This could be that the addition of chelating ligand complexed both metallic species retarding sulfidation of both metals, hence lowering the HDS activity. Studies show that it is possible for the citric acid to complex with both promoter and an active metal (Mo), and this might result in the formation of molybdenum dimers, trimers and tetramers which are difficult to sulfide.

A strong linear relationship between dNBR and stem fire severity (r2 = 0.69, p < 0.001) confirmed the accuracy of dNBR as a measure of fire severity in Afrotemperate forest. In the fire investigated, 4 628 ha of Afrotemperate forest burnt of which 67% burnt at low severity, 21% at medium severity and 12% at high severity. The dNBR values associated with fire severity categories were comparable between Afrotemperate and North American forests, suggesting that dNBR values are relatively standard across forest types. Information on the distribution of fire severity facilitates investigation of further questions regarding past and future fire regimes and the fire ecology of Afrotemperate forest. The post-fire survival rate of Afrotemperate forest trees was 45% which is comparable to that in coniferous forests of North America but lower than that in temperate forests of Australia and Portugal and the neighbouring dune thicket which shares several species with Afrotemperate forest. Fire severity had a significant negative effect on survival and tree size a significant positive effect. Total variance explained by the model (for species collectively) was 40.8%, of which fire severity and tree size combined explained 13.2%, and species as random factor, 27.6%. Respective tree species showed differential survival responses – four species showed high survival (> 60% of individuals), while five species showed low survival (< 40%). This study was the first post-fire assessment of the resprouting ability of Afrotemperate forest trees and a third of the trees surveyed (for species collectively) resprouted from the stem. This suggested that resprouting from the stem is a primary means of post-fire recovery in Afrotemperate forest trees, in contrast with previous assertions that several common canopy species, including Podocarpus latifolius, Afrocarpus falcatus, Scutia myrtina, Scolopia mundii and Rapanea melanophloeos, are unable to resprout. Varying resilience to fire among species supports previous suggestions that fire affects species’ composition and diversity in these forests and calls for careful management of fire regimes in the face of global change.]]> Thu 09 Jun 2022 16:02:39 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:49588 Thu 07 Apr 2022 10:29:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:49586 Thu 07 Apr 2022 10:00:36 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46022 Thu 03 Feb 2022 13:55:30 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45691 Mon 31 Jan 2022 13:44:08 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45134 Mon 22 Nov 2021 10:53:57 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45140 Mon 22 Nov 2021 10:04:56 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45139 Mon 22 Nov 2021 09:20:55 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:52374 Mon 14 Nov 2022 08:43:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46584 Mon 14 Feb 2022 15:39:48 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46577 Mon 14 Feb 2022 15:26:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46541 Mon 14 Feb 2022 12:03:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:46517 Mon 14 Feb 2022 10:36:11 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:52017 Mon 13 Jun 2022 12:24:52 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45688 Fri 28 Jan 2022 11:06:50 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45683 Fri 28 Jan 2022 10:32:56 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45682 Fri 28 Jan 2022 09:32:18 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45686 Fri 28 Jan 2022 09:28:09 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45685 Fri 28 Jan 2022 09:25:32 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45684 Fri 28 Jan 2022 09:22:49 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:48830 Fri 25 Mar 2022 12:24:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:48823 Fri 25 Mar 2022 10:46:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:45141 Sr>Ca.
