Anfíbios Anuros do Distrito Federal

The frogs of the Federal District of Brazil are listed and discussed as to habit, biology and ecology. The F. D is situated 22° 54' 24" S. & 43° 10' 21" W Gr. and comprises 1.356 km². Its topography includes sea-shore, maritime scrub, lagoons, plains and marsh, open slopes, forested mountains and great heads of rock. Three thousand feet of altitude are attained at two points. Fifty two different frogs occur in the F.D. Three fifths of them live in open country. Two fifths of these have never been found above the plains; the others range higher but mostly in open country. Their environment offers conditions suitable for average tadpoles and adults. these frogs are more or less unspecialized. There are six genera and thirty species. Two thirds of the latter belong to the type genera of the large neotropical families Bufonidae, Leptodactylidae and Hylidae. Only in the maritime scrub formation are conditions somewhat different. Water for average tadpoles is provided by the lagoons. The xerophytism of the vegetation is, however, so marked that bromeliads growing on the ground provide almost the only appropriate shelter for adult tree-frogs used to sleeping upright on the vegetation. One large Hylid genus lives entirely in them. It is casque-headed and phragmotic, shutting the lumen of the leaf-cup with head used as a plug. Another large Hylid genus shows a lesser degree of the same specialization. (Lutz A & Lutz B, 1939 II). One genus with two species is entirely saxicolous; it lives on wet ledges of rock at all phases of its life history. (B. Lutz 1948). The other two fifths of the frogs from F. D. are montane forest forms. Their environment offers numerous and varied biotopes and is near optimum for adults. There is,however, hardly any standing water available for larvae. These frogs are ecologically diversified. They also show a general trend towards spawning in the adult biotipe, which leads to delayed hatching, semi-aquatic and terrestrial larvae and direct development. (B Lutz, 1948). The author interprets the morphological specialization of the casque-headed Hylids and the biological specialization of the montane forest forms as adaptive. Casque-headedness and phragmosis increase protection against blood-suckers and predators. The humidity of the rain forest permits eggs, embryos and larvae to develop, unharmed, outside their usual, aquatic, environment.

Investigações sôbre infecções por enterovírus no Distrito Federal

Os autores descrevem os resultados de investigações realizadas pelo Instituto Oswaldo Cruz, com material colhido pelo Serviço de Epidemiologia de Brasília, de casos paralíticos, durante um periódo de 13 meses (janeiro de 1964 a janeiro de 1965). De um total de 47 materiais examinados, foram isoladas 28 amostras de Polivírus do tipo 1, 4 do tipo 2 e duas não-pólio. Destas, uma mostrou-se patogênica para o camundongo recém-nascido, onde as lesões histopatológicas foram compatíveis com as reproduzidas por uma amostra do grupo Coxsackie A. A distribuição por idade dos pacientes sugere a necessidade de serem os grupos etários de até, no máximo, 4 anos de idade, os que devem ser fundamentalmente atingidos por campanhas de imunização contra a poliomielite, na região estudada.

Simuliidae of Goiás state and the Federal District (Brasília): 1. A description of Simulium (Chirostilbia) dekeyseri, new species

A new Brazilian simuliid species, Simulium (Chirostilbia) dekeyseri, is described from reared adults as well as larvas and pupae. This zoophilic species has only been recorded from localities in the Cerrado region of the Central Brazilian Plateu.

Mansonella ozzardi no Território Federal de Roraima, Brasil: distribuição e achado de um novo vetor na área do rio Surumu

Um inquérito hemoscópico, conduzido entre indígenas Makuxi, pertencentes a 15 localidades da região nordeste do Território Federal de Roraima, revelou a presença de microfilárias de Mansonella ozzardi em 3,2% das 652 pessoas examinadas. O número de microfilárias nos positivos era pequeno, não ultrapassando a 18 nas amostras de sangue(20mm3) colhidas. A baixa densidade na microfilaremia e a inexistência da infecção em menores de 15 anos sugerem que a filariose está sendo adquirida pelos indígenas fora de suas aldeias, provavelmente nos garimpos de ouro situados na parte alta do rio Maú. Simulium oyapockense s.l. ou Simulium roraimense - espécie muito espalhada no norte do Território - foi reconhecido como vetor de M. ozzardi na área do rio Surumu. As fêmeas desse simulídeo, embora capazes de suportar o desenvolvimento da filária até L3, não se infectam com facilidade. Assim, numa tentativa de infecção experimental, apenas 20,6% das fêmeas alimentadas sobre um voluntário (com 12mf/20mm3 de sangue colhido da polpa digital) exibiram estádios larvares de M. ozzardi (1-2 larvas somente por exemplar infectado). A alta prevalência em índios Sanumá e Mayongong, que vivem no lado oposto do Território, aponta para a existência, na área do rio Auaris, onde se localizam esses indígenas, de um outro vetor, muito mais eficiente do que S. oyapockense s.l.

A collaborative approach for incorporating forensic case data into crime investigation using criminal intelligence analysis and visualisation

There is an increasing awareness that the articulation of forensic science and criminal investigation is critical to the resolution of crimes. However, models and methods to support an effective collaboration between these partners are still poorly expressed or even lacking. Three propositions are borrowed from crime intelligence methods in order to bridge this gap: (a) the general intelligence process, (b) the analyses of investigative problems along principal perspectives: entities and their relationships, time and space, quantitative aspects and (c) visualisation methods as a mode of expression of a problem in these dimensions. Indeed, in a collaborative framework, different kinds of visualisations integrating forensic case data can play a central role for supporting decisions. Among them, link-charts are scrutinised for their abilities to structure and ease the analysis of a case by describing how relevant entities are connected. However, designing an informative chart that does not bias the reasoning process is not straightforward. Using visualisation as a catalyser for a collaborative approach integrating forensic data thus calls for better specifications.
