Wayside Trees of Tropical Florida : a guide to the native and exotic trees and palms of Miami and tropical south Florida

Wayside Trees is an beautifully illustrated guide to Florida trees growing south of Lake Okeechobee. It covers both native and exotic species in the areas of Miami to Palm Beach on the east coast, and Naples to Fort Meyers on the west. The introduction describes environmental, cultural and economic importance of trees, while a non-technical key provides a means for even non-specialists to identify the 167 most common species. The bulk of the book consists of illustrated descriptions of the trees, arranged by plant family, and includes ecological and cultural information on each species. Lavishly illustrated with over 1200 color photographs and diagrams, the book is designed to serve homeowners, gardeners, teachers and students, as well as environmental professionals. It is also a useful guide to urban tropical trees growing outside south Florida. The authors, a botanist and a graphic artist, have 70 collective years of experience living, working, and loving the trees of south Florida.

Proton nuclear magnetic resonance investigation of the native and modified active site structure of heme proteins

Hemoproteins are a very important class of enzymes in nature sharing the essentially same prosthetic group, heme, and are good models for exploring the relationship between protein structure and function. Three important hemoproteins, chloroperoxidase (CPO), horseradish peroxidase (HRP), and cytochrome P450cam (P450cam), have been extensively studied as archetypes for the relationship between structure and function. In this study, a series of 1D and 2D NMR experiments were successfully conducted to contribute to the structural studies of these hemoproteins. ^ During the epoxidation of allylbenzene, CPO is converted to an inactive green species with the prosthetic heme modified by addition of the alkene plus an oxygen atom forming a five-membered chelate ring. Complete assignment of the NMR resonances of the modified porphyrin extracted and demetallated from green CPO unambiguously established the structure of this porphyrin as an NIII-alkylated product. A novel substrate binding motif of CPO was proposed from this concluded regiospecific N-alkylation structure. ^ Soybean peroxidase (SBP) is considered as a more stable, more abundant and less expensive substitute of HRP for industrial applications. A NMR study of SBP using 1D and 2D NOE methods successfully established the active site structure of SBP and consequently fills in the blank of the SBP NMR study. All of the hyperfine shifts of the SBP-CN- complex are unambiguously assigned together with most of the prosthetic heme and all proximal His170 resonances identified. The active site structure of SBP revealed by this NMR study is in complete agreement with the recombinant SBP crystal structure and is highly similar to that of the HRP with minor differences. ^ The NMR study of paramagnetic P450cam had been greatly restricted for a long time. A combination of 2D NMR methods was used in this study for P450cam-CN - complexes with and without camphor bound. The results lead to the first unequivocal assignments of all heme hyperfine-shifted signals, together with certain correlated diamagnetic resonances. The observed alternation of the assigned novel proximal cysteine β-CH2 resonances induced by camphor binding indicated a conformational change near the proximal side.^

Androgyny versus Patriarchy: A Historicist‐Psychoanalytic Reading of Hemingway's The Garden of Eden and Wilkie Collins's The Woman in White

This paper will examine how male and female character interactions in Ernest Hemingway’s The Garden of Eden and Wilkie Collins’s The Woman in White expose the internalization, normalization, and perpetuation of current modes of patriarchy in terms of gender roles through their presentations of androgyny. This paper highlights the parallels of gender construction and the interaction within the social relations depicted in these two novels, which have not been compared previously. The premise, based on the psychoanalytic theories of Jacques Lacan and cultural materialism of Raymond Williams, is that fiction reflects historical and contemporary social relations. Lacanian and feminist interpretations have both been conducted on literature written by Collins and Hemingway; however, neither look at these particular novels as two examples for the same contemporary phenomenon of 21st century patriarchal interpellation. This paper most similarly follows the work of Slavoj Žižek who analyzes contemporary social relations through film (including classics such as Casablanca and works by Alfred Hitchcock) and other aspects of popular culture. This project’s contribution and uniqueness lie with the way it applies theory to these particular literary works, specifically concerning gender relations and the prevalence of androgyny in widely read works by well-known authors in two very different literary and historical eras. My interpretation of these two novels provides an evaluation of historical and contemporary patriarchal norms and a radical potentiality for subverting the idea of static gender roles that has remained prevalent throughout the three centuries of these texts’ existence.

SANTA ANA: UN CASO DE SUBURBANIZACIÓN EN LA AGLOMERACIÓN METROPOLITANA

El objetivo principal del trabajo es dilucidar los problemas de un pequeño centro urbano del Valle Central de Costa Rica que por su cercanía a San José, capital política del país, ha venido sufriendo el impacto del proceso de metropolización. Esta influencia comienza a ejercerse desde mediados del siglo actual, tanto en lo que se refiere al uso de la tierra como al valor del suelo, a la reducción de los terrenos dedicados a labores agrícolas en provecho de una ampliación de nuevas áreas residenciales, comerciales, etc. Pretende, también generar una metodología operacional que permita describir, empíricamente, los cambios producidos en un área suburbana de San José. Con ello se intenta llegar a determinar las condiciones generales  de los problemas del crecimiento metropolitano. Se espera, en fin, demostrar que la aplicación del método geográfico, al suministrar  una serie de datos integrados y correlacionados de aspectos naturales y sociales, sirve para medir el impacto del desarrollo tecnológico y conocer mejor los recursos. Es decir, apreciar las posibilidades y las limitaciones para el cambio. Después de enunciar varios supuestos teóricos generales, viene una descripción interpretativa del área metropolitana josefina, especialmente considerando el incremento natural de su población, la atracción de migrantes y el proceso de conurbación y suburbanización. El Cantón de Santana y su núcleo urbano se encuentra a no más de 15km del centro de San José y se llega a el por una carretera pavimentada que va pegada al pie  de las serranías del borde sur del Valle Central. La  ciudad se asienta en la planicie , que se presenta aquí como una  rinconada cavada entre los cerros; pero el nuevo impulso  residencial ha empezado a trepar  por los lomeríos de baja altura  y suave pendiente que marcan  la transición entre la llanura y la montaña. El clima es ligeramente más seco  que el de San José, porque el área se ubica a la sombra de los vientos húmedos del Pacifico y aunque siempre se distinguen una estación seca y otra húmeda, hay una acentuación marcada de la primera. La deforestación del área  circulante ha hecho evidente el peligro  de deslizamientos por rexistasia. Las tasas de incremento intercensal y natural de la población muestran valores superiores a la medida nacional tanto a nivel cantonal como distrital. Y de una tasa de migración neta negativamente en los años 50, ha pasado a tener una tasa positiva en los años actuales y es notable y muy variado el grupo  de extranjeros residentes. Santa Ana puede definirse hoy como una ciudad dormitorio, lo que se demuestra por las características de la PEA y de la planta funcional de la pequeña ciudad dentro del proceso de suburbanización; el sector comercial muestra un crecimiento entre 1972 y 1979 y una cierta especialización. La especialización agrícola ha venido acentuándose también por la importancia que ha adquirido el cultivo de hortalizas. Los centros recreacionales y de ocio para los habitantes del área  metropolitana han tomado auge, sobre todo el mayor número de días de sol que presenta el área; dos proyectos en desarrollo de parques naturales, a uno de los cuales se trasladará el zoológico nacional, le agregarán mayor atractivo. Sin embrago, la actividad industrial es pequeña y las que existen son de tipo tradicional, especialmente la fabricación de objetos de cerámica, muebles y otras.

Experimental and statistical investigation of Australian native plants for second-generation biodiesel production

This work explores the potential of Australian native plants as a source of second-generation biodiesel for internal combustion engines application. Biodiesels were evaluated from a number of non-edible oil seeds which are grow naturally in Queensland, Australia. The quality of the produced biodiesels has been investigated by several experimental and numerical methods. The research methodology and numerical model developed in this study can be used for a broad range of biodiesel feedstocks and for the future development of renewable native biodiesel in Australia.

Priority threat management of non-native plants to maintain ecosystem integrity across heterogeneous landscapes

Invasive non-native plants have negatively impacted on biodiversity and ecosystem functions world-wide. Because of the large number of species, their wide distributions and varying degrees of impact, we need a more effective method for prioritizing control strategies for cost-effective investment across heterogeneous landscapes. Here, we develop a prioritization framework that synthesizes scientific data, elicits knowledge from experts and stakeholders to identify control strategies, and appraises the cost-effectiveness of strategies. Our objective was to identify the most cost-effective strategies for reducing the total area dominated by high-impact non-native plants in the Lake Eyre Basin (LEB). We use a case study of the ˜120 million ha Lake Eyre Basin that comprises some of the most distinctive Australian landscapes, including Uluru-Kata Tjuta National Park. More than 240 non-native plant species are recorded in the Lake Eyre Basin, with many predicted to spread, but there are insufficient resources to control all species. Lake Eyre Basin experts identified 12 strategies to control, contain or eradicate non-native species over the next 50 years. The total cost of the proposed Lake Eyre Basin strategies was estimated at AU$1·7 billion, an average of AU$34 million annually. Implementation of these strategies is estimated to reduce non-native plant dominance by 17 million ha – there would be a 32% reduction in the likely area dominated by non-native plants within 50 years if these strategies were implemented. The three most cost-effective strategies were controlling Parkinsonia aculeata, Ziziphus mauritiana and Prosopis spp. These three strategies combined were estimated to cost only 0·01% of total cost of all the strategies, but would provide 20% of the total benefits. Over 50 years, cost-effective spending of AU$2·3 million could eradicate all non-native plant species from the only threatened ecological community within the Lake Eyre Basin, the Great Artesian Basin discharge springs. Synthesis and applications. Our framework, based on a case study of the ˜120 million ha Lake Eyre Basin in Australia, provides a rationale for financially efficient investment in non-native plant management and reveals combinations of strategies that are optimal for different budgets. It also highlights knowledge gaps and incidental findings that could improve effective management of non-native plants, for example addressing the reliability of species distribution data and prevalence of information sharing across states and regions.

Demonstration reaches: Looking back whilst moving forward with river rehabilitation under the Native Fish Strategy

‘Demonstration reaches’ are sections of river where multiple threats to native fish are addressed through river rehabilitation and strong community participation. They are an important way of promoting the key driving actions of the Murray-Darling Basin Authority's Native Fish Strategy (NFS) by using on-ground community-driven rehabilitation. Measuring rehabilitation success against well-defined targets and using this information to adaptively mange activities is fundamental to the demonstration reach philosophy. Seven years on from the establishment of the first demonstration reach, there are now seven throughout the Murray-Darling Basin (MDB), all in differing states of maturation and but all applying a standardised framework for monitoring native fish outcomes. In this study, we reflect on the role that demonstration reaches have played within the NFS, synthesise some key findings from 32 monitoring and evaluation outputs, and highlight some of the successes and barriers to success. We make recommendations as to how to strengthen the demonstration reach model to ensure it remains a relevant approach for fish habitat rehabilitation beyond the NFS and MDB.

Garden of Shrinking Violets

Description of the work Garden of Shrinking Violets is a collection of six half scale garments and three illustrations, continuing the practice-led research project into design for disassembly, developed in the work Shrinking Violets (2015). All garments are constructed in laser cut modules that enable the items to be reassembled in new combinations. The project extended the materials used to include ahimsa (peace) silk, silk organza and silk twill. The pattern pieces have internal laser cut grids of 5mm circles, allowing the textiles to be layered, threaded and knotted to achieve rich embellished surfaces that play with the transparencies and colour overlays of the sheer and opaque silks. Research Background Conceptually grounded in design for sustainability, the aim of the work is to develop approaches to garment construction that could allow users to engage with the garments by adding, removing and reconfiguring elements. This approach to design considers the use and end-of-life phases of the transient fashion garment through considering how the garments can be later disassembled. Research Contribution This construction process is unique in being not only a patterning device but also integral to the garment’s construction. This work sits at the intersection of technical design and craft: the laser cutting and technical approach to developing new forms of garment construction is coupled with the artisanal approach of hand-knotting, a reference to traditional quilting techniques, as a method to layer and pattern the textiles. The technique developed in Shrinking Violets was extended to experiment with different grid structures, knotting devices, and decorative fringing. The result is a proposed construction system in which the laser cut grid and knotting form a decorative patterning device, but are also integral to the garments’ construction. Research Significance Garden of Shrinking Violets was exhibited at artisan gallery’s Ivory Street window, Brisbane, January 18 – February 28 2016. The work was selected by artisan gallery exhibition curators. As part of artisan gallery’s public programming, the author participated in a panel discussion: ‘Constructive conversations: deconstruction and reconstruction in contemporary craft and design’ with jeweller Elizabeth Shaw and visual arts lecturer Courtney Pedersen, 20 February 2016.

Channel Islands Deep Water Monitoring Plan Development Workshop Report April 26-27, 2005 University of California, Santa Barbara

In 2003, twelve marine protected areas were established in state waters (0-3 nmi) surrounding the Channel Islands. NOAA is considering extending this network (3-6 nmi) into deeper waters of the Channel Islands National Marine Sanctuary (CINMS). In order for effective long-term management of the deep water reserves to occur, a well-structured monitoring program is required to assess effectiveness. The CINMS and the National Marine Sanctuary Program (NMSP) hosted a 2-day workshop in April 2005 to develop a monitoring plan for the proposed federal marine reserves in that sanctuary. Conducted at the University of California at Santa Barbara, participants included scientists from academic, state, federal, and private research institutions. Workshop participants developed project ideas that could answer priority questions posed by the NMSP. This workshop report will be used to develop a monitoring plan for the reserves.
