11C-autoradiographs to image phloem loading
Hubeau, Michiel; Mincke, Jens; Vanhove, Christian; Gorel, Anaïs Pasiphaé; Fayolle, Adeline; Epila, Jackie; Leroux, Olivier; Vandenberghe, Stefaan; Steppe, Kathy (Frontiers in Forests and Global Change, 2019)Generally, tree species load photoassimilates passively into the phloem, while herbaceous species load actively. These phloem loading strategies have implications for phloem sugar concentration and growth potential. Whereas, ... -
Capacitive water release and internal leaf water relocation delay drought-induced cavitation in African Maesopsis eminii
Epila, Jackie; De Baerdemaeker, Niels J.F.; Vergeynst, Lidewei L.; Maes, Wouter H.; Beeckman, Hans; Steppe, Kathy (Tree physiology, 2017)The impact of drought on the hydraulic functioning of important African tree species, like Maesopsis eminii Engl., is poorly understood. To map the hydraulic response to drought-induced cavitation, sole reliance on the ... -
Drought Effects on Photosynthesis and Implications of Photoassimilate Distribution in 11C-Labeled Leaves in the African Tropical Tree Species Maesopsis eminii Engl.
Epila, Jackie; Hubeau, Michiel; Steppe, Kathy (Forests, 2018)Photoassimilate distribution inside leaves is less studied than photosynthesis, and yet the topic is important as it gives insights into the vital roles played by leaves in plant survival. We combined greenhouse measurements ... -
The ecology of Maesopsis eminii Engl. in tropical Africa
Epila, Jackie; Verbeeck, Hans; Otim-Epila, Thomas; Okullo, Paul; Kearsley, Elizabeth; Steppe, Kathy (African Journal of Ecology, 2017)Maesopsis eminii is referred to as one of the most widely distributed African tree species. However, its occurrence in Africa has never been mapped and little is known as to how this species can sustain in different ... -
Plant measurements on African tropical Maesopsis eminii seedlings contradict pioneering water use behaviour
Epila, Jackie; Maesa, Wouter H.; Verbeeck, Hans; Campa, Janne Van; Okullod, John Bosco Lamoris; Steppe, Kathy (Environmental and Experimental Botany, 2017)With increased drought events affecting forests globally, little is known about their future impact on Africa’s forests. In particular, we need to gain a better understanding of how key African forest species will respond ...
