Abstract/Description
-
In estuaries, like the Indian River Lagoon, mesozooplankton have a vital role in the food web by connecting trophic levels. In this study, mesozooplankton abundance and species composition were monitored weekly on the incoming and outgoing tides from September 2006 to May 2009. For the incoming tide, the mean abundance was 2298.2 mesozooplankton/m3 (+/-325.2), and for the outgoing tide the mean abundance was 1180.0 mesozooplankton/m3 (+/-153.1). The mesozooplankton abundance on the incoming...
Show moreIn estuaries, like the Indian River Lagoon, mesozooplankton have a vital role in the food web by connecting trophic levels. In this study, mesozooplankton abundance and species composition were monitored weekly on the incoming and outgoing tides from September 2006 to May 2009. For the incoming tide, the mean abundance was 2298.2 mesozooplankton/m3 (+/-325.2), and for the outgoing tide the mean abundance was 1180.0 mesozooplankton/m3 (+/-153.1). The mesozooplankton abundance on the incoming tide was significantly greater than on the outgoing tide. The most abundant type of mesozooplankton was the copepod Acartia tonsa, representing 35.0% and 52.1% of the individuals on the incoming and outgoing tides respectively. Mesozooplankton abundance values were compared with environmental data obtained from the South Florida Water Management District. The strongest positive correlation was found between chlorophyll a concentrations and A. tonsa abundance, likely due to phytoplankton being the primary food source for A. tonsa.

Nineteenth century settlers in Florida's Indian River Lagoon (IRL) region created an isolated fringe culture wholly dependent on the instable hydrological forces of the shallow lagoon system. These settlers were among the first to construct a built environment market by the dredging and filling that would define much of the twentieth century Sunshine State. There has been no period when the liminal IRL ecosystem was not without shifting barrier islands and dramatically varying salinity levels...
Show moreNineteenth century settlers in Florida's Indian River Lagoon (IRL) region created an isolated fringe culture wholly dependent on the instable hydrological forces of the shallow lagoon system. These settlers were among the first to construct a built environment market by the dredging and filling that would define much of the twentieth century Sunshine State. There has been no period when the liminal IRL ecosystem was not without shifting barrier islands and dramatically varying salinity levels due primarily to the oceanic interchange following the opening and closing of natural inlets. This paper suggests that attempts to "restore" the lagoon will necessarily declare an arbitrary historical form to be normative for the system. The first and last chapters provide an overview of the system's origins and recent history, while the core of the paper focuses on human-environment interaction of the lagoon in the late nineteenth and early twentieth century.
