Woodborne, Stephan M.; Hall, Grant; Robertson, Iian; Patrut, Adrian; Rouault, Mathieu; Loader, Neil R.; Hofmeyr, Michele (Public Library of Science, 2015-05-13)A proxy rainfall record for northeastern South Africa based on carbon isotope analysis of four baobab (Adansonia digitata L.) trees shows centennial and decadal scale variability over the last 1,000 years. The record is ...

Woodborne, Stephan M.; Hall, Grant; Jones, Connor W.; Loader, Neil R.; Patrut, Adrian; Patrut, Roxana T.; Robertson, Iain; Winkler, Stephan R.; Winterbach, Christiaan W. (Studia Universitatis Babes-Bolyai, 2018)Climate records along aridity gradients where manifestations of climate change are most profound are important for testing climate models. The Kalahari Transect spans such a gradient, but instrumental records of ...

Patrut, Adrian; Woodborne, Stephan M.; Von Reden, Karl F.; Hall, Grant; Hofmeyr, Michele; Lowy, Daniel A.; Patrut, Roxana T. (Public Library of Science, 2015-01)The article reports the radiocarbon investigation results of the Lebombo Eco Trail tree, a representative African baobab from Mozambique. Several wood samples collected from the large inner cavity and from the outer part ...

Patrut, Adrian; Woodborne, Stephan M.; Patrut, Roxana T.; Hall, Grant; Rakosy, Laszlo; Winterbach, Christiaan; Von Reden, Karl F. (MDPI Publishing, 2019-11-05)The year 2016 witnessed the fall of a symbol of the botanical world: the historic Chapman baobab of Botswana. This article presents the results of our investigation of the standing and fallen tree. The Chapman baobab ...

Wils, Tommy H.G.; Robertson, Iain; Woodborne, Stephan M.; Hall, Grant; Koprowski, Marcin; Eshetu, Zewdu (Wiley, 2016-05)Rising atmospheric CO2 concentrations affect climate directly through radiative effects and indirectly by changing plant water-use efficiency. Under global warming scenarios these widely reported changes will have ...

Conradie, Shannon Rose; Woodborne, Stephan M.; Wolf, Blair O.; Pessato, Anais; Mariette, Mylene M.; McKechnie, Andrew E. (Society for Experimental Biology, 2020-06)Intense heat waves are occurring more frequently, with concomitant increases in the risk of catastrophic avian mortality events via lethal dehydration or hyperthermia. We quantified the risks of lethal hyperthermia and ...

Patrut, Adrian; Woodborne, Stephan M.; Patrut, Roxana T.; Rakosy, Laszlo; Lowy, Daniel A.; Hall, Grant; Von Reden, Karl F. (Nature Publishing Group, 2018-07)The African baobab is the biggest and longest-living angiosperm tree. By using radiocarbon dating we identified the stable architectures that enable baobabs to reach large sizes and great ages. We report that 9 of the 13 ...

Pietersen, Darren William; Symes, Craig Thomas; Woodborne, Stephan M.; McKechnie, Andrew E.; Jansen, Raymond (Wiley, 2016-03)The diet of Temminck’s ground pangolin Smutsia temminckii (hereafter, pangolin) has thus far been studied only in mesic savannahs. We provide arid-zone dietary data for this species based on direct observations, and ...

Smit, Ben; Woodborne, Stephan M.; Wolf, Blair O.; McKechnie, Andrew E. (Oxford University Press, 2019-01)The scarcity of free-standing water sources is a key determinant of animal and plant community structure in arid environments, and an understanding of the extent to which particular species use surface water is vital for ...

Patrut, Adrian; Woodborne, Stephan M.; Patrut, Roxana T.; Rakosy, Laszlo; Hall, Grant; Ratiu, Ileana-Andreea; Von Reden, Karl F. (Studia Universitatis Babes-Bolyai, 2017)The article discloses the main results of our new investigation of Platland tree, a.k.a. Sunland baobab, the largest known African baobab. Our recent research was motivated by the three successive splits of 2016 and ...

Patrut, Adrian; Woodborne, Stephan M.; Von Reden, Karl F.; Hall, Grant; Patrut, Roxana T.; Rakosy, Laszlo; Danthu, Pascal; Leong Pock-Tsy, Jean-Michel; Lowy, Daniel A.; Margineanu, Dragos (Cambridge University Press, 2017-04)The article reports the growth stop phenomenon, which was documented only for baobabs, i.e. for trees belonging to the Adansonia genus. The identification of growth stop was enabled by radiocarbon dating, which allows a ...

Robb, Gillian N.; Woodborne, Stephan M.; De Bruin, Phillippus Rudolf; Medger, Katarina; Bennett, Nigel Charles (NRC Research Press, 2015-03)Stable isotope analysis is frequently applied as a tool to examine dietary patterns in animals. However, some of the underlying assumptions associated with using this approach are increasingly being questioned. We carried ...

Adlam, Amanda L.; Chimimba, Christian Timothy; Retief, D.C. Hugo; Woodborne, Stephan M. (Academy of Science of South Africa, 2022-07)Freshwater systems in southern Africa are under threat of climate change, not only from altered flow regimes as rainfall patterns change, but also from biologically significant increases in water temperature. Statistical models ...

Monadjem, Ara; Kane, Adam; Taylor, Peter; Richards, Leigh R.; Hall, Grant; Woodborne, Stephan M. (Royal Society Publishing, 2018-12)Bats play important ecological roles in tropical systems, yet how these communities are structured is still poorly understood. Our study explores the structure of African bat communities using morphological characters ...

Ramond, Jean-Baptiste; Woodborne, Stephan M.; Hall, Grant; Seely, Mary; Cowan, Don A. (Nature Publishing Group, 2018-05-02)Carbon exchange in drylands is typically low, but during significant rainfall events (wet anomalies) drylands act as a C sink. During these anomalies the limitation on C uptake switches from water to nitrogen. In the ...
