The scramble for the seas : the ballad evidence of Sir Andrew Barton

The presence and importance of the sea as a factor that has helped shape the history of England since at least the Roman invasions of 55-54 BC (less successful, incidentally, than most of Caesar’s other military ventures ...) need no particular urging or demonstration. Nonetheless, a bird’s-eye view would necessarily survey the waves of invasions and settlements that, one after the other, came dashing over the centuries upon England’s shores; not to mention the requested invasion of 1688, Angles and Saxons, Scandinavians, Normans, they all crossed the whale’s path and cast anchor in England’s green and pleasant land. In the course of this retrospective voyage through the oceans of History, one would inevitably stop at the so-called ‘Discoveries’ of the 15th-16th centuries, meet their navigators, sailors and pirates extolled by Richard Hakluyt (1553?-1616), face an anonymous crowd of merchants and witness the huge expansion of trade, largely to the benefit of the ‘discovering’ countries as prescribed by the economic Gospel Adam Smith (1723-90) would later baptize as “mercantilism”.

Description of microsporidia in simulids: molecular and morphological characterization of microsporidia in the larvae of Simulium pertinax Kollar (Diptera: Simuliidae)

IntroductionMicrosporidia constitute the most common black fly pathogens, although the species' diversity, seasonal occurrence and transmission mechanisms remain poorly understood. Infections by this agent are often chronic and non-lethal, but they can cause reduced fecundity and decreased longevity. The objective of this study was to identify microsporidia infecting Simulium (Chirostilbia) pertinax (Kollar, 1832) larvae from Caraguatatuba, State of São Paulo, Brazil, by molecular and morphological characterization.MethodsLarvae were collected at a single point in a stream in a rural area of the city and were kept under artificial aeration until analysis. Polydispyrenia spp. infection was characterized by the presence of at least 32 mononuclear spores measuring 6.9 ± 1.0 × 5.0 ± 0.7µm in persistent sporophorous vesicles. Similarly, Amblyospora spp. were characterized by the presence of eight uninucleate spores measuring 4.5 × 3.5µm in sporophorous vesicles.ResultsThe molecular analysis confirmed the presence of microsporidian DNA in the 8 samples (prevalence of 0.51%). Six samples (Brazilian larvae) were related to Polydispyrenia simulii and Caudospora palustris reference sequences but in separate clusters. One sample was clustered with Amblyospora spp. Edhazardia aedis was the positive control taxon.ConclusionsSamples identified as Polydispyrenia spp. and Amblyospora spp. were grouped with P. simulii and Amblyospora spp., respectively, corroborating previous results. However, the 16S gene tree showed a considerable distance between the black fly-infecting Amblyospora spp. and the mosquito-infecting spp. This distance suggests that these two groups are not congeneric. Additional genomic region evaluation is necessary to obtain a coherent phylogeny for this group.
