Comparison of genetic and morphological methods to detect the presence of American lobsters, Homarus americanus H. Milne Edwards, 1837 (Astacidea: Nephropidae) in Norwegian waters

American lobsters (Homarus americanus H. Milne Edwards, 1837) are imported live to Europe and should according regulations be kept in land-based tanks until sold. In spite of the strict regulations aimed specifically at preventing the introduction of this species into the NE Atlantic, several specimens of H. americanus have been captured in the wild, especially in Oslofjord, Norway since 1999. One of the great concerns is interbreeding between the introduced American species and the local European lobster, H. gammarus (Linnaeus, 1758). For this reason an awareness campaign was launched in 2000 focusing on morphologically "unusual" lobsters caught in local waters. Morphological characters have been based on colour and sub-ventral spines on the rostrum. Two samples of H. americanus were used for comparisons, as well as samples of European lobster from Oslofjord collected in 1992. Previous genetic analyses (allozymes, mtDNA and microsatellite DNA) have demonstrated that the American lobster is distinct from its European counterpart, with several additional alleles at many loci in addition to different allelic frequency distribution of alleles of "shared" alleles. During the present study, thirteen microsatellite loci were tested in the initial screening, and the three most discriminating loci (Hgam98, Hgam197b and Hgam47b) were used in a detailed comparison between the two species. A total of 45 unusual lobsters were reported captured from Ålesund (west) to Oslofjord (southeast) from 2001 to 2005 and these were analysed for the three microsatellite loci. Nine specimens were identified as American lobsters. Comparisons between morphological and genetic characteristics revealed that morphological differences are not reliable in discrimination the two species, or to identify hybrids. Further, some loci display almost no overlapping in allele frequency distribution for the reference samples analysed, thus providing a reliable tool to identify hybrids.

Emergencias de la mediación intelectual. "La Revista de América" (París, 1912-1914) y la red de escritores latinoamericanos en Europa a comienzos del siglo XX

Este trabajo estudia el proyecto editorial de la Revista de América (1912-1914), fundada en París y dirigida por Francisco García Calderón. Mi propósito es analizar el modo en que muchos de los vínculos entre los escritores latinoamericanos radicados en París entre fines del siglo XIX y la Primera Guerra Mundial se materializaron en la edición de revistas. Propongo examinar las estrategias de difusión de las producciones latinoamericanas en el Viejo Continente, como así también algunos aspectos ideológicos y de intervención intelectual que la revista llegó a articular. En un primer momento, me detengo en los rasgos materiales tanto del proyecto editorial de la revista como de los vínculos entre los latinoamericanos desterrados. Luego indago las distintas formas de mediación crítica, por un lado, y cultural, por otro, que la revista escenificó y, en algunos casos, desarrolló activamente. En efecto, la revista de García Calderón vuelve visible una dimensión mediadora en varios sentidos: mediación crítica entre productores y lectores, pues se propuso como instancia de difusión, al convocar a “a los mejores escritores latinoamericanos”. Al mismo tiempo, propuso otras dos mediaciones: entre pares, al funcionar como consagradora, seleccionando y agrupando simbólicamente a los escritores de cada país latinoamericano. Finalmente, una mediación intercontinental entre culturas en la contemporaneidad, que intentó acercar dos gestos en la acción de la revista: una legitimación del pensamiento y el arte “de ultramar” y una valoración de los desarrollos artísticos europeos del presente.

Integrating field sports, hare population management and conservation

Conflicts between field sports, animal welfare and species conservation are frequently contentious. In Ireland, the Irish Coursing Club (ICC) competitively tests the speed and agility of two greyhounds by using a live hare as a lure. Each coursing club is associated with a number of discrete localities, known as preserves, which are managed favourably for hares including predator control, prohibition of other forms of hunting such as shooting and poaching and the maintenance and enhancement of suitable hare habitat. We indirectly tested the efficacy of such management by comparing hare abundance within preserves to that in the wider countryside. In real terms, mean hare density was 18 times higher, and after controlling for variance in habitat remained 3 times higher, within ICC preserves than the wider countryside. Whilst we cannot rule out the role of habitat, our results suggest that hare numbers are maintained at high levels in ICC preserves either because clubs select areas of high hare density and subsequently have a negligible effect on numbers or that active population management positively increases hare abundance. The Irish hare Lepus timidus hibernicus Bell, 1837 is one of the highest priority species for conservation action in Ireland and without concessions for its role in conservation, any change in the legal status Of hare coursing under animal welfare grounds, may necessitate an increase in Government subsidies for conservation on private land together with a strengthened capacity for legislation enforcement.

Spitzer Space Telescope spectra of post-AGB stars in the large magellanic Cloud-polycyclic aromatic hydrocarbons at low metallicities

This paper reports variations of polycyclic aromatic hydrocarbons (PAHs) features that were found in Spitzer Space Telescope spectra of carbon-rich post-asymptotic giant branch (post-AGB) stars in the Large Magellanic Cloud (LMC). The paper consists of two parts. The first part describes our Spitzer spectral observing programme of 24 stars including post-AGB candidates. The latter half of this paper presents the analysis of PAH features in 20 carbon-rich post-AGB stars in the LMC, assembled from the Spitzer archive as well as from our own programme.We found that five post-AGB stars showed a broad feature with a peak at 7.7 μm, that had not been classified before. Further, the 10-13 μm PAH spectra were classified into four classes, one of which has three broad peaks at 11.3, 12.3 and 13.3 μm rather than two distinct sharp peaks at 11.3 and 12.7 μm, as commonly found in HII regions. Our studies suggest that PAHs are gradually processed while the central stars evolve from post-AGB phase to planetary nebulae, changing their composition before PAHs are incorporated into the interstellar medium. Although some metallicity dependence of PAH spectra exists, the evolutionary state of an object is more significant than its metallicity in determining the spectral characteristics of PAHs for LMC and Galactic post-AGB stars. © 2014 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society.

Commemorating Women in Irish History, 1912-1922

This is a pilot project to create a website identifying places in Ireland that relate to the history of women, 1912-1922. I have also submitted a grant application to the Heritage Lottery Fund to extend this project to a longer chronological period. This is a collaborative project with Professor Bernadette Whelan in the University of Limerick.

Maria Teresa Cortez. Os contos de Grimm em Portugal. A recepção dos Kinder-und Hausmärchen entre 1837 e 1910, Coimbra, Minerva (Centro Interuniversitário de Estudos Germanísticos) e Universidade de Aveiro, 2001. 531 pp.

Trabalho que investiga a recepção dos Kinder - und Hausmärchen em Portugal, fruto duma aturada e minuciosa pesquisa documental. Com efeito, Teresa Cortez passa em revista os livros e publicações periódicas enquadrados entre 1837 — data do aparecimento das primeiras traduções de contos dos KHM, no periódico lisboeta Biblioteca Familiar e Recreativa — e 1910, data a que a autora estendeu a sua pesquisa. Cada incidência da presença dos contos dos Grimm em Portugal é cuidadosamente investigada, contextualisada e analisada, Assim, à medida que vemos surgir, primeiro esparsas em revistas destinadas a um público infantil, e sem indicação de autoria, traduções (do francês) dos KHM, vamo-nos inteirando sobre o epírito e motivações do seu aparecimento, quer partindo do estudo comparativo com o texto de origem, quer de um exame da publicação de chegada, alargando-se a pesquisa aos seus editores e autores. Todo o processo de recepção dos contos de Grimm vai sendo examinado pela autora à luz dos movimentos das últimas décadas do séc. XIX e primeira do séc. XX, nomeadamente o nacionalismo neo-romântico e o positivismo.
