMR structural interval tests to evaluate the stability and breaks in the data set. We check the cointegration of study variables through ARDL, Engle–Granger, and Johansen’s cointegration approaches. The findings of the long-run analysis showed a cointegration among the variables, which reveals that an escalation in economic growth and financial development refine the natural environment, while the upsurge in FDI and population further deteriorate the climate in India. However, agricultural sector electricity use shows an insignificant association with CO2 emissions for both periods. On the basis of results, we recommend that legislators should offer an environment that provides opportunities for financial development and economic growth.

AbstractChanges in land‐use and climate affect the distribution and diversity of plant and animal species at different spatiotemporal scales. The extent to which species‐specific phenotypic plasticity and biotic interactions mediate organismal adaptation to changing environments, however, remains poorly understood. Woody plant expansion is threatening the extent of alpine grasslands worldwide, and evaluating and predicting its effects on herbivores is of crucial importance. Here, we explore the impact of shrubification on the feeding efficiency of Pyrenean chamois (Rupicapra p. pyrenaica), as well as on the three most abundant coexisting domestic ungulate species: cattle, sheep and horses. We use observational diet composition from May to October and model different scenarios of vegetation availability where shrubland and woodland proliferate at the expense of grassland. We then predicted if the four ungulate species could efficiently utilize their food landscapes with their current dietary specificities measuring their niche breath in each scenario. We observed that the wild counterpart, due to a higher trophic plasticity, is less disturbed by shrubification compared to livestock, which rely primarily on herbaceous plants and will be affected 3.6 times more. Our results suggest that mixed feeders, such as chamois, could benefit from fallow landscapes, and that mountain farmers are at a growing economic risk worldwide due to changing land‐use practices and climate conditions.
