Sediment biogeochemistry

Sediment biogeochemistry in mangrove forests is just as complex as water column biogeochemistry. The sediments are highly heterogenic and the

Peter Teasdale, Ph.D., is a senior lecturer in environmental chemistry at Australian Rivers Institute, Griffith University Gold Coast Campus. His current research interests include in situ sensors for metals and nutrients, natural, recycled and potable water quality, microbial toxicology, and sediment biogeochemistry. Peter is the current chair of the Royal Australian Chemical Institute Environment Division. He has published over 40 refereed publications. Coauthoring this book reflects his interest in the field of conducting electroactive polymers, the area in which he completed his Ph.D. in 1993 at the University of Wollongong. 

Rates of nutrient transformation and recycling are presumably also dependent on forest type and age, but only few studies have examined the influence of forest type (Alongi etal., 1993, 1998 Middelburg etal., 1996). Early studies have suggested that some edaphic characteristics are species-specific (Nickerson Thibodeau, 1985), but subsequent studies have shown that apparent differences between forest types are more closely related to root density and frequency of tidal inundation than to species-specific ability of mangroves to affect sediment biogeochemistry and nutrient turnover (McKee etal, 1988). Nevertheless,...
