With the first of the 77 million (www.census.gov) Baby Boomers turning 60 this year, the impact on retirement and retirement communities has suddenly become a vital and pressing issue. The massive numbers of Baby Boomer cohorts have amplified and intensified the importance of whatever experiences they've had at each new moment in their lives. When they reach any stage of life, the issues that concern them — whether financial, interpersonal, or even hormonal — become the dominant social political, and marketplace themes at the time. (www.agewave.com 2006) Retirement will be no different. Using this understanding of the Baby Boomer generation, this study examined their impact on retirement community design.Data specific to Baby Boomer retirement preferences was analyzed, an expert in the field of gerontology at Ball State University was interviewed, research was completed in retirement community design and age related health concerns, and case studies in a range of established retirement communities in southwest Florida were visited, all in an effort to determine what the current trends are in the retirement community market today and how Boomers would effect them.Research showed that Boomers want to pursue new and exciting experiences in their retirement years. They are not willing to settle for a retirement tucked out of the way, out of sight out of mind. They want to be in the middle of activity and enjoyment. They are looking to make a difference and have an impact in this next phase of life.The result of these endeavors is a conceptual design for an active adult retirement community, in northeast Lee County Florida, that will attract Baby Boomers by appealing to their sense of fun, their sense of purpose and their social and environmental conscience. / Department of Landscape Architecture

Para tanto, foram realizados estudos com diferentes métodos de extração, estudo de variação metabólica da planta, desenvolvimento e validação de metodologias analíticas, ensaios citotóxicos e ensaios em células tumorais. Os dados obtidos no trabalho apontaram a percolação no tempo de 2 horas como o método que apresentou o melhor percentual de extração de ácido betulínico a partir das folhas de E. florida. Apesar de saber que a granulometria influencia diretamente na eficiência da extração, não foram observadas grandes diferenças percentuais nos teores de ácido betulínico para os diferentes tamanhos de partículas utilizados na extração por ultrassom, porém constatou-se que a homogeneidade dos tamanhos de partículas aumenta a eficiência da extração. No estudo de variação metabólica observaramse variações durante o ano que devem ser consideradas na qualidade da matéria-prima vegetal. Os extratos de E. florida apresentaram baixa citotoxidez em células VERO e apresentaram índice de seletividade alto o que representa uma maior afinidade pelas células tumorais do que pelas células sadias (VERO). Nos ensaios com células tumorais os extratos apresentaram atividade mais potente contra a linhagem de ovário (OVOCAR-3), muito mais que os padrões de ácido betulínico (comercial e isolado), o que confirma a presença de outra(s) substância(s) com atividade antitumoral presente(s) no extrato o que corrobora para a pesquisa e o desenvolvimento de um fitoterápico ao invés de um fitofármaco para ser utilizado no tratamento do câncer de ovário / The objective of this study was the standardize of Eugenia florida DC. leaves extracts and study their pharmacological activities aiming the development of a chemoterapic. To achieve this goal, studies were performed using different particle sizes, metabolic profile, as well as development and validation of analytical methodologies, cytotoxic assays and assays on tumor cells. The data obtained on this study showed that the percolation extraction method in the time of 2 hours showed the better rate of betulinic acid extraction from E. florida leaves. Despite the knowledge that the particle size directly affects the efficiency of ultrasound extraction, major differences were not observed in the percentage of betulinic acid for the different particle sizes used, however the uniformity of the particle size increases the efficiency of extraction. In the metabolic profile study, variations were observed during the year which should be considered in the quality of the vegetable raw material. E. florida extracts showed lower citotoxicity in VERO cells, and showed high selectivity index which represents a greater affinity for tumor cells than for healthy cells. In tumoral cells assays, the extracts showed stronger activity against the ovarian line (OVOCAR-3), much more than the standards of betulinic acid (commercial and isolated), which confirms the influence of (an) other substance (s) presented in the extract with antitumoral activity in the extract which defines the development of a herbal medicine instead of a herbal drug to be used for the treatment of ovarian cancer

M.Sc. (Zoology) / Ari investigation was made into the biological control of the submerged aquatic weeds Potamogeton pectinatus, Lagarosiphon major and L. muscoides in the Florida Lake, Transvaal using the Chinese grass carp Ctenopharyngodon idella (Val.) as biological control agent. The physical, chemical (including selected heavy metals), faunal and bacteriological conditions were also investigated over a period of one year. The total standing crop of P.pectinatusand Lagarosiphon spp, were reduced from an initial 0,193 kg m" 2 (wet mass) in March 1990 to 0,0338kg m-2 (wet mass) in March 1991. Reductions in the densities of the macrophytes coincided with a corresponding increase in chIorophyll-a values in the water columm of the lake. Abnormally high concentrations of the heavy metals copper, manganese, iron, nickel chromium, zinc and lead were found to occur in the lake sediments, aquatic macrophytes, ftlamentous algae, macroinvertebrate fauna as well as in organs and tissues of the perch Perea fluviatilis. These metals could be related to gold mining activities which occurred in the vicinity of the lake some years ago. Faecal bacterial counts of the water in the lake point towards the possible contamination of the lake water with domestic sewage. Ari analysis of the faeces of the numerically dominant birds which occur at the lake i.e. the coot Fulica aistata and the egyptian goose Alopochen aegyptiacus suggest that the main cause of faecal contamination of the lake's water possibly originates from these and other water birds frequenting the lake. By using the results on the physical-chemical conditions in the lake, conditions which presently prevail can be summarized as being largely that of a mesotrophic impoundment with strong tendencies towards eutrophic conditions. Secondary effects of the grass carp on the lake ecosystem was the progressive decline of weed eating birds and a slight increase in the numbers of piscivorous birds, both of which could be linked to the drastic reduction in the standing crop of the submerged weeds in the Lake. The present survey confirms the value of the Chinese grass carp as biological control agent in the management of excessive growths of submerged aquatic weeds in lakes and reservoirs in South Africa...

Canopy gaps in many forests are thought of as resetting the successional sequence due to increased light availability. In this study, canopy gaps were identified with a LiDAR digital canopy model in a Key Largo hardwood forest. Sapling structure and composition were recorded in the gaps. Weighted averaging calibration was applied to relative abundances of trees to determine the successional age optimum for each tree species, and weighted averaging regression was used to calculate inferred stand ages for each gap’s saplings. The inferred stand ages were greater in young forest gaps than in surrounding, unimpacted forest, suggesting that succession was actually advanced. Canopy heights in Key Largo were shorter than many other tropical and temperate forests, canopy gaps were smaller and therefore light availability did not vary with gap area. This suggests that the largest gaps may not be big enough to produce the light conditions required to reestablish pioneer tree species. Soil and water conditions in young forest gaps may also favor mature rather than pioneer species. Resetting of the forest successional sequence may not occur without intense disturbances such as fires or major hurricanes that remove the entire canopy and consume or erode soils.

The objective of this research was to study the impacts of large USSE facilities on wildlife movement corridors and habitat connectivity in Florida to identify important habitat patches and movement corridors significant for potential Florida panther (Puma concolor coryi) dispersal, conservation, and recovery. Large carnivores (such as Florida panther) have often been examined as conservation umbrellas for large-scale connectivity planning due to their extensive spatial requirements (Beier et al., 2006, Thorne et al., 2006). In addition, Florida panther is relatively well-studied species that have been listed as endangered under the US Endangered Species Act for over 40 years, due to habitat fragmentation and reduction. Habitat suitability was compared before and after the installation of the USSE facilities using RandomForest model developed by Frakes and Knight (in prep). The connectivity study focused on comparing current density and effective resistance (resistance distance) before and after the installations of USSE facilities and was conducted using Circuitscape 4.0. The impacts on habitat connectivity were the most substantial in the areas where the USSE facilities were installed on or around wildlife corridors, near focal areas, and in large clusters. The study has identified important linkages and new pathways that animals may try to take in order to bypass the facilities. The study has also shown that installation of USSE facilities in areas not suitable as habitat for Florida panthers, but still permeable or semi-permeable (e.g., agricultural lands), can substantially impact connectivity between focal areas. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection
