Detection and assessment of electrocution in endangered raptors by infrared thermography

BACKGROUND Most European birds of prey find themselves in a poor state of conservation, with electrocution as one of the most frequent causes of unnatural death. Since early detection of electrocution is difficult, treatment is usually implemented late, which reduces its effectiveness. By considering that electrocution reduces tissue temperature, it may be detectable by thermography, which would allow a more rapid identification. Three individuals from three endangered raptor species [Spanish imperial eagle (Aquila adalberti), Lammergeier (Gypaetus barbatus) and Osprey (Pandion haliaetus)] were studied thermographically from the time they were admitted to a rehabilitation centre to the time their clinical cases were resolved. CASES PRESENTATION The three raptors presented lesions lacking thermal bilateral symmetry and were consistent with electrocution of feet, wings and eyes, visible by thermography before than clinically; lesions were well-defined and showed a lower temperature than the surrounding tissue. Some lesions evolved thermally and clinically until the appearance of normal tissue recovered, while others evolved and became necrotic. A histopathological analysis of a damaged finger amputated off a Lammergeier, and the necropsy and histopathology examination of an osprey, confirmed the electrocution diagnosis. CONCLUSIONS These results suggest that thermography is effective and useful for the objective and early detection and monitoring of electrocuted birds, and that it may prove especially useful for examining live animals that require no amputation or cannot be subjected to invasive histopathology.

Edición y estudio de Bencimarte de Lusitania

La historia del invencible y clarísimo principe Bencimarte de Lusitania, emperador del gran Cairo y de otros principes de su linaje, is a handwritten Romance of Chivalries found by José Manuel Lucía Megías in the library of the Royal Palace in Madrid. There are two known copies in the forementioned library. The two copies (B1 and B2) dońt have the same content, the depth of the work is found in B1 which is selected for this thesis whereas in B2 we could only find incoherent and unconnected parts due to book binding and covering as some texts had been lost. In the present work is going to be offered a manuscript description, inner and outer features, dating issues, text variations, narrative voices and structure, chronology and worḱs primary and secondary sources, characters, summaries, arguments and what́s new according to the world of chivalry. Our initial aim was to set a conclusive text of Bencimarte de Lusitania as to it has remained unknown for the reader until nowadays. It dealt with the transcription of both manuscripts, reinterprated their contents and compared them with the original texts. On the other hand, we could make a critical edition of the final version which highlighted Bencimarte himself and its possible interpretations. Thus, we could suitably arrange the text in its period as there is no date on it by means of the text itself or any further reference. We will do the same regarding to either the author or the authors. We would study the book itself offering an interpretation and a deep analysis of its elements, both the structural ones and those that belong to Romance of Chivelries themselves (mythical and marvellous adventures, knights and ladies , prodigious characters, the topic of the found manuscript, challenges and so on) as well as what is new and unique in this work of art which means to follow a pattern apart from introducing something new in the Chivelry books...
