Contrasting assembly processes in a bacterial metacommunity along a desiccation gradient

Valverde, Alexander; Makhalanyane, Thulani P.; Cowan, Don A. (Frontiers Research Foundation, 2014-12)

Understanding the relative influence of deterministic and stochastic processes in driving community assembly is a major goal in microbial ecology. Here, we have investigated the influence of these processes on bacterial ...
Dissimilatory sulphate reduction in hypersaline coastal pans : an integrated microbiological and geochemical study

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 ...
Effects of high-volume, rapid-fluid therapy on cardiovascular function and hematological values during isoflurane-induced hypotension in healthy dogs

Valverde, Alexander; Gianotti, Giacomo; Rioja-Garcia, Eva; Hathway, Amanda (Canadian Veterinary Medical Association, 2012)

The objective of this study was to determine the effects of the administration of a high volume of isotonic crystalloid at a rapid rate on cardiovascular function in normovolemic, isoflurane-anesthetized dogs during induced ...
