Proceedings fo the Seventeenth Annual Sea Turtle Symposium, 4-8 March 1997, Orlando, Florida, U.S.A.

The 17th Annual Sea Turtle Symposium was held at the Delta Orlando Resort in Orlando, Florida U.S.A. from March 4-8, 1997. The symposium was hosted by Florida Atlantic University, Mote Marine Laboratory, University of Central Florida, University of Florida, Florida Atlantic University and the Comité Nacional para la Conservación y Protección de las Totugas Marinas. The 17th was the largest symposium to date. A total of 720 participants registered, including sea turtle biologists, students, regulatory personnel, managers, and volunteers representing 38 countries. In addition to the United States, participants represented Australia, Austria, the Bahamas, Bonaire, Bermuda, Brazil, Canada, Colombia, Costa Rica, Croatia, Cuba, Cyprus, Dominican Republic, Ecuador, England, Guatemala, Greece, Honduras, India, Italy, Japan, Madagascar, Malaysia, Mexico, The Netherlands, Nicaragua, Peru, Philippines, Republic of Seychelles, Scotland, Spain, Sri Lanka, Switzerland, Taiwan, Turkey, Uruguay, and Venezuela. In addition to the 79 oral, 2 video, and 120 poster presentations, 3 workshops were offered: Selina Heppell (Duke University Marine Laboratory) provided “Population Modeling,” Mike Walsh and Sam Dover (Sea World-Orlando) conducted “Marine Turtle Veterinary Medicine” and “Conservation on Nesting Beaches” was offered by Blair Witherington and David Arnold (Florida Department of Environmental Protection). On the first evening, P.C.H. Pritchard delivered a thoughtful retrospect on Archie Carr that showed many sides of a complex man who studied and wrote about sea turtles. It was a presentation that none of us will forget. The members considered a number of resolutions at the Thursday business meeting and passed six. Five of these resolutions are presented in the Commentaries and Reviews section of Chelonian Conservation and Biology 2(3):442-444 (1997). The symposium was fortunate to have many fine presentations competing for the Archie Carr Best Student Presentations awards. The best oral presentation award went to Amanda Southwood (University of British Columbia) for “Heart rates and dive behavior of the leatherback sea turtle during the internesting interval.” The two runners-up were Richard Reina (Australian National University) for “Regulation of salt gland activity in Chelonia mydas” and Singo Minamikawa (Kyoto University) for “The influence that artificial specific gravity change gives to diving behavior of loggerhead turtles”. The winner of this year’s best poster competition was Mark Roberts (University of South Florida) for his poster entitled “Global population structure of green sea Turtles (Chelonia mydas) using microsatellite analysis of male mediated gene flow.” The two runners-up were Larisa Avens (University of North Carolina-Chapel Hill) for “Equilibrium responses to rotational displacements by hatchling sea turtles: maintaining a migratory heading in a turbulent ocean” and Annette Broderick (University of Glasgow) for “Female size, not length, is a correlate of reproductive output.” The symposium was very fortunate to receive a matching monetary and subscription gift from Anders J. G. Rhodin of the Chelonian Research Foundation. These enabled us to more adequately reward the fine work of students. The winners of the best paper and best poster awards received $400 plus a subscription to Chelonian Conservation and Biology. Each runner up received $100. The symposium owes a great debt to countless volunteers who helped make the meeting a success. Those volunteers include: Jamie Serino, Alan Bolton, and Karen Bjorndal, along with the UF students provided audio visual help, John Keinath chaired the student awards committee, Mike Salmon chaired the Program Commiteee, Sheryan Epperly and Joanne Braun compiled the Proceedings, Edwin Drane served as treasurer and provided much logistical help, Jane Provancha coordinated volunteers, Thelma Richardson conducted registration, Vicki Wiese coordinated food and beverage services, Jamie Serino and Erik Marin coordinated entertainment, Kenneth Dodd oversaw student travel awards, Traci Guynup, Tina Brown, Jerris Foote, Dan Hamilton, Richie Moretti, and Vicki Wiese served on the time and place committee, Blair Witherington created the trivia quiz, Tom McFarland donated the symposium logo, Deborah Crouse chaired the resolutions committee, Pamela Plotkin chaired the nominations committee, Sally Krebs, Susan Schenk, and Larry Wood conducted the silent auction, and Beverly and Tom McFarland coordinated all 26 vendors. Many individuals from outside the United States were able to attend the 17th Annual Sea Turtle Symposium thanks to the tireless work of Karen Eckert, Marydele Donnelly, and Jack Frazier in soliciting travel assistance for a number of international participants. We are indebted to those donating money to the internationals’ housing fund (Flo Vetter Memorial Fund, Marinelife Center of Juno Beach, Roger Mellgren, and Jane Provancha). We raise much of our money for international travel from the auction; thanks go to auctioneer Bob Shoop, who kept our auction fastpaced and entertaining, and made sure the bidding was high. The Annual Sea Turtle Symposium is unequaled in its emphasis on international participation. Through international participation we all learn a great deal more about the biology of sea turtles and the conservation issues that sea turtles face in distant waters. Additionally, those attending the symposium come away with a tremendous wealth of knowledge, professional contacts, and new friendships. The Annual Sea Turtle Symposium is a meeting in which pretenses are dropped, good science is presented, and friendly, open communication is the rule. The camaraderie that typifies these meetings ultimately translates into understanding and cooperation. These aspects, combined, have gone and will go a long way toward helping to protect marine turtles and toward aiding their recovery on a global scale. (PDF contains 342 pages)

Functional analysis of cancer-associated EGFR mutants using a cellular assay with YFP-tagged EGFR intracellular domain

Background: The presence of EGFR kinase domain mutations in a subset of NSCLC patients correlates with the response to treatment with the EGFR tyrosine kinase inhibitors gefitinib and erlotinib. Although most EGFR mutations detected are short deletions in exon 19 or the L858R point mutation in exon 21, more than 75 different EGFR kinase domain residues have been reported to be altered in NSCLC patients. The phenotypical consequences of different EGFR mutations may vary dramatically, but the majority of uncommon EGFR mutations have never been functionally evaluated. Results: We demonstrate that the relative kinase activity and erlotinib sensitivity of different EGFR mutants can be readily evaluated using transfection of an YFP-tagged fragment of the EGFR intracellular domain (YFP-EGFR-ICD), followed by immunofluorescence microscopy analysis. Using this assay, we show that the exon 20 insertions Ins770SVD and Ins774HV confer increased kinase activity, but no erlotinib sensitivity. We also show that, in contrast to the common L858R mutation, the uncommon exon 21 point mutations P848L and A859T appear to behave like functionally silent polymorphisms. Conclusion: The ability to rapidly obtain functional information on EGFR variants of unknown relevance using the YFP-EGFR-ICD assay might prove important in the future for the management of NSCLC patients bearing uncommon EGFR mutations. In addition, our assay may be used to determine the response of resistant EGFR mutants to novel second-generation TKIs.

Discrepancias en el seno de la burguesía guipuzcoana en torno a la libertad de comercio y el traslado de aduanas durante los siglos XVIII y XIX

[ES] El objetivo del presente artículo es demostrar y analizar las discrepancias que hubo en el seno de la burguesía guipuzcoana durante los siglos XVIII y XIX en torno a la habilitación de los puertos guipuzcoanos para el comercio directo con América y el traslado de aduanas desde el interior a la costa. Para ello, se acude a la extensa historiografía que se ha ocupado del tema y se hace un análisis crítico de cierto número de representaciones enviadas por el grupo de comerciantes disidentes, con el fin de llevar a cabo un reco- rrido por el debate en torno a ambas cuestiones, que se prolongó desde el advenimiento de la dinastía borbónica hasta los decretos de 1841. A pesar de la visión unívoca que se ha dado del mencionado debate, según la cual parti- ciparon dos bloques perfectamente diferenciados, la documentación muestra una mayor heterogeneidad en las posturas, de manera que en el seno de la burguesía comercial se perciben ciertas divisiones y discrepancias. Si bien es cierto que en un principio los bloques parecen tener un discurso claramente beligerante, aunque también existen todavía puntos de coincidencia, a medi- da que transcurre el tiempo, las posturas se van radicalizando y diversifi- cando, creando una mayor heterogeneidad.

Formation mechanism of self-organized voids in dielectrics induced by tightly focused femtosecond laser pulses

In this paper, we briefly summarize two typical morphology characteristics of the self-organized void array induced in bulk of fused silica glass by a tightly focused femtosecond laser beam, such as the key role of high numerical aperture in the void array formation and the concentric-circle-like structure indicated by the top view of the void array. By adopting a physical model which combines the nonlinear propagation of femtosecond laser pulses with the spherical aberration effect (SA) at the interface of two mediums of different refractive indices, reasonable agreements between the simulation results and the experimental results are obtained. By comparing the fluence distributions of the case with both SA and nonlinear effects included and the case with only consideration of SA, we suggest that spherical aberration, which results from the refractive index mismatch between air and fused silica glass, is the main reason for the formation of the self-organized void array.

Cooperative and market-based solutions to pollution abatement problems

This work concerns itself with the possibility of solutions, both cooperative and market based, to pollution abatement problems. In particular, we are interested in pollutant emissions in Southern California and possible solutions to the abatement problems enumerated in the 1990 Clean Air Act. A tradable pollution permit program has been implemented to reduce emissions, creating property rights associated with various pollutants.

Before we discuss the performance of market-based solutions to LA's pollution woes, we consider the existence of cooperative solutions. In Chapter 2, we examine pollutant emissions as a trans boundary public bad. We show that for a class of environments in which pollution moves in a bi-directional, acyclic manner, there exists a sustainable coalition structure and associated levels of emissions. We do so via a new core concept, one more appropriate to modeling cooperative emissions agreements (and potential defection from them) than the standard definitions.

However, this leaves the question of implementing pollution abatement programs unanswered. While the existence of a cost-effective permit market equilibrium has long been understood, the implementation of such programs has been difficult. The design of Los Angeles' REgional CLean Air Incentives Market (RECLAIM) alleviated some of the implementation problems, and in part exacerbated them. For example, it created two overlapping cycles of permits and two zones of permits for different geographic regions. While these design features create a market that allows some measure of regulatory control, they establish a very difficult trading environment with the potential for inefficiency arising from the transactions costs enumerated above and the illiquidity induced by the myriad assets and relatively few participants in this market.

It was with these concerns in mind that the ACE market (Automated Credit Exchange) was designed. The ACE market utilizes an iterated combined-value call market (CV Market). Before discussing the performance of the RECLAIM program in general and the ACE mechanism in particular, we test experimentally whether a portfolio trading mechanism can overcome market illiquidity. Chapter 3 experimentally demonstrates the ability of a portfolio trading mechanism to overcome portfolio rebalancing problems, thereby inducing sufficient liquidity for markets to fully equilibrate.

With experimental evidence in hand, we consider the CV Market's performance in the real world. We find that as the allocation of permits reduces to the level of historical emissions, prices are increasing. As of April of this year, prices are roughly equal to the cost of the Best Available Control Technology (BACT). This took longer than expected, due both to tendencies to mis-report emissions under the old regime, and abatement technology advances encouraged by the program. Vve also find that the ACE market provides liquidity where needed to encourage long-term planning on behalf of polluting facilities.

De "caldeirão do diabo" a "paraíso ecológico": a conversão da Ilha Grande

A partir de 1994, com a cessão das terras e benfeitorias do extinto Instituto Penal Cândido Mendes na Vila Dois Rios, a Universidade do Estado do Rio de Janeiro (UERJ) passou a atuar na Ilha Grande (Angra dos Reis/RJ), de forma mais expressiva, fundando o Centro de Estudos Ambientais e Desenvolvimento Sustentável (CEADS). Em função da relevância socioambiental da Costa Verde, em especial, da Ilha Grande, e dos compromissos assumidos pela universidade com a implantação do CEADS, o presente estudo buscou avaliar como a gestão desse campus pode contribuir para o estabelecimento de políticas públicas que promovam a sustentabilidade socio-ambiental da Ilha Grande. Desta forma, a partir de um diagnóstico socioambiental da Costa Verde, com ênfase na Ilha Grande, foi realizada uma reflexão crítica sobre os processos de territorialização em Dois Rios e uma apreciação dos problemas socioambientais prioritários por meio da Análise da Cadeia Causal. Identificou-se como as principais causas raízes dos problemas prioritários da Ilha Grande, a fragilidade do sistema de governança (dificuldade de implementar acordos; dificuldade de mobilização social; falta de ordenamento dos diferentes níveis de governo; inadequada integração de considerações ambientais nas políticas públicas; impunidade; corrupção, precariedade da fiscalização) e causas políticas (conflitos entre diferentes instância públicas). Evidenciou-se, também, um distanciamento entre as instituições gestoras locais e os centros de produção de conhecimento que atuam na região, entre os quais a UERJ, através do CEADS. A partir do envolvimento institucional mais forte e de uma política ambiental a ser assumida como estratégia de gestão da UERJ como um todo, propõe-se a implantação de um ecocampus na unidade de Dois Rios, que oportunize à universidade contribuir, de forma pró-ativa, para a sustentabilidade da Costa Verde, sem exclusão da população local, assim como, realizar uma ampla reflexão e reformulação de suas práticas. Palavras-chave: Ilha Grande. Turismo. Análise da Cadeia Causal. Território. Ecocampus. Sustentabilidade

Caracterização de alterações epigenéticas no gene JARID1C e desequilíbrios genéticos como causas do retardo mental ligado ao x de etiologia idiopática

O retardo mental (RM) é caracterizado por um funcionamento intelectual significantemente abaixo da média (QI<70). A prevalência de RM varia entre estudos epidemiológicos, sendo estimada em 2-3% da população mundial, constituindo assim, um dos mais importantes problemas de saúde pública. Há um consenso geral de que o RM é mais comum no sexo masculino, um achado atribuído às numerosas mutações nos genes encontrados no cromossomo X, levando ao retardo mental ligado ao X (RMLX). Dentre os genes presentes no cromossomo X, o Jumonji AT-rich interactive domain IC (JARID1C) foi recentemente identificado como um potencial candidato etiológico do RM, quando mutado. O JARID1C codifica uma proteína que atua como uma desmetilase da lisina 4 da histona H3 (H3K4), imprescindível para a regulação epigenética. Tão recente como a identificação do gene JARID1C, é a descoberta de que mudanças no número de cópias de sequências de DNA, caracterizadas por microdeleções e microduplicações, poderiam ser consideradas como razões funcionalmente importantes de RMLX. Atualmente, cerca de 5-10% dos casos de RM em homens são reconhecidos por ocorrerem devido a estas variações do número de cópias no cromossomo X. Neste estudo, investigamos mutações no gene JARID1C, através do rastreamento dos éxons 9, 11, 12, 13, 15 e 16, em 121 homens de famílias com RM provavelmente ligado ao X. Paralelamente, realizamos a análise da variação do número de cópias em 16 genes localizados no cromossomo X através da técnica de MLPA no mesmo grupo de pacientes. Esta metodologia consiste em uma amplificação múltipla que detecta variações no número de cópias de até 50 sequências diferentes de DNA genômico, sendo capaz de distinguir sequências que diferem em apenas um nucleotídeo. O DNA genômico foi extraído a partir de sangue periférico e as amostras foram amplificadas pela técnica de PCR, seguida da análise por sequenciamento direto. Foram identificadas três variantes na sequência do gene JARID1C entre os pacientes analisados: a variante intrônica 2243+11 G>T, que esteve presente em 67% dos pacientes, a variante silenciosa c.1794C>G e a mutação inédita nonsense c.2172C>A, ambas presentes em 0,82% dos indivíduos investigados. A análise através do MLPA revelou uma duplicação em um dos pacientes envolvendo as sondas referentes ao gene GDI1 e ao gene HUWE1. Este trabalho expande o estudo de mutações no gene JARID1C para a população brasileira ereforça a importância da triagem de mutações neste gene em homens portadores de RM familiar de origem idiopática, assim como, é primeiro relato científico relativo à investigação de variações no número de cópias de genes localizados no cromossomo X em homens brasileiros com RM, através da técnica de MLPA.
