Abstract We present stationarity criteria for forest stands, and establish embodiments using a Norwegian empirical stand development model. The natural stationary states only slightly differ from the outcome of long-term simulations previously implemented using the same empirical model. Human interference in terms of diameter-limit cutting is introduced. Consequently, stationar...
Abstract Windbreaks were originally promoted across the U.S. Great Plains to reduce wind erosion. A review paper published nearly 30 years ago showed yield increases for a variety of crops associated with windbreaks. However, with the widespread use of no-till cropping systems and advanced crop genetics, the question is “Do windbreaks still provide a yield benefit?” This s...
Abstract There is increasing interest in the potential of agroforestry to improve the productivity and sustainability of coffee production, but designing management options is knowledge intensive. Tree-crop interactions and the biophysical and socio-economic factors influencing farmers’ decision-making about companion trees are complex and context-specific but fine scale data...
Abstract We embraced the “learning from nature and back to nature” paradigm to develop viable agroforestry scenarios through studying species association in 12 wild yellowhorn (Xanthoceras sorbifolium: a Chinese endemic oil woody plants) communities. We identified 18 species combinations for their suitability as agroforestry mixes where positive associations were detected a...
Abstract During mechanized forest operations, machines with high wheel loads are operated directly on the soil and can pose serious concerns for the integrity and quality of soil properties. Simply relying on absolute soil density (g cm−3 or t m−3) as a measure of qualitative assessment remains site specific. Instead of absolute soil density, the aim of this study was to ...
Abstract This study focusses on the fractionation of proteins and lipids from insect biomass, more specifically from black soldier fly larvae. Insects are rich in proteins and lipids and offer potential as a protein source for food and feed. Fractionation processes often focus on extracting only one compound (lipid or protein), neglecting the impact of the extraction method on ot...

Publication date: 1 October 2019Source: Forest Ecology and Management, Volume 449Author(s): Cathryn H. Greenberg, Tara L. Keyser, W. Henry McNab, Patrick ScottAbstractUpland hardwood forest managers are increasingly burning during the growing-season in hopes of improving wildlife habitat and attaining or accelerating other restoration goals, highlighting the need for research addressing how season...

Publication date: 1 October 2019Source: Forest Ecology and Management, Volume 449Author(s): Xianyu Yao, Yuanfa Li, Liangning Liao, Guo Sun, Hongxiang Wang, Shaoming YeAbstractThere is substantial evidence that legume-derived nitrogen (N) is transferred to neighboring nonlegumes in herbaceous mixtures and intercropping systems. However, considering that woody species are key sources and major consu...
Publication date: 1 October 2019Source: Forest Ecology and Management, Volume 449Author(s): Yanrong Guo, Changhui Peng, Ralph Trancoso, Qiuan Zhu, Xiaolu ZhouAbstractClimate and soil factors drive forest carbon (C) density. However, their impacts on the aboveground carbon density (ACD) and belowground carbon density (BCD) of global forest types have not been quantified in previous studies. In this...
