Valverde, Angel; Makhalanyane, Thulani Peter; Seely, Mary; Cowan, Don A. (Wiley, 2015-02)Most ecological research on hypoliths, significant primary producers in hyperarid deserts, has focused on the diversity of individual groups of microbes (i.e. bacteria). However, microbial communities are inherently ...

Gunnigle, Eoin; Frossard, Aline; Ramond, Jean-Baptiste; Guerrero, Leandro D.; Seely, Mary; Cowan, Don A. (Nature Publishing Group, 2017-01-10)Microbes in hot desert soil partake in core ecosystem processes e.g., biogeochemical cycling of carbon. Nevertheless, there is still a fundamental lack of insights regarding short-term (i.e., over a 24-hour [diel] cycle) ...

Dube, Joel Prince; Valverde, Angel; Steyn, J.M. (Joachim Marthinus), 1963-; Cowan, Don A. (MDPI, 2019-04-17)Land-use change from natural to managed agricultural ecosystems significantly impacts soil bacterial diversity and function. The Eastern Free State (EFS) is one of the most productive agricultural regions in South Africa. ...
-
Roychoudhury, A.; Cowan, Don A.; Porter, David; Valverde, Alexander (Wiley-Blackwell, 2013-05)Here, we report on the spatial and temporal variation in sulphate-reducing bacterial community structure and activity in three hypersaline coastal pans. Community structure was determined using denaturing gradient gel ...
