Abstract:
... Adapting crops to warmer growing season temperatures is a major challenge in mitigating the impacts of climate change on crop production. Warming temperatures drive greater evaporative demand and can directly interfere with both reproductive and vegetative physiological processes. Most of the world’s crop species have C3 photosynthetic metabolism for which increasing temperature means higher rates ...

Abstract:
... Plant carbon isotope discrimination is complex, and could be driven by climate, evolution and/or edaphic factors. We tested the climate drivers of carbon isotope discrimination in modern and historical plant chemistry, and focus in particular on the relationship between rising [CO₂] over Industrialization and carbon isotope discrimination. We generated temporal records of plant carbon isotopes fro ...

However, the differences between photosynthetic pathways, C3 and C4, following nanomaterial exposure are poorly understood. In the current work, wheat and rice, two C3 pathway species are compared to amaranth and maize, which utilize the C4 photosynthetic mechanism. These plants were cul ...

Abstract:
... Vegetation in East Africa is generally thought to have shifted from forests to more open grasslands and savannas as global climate cooled and high-latitude ice sheets expanded during the Plio-Pleistocene. Such a shift would have greatly influenced landscape resources, and potentially hominin evolution as well. Existing records of African vegetation spanning these time-scales are generally derived ...

A comprehensive understanding of multipaddock, rotational grazing management on rangelands has been slow to develop, and the contribution of adaptive management (Briske et al. 2011) and sufficient scale (Teague and Barnes 2017) have been identified as key omissions. We designed an experiment to compare responses of vegetation and cattle in an adaptively managed, multipaddock, rotational system wit ...

Abstract:
... Chemical-looping combustion (CLC) is a combustion process with inherent separation of carbon dioxide (CO₂), which is achieved by oxidizing the fuel with a solid oxygen carrier rather than with air. As fuel and combustion air are never mixed, no gas separation is necessary and, consequently, there is no direct cost or energy penalty for the separation of gases. The most common form of design of che ...

Abstract:
... Soil labile and recalcitrant carbon (C) and nitrogen (N) are strongly controlled by plant inputs and climatic conditions. However, the interrelation of labile and recalcitrant pools with changes in plant functional groups (i.e., C3 and C4) along precipitation gradients is not fully understood. Here, we investigated the soil organic C and N (SOC and SON), labile C and N (LC and LN), recalcitrant C ...

Abstract:
... Increases in atmospheric carbon dioxide (CO₂) and global air temperature affect all terrestrial ecosystems and often lead to enhanced ecosystem productivity, which in turn dampens the rise in atmospheric CO₂ by removing CO₂ from the atmosphere. As most terrestrial ecosystems are limited in their productivity by the availability of nitrogen (N), there is concern about the persistence of this terres ...

Abstract:
... Measurements of photosynthetic assimilation rate as a function of intercellular CO₂ (A/Cᵢ curves) are widely used to estimate photosynthetic parameters for C₃ species, yet few parameters have been reported for C₄ plants, because of a lack of estimation methods. Here, we extend the framework of widely used estimation methods for C₃ plants to build estimation tools by exclusively fitting intensive A ...

Abstract:
... In silvopastoral systems, the use of land for multiple purposes diversifies economic income and improves the stability of the system. If shading levels are medium or high, cattle production is often limited by the absence of one or more forage components of the herbaceous layer (such as perennial grasses). In the present study, we hypothesized that perennial C₃ cover is a major determinant of catt ...

Abstract:
... High concentrations of dissolved inorganic carbon in stems of herbaceous and woody C₃ plants exit leaves in the dark. In the light, C₃ species use a small portion of xylem‐transported CO₂ for leaf photosynthesis. However, it is not known if xylem‐transported CO₂ will exit leaves in the dark or be used for photosynthesis in the light in Kranz‐type C₄ plants. Cut leaves of Amaranthus hypochondriacus ...

Abstract:
... There is great concern about the environmental impact and toxicity of palladium (Pd) because of its widespread use in automotive catalytic converters and other applications. Pd migrates and transforms in the environment and is absorbed by plant roots where it affects plant growth and eventually enters the food chain. Here we explored the effects of Pd on the physicochemical and biochemical charact ...

The stable carbon isotope naturally occurs in carbon-containing compounds and can help determine the origin of the compound in question. In total, 42 types of beers and 11 types of disinfectants were analyz ...
