Biophysical effects from deforestation have the potential to amplify carbon losses but are often neglected in carbon accounting systems. Here we use both Earth system model simulations and satellite-derived estimates of aboveground biomass to assess losses of vegetation carbon caused by the influence of tropical deforestation on regional climate across different continents. In the Amazon, warming and drying arising from deforestation result in an additional 5.1 ± 3.7% loss of aboveground biomass. Biophysical effects also amplify carbon losses in the Congo (3.8 ± 2.5%) but do not lead to significant additional carbon losses in tropical Asia due to its high levels of annual mean precipitation. These findings indicate that tropical forests may be undervalued in carbon accounting systems that neglect climate feedbacks from surface biophysical changes and that the positive carbon-climate feedback from deforestation-driven climate change is higher than the feedback originating from fossil fuel emissions.

Background: Plant diseases cause huge losses in agriculture worldwide every year, but the prolonged use of current commercial fungicides has led to the development of resistance in plant pathogenic fungi. Therefore, there is an urgent need to develop new, efficient, and green fungicides.
Results: Twenty-three nootkatone-based thiazole-hydrazone compounds were designed, synthesized, and characterized by Fourier-transform infrared (FTIR), proton (H) nuclear magnetic resonance (NMR), carbon-13 (C) NMR, and high-resolution mass spectrometry (HRMS).

Transforming lignocellulosic biomass waste into value-added materials like porous carbons offers a sustainable and increasingly important solution for its efficient management within a circular economy framework. Although the heteroatom-doping process enhances oxygen- or nitrogen-containing functionalities on porous carbons, it often leads to losses in structural integrity and other key functionalities. This study presents a novel protocol to produce N-doped porous carbons that efficiently introduces nitrogen groups while improving surface area, microporosity definition and the concentration of oxygen-containing functionalities.

Carbon use efficiency (CUE) of microbial communities in soil quantifies the proportion of organic carbon (C) taken up by microorganisms that is allocated to growing microbial biomass as well as used for reparation of cell components. This C amount in microbial biomass is subsequently involved in microbial turnover, partly leading to microbial necromass formation, which can be further stabilized in soil. To unravel the underlying regulatory factors and spatial patterns of CUE on a large scale and across biomes (forests, grasslands, croplands), we evaluated 670 individual CUE data obtained by three commonly used approaches: (i) tracing of a substrate C by C (or C) incorporation into microbial biomass and respired CO (hereafter C-substrate), (ii) incorporation of O from water into DNA (O-water), and (iii) stoichiometric modelling based on the activities of enzymes responsible for C and nitrogen (N) cycles.

One of the major global concerns is to mitigate carbon dioxide emissions to addressing the detrimental impacts of climate change. Aquatic vegetation, as a natural carbon pool, offers a potential solution to such problems. However, a crucial impediment is the absence of comprehensive estimates of its organic carbon storage.

Vibrio harveyi is a common sort of pathogenic bacterium in marine, which annually gives rise to huge financial losses in aquaculture industry. Flagellin is one of the important virulence factors for bacteria, but meanwhile it is also a preferable vaccine candidate. In this study, we have identified and analyzed two flagellin antigens of V.
