Modelling vegetation understory cover using LiDAR metrics

PLOS ONE, 2019
AbstractForest understory vegetation is an important feature of wildlife habitat among other things. Predicting and mapping understory is a critical need for forest management and conservation planning, but it has proved difficult. LiDAR has the potential to generate remotely sensed forest understory structure data, yet this potential has to be fully ...

Fermented Lacticaseibacillus Paracasei Cultures Ameliorate Colitis by Modulating Microbiota‐Derived Tryptophan Metabolism and Macrophage Polarization

Advanced Science, EarlyView.
A solid‐state fermented probiotic (PYW) is developed using wheat bran as substrate, containing high viable Lacticaseibacillus paracasei and bioactive metabolites. PYW alleviates intestinal inflammation by gut microbiota composition, enriching indole derivatives, activating aryl hydrocarbon receptor signaling, and regulating macrophage polarization. PYW

A Trypsin‐Like Serine Protease ZmNAL1a Fine‐Tunes Maize Floral Transition and Flowering Time

Advanced Science, EarlyView.
This study identifies a trypsin‐like serine protease, ZmNAL1a, that moves from leaves to the shoot apical meristem. ZmNAL1a promotes the floral transition by degrading TOPLESS‐like corepressor REL2, which thereby enhances the expression of key flowering genes through elevating histone acetylation and relieving REL2–ZmEREBP147‐mediated transcriptional ...

Azolla filiculoides extract improved salt tolerance in wheat (Triticum aestivum L.) is associated with prompting osmostasis, antioxidant potential and stress-interrelated genes

Scientific Reports
The growth and productivity of crop plants are negatively affected by salinity-induced ionic and oxidative stresses. This study aimed to provide insight into the interaction of NaCl-induced salinity with Azolla aqueous extract (AAE) regarding growth ...

Grazing impact on soil chemical and biological properties under different plant cover types in a mountain area of Southern Italy. [PDF]

, 2006
Grazing can contribute to soil degradation by compaction due to roaming of livestock and loss of herbaceous cover, affecting also soil microbial community.

The role of land cover change in Arctic-Boreal greening and browning trends [PDF]

, 2019
Many studies have used time series of satellite-derived vegetation indices to identify so-called greening and browning trends across the northern high-latitudes and to suggest that the productivity of Arctic-Boreal ecosystems is changing in response to ...

Chloroplast Stress Signals Orchestrate Epidermis‐Specific Remodeling of Mitochondria and ER Under High Light

Advanced Science, EarlyView.
High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.

Environmental effects of the Manganui ski field, Mt Taranaki/Egmont [PDF]

, 2012
During May 2012, the environmental effects of the Manganui ski field were examined. Permanent quadrats first established in 1974 to monitor vegetation changes were re-measured, vegetation mapping was conducted, modifications to ground form and drainage ...
