U.S. Agriculture, Biofuel Markets, and Trade: Challenges and Opportunities
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Using an enhanced Computable General Equilibrium (CGE) model (GTAP‐BIO), this study assesses how the expansion in demand for Electric Vehicles (EVs) and the reduction in exports of agricultural products induced by trade disputes negatively affect US agriculture.

Trees, Forests and PeopleMany current management approaches in temperate European forests aim to promote forest structural complexity. Yet, the dynamics of three-dimensional forest structure under different silvicultural systems and their impacts on forest microclimate remain ...

Annual litterfall dynamics and nutrient deposition depending on elevation and land use at Mt. Kilimanjaro [PDF]
Biogeosciences, 2015 Litterfall is one of the major pathways connecting above- and below-ground processes. The effects of climate and land-use change on carbon (C) and nutrient inputs by litterfall are poorly known.

American Journal of Botany, EarlyView.Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Index of biodiversity potential (IBP) versus direct species monitoring in temperate forests
Ecological Indicators, 2022 Effects of forest management on forest biodiversity have received increasing attention in both research and forestry practice. Despite advances in technology, monitoring of biodiversity remains time and cost-intensive and requires specific taxonomic ...

Dark microbial CO2 fixation in temperate forest soils increases with CO2 concentration
Global Change Biology, 2019 Dark, that is, nonphototrophic, microbial CO2 fixation occurs in a large range of soils. However, it is still not known whether dark microbial CO2 fixation substantially contributes to the C balance of soils and what factors control this process ...

American Journal of Botany, EarlyView.Abstract Premise The soil depth of underground storage organs (USOs) of geophytes involves cost–benefit trade‐offs and may relate to USO age, size, and disturbances such as fire and herbivory. Yet determinants of USO depth are poorly studied. We posit that belowground mammalian predation of USOs is a selective force for the positive relationship ...

Unravelling the functions of biogenic volatiles in boreal and temperate forest ecosystems
European Journal of Forest Research, 2019 Living trees are the main source of biogenic volatile organic compounds (BVOCs) in forest ecosystems, but substantial emissions originate from leaf and wood litter, the rhizosphere and from microorganisms.
