The primary objective was to use these models to determine which life cycle stages and demographic processes contribute most to population success or demise. The outcome of the research was reported to both applied conservation and basic science audiences in the form of an oral presentation (2010 FNPS meetings in Tallahassee, and Annual Meeting of Ecological Society of America) and papers published in professional journals
- Evaluation and conservation of Harperocallis flava, a federally endangered plant in the savannas of the Apalachicola River Basin.
Herbert Kesler and Jennifer Trusty
(Folius Consulting, 2009)
The objectives of this project were:
- Determine the current status of populations in the ANF
- Estimate the fire frequency and season that maximizes population growth rates for this species Identify which stage in the plants life cycle management can target to ensure the persistence and success of populations.
- Based on these analyses, outline focus for management practices.
This project directly addressed actions outlined in the USFWS Recovery Plan of this species. It was designed to measure the decline or growth of selected populations and their response to fire aiding in the conservation of this species.
- Systematics, biogeography, and conservation genetics of two Florida endemics, Nolina brittoniana and N. atopocarpa (Ruscaceae)
James M. Heaney
(University of Florida and Florida Museum of Natural History – Department of Biology, 2009)
This project was a phylogenetic study of Nolina, based on molecular and anatomical evidence from various localities in Florida. Additional objectives were to quantify patterns of genetic diversity in and among populations and to compare these measures among congeneric species.
- Mating system biology of the Florida native plant: Illicium parviflorum
(University of Tennessee – Department of Ecology and Evolutionary Biology, 2009)
Investigated the mating system and pollination biology of the early diverging angiosperm Illicium parviflorum, a close relative to I. floridanum. Prior to this research, there was no pollination biology known on this species. Illicium parviflorum is endemic to Florida and Georgia; however, the populations in Georgia are thought to have gone extinct (NatureServe 2009). Understanding the mating system biology is essential in determining future conservation strategies. This information will be used in expanding the current knowledge of early diverging angiosperm mating systems.

- Floral biology and molecular phylogenetics of the genus Asimina (Annonaceae)
Katherine R. Goodrich
(University of South Carolina, 2005)
The study investigated several the phylogeny and patterns in floral morphology in the genus Asimina, specifically seeking answers to the following questions:
- What are the basal and derived traits within the genus Asimina and how do they differ from tropical relatives?
- How has Asimina spread geographically into its current range in North America ?
- Do the two floral phenotypes represent an early divergence event, or “suites” of traits which have been gained or lost multiple times?
- What trends in pollinator attraction can be inferred from floral trait evolution within Asimina?
- Is the exotic Brazilian pepper Schinus terebinthifolius a threat to mangrove ecosystems in Florida ?
The purpose of this study was to determine if and how Schinus terebinthifolius out-competes or inhibits growth of the red, black and white mangroves. In Mosquito Lagoon, this was accomplished by determining the ability of Schinus terebinthifolius to:
- chemically inhibit growth of mangrove propagules,
- invade coastal habitats by dispersing seeds in water,
- tolerate conditions within the mangrove canopy, and
- alter species richness and abundance of the flora when present in a mangrove system.
By better understanding the invasibility and impact of Schinus terebinthifolius on mangroves, coastal resource managers will be able to develop the most effective management strategies to prevent this exotic from altering the structure and productivity of the mangrove ecosystem.
- Morphological and Molecular Systematics of the Tillandsia fasciculata (Bromeliaceae) Complex: Biogeographical and Evolutionary Implications
Brian J. Sidoti
(Florida International University - Department of Biological Sciences, 2004)
The purpose of this project was to gain greater insight into the speciation and radiation of species within the Tillandsia fasciculata (Bromeliaceae) complex that occurs in Florida and Cuba . Specifically, anatomical, morphological, and molecular studies were used to examine the T. fasciculata complex in order to support taxonomic decisions and species boundaries. This baseline data was to be used to construct and solidify conservation measures.
- Demography and Phenology of the Endangered Fern, Ophioglossum palmatum, at the Tosohatchee State Preserve
Eliane Norman and Sandra Carnival
(Stetson University (Eliane Norman) and Tosohatchee State Preserve (Sandra Carnival), 2004)
This study evaluated the growth patterns of hand ferns on the Tosohatchee State Preserve. Plants were selected randomly from different sites. Each plant as well as each leaf was tagged. The following parameters were measured or observed 4 times a year: length of stipe; length and width of blade; # of lobes; # of fertile spikes; size of fertile spike and stage of maturation; % of damaged leaves. The data obtained were used to assess of the longevity of the Hand Fern and to relate phenological patterns in leaf growth and spike production and maturation to sesonal variation at the Tosohatchee State Preserve.
- Evaluation and Conservation of a Threatened Carnivorous Plant (Godfrey’s Butterwort, Pinguicula ionantha)
Herbert 'Tug' Kesler
(Auburn University - Dept. Biological Sciences, 2004)
Pinguicula ionantha R. K. Godfrey (Lentibulariaceae) is a recently described species endemic to a 25-mile radius in the panhandle of Florida . Due to its shrinking population size, P. ionantha was listed as threatened by the United States Fish and Wildlife Service on July 12, 1993 and is currently listed as Florida State endangered. This study conducted field and laboratory experiments to gain information needed to conserve federally threatened P. ionantha populations in the panhandle of Florida . The results of both types of research were integrated to create a better understanding of 1) the current status of all 62 known populations, 2) how the survival and fecundity of wild P. ionantha populations are directly effected by prescribed fire, and 3) whether a soil seed bank exists for this species. The goal of the project was to develop recommendations for conservation and management practices that will ensure the long-term survival of federally threatened and Florida endangered, Pinguicula ionantha populations.
- Trophic cascades: influences of herbivory and predation influence on post-fire succession
(University of Florida - Department of Zoology, 2004)
The direct effects of prescribed fire on plant communities have been extensively studied yet little is known about the effects of fire on other trophic levels and trophic interactions. Interspecific interactions, such as herbivory and predation, play important roles in maintaining ecosystem function, however very little is known about their roles in post-fire succession. Predators may indirectly benefit plant communities by alleviating intense herbivory pressures typically associated with post-fire habitats. If predator, top-down controls are strongly felt by plant communities, then herbivory and predation play extremely important roles in post-fire succession. The goal of this research project was to determine whether insect herbivores and vertebrate predators play significant roles in influencing plant growth and reproduction following fire in longleaf pine sandhills. This was accomplished by setting up insect herbivore and vertebrate predator exclosures in longleaf pine sandhill habitats throughout two reserves in north-central Florida .
- The Illicium parviflorum Michx. ex Vent. (Illiciaceae) paradox: an endangered Florida endemic and its role in the horticultural trade
Ashley B. Morris withPamela S. Soltis
(University of Florida (Morris) and Florida Museum of Natural History (Soltis), 2003)
The goal of this study was to assess levels of genetic diversity in natural populations of Florida anise, I. parviflorum, as well as that of horticultural stocks.
This rare species is quite popular in the horticultural trade, and is commonly sold as far north as North Carolina and as far west as Arkansas. It is common practice in plant nurseries to increase their inventories by propagating cuttings, resulting in a genetically homogeneous stock. In addition, many nurseries obtain their original cuttings from the same source, resulting in homogeneity among nurseries. Such practices may have serious consequences for natural populations exhibiting self-incompatibility.
- The genetics of gender flexibility in passionflower
(Stetson University, 2003)
To test ideas related to the evolution of andromonoecy in passionflower, the investigator proposed an experiment toexamine the response of gender expression to resource limitation (imposed through herbivory). Three main questions were addressed:
- Is fruit production limited by the number of cosexual flowers produced by a plant?
- Is there genetic differentiation among populations in the proportion of male flowers per plant?
- Is there genetic differentiation among populations in the degree to which floral gender is influenced by the environment? Genetic differences among populations may be fixed or plastic.
- Effects of invasive exotic trees On the seedling demography of the endangered bromeliad Catopsis berteroniana
Philip A. Gonsiska
(Florida International University, 2003)
South Florida is subject to invasion by exotic species, such as Australian pine (Casuarina spp.), Brazilian pepper (Schinus terebinthifolius), and melaleuca (Melaleuca quinquenervia). These species have the capacity to invade habitats, such as mangrove and buttonwood communities where C. berteroniana is found. Since Australian pine, Brazilian pepper, and melaleuca have the capacity to exclude native vegetation in the habitats they invade, if they are less suitable epiphyte hosts than native tree species, the possibility exists for the decimation of Florida's epiphyte communities. This could result in the extirpation of endangered epiphytes, such as Catopsis berteroniana.
The purpose of the observational portion of this project was to determine the fate of C. berteroniana seedlings during their first year of life on their naturally occurring native host species. The experimental portion of this study determined the effects of host species on seedling recruitment and thereby demonstrated potential effects of invasive woody species on bromeliad communities in south Florida.
