Title: Ecological characterization of a disturbed hardwood forest.
Creator: Dehring, Faith Jennifer., Florida Atlantic University, Austin, Daniel F.
Abstract/Description: The oak hammock within the Flamingo Road ESL in Broward County, Florida has been disturbed by a number of factors. Twenty-one permanent plots were established to characterize the vegetation of the site and to determine the impact of non-natives on diversity and stability of the hammock. Non-native species may reduce species diversity and stability of communities. Point quarter sampling was compared to quadrat sampling. High percentages of non-native species in hammock sampling plots reduced...
Show moreThe oak hammock within the Flamingo Road ESL in Broward County, Florida has been disturbed by a number of factors. Twenty-one permanent plots were established to characterize the vegetation of the site and to determine the impact of non-natives on diversity and stability of the hammock. Non-native species may reduce species diversity and stability of communities. Point quarter sampling was compared to quadrat sampling. High percentages of non-native species in hammock sampling plots reduced Sorensen index of community similarity values below the 50% minimum used to define intact communities. Hammock plots were placed in the same clade as non-native plots by average linkage cluster analysis. Additional analysis separated the hammock plots from the non-native plots. The percent of non-natives (individuals and species) did not reduce diversity in the hammock. The hammock remains intact despite disturbances and invasions by non-natives.

Show morePopulations of Guzmania monostachia, Catopsis berteroniana, C. floribunda and C. nutans were studied in the Fakahatchee Strand State Preserve, located in southwestern Florida in Collier County. The habitat preference, within habitat distributions and quantitative estimates of rarity were determined for each of the bromeliads. Catopsis and Guzmania are found primarily in swamp communities, especially in Fraxinus caroliniana-Annona glabra sloughs. Fraxinus carolihiana is the most comroon host for these bromeliads. On a host, these species are distributed along a vertical gradient probably in relationship to light intensities. Guzmania monostachia is found at the lowest height (Y = 2.5 +- 0.5 m) while Catopsis berteroniana is found at the greatest height (Y = 5.2 +- 0.2 m). Catopsis berteroniana occurs in the lowest densities and Guzmania in the highest. Specific ecological requirements, habitat destruction and the existence at the extremes of their ranges are responsible for the rarity of Catopsis and Guzmania in Florida.

Title: Distribution and species composition of tree islands in Martin and Palm Beach Counties.
Creator: Cox, Anne Cheney., Florida Atlantic University, Austin, Daniel F.
Abstract/Description: Sixty-two coastal and inland tree islands (hammocks) in Martin and Palm Beach Counties were mapped. Species composition was determined for 36 sites and used to test several hypotheses. The hypothesis was tested and supported that the percentage of tropical species inhabiting a tree island increases on north to south and west to east gradients. A linear regression was run to determine patterns in percent composition of tropical species and whether low hammocks were separable from high hammocks...
Show moreSixty-two coastal and inland tree islands (hammocks) in Martin and Palm Beach Counties were mapped. Species composition was determined for 36 sites and used to test several hypotheses. The hypothesis was tested and supported that the percentage of tropical species inhabiting a tree island increases on north to south and west to east gradients. A linear regression was run to determine patterns in percent composition of tropical species and whether low hammocks were separable from high hammocks. Data suggested that a range from 70 to 80 percent tropical species composition might be used to define "tropical" hammocks. Since hammocks in southern Florida are considered habitat islands, the MacArthur and Wilson concept was tested. An obtained slope (z value) of 0.18 compares well with the slope of 0.17 predicted by the MacArthur and Wilson model. A cluster analysis showed similarities of 36 sites based on 83 tree and shrub species present.

Abstract/Description: The invasive exotic wetland tree, Melaleuca quinquenervia, continues to rapidly expand throughout seasonally wet areas of southern Florida. Water managers are concerned that lowering the water levels of Lake Okeechobee, part of the Everglades ecosystem, while benefitting various natural resources, would stimulate the Melaleuca population.

Show moreThe invasive exotic wetland tree, Melaleuca quinquenervia, continues to rapidly expand throughout seasonally wet areas of southern Florida. Water managers are concerned that lowering the water levels of Lake Okeechobee, part of the Everglades ecosystem, while benefitting various natural resources, would stimulate the Melaleuca population. Saplings and seven-week old seedlings were subjected to various hydroperiod treatments, based on a simulation of historical water level variations. Saplings grew taller, increased shoot number, and increased root biomass under longer hydroperiods with fluctuating water levels, including short periods of submersion. Age affected seedling response--those submersed at seven weeks grew slower and had less biomass than submersed 12-week old seedlings, yet mortality was low at both ages. While Melaleuca's plasticity allows it to adapt to hypoxic, aquatic conditions by means of aquatic heterophylly and adventitious roots, like other wetland trees, Melaleuca has limited flood tolerance. Algae and drought also increase mortality.

Show moreSeveral characteristics of butterfly communities were evaluated in seven pine flatwoods units that differed in time since the last prescribed burn (time-since-burn). Abundance, species richness and species diversity of common butterflies were dependent on plant diversity. These butterfly community characteristics and plant species diversity declined with time-since-burn. Atrytonopsis Manna loammii , a rare butterfly, was found during three different flight seasons in a unit that had been burned in July 1997, as well as a unit burned in February 1999, indicating that early recovery of recently burned units can provided suitable habitat for this rare species. Proper burn rotations and invertebrate surveys are recommended for the conservation of rare species.

Title: The effects of cypress dome size on epiphyte diversity in southern Florida.
Creator: Muss, Jordan, Florida Atlantic University, Austin, Daniel F.
Abstract/Description: Epiphyte richness and abundance were observed in 18 cypress domes spanning two regions in South Florida that were classified by annual low temperature differences of 4.05°C. Using the Preston model of island biogeography and linear regression, the following hypotheses were tested: (1) Larger domes have greater epiphyte diversity because they moderate temperature extremes better than smaller domes. (2) The effect of cypress dome size is reduced in subtropical compared to more temperate regions...
Show moreEpiphyte richness and abundance were observed in 18 cypress domes spanning two regions in South Florida that were classified by annual low temperature differences of 4.05°C. Using the Preston model of island biogeography and linear regression, the following hypotheses were tested: (1) Larger domes have greater epiphyte diversity because they moderate temperature extremes better than smaller domes. (2) The effect of cypress dome size is reduced in subtropical compared to more temperate regions. (3) A measurable temperature gradient exists within cypress domes. The analyses indicated that epiphyte distribution in cypress domes fits the Preston model. In addition to an increase in diversity with area, there were regional differences that were correlated to temperature, however, these differences diminished as dome size increased. Within the domes, an increase in diversity was correlated to significant differences between dome edge and center temperatures, indicating the occurrence of factors that were influenced by area.

The dominance values of trees and shrub were used in cluster analysis to delineate plant communities. Qualitative data on logging and fire history was obtained by inspecting aerial photographs and surveillance in the field. Local water regime, as a function of topography, appears to be the most important factor associated with the distribution of plant communities in Fakahatchee Strand. Logging of cypress and subsequent dominance of hardwoods has altered the species composition of most communities so that community types have become more distinct from one another. The species composition of plant communities has apparently been altered even more when severe fire followed logging.

Show moreEnvironmental parameters were quantified to develop a physiognomically-based system for describing and predicting gopher tortoise (Gopherus polyphemus) habitat on the Florida Atlantic University Nature Preserve. There were significant correlations among gopher tortoise densities and all physiognomic features except saw palmettos. The only feature with predictive usefulness was bare ground as indicated by a multiple regression. Burrows were regularly dispersed and the highest densities occurred in wet prairie associations. Tortoises located burrows in areas with less canopy and shrub cover but greater herbaceous cover and more extensive bare ground. This physiognomically-based system for predicting location of gopher tortoise habitats should prove useful in the relocation of displaced tortoises as required by the Florida Game and Fresh Water Fish Commission.

Median short shoot age was approximately two years. No evidence of sexual reproductive effort was found. A site-specific leaf emergence rate was not used, which may have contributed error in the reconstructive technique. Gradients in salinity, phosphorous availability, community composition, and leaf width were observed along the water flow pathway through the ponds. Populations of short shoots more distal from the tidal source exhibited an older age structure reflecting higher salinity, temperature, and dissolved oxygen stresses. Populations closest to apparent sources of nutrient enrichment were skewed toward young individuals. A significant positive relationship between increasing short shoot mortality and recruitment was identified. A significant correlation between low phosphorous availability and narrow leaf width was observed, and a positive relationship between phosphorous availability and recruitment was suggested.

These areas are permitted through the South Florida Water Management District's Management and Storage of Surface Waters or Environmental Resource Permit Process. WRAP evaluation is designed for the limited timeframes of the regulatory process. The objectives of WRAP are: (1) to establish an accurate, consistent, and timely regulatory tool; (2) to track changes in wetland sites over time (i.e., baseline data); and (3) to offer guidance for environmental site plan development. Test results of the WRAP procedure showed it to be a repeatable and effective training tool for biologists. Although some general trends were observed regarding land use and variable scores, additional data will need to be collected to establish more conclusive relationships between land use and wetland function.

Harper], in the Fakahatchee Strand State Preserve. Associated species, seedling establishment and germination, growth rates, size class ratios and elevation of establishment (epiphytic nature) were examined. The palm showed a preference for high ground as indicated by the increasing colonization of elevated logging tramways. Seeds germinated under low light conditions in 17-22 days. Seedlings had an escalating growth rate from 4.2 em/year for seedlings to approximately 50 em/year for adults. Each size class was well represented in the Fakahatchee Strand, suggesting that reproduction was not being hindered by changes in water level, cold and area urbanization. Elevation of seedling establishment was a function of water level during that particular year and did not correlate year to year. These data indicate a stabilization of the Royal Palm population in the Fakahatchee Strand.

Vegetative community composition and structure were examined in detail in twenty-one study plots located throughout the study site. Successional assemblages are described qualitatively and quantitatively. Distinct community types are defined using methods that emphasize site-to-site comparisons. The relationship between vegetation and substrate, farming history, hydroperiod, and spatial arrangement was examined. Results were used to summarize and predict trends of old field succession on abandoned farmland in southern Florida. Post-farming vegetation patterns do not resemble prefarming conditions. Successional forest, frequently dominated by exotic species, is a relatively new community in southern Florida. It is likely a final stage in secondary succession on abandoned farmland.

Comparative data came from 28 outgroup species in 15 families and six ingroup species. Phylogenetic Analysis with PAUP 3.1 produced twelve equally parsimonious trees; these were used to generate a strict consensus tree. MacClade 3.06 was used to refine the polytomies in the consensus tree. Analysis indicates that the Cactaceae is a monophyletic clade; moreover, these results support the work of other analyses that the sister family to Cactaceae is the Portulacaceae. Other relationships within the order are not completely consistent with previous studies. For example Molluginaceae and Caryophyllaceae occupy a central position in the cladogram; Achatocarpaceae aligns with the Amaranthaceae and Chenopodiaceae; and Basellaceae is presented as the basal family within the order. Lastly, the Jamaican cactus Opuntia spinosissima was derived from a common ancestor with the Florida Keys endemic, Opuntia corallicola.
