- Title
- Productivity and Nutrition of Sargassum: A Comparative Ecophysiological Study of Benthic and Pelagic Species in Florida.
- Creator
- Feibel, Alison, Lapointe, Brian E., Florida Atlantic University, Charles E. Schmidt College of Science, Center for Environmental Studies
- Abstract/Description
-
Benthic algal species receive elevated nitrogen (N) and phosphorus (P) availability as anthropogenic activities increase the loading of nutrients into coastal waters. Pelagic species could also be responding to this nutrient enrichment. This study compared the tissue nutrient content and productivity of three benthic and two pelagic species of Sargassum. We hypothesized that the benthic species would have a higher tissue nutrient content and productivity than the pelagic species and the...
Show moreBenthic algal species receive elevated nitrogen (N) and phosphorus (P) availability as anthropogenic activities increase the loading of nutrients into coastal waters. Pelagic species could also be responding to this nutrient enrichment. This study compared the tissue nutrient content and productivity of three benthic and two pelagic species of Sargassum. We hypothesized that the benthic species would have a higher tissue nutrient content and productivity than the pelagic species and the pelagic species would have a higher tissue nutrient content and productivity than historic data. The tissue nutrient content and net productivity of the benthic and pelagic species were not significantly different indicating that the pelagic species are receiving high levels of nutrient availability comparable to that of the benthic species. Pelagic species in the current study exhibited significantly higher N:P ratios and net productivity than the historic data, suggesting a shift from N to P limitation and increased productivity.

- Title
- Butterfly populations in the Florida Big Cypress Swamp: Can they be used as bioindicators?.
- Creator
- DaCosta, Michelle A., Florida Atlantic University, Volin, John C.
- Abstract/Description
-
The need for biological monitoring is increasing in importance as conservation programs are established for natural areas. The primary purpose of this study was to gain basic information on butterfly assemblages that would be useful in developing the use of butterflies as bioindicators. I examined the diversity and seasonal abundance of adult butterflies in seven locations comprising seven habitat types in the Big Cypress Seminole Indian Reservation in southern Florida; two wet meadows, two...
Show moreThe need for biological monitoring is increasing in importance as conservation programs are established for natural areas. The primary purpose of this study was to gain basic information on butterfly assemblages that would be useful in developing the use of butterflies as bioindicators. I examined the diversity and seasonal abundance of adult butterflies in seven locations comprising seven habitat types in the Big Cypress Seminole Indian Reservation in southern Florida; two wet meadows, two pine flatwoods, two ecotones, and a disturbed roadside were studied. One ecotone occurred between a wet meadow and a dry hammock, the other between a pine flatwoods and a wet prairie marsh community. Forty-three butterfly species were found during the one-year study. Several butterfly species were found to be potential indicators in most of the habitats studied. Overall, butterfly diversity did not differ significantly among habitats or between seasons, although seasonal differences in abundance were apparent.

- Title
- The use of nesting initiation dates of roseate spoonbills ( Ajaia ajaja) in northeastern Florida Bay as an ecosystem indicator for water management practices, 1935--1999.
- Creator
- Alvear Rodriguez, Elsa Marcella., Florida Atlantic University, Ogden, John C., Mahoney, Sheila A.
- Abstract/Description
-
Quantity and timing of freshwater flow from the Everglades to Florida Bay varied under different water management practices in the twentieth century, with negative ecological repercussions. Ecological indicators that respond to differences in hydrology, such as wading bird colony dynamics, can be used for hydrological restoration projects. I examined the possibility of using timing of nesting of Roseate Spoonbills (Ajaia ajaja) in northeastern Florida Bay as an ecological indicator. Nest...
Show moreQuantity and timing of freshwater flow from the Everglades to Florida Bay varied under different water management practices in the twentieth century, with negative ecological repercussions. Ecological indicators that respond to differences in hydrology, such as wading bird colony dynamics, can be used for hydrological restoration projects. I examined the possibility of using timing of nesting of Roseate Spoonbills (Ajaia ajaja) in northeastern Florida Bay as an ecological indicator. Nest initiation dates (N = 51) from 1936--1999 (x = November 25) were calculated from numerous published and unpublished sources. The dates were strikingly consistent and did not show significant trends over the entire study period, nor did the dates differ among periods of different water management practices. Early dates were not correlated with favorable hydrologic conditions (low water levels, fast drying rates) in spoonbill foraging habitat. Spoonbill timing of nesting appears to be a poor ecological indicator for Florida Bay.
