- Assessment of a nearshore and an offshore queen conch (Strombus gigas) habitat in the Florida Keys using field and laboratory techniques.
- Creator

- Abstract/Description
-
Queen conch in the Florida Keys are slowly recovering from overfishing. This study assessed habitat characteristics, metamorphosis and postlarval growth of queen conch in a nearshore and an offshore habitat. The nearshore habitat was dominated by macroalgae while the offshore habitat was dominated by areas of open coarse sediment and seagrass. There was a significant difference among the top six diatom families at each habitat (p 0.05). Larvae metamorphosed when exposed to sediment from...
Show moreQueen conch in the Florida Keys are slowly recovering from overfishing. This study assessed habitat characteristics, metamorphosis and postlarval growth of queen conch in a nearshore and an offshore habitat. The nearshore habitat was dominated by macroalgae while the offshore habitat was dominated by areas of open coarse sediment and seagrass. There was a significant difference among the top six diatom families at each habitat (p < 0.001). The diatom family Naviculaceae was dominant at both sites. No difference in microbial populations was observed (p>0.05). Larvae metamorphosed when exposed to sediment from nearshore and offshore locations (10-40%). Larvae exposed to offshore sediment at 27°C exhibited the highest metamorphic response (~40%). There was no significant difference in growth rate of post larvae fed the food present in the sediment from nearshore and offshore locations. This study may help explain aggregation differences between a nearshore and an offshore queen conch habitat.

- Population distribution, habitat selection, and life history of the slough crayfish (Procambarus fallax) in the ridge-slough landscape of the central Everglades.
- Creator
- Van der Heiden, Craig., Charles E. Schmidt College of Science, Department of Biological Sciences
- Abstract/Description

Understanding where and why organisms are distributed in the environment are central themes in ecology. Animals live in environments in which they are subject to competing demands, such as the need to forage, to find mates, to reproduce, and to avoid predation. Optimal habitats for these various activities are usually distributed heterogeneously in the landscape and may vary both spatially and temporally, causing animals to adjust their locations in space and time to balance these conflicting...
Show moreUnderstanding where and why organisms are distributed in the environment are central themes in ecology. Animals live in environments in which they are subject to competing demands, such as the need to forage, to find mates, to reproduce, and to avoid predation. Optimal habitats for these various activities are usually distributed heterogeneously in the landscape and may vary both spatially and temporally, causing animals to adjust their locations in space and time to balance these conflicting demands. In this dissertation, I outline three studies of Procambarus fallax in the ridge-slough landscape of Water conservation Area 3A (WCS-3A). The first section outlines an observational sampling study of crayfish population distribution in a four hectare plot, where I statistically model the density distribution at two spatial scales. ... Secondly, I use radio telemetry to study individual adult crayfish movements at two study sites and evaluate habitat selection using Resource Selection Functions. In the third section, I test the habitat selection theory, ideal free distribution, by assessing performance measures (growth and mortality) of crayfish in the two major vegetation types in a late wet season (November 2007) and early wet season (August 2009).

- Evaluation of fish populations and relative abundance within Pools A, B and C of the Kissimmee River: Possible responses to the Pool B demonstration project.
- Creator
- Miller, Daniel E., Florida Atlantic University, Courtenay, Walter R. Jr.
- Abstract/Description
-
Channelization of the Kissimmee River from 1962 to 1971 altered the natural hydrology of the river/floodplain system. Results of construction of the C-38 canal included loss of continuous flow of water and loss of floodplain habitat which adversely impacted the fish community. In 1984 the South Florida Water Management District (SFWMD) constructed the Pool B demonstration project to evaluate the feasibility of a planned restoration project.

Show moreChannelization of the Kissimmee River from 1962 to 1971 altered the natural hydrology of the river/floodplain system. Results of construction of the C-38 canal included loss of continuous flow of water and loss of floodplain habitat which adversely impacted the fish community. In 1984 the South Florida Water Management District (SFWMD) constructed the Pool B demonstration project to evaluate the feasibility of a planned restoration project. To evaluate success of the demonstration project in enhancing the Pool B fish fauna, a hoop net sampling program was conducted in 1996. The data suggest that black crappie (Pomoxis nigromaculatus) and other sport species in Pool B are benefiting from habitat enhancements resulting from the demonstration project. Additional analysis distinguishes black crappie as the only centrarchid sampled that maintains activity during nocturnal hours. Bluegill (Lepomis macrochirus) were most active during May sampling when water temperatures were optimal for spawning.
