Bacterial cellulases are drawing increased attention as a means to obtain plentiful chemical feedstocks and fuels from renewable lignocellulosic biomass sources. Certain bacteria deploy a large extracellular multi-protein complex, called the cellulosome, to degrade cellulose. Scaffoldin, a key non-catalytic cellulosome component, is a large protein containing a cellulose-specific carbohydrate-binding module and several cohesin modules which bind and organize the hydrolytic enzymes.

The Amazon and Atlantic Forest are considered the world's most biodiverse biomes. Human and climate change impacts are the principal drivers of species loss in both biomes, more severely in the Atlantic Forest. In response to species loss, the main conservation action is the creation of protected areas (PAs). Current knowledge and research on the PA network's conservation efficiency is scarce, and existing studies have mainly considered a past temporal view. In this study, we tested the...

Understanding carbon (C) stocks or biomass in forests is important to examine how forests mitigate climate change. To estimate biomass in stems, branches and roots takes intensive fieldwork to uproot, cut and weigh the mass of each component. Different models or equations are also required. Our research focussed on the dry tropical Zambezi teak forests and we studied their structure at three sites following a rainfall gradient in Zambia. We sampled 3558 trees at 42 plots covering a combined...

Higher temperatures and reduced rainfalls that are expected with the advance of climate change can impair the emergence and establishment of tree seedlings in forest ecosystems. These climatic changes can also decrease the availability of soil resources and reduce the performance of seedlings.

As recently emerged oak seedlings are highly sensitive to changing...

Changes in precipitation due to climate change are likely to influence soil organic matter (SOM) decomposition and stabilization. In forests, increased tree species diversity could modulate the effects of drought on SOM decomposition and stabilization. We addressed this issue by a decomposition study under simulated drought (through precipitation reduction at Zedelgem, Belgium) and natural drought (ORPHEE, southern France) in young experimental plantations (tree species richness 1 to 5).

In river basin systems, power asymmetry is often responsible of inefficient and unbalanced water allocations. Climate change and anthropogenic pressure will possibly exacerbate such disparities as the dominant party controls an increasingly limited shared resource.

This often implies the intervention of a...

Hydrologic model input datasets such as climate, land use, elevation, soil, and geology information are available in a range of scales for use in water resources investigations. Smaller spatial and temporal scale input data allow groundwater recharge models to simulate more physically realistic processes and presumably result in more accurate estimates of groundwater recharge. Projected climate data are, therefore, often downscaled to smaller spatial and temporal scales for use in these models....

Both elevated atmospheric carbon dioxide (CO 2 ) and rising temperature can alter soil methane (CH 4 ) fluxes, leading to a feedback to climate change. However, predicting this feedback needs to understand the microbial mechanisms involved in CH 4 emissions driven by climate change. A 3-year field measurement of CH 4 fluxes from rice paddies was taken in 2012–2014 to examine their responses to elevated CO 2 (enriched up to 500 μmol mol −1 ) and rising canopy air temperature (above ambient...

Climate change is predicted to result in more severe weather events, including drought, which will affect forage production in agricultural grasslands. We evaluated the effects of an experimentally imposed drought on yields of monocultures and mixtures of intensively managed grassland communities comprising four species with contrasting functional traits (Lolium perenne L., Cichorium intybus L., Trifolium repens L., Trifolium pratense L.).

Agriculture across the temperate zone is dominated by a maize-soybean rotation (MSR) characterized by a “leaky” nitrogen (N) cycle. MSR N losses have considerable negative impacts on water quality via N leaching and climate change via soil emissions of nitrous oxide (N 2 O), a potent greenhouse gas. Alley cropping (AC) focused on food- or fodder-producing tree crops has the potential to substantially reduce environmental N losses while maintaining agricultural productivity. To compare the N...

One of the foreseeable consequences of climate change is a reduction in crop yields. In recent years, agroforestry systems have been identified as a strategy for climate change mitigation and adaptation.

We studied a 9-year-old hybrid walnut silvoarable system (Juglans x intermedia Mj209xRa) intercropped with cultivars of two winter cereals – wheat (Triticum aestivum L.) and barley...

No-tillage (NT) has been touted as one of several climate-smart agriculture (CSA) management practices that improve food security and enhance agroecosystem resilience to climate change.

Such trade-offs are regulated by climate fluctuations and heterogeneous soil conditions and have not been well addressed....

Global climate change with elevated atmospheric CO2 concentration and temperature has been known impacting plant photosynthesis and grain yield in agroecosystems. However, how nutrient uptake and utilization by rice change under climate change stresses has been poorly addressed. An open-air field experiment was conducted to investigate the impacts of factorial combinations of CO2 enrichment (up to 500 ppm) and canopy warming (+2 °C) on nutrient concentration (PNC), accumulation (PNA) and...

Deciphering climatic factors limiting cambial activity is critical to forecast the potential of trees to respond to ongoing climatic change. We explored multiple xylem traits, including tree-ring width, inter-annual microdensity variation and intra-annual density fluctuations (IADF), to unveil the climatic factors constraining cambial activity of a Mediterranean conifer (Pinus pinaster) along a continental-aridity gradient. Secondary growth responded mainly to water availability, explaining as...

Shifts in the timing of autumnal leaf coloration and leaf drop in temperate forests with climate change can have substantial impacts on community and ecosystem processes (e.g. altered carbon/nitrogen cycling and biotic interactions). However, the environmental control of autumn phenology remains significantly understudied in striking contrast to spring phenology. In this study, we used linear mixed effects model with ground-based phenology observations in northeastern USA and found that both...

Climate change is influencing tree phenology, causing earlier and more prolonged canopy closure in temperate forests. Canopy closure is closely associated with understorey light, so shifts in its timing have wide-reaching consequences for ecological processes in the understorey. Widespread monitoring of forest canopies through time is needed to understand changes in light availability during spring in particular. Canopy openness, derived from hemispherical photography, has frequently been used...

Converting natural forests to intensively managed plantations markedly alters soil carbon (C) dynamics. However, the impact of such land-use change on soil respiration (RS) components remains unclear. The objective of this study was to examine the effect on RS, autotrophic respiration (RA) and heterotrophic respiration (RH) of converting a natural evergreen broadleaf forest to an intensively managed Moso bamboo (Phyllostachys edulis) plantation. A two-year field study was carried out to assess...
