Species-specific population structure in rock-specialized sympatric cichlid species in Lake Tanganyika, East Africa.

Species richness and geographical phenotypic variation in East African lacustrine cichlids are often correlated with ecological specializations and limited dispersal. This study compares mitochondrial and microsatellite genetic diversity and structure among three sympatric rock-dwelling cichlids of Lake Tanganyika, Eretmodus cyanostictus, Tropheus moorii, and Ophthalmotilapia ventralis. The species represent three endemic, phylogenetically distinct tribes (Eretmodini, Tropheini, and Ectodini), and display divergent ecomorphological and behavioral specialization. Sample locations span both continuous, rocky shoreline and a potential dispersal barrier in the form of a muddy bay. High genetic diversity and population differentiation were detected in T. moorii and E. cyanostictus, whereas much lower variation and structure were found in O. ventralis. In particular, while a 7-km-wide muddy bay curtails dispersal in all three species to a similar extent, gene flow along mostly continuous habitat appeared to be controlled by distance in E. cyanostictus, further restricted by site philopatry and/or minor habitat discontinuities in T. moorii, and unrestrained in O. ventralis. In contrast to the general pattern of high gene flow along continuous shorelines in rock-dwelling cichlids of Lake Malawi, our study identifies differences in population structure among stenotopic Lake Tanganyika species. The amount of genetic differentiation among populations was not related to the degree of geographical variation of body color, especially since more phenotypic variation is observed in O. ventralis than in the genetically highly structured E. cyanostictus.

Letters to Secretary General Drummond from Thomas Scott, July 1814

Thomas Scott (1746-1824) was a politician and judge originally from Scotland. He came to Canada in 1800 after accepting the appointment of Attorney General of Upper Canada, and in 1806 was promoted to Chief Justice of Upper Canada. The declaration of war in 1812 brought into question the loyalty of the colony’s population, who were largely born in America. As concerns over allegiance intensified, the government sought out traitors in an attempt to make an example of them and deter others. The subsequent trials of citizens accused of treason resulted in 15 convictions, including Jacob Overholser. These trials were intended to assert the authority of the state, but also to demonstrate clemency. Only 8 of the convicts were executed, with the rest being banished from the colony. Scott supported these measures, although they were largely initiated by Attorney General John Beverly Robinson. Thomas Scott retired in 1816 and died in 1824.

Sullivan Agent Confesses, [1948]

The National Seaman’s Association was a labour recruiter hiding behind a union-like name. It was run by H.N. McMaster who collected fees from companies and dues from workers. With McMaster in charge, shipping interests could claim that their seamen had a union, but ship-owners were free to push their vessels and their workers to the breaking point. In 1935, the members on the Great Lakes decided to strike. One year later, they created their own union and amalgamated with a Montreal-based independent body to create the Canadian Seamen’s Union headed by a ship’s cook who became a union leader, John Allan Patrick “Pat” Sullivan. By the late 1940s, almost all sailors on Canadian ships were CSU members. Right from its inception in 1936, Communists were prominent among the leaders of the union. Sullivan had been recruited to the Communist party that year and the union had a close rapport with the party. On June 8, 1940, Pat Sullivan was arrested because of his affiliation with the Communist party. He was incarcerated until March 20, 1942. No charges were laid, no bail was set and there was no trial. After his release, Sullivan was elected second vice-president of the Trades and Labour Congress of Canada. In 1943, Percy Bengough was elected as president and Sullivan was elected as secretary treasurer of the TLC while maintaining his role as president of the CSU. On March 14, 1947 Sullivan made a shocking announcement that he was resigning from the CSU and the Labor-Progressive Party. He claimed that the CSU was under the full control of the Communists. Within a month of this announcement, he emerged as the president of the Canadian Lake Seamen’s Union. Ship-owners never really reconciled themselves to having their industry unionized, and in 1946 there was a seamen’s strike in which the union won the eight-hour day. In 1949, the shipping companies had a plan to get rid of the union and were negotiating behind their back with the Seafarers International Union (SIU). In a brutal confrontation, led by Hal Banks, an American ex-convict, the SIU was able to roust the CSU and take over the bargaining rights of Canadian seamen. On July 15, 1948, Robert Lindsay, who was Sullivan’s Welland business agent said that to the best of his knowledge, Sullivan’s outfit, the CLSU, was under the control of some of the Steamship Companies. Lindsay had heard that there was a movement to get rid of Bengough of the Trades and Labour Congress as well as elements of the CSU. He also had heard that the CLSU wanted to affiliate with the American Federation of Labor. Lindsay’s allegations raised the questions: Were the ship-owners powerful enough to oust Percy Bengough because he supported the seamen? Could the CLSU get an affiliation with the American Federation of Labor? and Would the American Federation of Labor actually affiliate with a union that was siding with employers against a locked-out union?

Dr. Stuart D. Scott Papers, 1837-2010 (non-inclusive)

Dr. Stuart D. Scott has written extensively in the fields of prehistory and history. As an archaeologist, he has traveled to some of the most significant sites in the world, including Pompeii, Stonehenge, the Valley of the Kings, Egypt’s pyramids and the Taj Mahal. He spent nine months excavating with the Tikal Project in Guatemala before returning to the University of Arizona where he received a Ph.D. in 1963. He excavated in New Zealand as a Fulbright scholar in 1963-1964. In the fall of 1964, Dr. Scott started a long career in the Anthropology Department of the State University of New York. He taught graduate and undergraduate archaeology courses and continued his archaeological and historical research. In 1979, Scott established the Old Fort Niagara Archaeology in Progress Project at Old Fort Niagara in Youngstown, New York. For many years, he became involved with historical archaeology in western New York. It was during this work that he became interested in the Upper Canada Rebellion of 1837-1838 and its aftermath. Dr. Scott and his wife, Patricia Kay Scott, would use Christmas breaks, summer vacations, and sabbatical years to travel. They were repeatedly lured back to the South Pacific, conducting research in New Zealand, Australia and many of the Micronesian and Polynesian islands. To tell the whole story of the Rebellion and the prison exiles, they traveled extensively in Canada, the United States, England and Tasmania to collect archival research and to experience the scenes of this remarkable narrative. In 2004, Dr. Scott published To the Outskirts of Habitable Creation: Americans and Canadians Transported to Tasmania in the 1840s, which told the story of the men captured, tried, convicted, and exiled as a result of the Rebellion, also called the Patriot War. Other contributions include: • A collaboration with Dr. Charles Cazeau on the book Exploring the Unknown, Great Mysteries Reexamined published by Plenum Press in 1979 • The Patriot Game: New Yorkers and the Canadian Rebellion of 1837-1838, which appeared in New York History, Vol. 68, No.3. 1987 • A Frontier Spirit: The Life of James Gemmell published in Australiasian Canadian Studies, Vol. 25, No. 2 2007 • To the Outskirts of Habitable Creation which appeared in the Friends of the National Archives, Vol. 20, No. 1 2009 • Numerous academic journal publications • Service on conference panels • Various research papers and proposals Before retiring in 1997 and while still a resident of Buffalo, N.Y., Dr. Scott spent considerable time with Brock University President Emeritus James A. Gibson and History Professor Colin Duquemin. The three shared a love of Rebellion history. It was largely because of this connection that Brock University was chosen as the recipient of Dr. Scott’s research materials.

Reencantar a educação : a educação básica e a ressocialização dos presos

Esta dissertação teve como objetivo descrever a educação básica no contexto do sistema penitenciário de Salvador em termos de processos educacionais e da Proposta Político-Pedagógica (PPP) com vistas à ressocialização do preso. Especificamente: a) descrever a realidade educacional do sistema penitenciário; b) analisar o processo educacional, método em termos de restauração pessoal, quanto à ressocialização do apenado. Em termos de percurso metodológico, quanto à natureza da pesquisa, trata-se de um estudo qualitativo. Organizou-se a dissertação, dando-lhe coerência e direção. A fundamentação teórica foi organizada delimitando-se os pontos essenciais da investigação. Em termos de tipo de pesquisa qualitativa, trata-se de estudo de caso, o qual vai-se valer, em termos de coleta de dados, da observação, entrevistas, narrativas e análise de documentos. Há que se observar que se torna difícil a situação de reintegração social do regresso, principalmente no tocante à sua recolocação profissional, pois vive-se hoje a realidade de um desemprego generalizado com elevado contingente de trabalhadores desempregados, e que ainda na maioria das vezes ainda contam com experiência profissional. A situação torna-se difícil para uma pessoa que traz consigo o estigma de ex-presidiário, e que na maioria das vezes não tem qualquer qualificação profissional. A „recuperação‟ do preso passa pela manutenção de sua referência com o mundo exterior, tais como a família, o meio de trabalho, o bairro onde reside. Quanto mais essas referências forem afastadas (e o são), mais difícil será sua readaptação posterior à sociedade. Pode ser que, após um longo período, adaptado pelas forças de sua instituição total, o mesmo já não consiga se adaptar a uma sociedade livre.

Time-place learning in individually reared angelfish, but not in pearl cichlid

Time-place learning based on food association was investigated in the cichlids angelfish (Pterophyllum scalare) and pearl cichlid (Geophagus brasiliensis) reared in isolation, therefore eliminating social influence on foraging. During a 30-day period, food was placed in one side of the aquarium (containing three compartments) in the morning and in the opposite side in the afternoon. Learning was inferred by the number of correct side choices of all fish in each day of test (15th and 30th). During the test day fish were not fed. The angelfish learned to switch sides at the correct day period in order to get food, suggesting this species has time-place learning ability when individually reared. on the other hand, the same was not observed for pearl cichlid.

Spermiogenesis and sperm ultrastructure in Cichla intermedia with some considerations about Labroidei spermatozoa (Teleostei, Perciformes, Cichlidae)

Spermiogenesis and spermatozoal structure were studied in Cichla intermedia, a primitive species of Neotropical cichlids. The analysis shows that spermiogenesis is characterized by chromatin compaction, flagellum development, nuclear rotation, nuclear fossa formation and residual cytoplasm elimination. In the spermatozoa, the head is round, the nucleus contains highly condensed filamentous clusters of chromatin and an acrosome is absent. The nuclear fossa is slightly eccentric and shows a projection that penetrates into the nuclear outline. The proximal centriole is located in the initial segment of the nuclear fossa. The midpiece and the cytoplasmic channel are long. The mitochondria, about 10 in number, are round or slightly elongated, disposed in two layers around the initial segment of the flagellum. The flagellum has a classical 9 + 2 axoneme and two lateral fins. The data available show that no characteristics of spermiogenesis or spermatozoa are exclusively found in members of the suborder Labroidei. However, three characteristics seem to be exclusively observed in Cichlidae: (1) compact filamentous clusters of chromatin; (2) slightly eccentric nuclear fossa; and, (3) number of mitochondria.
