There are now 91 records of individual Nathusius' pipistrelle Pipistrellus nathusii examined 'in the hand' in the U.K., and bat detector records from a further 36 localities in Britain and Ireland. These records are distributed throughout all months of the year with clear peaks in spring and autumn suggesting migratory movements into and out of the British Isles in autumn and spring, respectively. Three maternity colonies have been located and the species must now also be regarded as a resident breeding species in Britain and Ireland.

With the impetus that has led recent studies on Latin American Modernism to a reevaluation of the sense of cultural fluxes from the modernity capitals to its peripheries –discarding categories such as “influence”, “exotism” and “ivory tower”, stereotypes that have clouded critical understanding of this aesthetics for decades- the present study intends to investigate a persistent practice of the main writers of the movement. This practice is modernist pictorial criticism, a genre that will be approached through the analysis of an unknown corpus: the seven chronicles Rubén Darío published in the journal La Prensa on occasion of the third art exposition of the Ateneo de Buenos Aires. Our hypothesis is that the rare creators of images portrayed by Darío by the end of 1895 work as a visual counterpoint of the eccentric writers’ biographical sketches that a year later will be part of the fundamental volume Los raros (1896). In this early “salon”, which we reproduce in its entirety, accompanied by explanatory notes, the leader of Modernism rehearses and consolidates his transcultural work with the universal tradition –now applied to the Salons (1845-1860) by Charles Baudelaire and to the monumental project by John Ruskin in Modern painters (1843-1860)- to legitimate, from another subgenre of Modernist criticism, a new figure of the critic, in dissent with the Enlightenment model of the writer.

The classification of a microsporidian parasite observed in the abdominal muscles of amphipod hosts has been repeatedly revised but still remains inconclusive. This parasite has variable spore numbers within a sporophorous vesicle and has been assigned to the genera Glugea, Pleistophora, Stempellia, and Thelohania. We used electron microscopy and molecular evidence to resolve the previous taxonomic confusion and confirm its identification as Pleistophora mulleri. The life cycle of P. mulleri is described from the freshwater amphipod host Gammarus duebeni celticus. Infection appeared as white tubular masses within the abdominal muscle of the host. Light and transmission electron microscope examination revealed the presence of an active microsporidian infection that was diffuse within the muscle block with no evidence of xenoma formation. Paucinucleate merogonial plasmodia were surrounded by an amorphous coat immediately external to the plasmalemma. The amorphous coat developed into a merontogenetic sporophorous vesicle that was present throughout sporulation. Sporogony was polysporous resulting in uninucleate spores, with a bipartite polaroplast, an anisofilar polar filament and a large posterior vacuole. SSU rDNA analysis supported the ultrastructural evidence clearly placing this parasite within the genus Pleistophora. This paper indicates that Pleistophora species are not restricted to vertebrate hosts.

Aim To examine the effect of climate change on the occurrence and distribution of Pipistrellus nathusii (Nathusius' pipistrelle) in the United Kingdom (UK).Location We modelled habitat and climatic associations of P. nathusii in the UK and applied this model to the species' historical range in continental Europe.Methods A binomial logistic regression model was constructed relating the occurrence of P. nathusii to climate and habitat characteristics using historical species occurrence records (1940-2006) and CORINE land cover data. This model was applied to historical and projected climate data to examine changes in suitable range (1940-2080) of this species. We tested the predictive ability of the model with known records in the UK after 2006 and applied the model to the species' known range in Europe.Results The distribution of P. nathusii was related positively to the area of water bodies, woodland and small areas of urbanization, and negatively related to the area of peat/heathland. Species records were associated with higher minimum temperatures, low seasonal variation in temperature and intermediate rainfall. We found that suitable areas have existed in the UK since the 1940s and that these have expanded. The model had high predictive power when applied to new records after 2006, with a correct classification rate of 70%, estimated by receiver operating characteristic analysis. Based on climate projections, our model suggests a potential twofold increase in the area suitable for P. nathusii in the UK by 2050. The single most influential climate variable contributing to range increase was the projected increase in minimum temperature. When applied to Europe, the model predictions had best predictive capability of known records in western areas of the species' range, where P. nathusii is present during the winter.Main conclusions We show that a mobile, migratory species has adapted its range in response to recent climate change on a continental scale. We believe this may be the first study to demonstrate a case of range change linked to contemporary climate change in a mammal species in Europe.

We describe the most westerly known maternity colony of Nathusius' pipistrelle bats (Pipistrellus nathusii). The bats were identified by using morphometric measurements and analysis of time-expanded echolocation and social calls. The roost, containing approximately 150 individuals, was located in a mid 19th century farm stable block and store house situated in parkland in County Antrim, Northern Ireland. The roost was visited on 30 April, I May and 22 June 1997. Over this period, 11 bats were caught: one adult male, five pregnant females, four lactating females and a juvenile male. Direct observation of behaviour patterns suggests that mating groups of P. nathusii may occur in Ireland as late as May. The migratory nature of this species is discussed.

Fish belonging to the genus Macroramphosus are distributed throughout the Atlantic, Indian and PaciWc oceans. Some authors consider this genus monotypic, Macroramphosus scolopax being the only valid species. Other authors consider (based on several morphological and ecological characters) that another species (Macroramphosus gracilis) exists and occurs frequently in sympatry with the Wrst one. Intermediate forms are also reported in literature. In this paper, using the mitochondrial control region and the nuclear Wrst S7 intron markers, we failed to Wnd genetic diVerences between individuals considered to belong to both species as well as the intermediate forms. Our results suggest that in the northeastern Atlantic, Macroramphosus is represented by a single species, M. scolopax, with diVerent morphotypes interbreeding in the sampling areas.

abstract : Taking as a starting point the association between embroidery and language conveyed by the Greek myth of Filomela and Procne, this article examines the relationship between social status and ornaments like embroidery and lace. In order to illustrate this relationship an example is selected form the letters exchanged between the Marquise of Alorna and her Father where a connection is established between the production of these 'feminine' crafts, women's culture and womens writing, in the XVIIIth Century

O texto expressa uma reflexão sobre a obra Triste Fim de Policarmo Quaresma, escrita em 1915, por Lima Barreto, escritor realista, brasileiro. Busca identificar nas narrativas e ações do seu narrador, um homem comum, as revoltas, mas também as esperanças dos homens comuns no recém criado regime republicano. Enfoca ainda que, apesar dos episódios narrados, dos personagens serem construções ficcionais do autor, nos remetem a personagens, diálogos e espaços do Rio de Janeiro que evocam a historia de um regime ditatorial de Floriano Peixoto, no alvorecer da Republica. Nesse regime, mostra o autor, que a insegurança, a insatisfação e o medo tomaram conta da população do Rio de Janeiro no começo do século XX. E Policarpo Quaresma, o personagem narrador da obra, sofrera as injustiças e arbitrariedades da ditadura do Marechal Floriano Peixoto. Diante disso, revela sua dor e plena desolação com a Republica, forma de governo pelo qual lutara e que ajudara a criar. Por fim, o texto procura mostrar que embora a literatura seja tecida com adornos da ficção, ela traduz a sociedade e o tempo no qual ela foi produzida, além de mostrar que o positivismo sustentava a pratica política da Republica brasileira.
