Drivers of inter-annual variability in Net Ecosystem Exchange in a semi-arid savanna ecosystem, South Africa

Author: Archibald, SA ; Kirton, A ; Van der Merwe, Martina R ; Scholes, RJ ; Williams, CA ; Hanan, N Date: 2009 Inter-annual variability in primary production and ecosystem respiration was explored using eddy-covariance data at a semi-arid savanna site in the Kruger Park, South Africa. New methods of extrapolating night-time respiration to the entire ... Read more
An FTIR study on the chlorophyll and apoprotein aggregation states in LHCII due to solvent effects

Author: Smit, Jacoba E ; Prinsloo, LC ; Nel, JM Date: Jul 2012 Photosynthesis provides us with the most abundant and efficient light-harvesting systems found in nature. The photosynthetic process is very much dependent on the aggregation state of the chlorophylls and secondary conformational structure ... Read more
Physiological responses of a fynbos legume, Aspalathus linearis to drought stress

Author: Lotter, D ; Valentine, AJ ; Van Garderen, EA ; Tadross, M Date: Jul 2014 Aspalathus linearis (rooibos) is a medicinally and economically useful shrub which is endemic to the Mediterranean west coast region of South Africa. Species distribution modelling indicates potentially severe consequences in range shift for ... Read more
Precipitation as driver of carbon fluxes in 11 African ecosystems

Author: Merbold, L ; Ardo, J ; Arneth, A ; Scholes, RJ ; Nouvellon, Y ; De Grandcourt, A ; Archibald, SA ; Bonnefond, JM ; Boulain, N ; Bruemmer, C ; Brueggemann, N ; Cappelaere, B ; Ceschia, E ; El-Khidir, HAM ; El-Tahir, BA ; Falk, U ; Lloyd, J ; Kergoat, L ; Le Dantec, V ; Mougin, E ; Muchinda, M ; Mukelabai, MM ; Ramier, D ; Roupsard, O ; Timouk, F ; Veenendaal, EM ; Kutsch, L Date: 2008 This study reports carbon and water fluxes between the land surface and atmosphere in eleven different ecosystems types in Sub-Saharan Africa, as measured using eddy covariance (EC) technology in the first two years of the CarboAfrica network ...

Single-turnover variable chlorophyll fluorescence as a tool for assessing phytoplankton photosynthesis and primary productivity: Opportunities, caveats and recommendations

Author: Schuback, N ; Tortell, PD ; Berman-Frank, I ; Campbell, DA ; Ciotti, A ; Courtecuisse, E ; Erickson, ZK ; Fujiki, T ; Ryan-Keogh, Thomas J ; Thomalla, Sandy J Date: Jul 2021 Phytoplankton photosynthetic physiology can be investigated through single-turnover variable chlorophyll fluorescence (ST-ChlF) approaches, which carry unique potential to autonomously collect data at high spatial and temporal resolution. ...
