- The Effect of Sea Level Rise on Juncus roemerianus’s Ability To Remain An Environmental Restoration Indicator Species.
- Creator
- Abbott, Cara J., Berry, Leonard, Graduate College
- Abstract/Description
-
Juncus roemerianus, the black rush, has long been used in restoration projects in south Florida because of its unique ability to live in both freshwater and saltwater. In particular, it has been used as an indicator of salt-water incursion due to its differing physical forms in varying levels of salinity. When found in freshwater, it can reach heights over 2.1 meters, yet when found in hypersaline water, it becomes dwarfed and only 1 meter in height. Because of its dramatic differences in...
Show moreJuncus roemerianus, the black rush, has long been used in restoration projects in south Florida because of its unique ability to live in both freshwater and saltwater. In particular, it has been used as an indicator of salt-water incursion due to its differing physical forms in varying levels of salinity. When found in freshwater, it can reach heights over 2.1 meters, yet when found in hypersaline water, it becomes dwarfed and only 1 meter in height. Because of its dramatic differences in physical appearance due to salinity, it has provided an easy and fairly cheap method of determining an area’s localized salinity level. Most of Juncus roemerianus’s range in Florida lies around the coasts, which most models predict will experience significant changes due to sea level rise in the not so distant future. The purpose of this study is to determine whether the black rush can remain an environmental restoration indicator species in conditions influenced by sea level rise. This study will take place in the FAU Boca greenhouse and will target increased water levels and increased pH as the main conditions affected by sea level rise. If this study finds that increased water levels and pH do not significantly change the appearance of Juncus roemerianus in varying salinity, then this plant can confidently remain an indicator of salt-water incursion in the future. Conversely, if these conditions do change the appearance of Juncus roemerianus, then this plant may not remain an indicator species in South Florida in the future.

- Abstract/Description
-
Road networks have significant impacts on ecosystems through deforestation, rapid land conversion and wildlife-vehicle collisions. Road ecology seeks to analyze the spatial and biological patterns of collisions to understand the effect of roadways and best inform transportation planning in mitigating these threats. 215 km of roadway BR-262, that bisects critical habitat of the Brazilian Cerrado and Pantanal in southwest Brazil, was analyzed between April 2011 and June 2012 to assess how...
Show moreRoad networks have significant impacts on ecosystems through deforestation, rapid land conversion and wildlife-vehicle collisions. Road ecology seeks to analyze the spatial and biological patterns of collisions to understand the effect of roadways and best inform transportation planning in mitigating these threats. 215 km of roadway BR-262, that bisects critical habitat of the Brazilian Cerrado and Pantanal in southwest Brazil, was analyzed between April 2011 and June 2012 to assess how biological, physical and landscape characteristics affect clustering of collisions. 518 collisions, representing 40 species, were found to be seasonally clustered between the unimodal rain and flood pulse in a February-March-April window and were spatially clustered over the study area in relation to cash crop and cattle ranching land-use and the rural low-lying Pantanal floodplain. Mitigation seeks to work with local communities and transportation agencies to facilitate fauna safe crossing through the roadway that do not conflict with drivers.

As sea levels continue to rise, the projected damage that will ensue presents a great challenge for conservation and management of coastal ecosystems in Florida.

Show moreAs sea levels continue to rise, the projected damage that will ensue presents a great challenge for conservation and management of coastal ecosystems in Florida. Since Juncus roemerianus is a common marsh plant throughout Florida with unique growing characteristics that make it a popular restoration plant, this study implemented a 20 week greenhouse split plot experiment to examine the effects of sea level rise on J. roemerianus and ultimately determine its tolerance ranges to salinity and inundation in a high nutrient environment. Overall, salinity level and the interaction effect of salinity level and water level had the greatest effects on measured growth parameters including average mature height, maximum height, density, basal area, root length, and biomass. An inverse relationship between increasing salinity and the measured growth variables was observed with the greatest growth and survivability in 0 ppt water, survivability and reduced growth in 20 ppt water, survivability and little growth in 30 ppt water, and nearly complete senesce in 40 ppt water. This was the first laboratory study to determine the effect of 40 ppt water on J. roemerianus. Elevated water levels resulted in higher growth variables in the 20 ppt, 30 ppt, and 40 ppt treatments while inundated water levels produced higher growth variables in the 0 ppt treatment despite previous research finding inundation to have completely adverse effects on J. roemerianus. It is likely that the high nutrient environment provided for this study is the cause for this anomaly. The results of this study have major implications for the future of coastal ecosystems that are dominated by stands of J. roemerianus in South Florida and can be used in conjunction with studies on bordering marsh plants to predict shifts in the ecosystems of Florida that are responding to sea level rise scenarios.
