Mapping and Monitoring Fractional Woody Vegetation Cover in the Arid Savannas of Namibia Using LiDAR Training Data, Machine Learning, and ALOS PALSAR Data por Wessels, Konrad, Mathieu, Renaud, Knox, Nichola, Main, Russell, Naidoo, Laven, Steenkamp, Karen

“…During the seven-year study period the Shrubland–Woodland Mosaic was the only vegetation structural class that exhibited a regional net gain in FWC of more than 0.2 across 9% (11,906 km2) of its area that may potentially be attributed to bush encroachment. FWC change maps provided regional insights and detailed local patterns related to debushing and regrowth that can inform national rangeland policies and debushing programs.…”

RNA-Seq analysis reveals insight into enhanced rice Xa7-mediated bacterial blight resistance at high temperature por Cohen, Stephen P., Liu, Hongxia, Argueso, Cristiana T., Pereira, Andy, Vera Cruz, Casiana, Verdier, Valérie, Leach, Jan E.

“…During some plant-pathogen interactions, heat stress allows pathogens to overcome host resistance, a phenomenon which could severely impact crop productivity considering the global warming trends associated with climate change. Despite the importance of this phenomenon, little is known about the underlying molecular mechanisms. …”

Key crop nutrient management issues in the Western Australia grains industry: a review por Chen, W., Bell, R.W., Brennan, R.F., Bowden, J.W., Dobermann, A., Rengel, Z., Porter, W.

“…To further improve soil testing and interpretation, the review suggests that future research should focus on addressing soil sampling and interpretation questions, as they are important factors affecting the accuracy of fertiliser recommendations with changing cropping practices. There have been several studies to compare fluid with granular forms of P in WA, but the responses have not, so far, been consistent. …”

The influence of increasing carbon dioxide and temperature on competitive interactions between a C3 crop, rice (Oryza sativa) and a C4 weed (Echinochloa glabrescens) por Alberto, AMP, Ziska, LH, Cervancia, CR, Manalo, PA

“…When grown in mixture, the proportion of rice biomass increased significantly relative to that of the C4 weed at all mixtures at elevated CO2. Evaluation of changes in competitiveness (by calculation of plant relative yield (PRY) and replacement series diagrams) of the two species demonstrated that, at elevated CO2, the competitiveness of rice was increased relative to that of E. glabrescens. …”

Influence of Deep Root Density on Root Pulling Resistance in Rice por Ekanayake, I.J., Garrity, D.P., O'Toole, J.C.

“…The rate of increase in RPR was low for the first 24 to 25 days after transplanting, but accelerated greatly after this date in tests over two seasons. This change in the rate of increase may correspond with the time at which the root system penetrates into the firm soil layers below the puddled layer. …”
