Soil Degradation Mapping in Drylands Using Unmanned Aerial Vehicle (UAV) Data

Soil Systems, 2019
Arid and semi-arid landscapes often show a patchwork of bare and vegetated spaces. Their heterogeneous patterns can be of natural origin, but may also indicate soil degradation.

Soils and their radiometric characteristics [PDF]

, 2016
The Tellus airborne geophysical data sets provide impetus to many new lines of research. The radiometric data, conventionally used for bedrock investigations, have recently been used to support regional mapping of peat extent and thickness, and thus ...

Bacteria and Fungi Synergistically Reprogram Flavonoid Metabolites in the Pericarp of Citrus Reticulata 'Chachi' During Storage

Advanced Science, EarlyView.
The authors employed widely targeted metabolomics, microbial amplicon sequencing, and fermentation assays to investigate the microbiome 's influence on PCRC 's (pericarp of Citrus reticulata ' Chachi ') flavonoid profile over 0–19 years of storage. Based on the correlation analysis, solid‐state and liquid‐state fermentation, and catalytic activity ...

A study of the usefulness of Skylab EREP data for earth resources studies in Australia [PDF]

The author has identified the following significant results. In subhumid, vegetated areas, S190B photography: (1) has a potentially operational role in detecting lineaments in 1:100,000 scale geological mapping and in major civil engineering surveys; (2)

The Osteoblastic Microenvironment Determines the Fate of Breast Cancer Cells Disseminated in the Bone Marrow

Advanced Science, EarlyView.
This study revealed how the osteoblastic microenvironment determines the fate of cancer cells disseminated in bone, with a focus on whether they colonize, reside in quiescence, or reactivate from dormancy. Targeting integrin signaling may offer promising strategies for preventing quiescent cancer cells reactivation and bone colonization.

Divergent Responses of Bacterial Communities to Permafrost Degradation and Their Associations With Carbon Across Vertical Profiles

Advanced Science, EarlyView.
Bacterial α‐diversity decreases, but stochasticity and community stability increase across the 15 m‐depth vertical profiles and along the degraded gradient within the active layer. The abundance and interaction of core taxa mainly control community stability in the active and permafrost layers, respectively.
