Novel disturbances can increase the vulnerability of pine flatwoods to exotic species such as Caesar’s weed (Urena lobata), a plant that has invaded many ecosystems. To understand Caesar’s weed response to disturbance, a factorial field manipulation was used to quantify invasion success.

Show moreNovel disturbances can increase the vulnerability of pine flatwoods to exotic species such as Caesar’s weed (Urena lobata), a plant that has invaded many ecosystems. To understand Caesar’s weed response to disturbance, a factorial field manipulation was used to quantify invasion success. Influence of feral swine (Sus scrofa) on the presence of seeds in the area was analyzed. The effect of heat on Caesar’s weed germination was also quantified. A winter fire and mechanical soil disturbance had no statistical effect on the spread of Caesar’s weed. However, in feral swine disturbed soils Caesar’s weed was more likely to be husked and experience less competition from seeds of other species. Low levels of seed heating increased germination. This data can provide information about the influences of fire and soil disturbances on the spread of Caesar’s weed, as well as how fire intensity levels can affect the spread of invasive Caesar’s weed.

Show moreAs cities grew throughout the past century, the availability of locally grown food declined, mostly because urban expansion occurred at the expense of adjacent agricultural land. As a result, city dwellers turned to commercial food market systems that import food from distant production areas. Private greenspace, which is one of the largest land cover types in cities, offers the potential for substantial agricultural production. Because urban food production on private land, such as backyards, requires the willing participation of landowners, resident's feelings about and experience with food growing are important to understand. The demographic groups that were most likely to food garden were those in long-term relationships, higher income brackets, those with college education and residents over 50 years old. Incentives and programs focused on producing more from existing gardens may be most appropriate for people in these demographic groups, while other groups will most require basic food growing information. Study participants highly valued intangible benefits of food gardening (e.g., relaxation, feelings of happiness and satisfaction), often more than the provision of food. Most barriers and problems with backyard food growing, such as a lack of space and the need for gardening information, were similar for those who food garden and those who do not. Results from this study indicate that traditional agricultural incentives and perspectives must be rethought if they are to be applied in urban settings. By creating incentives and initiatives that reflect the needs and challenges faced by urban growers, urban agriculture will become an integrated part of the community, improving food quantity and quality while enriching residents' lives.

The burden of disease is not limited to mental disorder comorbidities; psychological stress can also induce or exacerbate chronic medical diseases such as obesity, diabetes, and hypertension (Brunner & Marmot, 2006; Sridhar, 2007). ... The continuation of this disregard will add to the health disparity of this nation by delaying assessment, treatment, and development of interventions. The purpose of this study was to explore cumulative trauma as it related to social determinants of health and pathophysiological, psychological, and health behaviors of 102 adult Mayas living in Southeast Florida. The trauma profile for the Mayan population sample obtained through this study reflected high exposure to different types of trauma; collective identity trauma was most frequently reported, followed by survival trauma, achievement trauma, secondary trauma, and personal identity trauma, with high rates of repetition of the same traumas ...

Little is known about nitrogen (N) and phosphorus (P) limitation or the importance of morphological/physiological characteristics of bloom-forming macroalgae (Ulva lactuca, Hypnea musciformis, and Gracilaria tikvahiae) in the IRL. We hypothesized: 1) all species would proliferate in nutrient-rich Titusville, 2) opportunistic U. lactuca would dominate, 3) Rapid Light Curves (RLCs) would assess nutrient status, and 4) nutrient concentrations would regulate growth more than N:P ratios. Field studies showed rapid biomass doubling times of 2 days (U. lactuca; November 2012) in urbanized Titusville. RLCs in a guano-enriched island off Big Pine Key (BPK) and Titusville (Ulva spp.) were similar due to P-saturation. Laboratory studies showed three-fold higher RLCs and two-fold faster growth at high nutrient concentrations of N and P. Reductions of both N and P will be required to moderate future blooms.

Show moreThe recent financial crisis which has beset the United States has made itself felt in a number of ways, not the least of which has been its adverse effect on the housing market. As foreclosure percentages accelerated, increasing numbers of properties across the country became empty and abandoned, leaving a visible imprint of deterioration in neighborhoods that were significantly affected. Initial GIS analysis of both foreclosed and non-foreclosed residential land in Broward County Florida was conducted, showing that there is a discernible spectral difference in the lawn space of these two types of properties, with foreclosed properties exhibiting more brownness, or loss of green space. In order to evaluate whether or not this visible deterioration has had an effect on residents left behind in areas of foreclosure and their own habits, 950 mail-in surveys were distributed throughout 19 different census tracts in Broward County, inquiring about demographics, surrounding foreclosures, degrees of concern for home value and appearance, and changes in lawn maintenance since the foreclosure crisis along with reasons for such change if such exists. Data received from respondents was then analyzed in order to identify any attributes or correlations which might contribute to further neighborhood change, and how any of these factors might be affecting attitudes or perceptions of those left behind, as well as their lawn maintenance habits.

Show moreThis study focuses on two main broad areas of active research on climate: climate variability and climate change and their implications on regional precipitation characteristics. All the analysis is carried out for a climate change-sensitive region, the state of Florida, USA. The focus of the climate variability analysis is to evaluate the influence of individual and coupled phases (cool and warm) of Atlantic multidecadal oscillation (AMO) and El Niäno southern oscillation (ENSO) on regional precipitation characteristics. The two oscillations in cool and warm phases modulate each other which have implications on flood control and water supply in the region. Extreme precipitation indices, temporal distribution of rainfall within extreme storm events, dry and wet spell transitions and antecedent conditions preceding extremes are evaluated. Kernel density estimates using Gaussian kernel for distribution-free comparative analysis and bootstrap sampling-based confidence intervals are used to compare warm and cool phases of different lengths. Depth-duration-frequency (DDF) curves are also developed using generalized extreme value (GEV) distributions characterizing the extremes. ... This study also introduces new approaches to optimally select the predictor variables which help in modeling regional precipitation and further provides a mechanism to select an optimum spatial resolution to downscale the precipitation projections. New methods for correcting the biases in monthly downscaled precipitation projections are proposed, developed and evaluated in this study. The methods include bias corrections in an optimization framework using various objective functions, hybrid methods based on universal function approximation and new variants.

Show moreWorldwide research of bottlenose dolphins (Tursiops truncatus) has led to varied definitions and terminology regarding ways to group dolphins for study and management. An understanding of the demographic history and population structure of bottlenose dolphins residing within the Indian River Lagoon Estuary System (IRLES), Florida, is needed to help define the IRLES dolphin population: ecotype, population, or community. Using mitochondrial DNA sequencing and microsatellite genotyping, this study detected: (1) genetic differentiation between estuarine and coastal individuals (FstmtDNA=0.414, Fstmsat=0.057; p<0.05; K=2), (2) genetic differentiation between the Indian River Lagoon (IRL) and Mosquito Lagoon (ML) (FstmtDNA=0.0201, Fstmsat=0.0234; p<0.09), and (3) minute undefined sub-structure within the IRLES (FstmtDNA=-0.00 -0.0379, Fstmsat=0.00 - vii 0.0445; p>0.1). Additionally, within ML this study detected non-mixing cohabitation of two potential ecotypes, estuarine and coastal. These findings raise many questions regarding how dolphins are presently categorized and managed which are critical to population assessments including abundance, vital rates, and health.

Show moreThis qualitative research study explores the relationship between reducing uncertainty and assigning source credibility in the context of social media sites (SMS) and examines the effect of uncertainty reduction within the social media environment on the development of relationships between journalists and their sources. For this study, interviews were conducted with professional journalists to determine whether uncertainty was reduced and credibility was established with sources via SMS (i.e., Facebook, Twitter, and LinkedIn) and what theoretical strategies journalists used to reduce their uncertainty. The study also aims to determine if correlations exist between a reporter's age, beat, and/or personal adoption of SMS and the reporter's usage of SMS for source development. The interviews were conducted with 15 journalists of The Palm Beach Post (West Palm Beach, Florida), using a standardized interview protocol. Subjects were asked to voluntarily participate in a face-to-face interview with the researcher. Reporters were selected based upon their gender and cultural ethnicity, which was representative of the newsroom demographics of The Palm Beach Post at that time. This research aims to contribute to the uncertainty reduction theory in the realm of computer-mediated communications, specifically with regard to the use of SMS in forming and maintaining journalist-source relationships.

Show moreThis study compared the avian communities of treatment wetlands in South Florida called Stormwater Treatment Wetlands (STAs) to those in natural marshes and crop lands, and examined factors that influenced the size and structure of the avian communities within the STAs. The STAs contained a more abundant, rich and distinct avian community compared to reference land types. The STAs were dominated by wintering waterfowl, and therefore community patterns fluctuated more seasonally other land types. Within the STAs, density and richness in the fall and winter were much greater in the submerged aquatic vegetation than in the mixed emergent vegetation when waterfowl were present. The STAs maintain two vegetation treatments which enhanced their biodiversity value by supporting distinct avian communities with different migratory strategies This suggests the increase in treatment wetlands could partially offset the loss of natural wetlands, but avian communities in treatment wetlands are not surrogates for natural wetlands.

This study also sought to determine if this relationship was moderated by each school's level, size, letter grade, socioeconomic status (FRL), gender of principal, as well as gender and race of the presiding district superintendent. Lastly, the relationship between each moderator variable and the placement of African American principals was examined. The ultimate objective was to determine if limited opportunities still widely exist in the placement of African American principals throughout Florida. ... From a legal perspective, although Brown and its progeny of civil rights laws valiantly set out to eliminate race and racism from schools and in the workplace, the findings revealed that race continues to be a factor in determining inequity in principal placements.

Show moreThe face of North America's public education system is changing. Across the United States, hundreds of thousands of students have migrated away from traditional public school into charter schools. While both are considered public schools, often that is where the similarity ends. Claims and counter claims have been made about the virtues and advantages of a charter school versus the traditional public school. This study, focused on the nation's sixth-largest school system in Broward County, Florida, compares comments from stakeholders involved in charter programs to feedback from those still involved in the traditional public system. Three hypotheses are evaluated including: whether traditional schools are not adequately serving the needs of students; whether charter schools are better at serving student needs; or people believe that charter schools are doing a better job at serving the needs of students. Evidence suggests that while each model of education has its advantages and disadvantages, neither clearly provides a ""better" opportunity for students. Conclusions are that consumer perceptions are driving the shift in enrollment. This is attributed to the narrative about "choice" created by charter school advocates that aligns with American ideologies of liberty, freedom and independence. Ultimately, it is argued that the deconstruction of the traditional public education system is part of a larger effort to shift selected rights and privileges out of the public sphere and back into private control. For traditional public schools to regain momentum, they must learn to control the narrative and ultimately public policy and public opinion about our nation's public schools.

Nevertheless, the effects of environmental variation and habitat structure on animal population success in wetlands are important for understanding both trophic interactions and biodiversity. I performed two experiments to determine the factors limiting crayfish (Procambarus fallax) and dragonfly (Family: Libellulidae) populations in wetland environments. A simulation of a dry-disturbance and subsequent sunfish (Family: Centrarchidae) re-colonization revealed that crayfish populations are sensitive to sunfish, while dragonfly naiads seemed to be limited by other drying-related factors. A second manipulation revealed that small-bodied fishes and habitat structure (submerged vegetation) shaped dragonfly communities primarily through postcolonization processes.

Nest temperatures and SRs differed between leatherbacks and loggerhead and green turtles. The latter two did not differ. The loggerhead response parameters were estimated within biological limitations by both 50-65% of incubation and mean middle 1/3 temperature. The maximum middle 1/3 temperature was the best-fit predictor for green turtles. No best-fit sex ratio-temperature response could be identified for leatherbacks. Clutches incubating under natural conditions can vary greatly in SR ; TRT differences may account for differences among species' sex ratios.

Show moreThis study created an ecological spatial model, using a geographic information system, to visualize the influence of hydrochory on restoration of the three dominant wetland communities of broadleaf marsh, wetland shrub, and wet prairie across the floodplain of the Kissimmee River. Primary parameters incorporated into the model included floodplain hydrology, seed characteristics of buoyancy and dispersal rates, and species flood tolerance. S²rensen's similarity index, comparing spatial agreement among model output and observed community data, resulted in values of BLM-BB = 0.10, BLM = 0.07, WS = 0.21, and WP = 0.36. The significant discrepancies between modeled and observed community spatial coverage indicated a need for incorporation of more stochastic variables of climatic disturbances, nutrient availability, and soil characteristics. More research on species flood tolerance across smaller spatial scales is also needed, and base data incorporated into the model should also be reliable and consistent if accuracy is to be achieved.

The construction of Abacoa included an attempt to conserve the wildlife in a Greenway, a set of habitats separated from the residential and commercial areas. All of the wetlandswith in Abacoa represent artificially constructed ponds, canals, and streams first created from 1998-2004. The present study focuses on the anuran (i.e., frog and toad) populations and looks at the number of different species that have naturally colonized six differnet sites around Abacoa.

Show moreThe construction of Abacoa included an attempt to conserve the wildlife in a Greenway, a set of habitats separated from the residential and commercial areas. All of the wetlandswith in Abacoa represent artificially constructed ponds, canals, and streams first created from 1998-2004. The present study focuses on the anuran (i.e., frog and toad) populations and looks at the number of different species that have naturally colonized six differnet sites around Abacoa. Each of these sites varies in qualities that may affect the probability of breeding in that section. The quality of water is known to be less ideal as the water flows away from the headwaters and mixes with water from other sources. This study aims to determine which anuran species are found at each of these sites after nearly a decade of colonization, and how both anuran diversity and abundance correlates with water and habitat quality.

This study assesses the philosophical underpinnings of endangered species protections focused on gopher tortoises in Florida. From 1993-2007, gopher tortoises (Gopherus polyphemus) were listed in Florida as a species of special concern. Land developers wanting to build on their habitats could apply for an incidental take permit, paying a fee that allowed tortoises to be 'entombed' in their burrows to die a slow death. In 2007, when gopher tortoise status was up-losted to 'threatened', a new...
Show moreThis study assesses the philosophical underpinnings of endangered species protections focused on gopher tortoises in Florida. From 1993-2007, gopher tortoises (Gopherus polyphemus) were listed in Florida as a species of special concern. Land developers wanting to build on their habitats could apply for an incidental take permit, paying a fee that allowed tortoises to be 'entombed' in their burrows to die a slow death. In 2007, when gopher tortoise status was up-losted to 'threatened', a new policy ended the incidental take permit program. This study compares policy guidelines of the 1991 and 2007 gopher tortoise management plans and explores cases that deal with incidental take controversies. I will apply perspectives from environmental philosophy to my analysis to understand how policies attempt to balance economic goals with a mandate to protect species in peril.
