The Catalan countries project (1931-1939)

In the evolution of Catalan nationalism, as much politician as cultural, the period of II Spanish Republic (1931-1939) was essential. The obtaining of the Statute of Autonomy (1931-1932) supposed the beginning of a stage of expansion in multiple aspects. One of them were the contacts with the Catalanists nuclei of the rest of the cultural space of Catalan language in which, at that time, it would begin to call Catalan Countries (Balearic Islands, Valencian Country, Andorra, Rosselló, to l'Alguer). On Those Collaborations between cultural organizations, political and particular parties Catalonia always will be the model to follow. The Increasing connections will be visualized on press, as well as on cultural celebrations, policy of parties and Constituent Courts. This evolution will be cut by the Franco victory in the Civil War in 1939.

Estudo morfológico comparativo de ovos e ninfas de Triatoma maculata (Erichson, 1848) e Triatoma pseudomaculata Corrêa & Espínola, 1964 (Hemiptera, Reduviidae, Triatominae)

Utilizando a microscopia ótica (MO) e eletrônica de varredura (MEV) procurou-se fornecer dados a taxionomia através da estrutura dos ovos e morfologia das ninfas, destes vetores da doença de Chagas. Os ovos em MO apresentam a superfície exocorial do opérculo e do corpo dividida em áreas poligonais com ornamentação própria; em T. maculata o exocório do corpo tem áreas indefinidas. Em MEV o exocório dos opérculos apresenta áreas poligonais de superfície estofada com pequena sulcos irregulares e perfurações distribuídas aleatoriamente nas duas espécies. O exocório do corpo apresenta: em T. maculata áreas acolchoadas com perfurações mais numerosas nos bordos, visualizando-se a borda corial, goteira espermática, aerópilas e micrópilas; em T. pseudomaculata as áreas são planas com numerosas perfurações. Nas ninfas o sulco estridulatório e o rostro apresentam diferenças significativas. O sulco estridulatórios em MO possibilitou diferenciar ninfas de 1º, 2º e 3º estádios, os 4º e 5º estádios apresentam-se semelhantes. Em MEV a diferenciação é acentuada. O rostro em MO apresenta pilosidade característica a partir do 3º estádio. T. maculata apresenta pêlos curtos e esparsos no 1º e 2º artículos e longos e numerosos no 3º, em T. pseudo-maculata semelhantes, porém mais curtos no 3º artículo.

Orientation of the snail Biomphalaria straminea (Dunker, 1848) in response to light in a situation of selection

The behavioral response of Biomphalaria straminea to light was evaluted in terms of location of the snail in a Y-shaped aquarium in a situation of selection and of the rate (cm/hour) and direction of locomotion under homogeneous 9vertical) or differential (horizontal) lighting upon only one arm of the aquarium. The light source consisted of daylight fluorescent lamps with a spectrum close to that of natural light, with illumination varying from 28 to 350 lux. Analysis of the data showed that all animals, whether in groups or isolated, were attracted to light, although the time needed to approach the light source was 50% shorter for the former than for the latter. The rate of locomotion of B. straminea was 35% higher than observed in B. glabrata and 51% higher than that observed in B. tenagophila studied under similar conditions. The results are discussed in terms of social factors and geographical distribution of the three species.

Observações ecológicas sobre Biomphalaria straminea (Dunker, 1848) em áreas do Nordeste, Brasil

The different climatic regions determine the zoogeographic distribution of various animal species depending on their particular conditions and ecological preferences. The host schistosomiasis planorbid is one of these species. This paper deals with the distribution of Biomphalaria straminea in northeast Brazil. It starts from the analysis of different climatic peculiarities in this region, associated to limnological observation done by the author in three different hydric collections in the state of Sergipe. It has been concluded that this is an "eurióioca" species. Its broad ecological valence permits this species to survive in regions where climate asperties are evident, requiring behavior and physiological adaptations. The species survives in all northeast region, from "zona da mata", in the coast, to the semi-arid "sertão".

On Dichelyne (Cucullanellus) elongatus (Tornquist, 1931) Petter, 1974: South American correlated species (Nematoda, Cucullanidae) and some other helminths of micropogonias furnieri (Desmarest, 1823) (Pisces, Sciaenidae)

Dichelyne (Cucullanellus) elongatus (Tomquist, 1931) Petter, 1974, from Venezuela, of which D.(C.) amaurincai (Freitas, Vicente & Ibáñez, 1969) Petter, 1974 is proposed as a junior synonym, is redescribed and comments on the present status of the remaining species under the group, namely D.(C.) dichelyneformes (Szidat, 1950) Petter, 1974, D.(C.) rodriguesi (Pinto, Fábio & Noronha, 1970) Petter, 1974 and D.(C.) travassosi (Guimarães & Cristofaro, 1974), occuring in South America are made. Dollfusentis chandleri Golvan, 1969 (Acanthocephala, Illiosentidae), Poecilancistrium caryophyllum (Diesing, 1850)(Cestoidea, Otobothriidae) and Callitetrarhynchus gracilis (Rudolphi, 1819)(Cestoidea, Dasyrhynchidae) as well as larval forms of Echinocephalus sp. (Nematoda, Gnathostomatidae) and Contracaecum sp. (Nematoda, Anisakidae) are also reported.
