Analysis of Kissimmee River floodplain seed dispersal for vegetation community restoration
Title
Analysis of Kissimmee River floodplain seed dispersal for vegetation community restoration.
Creator
Mezza, Garren., Charles E. Schmidt College of Science, Center for Environmental Studies
Abstract/Description
This research examined the influence of hydrochory (seed dispersal via water), anemochory (seed dispersal via wind), and zoochory (seed dispersal by animals) on the re-establishment of the important floodplain vegetation communities of the Kissimmee River floodplain. Fifty-eight seed species were identified from 19,849 and 43, 894 seeds trapped in hydrochory traps in sites north and south of Oak Creek, respectively. Seeds trapped by anemochory were measurable but were found to be far less...

Fifty-eight seed species were identified from 19,849 and 43, 894 seeds trapped in hydrochory traps in sites north and south of Oak Creek, respectively. Seeds trapped by anemochory were measurable but were found to be far less important than hydrochory, while results showed no evidence of zoochory .... A number of interafting factors, e.g. hydrology, lack of remnants, seed phenology, etc. are limiting the dispersal of broadleaf marsh species north of Oak Creek, delaying range, expansion, and further community restoration.

Spatio-temporal modeling of seed dispersal and aquatic plant community restoration in the Kissimmee River floodplain.
Creator
Kennard, Stevee., Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description
This study created an ecological spatial model, using a geographic information system, to visualize the influence of hydrochory on restoration of the three dominant wetland communities of broadleaf marsh, wetland shrub, and wet prairie across the floodplain of the Kissimmee River. Primary parameters incorporated into the model included floodplain hydrology, seed characteristics of buoyancy and dispersal rates, and species flood tolerance. S²rensen's similarity index, comparing spatial...
Show moreThis study created an ecological spatial model, using a geographic information system, to visualize the influence of hydrochory on restoration of the three dominant wetland communities of broadleaf marsh, wetland shrub, and wet prairie across the floodplain of the Kissimmee River. Primary parameters incorporated into the model included floodplain hydrology, seed characteristics of buoyancy and dispersal rates, and species flood tolerance. S²rensen's similarity index, comparing spatial agreement among model output and observed community data, resulted in values of BLM-BB = 0.10, BLM = 0.07, WS = 0.21, and WP = 0.36. The significant discrepancies between modeled and observed community spatial coverage indicated a need for incorporation of more stochastic variables of climatic disturbances, nutrient availability, and soil characteristics. More research on species flood tolerance across smaller spatial scales is also needed, and base data incorporated into the model should also be reliable and consistent if accuracy is to be achieved.

Floodplain habitat use and movements of two centrarchids within pool B of the Kissimmee River, Florida.
Creator
Giles, Matthew Justin, Florida Atlantic University, Courtenay, Walter R. Jr., Wilzbach, Margaret A.
Abstract/Description
Floodplains are important elements of river-floodplain systems. Numerous riverine fishes utilize floodplain habitats for reproduction, feeding, and protection. Largemouth bass and bluegill sunfish were tracked using radiotelemetry, and environmental parameters were measured at fish locations. Bass and bluegill used habitats with the same physical and chemical characteristics. Floodplain habitats were utilized frequently, as much as main river channel habitats. Fishes used habitats dominated...
Show moreFloodplains are important elements of river-floodplain systems. Numerous riverine fishes utilize floodplain habitats for reproduction, feeding, and protection. Largemouth bass and bluegill sunfish were tracked using radiotelemetry, and environmental parameters were measured at fish locations. Bass and bluegill used habitats with the same physical and chemical characteristics. Floodplain habitats were utilized frequently, as much as main river channel habitats. Fishes used habitats dominated by vegetation, with sand substrates, and that were more stable with regard to environmental conditions. Largemouth bass were more mobile than bluegill sunfish. Fish movements may have been in response to unfavorable environmental conditions, as more mobile fishes were associated with higher water temperatures and lower concentrations of dissolved oxygen.

Abstract/Description
The density and diversity of fishes of the Kissimmee River Floodplain have been affected by channelization of the Kissimmee River. Reduced hydrology, human encroachment, and overall loss of habitat appear to have reduced the level of fish diversity and density within the floodplain of the Kissimmee River. This landmark study collected vegetative habitat and fish population density and diversity data within the altered floodplain for baseline information prior to initiation of river...
Show moreThe density and diversity of fishes of the Kissimmee River Floodplain have been affected by channelization of the Kissimmee River. Reduced hydrology, human encroachment, and overall loss of habitat appear to have reduced the level of fish diversity and density within the floodplain of the Kissimmee River. This landmark study collected vegetative habitat and fish population density and diversity data within the altered floodplain for baseline information prior to initiation of river restoration activities in the form of dechannelization. Secondary studies included poecillid fecundity data as well as a localized rotenone study within the previously restored am of Pool B. Overall results of the study indicate that post restoration floodplain fish collection studies should reveal increased fish density and diversity within the expanded and restored floodplain habitat.

Plant colonization on a newly restored floodplain of the Kissimmee River, Florida
Title
Plant colonization on a newly restored floodplain of the Kissimmee River, Florida.
Creator
Pinneo, Janet R., Florida Atlantic University, Gallagher, Jacqueline
Abstract/Description
This study focused on whether wetland vegetation could become re-established on a newly restored floodplain of the Kissimmee River if seasonal floodplain inundation were re-established. The wetland was re-created by back-filling a section of the Kissimmee Canal and diverting water flow into remnant river meanders. Seasonal flooding did occur during the study period. There were no other interventions to promote wetland plant growth. Ten vegetation quadrats were stratified between the back...

The wetland was re-created by back-filling a section of the Kissimmee Canal and diverting water flow into remnant river meanders. Seasonal flooding did occur during the study period. There were no other interventions to promote wetland plant growth. Ten vegetation quadrats were stratified between the back-filled canal and adjacent floodplain. These quadrats were monitored for 11 months. Of the 68 plant species recorded, 72% were obligate, facultative wetland or aquatic species. Diversity, richness, and percent cover of wetland plants increased with time. Coverage of broadleaf marsh habitat increased with increasing water depths. Vegetation at the end of the study period was similar to pre-channelized estimates. Restoration of hydrologic fluctuations appears sufficient to re-establish wetland habitat in this area of the Kissimmee River basin.

Title
The avian community characteristics of constructed treatment wetlands of South Florida.
Creator
Beck, Tyler J., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
This study compared the avian communities of treatment wetlands in South Florida called Stormwater Treatment Wetlands (STAs) to those in natural marshes and crop lands, and examined factors that influenced the size and structure of the avian communities within the STAs. The STAs contained a more abundant, rich and distinct avian community compared to reference land types. The STAs were dominated by wintering waterfowl, and therefore community patterns fluctuated more seasonally other land...
Show moreThis study compared the avian communities of treatment wetlands in South Florida called Stormwater Treatment Wetlands (STAs) to those in natural marshes and crop lands, and examined factors that influenced the size and structure of the avian communities within the STAs. The STAs contained a more abundant, rich and distinct avian community compared to reference land types. The STAs were dominated by wintering waterfowl, and therefore community patterns fluctuated more seasonally other land types. Within the STAs, density and richness in the fall and winter were much greater in the submerged aquatic vegetation than in the mixed emergent vegetation when waterfowl were present. The STAs maintain two vegetation treatments which enhanced their biodiversity value by supporting distinct avian communities with different migratory strategies This suggests the increase in treatment wetlands could partially offset the loss of natural wetlands, but avian communities in treatment wetlands are not surrogates for natural wetlands.

Markers of Hypoxic Stress in Fishes of the Kissimmee River
Title
Markers of Hypoxic Stress in Fishes of the Kissimmee River.
Creator
Dirk, Lynda J., Milton, Sarah L., Florida Atlantic University
Abstract/Description
The channelized Kissimmee River experiences seasonally low dissolved oxygen levels which have changed the ecosystem to favor air-breathing species, while gamefish populations have declined greatly. In 2001 , the central portion of the river (Pool C) was physically restored. To evaluate the usefulness of various stress markers and assess the success of the partial restoration, the stress responses were analyzed (brain monoamines, heat shock proteins, and plasma cortisol) of air-breathing fish ...

In 2001 , the central portion of the river (Pool C) was physically restored. To evaluate the usefulness of various stress markers and assess the success of the partial restoration, the stress responses were analyzed (brain monoamines, heat shock proteins, and plasma cortisol) of air-breathing fish (bowfin, Florida gar), versus gamefish (largemouth bass and bluegill sunfish). Fish were collected from hypoxic and normoxic water at three sites in the Kissimmee River. Statistical analysis (MANOV A) showed overall significantly higher stress response in hypoxic gamefish than those in normoxia, with higher hsp72 levels, DOPAC, and Dopamine turnover (DOPAC:DA). Hsp60 and cortisol was significantly higher only in hypoxic bass while serotonin and 5-HIAA were significantly higher in hypoxic bluegill sunfish. Air-breathers did not show higher stress levels during hypoxia.
