Ground-water resources of the lower Hillsboro Canal area, Southeastern Florida

This study was done to determine the amount and kinds of water being produced from the lower Hillsboro Canal Area in Palm Beach and Broward counties. All of the potable ground water being produced from the Biscayne aquifer is developed from the canal through infiltration. Rainfall in the area is the ultimate source for all of the water. Careful control and management will allow the development of large quantities of water from the canal toward Lake Okeechobee, but a fresh water head must be maintained along the contact of fresh water with sea water to prevent salt water intrusion.

Proceedings of the Nineteenth Annual Symposium on Sea Turtle Conservation and Biology, 2-6 March 1999 South Padre Island, Texas, U.S.A.

The 19th Annual Symposium on Sea Turtle Biology and Conservation was the largest to date. The beautiful venue was the South Padre Island Convention Centre on South Padre Island, Texas from March 2-6, 1999. Key features of the 19th were invited talks on the theme The Promise, the Pain, and the Progress of 50 years of Sea Turtle Research and Conservation, a mini-symposium on the Kemp's ridley and an increased emphasis on high quality poster sessions. Hosts for the meeting included Texas A&M University, the Texas Sea Grant College Program, The Gladys Porter Zoo and Sea Turtle, Inc. Co-sponsors included the National Marine Fisheries Service-Southeast Fisheries Science Center, the National Marine Fisheries Service-Protected Resources Branch, Padre Island National Seashore and the U.S. Fish and Wildlife Service. With the assistance of Jack Frazier, we were fortunate to obtain a $30,000 grant from the David and Lucile Packard Foundation. This grant provided travel support to 49 individuals from 24 nations who presented a total of 50 presentations. (PDF contains 309 pages)

Coral Remote Sensing Workshop: Proceedings and Recommendations, 17-18 September, Sheraton, Brickell Ave, Miami FL

Coral reefs exist in warm, clear, and relatively shallow marine waters worldwide. These complex assemblages of marine organisms are unique, in that they support highly diverse, luxuriant, and essentially self-sustaining ecosystems in otherwise nutrient-poor and unproductive waters. Coral reefs are highly valued for their great beauty and for their contribution to marine productivity. Coral reefs are favorite destinations for recreational diving and snorkeling, as well as commercial and recreational fishing activities. The Florida Keys reef tract draws an estimated 2 million tourists each year, contributing nearly $800 million to the economy. However, these reef systems represent a very delicate ecological balance, and can be easily damaged and degraded by direct or indirect human contact. Indirect impacts from human activity occurs in a number of different forms, including runoff of sediments, nutrients, and other pollutants associated with forest harvesting, agricultural practices, urbanization, coastal construction, and industrial activities. Direct impacts occur through overfishing and other destructive fishing practices, mining of corals, and overuse of many reef areas, including damage from souvenir collection, boat anchoring, and diver contact. In order to protect and manage coral reefs within U.S. territorial waters, the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Department of Commerce has been directed to establish and maintain a system of national marine sanctuaries and reserves, and to monitor the condition of corals and other marine organisms within these areas. To help carry out this mandate the NOAA Coastal Services Center convened a workshop in September, 1996, to identify current and emerging sensor technologies, including satellite, airborne, and underwater systems with potential application for detecting and monitoring corals. For reef systems occurring within depths of 10 meters or less (Figure 1), mapping location and monitoring the condition of corals can be accomplished through use of aerial photography combined with diver surveys. However, corals can exist in depths greater than 90 meters (Figure 2), well below the limits of traditional optical imaging systems such as aerial or surface photography or videography. Although specialized scuba systems can allow diving to these depths, the thousands of square kilometers included within these management areas make diver surveys for deeper coral monitoring impractical. For these reasons, NOAA is investigating satellite and airborne sensor systems, as well as technologies which can facilitate the location, mapping, and monitoring of corals in deeper waters. The following systems were discussed as having potential application for detecting, mapping, and assessing the condition of corals. However, no single system is capable of accomplishing all three of these objectives under all depths and conditions within which corals exist. Systems were evaluated for their capabilities, including advantages and disadvantages, relative to their ability to detect and discriminate corals under a variety of conditions.

International Workshop for Management and Trade of Caiman yacare, Gainsville, FL, 3-5 October 2002

A workshop was held 3-5 October 2002 in Gainesville, Florida, USA to discuss management, conservation and trade in Caiman yacare. Twenty five official participants represented the four yacare range states (Argentina, Bolivia, Brazil, Paraguay), Venezuela, USA, the meeting sponsors (US Fish and Wildlife Service, CITES Secretariat, Louisiana Fur and Alligator Council), TRAFFIC Sur America and Crocodile Specialist Group. A series of country reports detailing yacare management in the four range states were distributed in Spanish and English prior to the meeting and presentations on these and on general principles of crocodilian harvest, conservation and management provided the basis for the discussions. Three working groups considered: • Requirements and field techniques for field data collection. • Requirements and techniques for regulation of harvest. • Requirements and processes for regulation of trade and export. Written reports of working groups and a plenary drafting session were finalized during the meeting and distributed, with the country reports, to participants. The workshop drafted a framework for caiman management and regulation that could be used as a template and adapted for use in each range state. The meeting agreed to convene an ad-hoc working group of range state representatives to continue discussions on the harmonization of caiman management into the future.

Activación de aldehídos a,b-insaturados mediante aminocatálisis en procesos enantioselectivos. Cicloadiciones (3+2) y reacciones en cascada Michael/Henry

During the research that it is summarized in the present memory, the activation of enals via iminium ion catalysis in different transformations has been studied. Firstly, a 1,3-dipolar cycloaddition between stable azomethine ylides and a,b-unsaturated aldehydes catalyzed by a chiral imidazolidinone derivative has been optimized. Employing this methodology we have synthesized a large range of densely substituted pyrroloisoquinolines and pyrrolophthalazines with good yields and high values of diastereo- and enantioselectivity. Moreover, a mechanistic study has been carried out based on DFT calculations and experimental data which have allowed us to propose that the (3+2) cycloaddition reaction follows a sequential Michael addition/Mannich cyclization pathway. The formation of the iminium ion as a result of the condensation between the a,b-unsaturated aldehyde and the catalyst plays an essential role, regarding both reactivity and stereoselectivity. On the other hand we have developed a methodology to carry out a cascade Michael/Henry reaction followed by a sequential dehydration. Starting from simple substrates (2-nitromethylacrilates and a,b-unsaturated aldehydes) and employing a prolinol-derivative catalyst a series of quiral nitrocyclohexadienes have been synthesized.

Que mulher é essa?: identidade, política e saúde no movimento de travestis e transexuais

O objeto desta dissertação é explorar os discursos militantes relativos à diferenciação entre as identidades coletivas de travestis e transexuais no âmbito do movimento de travestis e transexuais brasileiro e sua repercussão nas demandas e proposições de políticas públicas de saúde, mais especificamente no que tange às transformações corporais. Realizei entrevistas semi-estruturadas com ativistas reconhecidas como lideranças desse movimento, tendo como principais eixos: trajetória militante, diferenciação entre travestis e transexuais, organização do movimento, agenda política, transformações corporais e demandas relativas à saúde. Além disso, realizei etnografias em encontros gerais do movimento LGBT, assim como nos específicos de travestis e transexuais, com destaque para o XVI e XVII Encontro Nacional de Travestis e Transexuais (ENTLAIDS), realizados no Rio de Janeiro em 2009 e em Aracaju em 2010; a V Conferência Regional para América Latina e Caribe da ILGA (International Lesbian and Gay Association), realizada em Curitiba em 2009; e a I Marcha Nacional Contra a Homofobia, realizada em 19 de maio de 2010 em Brasília. A partir dos resultados das entrevistas e das etnografias, busco construir um histórico do movimento de travestis e transexuais no Brasil, no qual é possível localizar a emergência das categorias identitárias e seus conflitos. Assim, minha investigação passa pela análise da relação com categorias estigmatizantes como a prostituição e, especialmente, das capacidades de incorporação ou de apropriação de discursos médicos e psiquiátricos na construção de identidades, o que inclui a influência de fatores de classe e de acesso a serviços de saúde especializados, notoriamente o processo transexualizador no SUS. A análise das principais demandas do movimento me levou a uma relação entre políticas de reconhecimento e processos de purificação. Por fim, busco compreender o processo de construção de uma carreira militante no movimento de travestis e transexuais.

Alligator Diet in Relation to Alligator Mortality on Lake Griffin, FL

Alligator mississippiensis (American Alligators) demonstrated low hatchrate success and increased adult mortality on Lake Griffin, FL, between 1998 and 2003. Dying Lake Griffin alligators with symptoms of poor motor coordination were reported to show specific neurological impairment and brain lesions. Similar lesions were documented in salmonines that consumed clupeids with high thiaminase levels. Therefore, we investigated the diet of Lake Griffin alligators and compared it with alligator diets from two lakes that exhibited relatively low levels of unexplained alligator mortality to see if consumption of Dorosoma cepedianum (gizzard shad) could be correlated with patterns of mortality. Shad in both lakes Griffin and Apopka had high levels of thiaminase and Lake Apopka alligators were consuming greater amounts of shad relative to Lake Griffin without showing mortality rates similar to Lake Griffin alligators. Therefore, a relationship between shad consumption alone and alligator mortality is not supported.

Estudo aleatório e controlado do uso clínico de um primer autocondicionante na colagem de bráquetes ortodônticos

O uso de primers autocondicionantes tem sido proposto como uma alternativa para a redução de passos clínicos. O objetivo deste estudo clínico aleatório e controlado foi avaliar a performance de um sistema autocondicionante (Transbond Plus Self-Etching Primer, 3M Unitek - SEP) comparado a um sistema multipasso convencional (Transbond XT, 3M Unitek - TBXT) de colagem ortodôntica, durante um período de 12 meses. Vinte e oito pacientes participaram deste estudo, sendo estes alocados aos grupos SEP ou TBXT de forma aleatória, através de randomização em bloco. Um total de 548 bráquetes metálicos (Micro-Arch, prescrição Alexander, GAC International, Bohemia, NY) foram colados com uso da pasta adesiva Transbond XT (3M Unitek), sendo todos os produtos manuseados de acordo com as recomendações dos fabricantes. Foram totalizados 276 bráquetes no grupo controle e 272 no segundo. Curvas de sobrevivência Kaplan-Meier e o teste log-rank (p<0,05) foram utilizados para comparar o percentual de falhas adesivas para as duas técnicas. Ao final do período foram verificadas trinta e duas falhas adesivas (bráquetes descolados), sendo 19 (6,98%) falhas quando utilizado o primer autocondicionante (SEP) e 13 (4,71%) quando usado o primer convencional (TBXT). Não houve diferença significante entre a sobrevivência dos bráquetes entre os dois grupos avaliados (log-rank test, p=0,311). Quando a influência de gênero do paciente, arco dentário e tipo dentário (anterior ou posterior) foram analisados, somente o tipo dentário foi achado significante. Bráquetes de dentes posteriores apresentaram uma maior probabilidade de falha adesiva que os colados em dentes anteriores (p=0,013) Os autores concluem que o primer autocondicionante pode ser utilizado para colagem direta de bráquetes ortodônticos sem que sua sobrevivência clínica seja afetada.

Letter and Recollections of Alexander Agassiz: The 1891 Albatross Expedition

Presented here is another in the list of historic accounts of iconic research cruises of the USFC Steamer Albatross, this a reminiscence of the renowned scientist Alexander Agassiz edited by his son G. R. Agassiz, a chapter from the volume “Letters and Recollections of Alexander Agassiz,” published in 1913. Agassiz made three major cruises in the Albatross in 1891, 1899–1900, and 1904–05, adding greatly to the world’s store of specimens and knowledge of thalasography, his favored term for oceangraphy, and specifically of the Pacific Ocean. Having made important cruises and studies with the Blake in the Caribbean, he sought to do comparable research in the Pacific. His opportunity came in 1890, and with the consent of President Benjamin Harrison, he took charge of this Albatross research cruise, paying much of the expense himself. In contrast with the other ships he had been on, he found the laboratories, equipment, and furnishings to be comparatively luxurious and extremely well appointed for his work. Further, the Albatross was then captained by Lieutenant Commander Zera Luther Tanner who seemed to take as much interest in the oceanographic research as did the scientists, and Agassiz appreciated working with him, too. Little of the original text has been altered, and readers are cautioned that some of the views expressed may reflect unfortunate prejudices of that era toward individuals, nationalities, etc.

Commercial Whaling, Especially for Gray Whales, Eschrichtius robustus, and Humpback Whales, Megaptera novaeangliae, at California and Baja California Shore Stations in the 19th Century (1854–1899)

Shore whaling along North America’s California and Baja California coasts during 1854–99 was ancillary to the offshore and alongshore American whale fishery, which had begun in the North Pacific in the early 1800’s and was flourishing by the 1840’s. From its inception at Monterey, Calif., in the mid 1850’s, the shore fishery, involving open boats deployed from land to catch and tow whales for processing, eventually spread from Monterey south to San Diego and Baja California and north to Crescent City near the California–Oregon border. It had declined to a relict industry by the 1880’s, although sporadic efforts continued into the early 20th century. The main target species were gray whales, Eschrichtius robustus, and humpback whales, Megaptera novaeangliae, with the valuable North Pacific right whale, Eubalaena japonica, also pursued opportunistically. Catch data are grossly incomplete for most stations; no logbooks were kept for these operations as they were for high-seas whaling voyages. Even when good information is available on catch levels, usually as number of whales landed or quantity of oil produced, it is rarely broken down by species. Therefore, we devised methods for extrapolation, interpolation, pro rationing, correction, and informed judgment to produce time series of catches. The resulting estimates of landings from 1854 to 1899 are 3,150 (SE = 112) gray whales and 1,637 (SE = 62) humpback whales. The numbers landed should be multiplied by 1.2 to account for hunting loss (i.e. whales harpooned or shot but not recovered and processed).

Stanford University’s John Otterbein Snyder: Student, Collaborator, and Colleague of David Starr Jordan and Charles Henry Gilbert

John Otterbein Snyder (1867–1943) was an early student of David Starr Jordan at Stanford University and subsequently rose to become an assistant professor there. During his 34 years with the university he taught a wide variety of courses in various branches of zoology and advised numerous students. He eventually mentored 8 M.A. and 4 Ph.D. students to completion at Stanford. He also assisted in the collection of tens of thousands of fish specimens from the western Pacific, central Pacific, and the West Coast of North America, part of the time while stationed as “Naturalist” aboard the U.S. Fish Commission’s Steamer Albatross (1902–06). Although his early publications dealt mainly with fish groups and descriptions (often as a junior author with Jordan), after 1910 he became more autonomous and eventually rose to become one of the Pacific salmon, Oncorhynchus spp., experts on the West Coast. Throughout his career, he was especially esteemed by colleagues as “a stimulating teacher,” “an excellent biologist,” and “a fine man.
