“…Previous studies have characterized nutrient dynamics within Everglades communities and/or landscapes (e.g. Orem et al 2002;Jayachandran et al 2004;Ross et al 2006;Wetzel et al 2009), but few have employed a multi-scale approach. In this study we aimed to analyze the spatial variability and patterning of nutrients in relation to cross-scale site parameters within and among two hydrologically defined Everglades landscapes; the freshwater Marl Prairie and the Ridge and Slough.…”

The freshwater Everglades is a complex system containing thousands of tree islands embedded within a marsh-grassland matrix. The tree islandmarsh mosaic is shaped and maintained by hydrologic, edaphic and biological mechanisms that interact across multiple scales. Preserving tree islands requires a more integrated understanding of how scale-dependent phenomena interact in the larger freshwater system. The hierarchical patch dynamics paradigm provides a conceptual framework for exploring multiscale interactions within complex systems. We used a three-tiered approach to examine the spatial variability and patterning of nutrients in relation to site parameters within and between two hydrologically defined Everglades landscapes: the freshwater Marl Prairie and the Ridge and Slough. Results were scaledependent and complexly interrelated. Total carbon and nitrogen patterning were correlated with organic matter accumulation, driven by hydrologic conditions at the system scale. Total and bioavailable phosphorus were most strongly related to woody plant patterning within landscapes, and were found to be 3 to 11 times more concentrated in tree island soils compared to surrounding marshes. Below canopy resource islands in the slough were elongated in a downstream direction, indicating soil resource directional drift. Combined multi-scale results suggest that hydrology plays a significant role in landscape patterning and also the development and maintenance of tree islands. Once developed, tree islands appear to exert influence over the spatial distribution of nutrients, which can reciprocally affect other ecological processes.

“…Similarly, various authors (Orem et al 2002, Gann Troxler et al, 2001, Wetzel 2009) reported extremely high phosphorous content at the head or center of islands compared with surrounding marsh. The discrepancies between LILA and Everglades tree islands in soil TP content is likely the result of tree island age.…”

“…Soil accretion at the tail of LILA tree islands could be the beginning of the process of tail elongation that can be seen in natural tree islands, however this process can take a long time. Willard et al (2002) reported that maturation of the Gumbo Limbo and Nuthouse tree islands located in the Water Conservation Area (WCA) 3B took between 1000 and 2000 years.…”

“…Tree islands are considered a biogeochemical hotspot because of their higher nutrient concentration compared to the surrounding marsh, and high rate of nutrient cycling (Wetzel et al, 2005;Orem et al, 2002). Tree island soil pH is lower than marsh soil .…”
