Regenerative Agriculture - A Literature Review On The Practices And Mechanisms Used To Improve Soil Health, Ravjit Khangura, David Ferris, Cameron Wagg, Jamie Bowyer
Natural Resources Research Articles
Conventional farming practices can lead to soil degradation and a decline in productivity. Regenerative agriculture (RA) is purported by advocates as a solution to these issues that focuses on soil health and carbon sequestration. The fundamental principles of RA are to keep the soil covered, minimise soil disturbance, preserve living roots in the soil year round, increase species diversity, integrate livestock, and limit or eliminate the use of synthetic compounds (such as herbicides and fertilisers). The overall objectives are to rejuvenate the soil and land and provide environmental, economic, and social benefits to the wider community. Despite the purported benefits …

Diversity, Distribution, And Methodological Considerations Of Haemosporidian Infections Among Galliformes In Alaska, Faith De Amaral, Robert E. Wilson, Sarah A. Sonsthagen, Ravinder Sehgal
School of Natural Resources: Faculty Publications
Using samples spanning 10-degrees of latitude in Alaska, we provide the first comparative assessment of avian haemosporidia distribution of Arctic Alaska with subarctic host populations for four species of grouse and three species of ptarmigan (Galliformes). We found a high overall prevalence for at least one haemospordian genus (88%; N = 351/400), with spruce grouse (Canachites canadensis) showing the highest prevalence (100%; N = 54/ 54). Haemoproteus and Plasmodium lineages were only observed within grouse, while Leucocytozoon species were found within both grouse and ptarmigan. Further, different Leucocytozoon lineages were obtained from blood and tissue samples from the …

There have been many scientific advances regarding future sea-level projections, however it is unclear if these have been transferred to assessment reports used by stakeholders. Here, we present a first-of-its-kind comprehensive analysis of regional sea-level rise (SLR) assessments for the United States (U.S.). We identify variations in time horizons over which regions plan for SLR, with 25 projections from the U.S. Northeast and West that extend to 2150 or beyond, but no projections from the U.S. South beyond 2100. The majority of 2100 projections from the U.S. Northeast (77%) and West (83%) include ranges of future SLR, while 88% of …

Nebraska Water Center: Faculty Publications
Interpreting time domain reflectometry (TDR) waveforms obtained in soils with non-uniform water content is an open question. We design a new TDR waveform interpretation model based on convolutional neural networks (CNNs) that can reveal the spatial variations of soil relative permittivity and water content along a TDR sensor. The proposed model, namely TDR-CNN, is constructed with three modules. First, the geometrical features of the TDR waveforms are extracted with a simplified version of VGG16 network. Second, the reflection positions in a TDR waveform are traced using a 1D version of the region proposal network. Finally, the soil relative permittivity values …

Assessing The Effectiveness Of Integrated Multi-Trophic Aquaculture For Growing West Coast Venus Clams, Avery Wallace
Assessing The Effectiveness Of Integrated Multi-Trophic Aquaculture For Growing West Coast Venus Clams, Avery Wallace
Theses
With demand for sustainable sources of seafood on the rise, California is looking to expand aquaculture with a focus on innovative culturing methods and use of native or resident species. Therefore, this study examined the potential for culturing native North American west coast venus clams (Chione californiensis and Chione undatella) using integrated multi-trophic aquaculture (IMTA). An ITMA approach was chosen because it is a culture method that uses species from different but functionally complementary trophic levels that have been found to reduce the potential negative effects of traditional monoculture. California sea cucumber (Parastichopus californicus) and the seaweeds red ogo (Gracilaria …

Shale Oil Development And Utilization And Its Role In Energy Industry, Xusheng Guo, Maowen Li, Mengyun Zhao
Shale Oil Development And Utilization And Its Role In Energy Industry, Xusheng Guo, Maowen Li, Mengyun Zhao
Bulletin of Chinese Academy of Sciences (Chinese Version)
Shale oil boom in the United States has catapulted it from an importer of crude oil to a net exporter. Field applications show that both the shift in exploration paradigm from finding traps to targeting resource-rich petroleum source kitchens (i.e., "sweet spots") and the technological innovation represented by horizontal well multi-stage fracturing are among the key factors for the large-scale development of shale oil in the United States. Compared with marine shale oils in North America, China's lacustrine shale oil resources have great potential, but the endowment conditions are not optimal. Early exploration and development experience shows that the adaptive …

Mission Of New Energy Under Carbon Neutrality Goal In China, Caineng Zou, Yanpeng Chen, Bo Xiong, Hanlin Liu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Reducing greenhouse gas emissions, curbing the global temperature rise, and striving to achieve the goal of carbon neutrality are the initiatives and common pursuit of human beings confronting the climate change crisis. Carbon neutrality is a huge systemic project involving multiple disciplines and fields, and it requires a solid theoretical foundation and scientific methods to achieve the goal of carbon neutrality, hence the emergence of carbon neutrality science. The theoretical connotation of carbon neutrality includes two "dynamic balances", namely, the dynamic balance between global carbon emission and carbon absorption, and the dynamic balance between human development and the natural environment, …

Developing Ecological Security Pattern For Coastal Wetlands Based On “Three-Line Integration” Spatial Strategy, Xiaowen Li, Liehui Zhi, Tiantian Ma, Zengli Liu, Baoshan Cui, Dongdong Shao, Yu Cao, Yonglin Mu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Coastal wetlands function as key socioeconomic resources as well as ecological barriers for sustainable development in coastal regions. Although previous research and practices indicate that restoration of degraded wetlands needs combination with intact natural wetlands to achieve best integrated ecosystem services, this kind of integration is still lacking both in research and practice. In the past decades, increased land reclamation coupling with climate change (e.g. sea level rise) have led considerable coastal squeeze effects and intensified degradation and loss in coastal wetlands along Chinese coastline, restoration of damaged coastal wetlands is therefore urgently needed to enhance the overall ecological functions …
